    • Provided are a light-emitting keypad and a method of fabricating the light-emitting keypad. The light-emitting keypad includes: a light guide film; a reflective layer formed on a rear surface of the light guide film; a first adhesive layer formed on a rear surface of the reflective layer; and a substrate located under the first adhesive layer and having a dome, wherein the first adhesive layer is located in a region corresponding to the dome. Another light-emitting keypad includes: a light guide film; a first adhesive layer and a reflective layer that are formed on a rear surface of the light guide film; and a substrate located under the first adhesive layer and the reflective layer and having a dome, wherein the first adhesive layer is located in a region corresponding to the dome, and the reflective layer is located in a region other then the region corresponding to the dome. Thus, the dome can be fixed without use of a separate sheet for fixing the dome, resulting in a thinner light-emitting keypad.
    • 提供了发光键盘和制造发光键盘的方法。 发光键盘包括:导光膜; 形成在所述导光膜的后表面上的反射层; 形成在所述反射层的后表面上的第一粘合剂层; 以及位于所述第一粘合剂层下方并具有圆顶的基板,其中所述第一粘合剂层位于对应于所述圆顶的区域中。 另一个发光键盘包括:导光膜; 形成在导光膜的后表面上的第一粘合剂层和反射层; 以及位于所述第一粘合剂层和所述反射层下方并具有圆顶的基板,其中所述第一粘合剂层位于与所述圆顶对应的区域中,并且所述反射层位于除了所述圆顶之外的区域之外的区域中 。 因此,圆顶可以固定而不使用用于固定圆顶的单独的片,导致更薄的发光键盘。
