Abstract: A luminance adjustment part includes a luminance determination part and a data compensation part. The luminance determination part may determine a control value for controlling luminance of a backlight assembly using linear image data that has a linear luminance profile and is generated by performing a de-gamma process on a first copy of input image data that has a nonlinear luminance profile. The compensation part may compensate pixel data that corresponds to pixels of a display panel using the control value, the pixel data being generated using a second copy of the input image data. Thus, color distortion of a displayed image as perceived by a viewer may be minimized when power consumption of a display apparatus that includes the display panel is decreased.

Abstract: In a display device, each of pixels includes a light emitting element and a pixel circuit which is connected to the light emitting element at a first node and drives the light emitting element in response to a corresponding driving scan signal among driving scan signals during a display period. The pixel circuit is connected to a corresponding readout line among readout lines at a second node. The sensing circuit senses a potential of the first node through the corresponding readout line during a blank period, and each of frames includes the display period and the blank period. At least two driving scan signals among the driving scan signals respectively include a plurality of rewriting periods, each of which is activated during the blank period corresponding thereto, and the rewriting periods of the driving scan signals have different durations from each other.

Abstract: A method of driving a display device includes a writing operation and a reading operation. The writing operation includes writing first to Mth frame data in a first frame memory during first to Mth frame periods. The reading operation includes reading (L−M)th and (L−M+1)th frame data among the first to Mth frame data from the first frame memory during an Lth frame period. M may be three or more, and L may be an integer ranging from (M+1) to (2M−1). The frame data read from the first frame memory corresponds to an image to be displayed. Reading and writing operations are further performed for remaining ones of the frame memories.
