Specific embodiment
The display that there is a problem of foreign matter for liquid crystal display device mould group existing in the prior art and generate is bad, this
Inventive embodiments provide the method for maintaining and device of a kind of display module.Firstly, display module provided in an embodiment of the present invention
Method for maintaining process as shown in Figure 1, above-mentioned display module provided in an embodiment of the present invention method for maintaining, successively execute step
It is rapid as follows:
S101, it determines defective region of the display module there are foreign matter, and determines multiple test points in defective region；
S102, the laser for emitting at least one test point preset strength with multiple polarizing angles, and receive test point
Each reflected light；
S103, the best polarizing angle that defective region is determined according to each reflective light intensity of test point；
S104, laser is emitted to defective region with best polarizing angle, defective region is repaired.
Since the polaroid and protective film of display module can generate barrier effect to maintenance laser, the present invention is real
The above method for applying example offer determines optimal laser light incident polarisation according to test point reflective light intensity under different polarizing angles
Angle is more advantageous to laser action to foreign matter, foreign matter is smashed, so that the effect of optimization maintenance foreign matter, guarantees display module

Specifically, in above-mentioned step S103, the best inclined of defective region is determined according to each reflective light intensity of test point
Angular can specifically include:
It is according to each reflective light intensity of test point, the corresponding polarizing angle of minimum value in each reflective light intensity of test point is true
It is set to best polarizing angle.
Since the laser for repairing foreign matter needs the array substrate side incidence by display module, therefore, it is necessary to pass through battle array
The protective film and polaroid of column substrate-side are applied on foreign matter, and the energy of laser is certain, if the reflective light intensity received
Smaller, then the laser energy for being applied to foreign matter by protective film and polaroid is bigger, as a result, by the minimum value pair in reflective light intensity
The polarizing angle answered is determined as best polarizing angle.
In practical application, tunable laser polarisation principal axis transformation, successively increases 10 degree with the polarizing angle being emitted every time,
Successively at least one test point into defective region emits laser again, determines best polarization angle according to the reflective light intensity of test point
Degree.For example, laser emits laser when polarizing angle is a, to test point A, the reflective light intensity of acquisition is Λ；Laser is inclined
When angular is a+10 °, emit laser to test point A, the reflective light intensity of acquisition is Ξ；Laser is a+20 ° in polarizing angle

The maintenance highest point of foreign matter in defective region, can specifically include:
Duration used when according to the reflected light for receiving each test point, by the corresponding test point of minimum value in each duration
Position is determined as the maintenance highest point of foreign matter in defective region.
When the highest point to foreign matter emits laser, due to the distance minimum of foreign matter highest point to array substrate, i.e. foreign matter
The distance of highest point to laser emitting source is also minimum, relative to other each points, receives after reflecting transmitting laser anti-
It is also minimum to penetrate all durations of light.
In practical application, best polarizing angle when can set laser maintenance foreign matter, and make laser in bad area
Multiple test points in domain carry out mobile and emit small energy laser simultaneously, and according to receive laser reflection signal it is all when
The long maintenance highest point to determine foreign matter.For example, the laser that laser is M to 1 emitted energy of test point in defective region, note
The reflection interval for recording laser is T1；The laser that laser is M to 2 emitted energy of test point, the reflection interval of recording laser are T2；
The laser that laser is M to 3 emitted energy of test point, the reflection interval of recording laser are T3；And so on, in the feedback of record
Extract minimum value in time, and by the corresponding test point position of the minimum value be determined as polarizing angle be determined as it is different in defective region
The maintenance highest point of object.
Further, as shown in figure 3, after above-mentioned step S202, in the above method provided in an embodiment of the present invention,
Further include following steps:
S301, the laser of preset strength is emitted to maintenance highest point position with best polarizing angle, and acquires maintenance highest
The maintenance image of point position；
S302, the brightness relationship repaired between image and preset standard picture according to acquisition, adjust the transmitting of laser
Intensity is with the best lasing intensity of determination；
As a result, in above-mentioned step, laser is emitted to maintenance highest point with best polarizing angle, defective region is carried out
Maintenance, can specifically include:
Laser is emitted to maintenance highest point position with best polarizing angle and best lasing intensity, to defective region into
Row maintenance.
It in the specific implementation, can be according to acquisition between the image and standard picture when repairing highest point transmitting laser
Brightness relationship, to adjust lasing intensity, to determine that best lasing intensity repairs maintenance highest point, thus
Foreign matter can be not enough to repair to avoid insufficient due to lasing intensity, or make to show since lasing intensity is excessive
The impaired situation of mould group improves the yield of maintenance to further increase maintenance accuracy.
Specifically, in above-mentioned step S302, according to bright between the maintenance image of acquisition and preset standard picture
Degree relationship adjusts the emissive porwer of laser with the best lasing intensity of determination, can specifically include:
When the brightness of the maintenance image of acquisition is less than the brightness of standard picture, increase lasing intensity, in acquisition
When the brightness of maintenance image is greater than the brightness of standard picture, reduce the emissive porwer of laser, makes the service action drawing acquired after adjustment
The brightness of picture and the brightness of standard picture are consistent；

The middle image by multiple test and verification, the standard picture are applicable to all display module maintenances.In practical applications, may be used
The brightness relationship of the maintenance image and standard picture that acquire when according to each transmitting laser adjusts lasing intensity, makes and standard
Corresponding lasing intensity is as best lasing intensity when brightness of image is consistent.For example, emitting to maintenance highest point
Laser energy is M when laser, and the maintenance image acquired at this time color compared with standard picture is shallower, i.e. the brightness of the maintenance image
Less than the brightness of standard picture, at this time, it is possible to increase laser is sent to intensity, emits laser to maintenance highest point again, until
It is when the maintenance image of acquisition is consistent with the brightness of standard picture, lasing intensity at this time is strong as best Laser emission
Degree.
The best polarizing angle of laser used, the maintenance highest point of foreign matter and most when having determined to defective region maintenance
After good lasing intensity, laser is emitted to maintenance highest point, so that the foreign matter being located in display module be smashed, makes to show
Gap in mould group between array substrate and opposite substrate reverts to normal value, is shown due to caused by foreign matter to be mitigated or eliminated
Show bad.
