Substrate, manufacturing method of substrate and display device

Abstract

The invention provides a substrate, a manufacturing method of the substrate and a display device. The substrate comprises a substrate as well as a plurality of grid lines and at least three grid driving circuits, wherein the grid lines and the grid driving circuits are formed on the substrate; the at least three grid driving circuits are uniformly arranged in the extension directions of the grid lines; each grid scanning driving circuit is provided with a plurality of output ends and is used for outputting a plurality of scanning pulses through the plurality of output ends in sequence; an output end connected with the grid line is arranged in a position of each grid line, of each grid driving circuit; the grid driving circuits are applicable to each grid line of the plurality of grid lines; synchronous scanning pulses can be output to the grid lines through the output ends connected with the grid lines. Compared with the prior art, the substrate is short in distance between a position point which is relatively far away from the grid driving circuits, of position points on the grid lines, and the grid driving circuits, so that the time delay that signals are transmitted to the position point can be shortened, and the time difference that the position points receive scanning signals can be reduced.

Description

technical field [0001] The invention relates to a substrate, a manufacturing method thereof, and a display device. Background technique [0002] In order to achieve a narrower frame of the display device, a GOA (GateDriver On Array, gate driver circuit fabricated on an array substrate) design is proposed in the prior art. On the other hand, in a display device, especially a large-scale display device, the length of the gate line on the array substrate is relatively large, resulting in a large resistance between the two ends of the gate line and forming more overlap capacitance with other metal layers. , resulting in a large delay (RC delay) when the scanning signal provided by the gate drive circuit is transmitted from the near-end to the far-end on the gate line, resulting in a difference in the moment when the near-end sub-pixel and the far-end sub-pixel receive the scan signal If it is large, it will affect the writing of data voltage.
