Electronic device with illuminated logo structures
First Claim
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.

Abstract
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.

12. An electronic device, comprising:
-
an opaque housing having an opening; a housing structure in the opening; a light source; a light guide structure having first and second opposing surfaces; a liquid crystal display module; a light guide plate; and a reflector that covers the first surface, wherein the light guide structure conveys light from the light source through the housing structure in the opening, wherein the light guide structure comprises light-leakage promotion structures within a region at the second surface of the light guide structure that is defined by the opening in the housing structure, wherein the second surface of the light guide structure has a planar portion, wherein the second surface of the light guide structure has a plurality of protrusions that extend towards the housing structure, wherein the plurality of protrusions extend past the planar portion of the second surface of the light guide structure, wherein the plurality of protrusions form the light-leakage promotion structures, wherein the light guide plate is interposed between the reflector and the liquid crystal display module and provides backlight to the display module, wherein the reflector comprises a metal coating on the first surface of the light guide structure, wherein the light guide plate receives the backlight from the light source, wherein the light guide structure comprises a clear plastic sheet, wherein the housing structure comprises a logo structure, wherein the light-leakage promotion structures overlap the logo structure and cause light received from the light source to pass through the housing structure, wherein the logo structure comprises translucent plastic, wherein the housing structure comprise metal, wherein the light guide structure has a width and a length, wherein the width is at least five times smaller than the length, and wherein the light guide structure routes light from a single light-emitting diode to the opening. - View Dependent Claims (14, 15)
