  • Patent number: 8009129
    Abstract: During a blanking period of a video signal, an element driving transistor for controlling a drive current supplied to an EL element is operated in its saturation region to thereby set the EL element to an emission level, and a current flowing through the EL element at that time is detected. Each current detector includes a current detection amplifier and a successive approximation type AD converter, and a DA converter of the successive approximation type AD converter is commonly shared among a plurality of the AD converters. With this arrangement, sufficient AD converting speed can be attained while using a simple structure to execute current detection for correcting display variations.
