Abstract

The present invention provides a display panel, a device and a driving method for solving the technical problem in the prior art that the common voltage signals input to each common electrode block are not equal, resulting in poor display effect of the display panel. The display area of ​​the display panel includes a plurality of common electrode blocks arranged in an array, and the common electrode blocks are multiplexed as touch electrodes; the non-display area of ​​the display panel includes signal control lines, at least one gate driving circuit, and a control circuit and at least one pair of clock signal lines; the input end of the control circuit is electrically connected to the at least one pair of clock signal lines and the signal control line, and the output end of the control circuit is electrically connected to each of the common electrode blocks; the control circuit is used for : According to the control signal provided by the signal control line and the clock signal provided by the at least one pair of clock signal lines, the common electrode blocks are controlled to be electrically connected to each other in the display stage and disconnected from each other in the touch stage.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a device and a driving method. Background technique [0002] With the development of self-capacitive touch display technology, the common electrode of the array substrate of the display panel can also be used as the touch sensing electrode for self-capacitive touch detection, and the touch control and control can be performed in a time-sequential manner through time-sharing driving. Display control, which can realize touch and display functions at the same time. In this way, the touch sensing electrodes are directly integrated into the display panel, which greatly reduces the manufacturing cost, improves the production efficiency, and reduces the thickness of the panel. [0003] refer to figure 1 , figure 1 It is a schematic structural diagram of a common display panel in the prior art, including: a common electrode layer and a wiring layer oppositely...
