Patent ID: 6965358

Claim:
A display apparatus for performing gray scale display by dividing one field of an image into a plurality of weighted subfields and by controlling each subfield to one of emit and not emit light based on a gray scale level of a pixel in the image, said apparatus comprising: a converter for selectively converting the gray scale level of the pixel to one of a gray scale level in a first gray scale group or a gray scale level in a second gray scale group, said first gray scale group including a plurality of gray scale levels to be used for actual display, the gray scale level in the first gray scale group being expressed by a combination of the subfields, said second gray scale group including a plurality of gray scale levels each of which is interspersed in the gray scale levels in the first gray scale group; and a first diffuser for generating a video signal, said video signal displaying a gray scale level obtained by the converter when the gray scale level obtained by the converter is in the first gray scale group, and when the gray scale level obtained by the converter is in the second gray scale group, the diffuser generating a video signal displaying a gray scale level obtained by diffusing a predetermined value corresponding to the gray scale level in the second gray scale group.
