Abstract
A digital-to-analog converter and a driving circuit of a display device including such converter are discussed. The digital-to-analog converter can include a decoder configured to select one of a plurality of gamma voltages corresponding to a grayscale value of image data and output the selected gamma voltage to an output terminal, and a slew rate controller connected to the output terminal of the decoder. The slew rate controller includes a pull-up transistor connected between a high-potential voltage and the output terminal, with a gate electrode configured to receive a first slew rate control signal, and a pull-down transistor connected between a low-potential voltage and the output terminal, with a gate electrode configured to receive a second slew rate control signal.
