Problems solved by technology

Since the touch display panel adopts a concave design, the length of the first scanning line 811 is smaller than the length of the second scanning line 821, so that the resistance and capacitance of the first scanning line 811 are smaller than the resistance of the second scanning line 821. value and capacitance value, so that the capacitive load of the first scan line 811 is smaller than the capacitive load of the second scan line 821, so that when the touch display panel displays, the capacitive load of the first scan line 811 is smaller than that of the second scan line 821. The capacitive load of the scan line 821 causes display chromatic aberration

Embodiment Construction

[0047] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0048] see Figure 3 to Figure 5 , the first embodiment of the touch display panel of the present invention adopts a concave design, including a touch layer 100 and a chip 200 . The touch layer 100 includes a common electrode layer 110 and a wiring layer 120 opposite to the common electrode layer 110 . The chip 200 is disposed outside the common electrode layer 110 . The common electrode layer 110 includes a first sub-electrode layer 111, a second sub-electrode layer 112 disposed at one end of the first sub-electrode layer 111, disposed at an end of the second sub-electrode layer 112 away from the first sub-electrode layer 111 and spaced apart from each other. two third sub-electrode layers 113. The second sub-electrode layer 112 and the tw...

Abstract

The invention provides a touch control display panel. The touch control display panel adopts inwards-sunken design. The sum of the contact resistance of touch control electrodes and corresponding routing wires and the resistance of the corresponding routing wires is defined as the corresponding first resistance of the touch control electrodes, the corresponding first resistance of the touch control electrodes with the same area is equal, in the touch control electrode with different areas, the corresponding first resistance of the small-area touch control electrodes is larger than the corresponding first resistance of the large-area touch control electrode, thus the resistance loads between the touch control electrodes with the different areas are consistent, and the difference of the display and touch control effects due to the fact that the touch control display panel adopts the inwards-sunken design, and thus the areas of all the touch control electrodes are different can be eliminated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel. Background technique [0002] In the field of display technology, flat panel display devices such as liquid crystal display devices (Liquid Crystal Display, LCD) have gradually replaced cathode ray tube (Cathode Ray Tube, CRT) display devices. The liquid crystal display device has many advantages such as a thin body, power saving, and no radiation, and has been widely used. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Generally, a liquid crystal display panel consists of a color filter (Color Filter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) array substrate, a liquid crystal (Liquid Crystal, LC) and a sealant sandwiched between the color filter substrate and the thin film transist...
