Abstract: A flexible display device including a flexible display panel, and a panel driver configured to receive display data from a host processor, to store the display data, and to drive the flexible display panel based on the display data. While the flexible display panel is deformed, the panel driver drives the flexible display panel based on the display data stored before the flexible display panel is deformed to display an image having a size suitable for a current exposed region of the flexible display panel.

Abstract: A display apparatus includes a display panel, an afterimage compensator and a data driver. The display panel displays an image. The afterimage compensator writes first stress data of input image data corresponding to a first area to a first memory area in a first block size and second stress data of the input image data corresponding to a second area to a second memory area in a second block size different from the first block size and compensates a grayscale value of the input image data based on the first stress data and the second stress data. The data driver generates a data voltage based on a compensated grayscale value and outputs the data voltage to the display panel.

Abstract: A display panel driver includes: a driving controller receiving input image data and converting the input image data into a data signal and a data driver converting the data signal into a data voltage. The driving controller includes a plurality of lookup tables storing data signal values corresponding to grayscale values of the input image data based on an input maximum luminance, and a total number of the data signal values stored in a first lookup table corresponding to a first input maximum luminance is different from a total number of the data signal values stored in a second lookup table corresponding to a second input maximum luminance.

Abstract: A display device includes a display panel, an input sensor disposed on the display panel, a panel driving circuit which drives the display panel and generates a first driving voltage, and a readout circuit which controls the input sensor. The readout circuit receives the first driving voltage from the panel driving circuit and outputs transmit signals to control the input sensor.
