Title (EN) FULL-COLOR LED DISPLAY PANEL
(FR) PANNEAU D'AFFICHAGE À DEL DU TYPE MULTICOLORE
(JA) フルカラーLED表示パネル
Abstract:
(EN) The present invention is provided with: an LED array substrate (1) which is formed by disposing, on a substrate, a matrix of a plurality of LEDs (3) capable of radiating light in a wavelength range from ultraviolet to blue; a plurality of fluorescence emitting layers (5) which are juxtaposed side by side on the LEDs (3) so as to correspond to the three primary colors of light and which are excited by excitation light radiated from said LEDs (3) so as to have the respective wavelengths thereof converted into fluorescence of the corresponding colors; and an excitation light cut-off layer (8) which is disposed so as to cover the fluorescence emitting layers (5) in order to cut off the excitation light.
(FR) La présente invention comprend : un substrat de réseau de DEL (1) qui est formé en disposant, sur un substrat, une matrice d'une pluralité de DEL (3) en mesure de rayonner de la lumière dans une plage de longueurs d'onde allant de l'ultraviolet au bleu ; une pluralité de couches d'émission de fluorescence (5) qui sont juxtaposées côte à côte sur les DEL (3) de manière à correspondre aux trois couleurs primaires de lumière et qui sont excitées par une lumière d'excitation rayonnée en provenance desdites DEL (3) de manière à avoir leurs longueurs d'onde respectives converties en fluorescence des couleurs correspondantes ; et une couche de coupure de lumière d'excitation (8) qui est disposée de manière à recouvrir les couches d'émission de fluorescence (5) afin de couper la lumière d'excitation.
(JA) 本発明は、紫外から青色波長帯の光を放射する複数のLED(3)を基板上にマトリクス状に配置したLEDアレイ基板(1)と、光三原色に対応させて複数の前記LED(3)上に並べて設けられ、該LED(3)から放射される励起光によって励起されて対応色の蛍光に夫々波長変換する複数の蛍光発光層(5)と、前記蛍光発光層(5)上を覆って設けられた前記励起光を遮断する励起光カット層(8)と、を備えたものである。
