Enhancement of the Bright Room Contrast Ratio in a Plasma Display Panel

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.
