Step 403, contraposition the first display panel of fitting and the second display panel, the second viewing area are included in perpendicular to first
With the sub- viewing area in the first viewing area equitant first on the direction of the light-emitting surface of display panel, and do not hand over the first viewing area
The sub- viewing area of folded second；
The second sub-pixel in the first sub-pixel and the first viewing area in first sub- viewing area is arranged in a one-to-one correspondence；
In the display stage, the second sub-pixel in the second display panel in the second sub- viewing area keeps normally-black display or does not show
Show.
Specifically, continuing to refer to figure 1-Fig. 3, Fig. 6, in the production method of display module provided in this embodiment, first is aobvious
Show that the first viewing area AA1 in panel 100 along the length of first direction X is L1, the width of the first viewing area AA1 Y in a second direction
For D1, second viewing area AA2 is L2 along the length of first direction X in the second display panel 200, and the second viewing area AA2 is along second
The width of direction Y is D2；Wherein, L2 > L1 > 0, D2 > D1 > 0, the area of the second viewing area AA2 in the second display panel 200
Greater than the area of the first viewing area AA1 in the first display panel 100, the first display panel 100 and the second display panel 200 into
When row contraposition fitting, even if can also make in display module the first viewing area AA1 in the first display panel there are contraposition deviation
The upright projection of 100 light-emitting surface is located at the second viewing area AA2 in the upright projection of the light-emitting surface of the first display panel 100,
It effectively solves in display module to exist due to the first display panel 100 and the second display panel 200 when carrying out contraposition fitting pair
The problem that display quality of image is not high, process yields are not high caused by the deviation of position.
In display module made of the production method of the display module provided through this embodiment, the first display panel 100
In, on the direction of the light-emitting surface perpendicular to the first display panel 100, the second viewing area AA2 neutralizes the first viewing area AA1 phase and is overlapped
Folded region is the first sub- viewing area AA21, in the second sub-pixel 210 and the first viewing area AA1 in the first sub- viewing area AA21
The first sub-pixel 110 be arranged in a one-to-one correspondence, i.e., the second sub-pixel 210 and the first viewing area in the first sub- viewing area AA21
The quantity of the first sub-pixel 110 in AA1 is identical, and on the direction of the light-emitting surface perpendicular to the first display panel 100, and first
The second sub-pixel 210 in sub- viewing area AA21 and the first sub-pixel 110 corresponding thereto overlap mutually, in the display stage, control
Make the driving signal and the first display panel of the second sub-pixel 210 in the second display panel 200 in first sub- viewing area AA21
The driving signal of the first sub-pixel 110 in 100 keeps synchronizing, to realize the display of double box liquid crystal display die sets.
On the direction of the light-emitting surface perpendicular to the first display panel 100, the second viewing area AA2 neutralizes the first viewing area
The region that AA1 is not overlapped is the second sub- viewing area AA22, in the display stage, the second sub- viewing area in the second display panel 200
The second sub-pixel 210 in AA22 keeps normally-black display or does not show, so that the display effect of the second sub- viewing area AA22 and the
The observing effect of two non-display area NA2 reaches unanimity, and further increases the display effect of display module.
- Fig. 3, Fig. 6 are continued to refer to figure 1, optionally, wherein Wherein, M be deviation precision, h be the second sub-pixel 210 in a first direction
