Abstract
The present invention discloses a laser repairing apparatus for a display panel, which comprises a laser generating device, a bearing device, a backlight, a first polarizer, a second polarizer and an image generating device, the laser generating device is located above the bearing device, the first polarizer is located between the backlight and the bearing device, and the second polarizer is located between the image generating device and the bearing device. In the technical solution of the present invention, the first polarizer and the second polarizer are used to control the amount of light transmittance of the transmission light, and the human eye can identify the exact positions of the defective pixels quickly and accurately by means of the transmission image having overall low brightness, and consequently, the time required for the whole repairing process is shortened.
