Embodiment 1

[0037] An embodiment of the present invention provides a method for repairing a long line of a COA array substrate, which can be applied to a long line repair process of a COA array substrate. Such as figure 1 with figure 2 As shown, the COA array substrate in this embodiment includes a glass substrate 1, a scanning line 21 located on the first metal layer, a data line 22 located on the second metal layer, a first insulating layer 31, a second insulating layer 32, a color resist 41. Color resistance 42. Transparent electrode 5. Wherein, the first insulating layer 31 and the second insulating layer 32 are usually made of silicon nitride, the transparent electrode 5 is usually made of indium tin oxide (ITO), and the data line 22 is the metal line to be repaired in this embodiment.

[0038] After the long-line area is determined, the long-line repair can be carried out. The long-line repair method includes:

[0039] S11 : opening via holes 6 at both ends of the long line area...

Embodiment 2

[0048] Such as Figure 5 with Image 6 As shown, the COA array substrate in this embodiment is basically the same as that in Embodiment 1, including a glass substrate 1, scanning lines 21 located on the first metal layer, data lines 22 located on the second metal layer, a first insulating layer 31, and a second metal layer. Two insulating layers 32 , color resist 41 , color resist 42 , transparent electrode 5 . The difference between this embodiment and the first embodiment is that the metal line to be repaired in this embodiment is the scan line 21 .

[0049] The long line repair method provided by the embodiment of the present invention includes:

[0050] S21: Opening first via holes 61 at both ends of the first long line region to expose the scan lines 21 .

[0051] Specifically, a laser is used to drill holes at both ends of the first long line region, and the formed first via hole 61 should penetrate the first insulating layer 31, the second insulating layer 32, the co...

Abstract

A long-line repair method for a COA array substrate comprises: providing via holes (6) at two ends of a long-line area to expose a data line (22), removing a transparent electrode (5) and coloured resistors (41, 42) of the long-line area to form a groove (7), and forming long-line metal (8) in the groove (7) and connecting two ends of the long-line metal (8) to the data line (22) through the via holes (6), thereby implementing the long-line repair for the data line (22).

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for repairing long lines of a COA array substrate. Background technique [0002] With the development of display technologies, liquid crystal displays have become the most common display devices. [0003] At present, people's demands on the display quality of liquid crystal displays continue to increase, so the technology of disposing color resistance and black matrix on an array substrate (Color Filter on Array, COA for short) has been more and more applied in liquid crystal displays. Because the color resistance and black matrix in COA technology are set on the array substrate, the alignment between the color resistance layer and the metal circuit is more accurate, which can avoid the reduction of aperture ratio and the The problem of light leakage is eliminated, thereby improving the display quality of the liquid crystal display. [0004] In the manufacturing proce...
