    Abstract: A display such as a liquid crystal display may have an array of pixels that is illuminated using backlight illumination from a backlight. The backlight may have a light guide layer that distributes light from light-emitting diodes across the display. The light guide layer may have a planar portion that provides backlight illumination to the array of pixels and may have bent edge portions that curve out of the plane of the planar portion. Light scattering structures may be formed in the planar portion to extract backlight illumination from the light guide layer. A light sensor adjacent to the bent portion may monitor leaked light. The light guide layer may have two bent portions on opposing edges of the light guide layer.

    Abstract: An electronic device such as a laptop computer or other device may have a housing. A display may be coupled to the housing. The display may have a pixel array configured to display an image. Backlight illumination for the pixel array may be provide by a backlight unit. The backlight unit may have a light guide layer. A light source may provide light to an edge of the light guide layer. The light guide layer may scatter the light outwardly to serve as the backlight illumination for the pixel array. The backlight unit may have optical films interposed between the light guide layer and the pixel array. The optical films may include flexible polymer layers such as diffuser layers and prism films. The optical films may each have a bent alignment portion that bends back on itself while wrapping around an edge of the light guide layer.
