Abstract:
1. A luminance adjustment part comprising: a luminance determination part configured to determine a control value for controlling luminance of a backlight assembly using linear image data, the linear image data being generated by performing a de-gamma process on a first copy of input image data, the linear image data having a linear luminance profile, the input image data having a nonlinear luminance profile; and a data compensation part configured to 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, wherein the data compensation part comprises: a luminance compensation part for multiplying a luma component of the pixel data by a luminance compensation ratio to generate a multiplication result; and a tone disappearance compensation part for compensating tone disappearance if the multiplication result is greater than a threshold value.
