The disadvantage of this method is that the detection device must be larger than the display screen or the same size as the screen, which affects the light transmittance of the screen and is not conducive to the system that only touches a small area.

Integral touch display device is to make the touch detection device on the display screen of the display device when manufacturing the display device, so that the display screen of the display device directly has touch function, which is the integral touch screen. This method is to directly mount the touch monitoring device on the front of the display or make it on the front glass of the display. It is directly produced by the display manufacturer. Generally, the entire screen is touched, which is not conducive to the system that only touches a small area. , will affect the light transmittance, and is also not conducive to the customized functions and cost control of display equipment manufacturers.
