  • Patent number: 11645979
    Abstract: The present disclosure relates to a display device and a driving method thereof. The display device includes a sensing unit configured to sense electrical properties of each of pixels; a timing controller including a compensation unit configured to modulate pixel data to be written to the pixels based on sensed data from the sensing unit, a sensing error processing unit configured to analyze the sensed data to detect a sensing error, and a gate control unit configured to output a gate timing control signal; a level shifter configured to receive the gate timing control signal and output a clock; and a gate driver configured to receive the clock from the level shifter and supplying a gate signal to the gate lines, wherein the sensing error processing unit resets the timing controller when the sensing error is detected.
