    摘要: A large area visual display matrix of ultra-violet initiated individual small gas discharge elements. Each element remains in a discharge condition until the voltage applied to a common anode is turned off and for this reason the matrix requires no associated memory or storage property to remain on as long as information is to be displayed. The matrix generally comprises, in order, an electrically conductive cathode with a low work function material photo-emissive coated thereon which emits electrons when irradiated by U.V. light, an insulating medium with apertures therein, individual anodes with holes therein the holes being axially aligned with the apertures in the insulating medium, a voltage supply for each anode, the foregoing elements being sandwiched between a base and a U.V. permeable cover, and a suitable gas filling for the apertures. A source of U.V. light is directed at the portion of the visual display it is desired to illuminate.
