Abstract: An electronic device may include a stereoscopic display with a plurality of lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have different viewing zones that account for horizontal parallax as a viewer moves horizontally relative to the display. The display may be dimmed globally based on the detected vertical position of the viewer. The magnitude of dimming applied to the display may increase with increasing deviation of the viewer from a baseline viewing angle. The display may render content that compensates for the real-time vertical position of the viewer. Another option for the stereoscopic display is to include a lens film that has an array of lenses. Each lens in the array of lenses spreads light in the horizontal direction and the vertical direction.
