  • Patent number: 9171513
    Abstract: A luminance adjustment part includes a luminance determination part and a data compensation part. The luminance determination part may determine a control value for controlling luminance of a backlight assembly using linear image data that has a linear luminance profile and is generated by performing a de-gamma process on a first copy of input image data that has a nonlinear luminance profile. The compensation part may compensate pixel data that corresponds to pixels of a display panel using the control value, the pixel data being generated using a second copy of the input image data. Thus, color distortion of a displayed image as perceived by a viewer may be minimized when power consumption of a display apparatus that includes the display panel is decreased.
