Abstract

The application discloses an integrated touch display device. The display device comprises a display panel and a backlight module, wherein the display panel comprises a first substrate and a second substrate which are opposite to each other, one of the first substrate and the second substrate is provided with strip-shaped touch emission electrodes arranged in parallel, and the other of the first substrate and the second substrate is provided with strip-shaped touch receiving electrodes arranged in parallel; the extension directions of the strip-shaped touch emission electrode and the strip-shaped receiving electrode are intersected; the strip-shaped touch emission electrode or the strip-shaped receiving electrode is multiplexed as a first pressure electrode; the backlight module comprises a second pressure electrode; a gap is formed between the display panel and the backlight module; the first pressure electrode, the second pressure electrode and the gap form a pressure capacitor; the pressure capacitor is used for sensing the pressure exerted on the integrated touch display device. The integrated touch display device is capable of realizing pressure detection function, and capable of simplifying the manufacture process and reducing the cost.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of touch display technology, and in particular to an integrated touch display device. Background technique [0002] With the development of the touch display technology, the pressure detection of the touch display screen has more and more extensive applications. In the existing touch screen design with pressure detection function, an external pressure sensing electrode is usually set outside the glass membrane group, and the pressure sensing electrode is set in the middle frame module. The electrodes and the pressure-sensing electrodes attached to the glass membrane group are used as the two plates of the piezo-sensitive capacitance to sense pressure changes. The design of the pressure-sensitive capacitor in this design depends on the design of the middle frame module, and the pressure sensing electrode needs to be fabricated in the process of the middle fra...
