LED分类方法、LED分类装置、LED分类程序及记录介质
摘要：
LED分类装置(21)中，若将发出1次光的LED元件和被1次光激励而发出波长比1次光要长的2次光的荧光体进行组合的LED的1次光的色度在规定范围内，则将该LED作为用于液晶显示装置的背光源的对象进行分类。系数计算部(26)和校正色度计算部(27)对作为分类对象的所有LED计算出假设1次光透过液晶显示装置的滤色片而得到的色度的校正值，从针对作为分类对象的所有LED得到的色度分别减去该校正值，从而对色度进行校正。色度等级分类部(28)基于校正色度对LED进行色度等级分类。
摘要（英）：

An LED obtained as a combination of an LED element that emits first light, and a fluorescent body that is excited by the first light and caused to emit second light of a longer wavelength than the first light is classified by an LED classification device as suitable for use in the backlight of a liquid-crystal display device a long as the chromaticity of the first light of the LED is within a predetermined range. A coefficient calculator (26) and a corrected-chromaticity calculator (27) calculate, for all the LEDs classified as suitable, a chromaticity correction value obtained based on the assumption that the first light has passed through a color filter of the liquid-crystal device, and correct the chromaticity by subtracting each of the correction values from the chromaticity obtained for all of the LEDS classified as suitable. A chromaticity-rank classification unit (28) classifies the LED by chromaticity rank on the basis of the corrected chromaticity.
