Abstract
An example display driving device includes a level shifter and a digital-analog converter (DAC). The level shifter is configured to receive image data and a bias control signal, to generate decoded image data including a plurality of bits by level shifting the image data, and to control an output bias current of the decoded image data based on the bias control signal. The DAC is configured to receive the decoded image data and a plurality of gamma voltages, to select one gamma voltage of the plurality of gamma voltages based on the decoded image data, and to output the selected gamma voltage.
