Abstract

이 발명은 형광막층을 이용한 PLZT 표시 장치에 관한 것으로서, 기존의 PLZT 광 셔터층 윗면에 형광막층을 형성시키고 PLZT층 후면에 형광막층의 여기원을 두어 PLZT 층을 구동하는 전극에 의해 여기원의 투과 정도를 조절함으로써 전면의 형광막층에 영상을 형성시킬 수 있도록 하여 기존의 LCD등의 평면 표시 장치에 비해 시야각이 넓고, 색재현 범위로 넓으며, 에너지 변화 효율이 높은 형광막층을 이용한 PLZT 표시 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PLZT display device using a fluorescent film layer, wherein a fluorescent film layer is formed on top of an existing PLZT optical shutter layer and an excitation source of the fluorescent film layer is placed on the back of the PLZT layer to transmit the excitation source by an electrode driving the PLZT layer. By adjusting the degree, the image can be formed on the fluorescent layer on the front side, so that the viewing angle is wider than the conventional flat panel display such as LCD, and the color reproduction range is wider, and the PLZT display device uses the fluorescent layer with high energy change efficiency. It is about.
