Drive current regulator circuit, organic EL element drive circuit using the same drive current regulator circuit and organic EL display device using the same organic EL element drive circuit

摘要

A drive current of every terminal pin is regulated according to data stored in a rewritable non-volatile memory by ON/OFF switching the data by a switch circuit. By writing data necessary for luminance regulation for correcting luminance variation or luminance unevenness in the non-volatile memory, luminance variation or luminance unevenness is reduced.
