Abstract

The invention discloses a display panel and a display device. The display panel comprises a plurality of data lines, a Demux circuit, a plurality of signal transmission lines and a plurality of sub-pixels. The Demux circuit comprises at least two control signal lines and a plurality of control units, and each control unit is electrically connected with one corresponding control signal line and one data line. And each signal transmission line is electrically connected with at least two control units. Each sub-pixel comprises a pixel electrode and a common electrode, the pixel electrode and the common electrode are stacked and insulated to form a storage capacitor, and each pixel electrode is electrically connected with the corresponding data line. Wherein the data lines and the control lines are arranged on different layers, part of the data lines and at least one control signal line are overlapped on different layers, and the capacitance value of the storage capacitors of the sub-pixels and / or the common voltage accessed by the common electrodes are adjusted according to the overlapping frequency of the corresponding data lines and the control signal lines. According to the display panel, the charging difference among the multiple sub-pixels can be reduced, and the display uniformity of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] At present, in the design process of the display panel, in order to reduce the number of output channels of the driver chip, a Demux (Demultiplexer) circuit is usually added to the driver circuit of the display panel, so as to realize the output of the source driver chip. Channels are multiplied by purpose. For the Demux circuit, multiple control signal lines need to be set to drive the Demux circuit to work in time division. [0003] Among them, a coupling capacitance will be generated at the overlap of the data line and the control signal line, and the overlap times of different data lines and multiple control signal lines are different, so that the data voltages received by different data lines are subjected to the coupling from the control signal lines. Different effects lead to charging dif...
