Cost-Effective Charge Sharing Address Driver with Load Adaptive Characteristic

摘要

A cost-effective charge sharing address driver for plasma display panel (PDP) is proposed. The proposed address driver utilizes an auxiliary circuit to reduce the voltage across the data driver IC when its output stages change their status. The auxiliary circuit absorbs some of the energy stored in the panel and provides the energy absorbed to the panel. Therefore, it can reduce the power consumption and relieve the thermal problems of the driver ICs. Moreover, it has load adaptive characteristics (LAC). Compared to LC resonant driving method, the component count is significantly reduced and the light load efficiency is improved due to LAC.
