In some alternative embodiments, please refer to fig. 1, fig. 8 and fig. 9 in combination, in which fig. 8 is another enlarged partial plan view of the control element in fig. 1 (in order to illustrate the structure of the present embodiment, transparency filling is performed in fig. 8), and fig. 9 is a schematic cross-sectional structure in the direction D-D' in fig. 8, in which a forward projection of one collimating hole 301 of the collimating layer 30 to the light-emitting surface of the display panel 20 is located within a range of one sub-pixel 201.
This embodiment explains a case where, among the plurality of collimating holes 301 of the collimating layer 30, at least a part of the number of collimating holes 301 have the following conditions in terms of ensuring transmittance: the size of one collimating hole 301 can be designed to be smaller than one sub-pixel 201 in the orthographic projection to the light-emitting surface of the display panel 20, that is, part of the collimating holes 301 can be designed to be smaller, so that the transmittance can be ensured while each collimating hole 301 of the collimating layer 30 is as small as possible, and further, the color brightness information of only one sub-pixel 201 can be emitted into one light guiding element 101 of the control assembly 10, or further, the chromaticity information of one color sub-pixel 201 in one light guiding element 101 of the control assembly 10 is stronger than that of another color sub-pixel 201, so that the light rays of different color sub-pixels 201 can be further prevented from being absorbed into the same light guiding element 101, the light rays diffused by each sub-pixel 201 of the display panel 20 can be converged through each collimating hole 301 of the collimating layer 30, and the influence of diffused light on the imaging definition of the display screen of the top portion 10A of the control assembly 10 can be better avoided, and further, the display pattern is transmitted to the user more clearly, directly and truly, and the user experience is improved.
In some optional embodiments, please refer to fig. 1-9 and 10 with continuing reference, fig. 10 is a schematic partial structure diagram of the collimating layer, in this embodiment, on a plane parallel to the light emitting surface of the display panel 20, a distance between geometric center points M of two adjacent light guiding elements 101 is S, a distance between geometric center points N of two adjacent collimating holes 301 is L, and L is less than or equal to S.

Optionally, when L2 is greater than L1, if L2 is less than or equal to S, L1 is less than S, so that the effect of converging light rays of the collimating layer 30 can be further improved, and the image sharpness is further improved.

It can be understood that the collimating layer 30 may also be manufactured in the whole manufacturing process of the display panel 20, for example, the collimating layer 30 may be manufactured on one side of the color film substrate 50 away from the array substrate 40 by an evaporation lithography method after the color film substrate 50 is manufactured (as shown in fig. 13), a polarizer (not shown in fig. 13) may also be attached to one side of the collimating layer 30 away from the color film substrate 50 after the collimating layer 30 is manufactured, and finally the glass cover plate 60 is attached to protect the whole display panel 20, so that the collimating layer 30 is as close to each sub-pixel 201 as possible, light rays are converged earlier, and the display definition of the top portion 10A of the control assembly 10 is further improved.

It should be noted that, this embodiment only schematically illustrates that one side of the base 102 close to the display panel 20 is fixedly bonded to the collimating layer 30 through the transparent adhesive 70, but the present invention is not limited to this fixing manner, and other manners that do not affect the emergent light of the display panel 20 and can fix the base 102 of the control component 10 and the display panel 20 may also be used.

The first light-shielding strips 30A and the second light-shielding strips 30B intersect to define the area where the collimating holes 301 are located, so that the collimating layer 30 including the collimating holes 301 can be formed by intersecting the first light-shielding strips 30A and the second light-shielding strips 30B extending in different directions, so that each collimating hole 301 of the collimating layer 30 has a light-shielding performance, and the function of converging light emitted by the display panel 20 is achieved.
Alternatively, as shown in fig. 16, the front projection of the first light-shielding bar 30A to the display panel 20 and the front projection of the second light-shielding bar 30B to the display panel 20 cover the front projection of the black matrix 502 to the light-emitting surface of the display panel 20, that is, the width of the front projection of the first light-shielding bar 30A to the display panel 20 and the width of the front projection of the second light-shielding bar 30B to the display panel 20 may be the same as the width of the front projection of the black matrix 502 to the light-emitting surface of the display panel 20 (not shown), and just the front projection of the first light-shielding bar 30A to the display panel 20 and the front projection of the second light-shielding bar 30B to the display panel 20 cover the front projection of the black matrix 502 to the light-emitting surface of the display panel 20, or the width of the front projection of the first light-shielding bar 30A to the display panel 20 and the front projection of the second light-shielding bar 30B to the display panel 20 may be smaller, so that the collimating layer 30 can function to converge light while avoiding the influence on the display aperture ratio. Optionally, when the transmittance allows, the width of the forward projection of the first light-shielding bar 30A to the display panel 20 and the width of the forward projection of the second light-shielding bar 30B to the display panel 20 may be greater than the width of the forward projection of the black matrix 502 to the light-emitting surface of the display panel 20 (as shown in fig. 16), so as to further increase the effect of the collimating layer 30 on converging the light emitted from the display panel 20.

In the embodiment, the black matrix 502 inside the display panel 20 is multiplexed as the collimating layer 30, which is beneficial to the thin design of the display device 000, and the display image definition of the top 10A of the control assembly 10 of the display device 000 can be improved by the converging light of the collimating layer 30, so as to improve the display quality.
In some alternative embodiments, please continue to refer to fig. 1-2 and 17, in the present embodiment, the height of the collimating layer 30 along the direction Z perpendicular to the light-emitting surface of the display panel 20 is in a range of 40-60 μm.

Although the higher the height of the collimating layer 30 is, the better the effect of the collimating holes 301 for converging the outgoing light of the display panel 20 is, because the thickness range that can be set without affecting the display function of the color resists 503 is considered for the whole thickness of the display panel 20 and the OC protective layer, the height range of the collimating layer 30 is set along the direction Z perpendicular to the light outgoing surface of the display panel 20 and is 40-60 μm in the present embodiment, so that the outgoing light of the display panel 20 can be converged well, and the thickness of the panel can be controlled within a small range, which is beneficial for the thinning development of the display panel 20 and the whole display device 000.
