Reducing the Power Consumption in the EL Displays

摘要：

In the Electroluminescent display panels, the largest portion of power consumption of data driver circuits conies from charging and discharging quite large capacitive loads, data lines. The proposed multi-steps data driving method can reduce the panel AC power consumption into only a few percent of that of conventional ones if the number of steps is large enough. In the proposed driving method, external capacitors supply charge to loads in multi-steps manner, and the charge returns to the capacitors instead of being discharged to ground. This charge recycling is the basis of reduction of the panel AC power. In this paper, the author gives a hardware implementation of 4-steps voltage generator with a minimum complexity.
