Pixel patterns for organic light-emitting diode display
An electronic device may include a display having an array of organic light-emitting diode display pixels. The display pixels may have subpixels of different colors. The subpixels may include red subpixels, green subpixels, and blue subpixels. The subpixels may be provided with shapes and orientations that improve manufacturing tolerances. Subpixels such as green and red subpixels may have hexagonal shapes while blue subpixel structures may be provided with diamond shapes coupled in pairs to form barbell-shaped blue subpixels. Subpixels can also be angled at 45° relative to horizontal. Subpixels ma have shapes that overlap adjacent display pixels. For example, an array of display pixels that has been rotated by 45° relative to the edges of a display substrate may have blue subpixels and or red subpixels that are shared between pairs of adjacent display pixels in an at of display pixels.
