Abstract
A pixel arrangement structure of an organic light emitting diode (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. The first pixel, the second pixel, and the third pixel have polygonal shapes.
Claims22
A pixel arrangement structure comprising a plurality of individually addressable pixels for displaying an image on an organic light emitting diode (OLED) display, the plurality of individually addressable pixels being minimum addressable units of the OLED display and comprising a plurality of first pixels, a plurality of second pixels, and a plurality of third pixels,
- wherein the plurality of first pixels, the plurality of second pixels, and the plurality of third pixels are spaced apart from one another,
- wherein four of the first pixels overlap with vertexes, respectively, of a first virtual square, and one of the second pixels overlaps with a center of the first virtual square,
- wherein four of the first pixels overlap with vertexes, respectively, of a second virtual square, and one of the third pixels overlaps with a center of the second virtual square,
- wherein the first virtual square and the second virtual square are adjacent to one another along a first direction,
- wherein the first virtual square and the second virtual square share two common vertexes at which two of the first pixels are located,
- wherein the first virtual square and the second virtual square have a same size that is a smallest size whereby, while the first virtual square and the second virtual square share the two common vertexes, the first virtual square touches the four of the first pixels that respectively overlap with the vertexes of the first virtual square and the second virtual square touches the four of the first pixels that respectively overlap with the vertexes of the second virtual square,
- wherein the first virtual square completely surrounds the one of the second pixels, and the second virtual square completely surrounds the one of the third pixels, and
- wherein a largest virtual square that touches the four of the first pixels that respectively overlap with the vertexes of the first virtual square is offset from another one of the third pixels adjacent to the one of the second pixels along a second direction perpendicular to the first direction.
An organic light emitting diode (OLED) display comprising a plurality of individually addressable pixels for displaying an image, the plurality of individually addressable pixels being minimum addressable units of the OLED display and being organized into a plurality of pixel rows comprising a plurality of first pixel rows and a plurality of second pixel rows that are alternately arranged along a first direction,
- wherein each of the first pixel rows is configured to produce light of a first mixed color when all of the pixels arranged along a second direction perpendicular to the first direction on the first pixel row are concurrently driven,
- wherein each of the second pixel rows is configured to produce light of a second mixed color different from the first mixed color when all of the pixels arranged along the second direction on the second pixel row are concurrently driven,
- wherein some of the pixels on the plurality of first pixel rows are configured to produce light having the same color as some of the pixels on the plurality of second pixel rows,
- wherein the some of the pixels on the plurality of first pixel rows configured to produce light having the same color as the some of the pixels on the plurality of second pixel rows are elongated in the first direction, and the some of the pixels on the plurality of second pixel rows having the same color are elongated in the second direction,
- wherein the pixels on the plurality of first pixel rows have two different shapes, and the pixels on the plurality of second pixel rows have two different shapes,
- wherein the first pixel rows comprise first pixels configured to produce light having a first color and second pixels configured to produce light having a second color different from the first color, the second pixels on the first pixel rows have a largest first width in the first direction, and the first pixels on the first pixel rows have a largest second width in the first direction, the largest first width being larger than the largest second width, and
- wherein the plurality of individually addressable pixels are spaced apart from one another.
