Capacitive Touch Screen

TFT LCD Capacitive Touchscreen

Maclight provide difference TFT LCD capacitive touch screen and OLED touch screen solution, the tft lcd capacitive touch screen could be achieved the multi touch function via CTP touch screen, unlike resistive touch screen, capacitive touch is working on an touch sensor and can handle multi touch points, projected capacitive touch is very popular touch screen on tft lcd application, we could use capacitive touchscreens by bare finger. Capacitive ouch screens are a type of overlay placed on a display screen used to register touch interaction on the tft lcd screen. Capacitive touch screen are not a type of display, but it is a component that can be added to an existing tft lcd screen or OLED screen.

What are the connecton types available for capacitive touch and lcd screen?

The connection ways have optical bonding and air-gap bonding. the optical bonding is the OCA gule between capacitive touch and LCD screen, OCA glue could reduce the refraction to lcd screen and capacitive touch screen, it bring clearer display performance than air-gap bonding. while air gap bonding means there is air between the gap of capacitive touch panel and lcd screen, there is light refraction on the air gap, and lead to light scattering for the capacitive touch screen.
