Abstract
A display device includes 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, and each of the pixels sharing the sub-pixels with an adjacent one of the pixels.
Claims16
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.

A driving method of a display device, comprising:
- storing first, second, third, and fourth input data signals;
- 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
- displaying images through 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.
