Embodiment 1

[0075] Example 1, see image 3 ( image 3 The dotted line area is the defect) and Figure 4 ( Figure 4 The middle shadow part is the black matrix, and the transparent part is the color layer).

[0076] Step S1011: Identify defects on the color filter.

[0077] Step S1012: It is determined that the defect is on the black matrix, and the coverage area corresponding to the defect on the black matrix is ​​identified as area 100 through border rectangleization.

[0078] Step S1013: Laser etching the region 100 by laser to form pinholes.

[0079] Step S1014: Fill the pinholes with black photoresist material to complete defect repair (see Figure 4 ).

Embodiment 2

[0080] Example 2, see Figure 5 ( Figure 5 The shaded area of ​​the irregular pattern in includes black matrix and black defect, where the black defect is caused by overfilling of black photoresist material) and Image 6 ( Image 6 The middle shadow part is the black matrix, and the transparent part is the color layer).

[0081] Step S1011: Identify defects on the color filter.

[0082] Step S1012: Determine that the defects are located on the R color layer, G color layer, and B color layer, identify the boundaries of the sub-defects on each color layer, and rectangularize the boundaries to obtain a defect area 100, wherein the rectangular coverage area of ​​the R color layer is area 101 , the rectangular coverage area of ​​the G color layer is the area 102 and the rectangular coverage area of ​​the B color layer is the area 103 .

[0083] Step S1013 : laser etching the region 101 , the region 102 and the region 103 to form pinholes.

[0084] Step S1014: Fill the red col...

Abstract

The invention relates to a repairing method and a repairing device. In the repairing method, gray scale information of a color film is obtained automatically, the gray scale information is compared with preset gray scale information, defects on the color film is identified; moreover, by judgement of a color layer where the defects are and a rectangular coverage area corresponding to the color layer, elimination of the rectangular coverage area and filling of a color resistance material, automatic identification, elimination an repairing for the defects can be realized. The method and the device have the advantages of having high degree of automation, reducing manual operations, improving color film defect repairing speed and repairing quality and reducing cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a repair method and device. Background technique [0002] The color filter (Color Filter, CF) is the main component of the LCD panel. It is composed of a large number of pixel matrices, but it is prone to white defects (dead pixels) during the production process. Once the LCD screen is made, the dead pixels will not be repaired. Therefore, it is necessary to improve the production yield through repairing, and repair the white defect in the color filter to the corresponding RGB color resist or repair it into a black photoresist, so that the substrate can reach the standard for entering the next process. [0003] The existing color film repair generally adopts the method of manual repair. The operator controls the equipment, and the human eyes recognize the size of the defect on the color film, and then according to the corresponding color layer (red (R), green (G), blue (B) colo...
