The invention relates to a pixel circuit, an array substrate, a display panel and a display device. A pixel circuit, a pixel switch, a pixel capacitor, and a compensation circuit; the control pole of the pixel switch is connected to an external gate drive circuit, the first pole of the pixel switch is connected to an external data drive circuit, and the first pole of the pixel switch is connected to an external data drive circuit. The two poles are connected to the first pole of the pixel capacitor; there is a parasitic capacitance between the control pole and the second pole of the pixel switch; the second pole of the pixel capacitor is connected to the common electrode; the compensation circuit is connected to the pixel The first electrode of the capacitor; the compensation circuit is used to compensate the voltage change of the control electrode of the pixel switch when it is turned off, so as to slow down the voltage change of the first electrode of the pixel capacitor. In this embodiment, the voltages at the common electrodes in each pixel circuit are not much different or equal, so that the flickering phenomenon in the displayed image can be alleviated or eliminated, which is beneficial to improve the viewing experience.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit, an array substrate, a display panel, and a display device. Background technique [0002] At present, the pixel structure of the liquid crystal display, see figure 1 , the gate of the pixel TFT G1 is connected to the gate driving circuit Gate, wherein the input signal Gate of the gate driving circuit is low level VGL or high level VGH; the drain of the pixel TFT G1 is connected to the data driving circuit, and the input signal of the data driving circuit is gray step voltage Data; the source of the pixel TFT G1 is connected to the pixel capacitor Cs, which is the equivalent capacitance of the liquid crystal capacitor and the storage capacitor.
