Embodiment Construction

[0039] electronic equipment such as figure 1 The device 10 may be provided with a display. The display in device 10 may include a backlight structure (sometimes referred to as a backlight unit or backlight) for backlighting the display.

[0040] figure 1 The device 10 may be a laptop computer, tablet computer, computer monitor, handheld device, gaming equipment, GPS device, cellular phone, or other electronic device.

[0041] Device 10 may include a housing, such as housing 12 . Housing 12, which may sometimes be referred to as a housing, may be formed of plastic, glass, ceramic, fiber composite, metal (eg, stainless steel, aluminum, etc.), other suitable material, or a combination of any two or more of these materials.

[0042] Housing 12 may be formed using a unitary configuration in which some or all of housing 12 is machined or molded as a single structure, or multiple structures may be used (e.g., an internal frame structure, one or more structures forming an outer hou...

Abstract

An electronic device may be provided with a display. Backlight structures may be used to provide backlight for the display. The backlight structures may include a light guide plate. A rectangular ring-shaped chassis may have a rectangular opening that receives the light guide plate. One or more edges of the chassis may be provided with an array of notches that receive light-emitting diodes or other light sources. The light sources may launch light into edge portions of the light guide plate. The chassis may include a first plastic structure such as a light reflecting structure formed from a material such as white plastic. The first plastic structure may surround two or more peripheral edges of the light guide plate. The chassis may also include a second plastic structure such as a light blocking structure formed from a material such as black plastic that helps prevent light leakage.

Description

[0001] This patent application claims priority to US Patent Application No. 13 / 229,418, filed September 9, 2011, which is hereby incorporated by reference in its entirety. Background technique [0002] This patent application relates generally to electronic devices, and more particularly to displays for electronic devices. [0003] Electronic devices such as cellular telephones, computers, and media players often include displays. For example, electronic devices often include backlit displays, such as backlit liquid crystal displays. [0004] Backlit displays typically include a light distributing layer called a light guide plate. The light guide plate is usually formed by injection molding, extruding transparent plastic rectangular sheet or die-cutting from plastic sheet. Light from the array of light emitting diodes can be emitted into the edge of the light guide plate. The light guide plate distributes light over the entire back of the display panel by total internal ref...
