The size of described LCDs is more than or equal to 82 cun.
The utility model is by being provided with at least one splicing circuit unit, by display chip in the splicing circuit unit with input picture synthetic after encoded again device outputting standard vision signal.Utilize the very large data bandwidth of having of display chip, do not need image is compressed, no longer have the problem of display resolution bottleneck compared to existing technology, display resolution and display effect obviously improve.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 be the utility model embodiment one liquid crystal display cut apart show two images cut apart the display splicing circuit;
Fig. 2 be the utility model embodiment two liquid crystal displays cut apart show four images cut apart the display splicing circuit.
Embodiment
The utility model liquid crystal display cut apart the display splicing circuit and display system is utilized the existing technology of professional display chip, realize that high definition of image cuts apart demonstration, the resolution that makes full use of the oversize liquid crystal display realizes better image tiled display effect.
The display splicing circuit of cutting apart of the utility model liquid crystal display comprises at least one splicing circuit unit; Described splicing circuit unit comprises at least one display chip and at least one scrambler that with described display chip output terminal be connected corresponding one by one with described display chip with, and described display chip has one input picture is incorporated in the picture-in-picture function module that shows in the image; Described display chip is merged into input picture one composograph and exports described scrambler to, and described scrambler converts the composograph of display chip output to video standard signal output.
Embodiment one
See also Fig. 1.Fig. 1 disclosed a kind of utilize Large-size LCD Screen to cut apart to show two images cut apart the display splicing circuit.The display splicing circuit of cutting apart of liquid crystal display only is provided with a splicing circuit unit in this specific embodiment.Wherein, this is cut apart the display splicing circuit and comprises that one receives the display chip and the scrambler that is connected with display chip of input picture, and scrambler is connected with large-sized liquid crystal display.Image 1 and image 2 are imported display chip respectively, and this display chip has a picture-in-picture function module.Because the picture-in-picture function module can realize showing simultaneously the effect of two pictures, therefore, the picture-in-picture function module in the display chip is incorporated in demonstration back output in the image with image 1 and image 2.Display chip output is the 4:4:4 digital interface of TTL standard, thereby need utilize scrambler again, and this 4:4:4 digital interface is become the video standard interface of DVI or VGA, delivers to Large-size LCD Screen and shows.
Embodiment two
See also Fig. 2, Fig. 2 disclosed a kind of utilize Large-size LCD Screen to cut apart to show four images cut apart the display splicing circuit.The display splicing circuit of cutting apart of liquid crystal display is provided with 3 splicing circuit units in this specific embodiment, and wherein, two parallel its output terminals that are provided with of splicing circuit unit all are connected with the input end that last splices the display chip of circuit unit.
This is cut apart the display splicing circuit and comprises display chip 1 and display chip 2, and display chip 1 and 2 is connected the back respectively by the parallel input end that is connected to display chip 3 of scrambler with a scrambler, output image was to large-sized liquid crystal display after the output terminal of display chip 3 connected a scrambler.Wherein, image 1 and 2 is imported display chip 1 respectively, is merged into a composograph through the picture-in-picture function module of display chip 1 and outputs to coder transitions and become video standard signal to export display chip 3 to import as one road image.In like manner, image 3 and 4 is imported display chip 2 respectively, is merged into a composograph through the picture-in-picture function module of display chip 2 and outputs to coder transitions and become video standard signal to export display chip 3 to as another road image input.The two-way image synthesizes through display chip 3 and becomes video standard signal to export LCDs to by coder transitions and shows.Thereby on LCDs, show image 1, image 2, image 3 and the image of cutting apart 4, thereby realized the demonstration of 4 road signals on same screen.Described video standard signal can export LCDs to by DVI or VGA interface.
This specific embodiment is by adopting three chip of LCD, wherein two respectively as two picture compositors, the 3rd synthesizes two pictures to the one or two input again, because the chip of LCD of specialty has very large data bandwidth, so through the signal of handling output is not to be compressed, be equivalent to direct output, resolution easily arrives 1920X1080.
In embodiment one and embodiment two, described LCDs all adopts 82 cun LCDs.Because 82 cun LCDs itself are exactly an independently monitor, resolution is 1920 * 1080, the competent fully splicing as 4 40 cun is used, by adopting professional chip of LCD input signal is integrated, realize cutting apart in single screen, the edge that has not had machinery to cut apart is really realized seamless spliced.Certainly, also adopt, and the special kind that limits LCDs of invention, but be preferably greater than or equal 82 cun LCDs greater than 82 cun or less than 82 cun LCDs.
Certainly, the cutting apart the display splicing circuit and can also be provided with more splicing circuit unit of liquid crystal display, as be provided with 7 the splicing circuit units, with the parallel input end that inserts the 7th display chip of 3 chips shown in the embodiment two, on LCDs, show 6 images cutting apart etc. through exporting LCDs behind the screen coding to again.
Because tradition is cut apart splicer and is generally matrix, and the software dispenser is also arranged, its common ground all is to compress processing to picture signal, makes it narrow down to 1/4th, and pixel just has and loses like this, and sharpness just descends, and is disadvantageous for monitoring.And by adopting the utility model because professional chip of LCD has very large data bandwidth, and the resolution of output signal can easily meet and exceed the resolution of 1920x1080, although so input signal has been done the picture-in-picture processing, but because final display terminal, the resolution of oversize liquid crystal display also is 1920x1080, so do not have the bottleneck of traditional dispenser in the whole transmission path, thereby realized that show and splicing cutting apart of high definition.
