  • Display device and driving method of the same
    Patent number: 11100871
    Abstract: The display device also includes a threshold voltage sensor configured to sense a threshold voltage of a white light emitting element included in the white sub-pixel, a data compensation unit configured to correct data signal depending on a variation in the threshold voltage and generate compensated data signal and a data driver configured to generate a data voltage according to the compensated data signal and output the data voltage to the display panel. The data compensation unit calculates an initial white gain depending on the variation in the threshold voltage. Therefore, the lifetime of the display device can be improved.
