Abstract: An organic light-emitting diode display may have thin-film transistor circuitry formed on a substrate. The display and substrate may have rounded corners. A pixel definition layer may be formed on the thin-film transistor circuitry. Openings in the pixel definition layer may be provided with emissive material overlapping respective anodes for organic light-emitting diodes. A cathode layer may cover the array of pixels. A ground power supply path may be used to distribute a ground voltage to the cathode layer. The ground power supply path may be formed from a metal layer that is shorted to the cathode layer using portions of a metal layer that forms anodes, may be formed from a mesh shaped metal pattern, may have L-shaped path segments, and may include laser-deposited metal on the cathode layer. Data lines may be formed from metal layers in the active area to accommodate the rounded corners of the display.

Abstract: Organic light emitting diode (OLED) backplanes and fine metal masks (FMMs) are described. In an embodiment, an OLED backplane includes an array of raised bottom electrodes, and an FMM includes an array of pixel openings and an array of recesses. The FMM can be positioned over the backplane such that the pixel openings are over the raised bottom electrodes onto which a layer is to be evaporated, and the recesses are over the raised bottom electrodes that are to be protected from the evaporated species.

Abstract: 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.
