Gas-Discharge Color Panel for TV Display with Ultra-Low Reflectance

摘要

Low contrast is a problem with a gas-discharge type panel intended for a flat-panel TV. To resolve it, it was proposed that the panel be provided with color filters for each color cell, so as to reduce the reflectance without significantly degrading the luminance. Panels showing a luminance degradation 30% and of reflectance 3% or so have been obtained. A TV picture display using these panels had a contrast 3 to 7 times as great as conventional panels. New R and B filters have almost satisfactory characteristics, but the G filter has room for further improvement. With the panel, if the filter characteristics are considered, gases showing a small emission of visible light, for example, Ne type gases, may also be used. The filter and white glass materials described can also be used in other types of gas discharge panels and in CRT and other devices.
