Abstract
A new electrode structure in a plasma display panel was designed in a way to increase the bright room contrast ratio (BRCR). The area of the black matrix pattern to get a low reflection from the panel surface was enlarged using the new electrode design concept. The electrical characteristics such as firing voltage, voltage margin and power consumption were measured. The luminance of the panel was measured and the luminous efficiency was calculated. It was found that the new electrode structure was very effective to enhance the BRCR.
플라즈마 디스플레이 패널에서 명실콘트라스트(bright room contrast ratio: BRCR)를 개선하는 방향으로 새로운 전극구조를 설계하였다. 새로운 개념의 전극을 이용하여 블랙매트릭스 패턴의 영역을 넓힐 수 있었으며 이를 통하여 패널면의 반사휘도를 낮출 수 있었다. 제작한 플라즈마 디스플레이 패널에 대하여 방전전압, 방전효율, 휘도 등을 평가하였으며 명실콘트라스트가 크게 개선됨을 확인하였다.
