49.4: A New Driving Technology for PDPs with Cost Effective Sustain Circuit

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.

High-Resolution Interlaced Addressing for Plasma Displays

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.

ALIS method for high-resolution color PDPs

— This paper describes the Alternate Lighting of Surfaces (ALIS) method as a promising drive technology which can lead to high-resolution plasma-display panels (PDPs). This technology provides a resolution of more than 1000 scanning lines without lowering luminance, thus enabling the essential requirements of HDTV. Moreover, it allows the number of scanning electrodes to be halved in comparison with the conventional method, as well as the circuit scale to be minimized due to the use of the single scanning drive. The ALIS method is expected to be a key technology that will help PDPs penetrate the TV market.
