    Abstract: A display device is disclosed that includes a display panel, a timing controller, and a data driver. The display panel includes a plurality of pixels. The timing controller is configured to calculate an on-pixel ratio of first image data and correct the first image data into second image data based on the on-pixel ratio. The data driver is configured to generate a data signal based on the second image data and provide the data signal to the pixels. The timing controller calculates the second image data by estimating a temperature of the display panel using the on-pixel ratio and gamma-correcting the first image data in response to the temperature.

    Abstract: A display device may include a display panel including a plurality of pixels. An interpolator may be configured to generate a first voltage value corresponding to an input data value using a preset gamma lookup table. A gamma compensator may be configured to, based on a dimming value, select at least one of a plurality of preset dimming lookup tables, and may calculate a first output data value by correcting the first voltage value based on the at least one dimming lookup table. A gamma voltage generator may be configured to generate a plurality of gamma voltages having a linear relationship. A data driver may be configured to select a first gamma voltage from among the gamma voltages based on the first output data value, and provide the first gamma voltage, as a data voltage, to the display panel.

    Abstract: A display device is disclosed. The display device comprises a display panel whose luminance changes from a start luminance to a target luminance lower than the start luminance and which displays an image, wherein the image comprises a start frame having the start luminance and a start gamma, a target frame having the target luminance and a target gamma, and a plurality of intermediate frames sequentially placed between the start frame and the target frame, where a difference in the luminance of the display panel between adjacent frames is reduced.
