The use of characteristics is good, the touch does not require force, and there is no special requirement for the touch body.
Regardless of whether the touched object is hard or conductive, it will not affect normal use
Infrared touch screen principle:
Generally, an outer frame is installed in front of the monitor screen, and there is a circuit board in the outer frame.
There are infrared emitting tubes and infrared receiving tubes evenly arranged in the X and Y directions,
one-to-one correspondence to form a horizontal and vertical cross infrared matrix.
When there is a touch, fingers or other objects will block the horizontal and vertical infrared rays passing through the point,
The controller determines the position of the touch point on the screen
