摘要： A display device and a driving method thereof are disclosed. In one aspect, the display device includes: a memory which receives an input image data at a first frame frequency and a frame rate controlling unit which converts the input image data to an output image data output at a second frame frequency higher than the first frame frequency by duplicating the input image data to a plurality of frames. The display device also includes a release frame inserting unit which periodically designates release frames in the output image data for resolving a DC bias of one or more continuous frames and a data compensating unit which compensates for a value of the output image data or determines the value of the output image data.
