  • Patent number: 11620927
    Abstract: A display device includes a scale factor provider, a grayscale converter, and pixels. The scale factor provider calculates an n-th scale factor based on n-th input grayscales received during an n-th frame period. The grayscale converter calculates (n+p)th output grayscales by applying the n-th scale factor to (n+p)th input grayscales received during an (n+p)th frame period in a first mode. The pixels output light to display an image based on the (n+p)th output grayscales, where n is an integer greater than 0 and p is an integer greater than 1.

  • Patent number: 11501691
    Abstract: A display device may include a timing controller, a level shifter, a gate driver, and a display panel. The timing controller may generate a first on-clock signal, a first off-clock signal, and a first output control signal. The level shifter may generate a first-type gate clock signal. A rising edge of the first-type gate clock signal and a falling edge of the first-type gate clock signal may be respectively synchronized with a rising edge of the first on-clock signal and a falling edge of the first off-clock signal. The gate driver may output first-type gate signals based on the first-type gate clock signal. The display panel may include pixels. The pixels may emit lights in response to the first-type gate signals. The level shifter may partially block a pulse of the first-type gate clock signal based on the first output control signal to generate sub-pulses.
