Abstract: A display driving circuit includes a first bias circuit, a second bias circuit, a selector, and an output buffer. The first bias circuit generates a first bias voltage set. The second bias circuit generates a second bias voltage set. The selector selects one of the first and second bias voltage sets based on a bias selection signal. The output buffer buffers a grayscale voltage corresponding to display data and outputs the buffered grayscale voltage The output buffer is biased based on the first or second bias voltage set selected by the selector.
