The invention discloses a grid integrated driving circuit, an array substrate and a repair method thereof. According to the repair method, a repair signal line, a first reference signal line and repair units are arranged, wherein the repair signal line and the first reference signal line extend in the arrangement direction of all cascaded shifting registers, and the repair units are in one-to-one correspondence with all the cascaded shifting registers. After the shifting register with a problem in the grid integrated driving circuit is determined, it is required to determine that a signal control end of the repair unit corresponding to the shifting register with the problem and the repair signal line are connected at the overlapping position, a signal input end of the repair unit and the first reference signal line are connected at the overlapping position, a signal output end of the repair unit and a grid line are connected at the overlapping position, and a first reference signal of the first reference signal line substitutes an output signal of the shifting register to be loaded to the grid line to complete repair. Due to the fact that a voltage signal actually output to the grid line is provided by the first reference signal supplied by the first reference signal line, compared with the method that the voltage signal is output to the grid line by a signal supplied by the repair signal line, attenuation of the voltage signal actually output to the grid line is small.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a gate integrated drive circuit, an array substrate and a repair method thereof. Background technique [0002] At present, flat-panel displays are being vigorously promoted because of their ultra-thin energy saving. Most flat-panel displays use gate integrated drive circuits (GOA, GateDriveonArray) composed of multiple cascaded shift registers, which can save gate drive ICs. It can also reduce one production process, therefore, not only the production cost of the flat panel display is reduced, but also the production period is shortened to a certain extent. Based on this, GOA has been widely used in flat panel display manufacturing in recent years. [0003] For products using GOA, because a shift register is composed of multiple switching transistors (TFTs), many TFTs will be added on the array substrate, and some TFTs are large in size, and the line connections in the shift re...
