Abstract

An electronic device with an auxiliary illumination function and an operation method thereof are provided. The electronic device includes a first body, a display screen, a light-emitting module, and a processing module. The first body has a first surface. The first surface includes a screen area and a border area, and the border area surrounds the screen area. The display screen is disposed in the screen area of the first body. The light-emitting module is disposed in the border area of the first body. The processing module is disposed in the electronic device and is coupled to the display screen and the light-emitting module. The processing module activates the light-emitting module in the border area to emit an auxiliary illumination light according to a required condition.

First claim

What is claimed is:

1 . 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.

2 . The electronic device as described in claim 1 , wherein the light-emitting module comprises:
a screen border, disposed on the first surface of the first body, wherein the screen border is of a semi-transparent material, or the screen border is of a transparent material and is coated with a semi-transparent coating material; and a light-emitting unit, located behind the screen border and embedded in the first body.

3 . The electronic device as described in claim 2 , wherein the light-emitting module is a direct-type light-emitting module, a first side of the light-emitting unit emits the auxiliary illumination light toward the screen border, and a second side of the light-emitting unit is provided with a light shielding element, wherein the first side is opposite to the second side.

4 . The electronic device as described in claim 2 , wherein the light-emitting module is a reflective-type light-emitting module, the light-emitting unit is disposed on an inner side top portion of the first body, and emits the auxiliary illumination light toward a light-reflective element, such that the auxiliary illumination is reflected by the light-reflective element to the screen border.

5 . The electronic device as described in claim 2 , wherein the light-emitting module comprises a direct-type light-emitting module and a reflective-type light-emitting module, at least one portion of the border area is provided with the direct-type light-emitting module, and at least another portion of the border area is provided with the reflective-type light-emitting module.

6 . The electronic device as described in claim 1 , wherein the light-emitting module further comprises:
a light guide bar, disposed along the border area; and a control panel, coupled to two ends of the light guide bar, wherein a first light-emitting unit and a second light-emitting unit disposed on the control panel respectively emit light toward the two ends of the light guide bar.

7 . The electronic device as described in claim 1 , wherein the light-emitting module further comprises:
a metal conductor, disposed along the border area, and disposed on an inner side of the screen border; a conductive wire, coupled to the metal conductor; and a control panel, coupled to the conductive wire, wherein the light-emitting unit is a nano light-emitting coating material and is coated on an outer side or an inner side of the screen border, wherein the control panel provides electrical energy through the conductive wire and the metal conductor to the nano light-emitting coating material.

8 . The electronic device as described in claim 1 , wherein the processing module is configured to drive the display screen to display an adjustment interface, and takes a setting result corresponding to the adjustment interface as the required condition for activating the auxiliary illumination light.

9 . The electronic device as described in claim 1 , further comprising:
a second body, having one side pivotally connected to one side of the first body, and comprising a switch unit, wherein the switch unit is coupled to the processing module and configured to provide an enable signal, and the enable signal is taken as the required condition for activating the auxiliary illumination light.

10 . The electronic device as described in claim 1 , further comprising:
a second body, having one side pivotally connected to one side of the first body, and comprising at least two adjustment units, wherein the at least two adjustment units are coupled to the processing module, and configured to provide at least two adjustment signals, wherein the processing module adjusts brightness of the auxiliary illumination light provided by the light-emitting module according to the at least two adjustment signals.

11 . The electronic device as described in claim 1 , further comprising:
a battery control unit, coupled to the processing module, the display screen, and the light-emitting module, wherein the processing module dynamically adjusts an auxiliary illumination light provided by the light-emitting module according to battery charge information provided by the battery control unit.
