1.Differences in how it works
Conductive touch screen
- Conductive touch screen mainly uses pressure sensing to work. Its screen structure is generally multi-layered, with tiny gaps between two conductive layers. When an object, such as a finger, presses against the screen, the two conductive layers come into contact under pressure, allowing an electric current to pass through the contact point. The location of the touch is determined by detecting changes in the current. The touchscreen is like a pressure switch, and the contact generated by pressing is the key to triggering the operation.
Capacitive Touch Screen monitor
- Capacitive touch display is to use the current induction of the human body to work. The surface of the capacitive screen has a layer of transparent conductive material, and when the finger touches the screen, due to the static electricity of the human body itself, the finger and the surface of the screen form a coupling capacitance. Because the change in capacitance causes the circuit under the screen to detect changes in electrical signals, the position of the touch point is determined by calculating the position of these electrical signal changes. It's as if the screen is able to sense the faint changes in the electric field brought about by the human body, and the Capacitive touch screen panel can support multiple touches, which is an important advantage.
2.The touch experience is different
Conductive touch screen
- Since it is triggered by pressure, a certain degree of pressure is required to make the conductive layer contact respond. This may make the user feel "hard" when operating, and after long-term use, if the elastic layer of the touchscreen deteriorates, etc., it may affect the sensitivity of the touch, resulting in more pressure to operate.
Capacitive touch screen
- Capacitive touch screen is very responsive to touch. Because it works by sensing changes in the electric field, it can be detected by a slight touch or even close to the screen. When using devices with capacitive touch screens, such as smartphones, users can perform a variety of operations with just a tap and swipe, making the touch experience smoother and more natural. Moreover, the capacitive touch screen supports multi-touch, and users can use multiple fingers to zoom and rotate at the same time, which greatly enriches the way users interact with the device.
3.Durability and maintenance aspects
Conductive touch screen
- Conductive touch screen is relatively durable, because its structure is relatively simple, and structures such as multi-layer conductive layers and isolation layers can withstand a certain degree of physical stress and wear. However, if the surface of the screen is scratched by a sharp object, it may affect the contact of the conductive layer, resulting in abnormal touch.
Capacitive touch screen
- Capacitive touch screen surfaces may briefly malfunction if they are subjected to static interference. Moreover, if there are conductive substances such as oil stains and water stains on the surface, it may also interfere with the normal sensing of the capacitance, resulting in inaccurate touch. However, in the normal use environment, as long as attention is paid to avoid these interference factors, the durability of the capacitive touch screen can still meet the needs of daily use. And with the development of technology, the anti-interference ability of capacitive touch screen is also improving.
4.Precision and accuracy
Conductive touch screen
- The accuracy of the conductive touch screen depends mainly on the quality of the conductive layer and the uniformity of the pressure sensing. Theoretically, its accuracy can reach a certain level, but due to the pressure contact, inaccurate positioning may occur when the pressure is uneven at the edges or in the part of the screen.
Capacitive touch screen
- Capacitive touch screen has high accuracy because it determines the touch position by sensing changes in the electric field, and it is able to accurately calculate the position of each touch point. The advantages of capacitive touchscreens are especially evident when performing delicate operations, such as drawing details in drawing software or tapping small icons on mobile phones. Moreover, the multi-touch accuracy of the capacitive touch screen can also meet the needs of complex operations such as games, and the position and movement between multiple touch points can be accurately recognized.
