A light emitting diode (LED) lighting module is provided including an LED array, and at least one of a diffusing portion and a reflecting portion. The LED array, equipped with at least one LED, may include a side wall which surrounds the at least one LED. The diffusing portion may be detachably coupled to the LED array and may include a diffusion plate which diffuses light emitted from the at least one LED The reflecting portion may be detachably coupled to one of the LED array and the diffusing portion and may reflect light emitted from the at least one LED. The LED array may be selectively coupled with the diffusing portion, the reflecting portion, or both the diffusing portion and the reflecting portion.

Light emitting diode lighting module

An organic light-emitting diode ('OLED') device includes an organic light-emitting substrate part and a protective cover part. The organic light-emitting substrate part includes a base substrate and an OLED display portion formed on the base substrate to display an image. The protective cover part includes a first frit glass disposed on the OLED display portion to cover the OLED display portion, and a second frit glass formed around a periphery of the first frit glass. The second frit glass is connected to the first frit glass.

An organic electroluminescent display having better photoluminescence efficiency includes a first electrode, an organic light-emitting layer, and a second electrode sequentially disposed on a first surface of an insulating substrate, and a plurality of convex patterns disposed on a second surface of the insulating substrate opposite to the first surface and spaced apart from each other, and which are formed of a transparent sealant having a viscosity of 5,000 to 150,000 cp and comprised of an epoxy- or acrylate-based resin, together with a plurality of concave patterns interposed between the convex patterns.

Organic electroluminescent display and method of manufacture

A manufacturing method for manufacturing a display device includes forming a discontinuous organic layer on at least one of a cover substrate and an insulating substrate provided with a display device element, arranging the insulating substrate and the cover substrate with facing each other for the organic layer to be interposed therebetween, and assembling the cover substrate and the insulating substrate by pressing the substrates together.

Manufacturing method for display device, manufacturing apparatus for the same and display device made by the same

An optical waveguide includes a linear metallic thin film having a light delivering unit coupled to one end thereof, through which light is incident; and at least more than two dielectric layers surrounding the metallic thin film. In the optical waveguide, an effective refractive index and a propagation loss in the metallic thin film is reduced so that long-range light transmission is realized. Further, a loss of light caused by the coupling to optical fiber, which is coupled to one end of the metallic thin film, is simultaneously reduced.

Optical waveguide

An optical waveguide for transmitting a surface plasmon-polariton wave includes a metallic thin film formed to have a triangle-shaped cross-section; and a pair of first and second dielectric layers coupled to each other such that the opposing surfaces thereof come in contact with each other, with the metallic thin film interposed therebetween, the first and second dielectric layers having a different refractive index and a positive or negative dielectric constant.
