Electronic device with illuminated logo structures

摘要

An electronic device may have a liquid crystal display with backlight structures. The backlight structures may produce backlight that passes through the liquid crystal display. A reflector may be used to enhance backlight efficiency. The electronic device may have a housing in which the display is mounted. The housing may be formed from an opaque material such as metal. An opening may be formed in the housing. Transparent housing structures such as a transparent logo structure may be mounted in the opening of the housing. During operation, a light source may produce light that passes through the transparent logo structure. A light guide structure may be used to guide light from the light source to the transparent logo structure. The reflector may be formed from a coating of metal on the light guide structure. Light from the light source may be used to form the backlight for the backlight structures.

主权项

1. An electronic device, comprising:
a housing; a transparent housing structure mounted in an opening in the housing, wherein the transparent housing structure has a first width; a display in the housing that has a second width; a display backlight reflector that reflects backlight through the display; a light source; a first light guide structure through which light is conveyed from the light source to the display; and a second light guide structure that conveys light from the light source to the transparent housing structure, wherein the display backlight reflector is interposed between the first light guide structure and the second light guide structure, wherein the light conveyed by the second light guide structure passes through the transparent housing structure, wherein the second light guide structure has a first portion that is adjacent to the light source and has a third width, wherein the second light guide structure has a second portion that is adjacent to the transparent housing structure and has a fourth width, wherein the first width is substantially equivalent to the fourth width, wherein the second width is substantially equivalent to the third width, and wherein the fourth width is smaller than the third width.
