FLEXIBLE LIGHT EMITTING SYSTEM

Abstract:

A flexible light emitting system is provided and includes a flexible printed circuit layer that has a substrate with a top in surface and a bottom surface and a plurality of traces of silver paste disposed on the top surface. A plurality of micro light emitting diodes are disposed on the top surface and soldered to the plurality of traces to provide light. An elastic interlayer film of ethylene vinyl acetate copolymer extends over the top surface of the flexible printed circuit layer for protection of the plurality of micro light emitting diodes and the plurality of traces. A diffuser layer extends over the elastic interlayer film opposite the flexible printed circuit layer to diffuse the light from the plurality of micro light emitting diodes. An optically transparent material layer extends between the elastic interlayer film and the diffuser layer to provide a uniform light appearance.
