Driving device and driving method of organic thin film EL display

摘要

A comparator (compares the signal voltage S (i, j) applied to the display element P(i, j) on a predetermined data electrode (Xi) on the scanning electrode (Yj) for the current display period and the signal voltage S(i, j+1) applied to the display element P(i, j+1) on the data electrode (Xi) on the scanning electrode Y (j+1) during the next display period. A controller controls a discharge of residual electric charges or a quantity of residual electric charges discharged from the data electrode (Xi) during a blanking period immediately before the next display period depending on the comparison result by the comparator.
