A display apparatus includes a display panel, a panel substrate including a data line driver, a controller connected to the panel substrate, and a connection unit provided in the panel substrate. The controller selects M signal lines from N signal lines (M is a natural number satisfying M&#x2266;N) in accordance with a frame rate of a video data, and transmits M-phase video data to the panel substrate via the selected M signal lines. The data line driver controls the switching circuits of the connection unit in accordance with the frame rate of the video data to connect the M signal lines via which the video data is transmitted, to the data lines, and sequentially selects the M data lines to supply each piece of the video data transmitted via the M signal lines to each pixel connected to the selected M data lines.

Display apparatus

A display device comprising a display panel, a plasma driving circuit, a correcting circuit and a display driving circuit. The display panel has a laminated structure consisting of a display cell with signal electrodes arrayed in columns, a plasma cell with discharge channels arrayed in rows, and a dielectric sheet interposed therebetween. The plasma driving circuit sequentially drives the discharge channels to address the display cell line-sequentially via the dielectric sheet, and the correcting circuit processes picture signals through a corrective arithmetic operation. And the display driving circuit supplies the processed picture signals to the signal electrodes in synchronism with the line-sequential addressing, and then writes the picture signals in pixels prescribed at the intersections of the signal electrodes and the discharge channels. The correcting circuit executes such a process as to emphasize the difference between the picture signals supplied to mutually adjacent signal electrodes. This display device is adapted to eliminate, in driving the plasma addressed display panel, inter-pixel crosstalk or data diffusion derived from the thickness of the dielectric sheet.

Display device

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.

Signal electrodes for plasma addressed display system

A plasma addressed electro-optical display with a high contrast, having a first substrate having a plurality of discharge electrodes formed thereon; a dielectric layer disposed apart from the first substrate by a predetermined distance; a plasma cell formed by sealing the peripheries of the first substrate and the dielectric layer with a sealing portion; and a second substrate disposed opposite to the dielectric layer and having data electrodes intersecting the discharge electrodes on the surface thereof, wherein the plasma cell and the second substrate are stacked in such a manner that an electro-optical material layer is interposed between the plasma cell and the second substrate so that the plasma addressed electro-optical display is formed, and a light source is disposed adjacent to the second substrate.
