smart board 2075 display sbd-2075.In the past, the resolution of infrared touch screens was determined by the number of infrared pairs in the frame. Therefore, the resolution is low. The main domestic products on the market are 32x32 and 40X32. In addition, it is said that infrared screens are more sensitive to lighting environmental factors, In the old age, it will be misjudged or even crashed. These are the weaknesses of infrared screens sold by domestic non-IR touch screen domestic agents. The resolution of the latest generation of the fifth-generation infrared screen depends on the number of infrared pairs, scanning frequency and difference algorithm. The resolution has reached 1000X720. As for the infrared screen, it is unstable under light conditions. From the second-generation infrared touch screen, From the beginning, the weakness of anti-light interference has been overcome.
