Electronic device with auxiliary lighting function and operation method thereof

An electronic device with an auxiliary lighting function, comprising:

• a first body, having a first surface, wherein the first surface comprises a screen area and a border area, and the border area surrounds the screen area;
• a display screen, disposed in the screen area of the first body;
• a light-emitting module, disposed in the border area of the first body;
• and
• a processing module, disposed in the electronic device, and coupled to the display screen and the light-emitting module;
• and
• a light sensing element, coupled to the processing module,
• wherein the processing module activates the light-emitting module in the border area to emit an auxiliary illumination light surrounding the screen area according to whether a required condition is triggered, wherein the required condition comprises:
• determining, by the processing module, whether an ambient light intensity obtained by the light sensing element is greater than a threshold to serve as the required condition of whether to activate the auxiliary illumination light,
• determining, by the processing module, whether the ambient light intensity reaches within a range of a sensing interval to serve as the required condition of whether to activate the auxiliary illumination light,
• wherein the processing module activates the auxiliary illumination light and the display screen displays current lighting intensity information of the light-emitting module when the ambient light intensity does not reach within the range of the sensing interval,
• wherein the processing module turns off the auxiliary illumination light when the ambient light intensity reaches within the range of the sensing interval,
• wherein the processing module determines whether electrical energy of the electronic device is provided by a battery or a power plug,
• wherein when the electrical energy is provided by the power plug in a current power supply status, the processing module adjusts the auxiliary illumination light dynamically based on a distance between a user and the first body, wherein:
• the processing module adjusts a brightness of the auxiliary illumination light to be greater when the distance is relatively long, and
• the processing module adjusts the brightness of the auxiliary illumination light to be less when the distance is relatively short,
• wherein the display screen is a touch display screen,
• wherein brightness of a portion of the light-emitting module extended along a first direction in the border area is correspondingly changed according to adjustment of a first virtual adjustment button displayed on the touch display screen, wherein a position of the first virtual adjustment button is adapted to be correspondingly adjusted in the first direction according to a touch gesture,
• wherein brightness of a portion of the light-emitting module extended along a second direction in the border area is correspondingly changed according to adjustment of a second virtual adjustment button displayed on the touch display screen, wherein a position of the second virtual adjustment button is adapted to be correspondingly adjusted in the second direction according to another touch gesture.
