ABSTRACT:
A digital-to-analog converting circuit is provided that is capable of, after converting digital data into an analog current, correcting the current value based on digital current correction data without any complex processing. The exemplary digital-to-analog converting circuit can include a first digital-to-analog converting circuit portion and a second digital-to-analog converting circuit portion. First digital data (image data) can input to the first digital-to-analog converting circuit portion, and second digital data (current correction data) can input to the second digital-to-analog converting circuit portion. After the first digital-to-analog converting circuit portion converts the image data into a first analog current, the second digital-to-analog converting circuit portion can correct the first analog current based on the current correction data, and outputs the corrected current as a second analog current.
