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 attached
Figure and specific embodiment are described in detail.
Present invention firstly provides a kind of virtual reality display module, as shown in Figure 1A, including display floater 101
With the microlens layer 102 being positioned at described display floater 101 light emission side；
Described display floater 101 includes multiple pixel cell, and each pixel cell is by multiple sub-pixs 1011
Constitute；
Described microlens layer 102 includes multiple lenticule unit 1021, and each lenticule unit 1021 is corresponding
Part sub-pix on display floater 101；The sub-pix 1011 of each lenticule unit 1021 correspondence exists
Imaging in the region of lenticule unit 1021 correspondence, and constituted display picture by the imaging of all sub-pixs 1011
Face.
From the above it can be seen that the microlens layer that the virtual reality display module of the present invention is used includes
Multiple lenticule unit, each lenticule unit corresponding part sub-pix rather than one single lens of employing
Corresponding all of sub-pix, and use these single lens that the display picture of all sub-pixs is carried out imaging,
Be equivalent to the independent lens by virtual reality display module in prior art is used and be divided at least two portion
Point, the quality summation of all lenticule unit is less than single lens, thus the present invention can alleviate
The weight of mirror part, thus reduce the weight of whole virtual display display module.And each lenticule with
Distance between display floater is less than the single lens distance to display floater such that it is able to reduce whole
The size of virtual display display module.
In the specific embodiment of the invention, described lenticule unit be lens used in the prior art etc.
Scale smaller body.
Those skilled in the art should learn, is provided with the basic structure of necessity between described sub-pix,
Such as black matrix etc..Can be provided with interval between described lenticule unit, interval is fitted mutually with black matrix size
Should.
In some embodiments of the invention, referring still to Figure 1A, each lenticule unit 1021 and an Asia
Pixel 1011 is correspondingly arranged.Therefore, microlens layer 102 includes the lenticule unit 1021 of multiple array arrangement,
The integral thickness of microlens layer 102 is less than lens of the prior art, and area coverage is constant, thus weight fall
Low, thus the overall weight of whole virtual reality display module reduces.
In some embodiments of the invention, referring still to Figure 1B, each sub-pix 1011 includes sub-pix master
Body 1012 and at least one sub-pix micro structure 1013, described sub-pix micro structure 1013 is positioned at sub-pix
Between the sub-pix main body 1012 of main body 1012 and neighboring sub-pixel, and described sub-pix micro structure 1013
Color identical with the color of the sub-pix main body of neighboring sub-pixel.
In the specific embodiment of the invention, on the array base palte of described display floater and color membrane substrates at institute's division
Sub-pix all include sub-pix main body and sub-pix micro structure, meanwhile, sub-pix main body and the micro-knot of sub-pix
Structure can be separated by black matrix.
Lenticule cell imaging principle is identical with ordinary lens, as it is shown in figure 5, according to computing formula,
Wherein, l is image distance, and l is object distance, and f ' is the focal length of lens；Can draw amplification:
Owing to the microlens layer of the embodiment of the present invention includes at least two lenticule unit, use existing display
Pixel designs, and directly plus lenticule imaging, picture can be amplified, can directly contribute picture by each lenticule
Between element, the problem of imaging ghost image, causes colour mixture, has a strong impact on display effect.With reference to Fig. 2, actually used
Time, along with the minimizing of sub-pix 1011 number of lenticule unit 1021 correspondence, at different lenticule unit
The imaging 1022 of 1021 there will be ghost image, thus the sub-pix of the embodiment of the present invention uses above-mentioned sub-pix master
The structure that body and sub-pix micro structure combine, thus ghost image can be eliminated when actually used.By above-mentioned reality
Execute example, mate lenticule imaging contexts, carried out the design of corresponding pixel, ghost image can have been eliminated, reach relatively
Good display effect.In order to the most preferably be embodied as the ghost image of picture, by the imaging of neighboring sub-pixel respectively
Draw at distance lenticule unit different distance.
In some embodiments of the invention, with reference to Fig. 3 A, described display floater includes arranged in arrays many
Individual sub-pix 301, then sub-pixel structure is with reference to Fig. 3 B, and each sub-pix 301 includes sub-pix main body
3011 and be positioned at the sub-pix micro structure 3012 of two long sides of described sub-pix main body 3011, sub-pix
Isometric with described sub-pix main body 3011 and with described sub-pix main body 3011 the long limit of micro structure 3012 is put down
OK.
In most of the cases, for showing that the pixel arrangement of 3D picture includes array arrangement or Delta row
Mode for cloth, the sub-pixel structure that the embodiment of the present invention is provided is applied to the display floater that pixel is arranged in array
When neutralization is applied in the display floater that pixel is Delta arrangement, structure is otherwise varied.
In some embodiments of the invention, with reference to Fig. 4 A, described display floater includes multirow sub-pix 401,
Adjacent lines or adjacent column sub-pix 401 are staggered.Sub-pixel structure as shown in Figure 4 B, each sub-pix
401 include sub-pix main body 4011 and are arranged at the Asia picture of four avris of described sub-pix main body 4011
Element micro structure 4012, the limit that described sub-pix micro structure 4012 is corresponding with described sub-pix main body 4011
Parallel.According to the concrete arrangement mode of sub-pix, the length of sub-pix micro structure 4012 is put down less than with it
The corresponding limit of sub-pix main body of row.
In some embodiments of the invention, with reference to shown in Fig. 6, when sub-pix includes sub-pix main body and sub-picture
During element micro structure, described display floater also includes:
AND circuit 701 between adjacent two sub-pixs, two inputs of described AND circuit are respectively
Connect TFT switch 703 drain electrode of described two adjacent sub-pix main body 702 correspondences, described and door

It is thus possible to realize sub-pix main body 702 and the driving of sub-pix micro structure 704.
When driving, when only neighboring sub-pixel main body is lighted simultaneously, between the two neighboring sub-pixel main body
Sub-pix micro structure just can light.Control the way lighted of sub-pix micro structure need to introduce with door and
The control unit of MOS, in pixel arrangement as shown in Figure 4 B, when red sub-pixel main body 4011 and green
When color sub-pix main body 4011 is lighted simultaneously, the red sub-pixel micro structure 4012 in the middle of it and green Asia picture
Element micro structure 4012 is lighted the most simultaneously, uses the drain electrode of two pixels to add and door control unit during control,
When both light simultaneously, there is signal with door, signal introduced two alternate sub-pixels, lights two sub-pixels,
Thus realize the control of sub-pixel.
When the sub-pix of display floater arranges according to the mode of array arrangement, type of drive arranges with Delta
Sub-pix type of drive be similar to.
