Primary use:

The electrical inspection in the optical inspection can only passively find the position of the pixel defect, The purpose of laser repair is to further hope that the defective parts can be corrected, so that the waste products that were originally screened out to be discarded can be repaired into acceptable products. According to the current acceptable product standards, firstly, there must be no wired defects; secondly, many products currently have a "no bright spot guarantee", so there cannot be pixels that are always shining bright spots, but a few dark spots can be accepted to a certain extent. Therefore, the objects of laser repair are mainly line defects and bright spots.

The way of laser repair:

Welding: At the span where two layers of metal overlap each other, with a laser of appropriate energy and wavelength, The metallization can be opened and fused together to form a short circuit between two otherwise disconnected electrodes. The size of the overlap area and its distance from other surrounding metals should be considered in the design. In addition to the single-layer metal wiring, the metallization can be opened by a laser of appropriate energy and wavelength, and the original wiring can be cut. The size of the width and its distance from other surrounding metals need to be considered in the design.
