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.

Abstract: A display device includes a display panel including a plurality of pixels, a power supply transmitting driving power to the pixels via a power line and stopping transmission of the driving power in response to a crack signal, a panel driver provides a driving signal to the pixels, the driving signal for displaying a black image during a non-emission period of each frame period and displaying a valid image during an emission period of each frame period, and a crack detector senses a current flowing through the power line and conditionally generate the crack signal according to values of the current sensed over M successive frame periods, where M is an integer greater than 1.
