Abstract
A display device includes display device includes: a display panel including a plurality of pixels; a data driver configured to generate data voltages based on output image data, and to provide the data voltages to the plurality of pixels; and a controller configured to receive input image data and input frequency information from a host processor, and to provide the output image data to the data driver, wherein the controller includes an adaptive refresh block configured to: determine a target frequency by analyzing the input image data; determine a masking ratio based on an input frequency represented by the input frequency information and the target frequency; and selectively output the input image data as the output image data by performing a masking operation on the input image data with the masking ratio.
