ABSTRACT:
Aspects of the invention can provide a digital-to-analog converting circuit 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.
