Abstract

The invention discloses an array substrate, a display panel and a display device. The array substrate comprises a gate driving circuit, wherein the gate driving circuit comprises a plurality of cascaded shift register units, each shift register unit is connected with a scanning line, and the plurality of cascaded shift register units are electrically connected through cascaded wires; each shirt register unit comprises a bootstrap capacitor; the bootstrap capacitor comprises a first pole plate, the first pole plate is arranged in a mode of being overlapped with the corresponding cascade wire, and the part, which is overlapped with the first pole plate, of the cascade wire is multiplexed as a second pole plate of the bootstrap capacitor. Therefore, the second pole plate of the bootstrap capacitor is not required to be additionally arranged, thereby being capable of reducing the layout area occupied by the bootstrap capacitors on the array substrate, thus being capable of reducing the layout area of the whole gate driving circuit, and being conducive to a narrow frame design of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to an array substrate, a display panel and a display device. Background technique [0002] Display devices such as liquid crystal display (liquid crystal display, LCD) or organic light-emitting diode (Organic Light-Emitting Diode, OLED) display devices have the advantages of low radiation, small size and low energy consumption, and are widely used in notebook computers, personal In information products such as digital assistant (Personal Digital Assistant, PDA), flat-screen TV and mobile phone. [0003] The drive circuit of the display device includes: a pixel array for displaying an image; a data drive circuit that supplies data signals to the pixel array through a data line; a gate pulse (or scan pulse) that is synchronized with the data signal is sequentially provided through a scan line Gate drive circuits for pixel arrays, etc. [0004] At present, GOA techn...
