Title: Driving method of AC-type plasma display panel
Inventor: SHOJI TAKATOSHI
IPC: G09G3/288
Filed: 2002-10-26
Abstract: PURPOSE: To provide the driving method of an AC type plasma display capable of making the sustained light emission by erroneous discharge inconspicuous in a period before the power source of the display device is stabilized even when erroneous discharge is generated by the effect of residual electric charges at the time of the starting up of the display device. CONSTITUTION: In this driving method of the plasma display, the driving method of one frame is changed in a period before the power source is stabilized (the standby period of the stabilization of the power source) and in a display period. The time required for the voltage of the power source to be stabilized is, for example, about 0.5 to 1 sec. after the power source is applied (the display is started). In the field 1 in this period, one field is divided into the plurality of sub-fields (SFs), however, in the sustenance period of each sub-field, the number of repeated pulses is made smaller as compared with that in the sustenance period of each sub-field in the display period and, for example, sustaining pulses are not to be applied on scanning electrodes. As a result, even when erroneous discharge is generated by the effect of the residual electric charges at the time of start up, the sustained light emission by the erroneous discharge becomes inconspicuous in the display.
