    Abstract: A disclosed display device includes a data driver configured to receive data signals corresponding to an input image and to output a first data signal corresponding to a first portion of the input image to be displayed. The display device also includes a display panel having a plurality of data lines and a display area configured to display the first portion of the input image based on the first data signal from the data driver. The data driver is further configured to cut off a second data signal corresponding to a second portion of the input image substantially outside the display area of the display panel from being output.
