ADS(Address Display Period Separation) driving method has been considered to be the most appropriate driving technique for AC PDP. ADS driving method is composed of reset, address, sustain and erase period. Therefore, a long time should be allocated to an address period, which results in a reduction of brightness. To realize a high luminance and high picture quality, it is necessary to high speed addressing. However, address discharge time lag increases as the temperature decreases, which can cause the misfiring and low picture quality In this paper, the electric field effect and priming particle effect are investigated in order to reduce the address discharge time lag at low temperature. Address discharge time lag was reduced effectively when the priming particles are provided.

ADS(Address Display period Separation) driving method has been considered to be the most appropriate driving technique for AC PDPs. However when the ADS driving method is applied to the high-resolution AC PDP, the required long addressing time often becomes a problem. In this paper, we present a new waveform for reducing the addressing time and for the stable addressing discharge. In this new waveform, a wall charge acceleration pulse is applied to the common electrode right after 80us scan time. In this way, the charge generated by the addressing discharge is accelerated to the electrodes. Experiments using the wall charge acceleration pulse showed that we could stably address an AC PDP with the scan pulses having pulse width of 1 us

This paper proposes a PDS(Power Transfer Display separation) method for AC-PDP. The proposed PDS method can transfer power and perform an energy recovery by a power conversion circuit operates differently depending on the time. As a result, it uses less of components than conventional PDP power supply and sustain circuit use. Moreover, the manufacturing process can be streamlined. Therefore, the proposed method is suitable for low cost PDP module. To confirm the operation, validity and features of the proposed PDS method, experimental results from a prototype for 42-in diagonal PDP are presented.

In this paper, PDP driving circuit is designed to show the pattern of still-image with ADS (Address Display Separation) driving method. The designed circuits consist of three stages which are the image processing program, digital logic parts, and power circuits. The Image processing program is designed serial-communication with RS-232C using BASIC language. Digital logic parts design ADS driving signals with Xilinx FPGA and are simulated by ModelSim 5.5f. Power circuits convert output of digital logic parts into high voltage which panel is drived.

기존 PDP 전원 시스템은 일반적으로 두 개의 절연형 트랜스포머를 사용하여 서스테인 전원($V_S$)과 어드레스 전원($V_A$), Multi단 전원($V_M$)으로 구성된다. 이들 각 전력 변환 회로에 트랜스포머 및 제어 IC가 사용되므로, 효율 저감 및 원가 상승, 소자 스트레스 등의 단점을 가지고 있다. 본 논문에서는 절연형 트랜스포머 한 개로 PDP 전원시스템을 구동하는 방식에 대해 제안한다. 제안된 방식은 DC/DC 전력단의 고효율 동작 및 신뢰성 개선은 물론 부피, 크기를 줄여 원가 저감에 기여한다. 또한, 제안된 방식은 PDP 구동 방식의 하나인 Address Display-period Separation(ADS)에 적합하다. 기존 방식과 제안된 방식을 비교하고 이론적 분석과 실험을 통해 제안된 방식의 우수성을 확인하였다.

A new sustainer with primary-side integration of DC/DC converters and energy recovery(SPIDER) circuits is proposed. The proposed circuit operates as a DC-DC converter during address period and energy recovery circuit during sustain period. Therefore, the conventional three electronic circuits composed of the power supply, X-driver, and Y-driver can be reduced to one circuit. As a result, it has desirable advantages such as a simple structure, less mass, fewer devices and cost reduction. Moreover, since the Zero Voltage Switching (ZVS) of all power switches can be guaranteed, a switching loss can be considerably decreased. To confirm the operation, validity, and features of the proposed circuit, experimental results from a prototype for 42-inch PDP are presented.

본 논문에서는 최근 3D 콘텐츠의 증가로 다시 주목을 받고 있는 PDP TV를 위한 저가형 구동 시스템을 제안한다. PDP TV의 경우 기체 방전을 이용하여 영상을 표시하는 장치로서 진공 상태의 패널에 수많은 전압을 가하여 플라즈마 상태로 만든 다음 영상 신호에 의하여 영상 및 밝기가 표현된다. 이러한 PDP TV는 많은 전압을 가하기 위하여 3개 전극에 각각 필요한 구동회로 보드가 붙게 되는데, 대 전력을 다루기 때문에 보드 사이즈와 사용되는 소자가 큰 가격을 차지하고 있다. 본 논문에서는 기존의 3개의 보드로 이루어진 구동 시스템을 오방전을 보상하기 위한 어드레스 에너지 회수 구동회로를 포함한 2개 보드로 이루어진 새로운 저가형 PDP TV 구동회로를 제안하고 이를 42인치 HD PDP TV를 통해 검증한다.

The spatio-temporal variation of Infra Red(IR) emission images were obtained from a real 3-dimensional discharge space of a surface discharge type, alternating current plasma display panel(AC PDP) cell with the Ne-Xe(4%) 400Torr gas mixture. IR emissions were observed in each period of the ADS(Address and Display Separation) driving scheme with ramp initializing waveform using an images intensified charge coupled device(ICCD) camera. The roles of each electrode were identified and it was compared with the results of the discharge simulation and of the wall charge distributions measured by the electro-optic technique.
