Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.
As it is shown in figure 1, the display screen detection device that one embodiment of the invention provides includes microscope carrier 100 and camera 200, its
In:
Microscope carrier 100 include fixing base plate 1, sliding floor 2, for clamping the fixture 3 of mobile terminal, and first drives dress
Putting (not shown), sliding floor 2 is slidedly assemblied in the top of fixing base plate 1, and fixture 3 is arranged on sliding floor 2 also
Hinged with sliding floor 2, the first driving means is used for driving sliding floor 2 to be relatively fixed base plate 1 and slides into setting position, and drives
The dynamic relative sliding floor 2 of fixture 3 overturns set angle；
Camera 200 is positioned at above microscope carrier 100 and camera lens is towards sliding floor 2.
The step that display screen is detected by the display screen detection device using above-described embodiment to provide is as follows:
Being installed to by mobile terminal on fixture 3, fixture 3 is horizontal positioned, now, mobile terminal when overturning
Display screen falls into the range of observation of camera lens, and display screen can be faced defects detection by camera 200；
Being driven fixture to 3 upset set angles by the first driving means, now display screen is sent out relative to the position of camera lens
Changing, therefore the first driving means sliding floor to be driven 2 is relatively fixed base plate 1 and moves in parallel to display screen and again fall into
Position in the range of observation of camera lens, as in figure 2 it is shown, now, the display screen tilting certain angle can be entered by camera 200
Row defects detection.
The detection method utilizing this device can effectively improve accuracy and the detection efficiency of detection display screen defect,
It also is able to alleviate to a great extent the labor intensity of operator.
Preferably, the jointed shaft of fixture 3 and sliding floor 2 is perpendicular to the glide direction of sliding floor 2, when sliding floor 2
After moving in parallel setpoint distance, the center of display screen can be made to overlap with the optical center of camera 200.
During realizing the present invention, inventor has carried out substantial amounts of defect detection ratio testing experiment.Concrete, right
500 have defective display screen under differing tilt angles (respectively 15 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, 50 °,
55 °, 60 °, 65 °, 70 °, 75 °) detect, defect detection ratio is as follows:
When display screen tilts 15 °, detecting defective 63, defect detection ratio is 12.6%；
When display screen tilts 20 °, detecting defective 110, defect detection ratio is 22.0%；
When display screen tilts 25 °, detecting defective 201, defect detection ratio is 40.2%；
