  • Publication number: 20240257706
    Abstract: Embodiments relate to a display device and driving method thereof. A display device includes a display panel including a sub-pixel, a data driver including a driving circuitry configured to output data voltage to the sub-pixel and a sensing circuitry configured to sense a characteristic of the sub-pixel, and a timing controller configured to determine a compensation value of video data based on the sensed characteristic and corrects the compensation value based on sensing of an output data voltage of the driving circuitry.

  • Publication number: 20240257680
    Abstract: Aspects relate to a display device and driving method thereof. A display device includes a display panel including a sub-pixel and displaying an image in units of frames, a data driver including a driving circuitry applying data voltage to the sub-pixel during an active time displaying an image within one frame and a sensing circuitry sensing the sub-pixel during the active time, and a timing controller detecting a defect of the display panel based on a sensing result of the sensing circuitry, wherein the frame includes an active time for display the image and a blank time for sensing a characteristic value of the sub-pixel, and the timing controller turns on the sampling switch at least one time during the active time.

  • Publication number: 20240212571
    Abstract: Disclosed is a display apparatus comprising a display panel including data lines connected to a driving transistor of each of subpixels for displaying an image, and reference lines connected to a sensing transistor of each of the subpixels, a data driver configured to supply a data voltage to the data lines and supplying a reference voltage to the reference lines, and a timing controller configured to control the data driver, sense a reference voltage deviation of each of the reference lines changed independent from a driving characteristic of a subpixel by supplying the reference voltage to the reference lines without supplying the data voltage to the data lines, and compensate for the reference voltage deviation.
