The sustain waveforms are distorted relative to the displayed area. The distorted sustain waveform, especially the last X sustain waveform causes the address time to be delayed. Accordingly, to produce a stable address discharge irrespective of the displayed area, the sustain waveform, especially the last X sustain waveform prior to the selective reset waveform, is compensated by making its rising slope faster in proportion to the displayed area by means of controlling the timing sequence of the energy recovery circuit (ERC) circuit. As a result, the compensated sustain waveform enables the address delayed time to be saturated irrespective of the displayed area.

High Efficiency Alternating Current Driver for Capacitive Loads Using a Current-Balance Transformer

This paper proposes a new alternating current driving method for highly capacitive loads such as plasma display panels or piezoelectric actuators, etc. In the proposed scheme, a current balance transformer, which has two windings with the same turnratio, provides not only a resonance inductance for energy recovery but also a current balance among all of the switching devices of the driver for current stress reduction. The smaller conduction loss than conventional circuits occurs due to the dual conduction paths which are parallel each other in the current balance transformer. Also, the leakage inductances of the transformer are utilized as resonant inductors for energy recovery by the series resonance to the capacitive load. Furthermore, the resonance contributes to the small switching losses of the switching devices by soft-switching operation. To confirm the validity of the proposed circuit, prototype hardware with a 12-inch mercury-free flat fluorescent lamp is implemented. The experimental results are compared with a conventional energy-recovery circuit from the perspective of luminance performances.

“…With 1/2 V s of resonant energy, the panel voltage then changed to V s from its initial level, thereby explaining the description of Weber's ERC as a 3-level-type ERC (-Vs -zero --+Vs). Weber's ERC also facilitates many topology variations, plus the driving sequence can be easily and independently changed for each driving board (X and Y) [5]. Fig.…”

The iterant strong sustain discharge during a sustain period was known to induce an image sticking problem, but its detailed mechanism is not still fully understood. It is found that the rising slope of the sustain waveform has a significant influence on the recovery time of temporal bright image sticking. As a result, the recovery time of temporal bright image sticking is shortened considerably by properly controlling the rising slope of the sustain waveform.
