    Abstract: Disclosed is a white LED device using a multi-package. The white LED device maximizes the efficiency of a green LED in the yellow gap to minimize a deviation in performance between the other color chips, in comparison with conventional white LED devices using RGB multi-chips. In addition, deviations in temperature, current and droop characteristics between the chips can be minimized, contributing to the simplification of a driving circuit. Therefore, the white LED device is suitable for commercialization. Furthermore, the white LED device has a higher color rendering index (Ra) (>80) than conventional white LED devices having single-package structures. The correlated color temperatures of the white LED device are controllable in the range of 2,700 to 12,000 K. The white LED device can express abundant colors for emotion lighting and can emit white light with high efficiency.

    Abstract: A flat panel display can include a transparent substrate, a light emitting device formed on a surface of the transparent substrate, and a prism sheet formed on the other surface of the transparent substrate and having a plurality of polygonal protruding members having lengthwise axes parallel to one another to direct light output from the light emitting device in a predetermined direction. The sum of the thickness of the transparent substrate and the thickness of a portion of the prism sheet excluding the polygonal protruding members can be about 0.1 to about 0.5 mm.

    Abstract: An organic electroluminescence (EL) display device assembly includes a substrate, an organic EL portion, an optical loss prevention layer, and a fine space layer. The organic EL portion has a first electrode layer, an organic luminescent layer, and a second electrode layer which are each patterned and stacked on the upper surface of the substrate. The optical loss prevention layer is used to increase light bleeding efficiency. The fine space layer is formed between the optical loss prevention layer and a layer facing the optical loss prevention layer and is filled with a gas or evacuated.

    Abstract: A photolithography method includes applying to a substrate a coating of a film forming composition containing a bonding resin and a film forming material and drying to form a film; selectively coating the film with a photosensitive composition including a photosensitizer to form a film pattern; exposing the film with the film pattern; and developing the film. Therefore, a film in a pattern and having excellent characteristics can be manufactured easily and efficiently. The photolithography method can be applied to any product which requires the formation of a film in a pattern.
