In the embodiment of the present application, the mobile terminal may include a light sensor, and the light sensor, also referred to as an ambient light sensor, may be configured to detect an intensity of ambient light. The mobile terminal may store a corresponding relationship between the ambient light intensity and the backlight brightness. As shown in table 1, table 1 is a table of correspondence between ambient light intensity and 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 backlight luminances are different. For example, if the first ambient light intensity is 400lux, the corresponding first backlight brightness is 35% of the maximum backlight brightness.

The mobile terminal informs the display terminal to display the playing content with the first backlight brightness, which specifically comprises:

the mobile terminal sends backlight brightness adjustment instructions to the display terminal, and the backlight brightness adjustment instructions carry first backlight brightness. And after the display terminal receives the backlight brightness adjusting instruction sent by the mobile terminal, adjusting the backlight brightness of the display terminal to be the first backlight brightness.

The display module of the display 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 light guide plate and the optical film can convert light generated by the light source into uniform light.

In the embodiment of the application, the display terminal displays the playing content with the first backlight brightness, which means that the brightness of the backlight source of the display terminal is adjusted to the first backlight brightness.

In the embodiment of the application, when the display terminal cannot automatically adjust the backlight brightness of the display terminal, the display terminal can control the backlight brightness of the display terminal through the mobile terminal, and the display brightness of the display terminal can be automatically adjusted according to the ambient light intensity collected by the mobile terminal when the display terminal displays the playing content, so that the visual experience of a user watching the display terminal is improved.

Referring to fig. 2, fig. 2 is a schematic flow chart of another screen projection brightness adjustment method disclosed in the embodiment of the present application, and fig. 2 is obtained by further optimizing on the basis of fig. 1 b. As shown in fig. 2, the screen brightness adjusting method includes the following steps.

And 201, after the mobile terminal is connected with the display terminal, transmitting the playing content of the mobile terminal to the display terminal, wherein the display terminal is used for displaying the playing content.

202, the mobile terminal obtains the first ambient light intensity through the light sensor.

The steps 201-202 in the embodiment of the present application can refer to the steps 101-102 shown in fig. 1b, which are not described herein again.

203, when the first ambient light intensity is smaller than the first preset intensity threshold, the mobile terminal detects whether the light sensor is shielded. If yes, go to step 204, otherwise go to step 205.

And 204, the mobile terminal outputs prompt information, and the prompt information is used for prompting that the light ray sensor is shielded.

In the embodiment of the application, when the mobile terminal detects that the intensity of the first ambient light obtained by the light sensor is small, the mobile terminal can judge whether the light sensor is shielded through the proximity sensor, if the light sensor is shielded, the mobile terminal considers that the intensity of the first ambient light obtained by the mobile terminal through the light sensor is inaccurate, the user needs to be prompted that the light sensor is shielded, and the user can be further prompted to move away the shielding object of the light sensor. The light sensor and the proximity sensor may be integrated together or may be respectively located at different positions of a display panel of the mobile terminal. The embodiment of the application is suitable for the scene that the display panel of the mobile terminal is placed on a desk or a sofa downwards, and is also 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. In general, in order to reduce power consumption of a mobile terminal, the mobile terminal does not turn on a proximity sensor in real time, and turns on the proximity sensor only in a scene such as a call. The embodiment of the application can compare the first ambient light intensity collected by the light sensor with the first preset intensity threshold value, and when the first ambient light intensity is smaller than the first preset intensity threshold value, the light sensor is prompted to be shielded by outputting the prompt information, so that the condition that the deviation occurs in backlight brightness adjustment due to the fact that the light sensor is shielded can be avoided.

The first preset intensity threshold may be preset and stored in the non-volatile memory of the mobile terminal. The first preset intensity threshold may be set to be less than 50lux, for example, to be set to any one of 10lux, 20lux, 30lux, and 40 lux.

Optionally, after step 204 is executed, if it is still detected that the light sensor is blocked, determining the backlight brightness corresponding to the ambient light intensity by using the intensity of the ambient light which is obtained by the light sensor last time and is greater than the first preset intensity threshold, and notifying the display terminal to display the playing content by using the backlight brightness.

205, the mobile terminal determines a first backlight brightness corresponding to the first ambient light intensity according to the corresponding relationship between the ambient light intensity and the backlight brightness.

And 206, the mobile terminal informs the display terminal to display the playing content at the first backlight brightness.

Step 205-.

In the embodiment of the application, when the display terminal cannot automatically adjust the backlight brightness of the display terminal, the display terminal can control the backlight brightness of the display terminal through the mobile terminal, and the display brightness of the display terminal can be automatically adjusted according to the ambient light intensity collected by the mobile terminal when the display terminal displays the playing content, so that the visual experience of a user watching the display terminal is improved. Meanwhile, the light sensor is prompted to be shielded by outputting prompt information, so that the condition that the backlight brightness adjustment is deviated due to the fact that the light sensor is shielded can be avoided.

Referring to fig. 3, fig. 3 is a schematic flow chart of another screen projection brightness adjustment method disclosed in the embodiment of the present application, and fig. 3 is obtained by further optimizing on the basis of fig. 1 b. As shown in fig. 3, the screen brightness adjusting method includes the following steps.

301, after the mobile terminal and the display terminal are connected, transmitting the playing content of the mobile terminal to the display terminal, where the display terminal is used to display the playing content.

302, the mobile terminal obtains a first ambient light intensity through the light sensor, and the mobile terminal determines a first backlight brightness corresponding to the first ambient light intensity according to a corresponding relationship between the ambient light intensity and the backlight brightness.

303, the mobile terminal informs the display terminal to display the playing content with the first backlight brightness.

The steps 301-303 in the embodiment of the present application can refer to the steps 101-103 shown in fig. 1b, which are not described herein again.

And 304, the mobile terminal receives the second ambient light intensity collected by the display terminal.

305, the mobile terminal determines whether the difference between the first ambient light intensity and the second ambient light intensity is greater than a second preset intensity threshold. If yes, go to step 306 and step 307, otherwise go to step 303.

In the embodiment of the application, the display terminal is added with an ambient light intensity acquisition function. The display terminal may also include a light sensor and may also collect a second ambient light intensity. The mobile terminal may compare whether a difference between the first ambient light intensity and the second ambient light intensity is greater than a second preset intensity threshold, if so, it is determined that one of the measured ambient light intensities of the mobile terminal and the display terminal is inaccurate, and the mobile terminal further determines whether a light sensor of the mobile terminal is blocked, and step 306 is executed. If not, the mobile terminal determines that the accuracy of the ambient light intensities measured by the mobile terminal and the display terminal is higher, and executes step 303.

The second preset intensity threshold may be preset and stored in the non-volatile memory of the mobile terminal. The second preset intensity threshold may be set to be less than 100lux, for example, may be set to be any one of 50lux, 60lux, 70lux, and 80 lux.

And 306, the mobile terminal detects whether the light sensor is shielded, and if the light sensor is shielded, the mobile terminal determines second backlight brightness corresponding to the second ambient light intensity according to the corresponding relation between the ambient light intensity and the backlight brightness.

307, the mobile terminal informs the display terminal to display the playing content with the second backlight brightness.

The corresponding relationship between the ambient light intensity and the backlight brightness can be seen in table 1, and is not described herein again. When the light optical sensor of the mobile terminal is shielded, the mobile terminal adjusts the backlight brightness by taking the second ambient light intensity collected by the display terminal as the standard, and the accuracy of backlight brightness adjustment can be improved when the light optical sensor of the mobile terminal is shielded.

In the embodiment of the application, when the display terminal cannot automatically adjust the backlight brightness of the display terminal, the display terminal can control the backlight brightness of the display terminal through the mobile terminal, and the display brightness of the display terminal can be automatically adjusted according to the ambient light intensity collected by the mobile terminal when the display terminal displays the playing content, so that the visual experience of a user watching the display terminal is improved. When the light optical sensor of the mobile terminal is shielded, the mobile terminal adjusts the backlight brightness by taking the second ambient light intensity collected by the display terminal as the standard, and the accuracy of backlight brightness adjustment can be improved when the light optical sensor of the mobile terminal is shielded.

Referring to fig. 4, fig. 4 is a schematic flow chart of another screen projection brightness adjustment method disclosed in the embodiment of the present application, and fig. 4 is obtained by further optimizing on the basis of fig. 1 b. As shown in fig. 4, the screen brightness adjusting method includes the following steps.

401, after the mobile terminal establishes a connection with the display terminal, transmitting the playing content of the mobile terminal to the display terminal, where the display terminal is used to display the playing content.

402, the mobile terminal obtains a first ambient light intensity through the light sensor, and the mobile terminal determines a first backlight brightness corresponding to the first ambient light intensity according to a corresponding relationship between the ambient light intensity and the backlight brightness.

And 403, the mobile terminal informs the display terminal to display the playing content with the first backlight brightness.

The steps 401-403 in the embodiment of the present application can refer to the steps 101-103 shown in fig. 1b, which are not described herein again.

Optionally, after executing 401, the following operations may also be executed:

(11) the method comprises the steps that the mobile terminal detects whether touch operation aiming at the mobile terminal exists within a preset time length;

(12) if not, the mobile terminal closes the display screen of the mobile terminal.

In the embodiment of the application, the preset time duration can be preset and stored in the nonvolatile memory of the mobile terminal. The preset time period may be generally set to less than 10 minutes. For example, the preset time period may be set to 30 seconds, or 1 minute, or 2 minutes, and the embodiment of the present application is not limited. The mobile terminal in the embodiment of the application is a touch-control mobile terminal, and a user can realize human-computer interaction through an interface of the touch-control mobile terminal. If the touch operation aiming at the mobile terminal does not exist within the preset time range, the fact that the user does not operate the mobile phone is indicated, and in order to save the electric quantity of the mobile terminal, the display screen of the mobile terminal can be closed. When the playing content of the mobile terminal is transmitted to the display terminal, the display screen of the mobile terminal does not need to be lightened, so that the electric quantity of the mobile terminal is saved.

The mobile terminal determines 404 a fluctuation range of the ambient light intensity obtained by the light sensor.

And 405, when the fluctuation amplitude is larger than a preset amplitude threshold value, the mobile terminal identifies the scene where the mobile terminal is located.

406, the mobile terminal determines a target backlight brightness corresponding to a scene in which the mobile terminal is located.

And 407, the mobile terminal informs the display terminal to display the playing content at the target backlight brightness.

In the embodiment of the application, the mobile terminal can periodically acquire the ambient light intensity through the light sensor. For example, the mobile terminal may obtain the ambient light intensity every 1 second through the light sensor.

The mobile terminal determining the fluctuation amplitude of the ambient light intensity obtained by the light sensor comprises the following steps: the mobile terminal determines a difference value between the maximum ambient light intensity and the minimum ambient light intensity in the plurality of ambient light intensities acquired within a preset time range, and the difference value is used as a fluctuation range of the ambient light intensity. The preset time range is generally less than 10 minutes, for example, the preset time range may be set to 30 seconds, 45 seconds, 60 seconds, and the like, which is not limited in the embodiment of the present application.

The preset amplitude threshold may be preset and stored in a nonvolatile memory of the mobile terminal, and the preset amplitude threshold may be set to be less than 500lux, for example, may be set to any one of 200lux, 300lux, and 400 lux.

When the fluctuation amplitude is larger than the preset amplitude threshold value, the mobile terminal is considered to be in a scene with larger ambient light change, such as a screen projection scene on a highway and a screen projection scene with larger indoor light change. The mobile terminal can identify the scene where the mobile terminal is located through the camera and the GPS module. Under different scenes, different brightness adjustment strategies can be corresponded. For example, in a screen projection scene on a highway, if the brightness of the display terminal changes rapidly, the user experience may be affected due to rapid changes of the surrounding environment. The corresponding relationship between the ambient light intensity and the backlight brightness in the projection scene on the highway can be set. As shown in table 2, table 2 is a table of correspondence between ambient light intensity and backlight brightness in a projection scene on an expressway, disclosed in the embodiments of the present application.

TABLE 1

As can be seen from table 2, when the ambient light intensities are in different ranges, the corresponding backlight luminances are different. For example, if the ambient light intensity is between 500-.

It can be seen that compared to table 1, the sensitivity of backlight brightness adjustment in table 2 is smaller, and the backlight brightness is not frequently adjusted due to a small change in ambient light transmission, thereby avoiding the situation that the backlight brightness is frequently adjusted in a scene with a large change in ambient light.

Table 2 is a table of correspondence between ambient light intensity and backlight brightness in a screen projection scene on the highway. The corresponding relation table of the ambient light intensity and the backlight brightness in the projection screen scene with large indoor light change can be different from table 2.

In the embodiment of the application, when the display terminal cannot automatically adjust the backlight brightness of the display terminal, the display terminal can control the backlight brightness of the display terminal through the mobile terminal, and the display brightness of the display terminal can be automatically adjusted according to the ambient light intensity collected by the mobile terminal when the display terminal displays the playing content, so that the visual experience of a user watching the display terminal is improved. When the fluctuation range of the ambient light intensity is detected to be large, the scene where the mobile terminal is located can be identified, the backlight brightness is adjusted according to the corresponding relation table of the ambient light intensity corresponding to the scene and the backlight brightness, and the situation that the backlight brightness is frequently adjusted under the scene with large ambient light change is avoided.
