A planar display device whose display panel main body can be easily separated from a chassis member upon disposal without preparing large equipment and a special tool. In the planar display device wherein the PDP panel main body () and the chassis member () are adhered by a two-sided tape (), a wire () is previously incorporated for separating the PDP panel main body () from the chassis member () by cutting and peeling the double-sided tape.

Planar display device

A display has a panel, and first and second electrodes. The first and second electrodes define a matrix of cells on the panel. The second electrodes, which correspond to lines of the cells, are scanned to select the cell lines one by one. The first electrodes are driven to set display data for a selected one of the cell lines. The display also has a sequence setting unit for setting sequences of scanning the second electrodes, and a sequence selection unit for selecting one of the sequences that minimizes the current and power consumption of a first-electrode driver without deteriorating the quality of the displayed images.

In an AC-type PDP including first and second sustain electrodes extending along a line direction via a discharge slit; a discharge space; a dielectric layer coated on the first and second sustain electrodes, and an address electrode orthogonal to the first and second sustain electrodes via the dielectric layer, wherein the first and second sustain electrodes comprise first and second belt-like first and second metal electrodes thereon, respectively, where the first and second metal electrodes are narrower than the first and second transparent electrodes, respectively, wherein the first metal electrode is located on an edge apart from the discharge slit; and the second metal electrode is located on another edge near to the discharge slit. Moreover, then, a distance between the second sustain electrode and said address electrode may be smaller than a distance between said first sustain electrode and said address electrode. A gap between the second sustain electrode and the address electrode may be smaller than a clearance between the first sustain electrode and the address electrode. A rise time of a first sustain pulse which makes the second sustain electrodes negative with respect to the first sustain electrode is preferably slower than a second rise time of a second sustain pulse which makes the second sustain electrodes positive with respect to the first sustain electrode.

AC-type plasma display panel and its driving method

A method for driving a plasma display panel includes carrying out an erase address operation when a display on the screen is renewed. The erase address operation includes the steps of carrying out an address preparation operation for producing the wall charge in all the discharge cells through a first step of generating a discharge only in a discharge cell in an ON-state and a second step of generating a discharge only in a discharge cell in an OFF-state, and carrying out an operation for selectively erasing the wall charge in a discharge cell other than a discharge cell corresponding to data of the image to be displayed.

Method for driving a plasma display panel

A multiple-terminal communication equipment comprises a data communication unit, an information processing unit, and a data input/output unit, for realizing radio communication between at least two terminals. The multiple-terminal communication equipment transmits, before transmitting data from one terminal, a transmission disabling code for disabling data transmission of the other terminals, and after completely transmitting the data from the one terminal, a transmission enabling code for canceling the transmission disabled states of the other terminals. This arrangement is capable of smoothly and correctly communicating data between a plurality of terminal equipments.
