Abstract

The invention discloses a control method and electronic equipment. The control method comprises the steps as follows: a voltage value of a power supply for supplying electricity to a light-emitting component is detected; the voltage value is used for reflecting the electric quantity of the power supply; a control signal is generated according to the voltage value; and a resistor of a control circuit of the light-emitting component is connected by responding to the control signal, so that a current value when the power supply supplies electricity to the light-emitting component is controlled through the control circuit according to the connected resistor.

Description

technical field [0001] The invention relates to control technology, in particular to a control method and electronic equipment. Background technique [0002] At present, the display screens of electronic devices such as mobile phones mostly use liquid crystal (LCD, Liquid Crystal Display) display screens. Along with the needs of users, the size of the LCD display screen is continuously increasing, and the LCD backlight current is also getting higher and higher. When the battery power of an electronic device is very low, a large load current will cause the electronic device to suddenly power down and shut down; if the battery is over-discharged, it will be difficult to start the electronic device immediately after plugging in the charger. Excessively large and shuts down quickly. [0003] The existing solution is to limit the brightness of the LCD display through software to reduce the load current. This solution can only be implemented after the software is started. When...
