Problems solved by technology

[0003] However, in the touch stage, when a pulse signal of the same polarity is provided to the common electrode block, the common electrode block generates a corresponding electric field. If the liquid crystal is affected by the pulse signal of the common electrode block for a long time, the corresponding liquid crystal is prone to polarization. , resulting in poorly displayed

Abstract

The embodiment of the invention provides an array substrate, a display panel, a display device and a driving method for the array substrate, relates to the technical field of liquid crystal display, and aims to prevent a common electrode block from providing pulse signals of the same polarity for a long time in order to lower the polarizing probability of corresponding liquid crystal and improve undesirable display. The array substrate provided by the embodiment of the invention comprises a common electrode layer, at least one touch control signal line and a driving signal module, wherein the common electrode layer comprises at least one common electrode block; each touch control signal line is connected with a corresponding common electrode block; each touch control signal line is connected with the driving signal module; the driving signal module is used for outputting at least two touch control driving signals which are reverse in polarities to the at least one common electrode block at each touch control stage. The technical scheme is mainly applied to touch control liquid crystal display products.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate, a display panel, a display device and a driving method for the array substrate. Background technique [0002] The current liquid crystal display products can usually realize the touch function at the same time. The touch function is realized by the common electrode blocks distributed in matrix. In the display stage, the common electrode voltage is output to all the common electrode blocks. The common electrode block outputs a pulse signal as a touch driving signal, so that the common electrode block is multiplexed as a touch electrode, and at the same time, the touch position is determined by detecting the induction signal on each common electrode block. [0003] However, in the touch stage, when a pulse signal of the same polarity is provided to the common electrode block, the common electrode block generates a corresponding electric fi...
