摘要： A gate driving unit circuit comprises an input sub-circuit and an output sub-circuit. The input sub-circuit is connected to a first pull-up node, a second pull-up node, and an input terminal, and transmits a signal input from the input terminal to the first pull-up node and the second pull-up node. The output sub-circuit is connected to the first pull-up node, the second pull-up node, a first control terminal, a third control terminal, a first output terminal, and a second output terminal. The output sub-circuit transmits a signal input through the first control terminal to the first output terminal, and transmits a signal input through the third control terminal to the second output terminal under the control of a potential of the second pull-up node, wherein, an effective voltage of a signal of the first control terminal is greater than that of a signal of the third control terminal.

摘要： A shift register unit is provided, which includes an input circuit, a first output circuit and a first output signal adjustment circuit. The input circuit is configured for receiving an input signal from an input terminal and controlling an electrical signal of a first node based on the input signal. The first output circuit is configured for outputting a first output signal at a first output terminal of the shift register unit based on a first clock signal under control of the electrical signal of the first node. The first output signal adjustment circuit is configured for providing a first reference signal to the first output terminal under control of the second clock signal so as to decrease an amplitude of the first output signal.

摘要： A Mura compensation circuit and method, a driving circuit and a display device are provided. The Mura compensation circuit comprises: a vertical Mura compensation unit, for providing a corresponding gamma voltage to a vertical block Mura region and a vertical non-Mura region of a display panel respectively, to compensate for a vertical Mura phenomenon; and/or a horizontal Mura compensation unit, for providing a corresponding gate drive signal and/or a corresponding charging/discharging control signal to a horizontal block Mura region and a horizontal non-Mura region of a display panel respectively, to compensate for a horizontal Mura phenomenon. The Mura compensation circuit can make the different regions of the display panel have the same display effect, and improve reduction of display quality caused by impedance difference at different positions of the display panel, thereby raising the quality of a picture, and can be promoted and applied widely.

摘要： An array substrate and a manufacturing method thereof are provided. The method for manufacturing the array substrate includes: forming a passivation layer on a base substrate; forming photoresist on the passivation layer, and forming a first photoresist pattern including a photoresist-completely-retained region, a photoresist-partially-retained region and a photoresist-completely-removed region, by exposure and development processes; forming a first through hole in the passivation layer by etching the passivation layer with the first photoresist pattern as a mask; forming a second photoresist pattern by performing ashing on the first photoresist pattern to remove the photoresist in the photoresist-partially-retained region and reduce a thickness of the photoresist in the photoresist-completely-retained region; and etching the passivation layer with the second photoresist pattern as a mask, so as to reduce a thickness of the passivation layer in the photoresist-partially-retained region.
