Using an infrared touch screen in an environment with sunlight will be greatly disturbed, which will cause malfunction when the light changes greatly. In order to enhance the anti-light interference performance of the infrared touch screen, two methods are mainly used in the existing technology : one is to modify and adjust the circuit ; the other is to prevent or let outside light shine on the infrared tube. , That is, physical light protection . Here are some scenarios:
