The invention relates to a method for controlling dispersed switching-on and switching-off of touch screen background lamps, and a mobile terminal, wherein the method comprises the steps of when the touch screen enters a game control interface, making the touch screen automatically enter a background lamp control interface; receiving a pressing operation which is performed by a user on the background lamp control interface, and determining whether a pressing position is at a random switch in the N sub-switches; if yes, identifying a lamp tube which corresponds with the pressed sub-switch, and transmitting a control instruction for switching off the lamp tube to a switch controller; generating a high-level voltage by the switch controller and inputting to an MOSEFT switching circuit which corresponds with the lamp tube; and switching off the lamp tube by the MOSFET switching circuit. The method and the mobile terminal according to the invention have advantages of effectively settling a problem of high electric power consumption of the mobile terminal touch screen when the mobile terminal touch screen is used as a handle, simplifying an operation process when the mobile terminal is used as the handle, more conveniently switching the on-state and the off-state of the background lamps, and improving user experience.
