    Abstract: A first gamma offset corresponding to a first gamma reference voltage is determined by performing a multi-time programmable (“MTP”) operation with respect to a first reference gray value, a second gamma offset corresponding to a second gamma reference voltage is determined by performing the MTP operation with respect to a second reference gray value greater than the first reference gray value, a base gamma offset is determined by performing the MTP operation with respect to a base reference gray value smaller than the first reference gray value. and low gray voltages corresponding to low gray values smaller than the first reference gray value are generated based on the base gamma offset, the first gamma offset and the second gamma offset.

    Abstract: A display device includes a display panel, a dimming controller, and a panel driver. The display panel includes a plurality of pixels. The dimming controller generates at least one temporary voltage set by performing a first interpolating operation using a (j)th band voltage set and a (j+1)th band voltage set among first through (i)th band voltage sets corresponding to first through (i)th dimming bands, respectively, and generates a grayscale gamma voltage set corresponding to target luminance by performing a second interpolating operation using the temporary voltage set and the (j)th band voltage set. The panel driver drives the display panel by converting image data into a data signal based on the grayscale gamma voltage set and by providing the data signal to the pixels.
