する。In particular, it is considered as the most promising candidate for a direct-viewing type HDTV display device with a large screen. Further, in recent years, display of interlaced signals has been required along with full colorization. By the way, such a flat-panel display device generally displays electric charges accumulated between electrodes by causing discharge and emission under a predetermined voltage, and its general display principle is explained by its structure and operation. A brief description will be given below.

く恐れがある。That is, a well-known plasma display device (AC type PDP) uses a two-electrode type for performing selective discharge (address discharge) and sustain discharge with two electrodes, and a third electrode. There is a three-electrode type in which the address discharge is performed. On the other hand, in a plasma display device (PDP) that performs color display that performs gradation display, the phosphor formed in the discharge cell is excited by the ultraviolet rays generated by the discharge, but this phosphor is simultaneously generated by the discharge. It has the drawback of being susceptible to the impact of positively charged ions.
In the above-mentioned two-electrode type, since the phosphor directly hits the ions, the life of the phosphor may be shortened.

が発生している。By the way, in the above-mentioned conventional display method, especially the interlaced display method, the sustain discharge is applied to all of the Y-side electrode groups constituting the subfields not selected for display. Since the discharge pulse is applied during the period, the electric charge is applied to the capacitance C formed between the paired Y-side electrode and X-side electrode in each pixel portion of the flat panel display device. Since a charging / discharging operation of accumulating and discharging is executed, extra power is consumed accordingly.

Therefore, although it does not become a problem so much, charging and discharging between the electrodes in the non-selected pixel portion in each pixel portion can be ignored because the number of pixel portions is large. However, the power consumption of the flat panel display device has been increased.
