Abstract
A data driving circuit is disclosed that includes an amplifier and an offset control circuit. The amplifier has an offset voltage and is configured to output a data voltage reflecting the offset voltage. The offset control circuit is configured to control, in response to an input control signal, the amplifier to output the data voltage reflecting the offset voltage in a positive direction or a negative direction. The data driving circuit may enhance the display quality of a low grayscale image.
