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

A new current-fed energy-recovery circuit for a plasma display panel is proposed. All power switches are turned on with zero-voltage-switching, and its sustaining voltage is greatly reduced with the aid of the discharge current compensation. Furthermore, it features a simpler structure, less mass, lower current stress, and lower electromagnetic interface than prior circuits. It is well suited for wall-hanging colour TVs. 相似文献

A new sustainer circuit with multilevel voltage wave-shaping characteristics for an AC plasma display panel (AC-PDP) drive is proposed. The proposed circuit features half the device voltage stresses and significantly reduced power losses compared with those of the conventional ones. This circuit, realizable without much increased cost of the semiconductor devices, gives a significant improvement in the power efficiency, essential for the design of a drive circuit for the AC-PDP. A comparative analysis and experimental results are presented to show the validity of the proposed sustainer circuit. 相似文献

A new sustaining driver for a plasma display panel (PDP) employing a gas-discharge current compensation method is proposed. It features a high performance, zero-voltage-switching, high efficiency, low EMI and high energy-recovery capability. Furthermore, since it compensates for the large gas-discharge current, it enables the PDP to light at a lower voltage than the prior circuit. 相似文献

A new zero-voltage and zero-current switching (ZVZCS) energy-recovery circuit (ERC) for a plasma display panel (PDP) is proposed. The external current source ensures the zero-voltage turn-on of all MOSFETs, zero-current turn-off of all IGBTs, and fully charged/discharged PDP, which desirably reduce the sustaining voltage. Moreover, it features simpler structure, fewer devices, lower cost, lower electromagnetic interference noise, and lower current stress. 相似文献

A cost-effective plasma display panel (PDP) sustainer employing current injection method (CIM) for energy recovery is proposed. Using a voltage-balancing technique, driver cost can be reduced by about 20%-30% compared with that of the conventional H-bridge driver by using low-voltage switches. The energy recovery performance can be improved by the current that is built up before the energy recovery operation. This buildup current is utilized to change the polarity of the panel electrode and provides additional variable to determine pulse slopes. Experimental results show that the voltage stress of switches connected in series is identically clamped to sustain voltage during sustain operation and that light is emitted more stably by independent control of the rising and falling slopes using CIM. Therefore, the proposed sustainer is expected to be suitable for a low-cost PDP sustaining driver requiring stable discharge characteristics. 相似文献

A new ac plasma display technique is described in which the alternating sustain function is achieved on the back or substrate glass surface and thex-y selected write-addressing uses a transparent front cover electrode and a substrate electrode. The three-electrode-per-pel structure achieves high overall emission efficiency as a result of nonshielded sustain discharges and low electrode capacitances. 相似文献

A resonant energy-recovery circuit for a plasma display panel (PDP) employing a gas-discharge current compensation method is proposed. Its main concept is to make the resonant circuit biased by V/sub s/ and 0V instead of V/sub s//2 in charging and discharging the PDP, respectively. This operation helps the PDP to be fully charged and discharged and all main switches turned on under zero-voltage switching. Moreover, since the inductor current can compensate the large gas-discharge current, the current stresses on main power switches can be considerably reduced and all main switches have the turn-on timing margin, which ensures the no voltage drop across the PDP. Therefore, all these features could favorably provide a high energy-recovery capability, more accumulated wall charge, reduced sustaining voltage, and low electromagnetic interference. Therefore, the proposed circuit is expected to be well suited for a hang-on-the-wall PDP TV. 相似文献

A regenerative power electronic circuit is proposed to drive a plasma display panel (PDP) in sustain-mode operation. This driver utilizes inductors to resonate with the equivalent intrinsic capacitance of the PDP to avoid the abrupt charging/discharging operation. The energy losses due to conventional hardswitching driving and the displacement current of the PDP are mainly recovered. Compared with prior approaches, this driving circuit has a quite simple structure and is suitable for asymmetrical operation 相似文献

A minicomputer-controlled system is used to automatically measure the wall charge transfer curve of a single cell in an ac plasma display panel. Curves can be plotted on a graphics display as fast as 5/s which allows real-time interaction with the user. The measurement technique is based on the ability to directly measure the wall charge from a single cell. The minicomputer controls the sustain voltage across the cell and obtains the resulting wall charge. It then does the tedious algebra needed to complete the transfer curve. The measured curves show numerous interesting effects. The influence of the state of the neighboring cells can clearly be seen. The duty factor of the sustain waveform has a strong influence on the transfer curve. An effect dependent on sustain frequency is presented that shows a transfer curve region with negative slope. The most interesting effect measured is a hysteresis in the transfer curve, in that a different curve is traced out as the cell goes from off to on than when it goes from on to off. 相似文献

Using an electron transport mechanism, a self-shift display has been successfully implemented on an ac plasma panel providing higher resolution, higher shifting speed, and wider operating margins than previously obtained. The mechanism consists of a unidirectional and efficient transport of a large portion of electrons (generated during the display site discharge) to a neighboring OFF transfer site by a low transverse voltage. The process results in a large wall voltage build-up at the transfer site to switch its state from OFF to ON. The implemented electron transport self-shift display consists of a 7 × 128 site array of an Owens-Illinois 60 lines per inch panel where the 128 columns are driven by a four-phase driver. A resolution of one display site for every two electrodes and a shifting speed better than 600 characters per second have been successfully demonstrated. The ranges of the shifting voltages VD and VT are better than 15 V over a 10-V sustain range. The shifting operation also was successfully demonstrated on an 83 lines per inch panel with good operating margins. 相似文献

The basic characteristics of reset discharges related to a wall voltage and a priming effect were investigated under a conventional ramp driving scheme. The reset discharges could be minimized by controlling the wall voltage which is determined by pre-reset conditions. Accordingly, the current study presents a simple pre-reset condition for minimizing the reset discharge. Essentially, it is not only to reduce the duration of reset discharges but also to reduce the intensity of light emissions when the wall voltage polarity is opposite to the external voltage polarity. 相似文献

The regularity of the pulsed discharges in the plasma display panel is attributed to processes which automatically damp out perturbations from equilibrium conditions. With rectangular wave excitation, these processes are controlled by the dependence of wall voltage changes during a discharge on the cell voltage at the beginning of a discharge. Conditions for stability and instability are derived for both simple series, in which all discharges are identical, and for more complex series of recurrent discharge sequences, for which the discharges within a sequence need not be identical. 相似文献

A two-dimensional computer simulation for the surface-discharge ac plasma display panel shows that the suppression electrodes perform the function of confining the discharge area within a unit cell. This is due to the effect of the suppression on the surface potential caused by the ion or electron accumulation on the dielectric protecting layer rather than the pinch effect on the electric field. The investigation of the effects of various panel dimensions on the discharge pattern resulted in discovery of an analytical relationship that can be used to determine whether the discharge pattern is a criss-cross or single-sided one for given panel dimensions. The formation mechanism of the crisscross discharge pattern was clarified from the consideration of the computer simulation and the computer-aided image processing of the discharge pattern from an experimental surface-discharge ac plasma display panel. 相似文献

A new concept of energy recovery for a plasma display panel (PDP) is proposed. Different from conventional LC resonant sustaining drivers, the current built up before inverting the polarity of the panel electrodes is utilized to change the panel polarity together with energy previously charged in panel capacitance. This operation provides zero-voltage switching of switches and reduction of electromagnetic interference by rejecting the surge current when the sustain switches are turned on. The buildup current helps to reduce the transition time of the panel polarity and may produce more stable light waveforms. This method is suitable for a PDP sustaining driver requiring stable light emission characteristic while it maintains low circuit loss like the series-resonant-type energy recovery circuit which is known to be a very effective method. 相似文献

Surface-discharge-type plasma display panel 总被引:1,自引:0,他引:1

The surface-discharge type plasma display panel does not require accurate spacing between two plates. Also, the number of manufacturing processes can be reduced to nearly half those required for opposed-discharge-type panels, resulting in low cost. The relationship between the principal design factors of a surface-discharge-type panel and the firing voltage in the nonmemory mode is discussed, based upon experiments and calculations from an equivalent circuit. Furthermore, by making use of the fact that one side of the panel is simply a cover glass for the gas space, it is possible to obtain green emission by coating a phosphor on the inside surface of the cover glass. In this arrangement, degradation of the phosphor by ion bombardment seldom occurs and long life panels can be achieved. 相似文献
