Touch experience to a new level

Indoor LED display

At present, infrared touch screens are sharing the touch screen market with resistive touch screens and capacitive touch screens. Although touch screens appear late, they are developing rapidly. We can understand the working principle of infrared touch screen.

1. The relevant equipment preparation before the work of the infrared touch screen. The infrared touch screen in the black gold industry has an infrared matrix set close to the screen, which can detect and locate the user's touch. The touch screen is equipped with an outer frame in front of the display, and the frame involves the circuit board, which can form an infrared matrix through one-to-one correspondence.

2. Touch the reaction under work. When touching, a finger or other foreign object blocks the infrared rays at the location. When scanning, when infrared rays are found to be blocked, the light on the x-axis indicates that the infrared sensor is blocked, and the light on the Y-axis indicates that there is a touch. Therefore, it is concluded that the X and Y two-axis lights are on at the same time, which means that the touch is found and confirmed.

Because the black gold touch screen can be accurately calculated and positioned, the accuracy rate is very high. These advantages, coupled with continuous research and development in this area, gradually occupy the touch screen market.
