    Abstract: A display device includes a display panel which displays an image, where a plurality of areas, in each of which a plurality of pixels is positioned, is defined in the display panel, and a controller which generates image data based on an image signal received from the outside and compensates for deterioration of the display panel. The controller includes a stress information generator which generates stress information of the display panel corresponding to the deterioration and a deterioration compensator which changes at least one selected from a spatial resolution and a bit-depth of each of the plurality of areas based on the stress information of each of the plurality of areas.

    IPC: G09G3/00

    Abstract: A display apparatus includes a display panel, a driving controller and a data driver. The driving controller is configured to predict a panel temperature according to a position in the display panel based on input image data, to calculate a block current of a display block of the display panel and a panel resistance according to the position in the display panel based on the panel temperature, to calculate a voltage drop according to the position in the display panel based on the block current and the panel resistance and to compensate the input image data based on the voltage drop to generate a data signal. The data driver is configured to convert the data signal to a data voltage and to output the data voltage to the display panel.

    Abstract: A foldable display device is disclosed that includes a flexible display panel, an optical module, and a deterioration compensator. The flexible display panel includes a folding line, a first display area disposed on a first side of the folding line, and a second display area disposed on a second side of the folding line to display a test image. The optical module is disposed in the first display area and is configured to sense a display luminance of the test image. The deterioration compensator is configured to perform a deterioration compensating operation of the display luminance by a luminance compensation value when the display luminance is less than a target luminance, without performing the deterioration compensating operation when the display luminance is greater than the target luminance.
