Method of automatic power down protection during contact of terminal mobile with liquid and terminal mobile

ActiveCN103366138AGood protectionReduce production and processing costsInternal/peripheral component protectionBurning outCapacitance
The invention discloses a method of automatic power down protection during contact of a terminal mobile with liquid. The method is applicable to the terminal mobile with a capacitive touch screen, and comprises the following steps that (1) whether capacitance variation values of zones on a touch screen are in a preset range is detected; the preset range is a range of the capacitance variation values the touch screen generated during the contact between the liquid and the touch screen; and a zone with the capacitance variation value in the preset range is called a liquid contact zone; (2) a total area value of the liquid contact zone is calculated; and whether the total area value is greater than or equal to a preset value is judged, if so, then the next step is executed, if not, an initial state is returned; and (3) the terminal mobile is powered down and turned off. According to the method, automatic power down of the terminal mobile can be triggered by the terminal mobile when the liquid contact zone on the touch screen is greater than or equal to a used area of the touch screen; the danger that the terminal mobile is burned-out since the liquid enters the terminal mobile is avoided; and the terminal mobile is well protected.
