    • A backlight keyboard (100) includes a plurality of keys (120), a light guide plate (140), and an elastic element (160). Each key includes a key cover (124) and a keypad (122) integrally connected to each other. Further, keypad portions of adjacent keys are integrally connected, as well. The light guide plate is arranged below the keys. The light guide plate defines a plurality of through holes (142), each through hole corresponding to one key. An opaque film (144) is coated on a top surface of the light guide plate. The elastic element is positioned under the light guide plate and is configured for exerting a biasing force on at least one key so as to enable the key to return to its previous position when pressed and released.
    • 背光键盘(100)包括多个键(120),导光板(140)和弹性元件(160)。 每个键包括彼此一体地连接的键盖(124)和键盘(122)。 此外,相邻键的键盘部分也是一体地连接的。 导光板配置在键的下方。 导光板限定多个通孔(142),每个通孔对应于一个键。 在导光板的顶面涂敷不透明膜(144)。 弹性元件位于导光板的下面,并且被构造成在至少一个键上施加偏置力,以便当按压和释放时能够使键返回到其先前的位置。
