摘要:
A method for driving a gas discharge display panel consists of the steps of applying a writing pulse on a specific display electrode line selected from display electrode lines arranged side by side in the panel, applying a scanning pulse on a specific scanning electrode line selected from scanning electrode lines which are arranged side by side and cross the display electrode lines to produce writing gas discharge in cooperation with the writing pulse in a specific discharge cell arranged at an intersection space between the specific display electrode and the specific scanning electrode line, and applying a series of maintaining pulses subsequent to the scanning pulse on the specific scanning electrode during only a maintaining period to produce maintaining gas discharge subsequent to the writing gas discharge in the specific discharge cell, the maintaining gas discharge being intermittently produced in synchronism with the maintaining pulses. The scanning pulse is applied in synchronism with the writing pulse. The maintaining gas discharge is stopped without applying any pulse after the maintaining period passes.

摘要:
An optical filter made of inorganic material for red light which transfers red light and absorbs all of the other colored lights can be realized by sticking an inorganic mixture powder pasted by mixing with screen oil on a glass substrate and firing it, which mixture includes sulfates of cooper, alkali metal and alkali earth metal. The contrast of picture displayed on a display device can be extremely increased by reducing the reflection of incident ambient light without the reduction of brightness on account of the application of the above optical filter onto the displaying screen thereof.

An optical filter made of inorganic material for blue light which transfers blue light and absorbs all of the other colored lights can be realized by sticking an inorganic mixture powder pasted by mixing with screen oil on a glass substrate and firing it, which mixture includes transparent glass material powder and a combination of oxides of cobalt and aluminum. The contrast of picture displayed on a display device can be extremely increased by reducing the reflection of incident ambient light without the reduction of brightness on account of the application of the above optical filter onto the displaying screen.

An optical filter made of inorganic material for green light which transfers green light and absorbs all of the other colored lights can be realized by sticking an inorganic mixture powder pasted by mixing with screen oil on a glass substrate and firing it, which mixture includes oxides of co- ball and either of chrome and a combination of aluminium and chrome. The contrast of picture displayed on a display device can be extremely increased by reducing the reflection of incident ambient light without the reduction of brightness on account of the application of the above optical filter onto the displaying screen.
