Abstract

An in-cell touch display apparatus includes a color filter structure, a thin film transistor (TFT) array structure, a liquid crystal layer between the color filter structure and the TFT array structure, and a driving and detection unit. The color filter structure comprises a touch electrode layer. The TFT array structure comprises a conductive layer. The touch electrode layer comprises a plurality of touch electrodes arranged in a matrix and a plurality of pressure sensing electrodes arranged in a matrix. The touch electrodes and the pressure sensing electrodes are located on a same layer. The conductive layer comprises a plurality of conductive portions. The touch electrodes sense a touch position, and the pressure sensing electrodes and the conductive portions cooperate with each other to sense a touch pressure.

Description

technical field [0001] The invention relates to an embedded touch liquid crystal display panel and an embedded touch liquid crystal display module. Background technique [0002] A liquid crystal display panel usually includes two opposite substrates, a liquid crystal layer sandwiched between the two substrates, and a sensing electrode layer sandwiched between the two substrates, wherein the sensing electrode layer is used for sensing the applied to the touch action of the embedded touch liquid crystal display panel. Furthermore, pressure sensing technology refers to a technology that can detect external forces. This technology has been used in industrial control, medical and other fields a long time ago. At present, the way to achieve pressure sensing in the display field, especially in the field of mobile phones or tablets, is to add an additional mechanism to the backlight part of the LCD panel or the middle frame of the mobile phone. This design requires structural desig...
