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 insulated from each other and arrayed in a cross mode, each touch drive electrode comprises a plurality of touch drive sub-electrodes, each touch drive sub-electrode is located between two corresponding adjacent public electrodes; each public electrode comprises a plurality of public sub-electrodes; touch sensing electrodes are arranged on opposite substrates, the projection of each touch sensing electrode in the array substrate is located in an area where the public electrodes are located, 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 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 ...
