Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
In order to overcome in the prior art of Fig. 1 .a and Fig. 1 .b, there is viewing dead band 300, can only realize the defect of seamless spliced effect in front, the present invention adopts the mode increasing optical sheet viewing sight line to be reconfigured, and makes can realize seamless spliced effect in all angles.
As Fig. 2 .a and 2.b is depicted as the first embodiment of the present invention, the center section of display screen 101 is viewing area 103 in the present embodiment, and marginal portion is frame 102.Above frame 102, be provided with compensation display device, be used for compensating the display section blocked because of frame 102.In the present embodiment, compensation display device is LED component, specifically comprises for the pcb board 201 of control LED202 and the protective cover for the protection of LED202.Such as, it is to be appreciated that for the compensation display device of other types, OLED or small-sized LCD panel are applicable in the present invention too.Concrete, the LED202 that the compensation display device in the present embodiment comprises the pcb board 201 be sticked on frame, is electrically connected with pcb board, covers the protective cover 203 outside LED202.
Above viewing area 103, be provided with optical sheet 400, optical sheet 400 is a transparent plate in the present embodiment, and its size is less than or equal to viewing area 103, and end face, for facing directly and in advance this end face being carried out optical coating, is become reflecting surface 401.Reflecting surface 401 is pressed close to or is bonded in the side of protective cover 203.
Again with one at least in one direction size be greater than optical component hyaline membrane paste 402 zone line and optical sheet 400 fit, the zone line that hyaline membrane pastes 402 first fit with the exiting surface of optical sheet 400 or bonding, fringe region after bending and the side bonds of display screen 101 fix.The viewing effect at its angle of inclination is as shown in Fig. 2 .b, and the sight line originally dropping on viewing dead band is adjusted by reflecting surface 401, drops on viewing area 101, also can obtain seamless spliced effect like this on pitch angle.
Be illustrated in figure 3 the second embodiment of the present invention; in the present embodiment; optical sheet 400 have employed different structures: the marginal portion of optical sheet 400 processes a width and the L v notch v compensating display device width and mate; being placed in compensating display device among the space that L v notch v and display screen frame formed, cancelling the protective cover 203 in the first embodiment.The present embodiment is not owing to carrying out bonding by compensation display device with optical sheet 400, the facing directly of L v notch v of optical sheet 400 directly forms fully reflecting surface in air dielectric, its optical effect is identical with the reflecting surface formed through optical coating in the first embodiment, therefore, the present embodiment can realize and the identical optical effect of the first embodiment, realize showing at the Rimless of any viewing angle, and fabrication and installation technique is simpler than the first embodiment.
As Fig. 4 .a and Fig. 4 .b is depicted as the third embodiment of the present invention, the present embodiment is an improvement based on the second embodiment, owing to compensating the LED that display device adopts brightness higher, and display screen 101 liquid crystal board that normally brightness is lower, both have obvious difference in brightness, adjust be difficult to both brightness regulation to consistent by means of only electronics mode.In order to this is obviously distinguished elimination, the exiting surface of LED installs one piece of optical attenuation sheet 500 additional, the concrete structure of optical attenuation sheet 500 is as shown in Fig. 4 .b.The surface of light decay sheet is arranged alternately the photic zone 502 and light tight district 501 that are parallel to each other, this array pattern can adopt on inkjet printing to transparent sheet and make, again the optical attenuation sheet 500 made is pasted in the plane of the L v notch v of optical sheet corresponding to the luminous place of LED, suitable technique also directly can be adopted on this plane to stamp designed array pattern and form optical attenuation face.
And consider lambert's characteristics of luminescence of LED and the non-lambertian characteristics of luminescence of LCD panel, different angles is watched, the consistent object of all angles viewing effect can't be met very well by the mode of the LED luminance that simply decays.For this reason, in the fourth embodiment of the present invention, the exiting surface of LED installs one piece of micro-optic sheet 600 additional, the surface of micro-optic sheet 600 is provided with microlens array, microtrabeculae lens array or microprism array or atomization surface, as shown in Figure 5.By adjusting the parameter on its surface, obtain the consistent effect of brightness in all angles.When concrete enforcement time, can by transparent smooth optical sheet, by the method for chemical agent or Physical Processing, the surface of transparent optical sheet is made to become coarse, make transparent smooth optical sheet become the micro-optic sheet 600 meeting our needs, make the attenuation degree of all angles consistent; Also the mode such as or injection mo(u)lding shaping by direct die press directly makes the micro-optic sheet 600 with microlens array, microtrabeculae lens array or microprism array, and concrete array parameter can adjust flexibly according to the size of actual product, the brightness etc. that compensates display device.
Be illustrated in figure 6 the fifth embodiment of the present invention, in the present embodiment, the breach of optical sheet 400 forges into C shape, and the vertical plane of C v notch v is plated to reflecting surface 401, then compensation display device is placed in close plane place, top in this C v notch v and fixes with the embedding of transparent Embedding Material 204.Fixed by embedding; compensate display device and will form one with optical sheet 400; do like this and be conducive to the producer and carry out production assembling, simultaneously transparent Embedding Material adopts the optical cement with higher clarity and solidification intensity, makes to compensate display device and is effectively protected.On the lower surface compensating display device and C v notch v, leave gap, this gap is applicable to the Angle connection sheet 700 inserting L shape, and the relative position between display screen 101 and optical sheet 400 is fixed.The Angle connection sheet 700 of L shape has two planes in 90 °, and one of them plane is inserted into the gap on the lower surface compensating display device and C v notch v, and further bonds together; Another plane then with the side fixed bonding of display screen 101.By the Angle connection sheet 700 of L shape, intensity and the steadiness of whole display device can be improved.
If Fig. 7 is the sixth embodiment of the present invention.Because the optical sheet 400 in a upper embodiment is C v notch v, such breach is applicable to the Angle connection sheet installing L shape additional.And when the breach of optical sheet 400 is L shapes, then change over structure as shown in Figure 7.The vertical plane of L v notch v is plated to reflecting surface 401, again compensation display device be placed in close plane place, top in this L v notch v and fix with the embedding of transparent Embedding Material 204, compensation display device and optical sheet 400 is made to be connected into optical component, must ensure when carrying out embedding with transparent Embedding Material 204 to add formation vertical plane in the outer rim of optical sheet 400, adopt strong adherence band 800 that strong adherence is carried out in the side of this vertical plane and display screen 101 again, optical component and display screen 101 is made to be connected into as a whole, the optical cement with higher clarity and solidification intensity that transparent Embedding Material 204 can adopt an embodiment the same.
These are only the specific embodiment of the invention, scope of the present invention can not be limited with this, the equalization change that those skilled in the art in the art do according to this creation, and the change that those skilled in that art know, all still should belong to the scope that the present invention is contained.
