Abstract: A structure for preventing a terminal screen from being damaged during falling comprises a terminal body, and an air channel and a sensor that are disposed in the terminal body. A fan is disposed in the air channel. The sensor is electrically connected to the fan by using a main control chip in the terminal body. The sensor can receive a signal indicating that the terminal body falls to the ground and control the fan to be turned on or turned off by using the main control chip. An air inlet and an air outlet are respectively formed at two ends of the air channel. The air outlet of the air channel is formed on the terminal body. The structure can relieve a force generated when the terminal screen hits the ground during falling.

Abstract: The disclosure provides an internal heat-dissipation terminal, wherein the terminal comprises at least one cavity in which heat-storage material is arranged. The cavity is located in an area without a device in the terminal. The technical solution of the disclosure can be applied to substantially enhance the heat storage capability of the terminal.

Abstract: The present invention relates to a method for time display on a mobile phone. The method includes the following steps: step 1, in a standby state, set a pseudo power off identifier for the mobile phone; step 2, when the mobile phone identifies that the pseudo power off identifier is active, the mobile phone comes into a pseudo power off state; step 3, the mobile phone continually obtains a new time value through a physical layer clock, and displays the new time value on a LCD; and step 4, the mobile phone quits the pseudo power off state, and restarts. The present invention enables the mobile phone to display time without radio frequency signal by setting a third state, i.e., the pseudo power off state.
