Wherein, the display area is used to display information such as images and texts. No information is displayed in the non-display area. The non-display area can be used to set some functional components, such as camera, fingerprint identification module and other functional components.

In some embodiments, the display screen 20 may display full screen. That is, the display screen 20 only includes a display area, not a non-display area.

In some embodiments, the display screen 20 may be a liquid crystal display (Liquid Crystal Display, LCD) or an organic light-emitting diode display (Organic Light-Emitting Diode, OLED).

The circuit board 30 is installed inside the housing 40 . The circuit board 30 may be a main board of the electronic device 100 . Functional components such as a camera and a processor may be integrated on the circuit board 30 . Meanwhile, the display screen 20 may be electrically connected to the circuit board 30 .

In some embodiments, a display control circuit is disposed on the circuit board 30 . The display control circuit outputs electrical signals to the display screen 20 to control the display screen 20 to display information.

The casing 40 is used to form the outer contour of the electronic device 100 . The material of the housing 40 can be plastic or metal. The housing 40 can be integrally formed.

In one embodiment, a method for detecting ambient light intensity is provided, and the method for detecting ambient light intensity can be applied to electronic equipment. The electronic device may include smart phones, tablet computers and other devices. As shown in Figure 2, the ambient light intensity detection method may include the following processes:

101. Acquire an ambient light intensity detection value.

Wherein, the electronic device is provided with an ambient light sensor. The ambient light sensor is located under the display of the electronic device. Ambient light enters the ambient light sensor through the display screen. Therefore, the ambient light sensor can detect the ambient light intensity through the display screen. The electronic device can acquire the ambient light intensity detection value detected by the ambient light sensor.

It should be noted that since ambient light is visible light, the ambient light sensor detects the intensity of visible light. The display itself can emit light, and the light emitted by the display is also visible light. Therefore, the light emitted by the display screen will affect the detection data of the ambient light sensor, so that the ambient light intensity detected by the ambient light sensor is larger than the actual ambient light intensity. Therefore, the detected ambient light intensity value acquired by the electronic device is not the actual ambient light intensity value.

102. Determine RGB spectrum information of the detected light.

In a specific implementation process, a color sensor (color sensor) can be installed inside the electronic device, and the RGB spectrum information of the detected light can be identified through the color sensing function of the color sensor.

103. Acquire the target light intensity value of the target light whose RGB spectrum information matches the sample RGB spectrum information, where the sample RGB spectrum information is the RGB spectrum information of the display screen.

No matter what kind of light source the display is, it is composed of the mixture of RGB three primary colors, but the ratio of the three primary colors is different. Therefore, after determining the RGB spectral information of the detected light, the electronic device can compare the determined RGB spectral information with the sample RGB spectral information, determine the target light from the detected light, and obtain the target light The light intensity value of the RGB three primary colors as the target light intensity value.

In some embodiments, a color sensor matching the RGB spectrum information of the display screen can be installed inside the electronic device, and then the color sensor can be used to measure RGB light intensity values. Suppose the spectral wavelength range of R of the display screen is 615+/-2.5nm, the spectral wavelength range of G is 535+/-2.5nm, and the spectral wavelength range of B is 465+/-2.5nm, then the installed colorsensor can only Detects light in the wavelength range of the spectrum shown, while other wavelengths are not detected, such as 550nm.

104. Adjust the ambient light intensity detection value according to the target light intensity value to obtain the ambient light intensity value.

Wherein, after the electronic device acquires the target light intensity value, the detected value of the ambient light intensity may be adjusted according to the target light intensity value to obtain the ambient light intensity value. After the electronic device adjusts the ambient light intensity detection value, it can reduce or even eliminate the influence of the light emitted by the display screen on the final ambient light intensity value, so that the final ambient light intensity value is different from the actual ambient light intensity value. match. Therefore, when the electronic device adjusts the brightness of the display screen according to the ambient light intensity value, the brightness of the display screen can be adjusted more accurately, so that the brightness of the display screen can better adapt to the surrounding environment. For example, as shown in FIG. 3 , after the electronic device obtains the ambient light intensity value, it adjusts the brightness of the display screen according to the actual situation, so as to reduce (or increase) the brightness of the display screen.

As can be seen from the above, the ambient light intensity detection method provided by the embodiment of the present application obtains the detection value of the ambient light intensity, then determines the RGB spectral information of the detected light, and then obtains the target light whose RGB spectral information matches the sample RGB spectral information. The target light intensity value, wherein the sample RGB spectrum information is the RGB spectrum information of the display screen, and the ambient light intensity detection value is adjusted according to the target light intensity value to obtain the ambient light intensity value. In this solution, the electronic device can obtain corresponding data according to the RGB spectrum information of the display screen to adjust the detection value of the ambient light sensor, thereby reducing the influence of the light generated by the display screen information on the detection of ambient light intensity by the electronic device , to improve the accuracy of detecting ambient light intensity.

In some embodiments, another method for detecting ambient light intensity is provided, which is applied to electronic equipment. The electronic device may include smart phones, tablet computers and other devices. As shown in Figure 4, the ambient light intensity detection method may include the following processes:

201. Acquire an ambient light intensity detection value.

Wherein, the electronic device is provided with an ambient light sensor. The ambient light sensor is located under the display of the electronic device. Ambient light enters the ambient light sensor through the display screen. Therefore, the ambient light sensor can detect the ambient light intensity through the display screen. The electronic device can acquire the ambient light intensity detection value detected by the ambient light sensor.

It should be noted that since ambient light is visible light, the ambient light sensor detects the intensity of visible light. The display itself can emit light, and the light emitted by the display is also visible light. Therefore, the light emitted by the display screen will affect the detection data of the ambient light sensor, so that the ambient light intensity detected by the ambient light sensor is larger than the actual ambient light intensity. Therefore, the detected ambient light intensity value acquired by the electronic device is not the actual ambient light intensity value.

202. Determine RGB spectrum information of the detected light, where the RGB spectrum information includes RGB frequency values.

In the specific implementation process, the colorsensor can be installed inside the electronic device, and the RGB spectrum information of the detected light can be identified through the color sensing function of the colorsensor, such as the frequency and wavelength of the detected light.

203. Acquire RGB spectrum information of the display screen, where the sample RGB spectrum information includes a sample RGB frequency range.

No matter what kind of light source the display is, it is composed of the mixture of RGB three primary colors, but the ratio of the three primary colors is different. In general, the RGB spectrum information of the display screen is fixed, and it can emit RGB light at a specific frequency or wavelength. For example, the spectrum wavelength range of R of the display screen can be 615+/-2.5nm, and the spectrum of G The wavelength range can be 535+/-2.5nm, the spectral wavelength range of B can be 465+/-2.5nm, etc.

In nature, the spectrum information of visible light can refer to Table 1:

Table 1

name wavelength(nm) Frequency (MHZ) purple light 400～435 680～790 blu ray 450～480 620～680 blue light 480～490 600～620 green light 500～560 530～600 yellow light 580～595 510～520 orange light 595～605 480～510 red light 605～700 405～480

Therefore, a color sensor matching the RGB spectrum information of the display screen can be installed inside the electronic device, and then the color sensor can be used to measure the RGB light intensity value of the detected light.

204. Determine whether the RGB frequency value is within the sample RGB frequency range; if yes, perform step 205, if not, end the process.

Specifically, the acquired RGB frequency value is compared with the sample RGB frequency interval of the display screen to determine whether the RGB frequency value is within the sample RGB frequency interval.

205. Acquire the light intensity value of the target light corresponding to the RGB frequency value, so as to obtain the target light intensity value.

Suppose there are sample RGB frequency intervals: R[412.5, 417.5], G[562.5, 567.5], B[632.5, 637.5], the unit is MHZ. Then, the light intensity of the detected light whose frequency is in any frequency range of RGB can be acquired, and the acquired light intensity can be superimposed to obtain the target light intensity value.

206. Adjust the ambient light intensity detection value based on the target light intensity value to obtain an ambient light intensity value.

In the embodiment of the present application, there may be multiple ways of adjusting the detection value of the ambient light intensity based on the target light intensity value. for example:

In some embodiments, the step of "adjusting the detected value of ambient light intensity based on the target light intensity value to obtain the value of ambient light intensity" may include the following process:

Calculate the difference between the ambient light intensity detection value and the target light intensity value;

Determine the ambient light intensity value based on the difference.

In some implementation manners, the difference may be directly used as the ambient light intensity value.

In practical applications, since the ambient light may also have the same RGB light as the spectrum information of the display screen, it will also be sensed by the color sensor that only receives the RGB light source of the display screen. Therefore, directly using the above difference as the final ambient light intensity will result in a smaller value than the actual ambient light intensity. Therefore, in some embodiments, the step "determine the ambient light intensity value according to the difference" may include the following process:

Acquiring a preset first adjustment coefficient;

According to the first adjustment coefficient and the difference value, an ambient light intensity value is obtained through calculation.

In practical applications, RGB with the same frequency spectrum of the display screen generally accounts for a certain proportion of the entire ambient light, which is a fixed value, which can be set at about 5%. Assuming that the difference is S and the first adjustment coefficient is X, the calculation formula for the ambient light intensity value may be: S*(1+X).

In some embodiments, the step of "adjusting the detected value of ambient light intensity based on the target light intensity value to obtain the value of ambient light intensity" may include the following process:

Obtain a preset second adjustment coefficient;

calculating the product of the second adjustment coefficient and the target light intensity value to obtain the light intensity adjustment value;

The ambient light intensity detection value is adjusted according to the light intensity adjustment value to obtain the ambient light intensity value.

Similarly, since the ambient light intensity detection value includes the light intensity value of the luminous line of the display screen, and the target light intensity value detected by the colorsensor may include the light intensity value of part of the ambient light in the external ambient light, therefore, The detected target light intensity value needs to be optimized to obtain a more accurate ambient light intensity adjustment value.

Specifically, assuming that the ambient light intensity detection value is D, the second adjustment coefficient is Y, and the target light intensity value is Z, the calculation formula for the ambient light intensity value may be: D-(Y*Z). Wherein, the value of Y depends on the ratio of Z to D.

During specific implementation, the present application is not limited by the execution order of the described steps, and some steps may be performed in other orders or simultaneously in the case of no conflict.

As can be seen from the above, the ambient light intensity detection method provided by the embodiment of the present application obtains the detection value of the ambient light intensity, then determines the RGB spectral information of the detected light, and then obtains the target light whose RGB spectral information matches the sample RGB spectral information. The target light intensity value, wherein the sample RGB spectrum information is the RGB spectrum information of the display screen, and the ambient light intensity detection value is adjusted according to the target light intensity value to obtain the ambient light intensity value. In this solution, the electronic device can obtain corresponding data according to the RGB spectrum information of the display screen to adjust the detection value of the ambient light sensor, thereby reducing the influence of the light generated by the display screen information on the detection of ambient light intensity by the electronic device , to improve the accuracy of detecting ambient light intensity.
