Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
In the prior art that overcomes Fig. 1 .a and Fig. 1 .b, exist and watch dead band 300, can only realize the defective of seamless spliced effect in the front, the present invention adopts the mode that increases optical sheet will watch sight line to reconfigure, and makes and can both realize seamless spliced effect on all angles.
Be depicted as the first embodiment of the present invention as Fig. 2 .a and 2.b, the center section of display screen 101 is viewing area 103 in the present embodiment, and the marginal portion is frame 102.Above frame 102, be provided with the compensation display device, be used for compensating because the display part that frame 102 blocks.In the present embodiment, the compensation display device is the LED device, specifically comprises for the pcb board 201 of control LED202 with for the protection of the protective cover of LED202.It will be appreciated that for the compensation display device of other types, for example OLED or small-sized LCD panel are applicable among the present invention too.Concrete, the compensation display device in the present embodiment comprises the pcb board 201 that is sticked on frame, the LED202 that is electrically connected with pcb board, covers the outer protective cover 203 of LED202.
Be provided with optical sheet 400 above viewing area 103, 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 becomes reflecting surface 401 for facing directly and in advance this end face being carried out optical coating with it.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 paste 402 zone line and optical sheet 400 applyings greater than the hyaline membrane of optical component, the zone line of hyaline membrane subsides 402 is fitted with the exiting surface of optical sheet 400 earlier or is bonding, and fringe region is adhesively fixed through after bending and the side of display screen 101.The viewing effect at its angle of inclination originally drops on the sight line of watching the dead band face 401 that is reflected and adjusts shown in Fig. 2 .b, drops on the viewing area 101, also can obtain seamless spliced effect like this on the pitch angle.
Be illustrated in figure 3 as the second embodiment of the present invention; in the present embodiment; optical sheet 400 has adopted different structures: the marginal portion of optical sheet 400 processes a width and the L shaped breach that compensates display device width coupling; to compensate display device and place among L shaped breach and the formed space of display screen frame, cancel the protective cover 203 among first embodiment.Present embodiment will not be owing to will compensate display device and optical sheet 400 carries out bonding, facing directly of the L shaped breach of optical sheet 400 directly forms fully reflecting surface in air dielectric, the reflecting surface that forms through optical coating among its optical effect and first embodiment is identical, therefore, present embodiment can be realized the identical optical effect with first embodiment, the no frame that is implemented in any viewing angle shows, and fabrication and installation technology is simpler than first embodiment.
Be depicted as the third embodiment of the present invention as Fig. 4 .a and Fig. 4 .b, present embodiment is based on the improvement of second embodiment, because the compensation display device adopts the higher LED of brightness, and the display screen 101 lower liquid crystal board of brightness normally, both have tangible difference in brightness, only adjust the brightness regulation that is difficult to both by the electronics mode and arrive consistent.For with this obviously difference eliminate, install an optical attenuation sheet 500 additional at the exiting surface of LED, the concrete structure of optical attenuation sheet 500 is shown in Fig. 4 .b.The surface of light decay sheet is arranged alternately photic zone 502 and the light tight district 501 that is parallel to each other, this array pattern can adopt inkjet printing to make to transparent sheet, again the optical attenuation sheet of making 500 is pasted on the plane of L shaped breach of optical sheet of the luminous place of LED correspondence, also can directly adopt suitable technology stamp designed array pattern on this plane and constitute the optical attenuation face.
And consider lambert's characteristics of luminescence of LED and non-lambert's characteristics of luminescence of LCD panel, and watch in different angles, can't finely satisfy the purpose of all angles viewing effect unanimity by the mode of simple decay LED brightness.For this reason, in the fourth embodiment of the present invention, install a micro-optic sheet 600 additional at the exiting surface of LED, 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 its surperficial parameter, obtain the consistent effect of brightness on all angles.In the time of concrete enforcement, can be by on transparent smooth optical sheet, method with chemical agent or Physical Processing, make the surface of transparent optical sheet become coarse, make transparent smooth optical sheet become the micro-optic sheet 600 that meets our needs, make the attenuation degree unanimity of all angles; Also can directly make the micro-optic sheet 600 with microlens array, microtrabeculae lens array or microprism array by modes such as direct moulded section or injection mo(u)ldings, concrete array parameter can be adjusted flexibly according to the size of actual product, the brightness of compensation display device etc.
Be illustrated in figure 6 as the fifth embodiment of the present invention, in the present embodiment, the breach of optical sheet 400 is forged into C shape, and the vertical plane of C v notch v is plated to reflecting surface 401, will compensate display device again and place in this C v notch v and fix near place, plane, top and with transparent Embedding Material 204 embeddings.Fix by embedding; the compensation display device will form one with optical sheet 400; do like this and be conducive to the producer and produce assembling, simultaneously transparent Embedding Material adopts the optical cement with higher clarity and solidification intensity, makes the compensation display device be effectively protected.On the lower surface of compensation display device and C v notch v, leave the gap, this gap is applicable to inserts L shaped dihedral brace 700, makes that the relative position between display screen 101 and the optical sheet 400 is fixed.L shaped dihedral brace 700 has two planes that become 90 °, and one of them plane is inserted into the gap on the lower surface that compensates display device and C v notch v, and further bonds together; Another plane then with the side fixed bonding of display screen 101.By L shaped dihedral brace 700, can improve intensity and the steadiness of whole display device.
Be the sixth embodiment of the present invention as Fig. 7.Because the optical sheet 400 in a last embodiment is the C v notch v, such breach is fit to install additional L shaped dihedral brace.And when the breach of optical sheet 400 when being L shaped, then change over structure as shown in Figure 7.The vertical plane of L shaped breach is plated to reflecting surface 401, to compensate display device again places in this L shaped breach and fixes near place, plane, top and with transparent Embedding Material 204 embeddings, make compensation display device and optical sheet 400 be connected into optical component, must guarantee when carrying out embedding with transparent Embedding Material 204 at vertical plane of the additional formation of the outer rim of optical sheet 400, it is bonding to adopt powerful splicing tape 800 that brute force is carried out in the side of this vertical plane and display screen 101 again, it is as a whole that optical component and display screen 101 are connected into, and transparent Embedding Material 204 can adopt the same optical cement with higher clarity and solidification intensity of an embodiment.
It below only is the specific embodiment of the invention, can not limit scope of the present invention with this, the equalization that those skilled in the art in the art do according to this creation changes, and the change known of those skilled in that art, all should still belong to the scope that the present invention is contained.
