  • Patent number: 11417278
    Abstract: Disclosed are a display device and a driving method thereof. A reference compensation voltage for compensating for a node voltage of each pixel for an image holding period after a refresh period for which image data is input in a low-speed driving mode is set. Then, the node voltage of each sub-pixel is compensated for using a corresponding reference compensation voltage on at least one frame basis at each start time and each end time of the image holding period, thereby preventing low image quality and reducing power consumption.
    Type: Grant

  • Patent number: 11417283
    Abstract: Disclosed herein are a display device for low-speed driving and a driving method thereof. The display device according to embodiments of the present disclosure may set a reference compensation voltage for compensating a node voltage of each pixel during an image holding period after a refresh period where image data are input at the time of low-speed driving, and may compensate a node voltage of each sub pixel on the basis of a unit of at least one frame during each image holding period between the refresh periods, thereby making it possible to prevent a deterioration of image quality and reduce electricity consumption.
