Patent ID: 8692242

Claim:
A candlelight-like light organic light-emitting device, comprising: a first conductive layer; a hole injection layer, being formed on the first conductive layer; a hole transport layer, being formed on the hole injection layer; a first host light-emitting layer, being formed on the hole transport layer; a second host light-emitting layer, being formed on the first host light-emitting layer; an electron transport layer, being formed on the second host light-emitting layer; an electron injection layer, being formed on the electron transport layer; and a second conductive layer, being formed on the electron injection layer; wherein a plurality of candlelight complementary color dyes are doped in the first host light-emitting layer and the second host light-emitting layer for making the first host light-emitting layer and the second host light-emitting layer respectively emit a first light and a second light, such that the first light and the second light are mixed to a candlelight-like light with high color rendering index and low color temperature.
