Abstract (en)
[origin: WO2005101531A2] The invention relates to a thin-film light-emitting diode chip in which the distance between a reflective layer (4) and a light-generating active zone (3) is such that radiation from the active zone (3) interferes with light reflected by the reflective layer (4). The interference affects the internal quantum efficiency of the active zone (3), and consequently the active zone has an emission characteristic with at least one preferred direction.
