Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
For existing display device cannot to stravismus time the problem of higher-quality display picture is provided, the present invention provides one
Plant solution.
On the one hand, embodiments of the invention provide one display structure, as it is shown in figure 1, include:
Display module 1；
It is arranged on the vision conversion film 2 of display module 1 light emission side；
Wherein, above-mentioned vision conversion film 2 has multiple micro unit 21, and the emergent ray of display module 1 enters each micro-list
Reflect after unit 21, and along preset direction outgoing micro unit 21.
In actual applications, the micro unit 21 of the present embodiment can be evenly distributed on the exiting surface of display module so that
Emergent ray can point to user's side position of stravismus display structure evenly along preset direction, thus ensures that user can see
See the display picture of bigger brightness, and then improve the Consumer's Experience of display product.
Below in conjunction with an actual application, the vision of the present embodiment is changed film to be introduced.
Exemplarily, as in figure 2 it is shown, the vision conversion film of the present embodiment includes: substrate 22 and being formed in this substrate 22
Micro unit 21.
Wherein, as exemplary introduction, the micro unit indentation structure of the present embodiment, it is clear that this laciniation is permissible
Emergent ray is made to reflect to side (i.e. preset direction).
Specifically, in the application of this reality, laciniation is asymmetric structure, and one of them side is formed with base
Interior angle is towards preset direction, and the internal angle beta formed with base less than another side.
Structure based on above-mentioned laciniation designs, and reflects with further reference to the light shown in Fig. 3, when emergent ray is worn
After crossing laciniation, light can be more concentrated at being reflected by the side corresponding to less interior angle so that preset direction is towards relatively
Little interior angle.
Obviously, according to above-mentioned refraction principle, the emergent ray of the present embodiment should reflect to predetermined angle more,
Therefore by rationally arranging the size of the interior angle of laciniation, can control to show the direction of the emergent ray of structure flexibly.
In actual applications, it is assumed that preset direction towards the viewing location of user, then arranges interior angle according to the viewing location of user
Size.
Specifically, as a feasible embodiment, the tooth depth of the laciniation in the present embodiment is 20um-
22um, tooth bottom width degree is 20um-21um, and the thickness of substrate is 10um-10.5um.
Design based on above-mentioned vision conversion film, the present embodiment can be disposed at going out of the light guide plate in display structure
Light side, as exemplary introduction, as shown in Figure 4, the display structure of the present embodiment specifically includes that
LED light source 41, light guide plate 42, lower diffusion barrier 43, prism 44 and vision conversion film 45.
Wherein, the light of LED light source 41 is after light guide plate 42, through lower diffusion barrier 43, the effect of lower diffusion barrier 43 be by
The uniform light of LED light source 41 is projected to prism 44, and prism 44 is the light luminance for improving LED light source 41 so that LED light
The light in source 41 reflects along preset direction after eventually passing through vision conversion film 45.
Additionally, embodiments of the invention vision can also be changed film be arranged on display structure in display floater go out light
Side, owing to principle is identical, the most no longer carries out citing and repeats.
In sum, design based on the present embodiment, divide with reference to the heat operationally of the display structure shown in Fig. 6
Butut, as can be seen from Figure 8, the light of display picture can be along a preset direction outgoing so that heat concentrates on screen
A region in.
On the other hand, the present invention also provides for the manufacture method of a kind of above-mentioned vision conversion film, including:
Step one, forms photoresist layer；
Step 2, uses mask plate to be exposed photoresist layer, develop, and the photoresist layer making photoresist remove district is carved
Eating away, obtains the micro unit formed by remaining photoresist layer.
Below in conjunction with the flow process of a concrete making vision conversion film, the manufacture method of the present embodiment is introduced.
The manufacture method of the present embodiment specifically includes:
Step S1, with reference to Fig. 5 A, in the light emission side 51 of display floater or light guide plate, deposits one layer of resin composite materials, should
Resin composite materials is i.e. as the substrate layer 52 forming micro unit；
Step S2, with reference to Fig. 5 B, coats photoresist layer 53 on substrate layer 52；
Step S3, with reference to Fig. 5 C, uses mask plate 6 that photoresist layer 53 is exposed, is developed, makes photoresist remove district
Photoresist layer 53 is etched away, and finally gives micro unit 53 ＇ formed by remaining photoresist layer as shown in Figure 5 D；
Specifically, in this step, above-mentioned mask plate 6 includes: substrate 61 is multiple light tight be formed in substrate 61
Grid 62, each grid 62 has the cross section vertical with the plane of substrate 61.Two sides of such as this cross section not with
The plane of substrate 61 is vertical, and cross section is the parallelogram at certain angle of inclination.Structure based on this grid 62 designs, exposure
During light irradiating angle as shown in Figure 6, by transmission region light irradiate photoresist 43 indentation structure, and saw
Two interior angle of dentalation and β have different angles, and the side corresponding to interior angle that wherein angle is less is for by outgoing
Light is concentrated and is refracted on preset direction.
More than being merely cited for property introduce the present embodiment vision conversion film manufacture method.As other schemes, this reality
Execute the grid of example be perpendicular to the cross section of substrate can also rectangle or trapezoidal.Wherein, if as it is shown in fig. 7, the grid 62 of mask plate
Cross section be rectangle, two interior angle of the laciniation of the most illuminated photoresist 43 and the angle of β are identical in theory
, i.e. show that the situation that the emergent ray of structure finally reflects to both sides is also identical, do not concentrate deflection preset direction.
And the grid using cross section to be trapezoidal cross-section, then deposit in the making of grid and the interior angle size of control zigzag structure
In difficulty, it is difficult to implement.
The cross section of this grid can be the parallelogram in certain angle of inclination, is used for forming asymmetric zigzag
Structure, the cross section of this grid can be rectangle, forms symmetrical expression laciniation.
Visible, the present embodiment manufacture method structure based on above-mentioned mask plate designs, it is only necessary to be exposed photoresist
Development just can produce the micro unit of laciniation, and the refractive direction of micro unit also is able to structure based on mask plate and obtains
Accurately control, owing to whole method is implemented simple, therefore there is the highest practical value.
In the present embodiment, it should be appreciated that the size of the sequence number of above-mentioned each process is not meant to the priority of execution sequence, respectively
The execution sequence of process should determine with its function and internal logic, and should not constitute any to the implementation process of the embodiment of the present invention
Limit.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, it is also possible to make some improvements and modifications, these improvements and modifications are also
Should be regarded as protection scope of the present invention.
