Embodiment 1

[0062] Please refer to figure 1 , which shows a schematic structural diagram of the screen illuminating assembly provided by Embodiment 1 of the present invention. The screen illuminating assembly can be used in electronic equipment. The electronic device may be a smartphone, tablet, e-reader, or the like. The screen illuminating component may include: a chromaticity sensor 110 , a controller 120 electrically connected to the chromaticity sensor 110 , and a light emitting device 130 electrically connected to the controller 120 .

[0063] Chromaticity sensor 110, used to collect the chromaticity value of external ambient light;

[0064] The controller 120 is configured to acquire the chromaticity value of the ambient light collected by the chromaticity sensor 110; output a control signal to the light emitting device according to the chromaticity value 110;

[0065] The light emitting device 130 is configured to output auxiliary light to the display screen according to the co...

Embodiment 2

[0068] Please refer to figure 2 , which shows a schematic structural diagram of the screen illuminating assembly provided by Embodiment 2 of the present invention. The screen illuminating assembly can be used in electronic equipment. The electronic device may be a smartphone, tablet, e-reader, or the like. The screen illumination component may include: a chromaticity sensor 210 , a controller 220 electrically connected to the chromaticity sensor 210 , and a light emitting device 230 electrically connected to the controller 220 .

[0069] The chromaticity sensor 210 is used to collect the chromaticity value of the ambient light; the chromaticity value is a color temperature value or a color coordinate value. The chromaticity sensor is generally located above the screen of the electronic device, and can receive light from the environment where the electronic device is located, and try to avoid receiving light from inside the electronic device. The chromaticity sensor can be ...

Embodiment 3

[0079] Please refer to image 3 , which shows a method flowchart of the control method provided by Embodiment 3 of the present invention. This control method is used in a controller of an electronic device including the screen illuminating component as shown in the first embodiment above, and the control method includes:

[0080] Step 301, acquiring the chromaticity value of the ambient light collected by the chromaticity sensor;

[0081] The controller acquires the chromaticity value of the ambient light collected by the chromaticity sensor.

[0082] Step 302, outputting a control signal to the light-emitting device according to the chromaticity value, so that the light-emitting device outputs auxiliary light to the display screen according to the control signal, and the chromaticity value of the auxiliary light corresponds to the chromaticity value of the external ambient light;

[0083] The controller outputs a control signal to the light-emitting device according to the ...

Abstract

The invention discloses a screen illuminating component, which belongs to the field of electronic technology. The components include a chromaticity sensor, a controller electrically connected to the chromaticity sensor, and a light emitting device electrically connected to the controller; the chromaticity sensor is used to collect the chromaticity value of the external ambient light; the controller is used to obtain the The chromaticity value of the external ambient light collected by the chromaticity sensor; outputting a control signal to the light-emitting device according to the chromaticity value; the light-emitting device is used to output auxiliary light to the display screen according to the control signal. The invention collects the chromaticity value of the external ambient light through the chromaticity sensor, and controls the light-emitting device to output light corresponding to the chromaticity value of the external ambient light; The chromaticity of the external ambient light is different, which may cause damage to the user's eye health; the auxiliary light that has the same output chromaticity value and the chromaticity value of the external ambient light can avoid causing eye health problems to the user. Effect.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a screen illuminating component, electronic equipment and a control method for the screen illuminating component. Background technique [0002] At present, most electronic devices have display screens. In order to make the display screens in electronic devices usable under various light conditions, a built-in light source is generally built into the electronic device, so that the built-in light source can be turned on when the external light is insufficient to make the Use of the display is not affected. The "electronic device" mentioned here can be any one of smart phone, tablet computer and e-reader. [0003] E-paper (electronic paper) is an electronic device with reflective display characteristics, and its display characteristics will change with changes in external ambient light. In the case of dark ambient light, the electronic device can also be used normally by turni...
