摘要:
This disclosure provides systems, methods and apparatus, including a display device that includes an overlying holographic film. In one aspect, the holographic film includes a hologram that is configured to turn light incident on the film. The light is turned towards the display device at desired angles. The display can be formed of interferometric modulators and the turned light can be reflected off the display, and towards a viewer, to form an image. For light that is incident on the film at angles outside of a view cone, the holographic film is provided with holographic light turning features that turn this light so that it is reflected off the display at angles within a view cone of the display.
