    Abstract: A driving controller includes a compensation unit that receives an image signal corresponding to a first display area and a second display area, calculates stress data based on the image signal and previous stress data, and outputs an image data signal, which is obtained by compensating for the image signal based on the stress data, a memory that stores the stress data of a previous frame from the compensation unit and provides the previous stress data, and a multi-frequency compensation unit that receives a data enable signal, counts a number of consecutive masking enable frames when the data enable signal indicates a multi-frequency mode, calculates accumulated second stress data based on the number of the consecutive masking enable frames and second stress data, which corresponds to the second display area, from among the stress data from the memory, and stores the accumulated second stress data in the memory.

    Abstract: A display device includes a display panel, a gate driver, and a driving controller. The display panel includes a pixel. The gate driver applies an anode initialization signal to the pixel. The driving controller receives a horizontal synchronization signal, receives input image data at a variable frame frequency, and controls the gate driver. A frame period for the display panel includes a scan period and one or more hold periods, the driving controller generates a count value by counting a number of pulses of the horizontal synchronization signal, and determines a current frame period as the hold period when the count value exceeds a reference value, and a time length of the anode initialization signal in each of the one or more hold periods is longer than a time length of the anode initialization signal in the scan period.

    Abstract: A display device comprises a display panel including a pixel, and a panel driver configured to receive input image data in a variable frame frequency in order to drive the display panel based on the input image data. A frame period for the display panel is divided into at least one scan period and at least one or more hold periods, and a time during which the pixel performs an anode initialization operation in each of the hold periods is longer than a time during which the pixel performs the anode initialization operation in the scan period.
