Description
Technical field
The utility model 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 mainly adds light refraction device before screen, by the Nonlinear magnify of edge to hide piece.Shortcoming is very responsive to viewing angle, and mainly during tilted direction viewing, pattern distortion is serious, even occurs the situation of image offset.Because liquid crystal exists edge sealing, can not be eliminated in theory by the lifting of manufacturing process, the driving connecting line of liquid crystal is in screen side and also can causes 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).Someone adopts the method for light refraction at present, the refraction of the image of screen edge is covered piece, belongs to passive compensation.
Utility model content
The utility model relates to the seamless spliced device of a kind of liquid crystal display optics, and by additional pixels display device, active illuminating compensates the image of the splicing seams caused by LCD screen frame, thus reaches the object of seamless spliced LCD screen.
The seamless spliced device of a kind of liquid crystal display optics, is made up 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, fixing for scattering cover; LED pel array is welded in flexible circuit board, and flexible circuit board is that L-type is closely affixed on metal end liner, 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 pel array, fixes with the aperture of metal end liner by edge simultaneously; Outermost protection housing is used for fixing and protection flexible circuit board.
Described metal end liner is the corrosion resistant plate of 0.25mm.
Described flexible circuit board be connecting line between LED pel array with driver circuit plate and LED pel array weld carrier.
The structure of described scattering cover is the combination of periodically plinth and spherical dome; Wherein, plinth outside dimension is LED pel array periodic dimensions, 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 units interact simultaneously.
The utility model adopts LED pel array to carry out Active Compensation.Above frame LED pel array being directly fixed on LCD screen by flexible circuit board, on LED pel array, install scattering cover additional simultaneously, make LED pel array luminous even in all directions.Because the lighting angle of LED own is even, therefore different viewing angle not effect diagram picture, the cover of scattering simultaneously by light scattering to fill up the interval between LED, final formed each to even and continuous print pixel array.
The utility model uses the compensation of LED active illuminating to cover piece, and the gap between LED luminescence unit eliminated by the cover of scattering simultaneously.
The beneficial effects of the utility model are: the utility model solves the problem of pattern distortion in passive compensation, and image display can not cause the problems such as serious anamorphose, dislocation because of the change of viewing angle.
