touchscreen.The infrared touch screen works with multiple pairs of infrared transmitting and receiving tubes. The performance and life of the infrared pair are reliable. Any object that blocks light can be used as a touch object. However, the infrared touch screen uses nearly 100 sensors and shares peripheral circuits This requires that not only the performance of the sensor is good, but also the "light - resistance characteristics" of nearly 100 pairs of infrared diodes .
