Example Embodiment

[0031] In the assembly (Cell) process, automatic laser repair is to solve the problems existing in the previous technology, thereby shortening the time required for the laser repair process (Tact time), thereby increasing production capacity, and reducing the chance of manual operation errors, To improve the repair success rate. Below is a display panel as the object to be repaired, and the technology of the present invention is described in detail according to the embodiment.

[0032] Before laser repair, the process of defect detection and classification will be carried out;

[0033] In detail, in the lighting test process, the defect code (Defect code) and defect address (Defect address) on the display panel will be reported to the inspection system, and a defect code corresponds to a defect location;

[0034] Continuing with the defect classification (Sorting) of the laser repair front station, various defect panels are classified, that is, the display panels with defects...

Abstract

The invention mainly relates to a Laser repair method, in particular to an automatic laser repair method for repairing defects generated during manufacturing a display panel. The method comprises the following steps: at least one panel to be repaired is provided, and the panel to be repaired has at least one defect and is processed by classification of defects to have the defect of only one laser path; according to a defect position, a laser head automatically moves to the defect position and selects a corresponding laser prescription; and a laser path is automatically displayed according to the laser prescription, and the only one laser path is utilized to automatically laser the defect for repairing. The automatic laser repair technology can effectively shorten the Tact time required by a laser repair processing procedure so as to improve the productivity, reduce the opportunity of manual operation errors and improve the repair success ratio.

Description

technical field [0001] The present invention mainly relates to a laser repair method, in particular to an automatic laser repair method for repairing defects generated in the manufacture of display panels. Background technique [0002] In the liquid crystal display panel (LCD) manufacturing process, from the front-end array (Array) process, assembly (Cell) process, until entering the module (Module) process, the liquid crystal display panel has completed most of the chemical, physical processing and material combination. The procedures and flaw detection are carried out to ensure the quality. Next, the driver IC and circuit board are installed in the module manufacturing process, and then assembled with the backlight to form a liquid crystal module. [0003] Although the liquid crystal display panel technology is quite mature now, it is inevitable that there will be defects in the panel production process. These defects will cause abnormal bright spots on the display. If the...
