Problems solved by technology

[0004] However, in the above-mentioned existing capacitive embedded touch screen, the mutual capacitance generated between the touch sensing line and the touch driving line is small, so that the electric field of the human body has little influence on the change of the mutual capacitance. When the human body touches the touch screen, the touch The change of the power signal coupled out by the control sensing electrode is small, making the sensing sensitivity of the touch screen low

Embodiment Construction

[0031] The specific implementation manners of the in-cell touch screen and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] The film thickness and shape of each layer in the drawings do not reflect the true proportion of the in-cell touch screen, but are only intended to schematically illustrate the content of the present invention.

[0033] An embedded touch screen provided by an embodiment of the present invention, such as Figure 2 to Figure 7 As shown, it includes the opposite array substrate 1 and the opposite substrate ( Figure 2 to Figure 7 not shown in ), the common electrode layer 01 located on the side of the opposite substrate facing the array substrate 1 or the side of the array substrate 1 facing the opposite substrate; The first strip electrode 11 and the second strip electrode 12, and during the touch time period:

[0034] Such as figure 2 As shown...

Abstract

The invention discloses an in-cell touch screen and a display device. The in-cell touch screen comprises first touch electrodes and second touch electrodes which are arranged in a staggered mode, the second touch electrodes are composed of first sub-electrodes and second sub-electrodes which are connected end to end in the first direction in an alternate mode, the first sub-electrodes extend in the first direction, the second sub-electrodes extend in the direction perpendicular to the first direction, and orthographic projection of the second sub-electrodes on an array substrate is located on the orthographic projection of the first touch electrodes on the array substrate. Compared with an existing in-cell touch screen, the second touch electrodes are made to be set as fold lines, relative areas between the first touch electrodes and the second touch electrodes can be increased, mutual capacitance between the first touch electrodes and the second touch electrodes in unit area is increased, and therefore the sensitivity of the in-cell touch screen during touching is improved.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to an embedded touch screen and a display device. Background technique [0002] With the rapid development of display technology, touch screens (TouchScreenPanel) have gradually spread in people's lives. At present, touch screens can be divided into three types according to their composition structures: Add-on Mode Touch Panel, OnCell Touch Panel, and InCell Touch Panel. Among them, the plug-in touch screen is produced separately from the touch screen and the Liquid Crystal Display (LCD), and then bonded together to form a liquid crystal display with touch function. The plug-in touch screen has high production costs, low light transmittance, The module is thicker and other shortcomings. 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 produc...
