Abstract: | Abstract— By applying an energy‐recovery method to their driver circuits, the circuit power consumption of plasma displays can be reduced. However, further power reduction is necessary for large‐sized higher‐resolution displays such as used for Super HDTV. The ideal adiabatic charge method has been proven to be able to minimize circuit resistive element power consumption to 81 % of the conventional energy‐recovery‐circuit resistive‐element loss. An experimental pseudo‐adiabatic charge circuit that reduces the power consumption to about 90% of a conventional circuit has been demonstrated. The power consumption caused by both the resistance loss and the discharge loss of the switching‐element parasitic capacitances was analyzed. |
