An electronic device may have a display with an array of display pixels. To increase the efficiency of the display, the display may also include an array of microlenses. Each microlens may overlap and focus light from a respective pixel. Pixels for one of the colors of light may have a high aspect ratio. These pixels may be covered by two microlenses or a single cylindrical microlens. The microlens dimensions may be tuned to mitigate non-uniformities in the brightness profiles of the pixels. The microlens edges may be laterally shifted towards or away from the center of the light-emitting areas to either reduce or increase the focusing power of the microlens. The microlenses and color filter elements in each pixel may also be shifted to account for the chief ray angle of the display.
