In such scheme, before LED, be provided with light guide plate.The light that light guide plate can make LED send is more concentrated, increases the effective transmission rate of light.
In such scheme, a pixel in the corresponding combination cell edges of a described LED.
In such scheme, two or more pixels in the corresponding combination cell edges of a described LED.Due to the restriction of LED size, when the resolution of displayed images of combination unit is larger, LED cannot meet the corresponding pixel of a LED, now can adopt the pixel of the corresponding two or more display image of a LED.
In such scheme, described LED is three-in-one surface-mount LED.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
(1) the present invention is by arranging LED at the edge joint position of rear-projection combination, and the light that LED is sent shows through piece, efficiently solves the problem of rear-projection splicing seams of splicing wall black surround, and the overall display effect of combination is improved greatly, and display effect is remarkable.
(3) the present invention is depressed in combination cell surface due to LED, each LED emits beam and arrives on rear-projection combination display plane after the propagation of a segment distance, not only the piece of rear-projection combination has been eliminated, also be eliminated with the gap between stylish each LED added, the real object realizing elimination piece.
(3) LED display control unit of the present invention reads the pixel at combination cell edges place, and edge's pixel of reading is shown by controlling LED display, and make image show continuity good, image there will not be the phenomenon disconnected suddenly.
(4) LED display control unit is arranged on edge joint position by the present invention together with LED, simple and compact for structure, easy for installation.

Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.
As shown in Figure 1, be structural representation of the present invention; A kind of device eliminating rear-projection splicing seams of splicing wall, rear-projection combination 101 comprises some combination unit, piece 100 is formed between combination unit and combination unit, piece 100 place is provided with LED 102A, LED display control unit 102 and stationary installation 103, wherein, LED 102A is arranged on piece 100 place being depressed in combination cell surface, and namely LED 102A and combination unit 101 surface are not at grade; Stationary installation 103 is arranged on the frame 104 of combination unit, and LED 102A and LED display control unit 102 are fixed on piece 100 place by stationary installation 103, and LED 102A is connected with LED display control unit 102.
Stationary installation 103 is fixed head, sheet metal can be adopted to make, be provided with heat-sink unit, possess heat sinking function.
LED 102A adopts the LED of three-in-one surface-mount, and each LED 102A comprises RGB tri-primary colours.
As shown in Figure 2, LED display control unit 102 comprises main control unit 102B and point control module 102C, main control unit 102B is connected with a point control module 102C, and a point control module 102C is connected with LED 102A, controls lighting of R, G, B tri-primary colours of LED 102A respectively.Wherein, main control unit 102B reads edge's pixel of combination unit, and controls to divide a control module 102C to light corresponding LED 102A.As shown in Figure 3, main control unit 102B reads edge's pixel of a combination unit, resolution of displayed images as combination unit is 1024*768, main control unit 102B reads edge's pixel of combination unit, and controlling RGB tri-primary colours that point control module 102C lights each LED 102A, the piece of the light therethrough rear-projection combination of LED 102A shows.
The pixel of LED 102A display and the corresponding relation of combination cell edges place pixel can be one to one, a pair two, a pair third-class, because the size of LED 102A limits (minimum spacing between LED is about 2mm), therefore when the resolution of displayed images of combination unit is larger, LED 102A cannot meet the corresponding pixel of a LED 102A, the pixel of corresponding two the display images of a LED 102A can be adopted, when namely reading edge's pixel of combination unit by main control unit 102B, every two image pixels only choose one, control LED 102A and show a pixel.As shown in Figure 3, two edge pixels 302 in the present embodiment on a corresponding combination unit of LED 102A.
