With the continuous upgrade of the display device 200, the current display device 200 has emerged many new functions in displaying, so as to provide a more professional display effect for the user. As one of the most intuitive parameters affecting the display effect, the backlight adjustment has been performed by "automatic backlight adjustment" or the like. When the "automatic backlight adjustment" function of the display device 200 is turned on, the display device 200 may automatically adjust the current backlight brightness to the target backlight brightness corresponding to the ambient brightness according to the sensed ambient brightness.

However, the "automatic backlight adjustment" function provides the user with the brightness parameter that has been configured by the technician, and the user cannot realize the autonomous dynamic adjustment of the backlight brightness or the screen brightness based on the ambient brightness according to the own brightness preference, which makes the display device 200 difficult to meet the user's needs and eventually affects the user experience.

Based on the above, the present embodiment provides a display apparatus 200, where the display apparatus 200 can communicate with a control device 100 such as a remote controller or a virtual remote controller, and further receive a control instruction issued by a user through operation of the control device 100.

The display device 200 may provide a corresponding relationship between the adjustable ambient brightness and the backlight brightness for a user, and after the brightness corresponding relationship is set by the user, the display device 200 automatically detects the ambient brightness of the current environment of the display device 200 under the condition that the automatic backlight adjustment function is turned on, which may be specifically referred to as target ambient brightness. Then, the display device 200 finds the target ambient brightness in the brightness correspondence set by the user, and determines the target backlight brightness corresponding to the target ambient brightness. The target backlight brightness is the backlight brightness that the user previously sets to desire the display device 200 to display at the target ambient brightness. Finally, the display device 200 adjusts the current backlight brightness by using the determined target backlight brightness, so that the adjusted backlight brightness meets the user's requirement.

Fig. 5 illustrates a schematic diagram of the display device 200 adjusting the backlight brightness according to some embodiments, and as shown in fig. 5, the display device 200 mainly responds to various instructions by the controller 250 therein, and simultaneously performs the corresponding control operation. The controller 250 of the display apparatus 200 may be configured to: first, in a case where the automatic backlight adjustment function is turned on, a target ambient brightness of an environment in which the display device 200 is located is detected. And then, determining the target backlight brightness corresponding to the target environment brightness by using the brightness corresponding relation. Finally, the current backlight brightness of the display device 200 is adjusted using the target backlight brightness.

In some embodiments, the display device 200 may also provide a brightness detail setting page for the user, where the brightness correspondence may be adjusted. The brightness detail setting page displays the corresponding relation between the ambient brightness and the backlight brightness, such as a broken line relation, a curve relation, and the like. Generally, the brightness correspondence relationship may be established in a two-dimensional coordinate system, where the abscissa represents ambient brightness, and the ordinate represents backlight brightness, and the backlight brightness corresponding to each ambient brightness may be selected by a user to correspondingly display different brightness values.

Fig. 6 illustrates a schematic diagram of a brightness detail setting page according to some embodiments, as shown in fig. 6, on the brightness detail setting page, each cell on the horizontal axis represents 10 values, the horizontal axis represents the ambient brightness from dark to light from left to right, and the vertical axis represents the backlight brightness from dark to light from bottom to top. In the corresponding relationship, the environment brightness value of the abscissa is the representation value after the real environment brightness mapping, and the backlight brightness value of the ordinate is also the representation value after the real backlight brightness mapping. And movable positioning controls are respectively arranged on the longitudinal lines corresponding to the ambient brightness, and the positioning controls on each longitudinal line can only move up and down in the longitudinal direction. The user can control the positioning control to move longitudinally, and further adjust the backlight brightness corresponding to certain ambient brightness.

In the process of setting the brightness correspondence by the user, the user may first input a first page display instruction to the display device 200, and control the display device 200 to display a brightness detail setting page. Then, the operation of moving the positioning control on the vertical line corresponding to the target ambient brightness on the brightness detail setting page by the user may be regarded as inputting a first setting instruction to the display device 200, and controlling the display device 200 to set the target backlight brightness corresponding to the target ambient brightness as the backlight brightness corresponding to the position of the positioning control.

Fig. 7 illustrates a schematic diagram of the display apparatus 200 setting the brightness correspondence according to some embodiments, and as shown in fig. 7, in the above-mentioned process of setting the brightness correspondence by the user, the controller 250 of the display apparatus 200 may be configured to: first, in response to a first page display instruction input by the user, the display 260 is controlled to display a brightness detail setting page. And then, responding to a first setting instruction input by the user on the brightness detail setting page, and setting the backlight brightness corresponding to the target environment brightness selected by the user as the target backlight brightness.

As described above, the display apparatus 200 needs to automatically detect the ambient brightness in a case where the automatic backlight adjustment function is turned on, in other words, if the automatic backlight adjustment function is not turned on, the display apparatus 200 does not automatically adjust the backlight brightness according to the brightness correspondence relationship even if the brightness correspondence relationship is previously set by the user. Therefore, before the display apparatus 200 is required to automatically adjust the backlight brightness, the user also needs to control the display apparatus 200 to turn on the automatic backlight adjustment function.

In some embodiments, the switch for turning on the automatic backlight adjustment function is disposed on the brightness detection page of the display device 200, and the display device 200 needs to display an image setting page of a previous stage before displaying the brightness detection page, where a brightness detection option is disposed on the image setting page, and the display device 200 can be controlled to display the brightness detection page by selecting the brightness detection option on the image setting page by the user.

FIG. 9 illustrates a schematic diagram of a brightness detection page with an open option and a close option displayed thereon, as shown in FIG. 9, in accordance with some embodiments. If the user selects the on option on the brightness detection page, the display device 200 immediately turns on the automatic backlight adjustment function while starting to detect the ambient brightness. If the user selects the close option on the brightness detection page, the display device 200 closes the automatic backlight adjustment function, and does not automatically adjust the backlight brightness according to the ambient brightness. And, on the image setting page as shown in fig. 8, the position of the brightness detection option will also show whether the current automatic backlight adjustment function is turned on, so that the user can clearly understand the situation of the function.

In the process of turning on or turning off the automatic backlight adjustment function, the user may input a second page display instruction to the display device 200 first, and control the display device 200 to display an image setting page; then, the user selects a brightness detection option on the image setting page, and further inputs a first selection instruction to the display device 200, and controls the display device 200 to display the brightness detection page; finally, the user selects the brightness detection starting option on the brightness detection page, and further inputs a second selection instruction to the display device 200, and controls the display device 200 to start the automatic backlight adjustment function. Or, the user selects the brightness detection closing option on the brightness detection page, and further inputs a third selection instruction to the display device 200, so as to control the display device 200 to close the automatic backlight adjustment function.

Then, in response to a first selection instruction for selecting the brightness detection option input by the user on the image setting page, the display 260 is controlled to display the brightness detection page. And finally, responding to a second selection instruction which is input by the user on the brightness detection page and used for selecting the brightness detection starting option, and controlling the automatic backlight adjustment function to be started.
