Abstract: A display apparatus includes a display panel including a plurality of pixels; a timing controller generating image data, a data control signal, and a gate control signal, based on an input image signal and an input control signal; a data driver generating a data signal for an output image based on the image data and the data control signal and supplying the data signal to the pixels; a gate driver generating a gate signal based on the gate control signal and supplying the gate signal for the output image to the pixels. The timing controller detects a frame period corresponding to a frame rate of the input image and when the detected frame period is longer than the critical period, inserts a sub frame duration to output active data for image refresh after outputting active data of an output frame duration corresponding to the output image.
