Giant-screen in the market mainly contains liquid crystal-spliced formula, DLP is spliced and the LED giant-screen, wherein the LED giant-screen is only applicable to the low resolution requirement, then cost is very high if make high-resolution LED giant-screen, so high resolution large screen mainly adopts two kinds of liquid crystal-spliced mode, DLP connecting methods at present.
LCD splicing (liquid crystal-spliced) is after DLP splicing, PDP splicing, a new splicing that rose in recent years, the LCD liquid crystal display splicing wall has low-power consumption, lightweight, life-span long (generally can work 50,000 hours), radiationless, the advantage such as picture brightness is even, but it is seamless spliced that its maximum shortcoming can not be accomplished exactly, concerning display frame required very meticulous industry user, a little a bit one is sorry.Because liquid crystal display just has a frame when dispatching from the factory, liquid crystal-spliced frame (seam) will appear, as the frame of single 21 cun liquid crystal display, 6-10mm is arranged, the seam that two liquid crystal displays connect just has 12-20mm.In order to reduce liquid crystal-spliced slit, several ways are arranged in the industry at present, a kind of is narrow slot splicing, another kind is microseam split, and to be manufacturer dismantle the shell of the liquid crystal display that buys to microseam split, will splice between glass and the glass, but the risk of this way is larger, if it is bad that liquid crystal display is torn open, can damage the quality of whole liquid crystal display, at present domestic have only a few manufacturer to make in this way.In addition, after 2005, Samsung has been released splicing special liquid crystal screen---DID liquid crystal display, DID liquid crystal display aim at splicing and design, when dispatching from the factory just its frame do very little.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, a kind of simple structure, with low cost is provided, can significantly dwindle the liquid crystal-spliced giant-screen in splicing slit from visual effect.The present invention adopts following technical scheme.
A kind of splicing large screen, LCD screen by the polylith same size is spliced, it is characterized in that, fix a transparent protection plate in the front of every LCD screen, the maximal margins of transparent protection plate and LCD screen etc. are large, offer the curved surface groove at every transparent protection plate near the edge of a side of LCD screen, so that the edge of transparent protection plate is the shape of the lens that concave for half; Be fixed on two transparent protection plates of two LCD screen fronts of mutual splicing, in the edge of mutually splicing, since the existence of curved surface groove, the shape of concavees lens of formation.
The present invention provides a kind of method of utilizing the minimizing image slot that described splicing large screen realizes simultaneously: the split screen device when processing visual signal display area according to the maximum outside dimension computed image of every LCD screen, then every LCD screen is shown in the fringe region in liquid crystal display district near the compression of images that the fringe region of seam crossing should show in image that seam crossing should show and liquid crystal display district, thereby so that edge image is processed through the split screen device is reduced through the distortion of fender edge concavees lens after being twisted again;
The method of described minimizing image slot, the width of the fringe region in described liquid crystal display district can be 2mm～3mm.
The method in splicing large screen structure provided by the invention and downscaled images slit; utilization is installed at the transparent protection plate that fringe region has the concavees lens effect before LCD screen; the method that cooperates again specific split screen process software; can reach the technique effect that can significantly dwindle the splicing slit from visual effect; have simple structure, be easy to realize and cheap advantage.
Description of drawings
The splicing construction synoptic diagram of Fig. 1 liquid crystal-spliced giant-screen of the present invention.
Description of drawings: 1 transparent protection plate among the figure, 2 transparency protected lens cambered surfaces that are cut into to the inner face edge, 3 LCD screen viewing areas, 4 liquid crystal displays are without showing the edge
Embodiment
The present invention will be described below in conjunction with drawings and Examples.
Referring to Fig. 1; the joining method of present embodiment is: install a transparent protection plate before each LCD screen additional; the maximal margins of transparent protection plate and LCD screen etc. are large; cut, carve or polish the curved surface groove at each transparent protection plate near the edge of a side of LCD screen; so that the shape of the lens that the formation of the edge of transparent protection plate concaves for half is fixed four angles of transparent protection plate with metallic bond fitting and whole link of LCD screen.When carrying out the LCD screen splicing, be fixed on the also mutually splicing of transparent protection plate of two LCD screen outsides, thereby so that two transparent protection plates form lens in the place that two LCD screen are spliced mutually.Concavees lens just equal a type minifier from visually dwindling the splicing slit; simultaneously the split screen device when processing visual signal display area according to the maximum outside dimension computed image of liquid crystal display; (image of 2mm～3mm) (altogether being no more than the image that the scope of 6mm should show) is compressed in edge of display area for the image that then should show the monolateral seam of liquid crystal and liquid crystal display area edge; the image of edge of display area is owing to face the edge of fender; because spliced two fender edges are equivalent to concavees lens; when the splicing slit image with corresponding position, concavees lens center is dwindled by concavees lens; image in the concavees lens marginarium but is exaggerated; through the debugging to the bent picture of split screen data fit lens; the whole phenomenon effect that can reach splicing large screen is best; so that whole visual slit is minimum, thereby so that the distortion of edge image when processing through the split screen device be reduced after the distortion through fender edge lens again.
During implementation; adopt transparent acrylic as the fender material; four angles of fender are fixed together with 0.5mm sheet metal and liquid crystal display housing cornerite; acrylic fender thickness is 4mm; the concavees lens concave surface major axis 12mm that chamfering goes out; 6 millimeters of minor axises; adopt liquid crystal board monolateral without viewing area width 3mm; the split screen device has image to show the screen primary image information of at first calculating according to all areas of liquid crystal board image; then the Information Compression that the 6mm zone at the edge of screen is shown to the edge of display area output image information of 3mm to each liquid crystal display; liquid crystal display edge 3mm is shown as wider image with the image of compression after being twisted distortion behind the concavees lens edges, then reduced without the picture at the liquid crystal edge of image.
