Abstract: A display device includes an image controller that analyzes first image data to determine whether a same image is displayed for no less than a predetermined threshold time. The image controller sets a low grayscale region having grayscale values of no more than a predetermined threshold low grayscale value when the same image is displayed for no less than a threshold time. The image controller then receives second image data and transmits a control signal to allow a transistor hysteresis reset signal to be transmitted to pixels of the display in the low grayscale region. A data driver transmits the transistor hysteresis reset signal to the pixels in the low grayscale region based on the control signal.

Abstract: A method for controlling a display device includes adjusting the luminance value of input data by a first method when the luminance value is greater than or equal to a predetermined number of nits, and adjusting the luminance value by a second method when the luminance value is less than the predetermined number of nits. The first method reduces the luminance value by a first predetermined percentage. The second method adjusts the luminance value to a first value corresponding to a predetermined luminance value set for the predetermined number of nits, and then reduces the first value by a second predetermined percentage different from the first predetermined percentage. The predetermined number of nits may be 2 nits or another number of nits.

Abstract: A display device includes at least a first luminance range and a second luminance range which includes a luminance different from the first luminance range. In a boundary area of a second dimming range corresponding to the second luminance range and which is adjacent to a first dimming range corresponding to the first luminance range, a reference luminance emitted from a pixel is maintained as a first constant luminance value, and an off-duty number, which is the number of periods in which the pixel is turned off during one frame, is gradually increased by an emission control signal.

Abstract: A data driver includes a first and second data voltage generator and a third data voltage generator. The first and second data voltage generator generates a first data voltage corresponding to a first grayscale value and a second data voltage corresponding to a second grayscale value lower than the first grayscale value based on a reference voltage. The third data voltage generator generates a third data voltage corresponding to a third grayscale value lower than the second grayscale value based on a voltage level difference between the first data voltage and the second data voltage.
