Abstract

A pixel arrangement structure of an OLED display is provided. The pixel arrangement structure includes: a first pixel having a center coinciding with a center of a virtual square; a second pixel separated from the first pixel and having a center at a first vertex of the virtual square; and a third pixel separated from the first pixel and the second pixel, and having a center at a second vertex neighboring the first vertex of the virtual square.

Claims

1. A pixel arrangement structure of an organic light emitting diode display, comprising:

a first pixel having a center coinciding with a center of a virtual square;

a second pixel separated from the first pixel and having a center at a first vertex of the virtual square; and

a third pixel separated from the first pixel and the second pixel, and having a center at a second vertex neighboring the first vertex of the virtual square.

2. The pixel arrangement structure of claim 1, wherein

the second pixel comprises a pair of second pixels, and

the second pixels are separated from each other by the first pixel.

3. The pixel arrangement structure of claim 2, wherein

the third pixel comprises a pair of third pixels, and

the third pixels are separated from each other by the first pixel.

4. The pixel arrangement structure of claim 3, wherein the second pixels and the third pixels enclose the first pixel in the virtual square.

5. The pixel arrangement structure of claim 4, wherein

the first pixel, the second pixels, and the third pixels have polygonal shapes, and

the second pixels and the third pixels have a larger area than the first pixel.

6. The pixel arrangement structure of claim 5, wherein

the first pixel has a quadrilateral shape, and

the second pixels and the third pixels have hexagonal or octagonal shapes.

7. The pixel arrangement structure of claim 6, wherein the second pixels and the third pixels have octagonal shapes.

8. The pixel arrangement structure of claim 7, wherein:

the second pixels and the third pixels have a same area, and

a distance between the first pixel and the second pixels, a distance between the first pixel and the third pixels, and a distance between the second pixels and the third pixels is a same first length.

9. The pixel arrangement structure of claim 8, wherein

the first pixel comprises a plurality of first pixels,

the plurality of first pixels have a same quadrilateral shape, and

a distance between neighboring ones of the plurality of first pixels is a second length that is longer than the first length.

10. The pixel arrangement structure of claim 6, wherein

the second pixels have a larger area than the third pixels,

a distance between the second pixels and the third pixels is a first length, and

a distance between the first pixel and the second pixels, and a distance between the first pixel and the third pixels is a same second length.

11. The pixel arrangement structure of claim 10, wherein

the first pixel comprises a plurality of first pixels,

the plurality of first pixels have a same quadrilateral shape, and

a distance between neighboring ones of the plurality of first pixels is a third length that is longer than the first length and the second length.

12. The pixel arrangement structure of claim 10, wherein

the first pixel comprises a plurality of first pixels,

neighboring ones of the plurality of first pixels have quadrilateral shapes that are symmetrical to each other, and

a distance between the neighboring ones of the plurality of first pixels is a third length that is longer than the first length and the second length.

13. The pixel arrangement structure of claim 6, wherein

the first pixel comprises a plurality of first pixels, and

neighboring ones of the plurality of first pixels have quadrilateral shapes that are symmetrical to each other.

14. The pixel arrangement structure of claim 13, wherein the second pixels have a larger area than the third pixels.

15. The pixel arrangement structure of claim 13, wherein the third pixels have a larger area than the second pixels.

16. The pixel arrangement structure of claim 5, wherein

the first pixel has a octagonal shape, and

the second pixels and the third pixels have quadrilateral shapes.

17. The pixel arrangement structure of claim 16, wherein

the second pixels have a larger area than the third pixels,
