Transparent LED display
First Claim
1. A transparent-display device for motor vehicles, to be used for the presentation of information to the driver and/or to the passenger, said device comprising a plurality of LED sources, addressable individually or in groups through a series of conductive paths, deposited on a transparent underlayer and connected to a control electronics, said device being characterized in that:
- i) said LED sources are integrated in the form of dice, said dice comprising elements obtained by dividing up a semiconductor wafer and without package;
ii) said dice are integrated on and electrically connected to said underlayer using technologies of the chip-on-board (COB) type; and
iii) said transparent underlayer I is pre-arranged for being at least in part superimposed on the windscreen of the vehicle, in such a way that at least part of the information presented to the user is superimposed on the background, said background being visible to the user through said windscreen.
