Blackboard nano has many advantages, the following is a specific introduction: Excellent writing performance Like traditional writing experience:The surface of the touch screen chalkboard is specially treated and uses nano coating technology to make it comfortable to write, very similar to the feeling of writing on a traditional blackboard. Whether it is the smoothness of writing or the texture of the brushstrokes, it can make the user feel natural and smooth, and can adapt well to the daily writing habits. Low dust and no pollution:When writing with ordinary chalk, the electronic chalk board produces very little dust. This is because the characteristics of the nano coating make the chalk ash not easy to fly, and most of the dust will settle naturally, which greatly reduces the dust content in the air, effectively improves the air quality in the classroom, and protects the respiratory health of teachers and students. At the same time, it also reduces the workload of cleaning after class and keeps the classroom environment clean and tidy. Outstanding display High Definition Rendering:The smart blackboard is equipped with a high-resolution display screen, which can display a variety of teaching content in clear and detailed picture quality. Whether it's text, images, or videos, they can present rich details and vibrant colors, providing students with a high-quality visual experience that helps to enhance the appeal and appeal of teaching content. Wide viewing angle for good visibility:It has a wide viewing angle, so that no matter where the student sits in the classroom, he can clearly see the content on the blackboard. This ensures that all students can get good viewing results and avoids the sit

Nano chalkboard, also known as nano smart blackboard, nano touch blackboard, etc., is a new intelligent teaching device that integrates various advanced technologies such as nanotechnology. It is mainly used in educational and teaching scenarios, providing teachers and students with richer Efficient and convenient teaching experience. Structural features Multi-layer structure:It is generally composed of multiple functional layers such as nanotouch layer and liquid crystal display layer. The nanotouch layer adopts advanced nanomaterials and processes, making the touch more sensitive and accurate, and can realize multi-touch, meeting the various operational needs of teachers and students on the blackboard. All-in-one design:The writing function of traditional blackboards is organically combined with the display function of modern electronic display devices. Seamless splicing technology is usually used to make the surface of the blackboard look flat and smooth, without obvious splicing marks, and the overall visual effect is good. Function Smart Writing & Erasing:It supports a variety of writing methods, such as hard pen writing, soft pen writing, etc., with realistic writing effects and smooth lines. At the same time, the erase method is also more convenient. It can be erased through gesture erasing, eraser tools, etc., and can realize local erasing and complete erasing. It can also undo and restore the written content. Multimedia Display:You can connect external devices such as computers, projectors, cameras, etc. to display teaching resources in various formats such as pictures, videos, audios, and documents to enrich the presentation of teaching content and improve the fun and attractiveness of teaching.

As a teaching and office equipment that integrates modern information technology, smart board for teaching has been used more and more in education, business and other fields in recent years. However, in the end, whether to introduce a interactive whiteboard for classroom, we have to think clearly about the benefits and existing problems it brings. Significant benefits from digital whiteboards Education field ⅠStimulate interest in learning: In the past, I used to use the blackboard to teach class, which was to write and draw, and the form was too simple. The smart whiteboard is different, it can integrate animation, video, audio, etc., so that the teaching content becomes super rich. Let's talk about geography class, the teacher used the smart whiteboard to play a video of the volcanic eruption, and the picture and sound immediately attracted the students' attention, and the students' interest in geography was raised. It would be very difficult to explain this abstract natural phenomenon so vividly using traditional teaching methods. Ⅱ Improving Teaching Efficiency:In the past, the teacher used to spend time on the board book in class, not to mention the slow writing, and the charts and images of complex points were not easy to draw. With the smart whiteboard, teachers can store courseware and materials in advance, and they can use it in class, saving a lot of writing time, and spending more time teaching knowledge and interaction with students. Like in a math class, the teacher can immediately show the dynamic changes of the function image to help students understand those abstract mathematical concepts, which was not possible when using the blackboard in the past. Ⅲ Support for Personalized Learning:The smart whiteboard can record the performance of students

The smart board for classroom is already an indispensable tool for modern teaching, but there are often many friends who react that the interactive whiteboard for classroom is not very obedient in the process of use, for example, the handwriting written under normal conditions cannot be displayed, the working status indicator light is not lit, and the "buzzing" sound is emitted when used, so that users are confused. In fact, users don't have to worry too much about these problems, as long as you usually take more care of "her" in the process of use and operation, coupled with proper maintenance and maintenance, I believe that "she" will not fail. Let's take a look at the basic maintenance matters during the use of the smart board interactive whiteboard. The first is the maintenance of the electronic whiteboard surface.The board surface is the main part of the electronic whiteboard and an important display part, and its maintenance needs to start from two aspects: daily use and cleaning. During the use of the whiteboard, it is best not to let anything come into contact with the board except for special pens or writing instruments, because their contact with the whiteboard can produce electronic interference and cause damage to the board surface. This will make it impossible to record some operations on the electronic whiteboard when used in the future. Of course, if it comes into contact with the magnet, it will also make a "buzzing" sound, which will affect the normal use of the whiteboard. Because the surface of the electronic whiteboard is generally a high-quality wear-resist

Do you know how an digital whiteboard makes learning fun? If you don't know, then let me answer it for you.Here are just a few ways interactive whiteboard for classrooms can make learning fun: Intuitive and vivid content display Multimedia resource display The smart board for teaching makes it easy to display multimedia materials such as video, audio, and animation. For example, when teaching the principles of volcanic eruptions in natural science, showing a shocking volcanic eruption video allows students to visually see the scene of magma eruption and volcanic ash, which is far more attractive than a simple text explanation. When explaining classical music, the classic repertoire is played directly through the whiteboard, so that students can feel the rhythm, melody and other elements of the music while enjoying the music, which greatly enhances the interest of the learning content. For abstract concepts, such as geometric transformations in mathematics, animation can dynamically display the transformation processes such as translation, rotation, and symmetry. Students can clearly see how the graphics move and change in space, making abstract mathematical knowledge visual, just like watching a fun graphic magic show, stimulating students' curiosity and desire to explore. Diverse presentations Teachers can use a variety of tools on the whiteboard, such as pens of different colors, drawing tools of various shapes, etc., to present knowledge. When explaining the relationship between characters in literary works, lines and graphics of different colors are used to represent the relationship between characters, such as

How the hardware part works Touch technology principle Capacitive touch technology is a common way to use interactive whiteboard for classrooms. There is a transparent layer of conductive material inside the whiteboard, which changes the capacitance at the touch point when a conductive object such as a finger touches the surface of the whiteboard. Whiteboard's touch detection system is able to sense this change in capacitance and calculate the position coordinates of the touch point through complex circuitry and algorithms. This technology supports multi-touch, which can accurately recognize the position and motion of multiple touch points, such as zooming, rotating, and other gestures at the same time. Electromagnetic touch technology relies on the principle of electromagnetic induction. There is a coil inside the electronic pen, and there is an electromagnetic induction layer inside the whiteboard. When the pen approaches or touches the whiteboard, the electromagnetic induction layer of the whiteboard detects the electromagnetic signal emitted by the pen and determines the position of the pen. This method of writing has high accuracy, can well simulate the real writing experience, and is suitable for precise drawing and other operations. Signal Conversion & Transmission Signals, whether they are generated by touch or electromagnetic induction, need to be converted. Touch signals are converted into digital signals that include information such as the location of the touch point, the type of touch (tap, swipe, etc.). The digital signal is then transmitted to the computer or smart device connected to it via a communication interface such as USB, Bluet

Definition Smart digital whiteboard is a high-tech product that combines electronic whiteboard technology, computer technology and touch technology. It is an electronic display device that usually resembles a traditional whiteboard in appearance, but its surface can be operated by touch, sensor pen, etc. Features: Writing Function:You can use a special stylus or finger to write on the surface of the whiteboard, and the handwriting is as clear and fluid as if you were writing with a marker pen on a traditional whiteboard. And the color, thickness and other parameters of the handwriting can usually be adjusted freely, so that users can highlight the key content. For example, in teaching scenarios, teachers can use different colors of handwriting to mark different types of knowledge points, red for important formulas, blue for example explanations, etc. Multimedia Display:Ability to display multimedia files in a variety of formats. For example, you can directly play video and audio files, display pictures, PPT (PowerPoint), etc. This makes teaching, meetings and other scenarios more vivid and rich. Taking teaching as an example, teachers can play a video of natural phenomena on the smart board for teaching to help explain scientific knowledge, so that students can understand abstract concepts more intuitively. Interactive features:Support multiple people to operate at the same time. In class, students can walk up to the podium, answer questions on the whiteboard, participate in interactive games, etc. In a business meeting, different participants can also modify and annotate th

The following are the differences between interactive and traditional whiteboards. Functional features Interactivity: Digital whiteboard: It has a strong interactive function. Users can directly operate on the whiteboard by touching, electronic pen, etc., such as dragging, zooming, rotating and other actions on the elements in the courseware. For example, in teaching, teachers can drag a geometric figure to the position at will to change the shape size, so that students can more intuitively understand the change process of the shape. Moreover, it can be connected to computers, projectors and other equipment to feed back the operation to the display screen in real time, so as to realize human-computer interaction and dynamic display of teaching resources. Traditional Whiteboard:The function is relatively simple, mainly as a writing platform, through the whiteboard pen on the surface of the whiteboard for writing and simple erasure. It does not have complex interactive functions like an interactive whiteboard for classroom, and is basically a static display, mainly relying on teachers to manually write words and draw simple graphics to convey information. Multimedia Integration: Interactive whiteboard for classroom:1. Able to seamlessly integrate a variety of multimedia resources, such as video, audio, animation, etc. Teachers can directly insert video files into the whiteboard software, play relevant videos to assist teaching when explaining knowledge points, and can also embed web links to open web pages for content expansion at any time. Traditional Whiteboard:2. It does not have the function of integrating multimedia resources, and it needs to use external equipment to display mult

Do you know how to connect to an digital whiteboard? So let me show you how. Here are the general steps to connect to an interactive whiteboard for classroom: Hardware connections 1. Power connection  1. First, make sure the electronic whiteboard is plugged in. Locate the power cord that came with the whiteboard and plug one end into the whiteboard's power connector, which is usually on the side or back of the whiteboard and has a clear power mark. Then plug the other end of the power cord into a suitable electrical outlet. 2. Connect with a computer USB connection:1. Many interactive whiteboards can be connected to a computer via a USB cable. Locate the USB port for the whiteboard (typically a standard Type A or Type B port) and the USB port available on your computer. Plug one end of the USB cable into the USB port of the whiteboard and the other end into the USB port of your computer. This connection method is mainly used to transmit data such as touch signals, so that the computer can recognize the operation of the whiteboard. VGA/HDMI connection (Video signal) :2. If the interactive whiteboard needs to display the screen of the computer, it needs to be connected to the video signal. For older whiteboards, a VGA cable may be used for the connection. Plug one end of the VGA cable into your computer's VGA output (usually blue) and the other end into the whiteboard's VGA input. For newer whiteboards that support high-definition displays, an HDMI cable connection is more recommended. Plugging one end of the HDMI cable into your computer's HDMI output and the other end into the whiteboard's HDMI input provides higher quality video tran

When people first see an digital whiteboard, they have questions. How do I open the interactive whiteboard for classroom?Different brands and models of smart board for teachings may open differently, the following are the general steps: Connect the power supply and the device 1. First make sure that the electronic whiteboard has been properly connected to the power supply. Generally, the electronic whiteboard will have a special power cord that plugs into a suitable electrical outlet. 2. Check the connection between the electronic whiteboard and the computer. This is usually done via a USB cable or HDMI cable. If you are connecting via a USB cable, make sure that the USB port is securely connected; If you are connected to an HDMI cable, in addition to connecting the cable, you should also make sure that the computer's display settings are correct and that the electronic whiteboard is an external display device. Turn on your device 1. Locate the power button on the electronic whiteboard. The position of the power button varies depending on the brand and model, and may be on the side, underneath the whiteboard, or somewhere on the bezel. Some power buttons may be clearly marked, such as a circular button with the word "Power" next to it or a power symbol (similar to "|" and "〇"). 2. Press the power button to turn on the electronic whiteboard. During the opening process, the whiteboard may have some splash screens or indicators flashing, which is normal and indicates that the device is starting up.

Teaching preparation stage Familiar with the digital whiteboard function 1. Teachers need to have a deep understanding of the various functions of the interactive whiteboard for classroom. For example, they need to understand the characteristics and uses of different writing tools, such as pens, highlighters, and brushes, as well as how to adjust the color and thickness of handwriting. At the same time, they need to master the use of erasing tools, including partial erasing and full erasing. 2. Learn to use graphic drawing tools and be able to quickly draw geometric shapes such as circles, squares, triangles, etc., which is very useful for teaching subjects such as mathematics and science. For example, when teaching the properties of geometric shapes, you can draw shapes directly on the whiteboard for demonstration. 3. Master multimedia insertion functions, such as inserting pictures, videos, audio, etc. In Chinese teaching, you can insert pictures or videos related to the text content to help students better understand the context of the text; in English teaching, insert original English videos to improve students' listening and speaking skills. Teaching design combined with whiteboard function 1. Design interactive teaching sessions with the whiteboard according to the teaching content and objectives. For example, in history teaching, if you want to explain the development of historical events, you can use the timeline function of the whiteboard to arrange the events in chronological order on the timeline, so that students ca

Understand alignment in an digital whiteboard In an interactive whiteboard for classroom, the alignment feature is mainly used to arrange objects (such as text boxes, graphics, etc.) according to specific rules to make the content more neat, beautiful, and organized. Common alignment methods and how to do it. Horizontal alignment. Left:This can usually be done by selecting multiple objects that need to be aligned, and then selecting "Align Left" in the alignment tool options of the whiteboard software. This adjusts the left edge of the selected object to the same vertical line. For example, when displaying paragraph headings in multiple text boxes, use left-alignment to make the left side of the heading look uniform. Center Alignment (Horizontal):The procedure is similar to Align Left, select the object and click on the "Align Horizontally to Center" option. It causes the selected objects to be horizontally referenced to the center axis of the whiteboard, with the left and right sides equally apart. This is useful for example, when creating a symmetrical graphic combination or placing a title in the center of a whiteboard. Right Alignment:Similarly, use the Align Right tool with the object selected to align the right edge of the selected object to the same vertical line. When creating a table or presenting data, right-alignment can make the right edge of the data neat and easy to see and compare.

Here are the reasons why teachers use digital whiteboards. Enhance teaching interactivity. The interactive whiteboard for classroom allows teachers and students to touch directly on the surface of the whiteboard. For example, when teaching mathematical geometry, teachers can invite students to the stage and touch the whiteboard to drag the shape, change the shape and position of the shape, so that students can participate more actively in the class rather than passively listen to the lecture. This interactivity helps to improve students' attention and interest in learning, allowing them to better understand and grasp knowledge in the process of participation. Rich display of teaching resources. Teachers can use digital board for teachings to present multiple forms of teaching resources. It can be connected to computers, projectors and other devices to conveniently display PPT, video, audio, animation, etc. For example, in Chinese teaching, teachers can play a video related to the content of the text, such as an animated video made according to the artistic conception of the poem when explaining ancient poems, so that students can feel the scene depicted in the poem more intuitively. You can also display a variety of high-definition pictures, such as showing natural scenery, topography and landforms around the world in geography class, to help students better understand abstract concepts.

Principles and features of digital whiteboards The interactive whiteboard for classroom is a high-tech product that integrates electronic induction, display and computer technology. It uses technologies such as electromagnetic induction, infrared induction, or capacitive sensing to accurately capture the user's touch operation and transform the whiteboard surface into an interactive interface. Its core function is to be able to display images, videos, documents and other materials from the computer synchronously in real time, and support users to write, erase, zoom in, move and other operations directly on the whiteboard, so as to realize the deep interaction between people and information, greatly improve the effect of display and explanation, and are widely used in education, business meetings, training and other fields. Anatomy of the conditions for the reception of a television signal Watching TV requires a specific signal reception pathway. Traditional cable TV relies on coaxial cable to transmit RF signals, which requires the receiving equipment to have a corresponding RF interface for decoding the signal and restoring video and audio content; Satellite television involves a satellite signal receiving pot and specific decoding equipment to receive signals from satellite transmissions; Today's mainstream network TV is through network connection, using the streaming media protocol to receive TV program data from the server side, which requires the device to have a network connection function and sof

What are the disadvantages of digital whiteboards? Do you know? Then let me tell you. The price cost is higher. Smart board for teachings are inherently expensive, including the acquisition cost of hardware devices such as touch-sensitive screens, electronic components, etc. For some schools with limited budgets, small training institutions, or general corporate meeting rooms, it is a large expense. Moreover, if there is a failure in the process of use, the maintenance cost is also high, because its internal technology is more complex, requires professional repairs, and the replacement price of related parts is not low. Technical failures affect use. Electronic devices are prone to technical problems. For example, you may experience a software crash. If the software crashes during important occasions such as teaching and meetings, it will not only interrupt ongoing activities, but also lead to the loss of previous data, such as what is being written, files that are being displayed, etc. There are also problems with the hardware, such as the touch function not working. This can make it impossible for the teacher or presenter to operate the whiteboard properly, affecting the flow of teaching or presentation. In addition, connection problems are also common, such as unstable connection with the computer, resulting in interruption of screen transmission or blurred screens, splashing screens, etc.

Definition Digital whiteboard is a high-tech teaching and conference equipment that integrates computer technology, electronic sensing technology and projection display technology. It usually consists of whiteboard hardware and supporting software. From the appearance, it is similar to a traditional whiteboard, usually a large flat board, installed on the wall or bracket in classrooms, conference rooms and other places. Hardware composition Induction panel：This is one of the core components of the interactive electronic whiteboard. It is able to perceive touch, writing, and other operations in the outside world. Induction technology mainly includes electromagnetic induction, infrared induction, optical image induction, etc. For example, the electromagnetic induction whiteboard determines the position through the electromagnetic signal emitted by the electromagnetic pen, and when the electromagnetic pen is close to the whiteboard, the electromagnetic induction coil inside the whiteboard will detect the signal, so as to accurately locate the position of the pen tip, and realize high-precision writing and drawing functions. The infrared induction whiteboard uses the infrared emission and receiving tubes around the whiteboard, and when there is an object blocking the infrared light, the coordinates of the touch point are determined by calculating the interrupt position of the light.

Detailed dissection of infrared touch PCBA PCB, the full name is Printed Circuit Board Assembly, that is, printed circuit board assembly. This concept encompasses the transition from a basic printed circuit board (PCB) to a component that is ultimately fully circuitically functional. As a carrier, the PCB is a thin board composed of insulating materials and conductive wires stacked on top of each other, and according to the pre-designed circuit blueprint, fine conductive circuits are formed on the board through etching and other processes to build a "vein" for the connection of subsequent components. Once the PCB has been routed, the critical assembly stage begins. The first is the SMD process, with the help of high-precision SMD machines, the tiny dust-like surface mount components (SMDs), such as SMD resistors, SMD capacitors and various chips, are accurately placed to the specified pad position, which requires extremely high accuracy, and a slight deviation may cause circuit failure. This is followed by the plug-in process, in which some in-line components that are large and not suitable for the placement process, such as electrolytic capacitors and power transistors, are inserted into the corresponding jacks manually or through automated equipment. After the completion of component placement, and then through reflow soldering, wave soldering and other soldering techniques, the component pins and PCB pads are firmly integrated, so far, a complete PCBA was born, which integrates a large number of electronic components with different functions, can achieve specific circuit functions, and is the core "internal organs" of many electronic products.

1.Infrared touch PCBA ’ s summarize PCB is an abbreviation for Printed Circuit Board Assembly. It refers to the printed circuit board that has completed the assembly of components, and is the core component of electronic products. 2.Analysis of PCBAs PCBA analysis is the process of inspecting, evaluating, and troubleshooting printed circuit board components. The purpose is to ensure that the quality and performance of the PCBA meets the design requirements, and that possible problems and defects can be identified. 3.The main content of PCBA analysis Appearance inspection This is the most basic step of analysis.

1.Definition of infrared touch PCBA Services PCB is an abbreviation for Printed Circuit Board Assembly. PCBA service refers to a series of complete electronic manufacturing services from the component procurement, placement, insertion, and soldering of printed circuit boards (PCB) to the testing and debugging of circuit boards. 2.The specifics of PCBA services Component procurement:This is the foundation of PCBA services. Service providers need to purchase various electronic components, such as chips, resistors, capacitors, inductors, etc., from reliable suppliers according to the design requirements. In the procurement process, the quality of components should be strictly controlled to ensure that they meet the performance standards of the product, such as checking the specifications of the components, brand reputation, whether they are genuine and many other factors. SMT chip processing:Surface mount technology (SMT) is a key process in PCBA services. It is the precise mounting of surface mount components to the specified location on the PCB board. This process requires high-precision placement machine equipment that can pick and place tiny components quickly and precisely. When mounting, it is necessary to consider the pack

  Here are the details on how to inspect infrared touch PCBA (Printed Circuit Board Assemblies): Outward appearance inspection 1. Component Integrity: First of all, observe whether all kinds of components on the PCB are complete, and whether there are any omissions or wrong pastes. For example, resistors, capacitors, chips, etc., are checked against the schematic and bill of materials (BOM) to ensure that the correct components are in place at each location. Check the pins of the components to see if there is any deformation and breakage, and for the chip components, the pins should be soldered flat on the pads. 2. Welding quality: Look at the appearance of the solder joints, high-quality solder joints should be smooth, rounded, and bright silver or golden yellow. There should be no defects such as porosity, cracks, and virtual welding on the surface. Virtual soldering is manifested as a solder joint that looks like a connection but the actual contact is poor, gently shaking the component, if the solder joint shows signs of loosening, it may be a virtual solder. Check the amount of solder, which can not cause too much short circuit of adjacent solder joints, nor too little to affect the reliability of electrical connections. Bridging is also a common problem, i.e. there should be no extra solder connections between adjacent solder joints.

Conception A infrared PCBA coating is a protective material that covers the surface of a printed circuit board assembly (PCB). It is through a specific coating process to evenly apply the coating to the circuits, components and other parts of the PCBA to play a protective role. Main features Protection:It can effectively isolate moisture, dust and chemicals from the outside world. For example, in a humid environment, prevent water vapor from contacting the circuit board and causing a short circuit; In situations where there is a risk of chemical corrosion, avoid damage to the PCBA caused by corrosive gases or liquids. Insulation properties:Enhance the insulation of PCBAs, reduce the risk of failure due to accidental conduction between electrical components, especially in high-voltage operating environments, and ensure the safety and stability of circuits. Improved stability:Provides physical protection for electronic components and mitigates the impact of mechanical factors such as vibration and collision on components and wiring connections, thereby extending the life of PCBAs.

Definition of Infrared PCBA controller PCB (Printed Circuit Board Assembly) is a printed circuit board assembly. A PCBA controller is a control unit built on the basis of a printed circuit board assembly. It mainly implements specific control functions through the layout and connection of various electronic components (such as chips, capacitors, resistors, etc.) in the circuit. For example, in automation equipment, the PCBA controller can control the speed and direction of the motor, or monitor the data of the sensor, and accurately control the operation of the entire equipment according to preset programs and algorithms. The composition of the PCBA controller Chip (microcontroller or microprocessor):This is the core part of the PCBA controller, and it's like the human brain. Pre-written program instructions are stored inside the chip, which are executed to control and process data for external devices. For example, a PCBA controller chip in a smart home system can control the switching and temperature regulation of an air conditioner based on the received temperature sensor data. Power Circuit:Provide a stable power supply for the entire PCBA controller. Power circuits are capable of converting external input voltages, such as mains or battery voltages, into the operating voltages required by chips and other electronic components. For example, convert 220V

Here are some of the materials that apply to capacitive touch screen monitors: 1.Human and animal conductors Human skin:The human body itself is a good conductor with a certain charge. When the finger touches the capacitive touch display, a coupling capacitor is formed between the finger and the capacitive sensor on the surface of the touch screen, and this change in capacitance can be detected by the control circuit of the touch screen, so as to realize touch positioning and operation. Animal Hair & Skin:Some specially designed capacitive touch screen overlay devices can also be touched through animal hair or skin. However, animal hair is often less conductive and requires a device with high sensitivity. 2.A stylus made of conductive material Metal Stylus:Metals have good electrical conductivity, and stylus made of materials such as copper and aluminum can be used on capacitive touch screens. When the metal stylus touches the screen, it is able to conduct an electrical charge, causing a change in the capacitance of the touch screen, which is recognized by the screen just like a finger touch. Conductive rubber stylus:It is usually made of conductive fibers, such as carbon fiber, on the nib or nib part of the pen. These fibers conduct an electrical charge that allows the stylus to generate a touch signal on a capacitive touchscreen, while the body can be made of other materials to provide a comfortable grip. 3.Spec

1.Most laptops touch screen type Nowadays, the vast majority of laptops are equipped with capacitive touch screen monitors. The capacitive touch display mainly uses the principle of capacitive sensing to operate, and it is equipped with a capacitive sensing array. The conductive coating on the surface of the screen forms a capacitive coupling with the human body, and when the finger touches the screen, the capacitance value of the touch point is changed, and the touch chip can accurately locate the touch position according to the capacitance change to achieve accurate interaction. Like Apple's MacBook Pro with Touch Bar version and the touchscreen of some models in the Dell XPS series, they are typical capacitive touchscreens, and the controls are smooth and smooth, whether you zoom in or out of an image, swipe a page, or tap on an icon, it can respond quickly and bring users a convenient experience. 2.The advantages of capacitive touch screen overlays determine their mainstream status. The reason why capacitive touch screens have become the mainstream choice of laptop touch screens is due to many advantages. First, it has high sensitivity, and the slightest touch of the finger can be accurately captured, which greatly improves the operation efficiency, such as when quickly entering text, it can achieve almost real-time feedback, reducing the probability of false touches; Second, it supports multi-touch operation, users can zoom in with two fingers, switch programs with three fingers, etc., to facilitate complex gesture operations, whi
