Abstract
A drive unit for driving a corresponding one of organic EL elements of an active matrix EL display device includes a blanking switch for blanking the video signal stored in a storage capacitor in each frame period before the start of the next frame period. A drive transistor drives a corresponding EL element based on the correct current supplied for this If the video signal is a current signal, a transistor operating as a current-voltage converter is provided
