The disadvantage is that the outer film of the resistive touch screen is easily scratched and the touch screen is not available. The multi-layer structure will cause great light loss. For handheld devices, it is usually necessary to increase the backlight to compensate for the poor light transmission, but this also Will increase the battery consumption.
The disadvantages of resistive touch screens can be categorized as:
1. The resistive touch screen can be designed to be multi-touch, but when the two points are pressed at the same time, the pressure of the screen becomes unbalanced, resulting in errors in the touch, and thus the degree of multi-touch is difficult to achieve.
2. Resistive touch screens are susceptible to scratches on the touch screen.
