Description
Technical field
The present invention relates to a kind of video image display, particularly the seamless spliced device of a kind of liquid crystal display optics.
Background technology
Existing seamless spliced technology is mainly before screen, to add light refraction or reflection unit, the image of edge is amplified or reflect to hide piece.Shortcoming is very responsive to viewing angle, be mainly tilted direction while watching pattern distortion serious, even there is the situation of image offset.Because liquid crystal exists edge sealing, can not be eliminated by the lifting of manufacturing process in theory, the driving connecting line of liquid crystal also can cause certain seal ring thickness in screen side simultaneously.Therefore when multi-screen splices, inevitably there will be splicing gap (being to have interval between image and image).Someone adopts the method for light refraction at present, and the image refraction of screen edge is covered to piece, belongs to passive compensation.
The present invention adopts active illuminating compensation way to realize the elimination of LCD screen piece.Use LED pel array as active illuminating light source, according to the liquid crystal pixel size design LED pel array cycle, be formed for covering the additional pixels of piece.In LCD screen, liquid crystal pixel typical cycle is of a size of 0.63mm * 0.63mm at present, and LED pixel period should be the integral multiple of liquid crystal pixel cycle size.
Summary of the invention
The present invention relates to the seamless spliced device of a kind of liquid crystal display optics, by additional pixels display device, active illuminating compensates the image at the splicing seams place being caused by LCD screen frame, thereby reaches the object of seamless spliced LCD screen.
The seamless spliced device of liquid crystal display optics, is comprised of metal end liner, LED pel array, flexible circuit board, scattering cover and protection housing; Described metal end liner is directly closely affixed on LCD screen frame, and with L-type bending, its L-type bending upper punch is pressed with aperture, for fixing of scattering cover; LED pel array is welded in flexible circuit board, and flexible circuit board is L-type and is closely affixed on metal end liner, and the flexible circuit board other end connects LED drive circuit plate; Scattering cover is formed by the injection moulding of translucent PC material, is covered on LED pel array, fixes with metal end liner by the aperture at edge simultaneously; Outermost protection housing is for fixing and protection flexible circuit board;
Described liquid crystal display liquid crystal pixel size determined according to the LED pel array cycle in flexible circuit board.
The corrosion resistant plate that described metal end liner is 0.25mm.
The columns of described LED pel array is according to liquid crystal display frame size and LED pel array cycle size design;
Setting border width is D, and the LED pel array cycle is d, columns n=the D/d of LED pel array;
When n=N ± 0.2 (N is nonnegative integer), get n=N;
As N+0.2 < n < N+0.8, get n=N+1, by thickening the method for metal end liner, make border width be increased to (N+1) d simultaneously.
Described flexible circuit board is connecting line between LED pel array and driver circuit plate and the welding carrier of LED pel array.
Flexible circuit board is placed in the L-type bending of metal end liner, adds a cover scattering cover simultaneously.The latch shape structure of scattering cover one side is inserted in the through hole of metal end liner L bending avris, then in the loose colour correction mask latch shape structure of another side heating to melting, just flexible circuit board is firmly pressed together on to metal bottom after cooling and is lining with.
The metal end liner that pressing is good is placed in LCD screen edge, at outermost covering protection frame, by sunk screw, the structures such as bearer bar and metal end liner and liquid crystal display is fixed.Flexible circuit board is linked in liquid crystal display drive circuit board behind.
The structure of described scattering cover is the combination of periodicity plinth and spherical dome; Wherein, plinth outside dimension is LED pel array cycle size, inside has square groove, and size is identical with LED pixel array size, for covering on LED pel array; Spherical dome energy scattering LED institute is luminous, and square periodic structure makes again institute's luminous color between adjacent LED unit can not interact simultaneously.
The present invention adopts LED pel array to carry out Active Compensation.LED pel array is directly fixed on to the frame top of LCD screen by flexible circuit board, on LED pel array, installs scattering cover additional, make LED pel array luminous even in all directions simultaneously.Because the lighting angle of LED own is even, therefore different viewing angle does not affect image, the cover of scattering is simultaneously by light scattering to fill up the interval between LED lamp, and final formation is respectively to even and continuous pixel array.
The present invention uses the compensation of LED active illuminating to cover piece, and the cover of scattering is simultaneously eliminated the gap between LED luminescence unit.
Beneficial effect of the present invention is: the invention solves in passive compensation the pattern distortion problem that the variation due to viewing angle produces, on image shows, can not cause because of the variation of viewing angle the problems such as serious anamorphose, dislocation.
