Patent ID: 8294145

Claim:
An organic light emitting diode device, comprising: a substrate; a first electrode layer formed on the substrate, the first electrode layer comprising a first area and a second area adjacent to the first area and providing a plurality of first carriers and a plurality of second carriers; a first insulating layer formed on the first area; at least one controlling electrode layer formed on the first insulating layer; a second insulating layer formed on the controlling electrode layer; at least one light emitting layer formed on the second area for emitting light; a third insulating layer formed between the controlling electrode layer and the light emitting layer; and a second electrode layer formed on the light emitting layer and providing the other one of the first carriers and the second carriers; wherein the controlling electrode layer controls a recombination region of the first carriers and the second carriers in the light emitting layer for controlling the light emitting layer to emit light.
