How does the multitouch screen work
- Oct 29, 2018 -


How does the multitouch screen work?The infrared multitouch screen USES the infrared matrix in X and Y direction to detect the touch action of the operator.The infrared multitouch screen needs to install a circuit board outer frame in the front of the display. The circuit board is arranged on the four sides of the screen with the infrared transmitting tube and the infrared receiving tube one by one to form the infrared matrix of cross and cross.When the user touches the screen, his or her finger blocks two infrared rays that pass through it, thus determining where the touch point is on the screen.Any non - transparent object can change the infrared on the contact and realize the multi-touch screen operation.
