Problems solved by technology

[0004] However, the existing repair line structure will generate RC loading and reduce the signal transmission capacity due to crossing many signal lines
Moreover, as the repair line crosses more signal lines, the signal degradation will be more serious, making the repair line unable to perform as expected.

Embodiment 1

[0047] Please refer to FIG. 1A , which is a schematic top view of a first array substrate according to an embodiment of the present invention. The array substrate 100 includes a substrate 110, a plurality of signal lines 120 and at least one repair structure 140a. The array substrate 100 can be applied to a liquid crystal display panel, an organic electroluminescent display panel (such as an organic light emitting diode display panel (OLED), a polymer light emitting diode display panel (PLED)), or other display panels. The substrate 110 includes a transparent substrate (glass, quartz, or other materials), a flexible substrate (such as plastic, polyester, polymethacrylamide, or other materials), or an opaque substrate (such as a silicon wafer, ceramic , or other materials). The substrate 110 has an active area 112 and a peripheral area 114 adjacent to the active area 112 . The signal lines 120 are disposed on the substrate 110 and respectively connected to a plurality of pads ...

Embodiment 2

[0054] Please refer to FIG. 2A and FIG. 2B , which respectively illustrate schematic top views of the first array substrate according to Embodiment 2 of the present invention. The array substrates 200 and 200 a have two first repair lines 241 and second repair lines 242 . Taking the array substrate 200 as an example, the substrate 210 has an active area 212 and a peripheral area 214 adjacent to the active area 212 , and the scanning lines 220c, the first group of signal lines 220a and the second group of signal lines 220b are vertically arranged on the substrate 210 . The first group of signal lines 220 a and the second group of signal lines 220 b are respectively connected to the first group of pads 225 a and the second group of pads 225 b of the pads 225 , and the scanning lines 220 c are connected to the scanning line pads 225 c. The repair structure 240 is disposed on the peripheral region 214 , and the repair structure 240 has a first repair line 241 and a second repair l...

Abstract

The disclosed array substrate for display comprises a substrate with an active area and peripheral area, multiple signal lines on substrate, and at least one repair structure with a first / second repair line on the peripheral area. Wherein, the second repair line comprises a first branch line, and a second branch line; the first branch lies between the first repair line and second branch.

Description

technical field [0001] The present invention relates to an array substrate and its repairing method, and in particular to an array substrate with at least two branch repairing lines and its repairing method. Background technique [0002] With the improvement of manufacturing capacity and the increase of consumer demand, the flat panel display industry has entered the stage of mass production. In the process of mass production, it is inevitable that there will be defects. Taking the thin-film transistor substrate in the manufacturing panel as an example, it is necessary to form thousands of extremely fine signal lines on an extremely small glass substrate. Therefore, in the forming process, some signal lines often break or have poor signal transmission capability due to defects in the forming process. [0003] Therefore, a repair line (repair line) is produced in response to this situation. The so-called repair line is to form a line structure spanning multiple signal line...
