Abstract

This paper analyzes and compares the penal power consumption for mobile TFT-LCDs. Three representative penal driving schemes (the basic data driving, the charge-recycling data driving, and the stepwise data driving) based on the line inversion driving method are considered in this analysis, and equations for representing the penal power consumption of respective driving schemes are derived. This is the first to analyze the panel power consumption of line inversion-based mobile TFT-LCDs including parasitic capacitance effect. The analysis procedure presented here is helpful for power study, and gives benefits of providing accurate estimation of the total power consumption of mobile TFT-LCDs driven a line inversion driving.
