摘要：
A current detection data is acquired by a scanning line current detection resistance, an adder-subtracter and an A/D converter. the current detection data is inputted to a voltage correction circuit, the voltage correction circuit output a correction signal. Using the correction signal, a scanning electrode voltage correction circuit performs the correction of the scanning selection voltage. Further, the voltage correction circuit generates data electrode drive data based on the current detection data and image data and inputs the data electrode drive data to a data electrode drive circuit. the present invention prevent a change of brightness and of smear with time.
