Abstract: Provided are a hybrid white organic light emitting diode (OLED) and a method of fabricating the same. A HOMO level difference between a fluorescent emission layer and an electron transport layer in an organic emission layer (OLED) becomes higher than that between the other layers or a LUMO level difference between a fluorescent emission layer and a hole transport layer is higher than that between the other layers, so that a recombination region is restricted to a part of an emission layer to obtain high-efficiency fluorescent light emission. In addition, triplet excitons that are not used in a fluorescent emission layer are transferred to an auxiliary emission layer formed to be spaced apart from a recombination region by a predetermined distance to emit light in a different color from the fluorescent emission layer, so that both singlet and triplet exicitons formed in the OLED are used to obtain high-efficiency white light emission.

Abstract: PURPOSE: A method for sensing degradation in a lighting device and a lighting device using the same are provided to uniformly maintain the brightness of light generated in a light emitting part by controlling a driving signal applied to a light emitting diode by using light detected in a sensor unit. CONSTITUTION: An initial drive signal is generated(S10). Light is generated from an organic light emitting diode by using the initial drive signal(S20). A part of the generated light is received and sensing information is generated(S30). A compensation signal is generated by comparing the sensing information with reference information corresponding to the initial drive signal(S40). The compensated drive signal is generated by using the compensation signal(S50).
