Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a gas discharge display device, and in particular to a flat panel gas discharge display device that displays information to the outside by selectively emitting light from discharge cells arranged in a matrix. The present invention relates to a plasma display device including an information display section.

A plasma display device is used as 12'Wl. An example of this type of 'AX is Japanese Patent Publication No. 10525/1983. As shown in FIGS. 4 and 5, this conventional device includes a plurality of cathode electrodes 5 (the ends of which are shown not yet separated) and which are arranged perpendicularly to the cathode electrodes 5. An insulating spacer 3 having a small hole that forms a discharge cell is sandwiched between the plurality of anode electrodes 6 and the intersection of the anode electrode 6 and the cathode electrode 5, and this is further sandwiched between the window glass 2 and the base glass 4. They were sandwiched together, the periphery was sealed in a high vacuum, and the inside was replaced with a rare gas such as Ne. These discharge cells include a display cell that is used to display discharge to the outside, and an auxiliary discharge cell that helps the display cell start discharging.By transferring the discharge of these auxiliary discharge cells one after another, the display The battery is discharged without delay to provide a flicker-free display. That is, in a DC type plasma display device, even if a voltage is applied between the anode electrode and the cathode electrode, discharge does not start immediately. The time until the discharge starts depends on the state of ionization within the discharge cell. Normally, the gas is ionized to some extent by thermal fluctuations due to temperature and light from the outside, but this ionization is caused by voltage. Therefore, unless the gas is ionized and activated by some means, it will not discharge immediately even if the voltage for display is applied, and a discharge delay will occur. It appears as a flickering light. In order to eliminate this discharge delay, preliminary discharge is performed by an auxiliary discharge cell to obtain ionized gas. Note that this auxiliary discharge cell is hidden so that it cannot be seen from the outside.
