What Are the Differences Between Capacitive Touch Screen and TFT Touch Screen Display?

1. Introduction to TFT touch screen display

TFT touch screen display set a semiconductor switch for each pixel, and each pixel can be directly controlled by point pulse. Therefore, each node is relatively independent and can be controlled continuously. It can not only improve the response speed of TFT touch screen display, but also accurately control the display color level of the TFT touch panel. Therefore, the color of TFT touch screen display is more true. TFT display touch screen has excellent color saturation, restore ability and higher contrast.

2. Difference between capacitive touch screen and TFT touch screen display

Capacitive touch screen is not a real screen, but a component, which is installed on the top of the LCD screen. The capacitor screen is a transparent tempered glass in appearance. Moreover, the two can not be compared horizontally, because they are not the same kind of parts. Most mobile phones have both screens. Capacitive touch screen is a kind of touch screen. TFT capacitive is as transparent as glass, which will not display anything and will not glow. The function of TFT capacitive touch screen is to sense the user's touch operation.

TFT touch screen display is the real screen. TFT is the most widely used liquid crystal display material, which is mainly used in the low-end display field, and more used in mobile phones. TFT touch screen display is a thin film transistor liquid crystal screen, a kind of display. At present, mobile phones usually use these two screens at the same time. The two are overlapped up and down, and the TFT touch screen display is used to display the image. The capacitive touch screen is used to sense user operation, which is the origin of "internal screen" and "external screen".
