Capacitive Touch Screen Panel VS TFT LCD Screen


Published by JFCVision October 16,2019

A capacitive touch panel is not a real display screen, but a component that is mounted above the LCD screen. The capacitive touch panel is a transparent tempered glass in appearance.


Furthermore, the two cannot be compared horizontally because they are not parts of the same kind. Most touch monitors have both screens.


A capacitive touch panel is a touch panel that is transparent like glass and does not display anything or emit light. The capacitive touch panel function is to sense the user's touch operation.

The TFT screen is the real display screen. TFT is the most widely used liquid crystal display material. The TFT LCD screen is a thin film transistor liquid crystal screen, which is a display screen, and has no function of sensing touch, and can only be used to display an image.

In the current display screen, two types of screens, a capacitive touch panel, and a TFT LCD panel, are usually used at the same time, and the two are vertically overlapped, and the TFT LCD panel is responsible for displaying images, and the capacitive touch screen is responsible for sensing user operations. It is the origin of "internal screen" and "outer screen".
