Patent ID: 8094172

Claim:
An image display device that drives a display panel based a plurality of sub-frame image data produced from a frame image data representing an image of one screen to display the image, wherein the display panel comprises a matrix of N columns and M rows of pixels, and the frame image data comprises an array of N*K columns and M rows of pixel data, where K is an integer greater than 1, the image display device comprising: a dividing unit configured to divide the frame image data into K number of sub-frame image data, wherein each of the K sub-frame image data is formed by an array of N columns and M rows of pixel data, such that n th column of pixel data of k th sub-frame image data corresponds to (K*n−(K−k)) th column of pixel data of the frame image data and m th row of pixel data of the k th sub-frame image data corresponds to m th row of pixel data of the frame image data, for each n between 1 and N and each m between 1 and M and each k between 1 and K; and a panel drive controlling unit configured to consecutively drive the sub-frame image data into the display panel, such that the pixel data of the n th column and the m th row of a first sub-frame image data is applied to the pixel corresponding to the n th column and the m th row of the display panel, for each n of the N columns and for each m of the M rows, and the pixel data of the n th column and the m th row of remaining other sub-frame image data is distributed between a first pixel corresponding to the n th column and the m th row of the display panel and a second pixel corresponding to the (n+1) th column and the m th row of the display panel in a predetermined ratio, for each n of the N columns and for each m of the M rows.
