Patent ID: 8223098

Claim:
An image displaying method for displaying an image corresponding to an input image signal, the method comprising: dividing one frame period into a plurality of sub-frame periods including at least one sub-frame period A and at least one sub-frame period B; and displaying the image based upon an image signal supplied in the plurality of sub-frame periods, such that the input image signal always has an image signal level greater than or equal to the image signal level of the image signal supplied in the sub-frame period A or B and always has an image signal level less than or equal to the image signal level of the image signal supplied in the other one of the sub-frame period A or B, wherein the image signal supplied in the sub-frame period A varies gradually throughout the sub-frame period A and wherein the image signal supplied in the sub-frame period B is of a value which maintains the supplied image signal at a value between or equal to the image signal supplied in the sub-frame periods A and B, and wherein the following condition is satisfied upon input of an image signal of a frame period in which a region supplied with an image signal α and a region supplied with an image signal β satisfying α<β are adjacent to each other, α≦αA<β, αB≦α, where αA expresses an image signal in the sub-frame period A and αB expresses an image signal for image output in the sub-frame period B, in each pixel in the region supplied with an image signal α, α<βA≦β, β≦βB, where βA expresses an image signal for image output in the sub-frame period A and βB expresses an image signal for image output in the sub-frame period B, in each pixel in the region supplied with an image signal β.
