    • 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.
    • 电子设备可以设置有显示器。 背光结构可以用于为显示器提供背光。 背光结构可以包括导光板。 矩形环形底盘可以具有容纳导光板的矩形开口。 底座的一个或多个边缘可以设置有接收发光二极管或其他光源的凹槽阵列。 光源可以将光发射到导光板的边缘部分中。 底架可以包括第一塑料结构,例如由诸如白色塑料之类的材料形成的光反射结构。 第一塑料结构可以围绕导光板的两个或更多个周边边缘。 底座还可以包括第二塑料结构,诸如由诸如黑色塑料的材料形成的阻光结构,其帮助防止光泄漏。
