1. A brightness control method, adapted for a display of an electronic device, the electronic device comprising a chip and an embedded controller, the brightness control method comprising:
detecting an environmental condition of the electronic device; determining whether the environmental condition of the electronic device matches a preset condition; causing the electronic device to enter a special brightness adjustment mode when the environmental condition matches the preset condition, and causing the electronic device to enter a general mode when the environmental condition does not match the preset condition; and executing the following steps when the environmental condition does not match the preset condition:
detecting whether a special brightness adjustment event occurs;causing the electronic device to enter the special brightness adjustment mode if the special brightness adjustment event occurs; andcausing the electronic device to enter the general mode if the special brightness adjustment event does not occur, wherein the step of detecting whether the special brightness adjustment event occurs comprises detecting whether a special brightness adjustment command is received to adjust the brightness of the display to be higher than a first threshold brightness or lower than a second threshold brightness, wherein the first threshold brightness is greater than the second threshold brightness; wherein a brightness of the display is controlled by the embedded controller independently of the chip in the special brightness adjustment mode, and the brightness of the display is controlled by the chip independently of the embedded controller in the general mode.
