ABSTRACT:
A double-faced light emitting diode display includes a pair of parallel shield panels (20, 20′), and a light emitting module (30) located between the shield panels. Each shield panel includes a video contrast enhancement assembly. The light emitting module includes an opaque insulative substrate (31) with a pair of pixel matrixes symmetrically formed on opposite surfaces (310, 310′) thereof and a circuit driving system formed at at least one of the surfaces. Each pixel matrix includes a plurality of pixel units (320, 320′). Symmetrically opposite pairs of pixel units are electrically interconnected so that the shield panels can simultaneously display same images. The double-faced light emitting diode display has a simple structure, a small size, low cost and full color display capability, and can be advantageously applied in traffic signal boards, large-scale display boards, surround cinemas and so on.
