Display screen intelligent detection laser repairing method

Abstract

The invention discloses a display screen intelligent detection laser repairing method. The method comprises the following steps of firstly, carrying out automatic feeding, then controlling a visual identification system to scan a display panel and identify defective pixels in the display panel, and carrying out clearing operation on the defective pixels through a laser machining system; after thelaser machining system finishes machining, controlling the visual identification system to quickly scan the display panel again, and re-checking whether the known defective pixels of the panel are qualified or not; if the machining effect is qualified, controlling automatic discharging; if the machining effect is not qualified, machining the defective pixels after intelligent analysis and processing; and after machining is completed, detecting and confirming the machined defective pixels again through the visual identification system, carrying out blanking after machining is qualified, if machining is not qualified, repeating the re-inspection analysis and the machining process, and repeating the steps till the machining effect is qualified. The display screen intelligent detection laser repairing method effectively improves the detection repairing efficiency, in addition, reduces the labor intensity and the labor cost and improves the product yield, and the practicability is high.

Description

Technical field: [0001] The invention relates to a laser repair method for intelligent detection of a display screen, and relates to the technical field of laser repair. Background technique: [0002] At present, in the production process of the display panel, after the aging process of the display panel is completed, it is necessary to check and mark its display defects, and repair the repairable display defects. The commonly used methods for checking and repairing display screens are as follows: firstly, an artificial hand-held microscope is used to inspect the display defects; then, the display defect parts are marked; the third step is to transfer the marked substrate to the laser repair station to position the display defect parts again; The fourth step is to perform laser repair on the display defects. Although this inspection and repair method is simple to operate and widely used because it is easy to use, there are some obvious display defects at the same time. The...

Problems solved by technology

Although this inspection and repair method is simple to operate and widely used because it is easy to use, there are some obvious display defects at the same time. The accuracy rate depends on human factors, which has high requirements for operators and artificially affects the product yield of the display panel, so the labor cost is high
