Abstract

A silicon based OELD driving circuit that has a new type of column driving method is proposed to reduce the driving circuit area. In comparison with the conventional method, latches in each column are removed and one DAC (digital-to-analog converter) drives several column lines. To make the DAC operate during a specific period for the low power consumption, a simple DESG (DAC Enable Signal Generator) circuit was devised and confirmed by the simulation.
