42.2: Using the Selective‐Reset to Achieve a “Real Black” with 50‐in. Full HD PDPs

“Real black” plasma display panels (PDPs) having a background luminance of zero cd/m2 must be realized to obtain high picture quality. PDPs, however, must have reset discharges to initialize cell conditions, regardless of expressing any of the gray levels. The light emission from the reset discharges becomes a background luminance, degrading the picture quality having low luminance levels. A technique of substituting the role of the reset discharges is proposed for 50-in. full-HD PDPs. with this technique an infinite dark-room contrast ratio is obtained. However, it has the problem of the discharge delay. A solution to this was proposed by using the frame reset or the minimum surface reset discharge and selective reset.

13.3: Using New Driving Method to Reduce Data IC Heat, with the Single Scan Mode, in a 50-In Full HD PDP

In order to improve image quality, there is a need for high definition, which is an increase in vertical lines. However, with such an increase, the data IC heat becomes an issue. The data ER circuit is used to solve this problem. We can eliminate the data ER circuit that is used by using a linear-subfield driving, a new data switching algorithm, and a new subfield mapping in a 50-in full HD PDP with single scan mode.

Improvement of the sustain‐driving characteristics of AC PDP by changing the position of the inductor

Abstract The characteristics of the sustain‐driving circuit were examined in this paper. The sustain‐driving circuit is in charge of the most important part of PDP driving because it manages most of the power consumption in the PDP. A couple of gate‐driving circuits for the sustain‐driving circuit were introduced in this paper, and a new driving circuit was also proposed. This new circuit is more cost‐effective and has a simpler PCB layout compared to the conventional one. Some additional driving advantages were noted as well.

The trophy (talented role‐playing technology with a dual polarity sustainer in hybrid mono board) driving method

Abstract We have developed a new driving method named TROPHY(Talented Role‐playing Technology with Dual Polarity sustainer in Hybrid Mono board). In this method, the sustain voltage is partially compared to the conventional method and the number of power sources is reduced by voltage level unification during the reset, address and sustain period. The hybrid mono board was especially developed to implement those technologies. Through this, we can lower the cost with the TROPHY compared to the conventional one. It is a suitable technology to improve the reliability of circuit and image sticking problem. We can also reduce the number of driving boards and the EMI problem compared with those of the conventional method.
