Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The Mobile terminal according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal.
The following describes embodiments of the present application in detail.
Referring to fig. 1, fig. 1 is a schematic flow chart of a backlight brightness adjusting method disclosed in an embodiment of the present application, and as shown in fig. 1, the backlight brightness adjusting method includes the following steps.
101, when the backlight brightness of the mobile terminal is set to the manual adjustment mode, the mobile terminal starts the backlight protection mode.
In the embodiment of the application, the backlight brightness of the mobile terminal can be set to be in an automatic adjustment mode or a manual adjustment mode. In the auto-adjustment mode, the backlight brightness of the terminal may be adjusted according to a change in the ambient light intensity. In the manual adjustment mode, the backlight brightness of the terminal is manually set by a user, and if the backlight protection mode is not started, once the backlight brightness is set, the backlight brightness of the mobile terminal is fixed.
The display module of the mobile terminal generally includes: display screen (e.g., liquid crystal display), backlight (e.g., LED backlight), drive circuit, connecting piece and control circuit. The backlight is located the back of display screen, and the display screen itself is not luminous, and display screen display figure or character are the result that the display module assembly modulated the light that the backlight produced. The backlight generally includes a light source (e.g., an LED lamp), a light guide plate (e.g., the light guide plate may be made of an acrylic material), an optical film, and a plastic frame. The light source is provided with a light guide plate, and the light guide plate is provided with an optical film. The light guide plate and the optical film can convert light generated by the light source into uniform light.
In the embodiment of the present application, adjusting the backlight brightness of the mobile terminal refers to adjusting the brightness of the backlight source.
102, the mobile terminal detects whether a first backlight brightness manually set by the mobile terminal is greater than a preset brightness threshold corresponding to the backlight protection mode.
103, if the first backlight brightness is greater than the preset brightness threshold, when the screen-on duration of the mobile terminal under the first backlight brightness exceeds the preset duration corresponding to the backlight protection mode, the mobile terminal detects the ambient light intensity through the light sensor.
And 104, when the ambient light intensity is smaller than the preset intensity threshold, the mobile terminal adjusts the backlight brightness of the mobile terminal to a second backlight brightness, and the second backlight brightness is smaller than the preset brightness threshold.
In the embodiment of the application, when the backlight brightness of the mobile terminal is set to be in the manual regulation mode, the backlight protection is automatically started. Referring to fig. 2, fig. 2 is a schematic diagram of a backlight brightness adjusting interface according to an embodiment of the disclosure. As shown in fig. 2, a backlight brightness display bar, an automatic brightness adjustment option and a backlight protection option may be displayed on the backlight brightness adjustment interface. The backlight brightness display bar in fig. 2 has a slider, and a user can manually drag the slider to adjust the backlight brightness. The automatic brightness adjustment option in fig. 2 is not turned on, indicating that the current backlight brightness adjustment is in the manual adjustment mode in which the backlight protection option is automatically selected to be turned on. The backlight brightness adjustment interface of fig. 2 may be entered by a user from a setup interface of the mobile terminal.
In the backlight protection mode, a preset brightness threshold and a preset duration may be set. Step 102 and step 103 are specific methods for determining whether the backlight protection condition is satisfied. Step 104 is a backlight brightness adjusting method under the condition of satisfying the backlight protection. The preset brightness threshold and the preset duration can be set by a system or a user. For example, the preset brightness threshold may be set to 80% of the maximum backlight brightness, and the preset duration may be set to 10 minutes. In general, the preset brightness threshold may be set between 70% and 90%, and the preset time period may be set between 5 and 30 minutes. The embodiment of the present application is not limited to the setting of the preset brightness threshold and the preset duration.
A light sensor, also known as an ambient light sensor, may be used to detect the intensity of ambient light. The light sensor may include a photosensor for converting the collected light signal into an electrical signal and an analog-to-digital converter for converting the electrical signal into a digital signal. Optionally, the light sensor may further include a signal amplifier, and the signal amplifier may amplify the electrical signal converted by the photosensitive element and output the amplified electrical signal to the analog-to-digital converter. The photosensitive element may include at least one of a photodiode, a phototransistor, a photoresistor, and a silicon photocell.
The preset intensity threshold may be preset and stored in the non-volatile memory of the mobile terminal. For example, the preset intensity threshold may be set to 1000 lux. In general, the preset intensity threshold may be set between 500 and 2000 lux.
When the ambient light intensity is smaller than the preset intensity threshold, the mobile terminal is indicated to be in a dark scene, and when the ambient light intensity is smaller than the preset intensity threshold, the backlight brightness of the mobile terminal is reduced, so that the electric quantity of the mobile terminal can be saved in a manual adjusting mode. The second backlight luminance may be set to a fixed value or may be set to a magnitude corresponding to the intensity of ambient light. For example, the second backlight luminance may be set to a fixed value of 20% of the maximum backlight luminance. For another example, the corresponding relationship between the ambient light intensity and the second backlight brightness can be seen in table 1. As shown in table 1, table 1 is a table of correspondence between ambient light intensity and second backlight brightness disclosed in the embodiments of the present application.
TABLE 1
As can be seen from table 1, when the ambient light intensities are in different ranges, the corresponding second backlight luminances are different. For example, if the ambient light intensity is 400lux, the corresponding second backlight brightness is 35%.
In the embodiment of the application, the backlight protection mode can be automatically started when the backlight brightness is set to be the manual regulation mode, and the backlight brightness of the mobile terminal is reduced when the backlight protection condition is met, so that the backlight brightness of the mobile terminal can be timely regulated in the manual regulation mode, and the electric quantity of the mobile terminal is saved.
Referring to fig. 3, fig. 3 is a schematic flow chart of another backlight brightness adjusting method disclosed in the embodiment of the present application, and fig. 3 is obtained by further optimizing on the basis of fig. 1. As shown in fig. 3, the backlight brightness adjusting method includes the following steps.
301, when the backlight brightness of the mobile terminal is set to the manual adjustment mode, the mobile terminal starts the backlight protection mode.
302, the mobile terminal detects whether a first backlight brightness manually set by the mobile terminal is greater than a preset brightness threshold corresponding to the backlight protection mode. If yes, go to step 303, otherwise, go to step 302.
The steps 301-302 in the embodiment of the present application can refer to the steps 101 to 102 shown in fig. 1, which are not described herein again.
303, the mobile terminal determines whether the screen-on duration under the first backlight brightness exceeds a preset duration corresponding to the backlight protection mode. If yes, go to step 304; if not, the process ends and continues to step 303.
304, the mobile terminal detects whether the mobile terminal is switched from the screen-off state to the screen-on state. If yes, go to step 305; if not, go to step 304.
In the embodiment of the application, when the screen-on duration of the mobile terminal under the first backlight brightness exceeds the preset duration corresponding to the backlight protection mode, the backlight brightness adjustment is not immediately performed, but the backlight brightness adjustment corresponding to the backlight protection is performed when the screen is next lit, so that the backlight brightness is not adjusted when the user is using in order to not disturb the user. When the mobile terminal detects that the backlight protection condition is met, the backlight brightness is not adjusted immediately, but the backlight adjustment strategy corresponding to the backlight protection mode is executed only when the mobile terminal is turned off and the screen is turned on next time, the backlight brightness is not adjusted when the user uses the mobile terminal, and the user experience can be improved.
The mobile terminal detects the intensity of ambient light by a light sensor 305.
306, when the ambient light intensity is smaller than the preset intensity threshold, the mobile terminal adjusts the backlight brightness of the mobile terminal to a second backlight brightness, and the second backlight brightness is smaller than the preset brightness threshold.
The steps 305-306 in the embodiment of the present application can refer to the steps 103 to 104 shown in fig. 1, which are not described herein again.
In the embodiment of the application, the backlight protection mode can be automatically started when the backlight brightness is set to be the manual regulation mode, the backlight brightness cannot be immediately regulated when the backlight protection condition is met, the backlight regulation strategy corresponding to the backlight protection mode is executed only when the screen of the mobile terminal is turned off and is turned on next time, the backlight brightness cannot be regulated when a user is using the mobile terminal, and the user experience can be improved.
Referring to fig. 4, fig. 4 is a schematic flowchart of another backlight brightness adjusting method disclosed in an embodiment of the present application, and fig. 4 is obtained by further optimizing on the basis of fig. 1. As shown in fig. 4, the backlight brightness adjusting method includes the following steps.
401, when the backlight brightness of the mobile terminal is set to the manual adjustment mode, the mobile terminal starts the backlight protection mode.
402, the mobile terminal detects whether a first backlight brightness manually set by the mobile terminal is greater than a preset brightness threshold corresponding to the backlight protection mode.
And 403, if the first backlight brightness is greater than the preset brightness threshold, when the screen-on duration of the mobile terminal under the first backlight brightness exceeds the preset duration corresponding to the backlight protection mode, the mobile terminal detects the ambient light intensity through the light sensor.
Steps 401-403 in the embodiment of the present application may refer to steps 101 to 103 shown in fig. 1, which are not described herein again.
404, when the intensity of the ambient light is smaller than the preset intensity threshold, the mobile terminal detects whether the proximity sensor of the mobile terminal is shielded.
405, if the mobile terminal is not shielded, the mobile terminal adjusts the backlight brightness of the mobile terminal to a second backlight brightness, and the second backlight brightness is smaller than the preset brightness threshold.
In the embodiment of the application, when the proximity sensor is shielded, the mobile terminal does not perform backlight brightness adjustment. The mobile terminal may detect whether the proximity sensor is shielded through the proximity sensor. The embodiment of the application is suitable for the scene that the mobile terminal is placed in a bag or a pocket. In the above scenario, both the light sensor and the proximity sensor of the mobile terminal are shielded, which results in inaccurate ambient light intensity measured by the light sensor. Therefore, the backlight protection mode of the present application needs to exclude the above-mentioned scenes, and when the above-mentioned scenes occur, the backlight brightness adjustment is not performed. The embodiment of the application can improve the accuracy of backlight brightness adjustment.
In the embodiment of the application, the backlight protection mode can be automatically started when the backlight brightness is set to be the manual regulation mode, and the backlight brightness of the mobile terminal is reduced when the backlight protection condition is met, so that the backlight brightness of the mobile terminal can be timely regulated in the manual regulation mode, and the electric quantity of the mobile terminal is saved. According to the embodiment of the application, when the ambient light intensity measured by the light sensor is inaccurate, the backlight brightness adjustment is refused, and the accuracy of the backlight brightness adjustment can be improved.
Referring to fig. 5, fig. 5 is a schematic flowchart of another backlight brightness adjusting method disclosed in an embodiment of the present application, and fig. 5 is obtained by further optimizing on the basis of fig. 1. As shown in fig. 5, the backlight brightness adjusting method includes the following steps.
501, when the backlight brightness of the mobile terminal is set to the manual adjustment mode, the mobile terminal starts the backlight protection mode.
502, the mobile terminal detects whether a first backlight brightness manually set by the mobile terminal is greater than a preset brightness threshold corresponding to the backlight protection mode.
503, if the first backlight brightness is greater than the preset brightness threshold, when the screen-on duration of the mobile terminal at the first backlight brightness exceeds the preset duration corresponding to the backlight protection mode, the mobile terminal detects the ambient light intensity through the light sensor.
Steps 501-503 in the embodiment of the present application can refer to steps 101 to 103 shown in fig. 1, which are not described herein again.
Optionally, after the step 502 is executed, the following steps may also be executed:
and when the first backlight brightness manually set by the mobile terminal is greater than the preset brightness threshold corresponding to the backlight protection mode, adjusting the color of the backlight brightness display bar of the backlight brightness adjusting interface to be the warning color. In the manual adjustment mode, when the manually adjusted backlight brightness is high, the user is prompted through the display of the backlight brightness display bar, and the user is prompted to cause certain damage to human eyes if the user is in the backlight brightness for a long time.
Wherein, the warning color can play a role of warning the user. Generally, the alert color is a dark color, such as red, dark red, and the like. Specifically, please refer to fig. 6, where fig. 6 is a schematic diagram of a backlight luminance display bar disclosed in the embodiment of the present application. Compared with fig. 2, the backlight brightness display bar in fig. 6 is darker in color and has a warning effect.
Optionally, the color shade of the warning color may also be related to the magnitude of the first backlight brightness. Generally, the greater the first backlight brightness, the darker the color of the warning color, and the more prominent the warning effect. For example, the warning color is light red when the first backlight brightness is 70% -80% of the maximum backlight brightness, red when the first backlight brightness is 80% -90% of the maximum backlight brightness, and dark red when the first backlight brightness is 90% -100% of the maximum backlight brightness.
And 504, when the intensity of the ambient light is smaller than the preset intensity threshold, the mobile terminal identifies the scene where the mobile terminal is located.
505, when the scene where the mobile terminal is located is an indoor scene, the mobile terminal adjusts the backlight brightness of the mobile terminal to a second backlight brightness, and the second backlight brightness is smaller than the preset brightness threshold.
In the embodiment of the application, the mobile terminal identifies the scene where the mobile terminal is located through the light sensor. For example, when the optical sensor detects that the ambient light intensity is less than 1000lux, the scene in which the mobile terminal is located is considered as an indoor scene.
Optionally, the mobile terminal may also assist in identifying a scene where the mobile terminal is located through the camera, the WiFi module, and the GPS module.
In a possible implementation manner, the manner of identifying the scene where the mobile terminal is located by the mobile terminal is specifically as follows:
the mobile terminal shoots at least two pictures through a camera and identifies whether the at least two pictures contain the characteristics of an indoor scene;
and if so, determining that the scene where the mobile terminal is located is an indoor scene.
The specific feature that the mobile terminal identifies whether the at least two pictures contain the indoor scene is as follows:
and the mobile terminal compares the at least two pictures with the pictures of the pre-stored indoor scene respectively and judges whether the at least two pictures contain the characteristics in the pictures of the indoor scene. The feature in the picture refers to a specific object in the picture, such as a specific floor, a ceiling, a door, a window, and the like. According to the embodiment of the application, whether the scene where the mobile terminal is located is an indoor scene is identified through the camera, the specific scene where the mobile terminal is located can be further judged through the camera, and the accuracy of scene judgment is improved.
In a possible implementation manner, the manner of identifying the scene where the mobile terminal is located by the mobile terminal is specifically as follows:
the mobile terminal detects the signal intensity of a preset WiFi hotspot connected through the WiFi module, and if the detected signal intensity is larger than a preset signal intensity threshold value, the scene where the mobile terminal is located is considered as an indoor scene.
In the case that a WiFi hotspot (for example, a WiFi router) is generally placed indoors, and the mobile terminal is connected to the WiFi hotspot, the farther the distance between the mobile terminal and the WiFi router is, the weaker the WiFi signal of the mobile terminal is, and the closer the distance between the mobile terminal and the WiFi router is, the stronger the WiFi signal of the mobile terminal is. The preset WiFi hotspot can be preset, and the preset WiFi hotspot can be a WiFi hotspot in an office, a WiFi hotspot in a home, and the like. The mobile terminal can detect the WiFi signal strength of the mobile terminal through the WiFi module, the specific scene where the mobile terminal is located is determined through the WiFi signal strength, and the specific scene where the mobile terminal is located can be accurately determined.
When the scene where the mobile terminal is located is identified as an indoor scene, backlight brightness adjustment can be performed according to backlight brightness corresponding to the indoor scene. In an indoor scene, different ambient light intensities may correspond to different second backlight luminances. The specific correspondence is not limited herein.
In the embodiment of the application, the backlight protection mode can be automatically started when the backlight brightness is set to be the manual regulation mode, and the backlight brightness of the mobile terminal is reduced when the backlight protection condition is met, so that the backlight brightness of the mobile terminal can be timely regulated in the manual regulation mode, and the electric quantity of the mobile terminal is saved. The backlight brightness adjustment can be carried out according to specific indoor scenes, and the accuracy of the backlight brightness adjustment is improved.
