Abstract

An opening on the surface of shell is connected to an accommodation space. The touch-controlled faceplate composed of a film and a glass basal body is setup in the said accommodation space. The film and the glass basal body are jointed at their corresponding periphery, forming a proper interlayer. The film is exposed at the opening of the shell. The bonding layer located between the shell and the film at proper interval to the periphery of the opening bonds the shell and the film. Deformation can be generated at the position of the opening periphery near the film. Thus, it is guaranteed that the film and the corresponding basal body can be contacted each other.
