Abstract
A picture-based high-speed address recovery technique for AC (adaptive control) plasma display panels (PDPs) is proposed. By removing the ground (GND) switching operation, the recovery speed can be increased and the switching loss due to the GND switch is reduced. The proposed method can perform load-adaptive operations by controlling the voltage level of the energy recovery capacitor, which prevents the increase of inefficient power consumption caused by circuit loss during the recovery operation. Thus, the technique shows the minimum address power consumption according to various displayed images, which is different from previous methods operating in fixed mode regardless of images. Test results with a 50-in HD single-scan PDP (resolution=1366 times 768) show that a recovery time of less than 350 ns is successfully accomplished and about 54% of the maximum power consumption can be reduced, by tracing the minimum power consumption curves.
