We propose a new driving technology of PDPs, which enables to decrease the sustain voltage of conventional technology by half without lowering the gas discharge voltage, and also to cut down the number of MOS-FETs. Consequently, the cost of the driver circuit containing sustain circuit, scan driver IC and power supply can be greatly reduced.

A new plasma display technology called ALIS “Alternate Lighting of Surfaces” method which improves the resolution and brightness at the same time has been developed. By using this technology, more than 1000 numbers of scanning lines corresponding to the HDTV broadcasting can be achieved with a number of electrodes which is almost equal to present panel of 480 scanning lines, and also the brightness goes up about 1.5 times. 42 inch prototype panel with the resolution of 1024 1024 realized the brightness of 500cd/m2 and power consumption of 250W.

Abstract— When moving images are displayed on color plasma displays, motional artifacts such as dynamic false contours with disturbances of gray scales and colors are often observed. Reduction of the disturbances is essential to achieve PDPs with acceptable picture quality for TV use. The moving‐picture quality can be improved to some extent by using an equalizing‐pulse technique which augments or suppresses light‐emission to compensate for the lack or surplus from the original signal. The disturbances, however, become significant as the speed of motion increases. In order to reduce the disturbances, the equalizing pulses are weighted according to the speed and direction of motion. The improvement can be enhanced further by combining the technique with a modified‐binary‐coded light‐emission‐period scheme. Disturbance is thus reduced by 82 dB. The technique is applicable to images moving at any speed in any direction. It can also be used for any pixel arrangement and any light‐emission scheme.
