Abstract

The embodiment of the invention relates to a touch screen, a display device and a driving method of the touch screen. The touch screen comprises an array substrate with a public electrode layer which is divided into multiple arrays of distributed sub-electrodes, a display driving unit used for providing public electrode driving signals to electrode arrays within the display time interval, a touch driving unit used for providing touch signal driving signals to sub-electrode arrays within the touch time interval, wherein the array substrate further comprises a first switching unit used for switching and outputting public electrode driving signals and touch electrode driving signals to all sub-electrode arrays in a time-sharing mode such that display driving and touch driving of the touch screen are carried out.

Description

technical field [0001] Embodiments of the present invention relate to touch screen technology, and more specifically, relate to a touch screen, a display device, and a driving method of the touch screen. Background technique [0002] The mature technology of touch screen, especially the in-cell (In Cell) touch screen has promoted the integration of screen touch. The subsequent time-sharing driving of the common electrodes also requires customization of both the display IC chip and the touch IC chip, and the compatibility among various ICs is greatly reduced. Contents of the invention [0003] Embodiments of the present invention provide a touch screen, a display device and a driving method of the touch screen. [0004] According to one aspect of the present invention, a kind of touch screen is proposed, comprising: [0005] An array substrate having a common electrode layer, the common electrode layer being divided into a plurality of sub-electrodes arranged in an array;...
