Transparent LED display

摘要

Described herein is a transparent device for display of information superimposed on a background, said device comprising a plurality of LED sources (2), addressable individually or in groups through a series of conductive paths (10, 20) deposited on a transparent underlayer (1) and connected to a control electronics, in which: i) said LED sources are integrated in the form of dice, i.e., of elements obtained by dividing up a semiconductor wafer and without package; and ii) at least one of said conductive paths is with interrupted stretches and replaced by stretches (21) of metal wire, bonded to said paths through a wire-bonding operation.
