PDP 列驱动芯片能量恢复效率模型
Models for energy recovery efficiency of PDP data driver IC
摘要
Abstract
Two analytical models are proposed to analyze the energy recovery efficiency of PDP data driver IC.DPLD (double-channel p-type lateral extended drain MOS)transistor is the key device of energy recovery circuit of data driver IC.CRC (Capacitor Resistor and Capacitor)equivalent circuit model is suitable for DPLD transistor which has poor drain current capacity.VCCS (Voltage Con-trolled Current Source)model is suitable for DPLD transistor which has strong drain current capacity. The test results reveal that both CRC and VCCS models have high precision,the model errors are 2.26% and 4.04%.CRC model reveals that the energy recovery efficiency of data driver IC is influ-enced by three factors,which are the charge time,channel resistor and load capacitor.The compared results of two models show that channel resistor has great influence on energy recovery efficiency of data driver IC.The energy recovery efficiency of PDP data driver IC can be improved significantly by using DPLD transistor which has smaller channel resistor.The proposed CRC and VCCS models can be used to predict the energy recovery efficiency accurately.关键词
