24.4: Invited Paper: The Improvement of Ambient Contrast in Plasma Display Panel using Subtractive Mixture of Colors

Abstract

We researched to minimize the loss of luminance on display area and reflection luminance to improve ambient contrast in bright circumstance. According to the result of our research, we propose that you'd better use compliment colors on transparent dielectric layer and barrier rib of rear glass (rear panel) applying to color's being dark when mixed instead of using a black stripe pattern so as to lowering reflection luminance. We've applied this technique to 42inch VGA panel that shows reflection luminance was diminished to 63% and ambient contrast at 150-lux light was improved from 93:1 to 151:1 recording the improvements of 61% in comparison with conventional panel with black stripe; which is the best result for ambient contrast under the bright circumstance in the PDP panels are being researched.
