An experimental real-time color-TV display with a DC gas-discharge panel

An experimental color-TV picture display is presented on a dc gas-discharge panel which is based on the Burroughs' "self-scan" panel. An array of 127 × 160 dots of three color phosphors were formed on the inner surface of the front glass plate to reproduce color pictures. A thinner center sheet of soda glass with a thickness of 0.25 mm was used so that the phosphors might be excited effectively by the UV radiation generated from the negative glow of the discharge. Based on our vacuum-spectroscopic measurements on various phosphors, Y
