  • Portable terminal having transparent cover member
    Patent number: 8132941
    Abstract: Disclosed is a portable terminal having a transparent member at an outside thereof, including a terminal body having at least one light emitting member, and a transparent cover member partially forming an outer appearance of the terminal body and transmitting light from the light emitting members to the outside. The transparent cover member includes a light diffusion pattern portion for scattering light from the light emitting members so as to minimize an occurrence of a case in which a specific position where the light emitting member is formed is brightly illuminated but other position is dimmed.
    Type: Grant
