LIQUID CRYSTAL DISPLAY DEVICE, IMAGE SIGNAL CORRECTION CIRCUIT, IMAGE SIGNAL CORRECTION³@METHOD, AND ELECTRONIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To eliminate a deterioration in display quality caused by so-called vertical cross-talk by correcting image signals. SOLUTION: The liquid crystal display device is provided with a subtracter 322 that calculates the difference between an image signal and a reference signal. The image signal has information corresponding to the density of a pixel arranged in a matrix extending in row and column directions and being supplied in synchronization with horizontal scanning in the row direction and vertical scanning in the column direction. The reference signal Ref has information corresponding to a reference density. The liquid crystal display device is also provided with a first accumulator group 332 and a second accumulator group 334 that accumulate the difference for one vertical scanning period at every column and an adder 328 that adds a value corresponding to an accumulated value in accordance with a column to the image signal DV of the column and corrects the image signal.
