Abstract:
1. A mobile terminal comprising: a main body; a receiver portion; a data display and a keypad formed on an upper surface of said main body; a flip cover for covering or exposing said keypad; a battery attached to a lower surface of said main body; a solar cell attached to an outer surface of said flip cover so as to be exposed to an external environment for generating a voltage when light is received; a connection element electrically connecting said solar cell to said main body; a comparator for comparing the voltage generated by said solar cell with a predetermined voltage; a voltage booster circuit for boosting said voltage generated by said solar cell; and a semiconductor relay coupled to said voltage booster circuit and to said comparator, said semiconductor relay, in response to said voltage generated by said solar cell being greater than the predetermined voltage, for rendering said solar cell so as not to supply electricity to said battery and simultaneously rendering said solar cell to supply the boosted voltage from said voltage booster circuit to said main body for signal reception standby.
