Abstract: A plasma display device is realized which has a high set-luminous-efficacy (i.e. provides a high-brightness display image at a low power consumption) and a high light-room contrast. The luminous efficacy hs and the display discharge voltage Vs are increased by increasing the product pd in discharge, or increasing the Xe proportion aXe of the discharge. As a result the display-discharge region area ratio Ad and the display region reflectance ? can be reduced by reducing the display-electrode area Sse approximately in inverse proportion to Vs2, and thereby the set-luminous efficacy hs and the set luminance Bpons and the light-room contrast Cb are increased.

Abstract: Values of input parameters are set. Simulations are executed in parallel for individual sets of input parameters by a plurality of processors to obtain design values which are execution results. The obtained design values are compared with the design condition. Directory files are constructed for plural kinds of input parameters corresponding to design values satisfying the design condition. Accumulative distribution in the distribution of parameter input values are determined in respect of the individual kinds of input parameters. Input values of parameters to be referred are extracted on the basis of values of the accumulative distribution every kind of input parameter. The kind of input parameter, the extracted input values and the number of the extracted input values are displayed through an input interface every kind of input parameter.

Abstract: A plasma display device includes plural discharge cells each defined by a pair of first and second discharge-sustaining electrodes and an address electrode intersecting therewith. A driving method thereof includes period for addressing the discharge cells and thereby inducing address-discharge therein, and light-emission period for applying repetitive pulse voltages to at least one of the first and second discharge-sustaining electrodes such that the addressed ones of the discharge cells start and sustain main discharge depending upon the presence of the address-discharge to generate light. Second repetitive pulse voltages are applied to the address electrodes to generate pre-discharge, and rise in portions of the light-emission period during which an absolute value of a voltage difference between the first and second discharge-sustaining electrodes does not exceed 0.

A voltage is applied to at least one of the sustained discharge electrodes and the address electrode in a sustained discharge period. A sustained discharge voltage is repeatedly applied to the sustained discharge electrodes 102 and 103. The sustained discharge voltage has a voltage waveform with a rise period (Tr) from a first voltage level to a second voltage level, a sustained period (Tsus) for maintaining the second voltage level, a fall period (Tf) from the second voltage level to the first voltage level and a sustained period (Tg) for maintaining the first voltage level.

In a plasma display device for performing driving including at least an address period and a sustain-discharge period for emission display, the sustain-discharge period includes a pulse application period and an open period, a voltage of an electrode to which a relatively positive voltage is applied in a sustain-discharge electrode pair in a pulse application period immediately before the open period is set as Vsp, and the voltage of the other electrode is set as Vsn, Vsp−Vsn has a significantly negative value in the open period, and light is emitted by a discharge in the open period.

Abstract: A discharge is initiated in a cell in which an address discharge is conducted at a first timing T1 in a charge adjustment period. Next, at a second timing T2, a discharge is initiated for adjusting a wall charge in a cell where a charge remains therein because the address discharge does not occurred. Thus, some negative charges are formed in an X electrode and a Y electrode, thus preventing a false discharge from occurring in an unselected cell.

The pairs of electrodes for sustaining discharge are disposed on a same one of the pair of base plates.

A parameter and a variable are supplied from the heterogeneous coupling variational equation calculation unit into and out of a simulator A, a simulator B and a heterogeneous coupled equation thereby to form the heterogeneous coupling variational equation 1 and thus to determine a globally consistent solution.
