An embodiment of the present disclosure provides a light intensity correction method, including: obtaining a light intensity detection value detected by the optical sensor; obtaining the light leakage intensity of the display panel in a lighting state under the condition that the current brightness is the first brightness; correcting the light intensity detection value by using the light leakage intensity under the current brightness to obtain the ambient light intensity; and adjusting the current brightness from the first brightness to a second brightness based on the ambient light intensity.
Fig. 1 schematically shows an application scenario of a light intensity correction method according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, the light intensity correction method according to the embodiment of the disclosure may be applied to a mobile phone 100, where the mobile phone 100 includes a light sensor 110, and for a partial full-screen mobile phone, in order to maximize a screen, the light sensor 110 is disposed on one side of a display screen or on a back of the screen, and then ambient light is transmitted to the light sensor 110 by using a light guide pillar, or a slit is left between the display screen and a bezel, and the ambient light is transmitted to the light sensor 110 by the slit. However, in this case, the light sensor 110 is affected by light leakage from the screen of the electronic device, and light from the screen is exposed from the side wall and projected onto the light sensor, which results in inaccurate measurement of ambient light by the light sensor. In the prior art, the light leakage of the screen is reduced by attaching a black barrier material on the side edge of the screen, but part of the light is still exposed, and the process complexity is increased.
The light intensity correction method of the embodiment of the disclosure can eliminate the influence of light leakage by means of calculation correction, obtain the light leakage intensity of the display screen when the screen is in a lighting state, correct the detection value of the optical sensor by using the light leakage intensity of the screen, and obtain more accurate ambient light intensity.
Fig. 2 schematically shows a flow chart of a light intensity correction method according to an embodiment of the present disclosure.
As shown in fig. 2, the light intensity correction method of the embodiment of the present disclosure may include operations S210 to S240:
in operation S210, a light intensity detection value detected by the light sensor is obtained.
The light intensity detection value is the light intensity value of all the light rays incident to the light sensor detected by the light sensor.
According to the embodiment of the present disclosure, it is necessary to determine whether the display panel is in a lit state. When the display panel is in a lit state, light leakage from the display panel may enter the light sensor, and the light intensity detected by the light sensor is affected by the light leakage from the display panel, so that the light intensity detection value needs to be corrected. And under the condition that the display panel is in the screen-off state, the detection value of the optical sensor has no influence of screen light leakage.
The display panel can have various display brightness, for example, ten brightness levels of level 1-level 10 can be set from dark to light, and the brightness of the display panel can be adaptively adjusted according to the intensity of the ambient light.
According to an embodiment of the present disclosure, if the display panel is currently in a lighting state and the luminance is a first luminance, obtaining a light intensity detection value detected by the light sensor includes: and under the condition that the brightness of the display panel in the lighting state is the first brightness, the light intensity detection value collected by the light sensor. In this case, the light intensity detection value of the light sensor is affected by light leakage of the display panel at the first luminance. The first brightness may be any one of level1 to level 10.
In operation S220, a light leakage intensity at which the current luminance of the display panel in the lit state is the first luminance is obtained.
When the display panel is at different brightness, the light leakage intensity of the display panel is different, but the light leakage intensity corresponding to each brightness is fixed. When the luminance of the display panel is the first luminance, the light leakage intensity corresponding to the first luminance may be obtained, and then the light intensity detection value may be corrected by using the light leakage intensity corresponding to the first luminance.
In operation S230, the light intensity detection value is corrected using the light leakage intensity at the current brightness, so as to obtain the ambient light intensity.
For example, the current leakage light intensity is subtracted from the detected light intensity value, and the result of calculation is used as the ambient light intensity.
In operation S240, the current brightness is adjusted from the first brightness to the second brightness based on the ambient light intensity.
After the ambient light intensity is obtained, the brightness of the display panel may be adjusted from the first brightness to a second brightness matched with the current ambient light intensity.
In addition, when the display panel is in the off state, the light intensity detection values obtained by the light sensors are all from the ambient light, and therefore, the luminance of the display panel can be adjusted directly based on the light intensity detection values.
According to the embodiment of the disclosure, under the condition that the screen is in a lighting state, the light leakage intensity corresponding to the current brightness is obtained, the detection value of the optical sensor is corrected by utilizing the light leakage intensity, and the intensity of real ambient light is obtained.
According to an embodiment of the present disclosure, the light intensity correction method of an embodiment of the present disclosure may further include:
if the light intensity detection value is smaller than the light leakage influence threshold value, performing to obtain the light leakage intensity of the display panel in the lighting state under the condition that the current brightness is the first brightness; correcting the light intensity detection value by using the light leakage intensity under the current brightness to obtain the ambient light intensity; and adjusting the current brightness from a first brightness to a second brightness based on the ambient light intensity; and
if the light intensity detection value is greater than the light leakage influence threshold value, the current brightness is adjusted from the first brightness to a third brightness based on the light intensity detection value.
According to practical tests, the intensity value of the light leakage of the display screen is approximately within the range of 20-50lux, the light leakage of the display screen can generate obvious interference on the optical sensor only when the ambient light intensity is below 500lux, when the ambient light intensity is greater than 500lux, for example, the outdoor ambient light intensity in daytime can reach more than 10000lux, the interference of the light leakage of the display screen on the optical sensor can be basically ignored, and therefore, the light intensity can be corrected only when the ambient light intensity is less than 500 lux.
The light leakage influence threshold may be, for example, 500lux, and when the light intensity detection value is less than 5001ux, it is necessary to obtain a light leakage intensity corresponding to the current brightness of the display panel in the lit state, correct the light intensity detection value by using the light leakage intensity at the current brightness to obtain an ambient light intensity, and then adjust the brightness of the display screen by the ambient light intensity. In the case where the light intensity detection value is greater than 500lux, the influence of screen leakage light is negligible, and thus the current luminance may be adjusted from the current first luminance to the third luminance based directly on the light intensity detection value.
Fig. 3 schematically shows a flow chart of a light intensity correction method according to another embodiment of the present disclosure.
As shown in fig. 3, obtaining the leakage light intensity at the luminance of the display panel at the first luminance, for example, in operation S220 shown in fig. 2, may further include the following operations S221 to S222, according to an embodiment of the present disclosure.
In operation S221, obtaining pre-stored correspondence information regarding a luminance state and a light leakage intensity; wherein, obtaining pre-stored information about correspondence between the luminance status and the light leakage intensity comprises: correspondence information on the luminance state and the leak light intensity is acquired from a storage device of the electronic apparatus.
In operation S222, the light leakage intensity corresponding to the first luminance is searched for from the correspondence information;
for example, before the mobile phone leaves the factory, the light leakage intensity corresponding to the brightness of each display screen may be stored in advance in the storage device of the mobile phone, and a correspondence table may be formed. The light leakage intensity corresponding to the brightness of each display screen can be obtained through experimental detection; or the light leakage intensity under one of the luminance conditions may be detected, for example, the light leakage intensity under the darkest level1 of the display screen is detected, and then the light leakage intensities under other luminance levels are calculated according to a certain proportion.
And under the condition that the current display screen brightness is the first brightness, for example, inquiring the pre-stored corresponding relation table to obtain the light leakage intensity corresponding to the first brightness as the current light leakage intensity.
Because each light leakage intensity obtained by proportional calculation before leaving the factory may not be very accurate, in the process of actually using the electronic device by a user, the light leakage intensity corresponding to the brightness of the display screen can be accurately detected, and the light leakage intensity corresponding to each brightness of the display screen in the corresponding relation table is corrected and updated. For example, the correspondence table may be updated through operations S250 to S270 described below.
According to an embodiment of the present disclosure, the light intensity correction method according to the present embodiment may further include the following operations S250 to S270, compared to the example light intensity correction method illustrated in fig. 2.
In operation S250, a first light intensity detection value of the display panel in the screen-off state and a second light intensity detection value of the display panel in the lighting state with the first brightness are obtained through a switching process of the display panel from the screen-off state to the lighting state.
According to an embodiment of the present disclosure, the switching process of the operation S250 from the screen-off state to the lighting state through the display panel includes the following operations:
(1) obtaining communication information;
(2) obtaining a first light intensity detection value of the display panel in a screen extinguishing state based on the communication information;
(3) the display panel is lightened by first brightness, and a reminding mark of the communication information is displayed; and (4) obtaining a second light intensity detection value that the display panel is in a lit state at the first luminance.
For example, when the mobile phone is in the screen-off state and a short message or an incoming call request is transmitted, a light intensity detection value of the optical sensor, for example, a first light intensity detection value, in the screen-off state of the mobile phone is obtained first. Then, the display screen is controlled to light the display screen at a certain brightness, for example, the display screen is lighted at a first brightness, and a short message reminder or an incoming call reminder is displayed on the display screen, and a light intensity detection value detected by the light sensor after the display screen is lighted at the first brightness, for example, a second light intensity detection value, is obtained.
In operation S260, a difference value of the second light intensity detection value and the first light intensity detection value is determined.
In operation S270, the light leakage intensity corresponding to the first luminance in the correspondence information is updated based on the difference value.
The difference between the detected light intensities before and after the display screen is lit at the first brightness can be regarded as the light leakage intensity value when the display screen is displayed at the first brightness, and the light leakage intensity corresponding to the first brightness in the correspondence table can be updated by using the difference.
According to the embodiment of the disclosure, in order to update the light leakage intensity corresponding to each brightness in the correspondence table as soon as possible, the display screen can be lighted up with different brightness each time a communication message is inserted, so that the updating operation of the correspondence table can be completed quickly.
According to the embodiment of the disclosure, through the above manner, the information in the table can be updated without disturbing the user, for example, when the mobile phone is idle on a desk, the display screen is in the screen off state, when a call or a WeChat is received, the mobile phone is switched from the screen off state to the on state, and the difference value of the light intensity sensed by the optical sensor before and after the conversion is the light leakage intensity of the screen under the current brightness. In this way, the updating of the correspondence table can be completed quickly without the user being aware of it.
In other embodiments of the present disclosure, if the correspondence table is not pre-stored before the mobile phone leaves the factory, the correspondence table between each brightness and the light leakage intensity may also be established in a manner similar to the above updating. And then, inquiring the light leakage intensity by using the established corresponding relation table.
In other embodiments of the present disclosure, the light leakage value may also be obtained in a manner that the correspondence table is not pre-stored and then is queried in the correction process, but the current light leakage value is measured in real time in the correction process. For example, in the correction process, the current screen is controlled to be changed from the lighting state to the screen-off state, the difference value measured by the optical sensor before and after the change is the current screen light leakage value, and the display screen is controlled to be changed from the screen-off state to the lighting state after the change is finished.
The embodiment of the disclosure also provides a light intensity correction device.
