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 the electric resistance of signal electrodes.

Abstract: A plasma addressing electro-optical device which can be driven at a comparatively low voltage is disclosed. A plurality of signal electrodes (L) are formed on an inner surface of an upper glass substrate (4). A plurality of plasma electrodes as anodes (A) and cathodes (K) are formed on an inner surface of a lower glass substrate (7) and extend perpendicularly to the signal electrodes. A liquid crystal layer (6) is filled between the upper glass substrate and an intermediate dielectric sheet (3). A plasma chamber (11) is provided between the dielectric sheet and the lower glass plate, and ionizable gas is enclosed in the plasma chamber. The gas is selectively ionised by discharge between the cathodes and the anodes, and taking the discharge regions, in which the ionized gas exists locally, as scanning units, the liquid crystal layer positioned at intersecting positions between the signal electrodes and the discharge regions is driven. A driver circuit for such driving includes an invertor circuit (22) which inverts an image signal to be applied to the signal electrodes and a potential to the anodes at a time with reference to a potential of a substantially middle level of a driving voltage for the signal electrodes.

The plasma cell has discharge channels 5 arranged in rows, and on the other hand, the liquid crystal panel is provided with signal electrodes 4 arranged in columns; and an image plane 6 is constituted by defining image elements 6 in the intersections of the discharge chambers 5 and the signal electrodes 4. A scanning circuit 2 is connected to the discharge channels 5, and the discharge channels 5 are successively discharge-driven all over the image plane for selecting the image elements 6 for each row through the dielectric sheet. A signal circuit 3 is connected to the signal electrodes 4 so as to drive the signal electrode 4 in synchronization with the discharge drive and also on the basis of the image data for one image plane and to write the signal voltage onto the selected image elements 6. An arithmetic circuit 8 calculates for each row the effective potential difference produced between the adjacent signal electrodes 4 on the basis of the image data that have been input from the outside, and integrates them all over the image plane. A correction circuit 9 corrects the signal voltage to be supplied to the respective signal electrodes 4 on the basis of the result of integration, and reduces the cross talk attributable to the potential difference between adjacent signal electrodes 4.
