Embodiment Construction

[0023] In order to further illustrate the gate driving circuit provided by the embodiments of the present invention, its manufacturing method, driving method, array substrate, and display device, a detailed description will be given below in conjunction with the accompanying drawings.

[0024] For a special-shaped display screen, the number of pixel units arranged in each row of pixels is likely to be different. If the number of pixel units set in each row of pixels of the special-shaped display screen is different, then the gate parasitic generated by each row of pixels will be approximately proportional to the number of pixel units in the corresponding row of pixels, so that each The gate parasitics generated by rows of pixels are also different, and the gate parasitics include gate parasitic capacitance and gate parasitic resistance; and because the structures of the shift register units at all levels in the gate drive circuit are the same, that is, each level of shift The ...

Abstract

The embodiment of the invention discloses a gate driving circuit, a manufacturing method thereof, a driving method, an array substrate and a display device, relates to the technical field of display,and is used for solving the problem that the display brightness of each row of pixels of a heterogeneous display screen is difficult to be consistent. The gate driving circuit includes a to-be-compensated shift register unit of at least one stage, wherein the drive end of the to-be-compensated shift register unit of each stage is connected with a gate line corresponding to the row of to-be-compensated pixels, and is also connected with a power line through a parasitic compensation unit. The parasitic compensation unit is configured to compensate for the drive end of the corresponding to-be-compensated shift register unit with the parasitic capacitance and / or the parasitic resistance, so that the to-be-compensated shift register units of all stages have the same drive load. The gate drivingcircuit and the manufacturing method thereof, the driving method, the array substrate, and the display device provided by the embodiments of the invention are used for row driving of the heterogeneous display screen.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate driving circuit, a manufacturing method thereof, a driving method, an array substrate, and a display device. Background technique [0002] With the development of display technology, the Organic Light Emitting Diode (Organic Light Emitting Diode) display device is recognized by the industry as one of the most promising display devices due to its advantages of thinness, bright color, and high contrast. [0003] At present, in order to meet the diverse needs of users, the shapes of the display screens in OLED display devices are also becoming more and more diverse, and some special-shaped display screens such as circular, elliptical, or polygonal shapes have appeared. However, for a special-shaped display screen, the number of pixel units set in each row of pixels is likely to be different, so that when the gate drive circuit is used to drive the row pixels of diffe...
