Light Guide Plates and Optical Films with Mating Alignment Features |
摘要 |
Electronic devices may be provided with backlight structures that provide backlight illumination for a display. The backlight structures include a light source such as an array of light-emitting diodes that launches light into an edge of a light guide plate. The light guide plate distributes the light laterally across display layers in the display. One or more optical films such as brightness enhancement films and diffuser layers are interposed between the display layers and the light guide plate. The light guide plate includes light guide plate alignment features that mate with corresponding optical film alignment features in the optical films. The light guide plate alignment features may be protrusions that extend into openings such as notches or holes in the optical films. The light guide plate may have a protruding portion that extends around a periphery of the light guide plate and surrounds a perimeter of the optical films. |
