Abstract
The invention belongs to the technical field of televisions, and relates to a large spliced screen which is formed by splicing a plurality of liquid crystal screens with the same specification. The large spliced screen is characterized in that a transparent protective plate is fixed in the front of each liquid crystal screen, the size of each transparent protective plate is equal to that of the largest edge of each liquid crystal screen, a curved surface groove is arranged at the edge of one side of each transparent protective plate close to the corresponding liquid crystal screen, so that the edge of each transparent protective plate is in the shape of a half inwards concave lens, and two transparent protective plates fixed in the fronts of two mutually spliced liquid crystal screens form the shape of the concave lens at the mutually spliced edge by the aid of the curved surface grooves. Besides, the invention provides a method for decreasing image gaps by the aid of the large spliced screen. The large spliced screen has the advantages that the large spliced screen is simple in structure and low in cost, and splicing gaps can be remarkably reduced in terms of visual effect.
Description
Technical field
The invention belongs to TV technology, relate to a kind of liquid crystal-spliced giant-screen.
Background technology
Giant-screen in the market mainly contains liquid crystal-spliced formula, DLP is spliced and LED giant-screen, wherein LED giant-screen is only applicable to low resolution requirement, if make high-resolution LED giant-screen, cost is very high, 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, the new splicing rising in recent years, LCD liquid crystal display splicing wall has the advantages such as low-power consumption, lightweight, the life-span is grown (generally can normally work 50,000 hours), radiationless, picture brightness is even, but it is seamless spliced that its maximum shortcoming can not be accomplished exactly, concerning display frame requires very meticulous industry user, a little a little one is sorry.Because liquid crystal display just has a frame when dispatching from the factory, the liquid crystal-spliced frame (seam) that just there will be has 6-10mm as the frame of the liquid crystal displays of single 21 cun, and the seam that two liquid crystal displays connect just has 12-20mm.In order to reduce liquid crystal-spliced gap, there are in the industry at present several ways, a kind of is narrow slot splicing, another kind is microseam split, and microseam split is that the shell of the liquid crystal display buying is dismantled by manufacturer, will between glass and glass, splice, 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, and DID liquid crystal display aims at splicing and designs, and that when dispatching from the factory, just its frame is done is very little.
Summary of the invention
The above-mentioned deficiency that the object of the invention is to overcome prior art, provides a kind of simple structure, with low cost, from visual effect, can significantly dwindle the liquid crystal-spliced giant-screen that splices gap.The present invention adopts following technical scheme.
A kind of splicing large screen, LCD screen by polylith same size is spliced, it is characterized in that, before every LCD screen, fix a transparent protection plate, the maximal margins of transparent protection plate and LCD screen etc. are large, at every transparent protection plate, near the edge of a side of LCD screen, offer curved surface groove, make the edge of transparent protection plate be the shape of the lens that concave for half; Be fixed on two transparent protection plates before two LCD screen of mutual splicing, in the edge of splicing mutually, due to the existence of curved surface groove, form the shape of concavees lens.
The present invention provides a kind of method of utilizing the minimizing image slot that described splicing large screen realizes simultaneously: split screen device when processing visual signal display area according to the maximum outside dimension computed image of every LCD screen, the compression of images that the image that then every LCD screen should be shown at seam crossing and liquid crystal display district should show near the fringe region of seam crossing shows in the fringe region in liquid crystal display district, thus make edge image through split screen device process be twisted after again through the distortion of fender edge concavees lens and be reduced;
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 gap; utilization is installed at the transparent protection plate that fringe region has concavees lens effect before LCD screen; the method that coordinates again specific split screen process software; can reach the technique effect that can significantly dwindle splicing gap from visual effect; there is simple structure, be easy to realize and cheap advantage.
Accompanying drawing explanation
The splicing construction schematic diagram of Fig. 1 liquid crystal-spliced giant-screen of the present invention.
Accompanying drawing explanation: the lens cambered surface that in figure, 1 transparent protection plate, 2 transparency protected portions are cut into inner face edge, 3 LCD screen viewing areas, 4 liquid crystal displays are without showing edge
Embodiment
Below in conjunction with drawings and Examples, the present invention will be described.
Referring to Fig. 1; the joining method of the present embodiment is: before each LCD screen, install a transparent protection plate additional; the maximal margins of transparent protection plate and LCD screen etc. are large; at each transparent protection plate, near the edge of a side of LCD screen, cut, carve or polish curved surface groove; make the edge of transparent protection plate form the shape of the lens concave for half, four angles of transparent protection plate are fixed with whole link of metallic bond fitting and LCD screen.When carrying out LCD screen splicing, be fixed on the also splicing mutually of transparent protection plate of two LCD screen outsides, thereby make the place that two transparent protection plates splice mutually two LCD screen form lens.Concavees lens just equal a type minifier from visually dwindling splicing gap, simultaneously split screen device when processing visual signal display area according to the maximum outside dimension computed image of liquid crystal display, the image of the image that then the monolateral seam of liquid crystal should be shown and liquid crystal display area edge (2mm～3mm) (being altogether no more than the image that the scope of 6mm should show) is compressed in edge of display area, the image of edge of display area is owing to facing the edge of fender, because spliced Liang Ge fender edge is equivalent to concavees lens, when the splicing gap image with corresponding position, concavees lens center is dwindled by concavees lens, image in concavees lens marginarium is but 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, make whole visual gap minimum, thereby distortion when edge image is processed through split screen device is reduced after the distortion of fender edge lens again.
During concrete enforcement, adopt transparent acrylic as 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, split screen device has image to show the screen primary image information of first calculating according to all areas of liquid crystal board image, then the Information Compression 6mm region at the edge of screen being 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 be twisted distortion behind concavees lens edge after, picture without the liquid crystal edge of image is reduced.
