how touch screen display works.This part of the circuit mainly includes driving infrared transmitting part , driving infrared receiving part, exit communication part, JTAG debugging part. Drives the infrared-emitting portion of the chip by 4 feet, of 44 feet, the first 48 feet to complete, respectively, for controlling the braking state of the infrared emission of the light-dark signal : the DS ,SH - the CP , ST - the CP. Circuit principle reason as shown below:
