In a light emitting diode package or a light emitting diode, a cover body having an opening with a reflecting surface is attached on an upper portion of a base body on which a light emitting diode element is mounted. The base body is formed of alumina ceramics having a pore diameter of 0.10 to 1.25 .mu.m or a porosity of 10% or more, and a thermal via is formed in the base body. Accordingly, it is possible to improve luminance and heat radiating characteristics of the light emitting diode packag...

What is disclosed is an organic light emitting diode (OLED) based device which has been exposed to an environment including a mixture of gases and moisture in the form of water vapor, for a specified period of time prior to the device being encapsulated. The environment may contain oxygen, nitrogen, hydrogen, argon or atmospheric air or a combination thereof.

A method of making a light source includes the steps of forming a first optical component having a phosphor material in fixed relation to a first multilayer interference reflector, providing a second optical component having an LED capable of emitting light that excites the phosphor material, and positioning the first optical component to receive emitted light from the second optical component.

A multilayer barrier film structure of an organic EL display panel has a multilayered body formed on a surface of a supporting substrate. The multilayered body includes an intermediate film sandwiched between inorganic films. The film structure includes a sealing region provided so as to surround the multilayered body on the surface of the supporting substrate. In a method of manufacturing an organic EL display panel comprising an organic EL device and a supporting substrate, a first inorganic f...

An LED chip capping construction to enhance luminance of the LED containing a condenser capping over a chip of the LED; a condensing part of the condenser protruding through a carrier and surrounded by multiple condensing aspects; the source light from the chip passing the condenser and consistently reflected to each condensing aspect due to the medium characteristics of the condenser.

A light emitting device and the method for producing the same are disclosed. The light emitting device has at least a light emitting unit with a first electrode and a second electrode for generating a light source when powered on, a conductive element electrically coupled to the first electrode of the light emitting unit and a substrate having a carrier portion for carrying the light emitting unit and a heat dissipating portion extending from the carrier portion and electrically coupled to the s...

An electro-luminescence display device for reinforcing its strength is disclosed. In the device, an organic compound layer is provided on a substrate.
