The display device 200 generally has a manual backlight adjustment function and an automatic backlight adjustment function, wherein the manual backlight adjustment function requires a user to adjust a value corresponding to the backlight brightness on the display device 200, so as to control the display device 200 to adjust the backlight brightness; the automatic backlight adjustment function is that the display device 200 senses the brightness of the ambient light through the sensor, and then automatically adjusts the backlight brightness of itself to match the ambient light brightness.
However, in the current display device 200, the manual backlight adjustment function and the automatic backlight adjustment function are independent from each other, and in a case that the automatic backlight adjustment function is turned on, if the user has manually adjusted the backlight brightness, the automatic backlight adjustment function still automatically senses the ambient light to readjust the backlight brightness, so that the operation of the manual adjustment by the user fails, and the use experience of the user is also affected.
Based on the above, the embodiment of the present application provides a display device 200, where the display device 200 may provide a manual backlight adjustment function and an automatic backlight adjustment function for a user, and may also determine whether the automatic backlight adjustment function needs to be turned off according to whether the user uses the manual backlight adjustment function, so that the manual backlight adjustment function and the automatic backlight adjustment function are not affected by each other, and the user experience is ensured.
In the embodiment of the present application, both the manual backlight adjustment function and the automatic backlight adjustment function provided by the display device 200 may be displayed on the same backlight adjustment page. The automatic backlight adjustment function is displayed in an option mode with a switch control, the manual backlight adjustment function is displayed in a backlight brightness control mode, and a currently selected backlight brightness value is displayed on the backlight brightness control.
Referring to fig. 5, fig. 5 illustrates a schematic diagram of a backlight adjustment page on which switch controls may be selected and controlled by a user to enable turning on or off of an automatic backlight adjustment function, according to some embodiments. For example, when the user controls the display device 200 through the control apparatus 100 such as a remote controller, and the user controls the focus to be located on the option of the automatic backlight adjustment function and presses the "confirm" key of the control apparatus 100, the switch control may be controlled to move to the right, thereby starting the automatic backlight adjustment function; or the switch control is controlled to move leftwards, and then the automatic backlight adjusting function is closed.
Referring to fig. 5, the backlight brightness control may adjust the currently displayed backlight brightness value according to the control of the user. For example, the user controls the display apparatus 200 through the control device 100 such as a remote controller, and when the user selects the backlight brightness control, the user may select a value of the target backlight brightness on the numerical bar by pressing left and right direction keys of the control device 100.
As can be seen from the foregoing, in the case that the automatic backlight adjustment function of the display apparatus 200 is turned on, if the user manually adjusts the backlight brightness, the display apparatus 200 still adjusts the backlight brightness by using the automatic backlight adjustment method, and does not adopt the backlight brightness manually adjusted by the user. And under the condition that the automatic backlight adjusting function is not started, the user can randomly adjust the numerical value of the backlight brightness according to the requirement of the user. It can be seen that, in the display apparatus 200, whether the user can manually adjust the backlight brightness depends on whether the automatic backlight adjustment function is turned on, and meanwhile, whether the automatic backlight adjustment function and the manual backlight adjustment function can mutually influence depends on whether the automatic backlight adjustment function is turned on.
Therefore, in this embodiment of the application, the display device 200 needs to detect whether the automatic backlight adjustment function is turned on, and if the automatic backlight adjustment function is turned on, the display device 200 needs to automatically sense the brightness of the ambient light in the environment where the display device 200 is located by using a sensor or other devices, and determine the corresponding target backlight brightness by using the ambient light brightness, and then the display device 200 adjusts the current backlight brightness to the target backlight brightness.
In the display apparatus 200, a uniform standard for correspondence between the ambient light brightness and the backlight brightness of the display apparatus 200 is preset, and the display apparatus 200 may determine the backlight brightness of the corresponding display apparatus 200 using the perceived ambient light brightness according to this uniform standard. The backlight luminance determined by the display device 200 is an actual luminance value, for example, 100cd/m 2 、200cd/m 2 And so on, such a luminance value cannot be directly displayed on the display device 200, and therefore, in the display device 200, an actual luminance value of the backlight luminance determined according to the ambient light luminance is also mapped to a value within 0 to 100, which is a value of the target backlight luminance, for easy adjustment and display.
For example, the display device 200 may perceive the ambient light as 500cd/m 2 Then a backlight brightness of 600cd @, which can be determined in accordance with a corresponding unified standard, is determined in the display device 200m 2 And then mapped into a value a, that is, the target backlight brightness is the value a. The display device 200 may automatically adjust the backlight brightness according to the backlight brightness value a.
Under the condition that the automatic backlight adjusting function is started, if the user considers that the automatically adjusted backlight brightness does not meet the requirement, the user can manually adjust the backlight brightness control to select the target backlight brightness. In order to avoid the mutual influence between the manual backlight adjustment function and the automatic backlight adjustment function, when the user manually adjusts the backlight brightness control, the display device 200 needs to turn off the automatic backlight adjustment function. After the user adjusts the backlight brightness control to select the target backlight brightness, the display device 200 adjusts the current backlight brightness to the target backlight brightness.
In this embodiment, a user needs to input an adjustment instruction to the display device 200 when adjusting the backlight brightness control, and in order to distinguish the adjustment instruction from other adjustment instructions, the adjustment instruction for adjusting the backlight brightness control may be referred to as a first adjustment instruction.
Before manually adjusting the backlight brightness, the user may first control the display device 200 to display a backlight adjustment page, and then adjust the backlight brightness control on the backlight adjustment page, and may also know the value of the currently adjusted backlight brightness while adjusting the backlight brightness control. Therefore, the display device 200 may first detect whether the automatic backlight adjusting function on the backlight adjusting page is turned on, and then receive a first adjusting instruction used by the user to manually adjust the backlight brightness control when the automatic backlight adjusting function on the backlight adjusting page is turned on.
Referring to fig. 6, fig. 6 is a flowchart illustrating a process of manually adjusting the backlight brightness by a user in the display device 200 according to some embodiments, and a controller 250 is disposed in the display device 200, and the controller 250 may control the display device 200 to perform the above-mentioned specific operations. Further, in the process of the user manually adjusting the backlight brightness on the display device 200, the controller 250 may be configured to: whether an automatic backlight adjusting function on a backlight adjusting page is started or not is detected, and whether a first adjusting instruction input by a user is received or not is detected under the condition that the automatic backlight adjusting function is started. And under the condition of receiving the first adjusting instruction, closing the automatic backlight adjusting function, and simultaneously responding to the first adjusting instruction to control the backlight brightness control to display the target backlight brightness. Finally, the current backlight brightness of the display device 200 is adjusted to the target backlight brightness.

Then, the target backlight luminance of the display device 200 that needs to be adjusted is determined according to the luminance of the ambient light.
In the case that the automatic backlight adjusting function is not turned on, the display device 200 does not need to automatically sense the brightness of the ambient light, and the user directly and manually adjusts the backlight brightness. At this time, the display device 200 needs to receive a first adjustment instruction for adjusting the backlight brightness control, which is input by a user, and detect the target backlight brightness corresponding to the current position of the backlight brightness control, where the target backlight brightness is also displayed on the backlight brightness control. Finally, the display device 200 adjusts the current backlight brightness to the target backlight brightness.
Referring to fig. 8, fig. 8 shows another flowchart of a user manually adjusting the backlight brightness in the display device 200 according to some embodiments, and in the process of manually adjusting the backlight brightness by the user, the controller 250 of the display device 200 may be further configured to: under the condition that the automatic backlight adjusting function is not started, whether a first adjusting instruction which is input by a user on a backlight adjusting page and used for adjusting a backlight brightness control is received or not is detected. And under the condition that the first adjusting instruction is received, the backlight brightness control is controlled to display the target backlight brightness in response to the first adjusting instruction.
Under the condition that the automatic backlight adjusting function is not started, if a user does not want to adjust the backlight brightness by himself, the automatic backlight adjusting function can be started actively, namely, a starting instruction is input after an option of the automatic backlight adjusting function is selected on a backlight adjusting page. After the automatic backlight adjustment function is turned on, the display device 200 may continue to sense the ambient light to automatically adjust the backlight brightness, and detect whether the user manually adjusts the backlight brightness again.
For example, as shown in the backlight adjustment page in fig. 5, the switch control of the automatic backlight adjustment function is currently in an off state, the user controls the focus to be located on the option of the automatic backlight adjustment function, and inputs an on instruction, for example, presses an "ok" button of the control device 100, so that the switch control can be controlled to move, and the automatic backlight adjustment function is further turned on. Referring to fig. 9, fig. 9 illustrates a schematic diagram of a backlight adjustment page after an automatic backlight adjustment function is turned on, according to some embodiments.

In some embodiments, to enable the automatic backlight adjustment function to better meet the user's requirements, the display device 200 may also provide the user with a brightness offset control that is applied to the automatic backlight adjustment function, which may be displayed below the automatic backlight adjustment function. The user can adjust the specific brightness offset value by adjusting the brightness offset control, and when the display device 200 uses the automatic backlight adjustment function, the target backlight brightness can be determined jointly by combining the sensed ambient light brightness and the brightness offset value.
Referring to fig. 11, fig. 11 is a schematic diagram illustrating a backlight adjustment page with a brightness shift control according to some embodiments, where a user adjusts the brightness shift control to display a target shift value of 10, and if the display device 200 determines that the corresponding backlight brightness value is 50 according to the sensed ambient light brightness, the display device 200 needs to add a value of 10 to the backlight brightness value 50, so as to finally determine that the target backlight brightness is 60.
Alternatively, referring to fig. 12, fig. 12 is another schematic diagram of a backlight adjustment page with a brightness shift control according to some embodiments, where a user adjusts the brightness shift control to display a target shift value of-10, and if the display device 200 determines that the corresponding backlight brightness value is 50 according to the sensed ambient light brightness, the display device 200 needs to reduce the value by 10 based on the backlight brightness value 50, so as to finally determine that the target backlight brightness is 40.
Referring to fig. 13, fig. 13 is a flow chart illustrating the display device 200 implementing automatic backlight adjustment according to a brightness offset value according to some embodiments, and in the process of implementing automatic backlight adjustment according to the brightness offset value, the controller 250 of the display device 200 may be further configured to: in the case where the automatic backlight adjustment function is turned on, the display 260 is controlled to display a brightness offset control on the backlight adjustment page. And then, responding to a second adjusting instruction which is input by the user on the backlight adjusting page and is used for adjusting the brightness offset control, and controlling the brightness offset control to display the target offset numerical value. Finally, the target backlight brightness of the display device 200 to be adjusted is determined according to the target offset value and the brightness of the ambient light sensed by the display device 200.
In some embodiments, the backlight adjustment page of the display device 200 does not exist separately, but exists in the system settings page. A plurality of function options are arranged on the setting page. User selection of the image option on the settings page may control the display device 200 to display an image settings page. The user selecting the backlight adjustment option on the image setting page may control the display device 200 to display the backlight adjustment page.
Referring to fig. 14, fig. 14 shows a schematic diagram of a setup page having several function options, such as image options, sound options, network options, etc., with different function options also corresponding to different next level setup pages, according to some embodiments.
Referring to fig. 15, fig. 15 illustrates a schematic diagram of an image settings page with several image function options thereon, such as a backlight adjustment option, an image mode option, a color option, a contrast option, etc., according to some embodiments. After the user selects the image option on the setting page as shown in fig. 14, the display device 200 may display an image setting page as shown in fig. 15.
