Abstract

The invention is suitable for the technical field of touch display, and provides a touch display device. The touch display device comprises a first substrate and a TFT (Thin Film Transistor) array, wherein the TFT array is arranged on the first substrate and at least comprises multiple gate electrodes and multiple source electrodes, the first substrate is also provided with multiple first electrode wires which are connected with the gate electrodes, the first electrode wires double as display driving electrodes and touch driving electrodes, and time-sharing loading of display driving signals and touch control driving signals is realized in a period of every frame . According to the touch display device provided by the invention, the functions of display driving and touch driving are simultaneously obtained by the first electrodes, and the process of manufacturing passages does not need to be added; the voltage of second electrodes and a common electrode are not influenced, so that driving signals of the second electrodes also do not need to be transformed, the developing difficulty of a display driving program can be reduced, and the cost is also reduced.

Description

technical field [0001] The invention belongs to the technical field of touch display, and in particular relates to a touch display device. Background technique [0002] The touch electrode embedded (Incell) touch display panel uses the touch electrode in the LCD pixel. Compared with the integrated capacitive touch screen (OGS), the strength is higher and the whole opportunity is thinner, so it will become the future mainstream technology. In the traditional Incell touch display panel, the touch scanning electrodes are shared with the common electrodes (com electrodes) of the LCD, but because the touch electrodes need to be made into a channel structure, it is necessary to add a process of making the com electrodes into a channel structure, and the cost Increase; and the touch scan and LCD driver share the com voltage, so the com voltage will change when the touch is touched, such as figure 1 , and LCD mainly controls the display through the difference between the com volta...
