Patent ID: 8026866

Claim:
A method for applying the same dithering table to a first display panel and a second display panel, wherein: the first display panel comprises a plurality of pixels, which comprises K colors numbered as 1 to K; the second display panel comprises a plurality of pixels, which comprises K colors numbered as 1 to K; and the dithering table comprises M×N dithering operators, wherein the pixels in each of rows of each of the first display panel and the second display panel are arranged in a cyclic order of the first color pixel→the second color pixel→ . . . the K th color pixel →the first color pixel . . . , and the colors of the i th row of the first pixels of the first display panel are different from the colors of the i th row of the first pixels of the second display panel, the method for applying the same dithering table comprising the steps of: providing a dot count p, wherein the dot count p is an absolute value of a difference between the color number of the i th row, j th column of pixel of the first display panel and the color number of the i th row, j th column of pixel of the second display panel; and substituting the first 1 to (M−p) th pixels into the (p+1) th to M th dithering operators of the q th row of the dithering table, and then substituting the (r×M−p+1) th to the ((r+1)×M−p) th pixels into the first to M th dithering operators of the q th row of the dithering table when the i th row of pixel data of the second display panel is dithered, wherein K, M, N, i, j, p and r are natural numbers, and 0<p<M, 0<q≦N, r>0 and M≧K.
