Abstract:
The present invention provides a compound capable of forming an irregular wrinkled structure, a composition containing the compound, a film having the irregular wrinkled structure, a method of forming the film, and an organic light emitting diode comprising the film. The film can be formed with the irregular wrinkled structure by simply coating the compound of the present invention, and curing using UV rays or heat. By applying the formed film to the organic light emitting diode, light emitted from the organic light emitting diode is scattered on the surface of irregular wrinkles and is extracted to the outside after controlling the optical wave or total reflection. A random structure located on the outside of the diode functions as a light extraction unit for improving the light efficiency of the organic light emitting diode.

PURPOSE: A method for fabricating an organic light emitting diode is provided to simplify a fabrication process, by not including a vacuum process in an optical extraction mask forming process. CONSTITUTION: A substrate(100) is prepared. A rugged part(101) is formed on the substrate and is arranged at random. A planarization layer(102) planarizing the rugged part is formed on the rugged part. A first electrode is formed on the planarization layer. An organic light emission layer(104) is formed on the first electrode. A second electrode(105) is formed on the organic light emitting layer.
Abstract:
PURPOSE: A display device is provided to improve readability and color reproducibility and to save power consumption using a light emitting part for self emission and a pixel part for reflective emission. CONSTITUTION: A light emitting part(230) emits first wavelength light. The light emitting part includes a first electrode(231), an organic light emitting layer(233), and a second electrode(235). A pixel part(270) emits second wavelength light using reflected light. A capping layer(250) is laminated between the light emitting part and the pixel part. An optical sensor(260) measures the intensity of outside light. A control unit(280) operates the light emitting part and the pixel part according to the intensity of the light measured by the optical sensor.

PURPOSE: A light emitting device and a manufacturing method thereof are provided to improve external light efficiency by selectively arranging an optical path structure on only the second region with an auxiliary electrode. CONSTITUTION: A transparent substrate includes a first region and a second region. A first transparent electrode(102) is arranged on one side of the transparent substrate. A second transparent electrode(110) is separated from the first transparent electrode to face each other. An organic light emitting layer(108) is arranged between the first transparent electrode and the second transparent electrode. An auxiliary electrode(106) selectively masks the second region.
