Patent ID: 7889213

Claim:
A display device, comprising: a signal storing portion storing first, second, third, and fourth input data signals; an average signal generating portion averaging the first, second, third, and fourth input data signals, respectively, that are adjacent to each other along a row and a column and generating first, second, third, and fourth output data signals; and a display portion having a plurality of pixels, each of the pixels having first, second, third, and fourth sub-pixels for receiving the first, second, third, and fourth output data signals, respectively, each of the pixels sharing the sub-pixels with an adjacent one of the pixels, the first, second, third and fourth sub-pixels emitting red, green, blue and white, respectively, wherein the plurality of pixels includes (i,j) th , (i,j+1) th , (i+1,j) th and (i+1,j+1) th pixels adjacent to one another, wherein the first output data signal for the first sub-pixel of (i,j) th pixel is determined by averaging the first input data signals corresponding to the first sub-pixels of the (i,j) th , (i,j+1) th , (i+1,j) th and (i+1,j+1) th pixels, wherein the second output data signal for the second sub-pixel of (i,j) th pixel is determined by averaging the second input data signals corresponding to the second sub-pixels of the (i,j) th , (i,j+1) th , (i+1,j) th and (i+1,j+1) th pixels, wherein the third output data signal for the third sub-pixel of (i,j) th pixel is determined by averaging the third input data signals corresponding to the third sub-pixels of the (i,j) th , (i,j+1) th , (i+1,j) th and (i+1,j+1) th pixels, and wherein the fourth output data signal for the fourth sub-pixel of (i,j) th pixel is determined by averaging the fourth input data signals corresponding to the fourth sub-pixels of the (i,j) th , (i, j+1) th , (i+1,j) th and (i+1,j+1) th pixels.
