Abstract

본 발명은 피엘지티(PLZT)평판 디스플레이 패널에 관하여 개시한 것이다.The present invention discloses a PLZT flat panel display panel.

본 발명에 의한 피엘지티(PLZT) 평판 디스플레이 패널은 형광체막과 피엘지티(PLZT)층 및 편광판을 다층으로 적층 형성하여 형광체의 발광과 PLZT층의 라이트 밸브(light valve)역할을 조합시킨 것으로, 형광체의 여기원을 두어 PLZT층을 구동하는 전극에 의해 형광체의 발광빛 투과정도를 조절하여 영상을 표시함으로써 칼라 디스플레이를 가능하도록 한 동시에색재현 범위 및 휘도를 향상시킬 수 있도록 한 것이다.The PLZT flat panel display panel according to the present invention is formed by stacking a phosphor film, a PLZT layer, and a polarizing plate in multiple layers to combine the light emission of the phosphor and the light valve role of the PLZT layer. An excitation source of the PLZT layer is used to control the emission light emission of the phosphor to display an image, thereby improving color gamut and improving luminance.
