Abstract: Methods for fabricating an optical waveguide and a display device and a photomask used therein is provided. Firstly, a photomask is provided, wherein the photomask has light blocking structures regularly distributed. A first light curing resin layer is formed on a first transparent substrate. Next, the photomask is placed on the first light curing resin layer. The first light curing resin layer is irradiated and cured with incident light through the photomask and the light blocking structures to have a first curing level and a first refractive index. The first curing level and the first refractive index, corresponding to each other, are periodically distributed. Finally, the photomask is removed from the first light curing resin layer to form an optical waveguide with the first light curing resin layer having the first curing level that is periodically distributed and the first transparent substrate.

Abstract: A method for preparing organic light emitting diode (OLED) by using thermal transfer film is revealed. A first transfer layer on a thermal transfer film is transferred onto a substrate by thermal transfer printing for overcoming shortcomings of the conventional vacuum evaporation including complicated processes and low material efficiency. Only less than 50% material reaches the substrate after the vacuum evaporation.

Abstract: A thermal transfer film for preparing Organic Light Emitting Diode (OLED) and a method for preparing the same are revealed. A heat resistant layer and a functional layer are disposed on a base layer respectively by coating. And a transfer layer is arranged over the functional layer. The transfer layer is heated by a thermal print head (TPH) and then is transferred onto a substrate. During the conventional vacuum evaporation used for preparing the OLED, material that reaches the substrate is less than 50%. Compared with the vacuum evaporation, the thermal transfer film and the method for preparing the same solve the problem of low material efficiency.

Abstract: A method for continuously preparing organic light emitting diode (OLED) by using thermal transfer film is revealed. At least two thermal transfer layers are transferred onto a substrate in turn by thermal transfer printing for overcoming shortcomings of the conventional vacuum evaporation including complicated processes and low material efficiency. Only less than 50% material reaches the substrate after the vacuum evaporation.

Abstract: A pixel structure of an electroluminescent display panel having a first sub-pixel region and a second sub-pixel region is disclosed. The pixel structure includes a first organic light emitting layer disposed in the first sub-pixel region and the second sub-pixel region. The first organic light emitting layer is a single layered organic light emitting layer made of one single organic light emitting material. A cavity length of the first sub-pixel region is shorter than a cavity length of the second sub-pixel region so as to enable the first sub-pixel region and the second sub-pixel region to respectively provide a first primary color light and a second primary color light. A peak wavelength of the second primary color light is larger than a peak wavelength of the first primary color light.
