Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the related art, a display screen of a terminal is a device which is most touched by a daily user when in use. To facilitate user usage, a variety of display modes are provided, such as: standard mode, excited luminance mode, etc. The display provides backlight brightness that is the same as the display brightness of the display screen. In the standard mode, the display brightness of the display screen includes a first brightness. The first brightness may be expressed as a maximum display brightness that can be provided in the standard mode. The excited brightness mode includes a second brightness, which may be expressed as an excited brightness and is a fixed height preset when the display screen leaves a factory. When the excitation mode is started, the display brightness of the display screen is directly increased to the second brightness, so that the display screen can still clearly display the content in the display screen under strong light. The second brightness is higher than the first brightness, and a certain brightness difference exists. In one implementation scenario, as shown in FIG. 1. When the brightness intensity of the received external environment is too strong or the terminal detects that the brightness value of the external environment intensity is too high under the condition of direct sunlight, the excitation brightness mode is started, and the current backlight brightness of the display screen is improved to the excitation brightness mode. The excitation brightness cannot be adjusted due to the hardware limitations of the terminal itself. When the display screen is used, when the first brightness is adjusted to the second brightness, jumping can occur between the first brightness and the second brightness, so that the display brightness of the display screen is suddenly improved, the use experience of a user is influenced, and the eyesight is easily damaged.
The present disclosure provides a brightness adjustment method capable of combining software and hardware of a terminal. When the excitation brightness mode is adopted, the masking layer is called, and when the backlight brightness of the masking layer is kept at the second brightness, the display brightness of the display screen can be adjusted by adjusting the transparency of the masking layer, so that the widening of the brightness interval displayed by the display screen of the terminal is facilitated. The display brightness of the display screen can be adjusted between the first brightness and the second brightness according to the intensity of the external environment brightness, poor experience brought to a user by display brightness jumping is reduced, use experience of the user is improved, and visual fatigue of the user in use is reduced.
The terminal may include: terminals with display screens such as mobile phones, tablets and notebooks; or a terminal capable of playing video, which is not limited in this disclosure.
Fig. 2 is a flowchart illustrating a brightness adjustment method according to an exemplary embodiment, where as shown in fig. 2, the brightness adjustment method 10 is applied to a terminal, the terminal includes a display screen, and the brightness adjustment method 10 includes the following steps S11 to S12.
In step S11, the current display brightness of the display screen is determined.
In the embodiment of the disclosure, the display mode of the terminal started at present can be determined through the current display brightness of the display screen, and then the display brightness can be adjusted in a targeted manner when being adjusted. The display range of the display screen for different display modes is different. For example: when the current display brightness of the display screen is lower than or equal to 500 nits, the terminal is in a standard mode state at the moment; when the current display brightness of the display screen is higher than 500 nits, the terminal is in an excitation brightness mode at the moment. When it is determined that the current terminal is in the excited brightness mode according to the current display brightness of the display screen, step S12 is performed to keep the backlight brightness of the display screen at the second brightness, and adjust the display brightness of the display screen by adjusting the transparency of the cover layer added to the display screen.
In step S12, the backlight brightness of the display screen is maintained at the second brightness, and the display brightness of the display screen is adjusted by adjusting the transparency of the cover layer added to the display screen.
In the disclosed example, when the current terminal is in the excited brightness mode, the backlight brightness provided by the display screen is forced to be increased to the second brightness and is always kept at the second brightness. In order to improve user-friendly use experience, the display brightness provided by the display screen is more suitable for the current environment brightness, and when the display brightness of the display screen is adjusted, the display brightness can be adjusted by adjusting the transparency of the masking layer added when the excitation mode is started. In one embodiment, in the luminance excitation mode, the higher the transparency of the mask layer, the higher the display luminance of the corresponding display screen. When the transparency of the masking layer is at a maximum, the display brightness is a second brightness. When the transparency of the masking layer is the minimum value, the display brightness is the first brightness. By adjusting the transparency of the covering layer, the display brightness of the display screen can be adjusted between the first brightness and the second brightness, and further the brightness interval displayed by the display screen is widened, so that the influence of display brightness jump brought to user visual experience due to hardware limitation is reduced. In another embodiment, the second brightness may be determined based on the performance of the display screen, and the display brightness of the display screen produced by different manufacturers may be forced to be increased differently.
In one embodiment, the transparency of the mask layer is adjusted based on the correspondence between the ambient brightness and the display brightness. Based on the results of the multiple tests, in the brightness interval between the first brightness and the second brightness of the display screen, the linear relationship between each ambient brightness and each display brightness in the brightness interval under the environment brightness with different brightness and over-bright brightness can be determined, and the linear relationship can be as shown in fig. 3. And then under the mode of exciting luminance, can be according to external ambient brightness, through the transparency of adjusting the covering layer, make the display screen show the display luminance corresponding with external ambient brightness under the effect of covering layer. For example: the first brightness of the terminal is 500 nits, and the environment brightness of the terminal is 10000 nits; the second luminance is 800 nits for an ambient luminance of 20000 nits. Based on the results of the multiple tests, it can be determined that when the external environment brightness is 15000 nits, the display screen has a suitable display brightness of 650 nits. When the light sensor detects that the ambient brightness outside is 15000 nits, the excitation brightness mode is started, the backlight brightness is increased from 500 nits to 800 nits, meanwhile, the masking layer is added, the transparency of the masking layer is improved, the display brightness of the display screen is increased from 500 nits to 650 nits, and therefore the situation that the display brightness of the display is too bright is avoided.
Through the embodiment, when the brightness is adjusted, the current terminal can be determined to be in the excitation brightness mode according to the determined current display brightness of the display screen, and the display brightness of the display screen is adjusted in a mode of adjusting the transparency of the cover layer based on the backlight brightness, so that smooth transition of the display brightness from the first brightness to the second brightness is realized.
Based on the same idea, the present disclosure also provides another brightness adjustment manner.
Fig. 4 is a flowchart illustrating a brightness adjustment method according to an exemplary embodiment, where as shown in fig. 4, the brightness adjustment method 20 is applied to a terminal, the terminal includes a display screen, and the brightness adjustment method 20 includes the following steps S21, S221, and S222.
In step S21, the current display brightness of the display screen is determined.
If the current display brightness is higher than the first brightness, step S221 is executed. In step S221, the backlight brightness of the display screen is maintained at the second brightness, and the display brightness of the display screen is adjusted by adjusting the transparency of the cover layer added to the display screen.
In the present disclosure, the implementation of step S21 and step S221 is the same as the implementation of step S11 and step S12 in the brightness adjusting method 10, and will not be described again.
If the current display brightness is lower than or equal to the first brightness, step S222 is executed. In step S222, the display brightness of the display screen is adjusted by adjusting the backlight brightness of the display screen.
In the embodiment of the disclosure, if the current display brightness is lower than or equal to the first brightness, the current terminal is in the standard brightness mode, and when the display brightness of the screen is adjusted, the backlight brightness of the display screen of the terminal can be determined according to the ambient brightness detected by the light sensor, and the provided backlight brightness is directly used as the display brightness, and the display brightness is adjusted through the backlight brightness without adding a masking layer, so that the automatic brightness adjustment of the display screen is realized.
Through the embodiment, the brightness adjustment can be determined according to the determined current display brightness of the display screen. When the display screen is in the standard mode, the display brightness of the display screen is adjusted by adjusting the backlight brightness provided by the display screen. When the display screen is in the excitation brightness mode, the display brightness of the display screen is adjusted in a mode of adjusting the transparency of the cover layer based on the backlight brightness. Aiming at different display brightness, different brightness adjusting modes are provided for adjustment, so that the adjusting mode is more targeted, the display brightness interval of the display screen is widened, the visual influence of display brightness jumping on a user is reduced, the use experience of the user is improved, and the visual fatigue of the user in use is reduced.
Based on the same idea, the present disclosure also provides another brightness adjustment manner.
Fig. 5 is a flowchart illustrating a brightness adjustment method according to an exemplary embodiment, where as shown in fig. 5, the brightness adjustment method 30 is applied to a terminal, the terminal includes a display screen, and the brightness adjustment method 30 includes the following steps S31 to S33.
In step S31, the current ambient brightness is acquired.
In the embodiment of the present disclosure, the current ambient brightness may be monitored in real time by a light sensor in the terminal. By acquiring the current ambient brightness, the display brightness which is displayed by the display screen aiming at the current ambient brightness can be determined, and therefore a user can conveniently provide proper display brightness when using the display screen.
In step S32, a target display brightness of the display screen corresponding to the current ambient brightness is determined.
In the embodiment of the present disclosure, a mapping relationship between the external environment brightness and the display brightness of the display screen is preset. And then according to the current ambient brightness detected by the light sensor, the target display brightness of the display screen corresponding to the current ambient brightness can be determined based on a preset mapping relation. Therefore, the display mode of starting is selected according to the determined target display brightness, and the targeted brightness adjustment is facilitated.
In step S33, the display brightness of the display screen is adjusted to the target display brightness based on the current display brightness of the display screen.
In the embodiment of the present disclosure, the determined target display brightness is compared with the current display brightness, and is used to determine whether the current display brightness displayed by the display screen is suitable for the current ambient brightness. And then based on the current display brightness, the display brightness of the display screen is adjusted to the required target display brightness, so that the adjusted display brightness is more suitable for the user to use under the current environment brightness.
In an embodiment, when the determined target display brightness is the same as the current display brightness, it may be indicated that the external light intensity is not changed, the current display brightness is the target display brightness required to be displayed, and the display brightness of the display screen may be continuously maintained at the current display brightness.
In another embodiment, when the current display brightness is lower than or equal to the first brightness, the current display mode of the display screen is the standard mode, and the backlight brightness of the display screen is the same as the display brightness. If the determined target display brightness is lower than or equal to the first brightness and is different from the current display brightness, the display brightness of the display screen can be adjusted by adjusting the backlight brightness provided by the display screen in the standard mode, and the current display brightness is adjusted to the target display brightness.
In another embodiment, if the current display brightness is lower than or equal to the first brightness and the target display brightness is higher than the first brightness, the backlight brightness of the display screen is adjusted to the first brightness; keeping the backlight brightness of the display screen at a second brightness, and meanwhile, adding a covering layer on the display screen to enable the current display brightness to be a first brightness; and adjusting the display brightness of the display screen to the target display brightness by improving the transparency of the covering layer. In the case of this embodiment, the standard mode needs to be adjusted to the excitation luminance mode and then adjusted. The activation of the excitation luminance mode forcibly increases the display luminance of the display screen to display the luminance in an abnormal state, and if the excitation luminance mode is activated for a long time, the service life of the display screen is easily shortened or the display screen is easily broken down. In order to protect the service life of the display screen and meet the use requirements of a user, when the cross-brightness mode is adjusted, the current display brightness needs to be adjusted to the first brightness, and then the brightness exciting mode is started. And increasing the backlight brightness from the first brightness to the second brightness, and adjusting the display brightness to the target display brightness by adjusting the transparency of the mask layer. When the brightness mode is excited to start, a covering layer is added in the display screen, so that the brightness jump is avoided when the low backlight brightness is directly connected to the second brightness, the smooth transition of the display brightness of the two modes is ensured, and the irreversible damage of the display screen is avoided. At this time, the transparency of the masking layer is the lowest, and the display brightness of the display screen with the backlight brightness of the second brightness is controlled to be the first brightness. And then the display brightness of the display screen is adjusted to the target display brightness by improving the transparency of the covering layer.
In another embodiment, when the current display brightness is higher than the first brightness, the display mode of the current display screen is the excitation brightness mode, and the backlight brightness is the second brightness, and the adjustment is performed by arranging the cover layer with transparency. If the determined target display brightness is higher than the first brightness, the current display brightness can be adjusted to the target display brightness by adjusting the transparency of the masking layer.
In another embodiment, if the current display brightness is higher than the first brightness and the target display brightness is lower than or equal to the first brightness, then: maintaining the second brightness based on the backlight brightness of the display screen, and adjusting the display brightness of the display screen to the first brightness by reducing the transparency of the mask layer; adjusting the backlight brightness of the display screen to a first brightness, and withdrawing the covering layer from the display screen; and adjusting the display brightness of the display screen to the target display brightness based on the first brightness. In the case of this embodiment, when performing the adjustment, it is necessary to adjust the excitation luminance pattern to the standard pattern and then perform the adjustment. When the brightness is adjusted, the transparency of the mask layer is reduced, the display brightness of the current display is adjusted to the first brightness, the excitation brightness mode is closed, and the mask layer is withdrawn, so that the smooth transition of the display brightness of the two modes is ensured. And then adjusting the current display mode to the standard mode, and adjusting the display brightness of the display screen to the target display brightness by adjusting the backlight brightness provided by the display screen.
In another embodiment, to avoid the temporary jump of the external light, the backlight brightness is increased to the second brightness and then changed back to the original low backlight brightness, which affects the user experience. When carrying out luminance adjustment, can confirm according to the mobile state at terminal, and then carry out reasonable luminance adjustment, make the user when using, the demonstration luminance of display screen is fit for the user and uses under current environment, and can see the content in the display screen clearly to promote user's use and experience. The moving state may include a static state or a moving state, and the determination of the moving state of the terminal may be performed according to any electronic device that determines the position of an object, such as an acceleration sensor, a gyroscope sensor, or an acceleration gyro sensor in the terminal.
Especially, the backlight brightness adopts the second brightness, which causes a certain burden on the display screen, so that when the target display brightness determined according to the ambient brightness jumps to be higher than the first brightness, the moving state of the terminal is firstly confirmed, and whether the display brightness is adjusted in time is determined according to the moving state, or whether the adjustment is carried out is judged through delayed confirmation. In this embodiment, if the current display brightness is lower than or equal to the first brightness and the target display brightness is higher than the first brightness, then: acquiring a moving state of a terminal; if the moving state is a static state, the ambient brightness is acquired again after the specified time; and if the moving state is the motion state, directly adjusting the display brightness.
Generally, when the terminal is in a moving state, the surrounding environment may change, such as going from indoor to outdoor, and so on.
And under the condition that the terminal is static, the terminal is stably positioned in a fixed environment, the ambient light generally does not change violently, and if the ambient light is detected to be suddenly enhanced, the false recognition caused by the short-time light can be realized. Therefore, under the condition that the target display brightness determined according to the ambient brightness jumps to be higher than the first brightness, if the terminal is judged to be in a static state, the ambient light is obtained again after the specified time, and if the target display brightness determined by the obtained ambient light is still higher than the first brightness, the situation is not mistakenly identified, and the adjustment can be carried out. The specified time may be 1 second or other time. Through this kind of mode, can avoid the condition of repeatedly adjusting backlight luminance to second luminance that some misrecognitions caused, protect the display screen, also improve user experience.
In still another embodiment, in any display mode, when the display brightness of the display screen needs to be adjusted, the adjustment can be performed by detecting whether the external environment brightness changes within a specified time, which is further helpful for stable adjustment of the display brightness of the display screen. Therefore, the phenomenon that the user generates visual fatigue when the user uses the LED display screen due to the fact that the light sensor breaks down or the ambient brightness jumps temporarily when monitoring the ambient brightness is avoided, and the adjustment is too sensitive.
Based on the same conception, the embodiment of the disclosure also provides a brightness adjusting device.
It is understood that, in order to implement the above functions, the brightness adjustment apparatus provided in the embodiments of the present disclosure includes a hardware structure and/or a software module for performing each function. The disclosed embodiments can be implemented in hardware or a combination of hardware and computer software, in combination with the exemplary elements and algorithm steps disclosed in the disclosed embodiments. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present disclosure.
