Patent ID: 8754913

Claim:
A subpixel arrangement structure for a display device, comprising: a plurality of pixel groups each of which comprises four unit pixels, wherein the four unit pixels includes a first unit pixel, a second unit pixel positioned adjacent to the first unit pixel in a direction of a row axis, a third unit pixel positioned adjacent to the first unit pixel in a direction of a column axis that is perpendicular to the row axis, and a fourth unit pixel positioned adjacent to the second unit pixel in the direction of the column axis, wherein each unit pixel has a red subpixel, a green subpixel and a blue subpixel which form a delta arrangement structure, wherein openings of the red and green subpixels of each unit pixel are substantially aligned along the direction of the column axis, wherein an opening of the blue subpixel of each unit pixel are substantially aligned along the direction of the column axis and staggered along the direction of the row axis or are substantially aligned along the direction of the row axis and staggered along the direction of the column axis, and wherein two of the unit pixels, that are positioned adjacent to each other in the direction of the column axis or the direction of the row axis, share one blue subpixel with each other, wherein the first unit pixel includes a first red subpixel, a first green subpixel positioned at the lateral side of the first red subpixel, and a first blue shared subpixel positioned at the lower side of the first green subpixel, thereby forming a first delta arrangement, wherein the second unit pixel includes a second red subpixel, a second green subpixel positioned at the lateral side of the second red subpixel, and the first blue shared subpixel positioned at the lower side of the second red subpixel, thereby forming a second delta arrangement, wherein the third unit pixel includes a third red subpixel, a third green subpixel positioned at the lateral side of the third red subpixel, and a second blue shared subpixel positioned at the lower side of the third red subpixel, thereby forming a third delta arrangement, that is substantially the same as the second delta arrangement, and wherein the fourth unit pixel includes a fourth red subpixel, a fourth green subpixel positioned at the lateral side of the fourth red subpixel, and a third blue shared subpixel positioned at the lower side of the fourth green subpixel, thereby forming a fourth delta arrangement, that is substantially the same as the first delta arrangement.
