Q:When I tested the screen with resistive screen, I found that the water ripple appeared on the ampoule touch screen. Could you tell me why?
A: there are two main aspects of the water ripple in the resistive screen:
1.The gap between the resistive screen and the LCD is not enough when the LCD is designed and assembled. 2. When assembling the machine case and the screen, the structure is too tight, and there are objects on the back of the screen to support it, forming the principle of carrying rod.Test method: put the screen on the flat desktop, light the screen and touch the surface to see if there are water ripples. If not, it is likely to be caused by the assembly of the chassis and the screen.
