When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure.

Fig. 1 is a flowchart illustrating a brightness adjustment method according to an exemplary embodiment, which is applied to an electronic device including a display screen, the electronic device further including a first light sensor oriented in the same direction as the display screen and a second light sensor oriented in a different direction from the display screen, as shown in fig. 1, and mainly includes the following steps:
in step 101, acquiring ambient light by using the first light sensor to obtain first acquired data, and acquiring ambient light by using the second light sensor to obtain second acquired data;
in step 102, a backlight parameter of the display screen is adjusted according to the first collected data and/or the second collected data.
The brightness adjusting method in the embodiment of the disclosure can be applied to an electronic device including a display screen, a first light sensor and a second light sensor, wherein the electronic device includes a mobile terminal and a fixed terminal. Here, the mobile terminal includes a mobile phone, a notebook computer, a tablet computer, a wearable electronic device, a smart speaker, and the like, and the fixed terminal includes a personal computer, a television, and the like. Here, the first light sensor and the second light sensor may sense light conditions such as light brightness of an environment in which the electronic device is located. In some embodiments, one or more first light sensors and one or more second light sensors may be provided on the electronic device. For example, when a plurality of first light sensors are provided, the orientations of the plurality of first light sensors are the same, and the orientations of the plurality of first light sensors are the same as the orientation of the display screen. When a plurality of second light sensors are arranged, the orientations of the plurality of second light sensors are the same, and the orientations of the plurality of second light sensors are different from the orientation of the display screen. In some embodiments, the orientation of the second light sensor may be opposite to the orientation of the second light sensor, or may be at a set angle, and is not particularly limited herein.
In the embodiment of the disclosure, the first light sensor with the same orientation as the display screen is used for collecting the ambient light to obtain the first collected data, the second light sensor with the different orientation as the display screen is used for collecting the ambient light to obtain the second collected data, and the collected data can be more comprehensive and accurate.
After the first and second collected data are obtained, backlight parameters of the display screen may be adjusted based on the first and/or second collected data. In some embodiments, the first collected data and the second collected data may be directly compared to obtain a comparison result, and then a corresponding adjustment policy is determined according to the comparison result, and the backlight parameter of the display screen is adjusted based on the adjustment policy.
The adjustment policy may be preset, for example, the first adjustment policy may be: adjusting backlight parameters based on the first collected data; the second adjustment strategy may be: adjusting the backlight parameter based on the second collected data. In some embodiments, the determining a corresponding adjustment policy according to the comparison result and adjusting the backlight parameter of the display screen based on the adjustment policy includes: if the comparison result represents that the first collected data is larger than the second collected data, adjusting the backlight parameter based on a first adjusting strategy; and if the comparison result indicates that the first acquisition data is smaller than the second acquisition data, adjusting the backlight parameter based on a second adjustment strategy. Here, the backlight parameter may include: brightness value and contrast of the display screen.
In other embodiments, the first collected data and the second collected data may be weighted and then summed, and the backlight parameter of the display screen may be adjusted based on the summation result.
In the embodiment of the disclosure, a first light sensor with the same orientation as the display screen may be used to obtain first collected data, a second light sensor with the different orientation from the display screen may be used to obtain second collected data, and the backlight parameter of the display screen may be adjusted according to the first collected data and/or the second collected data. Therefore, the backlight parameter of the display screen can be adjusted according to the first collected data and/or the second collected data, so that the backlight parameter of the display screen can be adapted to the environment around the electronic equipment, the possibility of visual fatigue of a user due to the fact that the backlight parameter is not appropriate is reduced, better experience is brought to the user in the aspect of impression, and the user experience degree is improved.
In some embodiments, said adjusting a backlight parameter of said display screen according to said first collected data and/or said second collected data comprises:
adjusting the backlight parameter based on the first collected data if the first collected data is greater than or equal to a set threshold.
Here, the first collected data may be a first illuminance value obtained from the collected ambient light by the first light sensor, the second collected data may be a second illuminance value obtained from the collected ambient light by the second light sensor, the set threshold may be a preset illuminance threshold, for example, an illuminance threshold obtained from an experiment, or an illuminance threshold set empirically, and further, for example, the set threshold may be 200lux (lux).
In the embodiment of the disclosure, it may be determined whether the first collected data is greater than or equal to the set threshold, and in a case that the first collected data is greater than or equal to the set threshold, the backlight parameter of the display screen may be directly adjusted based on the first collected data.
In an application scenario, most of the light sources are illuminated from above the electronic device, for example, an indoor artificial light source and an outdoor ambient light, and most of the light sources are located above the electronic device. When the first collected data collected by the first light sensor with the same orientation as the display screen of the electronic equipment is larger than the set threshold value, the current light source is brighter, and the display screen faces the light source at the set angle.
In the embodiment of the disclosure, a set threshold may be preset, the first collected data may be compared with the set threshold, and when the first collected data is greater than or equal to the set threshold, the backlight parameter may be adjusted directly based on that the first collected data is equal to the set threshold, so as to simplify the adjustment process of the backlight parameter on the basis of ensuring the accuracy of the collected data.
In some embodiments, said adjusting backlight parameters of said display screen based on said first collected data and/or said second collected data comprises:
if the first collected data is smaller than the set threshold value and the first collected data is larger than the second collected data, adjusting the backlight parameter based on the first collected data;
and if the first collected data is smaller than the set threshold value and the first collected data is smaller than the second collected data, adjusting the backlight parameter based on the second collected data.
In some embodiments, if the first collected data is less than the set threshold, the light source indicating the current display screen is facing the direction is dark, or the back of the electronic device is facing the light source, for example, if the user uses the electronic device on a window in the morning or uses the electronic device under a street lamp at night, the back of the electronic device may be facing the light source, and this is less effective if the backlight parameters are adjusted based on the first collected data only.
In the embodiment of the disclosure, when the first collected data is smaller than the set threshold, the first collected data and the second collected data may be compared to obtain a comparison result, and the backlight parameter of the display screen may be adjusted according to the comparison result. If the first collected data is larger than the second collected data, adjusting the backlight parameters based on the first collected data; and when the second collected data is larger than the first collected data, adjusting the backlight parameters based on the second collected data.
In the embodiment of the disclosure, under the condition that the first collected data is smaller than the set threshold, the larger collected data can be selected from the first collected data and the second collected data as the basis for adjusting the backlight parameter, so that different adjustment strategies can be selected for different application scenes to adjust the backlight parameter, and the backlight parameter of the display screen can be more adaptive to the environment around the electronic device.
In some embodiments, the display screen according to the embodiments of the present disclosure is a display screen having a backlight, for example, a Light Emitting Diode (LED) may be used as a backlight of the display screen of the electronic device.
In some embodiments, the method further comprises:
detecting a data variation of the second collected data in a case where the backlight parameter is adjusted based on the second collected data;
and when the data variation is larger than a set variation threshold, switching to the adjustment of the backlight parameter based on the first acquisition data.
Here, in the case of adjusting the backlight parameter based on the second collected data, it is possible to detect a change of the second collected data and determine a data change amount of the second collected data, where the data change amount may be a change width of the second collected data. For example, if a change in the second acquisition data from 150lux to 5lux is detected, the data change amount is 145 lux.
In the embodiment of the disclosure, after the data variation of the second collected data is detected, the data variation may be compared with a set variation threshold, and when the data variation is greater than the set variation threshold, the backlight parameter is adjusted based on the first collected data. Here, the set change threshold may be a preset illuminance change threshold, and may be, for example, an illuminance change threshold obtained by an experiment or an illuminance change threshold set empirically.
For another example, the set change threshold may be 50lux, or the second collected data is changed from 150lux to 5lux, for example, since the data change amount is 145lux and is greater than 50lux, at this time, it may be determined that the second light sensor may not detect the light source, if the adjustment of the backlight parameter is continued based on the second collected data obtained by the second light sensor, the adjustment parameter of the display screen may not be suitable for the current environment, at this time, it is necessary to switch to adjusting the backlight parameter based on the first collected data, so as to improve the accuracy of adjusting the backlight parameter.
In some embodiments, when the data variation is greater than a set variation threshold, switching to adjusting the backlight parameter based on the first collected data includes: when the data variation is larger than a set variation threshold, determining target data to which the second acquired data is changed; determining whether the target data is less than or equal to a set data threshold; and if the target data is less than or equal to a set data threshold value, switching to adjusting the backlight parameter based on the first acquisition data.
Here, the set data threshold may be a preset data threshold, for example, a data threshold obtained by experiment or a data threshold set empirically. As another example, the set data threshold may be 5 lux. For example, if a change in the second acquisition data from 150lux to 5lux is detected, the data change is 145lux and the target data is 5lux, and since 5lux is equal to the set data threshold, then a switch may be made to adjust the backlight parameter based on the first acquisition data. Since it may be determined that the second light sensor may not detect the light source in the case that the target data is smaller than the set data threshold, it is necessary to switch to adjusting the backlight parameter based on the first collected data to improve the accuracy of adjusting the backlight parameter.
Fig. 2 is a flowchart illustrating a brightness adjustment method according to an exemplary embodiment, where as shown in fig. 2, the method mainly includes the following steps:
in step 201, acquiring ambient light by using the first light sensor to obtain first acquired data, and acquiring ambient light by using the second light sensor to obtain second acquired data;
in step 202, obtaining a target backlight parameter of the display screen according to the first collected data and/or the second collected data;
in step 203, the backlight parameter of the display screen is adjusted to the target backlight parameter.
In the implementation process, a set function can be used to obtain the target backlight parameter of the display screen according to the first collected data and/or the second collected data. Here, the backlight parameter may include a luminance value of the display screen, and taking the backlight parameter as the luminance value of the display screen as an example, a conversion formula between the collected data and the backlight parameter is as follows:
y＝lnx (1)；
in formula (1), x represents the detected collected data, and y represents the brightness value of the display screen.
For example, in the case of adjusting the backlight parameter based on the first collected data, the setting function may be used to obtain the target backlight parameter based on the first collected data. In the case where the backlight parameter is adjusted based on the second collected data, the target backlight parameter may be obtained based on the second collected data using the setting function. In the embodiment of the disclosure, the electronic device can automatically adjust the brightness and the contrast of the display screen based on the first collected data and/or the second collected data so as to be suitable for the function of being watched by human eyes. That is to say, can turn down luminance and contrast at the darker environment of light, can turn up luminance and contrast at the stronger environment of light, not only can improve the comfort level that the people's eye watched, can also play the effect of protection eyesight.
Fig. 3 is a flowchart illustrating a brightness adjustment method according to an exemplary embodiment, as shown in fig. 3, the method mainly includes the following steps:
in step 301, acquiring ambient light by using the first light sensor to obtain first acquired data, and acquiring ambient light by using the second light sensor to obtain second acquired data;
in step 302, adjusting a backlight parameter of the display screen according to the first collected data and/or the second collected data;
in step 303, acquiring posture information of the electronic device during the process of adjusting the backlight parameter according to the first collected data and/or the second collected data;
in step 304, adjusting the adjusting speed of the backlight parameter according to the posture information.
Here, the posture information of the electronic device may be obtained based on acceleration information collected by an acceleration sensor included in the electronic device and angle information collected by a gyro sensor, and the adjustment speed of the backlight parameter may be adjusted according to the posture information. For example, the current attitude information of the electronic device is determined according to the components of the gravity acceleration acquired by the acceleration sensor on three axes of an x axis, a y axis and a z axis in a cartesian coordinate system, and whether the display screen of the electronic device faces the light source is judged according to the attitude information. In some embodiments, since the first light sensor is oriented in the same direction as the display screen of the electronic device, the first light sensor is also oriented toward the light source when the display screen of the electronic device is oriented toward the light source. Because when the contained angle of electronic equipment's display screen and horizontal plane is great, it is great to show the contained angle of first light sensor's light collection face and horizontal plane, and at this moment, most light of light source may shine on first light sensor's visual angle edge, and the first data of gathering produce great number value change easily, and the change of this number value can lead to the change of the great range of parameter and great speed in a poor light, so need reduce the governing speed of parameter in a poor light.
That is to say, under the condition that it is determined that the display screen of the electronic device faces the light source, it may be determined whether an included angle between the display screen of the electronic device and the horizontal plane is greater than or equal to a set angle threshold, and when the included angle between the display screen of the electronic device and the horizontal plane is greater than or equal to the set angle threshold, the adjustment speed of the backlight parameter is reduced. In some embodiments, when the included angle between the display screen of the electronic device and the horizontal plane is smaller than the set angle threshold, the adjusting speed of the backlight parameter is maintained or increased.
In the embodiment of the disclosure, the use scene can be judged according to the posture information of the electronic device, and the adjustment speed of the backlight parameter is adaptively adjusted according to the use scene, so that the final display brightness and contrast of the display screen can be more matched with the current use scene.
In the embodiment of the present disclosure, data of a first Light Sensor (front Ambient Light Sensor (ALS)) is used as a main component, when first collected data of the first Light Sensor changes, second collected data obtained by referring to a current second Light Sensor (back ALS) is started, a larger value of the first collected data and the second collected data is selected, and a backlight parameter of a display screen is adjusted based on the larger value.
In some embodiments, the adjustment strategy is suitable for the case that the first collected data is less than 200lux, and in the case that the first collected data is greater than or equal to 200lux, the backlight parameter may be adjusted directly based on the first collected data.
In one application scenario, most of the light sources are illuminated from above the electronic device, for example, an indoor artificial light source and an outdoor ambient light, and most of the light sources are located above the electronic device, and the first collected data (front light sensation value) is larger than the second collected data (back light sensation value). If the user uses the electronic device on a window in the morning or uses the electronic device under a street lamp at night, the second collected data is larger than the first collected data, and at the moment, the second collected data is smaller than 200 lux.
In some embodiments, in the case of adjusting the backlight parameter based on the second collected data, if the data change amount (change width) of the second collected data exceeds the set change threshold (brightness change threshold) and the target data (target value) is lower than 5lux, it indicates that there is no light source on the back surface of the electronic device, and at this time, it may be switched to adjusting the backlight parameter based on the first collected data. In the embodiment of the disclosure, data input can be provided for adjusting the backlight parameter by the first collected data obtained according to the first light sensor and the second collected data obtained according to the second light sensor, and the electronic device can adjust the brightness of the display screen according to the first collected data and the second collected data.
