Emission Properties of P-ELD by Thickness of Phosphor and Insulating layer
절연층 두께 변화에 따른 분산형 ELD의 발광특성
Abstract
Light-emitting diode(LEDs), diode arrays, and phosphor display panels are finding increased use in a variety of commercial applications. Present and anticipated application of these devices include solid state indicator and display systems. In this work, Phosphor based on ZnS:Cu are used. Relation by luminance with the thickness of insulating layer and phosphor layer are discussed. Increased thickness of insulating layer are stable on voltage to 300V. By considering thickness and voltage, optimal structure and thickness are investigated. In order to maximize even surface emission, various sieving processes are introduced. 150cd/m
