Abstract
Official abstract text for this publication.
To reduce a pseudo contour which occurs when displaying by a time gray scale method. When gradation is expressed with an n bit, bits each of which is shown by a binary of the gray scales are divided into three bit groups, and one frame is divided into two subframe groups. Then, a (0<a<n) subframes corresponding to bits belonging to a first bit group are divided into three or more, each about half of which is arranged in each subframe group; b (0<b<n) subframes corresponding to bits belonging to a second bit group are divided into two, each one of which is arranged in each the subframe group; and c (0≦c<n and a+b+c=n) subframes corresponding to bits belonging to a third bit group are arranged in at least one of the subframe groups. And then, an overlapped time gray scale method is applied in each subframe group to express gradation.
First claim
Opening claim text (preview).
What is claimed is: 1. A driving method of a display device for expressing gradation by dividing one frame into a plurality of subframes, in the case where gradation is expressed with an n bit (here n is an integer), the display device comprising: a pixel portion comprising pixels over a substrate, each of the pixels comprising a capacitor and a bottom-gate transistor comprising a compound semiconductor; a memory; and a circuit configured to output signals to the substrate by…
