Embodiment Construction

[0046] Referring to the drawings, wherein like numerals represent like elements, figure 1 A partial cross-sectional view of an example full-color display is shown in . The front or top substrate has on its inner surface a display electrode 7 which may be combined with a transparent extension 8 covered with a dielectric material 9 whose surface is covered with a photoemissive layer 10 . In this surface are formed microchannels 11 parallel to the display electrodes. The front substrate is sealed in contact with the rear substrate 1, which contains light-emitting regions 5 on the surface of microgrooves separated by a thin barrier layer 4 and forming gas-filled channels in said microgrooves. A fluorescent material is deposited on the region 5 where it coincides with the electrode 2 covering the inner surface of the microgroove. Each adjacent light-emitting area may contain three different fluorescent colors, such as red (R), green (G), and blue (B), in a repeating manner. A pi...

Abstract

An improved AC plasma display panel structure and method of driving for improved efficiency. Gaseous discharges can tunnel or initiate in microchannels parallel to sustain electrodes in a front substrate lowering operating voltages and allowing the use of more efficient gas mixtures. A write step applies a pulse to selected first and second sustain electrodes corresponding to cells on a row that will be turned ON, and an erase step applies a voltage to first and third electrodes corresponding to cells that are to be turned OFF. Write discharges are tunneled through microchannels.

Description

technical field [0001] The invention relates to a plasma display and a method of operation for increased efficiency. More specifically, the present invention relates to full-color, high-resolution alternating current (AC) plasma displays commonly referred to as PDP (plasma display panel) monitors, which have a front or top viewing panel and a rear panel containing a gas discharge These microgrooves emit UV light and excite light-emitting phosphors on the surface of the microgrooves. Such displays are used in computer screens and TVs, but they generally operate at low frequencies compared to CRT tubes. Background technique [0002] A flat panel display is an electronic display in which a large orthogonal array of display devices such as electroluminescent devices, AC plasma display panels, DC plasma panels, and field emission displays form a flat panel display. [0003] The basic structure of an AC plasma display panel or PDP consists of two glass plates separated by an air...
