Abstract

Disclosed herein is a color display apparatus which has a pixel pattern including a plurality of repeating units of a pixel array, wherein each of the plurality of repeating units of the pixel array is composed of at least five sub-pixels while including at least one sub-pixel from a first to fourth sub-pixel, respectively, the first sub-pixel representing a red color (R), the second sub-pixel representing a green color (G), the third sub-pixel representing a blue color (B), and the fourth sub-pixel representing a mixed color of at least two colors from among the R, G, and B, and each of the plurality of repeating units of the pixel array corresponds to at least two image pixels.

Claims

1. A color display apparatus comprising a pixel pattern including a plurality of repeating units of a pixel array,

wherein each of the plurality of repeating units of the pixel array is composed of at least five sub-pixels while including at least one sub-pixel from a first to fourth sub-pixel, respectively, the first sub-pixel representing a red color (R), the second sub-pixel representing a green color (G), the third sub-pixel representing a blue color (B), and the fourth sub-pixel representing a mixed color of at least two colors from among the R, G, and B, and

each of the plurality of repeating units of the pixel array corresponds to at least two image pixels.

2. The apparatus of claim 1, wherein the fourth sub-pixel represents a white color (W).

3. The apparatus of claim 1, wherein an occupancy ratio of the fourth sub-pixel to the total sub-pixels is ≦

20%.

4. The apparatus of claim 1, wherein at least one sub-pixel is shared so as to correspond to two different image pixels.

5. The apparatus of claim 1, wherein the repeating unit of the pixel array includes 5N sub-pixels, and corresponds to 2N image pixels, where N is a natural number.

6. The apparatus of claim 1, wherein each number of sub-pixels of at least any two sub-pixels from the first to fourth sub-pixel included in the repeating unit of the pixel array is mutually different.

7. The apparatus of claim 1, wherein sub-pixels included in the repeating unit of a pixel array are arranged in a row.

8. The apparatus of claim 1, wherein sub-pixels included in the repeating unit of the pixel array are arranged in two rows.

9. The apparatus of claim 1,

wherein the repeating unit of the pixel array includes at least two sub-pixels from the first to third sub-pixel, respectively,

wherein sub-pixels representing an identical color are arranged to be mutually adjacent.

10. The apparatus of claim 1, wherein the repeating unit of the pixel array includes at least two sub-pixels from the first to third sub-pixel, respectively, and the sub-pixels representing an identical color are prevented from being arranged to be mutually adjacent.

11. The apparatus of claim 1, wherein the repeating unit of the pixel array includes two fourth sub-pixels, and the two fourth sub-pixels are arranged to be mutually adjacent.

12. A color display apparatus comprising a pixel pattern including a plurality of repeating units of a pixel array,

wherein each of the plurality of repeating units of the pixel array is composed of a total number of ten sub-pixels while including at least one sub-pixel from a first to fourth sub-pixel, respectively, the first sub-pixel representing a red color (R), the second sub-pixel representing a green color (G), the third sub-pixel representing a blue color (B), and the fourth sub-pixel representing a mixed color of at least two colors from among the R, G, and B, and

each of the plurality of repeating units of the pixel array corresponds to four image pixels.

2.

14. The apparatus of claim 12, wherein the repeating unit of the pixel array includes the first, second, third, and fourth sub-pixels, respectively, to have a ratio of the number of the first to fourth sub-pixel of 2:

4;

2;

2.

15. The apparatus of claim 12, wherein the repeating unit of the pixel array includes the first, second, third, and fourth sub-pixels, respectively, to have a ratio of the number of the first to fourth sub-pixel of 3:

3;

3;

1.

16. The apparatus of claim 12, wherein the repeating unit of the pixel array includes the first, second, third, and fourth sub-pixels, respectively, to have a ratio of the number of the first to fourth sub-pixel of 3:

4;

2;

1.

17. A color display apparatus comprising a pixel pattern including a plurality of repeating units of a pixel array,
