Abstract
Provided is a source driver circuit for an active matrix electroluminescent (EL) display including a digital-to-analog converter/ramp circuit for converting a digital signal into an analog signal, and generating a ramp signal in this process, simultaneously, whereby high degree of integration would be possible since a conventional complicated circuit is not required and gray scale with the high characteristic can be implanted, regardless of a change of a temperature or a threshold voltage.
