LED e.g. organic LED, chip, has emitter layer that is arranged between another emitter layer and third emitter layer, and radiation-producing emission zones of emitter layers arranged at distance from each other and from mirror layer

摘要

The chip has three emitter layers (101-103) with radiation-producing emission zones (111-113), in which respective light waves are produced. The emitter layer (101) is arranged between a mirror layer (40) and the emitter layer (102), and the emitter layer (102) is arranged between the layers (101, 103). The emission zones of the emitter layers are provided at a distance from each other and from the mirror layer. A spacer layer is arranged between the mirror layer and the emitter layer (101), and another spacer layer is arranged between the layers (101, 102).
