Abstract: |
The double-sided LED device includes two parallel shield plates, and one light emitting module between these two shield plates. Each of these two shield plates in the same structure has contrast strengthening unit including dark section, white reflecting section and through hole. The light emitting module includes one opaque insulating base plate, two pixel matrixes formed symmetrically on two opposite surfaces and exciting circuit system formed on at least one surface. The double-sided LED device includes also symmetrical pixel electrode connection circuit resulting in double-sided display of the same image. The double-sided LED device has the advantages of full utilization of display space, simple structure, low cost, etc. and may be used in traffic indication plate, large information display board, cineorama, etc. |
