20090097225 | THIOGALLATE PHOSPHOR AND WHITE LIGHT EMITTING DEVICE EMPLOYING THE SAME - The present invention relates to a thiogallate phosphor which is excited by ultraviolet or blue light to emit light with a relatively longer wavelength than that of the ultraviolet or blue light. The phosphor is expressed as a general formula of (A | 04-16-2009 |
20090102354 | RED PHOSPHOR, METHOD FOR MANUFACTURING THE SAME AND LIGHT EMITTING DIODE FOR USING THE SAME - The present invention provides a red phosphor, a method for manufacturing the red phosphor and a light emitting device using the red phosphor, in which the red phosphor is expressed as a chemical formula of (Ca,Sr) | 04-23-2009 |
20090180273 | LIGHT EMITTING DEVICE AND LCD BACKLIGHT USING THE SAME - The present invention provides a light emitting device which comprises blue and red light emitting diode (LED) chips and at least one phosphor for emitting green light by means of light emitted from the blue LED chip, and an LCD backlight including the light emitting device. According to the light emitting device of the present invention, uniform white light can be implemented and both high luminance and wider color reproduction range can also be obtained. Accordingly, an LCD backlight for uniform light distribution on an LCD as well as low power consumption and high durability can be manufactured using the light emitting device. | 07-16-2009 |
20110001091 | PHOSPHOR, METHOD FOR MANUFACTURING THE SAME, AND LIGHT EMITTING DIODE - A phosphor is formed with a glass coating layer on a surface of a phosphor grain to have improved moisture and/or thermal stability. A method for manufacturing the phosphor comprises preparing phosphor gains excitable by light, and forming a glass coating layer on a surface of each phosphor grain. The glass coating layer may be formed by mixing the phosphor grains with a glass composition; heat-treating a mixture of the phosphor grains and the glass composition to make the glass composition melt and surround the phosphor grains; and cooling and breaking the heat-treated mixture to provide phosphors, each comprising the phosphor grain having the glass coating layer formed on a surface of the phosphor grain. | 01-06-2011 |
