[0002] Dark mode, also known as dark color mode, is an application mode where text is light and the background is dark.

However, when dark mode is enabled, the interface display quality may be poor. Summary of the Invention

[0030] The backlight optimization method provided in this application can be applied to electronic devices such as mobile phones, tablets, wearable devices, in-vehicle devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs). This application does not impose any restrictions on the specific type of electronic device.

[0031] It should be understood that the sequence number of each step in this embodiment does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of this application embodiment.

[0032] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0033] See Figure 1 This is a schematic diagram illustrating the implementation flow of an information processing method provided in an embodiment of this application, which is applied to an electronic device. Figure 1 As shown, the information processing method may include the following steps:

[0034] Step 101: If the application is adapted to dark mode, obtain the current color gamut mode and current backlight value of the screen.

[0035] The screen displays the application interface. The backlight value is the screen backlight brightness value.

[0036] It should be noted that the application in step 101 can be any application on the electronic device that can adapt to dark mode, or it can be an application selected by the user from the applications on the electronic device that can adapt to dark mode. There is no limitation here.

[0037] Adapting to dark mode refers to adjusting the overall interface style of applications on electronic devices to match the dark mode when it is enabled.

[0038] In one application scenario, a user can enable dark mode in the settings of an electronic device. When an application is launched, if the application supports dark mode, the user can control the application to adapt to dark mode. Alternatively, the user can enable dark mode within the application after it has been launched, and then control the application to adapt to dark mode.

[0039] In one embodiment, when the application is adapted to dark mode, if the application supports backlight optimization, the current color gamut mode and the current backlight value are obtained, and subsequent steps 102 and 103 are executed. This allows for backlight optimization when the application's interface is displayed on the screen, improving the interface display effect in dark mode. If the application does not support backlight optimization, the backlight optimization scheme of this application is not executed.

[0040] Optionally, when users enable dark mode, they can provide an external interface by integrating a software development kit (SDK). When the application supports backlight optimization, it can perform backlight optimization according to the solution of this application, thereby optimizing the interface display effect of the application and achieving a better visual effect.

[0041] Color gamut is a method of color encoding, and also refers to the total number of colors a screen can produce; it can also be understood as a color space area. The higher the color gamut value, the more colors are available within the color space, resulting in a richer color palette.

[0042] Color gamut modes include, but are not limited to, the standard red-green-blue (sRGB) color gamut and wide color gamut. Wide color gamut is an advanced color backlight technology; the international standard defines it as having a color coverage rate of 92% as per the National Television Standards Committee (NTSC). Wide color gamut includes, but is not limited to, the Adobe RGB color gamut and the Digital Cinema Initiatives-Protocol 3 (DIC-P3) color gamut.

[0043] Compared to the sRGB color gamut, the wide color gamut has a higher color gamut value, which can display more colors, making the interface display effect more realistic and avoiding problems such as color distortion and color cast.

[0044] The screen's current backlight value is determined based on the screen refresh rate. The screen obtains the current backlight value every time it refreshes. Optionally, the electronic device can obtain the screen's current color gamut mode and current backlight value from the backlight module.

[0045] Since screen refresh rates are typically high, obtaining the current backlight value every time the screen refreshes minimizes the variation in backlight optimization, resulting in a smoother visual effect and preventing screen flickering when the backlight value changes drastically.

[0046] Step 102: Determine the type of backlight region where the current backlight value is located.

[0047] The backlight area types include low backlight area and high backlight area. The backlight area can be understood as the backlight range.

[0048] If the screen's current backlight value is in either the low or high backlight range, the interface display is poor. For example, in a low backlight range, the interface clarity is poor; in a high backlight range, the colors are too prominent, which can cause eye strain. Therefore, when the screen's current backlight value is in either the low or high backlight range, backlight optimization is needed to improve the interface display in dark mode, enhance the user's visual experience, and make the interface display more pleasing to the human eye. If the screen's current backlight value is neither in the low nor high backlight range, the interface display is good, and no backlight optimization is needed.

[0049] For any screen, its maximum and minimum backlight values ​​are fixed, determined by the screen's physical characteristics and cannot be changed. These values ​​are set by the manufacturer at the factory. Therefore, based on the screen's maximum and minimum backlight values ​​and the interface display effect at different backlight values, low-backlight and high-backlight areas can be defined. For example, if the screen's maximum backlight value is 100 nits and its minimum backlight value is 2 nits, and the interface display effect is poor when the screen's backlight value is less than or equal to 20 nits or greater than 80 nits (e.g., poor clarity when the backlight value is less than or equal to 20 nits, and glaring when the backlight value is greater than 80 nits), then the low-backlight area can be defined as greater than or equal to 2 nits and less than or equal to 20 nits, and the high-backlight area as greater than 80 nits and less than or equal to 100 nits.

[0050] Step 103: Optimize the screen backlight based on the backlight area type, color gamut mode, and backlight value of the current backlight value.

[0051] Since both color gamut mode and screen backlight value affect the interface display effect, and the interface display effect is different under different backlight area types, the screen backlight can be optimized based on the backlight area type, current color gamut mode and current backlight value, thereby improving the interface display effect on the screen in dark mode, improving the user visual experience and making the interface display more in line with human eye perception.

[0052] In this embodiment, when the application is adapted to dark mode, the current color gamut mode and current backlight value of the screen can be obtained, and the type of backlight area where the current backlight value is located can be determined. Since the interface display effect varies in different backlight areas, and both the color gamut mode and the backlight value affect the interface display effect, this application can optimize the screen backlight based on the type of backlight area where the current backlight value is located, the current color gamut mode, and the current backlight value, thereby improving the interface display effect in dark mode.

[0053] See Figure 2 This is a schematic diagram illustrating the implementation process of a backlight optimization method provided in another embodiment of this application, which is applied to electronic devices. Figure 2 As shown, the backlight optimization method may include the following steps:

[0054] Step 201: If the application is adapted to dark mode, obtain the current color gamut mode and current backlight value of the screen.

[0055] This step is the same as step 101. For details, please refer to the relevant description of step 101. It will not be repeated here.

[0056] Step 202: Determine the type of backlight region where the current backlight value is located.

[0057] This step is the same as step 102, and you can refer to the relevant description of step 102 for details, which will not be repeated here.

[0058] Step 203: Determine the target color gamut mode based on the current color gamut mode.

[0059] The target color gamut mode has a color gamut value greater than the current color gamut mode. In other words, the target color gamut mode is a color gamut mode with a color gamut value greater than the current color gamut mode. For example, if the current color gamut mode is sRGB, then the target color gamut mode can be a wide color gamut.

[0060] Step 204: Optimize the screen backlight based on the backlight region type, target color gamut mode, and current backlight value.

[0061] Since both color gamut mode and screen backlight value affect the interface display effect, and the interface display effect is different under different backlight area types and different color gamut modes, the screen backlight can be optimized based on the backlight area type, target color gamut mode and current backlight value, thereby improving the interface display effect on the screen in dark mode, improving the user visual experience and making the interface display more in line with human eye perception.

[0062] In one optional embodiment, backlight optimization of the screen is performed based on the backlight region type, target color gamut mode, and current backlight value, including:

[0063] Determine whether the application supports the target color gamut mode and obtain the determination result;

[0064] Based on the type of backlight area where the current backlight value is located, the judgment result, and the current backlight value, the screen backlight is optimized.

[0065] The above judgment results include whether the application supports the target color gamut mode or not.

[0066] Electronic devices can determine whether to optimize backlight by switching color gamut modes based on the judgment result. Different judgment results result in different interface display effects. Therefore, based on the backlight area type where the current backlight value is located, the judgment result, and the current backlight value, the screen can be optimized for backlight.

[0067] Whether an application supports the target color gamut mode can be pre-set. For example, if the application supports the target color gamut mode, its identifier can be pre-written into the application's attribute information. When implementing the solution of this application, if the identifier of the target color gamut mode is read from the application's attribute information, it is determined that the application supports the target color gamut mode; if the identifier of the target color gamut mode is not read from the application's attribute information, it is determined that the application does not support the target color gamut mode. The identifier of the target color gamut mode indicates the uniqueness of the target color gamut mode; different color gamut modes have different identifiers. For example, the identifier of the target color gamut mode can be the name of the target color gamut mode.

[0068] Of course, it is understandable that the screen can also be backlit optimized in other ways based on the type of backlight area where the current backlight value is located, the judgment result and the current backlight value, and this application does not limit this.

[0069] In one optional embodiment, backlight optimization of the screen is performed based on the backlight region type where the current backlight value is located, the judgment result, and the current backlight value, including:

[0070] If the determination result is that the application supports the target color gamut mode, then the current color gamut mode is switched to the target color gamut mode. In the target color gamut mode, based on the backlight area type where the current backlight value is located and the current backlight value, the first backlight value is determined and the current backlight value is adjusted to the first backlight value.

[0071] If the determination result is that the application does not support the target color gamut mode, then under the current color gamut mode, based on the backlight area type where the current backlight value is located and the current backlight value, a second backlight value is determined, and the current backlight value is adjusted to the second backlight value, which is different from the first backlight value.

[0072] The aforementioned first backlight value can refer to a backlight value that, compared to the current backlight value, can improve the interface display effect under the target color gamut mode. For example, under the target color gamut mode, when the current backlight value is in a low backlight area, the first backlight value is greater than the current backlight value; under the current color gamut mode, when the current backlight value is in a low backlight area, the second backlight value is greater than the current backlight value, and the second backlight value is greater than the first backlight value. Under the above two color gamut modes, by adjusting the screen's backlight value, the screen backlight brightness can be increased, thereby improving the interface display effect.

[0073] Because the target color gamut mode has a higher color gamut value, switching the screen's current color gamut mode to the target color gamut mode allows the screen to display more colors, enhancing the interface display and achieving a better visual effect, thereby optimizing the screen's backlight. Therefore, the adjustment scheme for the current backlight value should differ depending on whether the color gamut mode is switched or not. Furthermore, since different backlight areas have different effects on the interface display effect, adjusting the screen's backlight value based on the color gamut mode, backlight area type, and current backlight value can more accurately optimize the backlight and further improve the interface display effect in dark mode.

[0074] Of course, it is understandable that the screen can also be backlit optimized in other ways based on the type of backlight area where the current backlight value is located, the judgment result and the current backlight value, and this application does not limit this.

[0075] In an optional embodiment, under the target color gamut mode, determining a first backlight value based on the backlight region type where the current backlight value is located and the current backlight value includes:

[0076] In the target color gamut mode, the first adjustment coefficient is determined based on the type of backlight region where the current backlight value is located;

[0077] The first backlight value is determined based on the first adjustment coefficient and the current backlight value;

[0078] In the current color gamut mode, based on the backlight region type where the current backlight value is located and the current backlight value, a second backlight value is determined, including:

[0079] In the current color gamut mode, a second adjustment coefficient is determined based on the type of backlight region where the current backlight value is located. The second adjustment coefficient is different from the first adjustment coefficient.

[0080] The second backlight value is determined based on the second adjustment factor and the current backlight value.

[0081] The first and second adjustment coefficients are used to adjust the current backlight value. Multiplying the current backlight value by the first adjustment coefficient yields the first backlight value. Multiplying the current backlight value by the second adjustment coefficient yields the second backlight value. For either the first or second adjustment coefficient, if the adjustment coefficient is less than 1, the screen backlight brightness can be reduced; if the adjustment coefficient is greater than 1, the screen backlight brightness can be increased.

[0082] Because the interface display effect varies under different color gamut modes and also differs depending on the backlight area, the adjustment coefficients differ for each color gamut mode and backlight area type. Therefore, under different color gamut modes, the adjustment coefficient can be determined more accurately based on the backlight area type where the current backlight value is located, thereby adjusting the screen's backlight brightness more precisely and improving the interface display effect.

[0083] Of course, it is understood that the first backlight value and the second backlight value can also be determined in other ways based on the type of backlight area where the current backlight value is located and the current backlight value, and this application does not limit this.

[0084] In an optional embodiment, under the target color gamut mode, a first adjustment coefficient is determined based on the type of backlight region where the current backlight value is located, including:

[0085] In the target color gamut mode, if the backlight area where the current backlight value is located is a low backlight area, then the first adjustment coefficient is determined to be the third adjustment coefficient, and the third adjustment coefficient is greater than 1.

[0086] In the target color gamut mode, if the backlight area type where the current backlight value is located is a high backlight area, then the first adjustment coefficient is determined to be the fourth adjustment coefficient, and the fourth adjustment coefficient is greater than zero and less than 1.

[0087] In the current color gamut mode, based on the type of backlight region where the current backlight value is located, a second adjustment coefficient is determined, including:

[0088] In the current color gamut mode, if the backlight area where the current backlight value is located is a low backlight area, then the second adjustment coefficient is determined to be the fifth adjustment coefficient, and the fifth adjustment coefficient is greater than the third adjustment coefficient.

[0089] In the current color gamut mode, if the backlight area where the current backlight value is located is a high backlight area, then the second adjustment coefficient is determined to be the sixth adjustment coefficient, and the sixth adjustment coefficient is greater than the fourth adjustment coefficient.

[0090] In dark mode, the interface is less clear when the current backlight value is in a low backlight area. Therefore, you can increase the current backlight value to brighten the screen backlight and improve the clarity.

[0091] Since the target color gamut mode has a higher color gamut value and can display more colors, when the current backlight value is in the low backlight area, the target color gamut mode does not require much increase in screen backlight brightness to improve the interface display effect compared to the current color gamut mode. Therefore, the fifth adjustment coefficient can be set to be greater than the third adjustment coefficient.

[0092] In dark mode, when the current backlight value is in the high backlight area, the color contrast is large, which can easily cause glare. Therefore, you can reduce the current brightness value to reduce the glare caused by the color contrast.

[0093] When the current brightness value is in the high backlight area, after switching the current color gamut mode of the screen to the target color gamut mode, the screen can display more colors and the colors are more vivid. Therefore, in order to reduce the difference between the same color, compared with the current color gamut mode with a lower color gamut value, the reduction of screen backlight brightness can be increased, that is, the second adjustment coefficient is set to be greater than the first adjustment coefficient.

[0094] For example, the third adjustment factor is 1.2, the fifth adjustment factor is 1.5, the fourth adjustment factor is 0.7, and the sixth adjustment factor is 0.8. Optionally, the third, fifth, fourth, and sixth adjustment factors can be preset according to actual needs.

[0095] Of course, it is understandable that the adjustment coefficient can also be determined in other ways based on the type of backlight area where the current backlight value is located, and this application does not limit this.

[0096] Optionally, when the application supports the target color gamut mode, the processor in the electronic device can send a switching instruction carrying a target color gamut mode identifier to the backlight module. This switching instruction is used to support switching the current color gamut mode to the target color gamut mode. The backlight module sends the switching instruction to the screen driver. After receiving the switching instruction, the screen driver switches the current color gamut mode to the target color gamut mode.

[0097] After obtaining the first backlight value or the second backlight value, the processor in the electronic device can send the first backlight value or the second backlight value to the backlight module, the backlight module sends the first backlight value or the second backlight value to the screen driver, and the screen driver adjusts the screen backlight brightness based on the received first backlight value or second backlight value.

[0098] In this embodiment, when the application is adapted to dark mode, the current color gamut mode and current backlight value of the screen can be obtained, and the type of backlight area where the current backlight value is located can be determined. Based on the current color gamut mode, the target color gamut mode is determined. Since the interface display effect is different in different backlight areas, the interface display effect is also different in different color gamut modes. Therefore, this application can optimize the screen backlight based on the type of backlight area where the current backlight value is located, the target color gamut mode, and the current backlight value, thereby improving the interface display effect in dark mode.
