The disclosure provides a transfer plate pre-processing device. The transfer plate comprises first and second surfaces, and recesses in an array are arranged on the first surface. The transfer plate pre-processing device comprises: a cylinder having a bearing surface that can be attached to the second surface of the transfer plate and to support the transfer plate; and a pressurization structure having a pressurizing surface. The cylinder can roll along the pressurizing surface, and when the cylinder is rolling, the first surface of the transfer plate is brought into contact with and pressed against pressurizing surface. Accordingly, the disclosure also provides a transfer plate pre-processing method and an alignment film preparation system. According the disclosure, the wettability of the transfer plate can be improved.

Plate pre-processing method and alignment film preparation system

A method and a system for repairing a defective pixel, and a display panel are provided, the method including: positioning a center of the defective pixel to obtain a center coordinate of the defective pixel; and repairing the defective pixel according to the center coordinate. By the method, the conventional manual alignment operation is replaced with the automatic positioning of the center coordinate, which not only accelerates repairing of the defective pixel, but also improves repairing efficiency, enhances overall efficiency and productivity of the device, and meanwhile, can solve the problem of unsuccessful repairing due to error in manual operation; and the accuracy of the repairing can be improved by automatically positioning the center.

Method and system for repairing defective pixel, and display panel

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.
