    摘要: 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.

    摘要: A display device may include a timing controller, a data driver and a plurality of pixels. The timing controller supplies a clock training pattern over a data/clock signal line in a first time period, and supplies pixel/control data over the data/clock signal line in a second time period. The data driver generates a clock signal, using the clock training pattern, in the first period, and generate a plurality of data voltages based on the plurality of pixel data, using the clock signal, in the second period. The plurality of pixels receive the plurality of data voltages and emit corresponding light. During the second period, the data driver outputs a feedback signal to the timing controller indicating that the locking of the clock signal has failed. The timing controller re-supplies the clock training pattern in response to the feedback signal.

    摘要: A display device includes a display panel including a plurality of pixels connected to data lines and sensing lines, a data driver including a plurality of buffer amplifiers which supplies a first sensing voltage to the data lines during a first sensing period and a sensor which receives a first sensing signal from the pixels through the sensing lines during the first sensing period, and a global amplifier which supplies a second sensing voltage to the data lines during a second sensing period different from the first sensing period. The sensor receives a second sensing signal corresponding to the second sensing voltage from the pixels through the sensing lines during the second sensing period, and generates compensation data based on a difference value between the first sensing signal and the second sensing signal.

    摘要: 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.
