1引言等离子体显示按照电极结构分为直流型(DC-PDP)和交流型(AC-PDP)。目前大多数厂家都采用三电极表面放电AC-PDP,即采用A,X和Y三电极,在工作时电极之间施加交替脉冲信号,从而使放电单元的气体发生气体放电产生紫外线,激发荧光粉发光。PDP早在1964年就由美国Illinois大学的Bitzer和Slottow发明出来,但是直到20世纪90年代才获得迅速发展,这不仅应当归功于显示屏本身开发成功及生产技术的进步,也应当归功于驱动技术的发展,而驱动技术的发展又有赖于驱动集成电路的发展。2PDP驱动原理三电极表面放电型A… 相似文献

This paper presents a cost-effective sustain power conversion scheme for the plasma display panel (PDP). A new energy-recovery (ER) circuit is proposed for a low-cost sustain driver. As a parallel-resonant type ER circuit, it can recover the energy stored in the PDP without the interconnection of the sustaining and scanning electrodes. It has a simple structure and fewer power devices, providing a lower cost of production. In addition, a high efficiency sustain power supply is proposed to provide a constant sustain voltage for the sustain driver. It achieves zero-current turn-off of the output diode, alleviating the diode reverse-recovery problems. The sustain power efficiency is increased by reducing the switching power loss. Therefore, the cost and power consumption of the PDP can be improved. The proposed circuits are theoretically analyzed in detail. The experimental results based on a 32-in PDP are presented to confirm the validity of the proposed circuits. 相似文献

A novel driver with discharge current compensation is proposed to drive an AC plasma display panel (PDP). This proposed circuit uses resonance between the inductor and the AC PDP to avoid abrupt charging/discharging. The four switches of the full bridge are all operated with zero-voltage-switching turn-on. In addition, an 8-in AC PDP equipped with the proposed driving circuit, operating at 100 kHz, is investigated. With the discharge current compensation, the experimental results show that the proposed driver can maintain the AC PDP to light at lower voltage (129 V) 相似文献

A novel energy-recovery driver is proposed to drive a plasma display panel (PDP) in the sustaining operation. The proposed circuit uses the parallel resonance between the inductor and the intrinsic capacitance of PDP to mainly recover the energy lost by the capacitive displacement current of the PDP. The parasitic resonance caused by the parasitic inductance and the stray capacitance is prevented greatly. A 34-in AC PDP equipped with the proposed driving circuit, operated at 100 kHz, is investigated. In addition, some prior work is shown in this paper for comparison, in which the power consumption of driving the same 34-in panel is measured. The experimental results show that the proposed driver has a low-cost structure and better performance than the prior ones. 相似文献

A new energy-recovery sustaining driver for an AC plasma display panel (PDP) is proposed. Since it has only one auxiliary switch compared with the four of the prior circuit, its size and cost can be greatly reduced. Moreover, it features the fast transition time of the panel polarity, fully charged and discharged PDP and soft switching of all power switches. 相似文献
