A full color gas discharge panel is Still insufficiently bright for use as a high definition display, so increasing contrast or reducing reflectance should be regarded with more importance than increasing brightness, especially for viewing in a light illuminated room. We proposed a panel which has micro color filters coated on inner surface of the faceplate. A 25-in. panel has been developed with 512×768 cells of 0.7mm pitch. Size and power consumption of new display system is about half of these of a conventional system. A HDTV picture is displayed on the panel with the following performance ; luminance 90cd/m^2, gray level 256, contrast 50 in a 200lux environment.
