Patent ID: 8085282

Claim:
An image display apparatus comprising: a plurality of pixels; a common wiring to which a first set of pixels are connected in common; a plurality of modulation signal wirings, each of which is connected to a set of pixels, and applying a modulation signal for modulating a lighting time to the plurality of pixels; a correction circuit for correcting inputted data and outputting the corrected data; and a modulation signal output circuit for outputting the modulation signal on the basis of the data that is corrected by the correction circuit, wherein when M pieces of periods in a period that the modulation signal can be outputted are referred to as first to Mth periods, where M is defined to be a natural number and p is defined to be a natural number in 2≦p≦M, the correction circuit has: a calculation unit for calculating a value representing luminance during a first period of each of the plurality of pixels on the basis of the inputted data and calculating a value representing luminance during a pth period in sequence; and an accumulation unit for accumulating the value representing the luminance during each period for each pixel; and wherein on the basis of a result of determining a pixel that the accumulated value thereof exceeds a value representing luminance that is indicated by the inputted data thereof, a value representing the luminance during the pth period is calculated.
