Abstract
The utility model brings forward a radiation control circuit of a mobile terminal and a mobile terminal. The radiation control circuit comprises a touch induction plate and a touch induction chip; and the touch induction plate is arranged on a touch screen of the mobile terminal. When the touch induction plate senses that a user approaches or carries out touch operation, the touch induction chip outputs a control signal to reduce the emission power of the terminal. According to the radiation control circuit and the mobile terminal, the touch induction plate and the touch induction chip are arranged to sense the touching or approaching of the user. When the touch induction plate senses that a user approaches or carries out touch operation, the emission power is automatically reduced, thereby reducing the damage on the human body and thus protecting the health of the human body. And the energy conservation and environmental protection are realized beneficially.
