Organic light emitting diode display
An organic light emitting diode (OLED) display includes first pixels, second pixels, and third pixels. The OLED display includes a first column including a plurality of the first pixels alternately arranged with a plurality of the second pixels; and a second column adjacent to the first column and comprising a plurality of the third pixels. One of the first pixels and one of the second pixels in the first column correspond to more than two of the third pixels in the second column. Rendering driving is applied such that high resolution of more than 350 pixels per inch (PPI) may be realized without deterioration of the image quality while the total number of pixels is smaller than in a pentile matrix arrangement.
1. An organic light emitting diode (OLED) display comprising:
a matrix of pixels aligned in both row and column directions, each of the pixels comprising subpixels from among a group of subpixels comprising:
a first column comprising one first subpixel and one second subpixel, each of the first subpixel and the second subpixel having a first end and a second end spaced from the first end in the column direction; and
a second column comprising three to five third subpixels, each of the third pixels having a first end and a second end spaced from the first end in the column direction, all of the third subpixels having a same color, the second column being immediately adjacent to the first column at one side of the first column,
wherein the first end of the one first subpixel is directly aligned in the row direction with the first end of a first one in the column direction of the three to five third subpixels, and the second end of the one second subpixel is directly aligned in the row direction with the second end of a last one in the column direction of the three to five third subpixels, and
wherein one of the first subpixels is at a center of four nearest ones of the second subpixels located at respective vertices of a rhombus shape and one of the second subpixels is at a center of four nearest ones of the first subpixels located at respective vertices of a rhombus shape, and
wherein said one of the first subpixels and said one of the second subpixels is each configured to constitute three or more pixels, each of the three or more pixels comprising a corresponding one of the third subpixels on the second column that is immediately adjacent to the first column at the one side of the first column, and each of the third subpixels is configured to constitute only one pixel.
2. The OLED display of claim 1 ,
wherein the group of subpixels further comprises a third column comprising another second subpixel and another first subpixel,
wherein the second and first subpixels in the third column are alternately arranged with respect to the first and second subpixels in the first column.
3. The OLED display of claim 2 , wherein the group of subpixels further comprises a fourth column comprising another three to five third subpixels of the same color.
4. The OLED display of claim 2 , wherein
the first subpixels are diagonally arranged, and
the second subpixels are diagonally arranged.
5. The OLED display of claim 2 , wherein the first subpixels are alternately arranged with respect to the second subpixels in both the row and column directions.
6. The OLED display of claim 1 , wherein the one first subpixel, the one second subpixel, and one of the three to five third subpixels are configured to display different colors.
7. The OLED display of claim 6 , wherein the one first subpixel, the one second subpixel, and the one of the three to five third subpixels comprise a red subpixel, a blue subpixel, and a green subpixel, respectively.
8. The OLED display of claim 1 , wherein the one first subpixel has the same area as the one second subpixel.
9. The OLED display of claim 8 , wherein the one second subpixel has a different area than one of the three to five third subpixels.
10. The OLED display of claim 1 , wherein the one first subpixel on the first column and a first one of the three to five third subpixels on the second column are driven to act as a first pixel of the pixels by partially illuminating the one second subpixel on the first column and another second subpixel on a nearby one of columns.
11. The OLED display of claim 10 , wherein the one second subpixel and a second one of the three to five third subpixels are driven to act as a second pixel of the pixels by partially illuminating the one first subpixel on the first column and another first subpixel on the nearby one of the columns.
12. The OLED display of claim 11 , wherein a third one of the three to five third subpixels is driven to act as a third pixel of the pixels by partially illuminating the one first subpixel on the first column and another first subpixel on the nearby one of the columns and partially illuminating another second subpixel on the first column and said another second subpixel on the nearby one of the columns.
