Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] In order to solve the problem that the VCOM voltage jump phenomenon affects the display quality of the liquid crystal display panel, in the prior art, the data (Data) signal input to the display IC is first processed and then input to the liquid crystal display panel for use, but This method cannot fundamentally solve the problem of VCOM voltage jump, and the effect of improving the display quality is still very limited.

Abstract

The invention discloses an embedded touch array substrate, a driving method thereof, and a display device. Wherein, the in-cell touch array substrate includes a common electrode layer, and the common electrode layer includes: a common electrode of the pixel part, corresponding to all pixel areas of the in-cell touch array substrate, and in the touch stage, the pixel part The common electrodes receive common electrode signals; the peripheral part of the common electrodes corresponds to at least part of the non-pixel regions except all pixel regions, and in the touch stage, the peripheral part of the common electrodes receives touch sensing signals. Through the present invention, the effect of improving the display quality of the liquid crystal display panel is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an in-cell touch array substrate, a driving method thereof, and a display device. Background technique [0002] At present, the touch panel and the liquid crystal display panel of most touch devices are set independently, the touch panel is set on the liquid crystal display panel, and there is a physical space between the liquid crystal display panel and the touch panel, therefore, in the liquid crystal display External light is reflected on the upper surface of the panel and the lower surface of the touch panel, which reduces the visibility of the LCD panel in brightly lit environments such as outdoors. If the visibility of the touch panel can be realized, the integration of the two can also realize the thinning and lightening of the entire display panel. [0003] Under the requirement of this technical development, the In Cell touch technology emerges and develops rap...
