ABSTRACT:
When display data for both odd-numbered and even-numbered scan electrodes in an electroluminescent display are both actuating data, the brightness of electroluminescent elements connected to the odd-numbered electrode is adjusted by adjusting the timing for starting the application of the actuating voltage and the brightness of electroluminescent elements connected to the even-numbered electrode is adjusted by adjusting the timing for terminating the application of the actuating voltage. Moreover, electric charge in the EL elements is retained by maintaining the application of the actuating voltages during scanning operations.
