Last, the luminous energy for providing display is made of the setting of light source 100 dotted luminescence unit 110, and it is controllable specified
The luminescence unit 110 of position shines.It should be understood that in other embodiments, it can also according to the demand of user, by backlight
100 are set as being made of string light unit.
Further, backlight 100 can periodically be extended.In production or in use, expansion can be set according to demand
Open up backlight 120 (as shown in Figure 4).
In the present embodiment, grating is Lenticular screen 200, and Lenticular screen 200 is arranged before backlight 100, is used for
The light that luminescence unit 110 is emitted on backlight 100 is converged at scattering layer 300.Scattering layer 300 is arranged in cylindrical lens light
Before grid 200, the light come for receiving the convergence of Lenticular screen 200, and forward scatter to any direction.
It should be noted that not limiting here grating, it is possible to understand that, in other specific embodiments,
Grating can be set to slit grating according to the demand of user.
In the present embodiment, two-dimensional projections layer is pinhole array 400, is thrown for will scatter the light come on scattering layer 300
It is mapped to preset direction.When backlight 100 lights a certain luminescence unit 110, the light that luminescence unit 110 is sent out is through cylindrical lens light
Grid 200 pool a series of bright fringes on scattering layer 300, and the bright fringes sequence after pinhole array 400 by being projected onto
Default left and right position.
It should be noted that not limiting here two-dimensional projections layer, it is possible to understand that, in other specific embodiments
In, two-dimensional projections layer can also be set to lens array according to the demand of user.
In the present embodiment, liquid crystal display panel 500 is arranged between scattering layer 300 and pinhole array 400, for providing
Vertical parallax composograph, such as the first anaglyph 510 with up-down directional parallax, the second anaglyph 520, third regard
Difference image 530 and the 4th anaglyph 540.It should be noted that not limiting here the position of liquid crystal display panel 500
It is fixed, it is possible to understand that, in other specific embodiments, the setting of liquid crystal display panel 500 can also be existed according to the demand of user
Other positions before backlight 100, for example, be arranged between backlight 100 and Lenticular screen 200, Lenticular screen 200 with
Between scattering layer 300 or before pinhole array 400.
In the present embodiment, the distance of 100 plane of backlight to Lenticular screen 200 is l1, the coke of Lenticular screen 200
Away from for f1, the distance of Lenticular screen 200 to scattering layer 300 is l2, these parameters meet formula:
l1≥l2 (2)
The 3D display device 010 that the embodiment of the present invention provides, when backlight 100 lights the luminescence unit of different left and right positions
When 110, the variation of 110 position of luminescence unit causes light to converge to the bright wisp formed on scattering layer 300 through Lenticular screen 200
The position of line sequence changes, different to make bright fringes sequence pass through the default left and right position that pinhole array 400 projects.
Specifically, as shown in Fig. 2, when backlight 100 lights the first luminescence unit 111 and sends out the first light 113, the first light 113
The first left and right directions 610 is projected onto after Lenticular screen 200, scattering layer 300 and pinhole array 400;When 100 points of backlight
When bright second luminescence unit 112 sends out the second light 114, the second light 114 is through Lenticular screen 200, scattering layer 300 and pin hole
The second left and right directions 620 is projected onto after array 400.When lighting different luminescence units 110 with chronologically, being time-multiplexed,
Liquid crystal display panel 500 provides corresponding anaglyph, to which the display can be shown on different left and right positions
Different horizontal parallax images.Meanwhile liquid crystal display panel 500 in the up-down direction provide simultaneously it is multigroup with vertical parallax
Composograph, as shown in figure 3, the first anaglyph 510 is projected onto the first upper and lower directions 630 after pinhole array 400, the
Two anaglyphs 520 are projected onto the second upper and lower directions 640 after pinhole array 400, and third anaglyph 530 is through needle passing hole
Third upper and lower directions 650 is projected onto after array 400, the 4th anaglyph 540 is projected onto the 4th after pinhole array 400
Upper and lower directions 660, to form vertical parallax.
To sum up, backlight 100 is lighted the luminescence unit of different location by the 3D display device 010 that the embodiment of the present invention provides
110 several corresponding images with vertical parallax, are shown on different left and right positions, meanwhile, pinhole array 400 will
These composographs with vertical parallax project scheduled upper and lower directions, to be formed simultaneously left and right and vertical parallax.When
When the right and left eyes of viewer are located at corresponding viewpoint, it can be seen that different anaglyph corresponding from viewpoint, to generate
Three-dimensional sense.Since the 3D display device 010 that the embodiment of the present invention provides can carry out the time division multiplexing of pixel in the lateral direction,
Therefore it is compared with traditional grating 3D display device, it can be achieved that high-resolution 3D display, improves image displaying quality.In addition,
