    Abstract: A control board in a display device includes terminals and a control circuit. The control circuit is configured to output a control signal an image signal through the terminals and to generate a drive voltage in response to a feedback signal, which is fed back to a second terminal of the terminals when a source voltage is applied to a first terminal of the terminals.

    Abstract: A driving controller includes an image analyzer, a grayscale setter and a time-and-space arranger. The image analyzer analyzes input image data to determine a peak luminance. The grayscale setter receives a gamma value and the peak luminance and to determine a boundary grayscale value and a minimum grayscale value. The time-and-space arranger is configured to temporally and spatially arrange first data having the boundary gray scale value and second data having the minimum grayscale value. The driving controller is configured to drive a display panel using the first data and the second data for a low grayscale range of which a grayscale is equal to or less than the boundary grayscale value and to drive the display panel based on a data signal corresponding to a grayscale value of the input image data for a normal grayscale range of which a grayscale is greater than the boundary grayscale value.
