Abstract

The invention relates to an in-cell touch liquid crystal display panel and an in-cell touch liquid crystal display module. The in-cell touch liquid crystal display panel includes a color filter substrate, a thin film transistor (TFT) substrate which is arranged opposite to the color filter substrate, a liquid crystal layer between the color filter substrate and the TFT substrate, and a sensing electrode layer, wherein the sensing electrode layer includes touch electrodes and pressure sensing electrodes being arranged in the same layer; the touch electrodes are used for detecting the touch motion applied to the in-cell touch liquid crystal display panel; and the pressure sensing electrodes are used for sensing the pressure of the touch motion.

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...
