Problems solved by technology

However, in the above two structures, the touch electric field between the driving electrode 500' and the sensing electrode 400' must pass through the liquid crystal layer 300', and the deflection of the liquid crystal molecules in the liquid crystal layer is determined by the display between the pixel electrode and the common electrode. Electric field control, resulting in the interaction between the touch electric field and the display electric field

Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] figure 2 It is a schematic diagram of a color filter substrate provided in an embodiment of the present invention, the color filter substrate includes a base substrate 101, and a black matrix layer 102 and a color filter layer 103 arranged on the base substrate, wherein the substrate A first touch electrode 400 and a second touch electrode 500 for forming a touch electric field are also disposed on the substrate 101 .

[0029] Specifically, the first touch electrode 400 and the second touch electrode 500 may be disposed on the color filter layer 103 , and an insulating layer 600 is further formed between the first touch electrode 400 and the second touch electrode...

Abstract

The invention provides a color filter substrate and a display device. The color filter substrate includes a base substrate, and a black matrix layer and a color filter layer arranged on the base substrate. The first touch electrode and the second touch electrode of the touch electric field. In the color filter substrate provided by the present invention, both the first touch electrode and the second touch electrode are formed on the color filter substrate, so that the touch electric field generated by the first touch electrode and the second touch electrode is far away from the liquid crystal layer, Therefore, the interaction between the touch electric field and the display electric field is reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a color filter substrate and a display device. Background technique [0002] With the rapid development of display technology, touch screens have gradually spread in people's lives. At present, touch screens can be divided into three types according to their composition structures: external touch screens, surface-covering touch screens, and built-in touch screens. Among them, the embedded touch screen embeds the touch electrodes of the touch screen inside the liquid crystal display, which can reduce the overall thickness of the module and greatly reduce the production cost of the touch screen, and is favored by major panel manufacturers. [0003] The traditional embedded touch screen includes two schemes, the structure of the first scheme is as follows figure 1 As shown, the driving electrode 500' is arranged on the side of the array substrate 200' (TFT substrate), and the sensing electrode...
