Abstract

The embodiment of the invention provides a backlight control method for input equipment, and a mobile terminal. The method comprises the following steps that: the mobile terminal acquires a first input signal through first input equipment; the mobile terminal detects the state of the backlight of second input equipment, wherein the state of the backlight of the second input equipment comprises an opening state and a closing state, and the second input equipment is arranged on the mobile terminal in a hardware mode; and if detecting that the state of the backlight of the second input equipment is the opening state, the mobile terminal closes the backlight of the second input equipment. By the embodiment of the invention, the electric quantity of the mobile terminal is saved, and the efficiency of the backlight of the second input equipment is improved.

Description

technical field [0001] Embodiments of the present invention relate to control technologies, and in particular to a backlight control method of an input device and a mobile terminal. Background technique [0002] Generally speaking, a mobile terminal can acquire information input by a user using the mobile terminal through an input device provided by itself. In order to facilitate the user of the mobile terminal to input information, when the user inputs information through the input device, the backlight of the input device is turned on; when the user stops inputting information through the input device for a preset standby time, the backlight of the input device is turned off . [0003] However, during the standby time, even when the user inputs information through other input devices, the backlight of the input device is always on, thereby wasting the power of the mobile terminal and reducing the efficiency of the backlight of the input device.
