Display panel pixel repairing light path system and display panel pixel repairing method

Abstract

The embodiment of the invention discloses a display panel pixel repair light path system and a display panel pixel repair method. The display panel pixel repair light path system comprises a laser module, a first diaphragm, an objective lens module, a camera module and a control module, wherein the camera module and the laser module are electrically connected with the control module; the objectivelens module comprises a first objective lens, and the magnification factor of the first objective lens is greater than or equal to 100*; the camera module is used for observing the display panel through the first diaphragm and the first objective lens so as to determine the position information of a defective sub-pixel and sending the position information to the control module; and the control module is used for controlling the laser module to emit a laser beam and controlling the direction of the laser beam emitted by the laser module according to the position information, so that the laserbeam sequentially passes through the first diaphragm and the first objective lens and then focuses on the defective sub-pixel to repair the defective sub-pixel. The display panel pixel repair light path system has high processing precision.

Description

technical field [0001] Embodiments of the present invention relate to a display panel repair technology, and in particular, to a display panel pixel repair optical path system and a display panel pixel repair method. Background technique [0002] With the continuous development of science and technology, the display industry has continued to improve its technical level from the first picture tube display, to the later LCD screen display, to LED, OLED, and now to AMOLED, QLED, Mini LED, Micro LED, etc. [0003] In the prior art, repairing technology is usually used to repair display panels with a small number of defects, so as to improve the yield and avoid waste. For example, repair technologies mainly include cathode isolation (Isolation), direct carbonization (Burning) and single point processing (Single Shot) and other technologies. [0004] However, the existing repair systems are mainly for repairing display panels with large single sub-pixels, such as display panels f...

AI Technical Summary

Problems solved by technology

[0004] However, the existing repair systems are mainly aimed at repairing display panels with large single sub-pixels, such as display panels for mobile phones and computers, where the size of a single sub-pixel is on the order of more than ten microns

If the existing repair system is used to repair smaller-sized sub-pixels, there will be problems such as unclear sub-pixels and low processing accuracy.
