    Abstract: PURPOSE: A high efficiency white organic light emitting material and an electroluminescence device are provided to achieve improved luminous efficiency and allow for ease of manufacture of white light emitting material. CONSTITUTION: A high efficiency white organic light emitting material comprises a substrate(1) having a half-transparent electrode(2); a light emitting layer(4) formed on the half-transparent electrode; and a metal electrode(6) formed on the light emitting layer. The light emitting layer is made of organic light emitting materials of three or more components. The material having the highest band gap is used as a host, and the other materials are used as a dopant which is doped at 0.1 weight% or lower of the host material.

    Abstract: PURPOSE: A device and a method for self-fault detection of a microphone and an audio-based device are provided to improve the reliability of a system through a self-control operation of an audio signal received to a defective microphone. CONSTITUTION: A self-failure detector(200) generates a reference wave signal of a failure diagnosis, and detects the defect of the microphone by comparing a pre-stored reference signal with an audio signal received to the microphone. A control unit(300) controls the processing of an audio signal inputted from the defective microphone according to a defect allowance level reference value of a system for the defective microphone.
