    Abstract: Disclosed is an organic light emitting display device and a method of driving the same that can improve compensation performance of degradation of a driving TFT. A method of driving an organic light emitting display device comprises generating an estimated degradation value of a driving TFT by using accumulated data through input data counting; compensating all the pixels of a display panel by using a first gain value, which is initially set, and the estimated degradation value; generating a sensing value by sensing all or some of the pixels of the display panel after driving is performed for a certain time; generating a second gain value by compensating the first gain value if an error between the estimated degradation value and the sensing value is more than a reference value; generating compensation data by compensating the estimated degradation value by using the second gain value; and compensating all the pixels of the display panel by using the compensation data.

    Abstract: A flicker reduction device of a display apparatus can include a frame memory configured to store image data of an input frame synchronized with an input frame frequency, a first circuit configured to output a first control signal when a plurality of fixed active periods based on a reference frame frequency are allocated within each input frame time corresponding to the input frame frequency and output a second control signal when only one fixed active period is allocated within each input frame time, and a second circuit configured to copy the image data of the input frame according to the first control signal and output image data of a plurality of input frames according to the reference frame frequency. The second circuit outputs the image data of the input frame according to the reference frame frequency without copying according to the second control signal.
