Title (EN) PHOSPHOR HAVING HIGH COLOR REPRODUCIBILITY COATED WITH 550-600 NM LIGHT ABSORBER, AND LED USING SAME
(FR) LUMINOPHORE AYANT UNE GRANDE REPRODUCTIBILITÉ DE COULEUR, REVÊTU D'UN AGENT ABSORBANT LA LUMIÈRE DE 550 À 600 NM, ET DEL UTILISANT CE LUMINOPHORE
(KO) 550~600NM 광흡수제가 코팅된 고색재현성 형광체 및 이를 이용한 LED
Abstract:
(EN) The present invention is characterized by providing: a phosphor having high color reproducibility, the color reproducibility of which has been increased by coating a violet 0.1-50 nm oxide and acetate, which is a yellow light absorption material, on a green or red phosphor; and a device for manufacturing an LED. According to the present invention, fine particles are used, and thus it is possible to minimize a reduction in luminance even when a large amount is used. The phosphor of the present invention can absorb unnecessary light in the 560-600 nm band to achieve high color reproducibility, and can achieve a color gamut equal to or greater than NTSC 100%, and a DTI redundancy ratio of 100%.
(FR) La présente invention est caractérisée en ce qu'elle concerne : un luminophore ayant une grande reproductibilité de couleur, dont la reproductibilité de couleur a été renforcée par application d'un oxyde et acétate violet de 0,1 à 50 nm, qui est un matériau absorbant la lumière jaune, sur un luminophore vert ou rouge. L'invention concerne également un dispositif qui permet de fabriquer une DEL. Selon la présente invention, des particules fines sont utilisées, de sorte qu'il est possible de réduire à un minimum une réduction de la luminance même lorsqu'une grande quantité est utilisée. Le luminophore de la présente invention peut absorber la lumière non nécessaire dans la bande de 560 à 600 nm afin d'obtenir une grande reproductibilité de couleur, et peut obtenir une gamme de couleurs supérieure ou égale à NTSC de 100 %, ainsi qu'un taux de redondance du DTI de 100 %.
(KO) 본 발명은 노란색 흡광제(Yellow light absorption materials)인 보라색의 0.1~50nm 의 산화물 및 초산염을 녹색 또는 적색 형광체에 코팅하여 색재현성을 높인 고색재현성 형광체 및 이를 이용한 LED 제조 장치를 제공하는 것을 특징으로 한다. 본 발명에 따르면 미세입자를 사용하여 많은 양을 사용하여도 휘도 저하 최소화 가능하다. 본 발명의 형광체는 560~600nm대의 불필요한 광을 흡수하여 고색재현이 가능하며 NTSC 100%이상의 색재현율 및 DTI 중첩비 100% 가능하다.
