Abstract

A flexible lighting panel comprising a light-emitting unit with electrical contact pads on a flexible substrate; a flat flexible printed circuit board with a bendable extension tab, wherein the circuit board is located on the opposite side of the light-emitting unit from the substrate; the area of the circuit board, not including the extension tab, is the same or greater than and overlaps the emissive area of the light-emitting unit; and the circuit board has at least two flat electrical connectors in electrical contact with the contact pads of the light-emitting unit; the flat electrical connectors extending along the extension tab of the circuit board for connection to a power source. The light emitting unit can be an OLED. The extension tab can be bent so that the flat electrical connections become accessible in different orientations. The panel can be ultrathin.
