Abstract

The invention discloses a bare three-dimensional splicing display unit. The bare three-dimensional splicing display unit comprises a support frame; a bare three-dimensional back projection screen fixed at one end of the support frame; and at least a projector for projecting an image to the bare three-dimensional back projection screen. The invention further discloses a bare three-dimensional splicing display device which comprises a plurality of bare three-dimensional splicing display units arranged in an M*N array, wherein M and N are integers greater than 1. With the adoption of the technical scheme, bare three-dimensional image display with large picture and high resolution can be realized.

Description

Naked display unit and the splicing display device thereof looked 3 D spliced
Technical field
The present invention relates to a kind of naked display unit and splicing display device thereof looked 3 D spliced.
Background technology
At present, watch the dynamic solid image to wear glasses and the naked dual mode of looking.Because wearing spectacles has inconvenience, therefore, it is the focus that those skilled in the art pay close attention to that naked parallax stereogram picture shows always.But, in the prior art, also do not solve the scheme that the dynamic naked parallax stereogram picture of big picture shows.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of naked display unit and splicing display device thereof looked 3 D spliced that is used to realize the naked parallax stereogram picture demonstration of big picture.
The technical scheme that the present invention adopted is: a kind of naked display unit of looking 3 D spliced comprises: bracing frame; Nakedly look three-dimensional rear projection screen, be fixed in an end of bracing frame; At least one projector is used for image projection is looked three-dimensional rear projection screen to naked.
The invention also discloses a kind of naked display device of looking 3 D spliced, comprise a plurality of naked display units of looking 3 D spliced, these are a plurality of nakedly looks 3 D spliced display unit and is arranged in M * N array, and wherein, M and N are the integer greater than 1.
After adopting technique scheme; Each is naked looks 3 D spliced the demonstration that display unit can be realized dynamic naked parallax stereogram picture; When nakedly looking 3 D spliced display unit combination (like the capable N row of M) and become the naked display device of looking 3 D spliced, can realize that giant-screen is dynamically naked to look stereoscopic picture plane and show with a plurality of.In addition, of the present inventionly nakedly look 3 D spliced the mode that display unit can pile up and form array, thereby realized quick assembly and disassembly.

Embodiment
Below in conjunction with accompanying drawing the present invention is made further explanation.
With reference to figure 1.Nakedly according to an embodiment of the invention look 3 D spliced display unit and comprise bracing frame 1, naked rear projection screen 2 and at least one projector 3 of looking three-dimensional.Nakedly look three-dimensional the end that rear projection screen 2 is fixed in bracing frame 1, at least one projector 3 is used for image projection is looked three-dimensional rear projection screen 2 to naked.
Preferably, bracing frame 1 is a casing.Adopt casing can effectively intercept the interference of external environment light, thereby improve image quality.
Nakedly look three-dimensional rear projection screen 2 and is made up of with imaging film 22 the naked stereoscopic screen 21 looked, imaging film 22 is covered in the naked back side of looking stereoscopic screen 21, is used to realize that back projection forms images.The naked stereoscopic screen 21 of looking can be tabular or membrane structure, and it can be the naked stereoscopic screen of looking of column mirror grating type, also can be the naked stereoscopic screen of looking of slit grating type.For the ease of realizing a plurality of naked screen splicings of looking 3 D spliced display unit are become giant-screen, naked shape of looking stereoscopic screen is preferably rectangle.
In embodiment shown in Figure 1, rear projection screen 2 is directly looked three-dimensional towards naked by projector 3.In another embodiment illustrated in fig. 2, projector 3 is arranged on the below of catoptron 4, and the ray cast of projector 3 reflexes on the screen through catoptron 4 to catoptron 4.Each naked projector of looking 3 D spliced display unit can be fixed on the bracing frame of this unit, also can be fixed on the bracing frame of adjacent cells.
Above-mentioned nakedly look 3 D spliced display unit and combine a plurality of, just can constitute the naked display device of looking 3 D spliced of the present invention, as shown in Figure 6.Wherein, a plurality ofly nakedly look 3 D spliced display unit 100 and be arranged in M * N array; M and N are the integer greater than 1.These are a plurality of nakedly looks 3 D spliced display unit 100 and can form array through the mode of simply piling up, thereby can realize quick assembly and disassembly.
Because naked singularity of looking 3D, the resolution of image is high more good more.In order to obtain higher image resolution ratio, naked looking 3 D spliced in the display unit as shown in Figure 3 is provided with many projectors 3.These many projectors arrange with M * N array way; Wherein, M is a line number, and N is a columns, and M and N are the integer greater than 1.If single naked projector's quantity of looking 3 D spliced in the display unit increases, then each naked resolution of looking 3 D spliced display unit itself is just very high.Look 3 D spliced display unit than projector's negligible amounts naked, under the prerequisite that obtains same image resolution ratio effect, form naked naked quantity of looking 3 D spliced display unit of looking 3 D spliced display device and just can reduce.In conjunction with Fig. 4 and shown in Figure 5; In order to separate the light between each projector 3; Make the image of each projector 3 be able to intact splicing; In naked the place ahead of looking the projecting plane of three-dimensional rear projection screen grid 5 can also be set, a plurality of grate openings 51 of grid 5 are corresponding one by one with many projectors of this M * N projector array.
Of the present inventionly nakedly look 3 D spliced display device and can realize big picture, the high-resolution naked stereo display effect of looking.
