Patent ID: 7071902

Claim:
An image display apparatus, in which one TV field period is divided into a plurality of sub-fields that are each given a different luminance weight and are arranged in ascending or descending order of luminance weight, when S denotes a sum of luminance weights of the plurality of sub-fields and R is within a range from 0 to S, a gray level corresponding to R is expressed by selecting sub-fields whose luminance weights, when added together, are closest to R, characterized in that when the plurality of sub-fields are arranged in ascending order of luminance weight with the ith smallest luminance weight being denoted by W i , “n” exists such that W 1 +W 1 +W 2 + . . . . . . . . +W n <W n+1 , where 1≦n and n+1≦the number of the plurality of sub-fields.
