Specific embodiment
The utility model provides a kind of bore hole 3D display device and bore hole 3D gratings.To make the purpose of this utility model, skill
Art scheme and effect are clearer, clear and definite, and the embodiment that develops simultaneously referring to the drawings is further described to the utility model.Should
Work as understanding, specific embodiment described herein is only used to explain the utility model, be not used to limit the utility model.
The bore hole 3D display device that the utility model is provided, it includes display screen and the bore hole being attached on the display screen
3D gratings.When being moved before display screen, because the loop cycle of viewpoint occurs, image occurs jump, to make image smooth eyes,
Jump is not obvious, it is necessary to many using viewpoint, but viewpoint is excessive when can so cause display again, and image resolution ratio is low, therefore selects as follows
The high-resolution display screens of 4K2K, specifically, the display screen is liquid crystal panel, the resolution ratio of the liquid crystal panel for 3840 ×
2160。
Refer to Fig. 1, Fig. 2 and Fig. 3, the bore hole 3D gratings, including substrate 20 and be arranged on the upper table of the substrate 20
The micro-lens arrays layer in face, the micro-lens arrays layer includes the lenticule unit 10 of multiple prism-shapeds, i.e. multiple lenticule lists
Unit 10 arranges to form micro-lens arrays layer in dot matrix；The top of the lenticule unit 10 is sphere.
Because the top of lenticule unit is sphere, there is 360 degree of scopes of sphere light splitting to act on, can by focal plane through spy
The image of different arrangement is regular to be separated, thus observer can around display device 360 degree watch bore hole 3D rendering.
Fig. 4 is referred to, the lenticule unit 10 includes quadrangular portion 120 and is arranged on the top of the quadrangular portion 120
Sphere portion 110.The cross section in the quadrangular portion 120 is rectangle, i.e., the bottom of described lenticule unit 10 is rectangle.Change and
Yan Zhi, four sides of the lenticule unit 10 are plane.The length-width ratio of rectangle is identical with display screen pixel；Such as
This is set, and is conducive to the laminating between lenticule unit 10.Because the pixel of display screen is generally square, therefore the present embodiment
In, the cross section in the quadrangular portion 120 is square.
Further, each lenticule unit 10 covers m × m pixel, and the m is an integer in 4-12.I.e. m takes
Value can be any one integer in 4,5,6,7,8,9,10,11,12, depending on screen resolution and pixel size.This reality
Preferably m is 8 in applying example.Because display screen is generally rectangular, and then the micro-lens arrays layer is rectangle.
Also referring to Fig. 5, the thickness of the substrate d meets equation below：
Wherein, P is the length or width (pixel length and width are equal in the present embodiment) of the pixel of display screen, and S is default for display screen
Sighting distance, W be binocular vision away from (spacing of i.e. two), a is the thickness of display screen upper strata glass substrate.Preferably, described presetting regards
Away from the optimum viewing distance for display screen.The substrate 20 is preferably glass substrate, and in the present embodiment, the substrate 20 is that electron level is saturating
Bright glass.
In the present embodiment, the resolution ratio of display screen is 3840 × 2160, and the optimum viewing distance S of display screen is 1400mm, screen image
Plain size is 0.15525 × 0.15525mm, i.e. P=0.15525mm.W takes 65mm, n1Take 1.5, a and take 0.5mm.
From the similar triangle theory of Fig. 5, P：W=h：S.H=3.343846mm can be tried to achieve.Computing formula herein
Consider the refractive index of substrate, therefore the thickness of h not substrates, the thickness d that calculate substrate also needs to be converted.Consider
There is one layer of glass substrate above liquid crystal panel pixel, from the formula of refractive index, d=h × n1-a.In addition, liquid crystal surface
There are polaroid, glue etc. between plate upper strata glass substrate and substrate, estimate that its thickness is 0.5mm.Therefore in the present embodiment, substrate
20 thickness d=3.343846 × 1.5-0.5-0.5=4.0157693mm.
According to the thickness d of the substrate, grating focal length f=d × k is calculated1, k1It is empirical coefficient.The empirical coefficient k1For
1.1.Then grating focal length f=4.0157693 × 1.1=5.5173459mm.
According to grating focal length f, the radius of curvature of lenticule unit is calculatedIn other words, institute
The radius of curvature R for stating the sphere of lenticule unit meets equation below：
Wherein, n2It is the refractive index of micro-lens arrays layer, 1.56 is taken in the present embodiment.
The computing formula of the radius of curvature R is drawn by the general principle of first-order theory.In the present embodiment, R=
5.5173459/ [1.5/ (1.56-1)]=2.059809mm.
The size (length and width) of thickness d and lenticule unit according to the substrate, calculates lenticule cellular array spacingIn the present embodiment, lenticule unit covering 8 × 8 pixels, i.e. lenticule unit
Width is m × P=8 × 0.15525mm.
Fig. 6, vertex of a triangle behaviour eye source point are referred to, base is the pixel region of lenticule unit covering.By
Similar triangle theory understands that S/ (S+d1)=X/ (m × P), d1 herein does not consider the refractive index of glass, due to lenticule list
The focal length of unit need to be focused in pixel, then from refractive index formula, d1=(f-a)/n1.Thus the battle array of lenticule unit is obtained
Column pitch X=8 × 0.15525 × (1400/ (1400+5/1.5))=1.239mm.
To sum up, optimum viewing distance uses 1400mm, when design thickness of glass substrate is 4mm；The then curvature of lenticule unit half
Footpath R is：2.13248mm, the level interval and vertical interval of each lenticule unit are 1.239mm.
Certainly, it is contemplated that the optimum viewing distance of different product is different, the span of the radius of curvature of the lenticule unit
Can be 1-4mm.The length of side of the lenticule unit can be 1-2mm.
Grating Film (micro-lens arrays layer) is made according to above-mentioned grating parameter, this Grating Film is attached to the thick electron levels of 4mm
On clear glass, i.e. the micro-lens arrays layer is attached on electron level clear glass.Again by this glass and display screen
Opencell glass is close to, display process 360 degree arrangement multi-cams shooting images by specific arrangement, after arrangement
Pattern matrix screen is displayed on the focal plane for reproducing microlens array rear, according to light path principle, by special by rule
The light focusing reduction that the image of different arrangement casts out various image primitives through the lenticule of grating array, so that again
Existing microlens array front reconstructs the 3-D view of object space scene, because image is after being shot through 360 degree of cameras of arrangement
Synthesis, and grating lens unit is circle, therefore can be around 360 degree of viewings of TV during viewing.
It is understood that for those of ordinary skills, can according to the technical solution of the utility model and
The design of its utility model is subject to equivalent or change, and all these changes or replacement should all belong to appended by the utility model
