摘要： In an update operation of uneven luminance correction values, a display area of a flat display is handled as if it is divided into a plurality of small areas A to I. Then, in one update operation of the uneven luminance correction values, the uneven luminance correction values are updated only for one of these small areas A to I. Therefore, by performing the update operation of the uneven luminance correction values the same number of times as the number (9) of the small areas A to I, the uneven luminance correction values for the whole display area of the flat display are updated.

摘要： A judging unit compares data in a dither table for each display pixel with a numerical value of low-order 2 bits of an input signal (12 bits) and outputs 1 to an adder when the numerical value of the low-order 2 bits of the input signal is larger than the data in the dither table, while outputting 0 to the adder in other cases. The adder adds the value outputted from the judging unit to an uneven luminance correction value read from a correction memory, so that the uneven luminance correction value is corrected. A multiplier multiplies the input signal by the uneven luminance correction value after the correction.
