Abstract

A mobile terminal keyboard comprises a keyboard body and a key, where sidewalls of the key can produce a cavity so as to form a capsule structure. The keyboard body and the sidewalls can be made of a transparent material; and transparent liquid can be included in the cavity. The mobile terminal keyboard can be convenient for a user and humanized. Light can pass through the transparent liquid in the cavity from one or more directions and generate refraction to form a colorful effect. The liquid in the cavity also can be deformed to generate various color changes on the press of a key.
