Embodiment
Below in conjunction with specific embodiment, so that the present invention is described in further detail.
Refer to Fig. 1, the embodiment of the present invention provides a kind of display device 100, and it comprises a projecting cell 10, rotary unit 40, multiple reflector element 50 and a screen unit 60.
This projecting cell 10 comprises a body 20, first projection lens 30 and second projection lens 32.Particularly, this body 20 is a hollow housing, and it has a cylindrical shape outline, on the peripheral sidewall 200 that this first projection lens 30 and this second projection lens 32 are arranged on this body 20 and partial receipt in this body 20.This first, second projection lens 30,32 can comprise a lens barrel 34 respectively and be housed at least one eyeglass 36 in this lens barrel 34.In the present embodiment, the eyeglass 36 of this first projection lens 30 is coaxial with the eyeglass 36 of this second projection lens 32, and the line of centres of this first projection lens 30,32, also namely the optical axial of eyeglass 36 and the central shaft of this body 20 perpendicular.Change in embodiment at other, this projecting cell 10 only can comprise first projection lens 30 (or second projection lens 32), also can comprise multiple projection lens further, as four projection lens evenly arranged along a circumferencial direction, be not limited to specific embodiment.
This rotary unit 40 rotates around a turning axle M for driving this first, second projection lens 30,32.In the present embodiment, this rotary unit 40 can be a rotation motor assembly, and it is mechanically coupled to the body 20 of this projecting cell 10.This rotary unit 40 drives this first, second projection lens 30,32 High Rotation Speed by rotating this body 20, and such as, the gyro frequency being more than or equal to 60 times with bell per second rotates.Central shaft and its turning axle M of this body 20 coincide.Change in embodiment at other, this rotary unit 40 also can be other rotary components, as revolving cylinder assembly etc.
Please also refer to Fig. 2 and Fig. 3, the plurality of reflector element 50 is evenly arranged around this turning axle M.In the present embodiment, the number of the plurality of reflector element 50 is specially four, and the central distribution of these four reflector elements 50 is in the same plane perpendicular with this turning axle M.Each reflector element 50 is a square platy structure, and it has the reflecting surface 500 of this projecting cell 10 relative.This reflecting surface 500 is square plane, and its relative this turning axle M tilts, and four reflectings surface are identical with angle of inclination relative to the vergence direction of turning axle M, as shown in Figure 3.
In the present embodiment, this screen unit 60 is square cone, it comprises bottom surface 600 and four screens 602 one by one, wherein, central shaft (not shown) and this turning axle M of this rectangular pyramid coincide, this bottom surface 600 is positioned at the side of this square cone away from this projecting cell 10, these four screens 602 are respectively four sides of this square cone, and this four screens 602 are connected with this bottom surface 600 respectively around this bottom surface 600, relative this turning axle M of each screen 602 tilts, as shown in Figure 3.
These four screens 602 are corresponding with these four reflectings surface 500 respectively.During work, this first, second projection lens 30,32 projects light (this light corresponds to same image) along two directions mutually deviated from of its line of centres.This rotary unit 40 drives this first, second projection lens 30,32 High Rotation Speed.These four reflectings surface 500 sequentially reflect light that this first, second projection lens 30,32 projects on the screen 602 corresponding with it, and these four screens 602 reflect light towards all directions around this screen unit 60.Due to the eye storage characteristic of human eye, when first, second projection lens 30,32 High Rotation Speed, observer can be watched first, second projection lens 30,32 to project image by different angles, thus the needs meeting observer's motion direction when watching image.Such as, as shown in Figure 2, when on the bearing of trend that observer N is positioned at two adjacent and crossing screens 602, its image observed be by these two screens 602 reflect and enter the image of right and left eyes respectively.As shown in Figure 3, when observer N is just to any one screen 602, its image observed is the image reflected by this screen 602.
Be understandable that, this display device 100 also can have other and change embodiment, and such as, this screen unit 60 can have other shape, as pentagonal pyramid body, hexagonal pyramid body or prism etc.The number of this reflector element 50 should be equal with the side of this screen unit 60, such as, when this screen unit 60 is pentagonal pyramid, the number of this reflector element 50 correspondence can be set to five, and the reflecting surface 500 of these five reflector elements 50 is relative with five sides of this screen unit 60 respectively.Certainly, the number of this reflector element 50 also can not be equal with the side number of this screen unit 60, as long as can ensure that observer all can see image in each orientation around this screen unit 60, is not limited to specific embodiment.In addition, the reflecting surface 500 of this reflector element 50 is also not limited to the square shown by the present embodiment, it also can be other shape, as circular, oval etc., as long as light that first, second projection lens 30,32 projects can be reflected on screen 602, and make the light that screen 602 reflects enter human eye, thus make human eye can observe complete image, be not limited to specific embodiment.
It is noted that above-mentioned embodiment is only better embodiment of the present invention, those skilled in the art also can do other change in spirit of the present invention.These changes done according to the present invention's spirit, all should be included within the present invention's scope required for protection.
