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.
Claims20
A pixel arrangement structure of an organic light emitting diode (OLED) display, the pixel arrangement structure comprising a plurality of individually addressable pixels for displaying an image, the individually addressable pixels being minimum addressable units of the OLED display and comprising:
- a plurality of first pixels, wherein the first pixels have a shape comprising edges;
- a plurality of second pixels;
- and
- a plurality of third pixels,
- wherein the OLED display comprises a pixel defining layer defining areas of the first pixels, the second pixels, and the third pixels,
- wherein the first pixels, the second pixels, and the third pixels are configured to emit different color lights having respective colors, and
- wherein only one of the second pixels or only one of the third pixels is included in a virtual quadrangle containing at least some of the edges of a group of four neighboring ones of the plurality of first pixels, all portions of all others of the second pixels and the third pixels being outside of the virtual quadrangle,
- wherein a shortest distance in a direction parallel to any side of the virtual quadrangle between two of the group of four neighboring ones of the plurality of first pixels is greater than a shortest distance between the only one of the second pixels or the only one of the third pixels included in the virtual quadrangle and a nearest one of the second pixels or the third pixels in a direction perpendicular to any side of the virtual quadrangle, and
- wherein a pair of first pixels on respective sides of one of the second pixels or the third pixels are symmetric with each other with respect to the one of the second pixels or the third pixels.
An organic light emitting diode (OLED) display comprising a plurality of pixels for displaying an image, the plurality of pixels being individually addressable pixels for displaying an image, the individually addressable pixels being minimum addressable units of the OLED display and comprising:
- a plurality of first pixels to produce light of a first color;
- a plurality of second pixels to produce light of a second color that is different from the first color;
- and
- a plurality of third pixels to produce light of a third color that is different from the first color and the second color,
- wherein the plurality of pixels is organized into a plurality of first pixel rows and a plurality of second pixel rows that are alternately arranged along a column direction,
- wherein each of the first pixel rows comprises some of the first pixels and some of the second pixels that are alternately arranged along a row direction substantially perpendicular to the column direction,
- wherein each of the second pixel rows comprises some of the first pixels and some of the third pixels that are alternately arranged along the row direction,
- wherein the first pixels in the first pixel rows are entirely outside a region extending in the row direction and completely overlapping, in the column direction, the third pixels in one of the second pixel rows that is adjacent to the first pixel rows,
- wherein a shortest distance between two nearest ones of the first pixels in a third direction crossing the row direction and the column direction is greater than a shortest distance between one of the second pixels and one of the third pixels that are nearest each other in the third direction, and
- wherein a first pixel of the first pixels is symmetric with respect to at least one of an axis extending in the row direction or an axis extending in the column direction.
