Abstract
Discussed are a display device and a method for controlling the same, which are capable of achieving a reduction in power consumption, through selective application of a charge share mode or a pre-charge mode in accordance with the swing width of a data voltage. The disclosed method includes the steps of determining a positive or negative polarity of input image data on the basis of reference data and outputting a pre-charge enable signal when two successive image data have the same polarity; supplying a pre-charge voltage to a corresponding output channel in response to the pre-enable signal; and converting the image data into a data voltage, supplying the converted data voltage to a corresponding data line through the corresponding output channel.
