  • Patent number: 12755711
    Abstract: A display device senses a driving current of each of pixels to determine a temperature of a display panel, and performs a stain compensation based on the temperature of the display panel. The display device determines whether the display panel has transitioned from a first deterioration state to a second deterioration state and an average grayscale of input image data is less than a grayscale threshold value, such that the display device reduces a sensing period of the sensing current.

  • Patent number: 11763771
    Abstract: A liquid crystal display device includes a source device that outputs image data and a sink device that performs a displaying operation based on the image data. The source device changes a frame rate of an image frame composing the image data while the displaying operation is performed. The sink device changes a frame rate of a panel driving frame for the displaying operation by adjusting a vertical blank period of the panel driving frame as the frame rate of the image frame is changed. Here, the sink device adjusts a common voltage applied to a display panel included in the sink device during a display operation of an individual frame, in accordance with the frame rate of the panel driving frame.
