Problems solved by technology

[0004] Since the spot size of the laser beam cannot be adjusted by scanning, when repairing a certain pixel of the display screen, when the spot size of the laser beam is too large, it is easy to cause other pixels around the pixel to be affected by the burning of the laser beam. Cause damage, poor repair effect

Abstract

The invention provides a laser repair device. The laser repair device comprises a laser emitter, a light guiding assembly and a slit structure. The slit structure comprises a first group of light blocking sheets and a second group of light blocking sheets which are overlaid on the laser emitting path. The first group of light blocking sheets comprises two first light blocking sheets which are located on the same plane and can oppositely move. The second group of light blocking sheets comprise two second light blocking sheets which are located on the same plane and can oppositely move. The twofirst light blocking sheets form a first slit. The two second light blocking sheets form a second slit. The first slit and the second slit intersect. The intersection point of the first slit and the second slit is located on the laser emitting path. The slit structure is used for allowing the laser beam emitted by the laser emitter to pass through and controlling the radial dimension of the laserbeam. The laser repairing device can effectively control the size of the spot of the laser, improve the repair accuracy and prevent pixels around a repaired area from being damaged.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of repairing display screens, in particular to a laser repairing device. Background technique [0002] In the display industry, the production of liquid crystal display panels (LCD for short) often produces some defects such as bright spots, flash points, and broken spots. [0003] In the prior art, aiming at defects in the production process of LCD display screens, a film layer of LCD products is usually carbonized by means of vibrating mirror scanning (Direct Method, DM process for short), and the high heat generated by the laser beam is used to oxidize The indium tin layer is carbonized layer by layer to achieve the purpose of removing the defects of the display screen. [0004] Since the spot size of the laser beam cannot be adjusted by scanning, when repairing a certain pixel of the display screen, when the spot size of the laser beam is too large, it is easy to cause other pixels...
