The electronic device can be a full-screen, that is, the whole display surface of the electronic device is a display area, so that the electronic device can display pictures, and the front end of the screen is not provided with a hole of the light sensor. Wherein, this electronic equipment is including the light sense sensor that is used for detecting the luminous intensity, and this light sense sensor can set up in the below of the display area of screen, because the display screen forms for adopting the glass substrate preparation, consequently ambient light can pass display panel and penetrate to light sense sensor department to make the light sense sensor can gather ambient light, and then can detect ambient light intensity.

As will be described in detail below.
Referring to fig. 2, fig. 2 is a schematic flow chart of a method for detecting ambient light intensity according to an embodiment of the present disclosure. As shown in the figure, the ambient light intensity detection method may specifically include the following steps:
201. when the electronic equipment displays the first picture frame with the first screen luminous intensity, the first detected light intensity detected by the light sensor is obtained, and the light sensor is located below the display area of the screen of the electronic equipment.
The light sensor is, for example, an ambient light sensor, and may be implemented by a device such as a phototransistor, a photoresistor, or a photodiode.
In the embodiment of the present application, the display screen of the electronic device may be, for example, an OLED display screen, or may also be a liquid crystal display screen, which is not limited to this. The light sensor is disposed below the display area of the screen, that is, the position of the light sensor corresponds to the display area of the screen, and may be disposed on a glass substrate of the display screen, or may be disposed on the back side of the display screen. Ambient light is incident from the display surface of display screen, because the display screen adopts the glass substrate to make, therefore ambient light can pass the display screen and incide to the position at light sense sensor place to ambient light can be gathered to the light sense sensor.
The screen luminous intensity refers to the brightness of a screen of the electronic device, that is, the intensity of light generated by a light source of the screen of the electronic device. In this embodiment, it is assumed that the brightness of the screen when the electronic device displays the first frame is the first screen luminous intensity, and the first detected light intensity detected by the light sensor is the sum of the ambient light intensity and the brightness of the screen, that is, the sum of the ambient light intensity and the first screen luminous intensity, where the ambient light intensity and the first screen luminous intensity are both unknown numbers.
202. And adjusting the luminous intensity of the first screen according to a preset proportion to obtain the luminous intensity of the second screen.
After the first picture frame is displayed, the luminous intensity of the first screen is adjusted according to a preset proportion, namely, the brightness of the screen is adjusted according to the preset proportion on the basis of the luminous intensity of the first screen. The predetermined ratio is a ratio of the luminous intensity of the first screen, and may be, for example, 5%, 10%, or 20%, and may be specifically selected according to actual needs. Here, the first screen light emission intensity may be increased or decreased by a predetermined ratio, that is, the first screen light emission intensity may be decreased by a predetermined ratio or increased by a predetermined ratio. Taking the predetermined ratio of 10% as an example, the first screen luminous intensity may be reduced by 10%, that is, the first screen luminous intensity is reduced by 10%, and the first screen luminous intensity after the reduction by 10% is the second screen luminous intensity, and if the first screen luminous intensity is set to F1, the second screen luminous intensity is (1-10%) F1, that is, 0.9F 1.
203. And when the electronic equipment displays the second picture frame with the second screen luminous intensity, acquiring second detected light intensity detected by the light sensor.
After the first screen luminous intensity is adjusted to obtain a second screen luminous intensity, the electronic equipment displays a second picture frame according to the second screen luminous intensity, and at the moment, the second detected light intensity detected by the light sensor is the sum of the ambient light intensity and the second screen luminous intensity.
204. The ambient light intensity is calculated from the first detected light intensity, the second detected light intensity, and a predetermined ratio.

In one embodiment, in order to improve the detection accuracy, the first frame and the second frame are consecutive frames, that is, the first frame and the second frame are two adjacent frames, and the second frame is displayed immediately after the first frame is displayed. Therefore, the interval time between the first picture frame and the second picture frame is small, which is generally less than 20ms, and thus the intensity of the ambient light when the first picture frame is displayed and the intensity of the ambient light when the second picture frame is displayed can be regarded as the same.
In this embodiment, the ambient light intensity is calculated according to the following formula:
T1＝E+F1
T2＝E+(1-k)*F1
where T1 denotes the first detected light intensity, T2 denotes the second detected light intensity, E denotes the ambient light intensity, F1 denotes the first screen lighting intensity, and k is a predetermined ratio. T1 and T2 are the detection data of the light sensor, and the predetermined ratio k can be set according to the actual requirement, so the value of the ambient light intensity E can be obtained by solving the above equation system, and the ambient light intensity E can be calculated. For example, taking k as 10%, substituting the above equation results in the following equation set:
T1＝E+F1
T2＝E+(1-10％)*F1＝E+0.9F1
solving the equation system to obtain E-10T 2-9T 1.
The obtained ambient light intensity E is free from the influence of the screen brightness, is relatively consistent with the actual ambient light intensity, and can be used as the actual ambient light intensity.
Through the embodiment, when the electronic equipment displays the first picture frame by the first screen luminous intensity, the first detected light intensity detected by the light sensation sensor is obtained, then the first screen luminous intensity is adjusted according to the preset proportion to obtain the second screen luminous intensity, so that when the electronic equipment displays the second picture by the second screen luminous intensity, the second detected light intensity detected by the light sensation sensor is obtained, and then the ambient light intensity is calculated according to the first detected light intensity, the second detected light intensity and the preset proportion, therefore, the ambient light intensity can be detected when the light sensation sensor is arranged below the display area, holes for the light sensation sensor to receive ambient light do not need to be arranged at the front end of the screen, namely, the hole design of the light sensation sensor does not need to be arranged at the front end of the screen, the comprehensive screen design of the electronic equipment is facilitated, and the screen is more beautiful, the display effect is better, and the accuracy of the ambient light intensity detection can be improved.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an ambient light intensity detecting apparatus according to an embodiment of the present disclosure. The detection device can be integrated in electronic equipment such as a smart phone, a tablet computer or a notebook computer.

The adjusting module 302 is configured to adjust the first screen light-emitting intensity according to a predetermined ratio to obtain a second screen light-emitting intensity. After the first picture frame is displayed, the luminous intensity of the first screen is adjusted according to a preset proportion, namely, the brightness of the screen is adjusted according to the preset proportion on the basis of the luminous intensity of the first screen. Here, the first screen light emission intensity may be increased or decreased by a predetermined ratio, that is, the first screen light emission intensity may be decreased by a predetermined ratio or increased by a predetermined ratio.
The second obtaining module 303 is configured to obtain a second detected light intensity detected by the light sensor when the electronic device displays a second image frame with a second screen light-emitting intensity. After the first screen luminous intensity is adjusted to obtain a second screen luminous intensity, the electronic equipment displays a second picture frame according to the second screen luminous intensity, and at the moment, the second detected light intensity detected by the light sensor is the sum of the ambient light intensity and the second screen luminous intensity.
The calculation module 304 is configured to calculate the ambient light intensity according to the first detected light intensity, the second detected light intensity, and a predetermined ratio. In this embodiment, the ambient light intensity when the electronic device displays the first screen frame and the ambient light intensity when the electronic device displays the second screen frame may be considered to be the same. In one embodiment, in order to improve the detection accuracy, the first frame and the second frame are consecutive frames, that is, the first frame and the second frame are two adjacent frames, and the second frame is displayed immediately after the first frame is displayed. Therefore, the interval time between the first picture frame and the second picture frame is small, which is generally less than 20ms, and thus the intensity of the ambient light when the first picture frame is displayed and the intensity of the ambient light when the second picture frame is displayed can be regarded as the same.
In this embodiment, the calculating module 304 is specifically configured to calculate the ambient light intensity according to the following formula:
T1＝E+F1
T2＝E+(1-k)*F1
where T1 denotes the first detected light intensity, T2 denotes the second detected light intensity, E denotes the ambient light intensity, F1 denotes the first screen lighting intensity, and k is a predetermined ratio. T1 and T2 are the detection data of the light sensor, and the predetermined ratio k can be set according to the actual requirement, so the value of the ambient light intensity E can be obtained by solving the above equation system, and the ambient light intensity E can be calculated. For example, taking k as 10%, substituting the above equation results in the following equation set:
T1＝E+F1
T2＝E+(1-10％)*F1＝E+0.9F1
solving the equation system to obtain E-10T 2-9T 1.
The obtained ambient light intensity E is free from the influence of the screen brightness, is relatively consistent with the actual ambient light intensity, and can be used as the actual ambient light intensity.
Through the embodiment, when the electronic equipment displays the first picture frame by the first screen luminous intensity, the first detected light intensity detected by the light sensation sensor is obtained, then the first screen luminous intensity is adjusted according to the preset proportion to obtain the second screen luminous intensity, so that when the electronic equipment displays the second picture by the second screen luminous intensity, the second detected light intensity detected by the light sensation sensor is obtained, and then the ambient light intensity is calculated according to the first detected light intensity, the second detected light intensity and the preset proportion, therefore, the ambient light intensity can be detected when the light sensation sensor is arranged below the display area, holes for the light sensation sensor to receive ambient light do not need to be arranged at the front end of the screen, namely, the hole design of the light sensation sensor does not need to be arranged at the front end of the screen, the comprehensive screen design of the electronic equipment is facilitated, and the screen is more beautiful, the display effect is better, and the accuracy of the ambient light intensity detection can be improved.
