摘要： A current programming apparatus having two data lines for a pixel line is presented. An image data current is supplied to the first and the second data lines alternatively by switching M1 and M2 complementally. By switching M7 and M8 on during the switches M1 and M2 turn on respectively, a constant current is supplied to the data line to which the data current is not supplied. The scanning signals are applied so as to write a constant current into pixels immediately before the data current is written. Thus a write-in defect by a fluctuation in the threshold voltages is prevented.
