Basic concepts

IPS:IPS stands for In-Plane Switching technology, which is a liquid crystal display technology. It improves viewing angles and color representation by changing the arrangement of liquid crystal molecules. The liquid crystal molecules rotate in a plane parallel to the screen, so that the light can be transmitted more evenly from all angles, and the display effect of a wide viewing angle can be realized. For example, when multiple people are looking at a monitor at the same time or using a tablet, an IPS screen ensures that viewers from all angles can see a clear, color-accurate picture.

Capacitive Touch Screen overlay:A capacitive touch display is a touch screen based on the principle of capacitive sensing. It covers the surface of the screen with a transparent layer of conductive material that changes the capacitance at the touch point when a conductive object, such as a finger, touches the screen. By detecting the location and extent of capacitance change, the device can determine the position and action of the touch. It's like a sensitive electric field sensor, where the touch of a finger triggers a small change in the electric field, which is then recognized by the device.

Differences in functional features

1. Display quality aspect

IPS:With excellent color accuracy and saturation. Because its liquid crystal molecular arrangement is conducive to the accurate presentation of colors, it can display rich and true colors, and has good support for professional image, video editing and other work. Moreover, the viewing angle is large, and the viewing range can almost reach 178 degrees, and the picture quality does not deteriorate significantly when viewed from different angles.

The response time is relatively fast, and it can effectively reduce ghosting when displaying dynamic images, making moving pictures smoother, such as when playing high dynamic range videos or switching between high-speed games.

Capacitive touch screen monitor:High touch accuracy, able to accurately locate the position of finger touch, the smallest recognizable touch area is small, can meet the needs of fine operations such as clicking small icons on the mobile phone screen, selecting text, etc.

2. Touch operation aspect

IPS:There is no touch function per se, just a display technology. However, when combined with touch technology, it acts as a display carrier to provide visual feedback for touch operation.

Capacitive touch screen:High touch accuracy, able to accurately locate the position of finger touch, the smallest recognizable touch area is small, can meet the needs of fine operations such as clicking small icons on the mobile phone screen, selecting text, etc.

It supports multi-touch, and users can use multiple fingers to operate at the same time, such as using two fingers to zoom in and out of pictures on the phone, and three fingers to switch between applications.

Differences in application scenarios

IPS:It is mainly used in devices with high display requirements, such as high-end monitors, professional drawing equipment, high-end tablets and laptops, etc. In these devices, IPS screens can take full advantage of their accurate display colors and wide viewing angles to provide users with a high-quality visual experience, such as designers can accurately grasp color and detail on IPS-screen drawing devices.

Capacitive touch screen:It is widely used in various mobile devices and smart terminals that require touch operation, such as smart phones, smart watches, smart speakers and other devices with touch interaction functions. It allows users to conveniently operate the device with simple touch gestures for various functions, such as making calls and sending messages through the touch screen.
