Problems solved by technology
The inventors have found through research that, due to the close distance between the gate electrode layer and the source-drain metal layer, the distance between the gate line and the data line formed in the display area is relatively short, resulting in the existence of a grid line and a data line in the OLED display substrate. Defective points formed by short-circuit (Data Gate short, DGS for short) will cause horizontal and vertical stripes on the OLED display substrate, reducing the display effect of the OLED display substrate.

The invention discloses a display substrate and a manufacturing method thereof, and a display device. The display substrate comprises a substrate, and grid lines, data lines, power supply connecting lines and a plurality of sub-pixels which are arranged on the substrate, wherein the display substrate has bad points formed by short circuit of the grid lines and the data lines, the grid lines forming the bad points are bad grid lines, the data lines forming the bad points are bad data lines, the power supply connecting line and the gate electrodes of a plurality of transistors are arranged on the same layer, the bad grid lines and bad power supply connecting lines are disconnected, the display substrate further comprises repair lines arranged on the sides, away from the substrate, of the source and drain electrodes of the transistors, and the repair lines are connected with the bad grid lines which are partially disconnected and the bad power supply connecting lines which are partially disconnected and used for transmitting scanning signals so as to repair the display substrate. According to the technical scheme provided by the invention, the bad grid lines and the bad power supply connecting lines are disconnected, and the repair lines are arranged to repair the bad points, so that the display effect of the display substrate is ensured.
Description
technical field [0001] This article relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display substrate has ultra-thin, large viewing angle, active light emission, high brightness, continuously adjustable light color, low cost, fast response speed, low power consumption, wide operating temperature range and flexible Display and other advantages, has gradually become a promising next-generation display technology. According to different driving methods, OLED can be divided into passive matrix drive (Passive Matrix, PM) type and active matrix drive (Active Matrix, AM) type. Film Transistor (TFT) controls each sub-pixel, and each sub-pixel can be continuously and independently driven to emit light. [0003] The display area of the OLED display substrate includes: criss-cross gate lines and data lines. Generally, the gate lin...
