The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A display may include an array of pixels such as light-emitting diode pixels. The circular polarizer may be omitted from the display to increase efficiency. A polarizer- free display may use other non-polarizer techniques to mitigate reflections of ambient light and mitigate associated diffraction artifacts. The polarizer-free display may include a black matrix, color filter element, or pixel definition layer with tapered surfaces to make changes in reflectance associated with the subpixels more gradual. Instead or in addition, a subpixel may have a footprint with one or more protrusions. Instead or in addition, different pixels may have subpixels with different elliptical footprints and/or different footprints with protrusions. Instead or in addition, the polarizer-free display may include color filter elements with concave upper surfaces. Instead or in addition, the polarizer-free display may include subpixels with varying anode heights.
