Tedielectric layer affect on Electroluminescent cloth Brightness

Abstract

In this study, coated by knife coating gauge of 0.5 mm, 1.0mm, 1.5mm, 2.0mm way to coated with different viscosity(1000、3000、5000cP) and plus 1.5mm gauge of fluorescent powder coating, put into an auxiliary tinning silver wire, made of electroluminescent cloth, observed coating thickness and emission luminance. In the dielectric layer ratio of 4: 1, when the coating knife gauge 1.5mm, observed coating thickness and emission luminance. When the viscosity 3000cP, gauge 0.5mm, have the best brightness 21.8lux. Barium titanate powder was observed by SEM and then dispersing the case of the dielectric layer. At last 48, 72, 96 hours life test, unpackage decline is twice the brightness of the package.

摘要

本研究以4:1的水性PU與鈦酸鋇粉，調配黏稠度1000、3000、5000cP，並利用塗佈刀以隔距0.5mm、1.0mm、1.5mm、2.0mm方式去塗佈介電層，再以隔距1.5mm塗佈螢光層，製成電致發光布，觀察塗佈厚度與發光亮度，在黏度3000cP隔距0.5mm時，有最佳亮度21.8lux，並用SEM觀察鈦酸鋇粉在介電層的分散情形，最後壽命測試48、72、96小時，無封裝下降的亮度是有封裝的兩倍。
