First Claim
1. A display device comprising:
- a pixel that is defined by a plurality of sub-pixels;
whereinthe sub-pixels include a red sub-pixel representing red, a green sub-pixel representing green, a blue sub-pixel representing blue, and a yellow sub-pixel representing yellow, and when the pixel represents white, the luminance of the red sub-pixel is lower than its luminance corresponding to a highest gray scale level; and
when the pixel represents white, a sum of the luminances of the red, the green, the blue, and the yellow sub-pixels is about 90% or more of a sum of the luminances of the red, the green, the blue, and the yellow sub-pixels at corresponding highest gray scale levels thereof.

Abstract
A display device has a pixel that is defined by a plurality of sub-pixels. The sub-pixels include a red sub-pixel representing red, a green sub-pixel representing green, a blue sub-pixel representing blue and a yellow sub-pixel representing yellow. When the pixel represents white, the luminance of the red sub-pixel is lower than its luminance corresponding to the highest gray scale level. In one embodiment, when the pixel represents white, the luminance of the red sub-pixel is preferably in the range of 25% to 96% of its luminance corresponding to the highest gray scale level. Also, the color temperature of white represented by the pixel is preferably higher than 4200 K, more preferably higher than 5000 K.

8. A display device comprising a pixel and conducting a display operation using a frame that includes a red subframe to make the pixel represent red, a green subframe to make the pixel represent green, a blue subframe to make the pixel represent blue, and a yellow subframe to make the pixel represent yellow;
- wherein
when the pixel represents white in the frame, the luminance of the pixel in the red subframe is lower than its luminance corresponding to a highest gray scale level; and when the pixel represents white in the frame, a sum of the luminances of the red, the green, the blue, and the yellow subframes is about 90% or more of a sum of the luminances of the red, the green, the blue, and the yellow subframes at corresponding highest gray scale levels thereof.
