High brightness LCD displays achieve multi-touch mainly by adding special touch technology to the display. The most common is capacitive touch technology. There is a transparent conductive layer on the display surface. When a finger touches the display, the capacitance value will change. The system determines the touch position and action by detecting these capacitance changes. In this way, multi-touch can be achieved, allowing us to operate with multiple fingers at the same time.

In addition to capacitive touch technology, what other technologies can achieve multi-touch on high brightness LCD display?

1. Resistive touch technology: This display consists of two conductive layers separated by an insulating layer. When a finger presses the display, the two conductive layers come into contact, changing the resistance value, and the touch position is determined by detecting the resistance change. It can achieve multi-touch, but the accuracy is relatively low, and it is easy to wear after long-term use.

2. Infrared touch technology: Infrared transmitting tubes and receiving tubes are installed on the display frame to form an infrared matrix. When a finger blocks the infrared, the receiving tube detects the signal change and determines the touch position. This technology can achieve multi-touch, is not affected by external electromagnetic interference, and has a fast response speed, but may be affected under strong light, and has certain requirements for the touch object.

3. Optical touch technology: By installing cameras and light sources around the display, when a finger touches the display, the light reflection change is captured by the camera, and the touch position is determined using image recognition technology. It can achieve high precision multi-touch and has strong adaptability to ambient light, but it has high cost and complex structure.
