Abstract

An intermediate electrode is formed in a space between an X display electrode and a Y display electrode parallel thereto. A negative voltage is applied to the Y display electrode to use the Y display electrode as a cathode. A charge is stored between the Y display electrode and an intermediate electrode to create an electric field. Upon the increase of the intensity of the electric field to a sufficiently high level, an instant discharge occurs between the Y display electrode and the X display electrode and intense ultraviolet rays are produced. The fluorescent layer excited by the ultraviolet rays emits visible light. Only a narrow pulse current flows through the X display electrode and the Y display electrode, so that power consumption can be suppressed at high emission efficiency.

Description

technical field [0001] The invention relates to a plasma display panel, which is used in information processing terminals and various flat wall-mounted TV sets, and a display using the plasma display panel. Specifically, the present invention relates to a plasma display panel capable of operating with greatly improved luminous efficiency and capable of displaying images with greatly improved luminance, and to a plasma display panel using such a plasma display panel monitor. Background technique [0002] A reflective three-electrode surface discharge plasma display panel has been widely used, on which two types of transparent display electrodes formed on the same surface of a front substrate are provided. A prior art reflective three-electrode surface discharge plasma display panel is disclosed in the patent document JP 10-207419A. [0003] refer to Figure 12 , which shows a part of a known plasma display in a perspective view, showing a front substrate FS, a rear substrat...
