Abstract

The present invention discloses an array substrate, a display panel, and a display device. The array substrate includes a plurality of pixel regions arranged in an array on a substrate. Each of the pixel regions includes a pixel electrode, a common electrode, a compensation electrode, and a control circuit. The compensation electrode is insulated from the common electrode. The orthographic projection of the compensation electrode on the substrate and the orthographic projection of the pixel electrode on the substrate have an overlapped region. The orthographic projection of the common electrode on the substrate and the pixel electrode have an overlapped region. The control circuit is configured to turn on the pixel electrode and the compensation electrode when charging the pixel electrode.By virtue of the compensation electrode and the control circuit, when the compensation electrode is disconnected from the pixel electrode, both the compensation electrode and the common electrode form a capacitor with the pixel electrode, and the increase of a capacitance value can ensure the voltage stability on the pixel electrode, thereby improving the display quality. .

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements for the display quality of the display panel. However, due to the influence of the internal structure of the display panel, the voltage driving the display will change, resulting in distortion of the display picture. [0003] The array substrate of the display panel in the related art includes a thin-film transistor (Thin-Film Transistor, TFT). The source electrode and the gate of the TFT will form a parasitic capacitance, and the drain electrode and the gate will also form a parasitic capacitance. When the gate line on the TFT is turned on and off, the gate of the TFT will produce a voltage change. Due to the coupling effect of capacitance, the voltage on the source electrode and the dra...
