Further, the center overlapping of axles of the central axis of through-hole 16 and optical microstructures 211, and the central axis of light source 22 with The center overlapping of axles of through-hole 16.As illustrated in fig. 2 or fig. 5, dotted line indicates the central axis of through-hole, in optical microstructures 211 in figure The central axis of mandrel or light source 22.

In the embodiment of the present application, the central axis of the central axis of light source 22, the central axis of through-hole 16 and optical microstructures 211 It is overlapped, so that light source 22 and optical microstructures 211 are during installation, in this way it is easy to determine whether installation site is correct, improves peace Fill efficiency.

Further, in the embodiment of the present application, the openings of sizes of through-hole 16 is adapted with the size of lens barrel 25, so that light When emitting mould train 1022 is installed in display module 1021, pass through the cooperation of size and 25 size of lens barrel that through-hole 16 is open Position of the light emitting mould group 1022 with respect to display module 1021 is positioned, to improve the installation effectiveness of screen assembly 102.

In other embodiments, lens barrel 25 is equipped with the first label.Display module 1021 is equipped with the second label.First label with Second label cooperation, so that one layer glass substrate 13 of the light source 22 in display module 1021 is completely covered in optical microstructures 211 On projection.That is, in other embodiments, screen assembly 102 in an assembling process, by the first label on lens barrel 25 with The cooperation of the second label in display module 1021, enables light emitting mould group 1022 to be rapidly assembled in display module 1021 On.

Further, referring to Figure 2 together, Fig. 4 and Fig. 6, Fig. 6 be screen assembly 102 shown in Fig. 2 in a second embodiment Structural schematic diagram.The most of technical solution content being identical with the first embodiment in the present embodiment repeats no more.Second implements The difference of example and first embodiment is:

Optical microstructures 211 are set to the second glass substrate 132 towards the surface of light source 22.That is, optical microstructures 211 Between the second glass substrate 132 and light source 22.

In the embodiment of the present application, the stacking of optical microstructures 211 ground is set to table of second glass substrate 132 towards light source 22 Face.At this point, array substrate 14 and display layer 15 in display module 1021 no setting is required through-hole 16, reduces to array substrate 14 And the technique requirement of display layer 15, process flow is reduced, to reduce the production cost of display module 1021.

Further, array substrate 14 and display layer 15 are all made of transparent material.

The region that optical microstructures 211 project in array substrate 14 and display layer 15 is transparent, avoids array base Plate 14 and display layer 15 have blocked the light of the transmitting of light emitting mould group 1022, the light that light emitting mould group 1022 is emitted Through display module 1021, the utilization rate of the light of light emitting mould group 1022 is improved.

The application embodiment is described in detail above, principle of the specific case to the application used herein And embodiment is expounded, the explanation of embodiment of above is merely used to help understand the present processes and its core is thought Think；At the same time, for those skilled in the art, according to the thought of the application, in specific embodiments and applications There will be changes, and to sum up, the contents of this specification should not be construed as limiting the present application.
