[0003] At present, there are laser transmitters that emit ultra-high frequency, but the current way to control the laser transmitter to move back and forth is to drive the laser transmitter to move back and forth by controlling the movement of the machine (Gantry) in the xy direction to repair the single pixel. the entire area, such as figure 1 As shown, since the weight of the machine 100 and the laser emitter 200 is relatively large, and the width of a single pixel 300 is generally less than 100 μm, the laser emitter 200 is controlled to move back and forth within a small distance (figure 1 (indicated by the middle arrow) is extremely restricted and becomes the bottleneck of maintenance speed and effect

Embodiment Construction
[0029] The specific implementation manners of the defective display panel repairing device and the repairing method provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0030] A device for repairing defective display panels provided by an embodiment of the present invention, such as figure 2 As shown, it includes: a laser transmitter 001 with a fixed position, a first reflective flat mirror 002 arranged on the optical path of the laser emitter 001 emitting laser light, and a control component 003 connected to the first reflective flat mirror 002; wherein,
[0031] The control part 003 is used to drive the first reflective plane mirror 002 to rotate around the rotation axis A within the set angle range α;
[0032] The first reflective plane mirror 002 is used to reflect the laser light emitted by the laser emitter 001 to the defective pixel area 004 of the display panel to be repaired.
[0033] S...

The invention discloses a device and method for repairing an abnormal display panel. The device comprises a laser emitter, a first reflecting plane mirror and a control part, wherein the position of the laser emitter is fixed, the first reflecting plane mirror is arranged on an optical path of laser emitted by the laser emitter, and the control part is connected with the first reflecting plane mirror; the control part is used for driving the first reflecting plane mirror to rotate around a rotating shaft in a set angle range and driving the first reflecting plane mirror to reflect the laser emitted by the laser emitter to a to-be-repaired abnormal pixel region of the display panel. The relatively heavy laser emitter is in a static state, and the to-be-repaired abnormal pixel region is repaired through the laser by controlling the first reflecting plane mirror to rotate, so that the speed of moving back and forth of the laser is greatly increased, and the purposes of increasing the laser repairing speed and the repairing effect are achieved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a device for repairing a defective display panel and a method for repairing it. Background technique [0002] At present, when a defective pixel of a product such as a display panel is detected, it is necessary to use a high-frequency laser to repair the defective pixel area, that is, to irradiate the defective pixel area with laser. Theoretically, the faster the laser moves and the higher the frequency, the straighter the repair edge will be and the smaller the broken substrate powder will be, so the repair effect on the defective pixel area will be better. [0003] At present, there are laser transmitters that emit ultra-high frequency, but the current way to control the movement of the laser transmitter is to move the laser transmitter back and forth by controlling the movement of the machine (Gantry) in the xy direction to repair the single pixel. the entire area, such as ...
