  • A new plasma display panel sustaining driver using single side sustaining technique with a dual resonant method is proposed in this paper. Since this circuit enables to keep device voltage stress same as the prior circuit, it can be a low cost circuit compared to a conventional driver. To integrate the sustaining function into one side with a single power source in the driver, a charge pump method is adopted to make negative sustaining voltage and to achieve dual resonant energy recovery on the sustaining modes.

  • To improve the efficiency of PDP TV, it should minimize the power losses transpired during AC-to-DC power conversion and PDP driving process. Generally the input power supply for PDP driving employes a two-stage power factor corrected converter, and it needs additional DC-to-DC converters to supply driving power for reset circuit ed sustain driver, which has high power consumption. However, such a circuit configuration has a difficulty for the PDP market requires low cost. To alleviate this problem, a new circuit composition is presented. It integrates input power supply with reset and sustain driver in a single power stack The input power supply of the proposed circuit has a single-stage structure to minimize power conversion loss, and it directly supplies power to the sustain driver so as to reduce the system size and cost.

  • In this paper, a cost-effective PDP driving circuit using the transformer network is proposed. Compared with the previous works, the half-bridge type energy recovery circuit recovers the reactive energy not to the capacitor but to the source. A single sustain board architecture removes the blocking switches which are placed on the discharge path in parallel, thus reducing the number of devices. A simple reset circuit generates the same waveforms as the previous approaches. The circuit configuration and modified driving waveforms are compared with the previous works. The validity of the proposed simplified driver is verified through tests using a 6-inch panel.

  • 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.

  • A low cost PDP sustain power supply is proposed based on flyback topology. By using Boundary Conduction Method(BCM) to control input current regulation, DCM condition can be met under all load conditions. Another feature of the proposed method is that a excessive voltage stress due to the link voltage increase can be suppressed by removing link capacitor and suggest new 'Level-shifting switch driver'. this new gate driver is improved 66% of efficiency than switching loss of a existed push-pull amplifier. The proposed converter is tested with a 400W(200V-2A output) prototype circuit.

  • A novel priming discharge technique in which the ramp shaped priming pulse is superposed on the sustain period so that the entire plasma display panel (PDP) is discharged at the same time with a single drive circuit is proposed. From the experimental results, it is ascertained that the priming discharge is ignited only in a pixel in which sustain discharge does not occur and it has been understood that the priming pulse hardly influences the sustain discharge. Moreover, high-speed driving with address pulse widths of 0.7[${\mu}s$] was achieved and a wide address voltage margin of 40[V] was obtained by using the drive method applied the proposed priming discharge technique. In these results, full-HDTV PDP with 1080 horizontal scanning lines can be driven without decreasing the brightness and the possibility of the commercializing is also high because this technology is designed for using the commercialized driver IC.
