specktron udx-86 interactive touch led screen.l Theinfrared touch screen works with multiple pairs of infrared transmitting and receiving tubes. The performance and life of the infrared tube 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 the periphery This requires that the sensor not only has good performance, but also requires that the "light-resistance characteristics" and "junction capacitance" of nearly 100 pairs of infrared diodes be consistent. In actual application, if any pair fails, it can be found during the power-on self-test and ignored afterwards. It is replaced by adjacent infrared rays. Since each pair of infrared rays only "supervises" a narrow band of about 6mm, The thickness of a finger is usually around 15mm, which is imperceptible to the user.
