In the such scheme, before the LED lamp, be provided with LGP.The light that LGP can make the LED lamp send is more concentrated, increases the effective transmission rate of light.
In the such scheme, a pixel on the corresponding combination cell edges of a said LED lamp.
In the such scheme, two or more pixels on the corresponding combination cell edges of a said LED lamp.Because the restriction of LED lamp size, when the resolution of displayed images of combination unit was big, the LED lamp can't satisfy the corresponding pixel of a LED lamp, and can adopt the pixel of the corresponding two or more display images of a LED lamp this moment.
In the such scheme, said LED lamp is three-in-one Surface Mount LED lamp.
Compared with prior art, the beneficial effect of technical scheme of the present invention is:
(1) the present invention is provided with the LED lamp through the edge joint position at the rear-projection combination, and the light that the LED lamp is sent passes piece and shows, and efficiently solves the problem of rear-projection combination piece black surround, makes the whole display effect of combination improve greatly, and display effect is remarkable.
(3) the present invention is because the LED lamp is depressed in the combination cell surface; Each LED lamp emits beam through arriving after the propagation of a segment distance on the rear-projection combination display plane; Not only the piece of rear-projection combination has been eliminated; Gap between initiate each LED lamp also has been eliminated simultaneously, the real purpose that realizes eliminating piece.
(3) LED lamp display control unit of the present invention reads the pixel at combination cell edges place, and through the demonstration of control LED lamp the edge's pixel that reads is shown, and makes image show that continuity is good, and the phenomenon of disconnection suddenly can not appear in image.
(4) the present invention is installed in edge joint position together with LED lamp display control unit and LED lamp, and is simple and compact for structure, easy for installation.
