Embodiment Construction

[0030] 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.

[0031] The thickness and shape of each film layer in the drawings do not reflect the real scale, and the purpose is only to illustrate the content of the present invention.

[0032] figure 2 A schematic cross-sectional view of an in-cell touch screen provided by an embodiment of the present invention. An embedded touch screen provided by an embodiment of the present invention, such as figure 2 As shown, an array substrate 100 having a common electrode layer 110, and an opposite substrate 200 opposite to the array substrate 100;

[0033] Such as Figure 3a or Figure 3b As shown, the common electrode layer 110 of the array substrate 100 is composed of a plurality of touch driving sub-electrodes 111 and a plurality of common sub-electrodes 112 arrange...

Abstract

The invention discloses an embedded type touch screen and a display device. A public electrode layer integrally connected in an array substrate is divided to form a plurality of touch drive sub-electrodes and a plurality of public sub-electrodes, the touch drive sub-electrodes and the public sub-electrodes are independent of each other and arrayed at intervals, the touch drive sub-electrodes are electrically connected through touch drive signal lines to form touch drive electrodes, and the public sub-electrodes are electrically connected through public electrode signal lines to form public electrodes; touch sensing electrodes are arranged on opposite substrates, the touch sensing electrodes and the touch drive electrodes are arranged in a cross mode, the touch drive electrodes are driven in a time-share mode, and therefore the touch function and the display function are achieved. Due to the fact that the touch drive electrodes in the touch screen are composed of the multiple touch drive sub-electrodes and the public electrodes are composed of the multiple public sub-electrodes, the signal transmission loads of the touch drive electrodes and the public electrodes are relatively close, the transmission speed of public signals in the public electrodes in the display stage and the transmission speed of public signals in the touch drive electrodes in the display stage are also relatively close, the problem that displayed images are not even can be solved, and image quality can be improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to an embedded touch screen and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread throughout people's lives. At present, touch screens can be divided into three types according to their structure: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel. Among them, the plug-in touch screen is produced separately from the touch screen and Liquid Crystal Display (LCD), and then bonded together to form a touch-enabled LCD screen. The plug-in touch screen has high production costs and low light transmittance. Low, thick modules 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 production cost of the touch ...
