Abstract:
Examples are disclosed that relate to backlit electronic displays that may help to avoid apparent non-uniform image brightness across a displayed image. One example provides an electronic display comprising a light guide, an image-forming layer, and a light-steering layer. The light guide is configured to release light over a display area. The image-forming layer is configured to form a display image by modulating the light released by the light guide. The light-steering layer is configured to steer together the light released from a peripheral region of the light guide and the light released from a central region of the light guide.
