Abstract

A plasma addressed display system with a flat panel structure comprising a display cell for displaying an image through modulation of incident light in accordance with an image signal, and a plasma cell joined to the display cell for scanning the same. The plasma cell has discharge channels arrayed in rows and generates discharges in succession to scan the display cell line sequentially. The display cell has signal electrodes arrayed in columns, and forms pixels at intersections with the discharge channels. The display cell applies an image signal in synchronism with the line sequential scanning and modulates the incident light per pixel. Pixels of two rows are defined in the discharge channel of one row. The intersections of the signal electrodes and the discharge channels are partially shielded from light with a mask in a predetermined pattern, while the remaining unmasked light transmitting portions are assigned to the pixels 11 of either row, and the image signal is applied simultaneously to the pixels of two rows by the discharge generated in the discharge channel of one row. In this system, an enhanced resolution is achieved without harmfully affecting the aperture ratio or t…
