Description
Technical field
The present invention relates to a kind of video image display, particularly to a kind of seamless spliced device of liquid crystal display screen optics。
Background technology
Existing seamless spliced technology mainly adds light refraction or reflection unit before screen, is amplified by the image of edge or reflection is to hide piece。Shortcoming is that viewing angle is very sensitive, and mainly during tilted direction viewing, pattern distortion is serious, the situation of image offset even occurs。Owing to liquid crystal exists edge sealing, the lifting that can not pass through manufacturing process in theory is eliminated, and the driving connecting line of liquid crystal is in screen example limit and will also result in certain seal ring thickness simultaneously。Therefore, when multi-screen splices, inevitably there will be splicing seams gap (namely there is interval between image and image)。The method that someone adopts light refraction at present, reflects the image of screen edge and covers piece, belong to passive compensation。
The present invention adopts active illuminating compensation way to realize the elimination of LCD screen piece。Use LED pixel array as active illuminating light source, according to liquid crystal pixel size design LED pixel array period, form the additional pixels for covering piece。On current LCD screen, liquid crystal pixel typical cycle is of a size of 0.63mm × 0.63mm, and the LED pixel cycle should be the integral multiple of liquid crystal pixel periodic dimensions。
Summary of the invention
The present invention relates to a kind of seamless spliced device of liquid crystal display screen optics, by additional pixels display device, active illuminating compensates the image of the splicing seams caused by LCD screen frame, thus reaching the purpose of seamless spliced LCD screen。
A kind of seamless spliced device of liquid crystal display screen optics, is made up of metal end liner, LED pixel array, flexible circuit board, scattering cover and protection housing；Described metal end liner is directly closely affixed on LCD screen frame, with L-type bending, its L-type bending is stamped with aperture, fixing for scattering cover；LED pixel array is welded in flexible circuit board, the L-shaped metal end liner that is closely affixed on of flexible circuit board, and the flexible circuit board other end connects LED drive circuit plate；Scattering cover is formed by translucent PC material injection, is covered on LED pixel array, is fixed by the aperture at edge with metal end liner simultaneously；Outermost protection housing is used for fixing and protecting flexible circuit board；
LED pixel array period in described flexible circuit board determines according to liquid crystal display screen liquid crystal pixel size。
Described metal end liner is the corrosion resistant plate of 0.25mm。
The columns of described LED pixel array is according to liquid crystal display screen frame size and LED pixel array period size design；
Setting border width as D, LED pixel array period is d, then columns n=the D/d of LED pixel array；
When n=N ± 0.2 (N is nonnegative integer), then take n=N；
As N+0.2 < n < N+0.8, then taking n=N+1, the method simultaneously passing through to thicken metal end liner makes border width increase to (N+1) d。
Described flexible circuit board be the connecting line between LED pixel array with driver circuit plate and LED pixel array weld carrier。
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 side is inserted in the through hole of metal end liner L bending avris, then dissipates colour correction mask latch shape structure to melted in another side heating, is just pressed together on metal bottom lining by firm for flexible circuit board after cooling。
Metal end liner good for pressing 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 screen is fixed。Flexible circuit board is linked in liquid crystal display screen drive circuit board behind。
The structure of described scattering cover is the combination of periodically plinth and spherical dome；Wherein, plinth outside dimension is LED pixel array period size, inside has square groove, and size is identical with LED pixel array sizes, for covering on LED pixel array；Spherical dome energy scattering LED institute is luminous, and square periodic structure makes again institute's luminous color between adjacent LED units to interact simultaneously。
The present invention adopts LED pixel array to carry out Active Compensation。LED pixel array is directly fixed on above the frame of LCD screen by flexible circuit board, on LED pixel array, installs scattering cover additional simultaneously, make LED pixel array light-emitting uniform in all directions。Owing to the lighting angle of LED own is uniform, therefore different viewing angle does not affect image, and scattering cover is by light scattering to fill up the interval between LED simultaneously, ultimately forms each to uniform and continuous print pixel array。
The present invention uses the compensation of LED active illuminating that piece is covered, and scattering cover eliminates the gap between LED luminescence unit simultaneously。
The beneficial effects of the present invention is: the invention solves the pattern distortion problem produced due to the change of viewing angle in passive compensation, the problems such as serious anamorphose, dislocation will not be caused on image shows because of the change of viewing angle。
