Publication number: 20060066643Abstract: 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.
