[0053] In the embodiment of the present application, the computer device 100 and the target display device may be the same device, or the computer device 100 and the target display device may be different devices, and the target display device may be any device with a display function, such as a television, a computer, a projector, etc. It is understandable that when the computer device 100 and the target display device are the same device, the target display device can use the backlight adjustment method provided in the embodiment of the present application to adjust its own backlight current, thereby reducing the overall power consumption of the target display device and alleviating the temperature rise problem of the target display device.

[0058] It should be noted that Figure 1 The scene diagram of the backlight adjustment system shown is merely an example. The backlight adjustment system and scene described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the backlight adjustment system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is equally applicable to similar technical problems.

[0059] First, a backlight adjustment method is provided in an embodiment of the present application, and the executor of the backlight adjustment method is a backlight adjustment device, and the backlight adjustment device is applied to a computer device. The backlight adjustment method includes: obtaining current graphic effect information of a target display device; based on the current graphic effect information, determining whether the current graphic effect mode of the target display device is a target graphic effect mode; if the current graphic effect mode is not the target graphic effect mode, adjusting the backlight current of the target display device based on the current picture APL value.

[0060] like Figure 2 FIG. 2 is a flow chart of an embodiment of a backlight adjustment method in an embodiment of the present application. The backlight adjustment method may include the following steps S201 to S203, which are as follows:

[0061] Step S201: Obtain current image effect information of the target display device.

[0062] In an embodiment of the present application, the current graphic effect information is a global variable that characterizes the current graphic effect mode of the target display device. The current graphic effect mode of the target display device can be determined based on the current graphic effect information of the target display device. The graphic effect mode refers to a series of parameter settings preset in the display device. For example, the graphic effect mode of the target display device includes a bright graphic effect mode, a standard graphic effect mode, a dynamic graphic effect mode, a game graphic effect mode, and a custom graphic effect mode. The current graphic effect information is "1", which indicates that the current graphic effect mode is a bright graphic effect mode. The current graphic effect information is "2", which indicates that the current graphic effect mode is a standard graphic effect mode. The current graphic effect information is "3", which indicates that the current graphic effect mode is a dynamic graphic effect mode. The current graphic effect information is "4", which indicates that the current graphic effect mode is a game graphic effect mode. The current graphic effect information is "5", which indicates that the current graphic effect mode is a custom graphic effect mode.

[0063] Step S202: Based on the current graphic effect information, determine whether the current graphic effect mode of the target display device is the target graphic effect mode.

[0064] In an embodiment of the present application, the graphic effect mode of the target display device includes a bright graphic effect mode, and the target graphic effect mode is a bright graphic effect mode. Considering that compressing the backlight current of the target display device in the bright graphic effect mode cannot meet the user's requirement for bright picture quality, when the backlight is adjusted in this embodiment, the current graphic effect information of the target display device is first obtained, and based on the current graphic effect information, it is determined whether the current graphic effect mode of the target display device is the bright graphic effect mode. When the current graphic effect mode is not the bright graphic effect mode, the backlight current of the target display device is compressed, which can not only reduce the power consumption and temperature rise of the target display device, but also meet the user's requirement for bright picture quality.

[0065] Optionally, when determining whether the current image effect mode of the target display device is the target image effect mode based on the current image effect information, it can be determined whether the current image effect information is preset information, and if the current image effect information is preset information, the current image effect mode of the target display device is determined to be the target image effect mode. For example, if the current image effect information is 1, it is determined that the current image effect mode of the target display device is a bright image effect mode.

[0066] Optionally, when determining whether the current graphic effect mode of the target display device is the target graphic effect mode based on the current graphic effect information, the current graphic effect mode of the target display device can also be determined based on the current graphic effect information and the first associated information, and then it is determined whether the current graphic effect mode is the target graphic effect mode. Among them, the first associated information represents the correspondence between the graphic effect information and the graphic effect mode. For example, the graphic effect information of "1", "2", "3", "4" and "5" respectively corresponds to the bright graphic effect mode, the standard graphic effect mode, the dynamic graphic effect mode, the game graphic effect mode and the custom graphic effect mode. If the current graphic effect information is "1", it is determined that the current graphic effect mode is the bright graphic effect mode. If the current graphic effect information is "2", it is determined that the current graphic effect mode is the standard graphic effect mode.

[0067] Step S203: If the current image effect mode is not the target image effect mode, the backlight current of the target display device is adjusted based on the current picture APL value.

[0068] In the embodiment of the present application, the APL (average pixel level, average pixel brightness level, APL for short) value of the current screen refers to the average pixel brightness level of the current screen, that is, the average brightness of the screen. Based on the APL value of the current screen, it can be determined whether the current screen is a full white screen. The backlight current refers to the current supplied to the backlight source in the backlight module. The backlight module is usually composed of LEDs or fluorescent lamps. By controlling the size of the backlight current, the brightness of the display screen can be adjusted. In a specific embodiment, the backlight current can be the maximum backlight current. The maximum backlight current refers to the maximum current value that the backlight module can withstand. By reducing the maximum backlight current, the screen heat can be effectively reduced, power consumption can be reduced, service life can be extended, and the adjustable range of brightness can be increased.

[0069] In the embodiment of the present application, when the current image effect mode is not the target image effect mode, the backlight current of the target display device is adjusted based on the APL value of the current screen, which can not only reduce the power consumption of the entire target display device and alleviate the temperature rise problem of the target display device, but also ensure the display effect of the target display device in the target image effect mode and the full white screen.

[0070] In a specific embodiment, referring to Figure 3As shown, in the above step S202, based on the current graphic effect information, determining whether the current graphic effect mode of the target display device is the target graphic effect mode may include steps S301 to S303, which are specifically as follows:

[0071] Step S301: Match the current graphic effect information with the first reference information.

[0072] In an embodiment of the present application, the first benchmark information is pre-set reference information for measuring whether the current graphic effect mode is the target graphic effect mode. For example, the first benchmark information can be set to "1", "2", "3", etc. The first benchmark information can also be set to "bright", etc.

[0073] Step S302: If the current graphic effect information matches the first reference information, determine that the current graphic effect mode of the target display device is the target graphic effect mode.

[0074] In the embodiment of the present application, the current graphic effect information matches the first reference information, which means that the current graphic effect information and the first reference information are the same information, or the current graphic effect information matches the first reference information, which means that the current graphic effect information and the first reference information are semantically similar. For example, if the current graphic effect information is "1" and the first reference information is also "1", it is determined that the current graphic effect information matches the first reference information, and the current graphic effect mode of the target display device is the bright graphic effect mode.

[0075] Step S303: If the current graphic effect information does not match the first reference information, determine that the current graphic effect mode of the target display device is not the target graphic effect mode.

[0076] In the embodiment of the present application, the current graphic effect information does not match the first reference information, which may be information that the current graphic effect information and the first reference information are different, or the current graphic effect information does not match the first reference information, which may be semantically dissimilar to the first reference information. For example, if the current graphic effect information is "0" and the first reference information is "1", it is determined that the current graphic effect information does not match the first reference information, and the current graphic effect mode of the target display device is not a bright graphic effect mode.

[0077] In a specific embodiment, referring to Figure 4 As shown, the adjustment process of the backlight current of the target display device based on the APL value of the current picture in the above step S203 may include steps S401 to S402, which are specifically as follows:

[0078] Step S401: If the APL value of the current picture is less than the APL threshold, compress the backlight current of the target display device.

[0079] In the embodiment of the present application, the APL threshold is a preset threshold used to measure whether the current picture is a completely white picture. The APL threshold varies with the APL value of the current picture. For example, when the APL value of the current picture is a grayscale value, the APL threshold is also a grayscale value. When the APL value of the current picture is a proportion of a bright area in the current picture, the APL threshold is also a proportion value. Optionally, the APL threshold can be 255, 100%, etc.

[0080] In a specific embodiment, the backlight current after compression and the backlight current before compression satisfy the following formula: , represents the backlight current before compression, D represents the backlight current after compression, represents the second ratio value, It can be set according to actual needs. In a specific embodiment, , optionally, , thus ensuring that the backlight current of the target display device in different modes changes within a reasonable range.

[0081] Optionally, if the APL value of the current screen is less than the APL threshold, indicating that the current screen is not a full white screen, the backlight current of the target display device can be directly compressed, thereby reducing the power consumption of the entire target display device and alleviating the temperature rise problem of the target display device. For example, referring to Table 1, the APL threshold is 100%. If the APL value of the current screen is less than 100% and the current image effect mode is the standard image effect mode, the backlight current of the target display device is reduced from 131.25mA to 119.375mA.

[0082] Table 1 Backlight current and brightness corresponding to different test conditions

[0083]

[0084] In a specific embodiment, the step of compressing the backlight current of the target display device specifically includes: obtaining the original backlight value corresponding to each point in the backlight curve of the target display device; calculating and processing the original backlight value and the first ratio value to obtain the target backlight value corresponding to each point; adjusting the original backlight value corresponding to each point in the backlight curve to the target backlight value to achieve the compression of the backlight current. For example, adjusting the backlight value of each point in the backlight curve to 90% of the original backlight value can reduce the maximum backlight current from 130mA to about 120mA, and reduce the screen brightness by about 6%.

[0085] In the embodiment of the present application, the step of calculating and processing the original backlight value and the first ratio value to obtain the target backlight value corresponding to each point specifically includes: multiplying the original backlight value and the first ratio value to obtain the target backlight value corresponding to each point. Optionally, the calculation process of the target backlight value can be expressed as: , Indicates the target backlight value, Represents the original backlight value, Represents the first ratio value. The first ratio value can be set according to actual needs. In a specific embodiment, , optionally, .

[0086] Step S402: If the APL value of the current picture is greater than or equal to the APL threshold, the backlight current of the target display device is kept unchanged.

[0087] In a specific embodiment, if the APL value of the current screen is greater than or equal to the APL threshold, indicating that the current screen is a full white screen, the backlight current of the target display device is kept unchanged, so that the display effect of the full white screen of the target display device can be guaranteed on the basis of reducing the power consumption of the entire target display device and alleviating the temperature rise problem of the target display device. For example, referring to Table 1, the APL threshold is 100%, if the APL value of the current screen is equal to 100%, the backlight current of the target display device is kept unchanged at 131.25mA.

[0088] In a specific implementation, after determining whether the current image effect mode of the target display device is the target image effect mode based on the current image effect information in the above step S202, the following steps are included: if the current image effect mode is the target image effect mode, the backlight current of the target display device is kept unchanged, so that the display effect of the target image effect mode can be guaranteed on the basis of reducing the power consumption of the entire target display device and alleviating the temperature rise problem of the target display device. For example, continuing to refer to Table 1, if the current image effect mode is the bright image effect mode, the backlight current of the target display device is kept unchanged at 131.25mA.

[0089] In a specific implementation, before obtaining the current graphic effect information of the target display device in the above step S201, it may include: obtaining backlight information of the target display device; if the backlight information does not match the second reference information, keeping the backlight current of the target display device unchanged.

[0090] In an embodiment of the present application, the backlight information may be a dynamic backlight version number of the target display device, and the second reference information may be pre-set reference information for measuring whether the target display device is in energy-saving mode. If the backlight information matches the second reference information, indicating that the target display device is in energy-saving mode, the computer device executes the above steps S201 to S203, thereby reducing the overall power consumption of the target display device and alleviating the temperature rise problem of the target display device. On the contrary, if the backlight information does not match the second reference information, indicating that the target display device is not in energy-saving mode, the backlight current of the target display device is kept unchanged, so that the backlight current of the target display device can be adjusted according to user needs, thereby improving the flexibility of backlight adjustment.

[0091] Furthermore, the backlight information and the second reference information may match each other when the backlight information and the second reference information are identical, or may match each other when the backlight information and the second reference information are semantically similar. For example, if the backlight information is "50" and the second reference information is also "50", it is determined that the backlight information and the second reference information match each other; if the backlight information is "60" and the second reference information is also "50", it is determined that the backlight information and the second reference information do not match each other.

[0092] In a specific embodiment, after acquiring the backlight information of the target display device, the following steps are included: if the backlight information matches the second reference information, determining whether the target display device is in a target state; if the target display device is in the target state, keeping the backlight current of the target display device unchanged.

[0093] In the embodiment of the present application, if the backlight information matches the second reference information, that is, the energy-saving mode of the target display device is turned on, it is determined whether the target display device is in the target state. If the target display device is in the target state, the backlight current of the target display device is kept unchanged, so as to ensure that the backlight current of the target display device remains unchanged in the target state. For example, if the target state is the debugging state, if the energy-saving mode of the target display device is turned on, it is determined whether the target display device is in the debugging state. If the target display device is in the debugging state, the backlight current of the target display device is kept unchanged; on the contrary, if the target display device is not in the debugging state, the computer device executes the above steps S201 to S203, so as to reduce the power consumption of the entire target display device and alleviate the temperature rise problem of the target display device.

[0094] In order to better implement the backlight adjustment method in the embodiment of the present application, based on the backlight adjustment method, a backlight adjustment device is also provided in the embodiment of the present application, such as Figure 5 As shown, the backlight adjustment device 600 includes:

[0095] The information acquisition module 610 is used to acquire the current image effect information of the target display device;

[0096] A mode determination module 620 is used to determine whether a current image effect mode of a target display device is a target image effect mode based on the current image effect information;

[0097] The backlight adjustment module 630 is used to adjust the backlight current of the target display device based on the current picture APL value if the current image effect mode is not the target image effect mode.

[0098] In an embodiment of the present application, based on the current graphic effect information, it is determined whether the current graphic effect mode of the target display device is the target graphic effect mode. If the current graphic effect mode is not the target graphic effect mode, the backlight current of the target display device is adjusted based on the current screen APL value. This can not only reduce the overall power consumption of the target display device and alleviate the temperature rise problem of the target display device, but also ensure the display effect of the target display device in the target graphic effect mode and the full-white screen.

[0099] In some embodiments of the present application, the mode determination module 620 determines whether the current image effect mode of the target display device is the target image effect mode based on the current image effect information, including:

[0100] Matching the current image effect information with the first reference information;

[0101] If the current graphic effect information matches the first reference information, determining that the current graphic effect mode of the target display device is the target graphic effect mode;

[0102] If the current graphic effect information does not match the first reference information, it is determined that the current graphic effect mode of the target display device is not the target graphic effect mode.

[0103] In some embodiments of the present application, the backlight adjustment module 630 adjusts the backlight current of the target display device based on the current picture APL value, including:

[0104] If the APL value of the current screen is less than the APL threshold, the backlight current of the target display device is compressed;

[0105] If the APL value of the current screen is greater than or equal to the APL threshold, the backlight current of the target display device is kept unchanged.

[0106] In some embodiments of the present application, the backlight adjustment module 630 compresses the backlight current of the target display device, including:

[0107] Obtain the original curve value corresponding to each point in the backlight curve of the target display device;

[0108] Calculate and process the original curve value and the first proportional value to obtain the target curve value corresponding to each point;
