Embodiment Construction
[0044] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0045] In the narrow-frame products in the related art, when the connection between the Gate Signal and the gate line is disconnected, the pixels in this row will not be turned on normally, and the horizontal black line will be defective. If maintenance is not carried out, the product yield will be greatly reduced. If it is reduced, the cost of production will also increase, making designs such as narrow bezels meaningless and reducing product competitiveness.
[0046] In order to solve the above problems, an embodiment of the present application provides a display substrate, referring to Figure 1 to Figure 3 , the display substrate includes: a drive circuit 10, a first signal line 11 and a second signal line 12 extending along t...

The present application provides a method for repairing a display substrate, a display substrate and a display device, wherein the display substrate includes: a driving circuit, first signal lines and second signal lines extending along the column direction and alternately arranged along the row direction, and The third signal line extending along the row direction and crossing the first signal line and the second signal line; the second signal line includes the fourth signal line and the fifth signal line; since the fifth signal line is connected to the driving circuit, and the second signal line The fifth signal line crosses the third signal line vertically and horizontally, so when the connection between the fourth signal line and the third signal line is disconnected, the fifth signal line can be connected to the disconnected third signal line, so that the driving circuit The driving voltage signal can be provided to the third signal line through the fifth signal line, thereby repairing display abnormalities such as defective black lines due to disconnection, and improving the yield rate and competitiveness of display products.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a repair method for a display substrate, a display substrate and a display device. Background technique [0002] With the development of technology and breakthroughs in narrow bezels in other application categories, products with narrower bezels can better reflect the competitiveness of products and impress consumers to buy them. Therefore, it is extremely urgent to develop display products with narrower bezels. [0003] In order to realize display products with narrow borders, S_IC and Gate_IC are fabricated on one side in the related technology to realize ultra-narrow border design on three sides. In this design, the Data Signal is parallel to the Gate Signal, and the Gate Signal passes through the via hole and the gate line in the horizontal direction. connect. However, products with this design are prone to poor horizontal black lines, resulting in lower product yields. C...
