    Abstract: A display device includes a display panel, a timing controller, a data driver, a gate driver and a backlight unit. The gate driver sequentially outputs gate signals to gate lines. The backlight unit performs an on-operation during a high section of a backlight control signal and an off-operation during a low section of the backlight control signal. The gate signals includes first gate signals that are output during the high section of the backlight control signal and have a first pulse width and second gate signals that are output during the low section of the backlight control signal and have a second pulse width greater than the first pulse width.

    Abstract: A display device includes a display panel displaying an image based on output image data, a voltage curve controller generating a converted peak luminance, a converted full white luminance, a converted peak grayscale, and a converted full white grayscale from a reference peak luminance and a reference full white luminance based on a gain mode and a gain value, and generating converted voltage curves including a first converted voltage curve from a first reference voltage curve based on the converted peak grayscale and the converted full white grayscale, and a driving voltage controller generating a driving voltage from the converted voltage curves based on a load and a maximum grayscale value of input image data. A voltage of the first converted voltage curve with respect to a peak grayscale is equal to a voltage of the first reference voltage curve with respect to the converted peak grayscale.

    Abstract: A display device is disclosed that includes a display panel, a data driver, a timing controller, a memory device, and a power voltage generator. The display panel includes pixels. The data driver is configured to apply data voltages to the pixels. The timing controller is configured to control the data driver, to generate a test strobe signal by shifting a phase of a strobe signal, to perform a test write operation and a test read operation with the memory device based on the test strobe signal, and to increase a power voltage when an error bit occurs in the test write operation and the test read operation. The memory device is configured to sample memory data received from the timing controller using the strobe signal and to store sampled memory data. The power voltage generator is configured to apply the power voltage to the memory device.
