Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 100 includes a cover plate 10, a display 20, a circuit board 30, a housing 40, and an ambient light sensor 50 mounted inside the housing 40.
The cover plate 10 is mounted to the display screen 20 to cover the display screen 20. The cover plate 10 may be a transparent glass cover plate. In some embodiments, the cover plate 10 may be a glass cover plate made of a material such as sapphire.
The display screen 20 is mounted on the housing 40 to form a display surface of the electronic device 100. In some embodiments, the display screen 20 includes a display area and a non-display area. The display area is used for displaying information such as images and texts. The non-display area does not display information. The non-display area can be used for setting some functional components, such as functional components of a camera, a fingerprint identification module and the like.
In some embodiments, the display screen 20 may be displayed full screen. That is, the display screen 20 includes only display regions and does not include non-display regions.
In some embodiments, the Display 20 may be a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED) Display.
The circuit board 30 is mounted inside the housing 40. The circuit board 30 may be a motherboard 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, display control circuitry is disposed on the circuit board 30. The display control circuit outputs an electrical signal to the display screen 20 to control the display screen 20 to display information.
The housing 40 is used to form the outer contour of the electronic device 100. The housing 40 may be made of plastic or metal. The housing 40 may be integrally formed.
An ambient light sensor 50 is mounted inside the housing 40. Meanwhile, the ambient light sensor 50 is electrically connected to the circuit board 30. For example, the ambient light sensor 50 may be integrated on the circuit board 30. The ambient light sensor 50 is used for detecting the intensity of the ambient light, so that the electronic device 100 can adjust the brightness of the display screen 20 according to the intensity of the ambient light detected by the ambient light sensor 50, so that the brightness of the display screen 20 is adapted to the surrounding environment. For example, in a darker environment, the electronic device 100 may reduce the brightness of the display screen 20; in brighter environments, the electronic device 100 may increase the brightness of the display screen 20.
In the embodiment of the present application, the ambient light sensor 50 may be located below the display area of the display screen 20. That is, the orthographic projection of the ambient light sensor 50 on the display screen 20 is located at the display area of the display screen 20. It will be appreciated that the ambient light sensor 50 now collects ambient light from the outside through the display screen 20 to achieve sensing of ambient light intensity. That is, external ambient light enters the ambient light sensor 50 through the display area of the display screen 20.
In one embodiment, an ambient light intensity detection method is provided, which can be applied in an electronic device. The electronic device may include a smart phone, a tablet computer, and the like. As shown in fig. 2, the ambient light intensity detecting method may include the following steps:
101. and acquiring an ambient light intensity detection value.
Wherein, be provided with ambient light sensor in the electronic equipment. The ambient light sensor is located below a display screen of the electronic device. Ambient light enters the ambient light sensor through the display screen. Thus, the ambient light sensor may detect the intensity of ambient light through the display screen. The electronic device may acquire an ambient light intensity detection value detected by the ambient light sensor.
It should be noted that, since the ambient light is visible light, the ambient light sensor detects the intensity of the visible light. The display screen can emit light, and the light emitted by the display screen is also visible light. Therefore, the light emitted from the display screen may affect the detection data of the ambient light sensor, so that the intensity of the ambient light detected by the ambient light sensor is larger than the actual intensity of the ambient light. Therefore, the ambient light intensity detection value acquired by the electronic device is not the actual ambient light intensity value.
102. RGB spectral information of the detected light is determined.
In a specific implementation process, a color sensor (colorsensor) may be installed inside the electronic device, and RGB spectrum information of the detected light may be identified through a color sensing function of the colorsensor.
103. And acquiring a target light intensity value of the target light matched with the RGB spectrum information of the sample, wherein the RGB spectrum information of the sample is the RGB spectrum information of the display screen.
Regardless of the light source of the display screen, the display screen is composed of RGB three primary colors, and the proportions of the three primary colors are different. Therefore, after determining the RGB spectrum information of the detected light, the electronic device may compare the determined RGB spectrum information with the sample RGB spectrum information, determine a target light from the detected light, and obtain the light intensity values of the RGB three primary colors in the target light as the target light intensity value.
In some embodiments, a color sensor matched with the RGB spectrum information of the display screen may be installed inside the electronic device, and then the RGB light intensity value may be measured using the color sensor. Assuming that 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, the colorsensor installed can only detect light of the spectral wavelength range shown, but other wavelengths cannot detect, such as 550 nm.
104. And adjusting the ambient light intensity detection value according to the target light intensity value to obtain an ambient light intensity value.
After the electronic device obtains the target light intensity value, the environmental light intensity detection value can be adjusted according to the target light intensity value to obtain an environmental light intensity value. After the electronic equipment adjusts the ambient light intensity detection value, the influence of light emitted when the display screen displays information on the finally obtained ambient light intensity value can be reduced or even eliminated, so that the finally obtained ambient light intensity value is matched with the actual ambient light intensity. Therefore, when the electronic equipment adjusts the brightness of the display screen according to the ambient light intensity value, the adjustment of the brightness of the display screen can be more accurate, and the brightness of the display screen is better adapted to the ambient environment. For example, as shown in fig. 3, after obtaining the ambient light intensity value, the electronic device adjusts the brightness of the display screen according to the actual situation to decrease (or increase) the brightness of the display screen.
As can be seen from the above, in the ambient light intensity detection method provided in the embodiment of the present application, the ambient light intensity detection value is obtained, then the RGB spectrum information of the detected light is determined, and then the target light intensity value of the target light matched between the RGB spectrum information and the sample RGB spectrum information is obtained, where 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, so as to obtain the ambient light intensity value. In the scheme, the electronic equipment can acquire corresponding data according to the RGB frequency spectrum information of the display screen to adjust the detection value of the ambient light sensor, so that the influence of light generated by the display screen to the intensity of ambient light detected by the electronic equipment is reduced, and the accuracy of the intensity of the ambient light is improved.
In some embodiments, another ambient light intensity detection method is provided and applied to an electronic device. The electronic device may include a smart phone, a tablet computer, and the like. As shown in fig. 4, the ambient light intensity detecting method may include the following steps:
201. and acquiring an ambient light intensity detection value.
Wherein, be provided with ambient light sensor in the electronic equipment. The ambient light sensor is located below a display screen of the electronic device. Ambient light enters the ambient light sensor through the display screen. Thus, the ambient light sensor may detect the intensity of ambient light through the display screen. The electronic device may acquire an ambient light intensity detection value detected by the ambient light sensor.
It should be noted that, since the ambient light is visible light, the ambient light sensor detects the intensity of the visible light. The display screen can emit light, and the light emitted by the display screen is also visible light. Therefore, the light emitted from the display screen may affect the detection data of the ambient light sensor, so that the intensity of the ambient light detected by the ambient light sensor is larger than the actual intensity of the ambient light. Therefore, the ambient light intensity detection value acquired by the electronic device is not the actual ambient light intensity value.
202. RGB spectral information of the detected light is determined, the RGB spectral information including RGB frequency values.
In a specific implementation process, the colorsensor may be installed inside the electronic device, and RGB spectrum information of the detected light, such as frequency and wavelength of the detected light, may be identified through a color sensing function of the colorsensor.
203. And acquiring RGB spectrum information of the display screen, wherein the sample RGB spectrum information comprises a sample RGB frequency interval.
Regardless of the light source of the display screen, the display screen is composed of RGB three primary colors, and the proportions of the three primary colors are different. Typically, the RGB spectral information of the display screen is fixed and can radiate RGB light at a specific frequency or wavelength, for example, R of the display screen may have a spectral wavelength range of 615+/-2.5nm, G of the display screen may have a spectral wavelength range of 535+/-2.5nm, B of the display screen may have a spectral wavelength range of 465+/-2.5nm, etc.
In nature, the spectrum information of visible light can refer to table 1:
TABLE 1
| Name (R) | Wavelength (nm) | Frequency (MHZ) |
| |
400～435 | 680～790 |
| Blue light | 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 matched with the RGB spectrum information of the display screen may be installed inside the electronic device, and then the RGB light intensity values of the detected light may be measured using the color sensor.
204. Judging whether the RGB frequency value is in a sample RGB frequency interval or not; if yes, go to step 205, otherwise, end the process.
Specifically, the obtained RGB frequency value is compared with a sample RGB frequency interval of the display screen, and it is determined whether the RGB frequency value is within the sample RGB frequency interval.
205. And acquiring the light intensity value of the target light corresponding to the RGB frequency value to obtain the target light intensity value.
Assume that there is a sample RGB frequency bin: r [412.5, 417.5], G [562.5, 567.5], B [632.5, 637.5] in MHZ. Then, the light intensity of the detected light with a frequency within any frequency interval of RGB can be obtained, and the obtained light intensities are superimposed to obtain the target light intensity value.
206. And adjusting 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 a plurality of ways to adjust the ambient light intensity detection value based on the target light intensity value. Such as:
in some embodiments, the step of "adjusting the ambient light intensity detection value based on the target light intensity value to obtain the ambient light intensity value" may include the following processes:
calculating the difference value between the ambient light intensity detection value and the target light intensity value;
an ambient light intensity value is determined from the difference.
In some embodiments, the difference may be directly used as the ambient light intensity value.
In practical applications, since the external ambient light may also have RGB light rays having the same spectrum information as the display screen, the external ambient light is also sensed by a color sensor which is dedicated to receive only the RGB light source of the display screen. Therefore, directly using the difference as the finally obtained ambient light intensity results in a smaller value than the actual ambient light intensity value. Thus, in some embodiments, the step of "determining the ambient light intensity value from said difference" may comprise the following procedure:
acquiring a preset first adjusting coefficient;
and calculating to obtain the ambient light intensity value according to the first adjusting coefficient and the difference value.
In practical application, the RGB with the same frequency spectrum of the display screen generally accounts for a certain proportion of the whole ambient light, and is a fixed value, and can be specifically set to be about 5%. Assuming that the difference is S and the first adjustment coefficient is X, the calculation formula of the ambient light intensity value may be: s (1+ X).
In some embodiments, the step of "adjusting the ambient light intensity detection value based on the target light intensity value to obtain the ambient light intensity value" may include the following processes:
acquiring a preset second adjusting coefficient;
calculating the product of the second adjustment coefficient and the target light intensity value to obtain a light intensity adjustment value;
and adjusting the ambient light intensity detection value according to the light intensity adjustment value to obtain an ambient light intensity value.
Similarly, the ambient light intensity detection value includes a light intensity value of a light emitting line of the display screen, and the target light intensity value detected by the colorsensor may include a light intensity value of a portion of ambient light in the external ambient light, so that the detected target light intensity value needs to be optimized to obtain a more accurate ambient light intensity adjustment value.
Specifically, if 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 of the ambient light intensity value may be: d- (Y x Z). Wherein, the value of Y is determined according to the ratio of Z to D.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, in the ambient light intensity detection method provided in the embodiment of the present application, the ambient light intensity detection value is obtained, then the RGB spectrum information of the detected light is determined, and then the target light intensity value of the target light matched between the RGB spectrum information and the sample RGB spectrum information is obtained, where 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, so as to obtain the ambient light intensity value. In the scheme, the electronic equipment can acquire corresponding data according to the RGB frequency spectrum information of the display screen to adjust the detection value of the ambient light sensor, so that the influence of light generated by the display screen to the intensity of ambient light detected by the electronic equipment is reduced, and the accuracy of the intensity of the ambient light is improved.
