摘要： A white-light emitting diode (LED) is provided that emits primary light at a wavelength that is in the range of 485 to 515 nanometers (nm), which corresponds to a bluish-green color. A portion of the primary light is converted into a reddish-colored light that ranges in wavelength from approximately 600 to approximately 620 nm. At least a portion of the converted light combines with the unconverted portion of the primary light to produce white light. A number of phosphor-converting elements are suitable for use with the LED, including a resin admixed with a phosphor powder, epoxies admixed with a phosphor powder, organic luminescent dyes, phosphor-converting thin films and phosphor-converting substrates. Preferably, the phosphor-converting element is a resin admixed with a phosphor powder in such a manner that a portion of the primary light impinging on the resin is converted into the reddish-colored light and a portion of the primary light passes through the resin without being converted. The unconverted primary light and the phosphor-converted reddish-colored light combine to produce white light. The LED is mounted in a reflector cup that is filled with the phosphor-converting resin. The LED may be mounted in either a normal or flip-chip configuration within the reflector cup.

摘要： A color, transmissive LCD uses a backlight that supplies a uniform blue light to the back of the liquid crystal layer in an LCD. The blue light, after being modulated by the liquid crystal layer, is then incident on the back surface of phosphor material located above the liquid crystal layer. A first phosphor material, when irradiated with the blue light, generates red light for the red pixel areas of the display, and a second phosphor material, when irradiated with the blue light, generates green light for the green pixel areas of the display. No phosphor is deposited over the blue pixel areas.
摘要翻译：彩色透射式LCD使用在LCD中向液晶层背面提供均匀蓝光的背光源。然后，被液晶层调制后的蓝色光入射到位于液晶层上方的荧光体材料的背面。当用蓝光照射时，第一荧光体材料对于显示器的红色像素区域产生红色光，并且当用蓝色光照射时，第二荧光材料产生用于显示器的绿色像素区域的绿色光。在蓝色像素区域上没有荧光体沉积。
