Abstract: A flexible display encapsulation layer may be used to encapsulate and protect organic light-emitting diodes and a thin-film transistor layer on a flexible display. The flexible encapsulation layer may include a lateral dispersion layer that exhibits an anisotropic moisture diffusion characteristic. Lateral diffusion in the lateral dispersion layer is larger than vertical dispersion in a direction that runs perpendicular to the display. An inorganic conformal coating layer may cover the lateral diffusion layer and may serve as a pinhole filling layer. The pinhole filling layer may be covered with a moisture barrier layer that serves to prevent moisture from penetrating the display. A polymer protective layer may cover the moisture barrier layer and may be relatively insensitive to bending induced stress as the display is flexed.

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.

Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have a steep sidewall, a sidewall with an undercut, or a sidewall surface with a plurality of curves to disrupt continuity of the OLED layers. A control gate that is coupled to a bias voltage and covered by gate dielectric may be used to form an organic thin-film transistor that shuts the leakage current channel between adjacent anodes on the display.

Abstract: A display may have an array of pixels with light-emitting diodes that emit light to form images. The display may have a substrate with thin-film transistor circuitry for supplying signals to the light-emitting diodes. Anodes may be formed on the thin-film transistor circuitry, emissive material may be formed on the anodes, and a cathode layer may overlap the anodes. During operation, currents may flow between the anodes and the cathode layer to illuminate the diodes. An array of electrical components such as an array of light sensors in an integrated circuit may be mounted under the substrate. An array of corresponding light transmitting windows may be formed in the display each of which may allow light to pass through the display to a corresponding one of the light sensors. Light transmitting windows may be formed by patterning the cathode layer and supplying the windows with antireflection layers.

Abstract: An organic light-emitting diode display may have an array of pixels with sets of pixels arranged in rows and columns. Each set of pixels includes a red pixel, a green pixel, a blue pixel, and a white pixel. The red pixels each have a white diode and a red color filter element to impart a red color to white light from that white diode. The green pixels each have a white diode and a green color filter element to impart a green color to white light from that white diode. The white pixels each have an unfiltered white diode. The blue pixels each have an unfiltered blue diode. The unfiltered white and blue diodes do not have color filters and emit white and blue light for the white and blue pixels, respectively. The white and blue diodes may be tandem diodes having two or more emissive layers.
