Specific implementation mode
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
Present invention firstly provides a kind of virtual reality display modules, as shown in Figure 1A, including display panel 101 and be located at institute
State the microlens layer 102 of 101 light emission side of display panel；
The display panel 101 includes multiple pixel units, and each pixel unit is made of multiple sub-pixes 1011；
The microlens layer 102 includes multiple lenticule units 1021, and each lenticule unit 1021 corresponds to display surface
Part sub-pix on plate 101；Each lenticule 1021 corresponding sub-pixes 1011 of unit are corresponding in lenticule unit 1021
It is imaged in region, and display picture is constituted by the imaging of all sub-pixes 1011.
From the above it can be seen that microlens layer used by the virtual reality display module of the present invention includes multiple micro-
Lens unit, each lenticule unit corresponding part sub-pix rather than correspond to all sub- pictures using an individual lens
Element, and the display picture of all sub-pixes is imaged using the individual lens, being equivalent to will be virtual existing in the prior art
Independent lens used by real display module have been divided at least two parts, and the quality summation of all lenticule units is less than individually
A lens, to which the present invention can mitigate the weight of lens component, to reduce entire virtual display display module
Weight.And each the distance between lenticule and display panel are less than at a distance from individual lens to display panel, to
The size of entire virtual display display module can be reduced.
In the specific embodiment of the invention, the lenticule unit is that the equal proportion of lens used in the prior art contracts
Corpusculum.
Those skilled in the art should can learn, necessary basic structure is provided between the sub-pix, such as
Black matrix etc..Interval can be provided between the lenticule unit, interval is adapted with black matrix size.
In some embodiment of the invention, referring still to Figure 1A, each lenticule unit 1021 and a sub-pix 1011
It is correspondingly arranged.Therefore, microlens layer 102 includes the lenticule unit 1021 of multiple array arrangements, the whole thickness of microlens layer 102
Degree is less than lens in the prior art, and area coverage is constant, thus weight reduces, so that entire virtual reality display module is whole
Body weight reduces.
In some embodiment of the invention, referring still to Figure 1B, each sub-pix 1011 includes 1012 He of sub-pix main body
At least one sub-pix micro-structure 1013, the sub-pix micro-structure 1013 are located at sub-pix main body 1012 and neighboring sub-pixel
Between sub-pix main body 1012, and the color of the sub-pix main body of the color and neighboring sub-pixel of the sub-pix micro-structure 1013
It is identical.
In the specific embodiment of the invention, the sub- picture in the array substrate and color membrane substrates of the display panel at institute's division
Element includes sub-pix main body and sub-pix micro-structure, meanwhile, sub-pix main body and sub-pix micro-structure can by black matrix into
Row separates.
Lenticule cell imaging principle is identical as ordinary lens, as shown in figure 5, according to calculation formula,
Wherein, l is image distance, and l is object distance, and f ' is the focal length of lens；It can obtain amplification factor：
Since the microlens layer of the embodiment of the present invention includes at least two lenticule units, set using existing display pixel
Meter directly adds lenticule and is imaged, and each lenticule can amplify picture, can directly contribute and be imaged asking for ghost image between pixel
Topic, causes colour mixture, seriously affects display effect.With reference to Fig. 2, in actual use, with 1021 corresponding Asia of lenticule unit
The reduction of 1011 numbers of pixel will appear ghost image, thus the embodiment of the present invention in the imaging 1022 of different lenticule units 1021
The structure that is combined using above-mentioned sub-pix main body and sub-pix micro-structure of sub-pix, to which weight can be eliminated in actual use
Shadow.By above-described embodiment, match lenticule imaging contexts, carried out corresponding pixel design, ghost image can be eliminated, reach compared with
Good display effect.In order to preferably embody the ghost image of imaging in figure, by the imaging of neighboring sub-pixel respectively apart from micro-
It is drawn at mirror unit different distance.
In some embodiment of the invention, with reference to Fig. 3 A, the display panel includes multiple sub-pixes arranged in arrays
301, then sub-pixel structure is with reference to Fig. 3 B, each sub-pix 301 is including sub-pix main body 3011 and is located at the sub-pix master
The sub-pix micro-structure 3012 of two long sides of body 3011, sub-pix micro-structure 3012 and the sub-pix main body 3011 are isometric
And it is parallel with the long side of the sub-pix main body 3011.
In most cases, for showing that the pixel arrangement of 3D pictures includes array arrangement or Delta arrangement mode,
The sub-pixel structure that the embodiment of the present invention is provided is applied to the display panel neutralization that pixel is arranged in array
When in the display panel of Delta arrangement, structure different from.
In some embodiment of the invention, with reference to Fig. 4 A, the display panel includes multirow sub-pix 401, adjacent rows or
Adjacent column sub-pix 401 is staggered.Sub-pixel structure is as shown in Figure 4 B, and each sub-pix 401 includes sub-pix main body 4011
And it is set to the sub-pix micro-structure 4012 of four avris of the sub-pix main body 4011, the sub-pix micro-structure 4012
It is parallel with the corresponding side of the sub-pix main body 4011.According to the specific arrangement mode of sub-pix, sub-pix micro-structure 4012
Of length no more than corresponding side of sub-pix main body in parallel.
In some embodiment of the invention, with reference to shown in Fig. 6, when sub-pix includes sub-pix main body and sub-pix micro-structure
When, the display panel further includes：
Two input terminals of the AND gate circuit 701 between adjacent two sub-pix, the AND gate circuit are separately connected institute
State two adjacent 702 corresponding TFT switch of sub-pix main body, 703 drain electrodes, the output end of the AND gate circuit 701 with it is adjacent
Sub-pix micro-structure 704 between two sub-pix main bodys 702 connects, so as to realize to sub-pix main body 702 and sub- picture
The driving of plain micro-structure 704.
In driving, when only neighboring sub-pixel main body is lighted simultaneously, the sub- picture between the two neighboring sub-pixel main bodys
Plain micro-structure can just be lighted.The method that control sub-pix micro-structure is lighted needs to introduce the control unit with door and MOS, such as Fig. 4 B
