Abstract
A luminance compensator includes a memory device and a luminance compensation circuit. The memory device stores a plurality of luminance compensation data and provides first luminance compensation data and second luminance compensation data among the plurality of luminance compensation data in response to a frame rate dimming-on signal. The first luminance compensation data corresponds to a first frame rate. The second luminance compensation data corresponds to a second frame rate. The plurality of luminance compensation data is for compensating luminance of at least one region that operates with a plurality of frame rates. The frame rate dimming-on signal represents time intervals in which frame rates of the at least one region are gradually changed. The luminance compensation circuit generates third luminance compensation data in response to the frame rate dimming-on signal, the first luminance compensation data, and the second luminance compensation data.
