Detailed Description
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Please refer to fig. 1, which is an application environment diagram of a screen backlight setting method according to an embodiment of the present application. As shown in fig. 1, the method may be applied to an electronic device having a display screen and requiring local highlighting of the display screen, such as a mobile electronic device capable of performing data processing on the mobile, such as a mobile phone, a tablet computer, a laptop computer, a smart watch, smart glasses, and a smart camera, or a non-mobile electronic device capable of performing data processing on the mobile, such as a liquid crystal television, a kiosk, and a desktop computer. Fig. 1 is an example of a smart phone, but the practical application may not be limited thereto.
Typically, a scene requiring local highlighting of a display screen is, for example, an off-screen fingerprint unlocking scene as shown in fig. 1, in which a user fingerprint is acquired through the screen for fingerprint recognition and unlocking. It will be appreciated that in practical applications, the scene in which the display screen is locally highlighted may not be limited to this.
Taking fingerprint identification as an example, when a finger of a user touches the surface of the display screen, or the user presses a fingerprint unlocking shortcut key, the user is triggered to enter a highlight mode, and the highlight and light supplement are performed on the display screen through a screen backlight setting method provided in each embodiment described below, so that a fingerprint image can be obtained and the fingerprint unlocking is performed. When the fingerprint unlocking operation is finished, the exit from the high-brightness mode is triggered, and the brightness of the screen and the mask are subjected to parameter configuration again through a screen backlight setting method provided in each embodiment described below so as to adapt to the requirements of a new operating environment.
Please refer to fig. 2, which is a schematic diagram illustrating an implementation flow of a method for setting a screen backlight according to an embodiment of the present application. The method can be applied to electronic devices which are provided with display screens and need to carry out local highlighting processing on the display screens, such as mobile electronic devices which can carry out data processing in moving, such as mobile phones, tablet computers, portable computers, intelligent watches, intelligent glasses, intelligent cameras and the like, or non-mobile electronic devices which can not carry out data processing in moving, such as liquid crystal televisions, all-in-one machines, desktop computers and the like. As shown in fig. 2, the method mainly includes:
201. carrying out parameter configuration on the backlight brightness of the screen;
according to different operation scene changes of the terminal, the backlight brightness of the screen and the configuration parameters of the mask need to be correspondingly adjusted. For example, when the entering into the highlight mode or the exiting from the highlight mode is triggered, the backlight brightness of the screen needs to be re-configured. Under the scene of unlocking fingerprints under the screen, when the fingerprint unlocking device is triggered to enter a highlight mode, the backlight brightness needs to be adjusted to realize highlight and light supplement, and therefore the optical fingerprints are identified. The high brightness refers to high brightness, and entering the high brightness mode makes the brightness of the backlight brighter than that in the normal mode. In the high-brightness mode, the value of the backlight brightness parameter is typically in the range of 460 to 600nit (nit). In contrast, in the non-highlight mode, the backlight brightness typically has a parameter value ranging from 5 to 430 nit.
Due to the influence of hardware performance, a certain time is required for the backlight brightness to take effect (that is, to achieve a highlight display effect) from the parameter configuration to the newly configured parameter, and the newly configured parameter can take effect after the parameter configuration of the mask, so that the parameter configuration of the backlight brightness and the mask is preferably performed at first in order to complete the parameter configuration of the backlight brightness and the mask at the fastest speed.
202. After a first preset number of frame synchronization signals arrive, carrying out parameter configuration on a mask of a screen;
the frame synchronization signal, such as a frame synchronization signal between the lcd controller and the lcd driver, indicates the start of scanning a frame, i.e., a picture displayed by the lcd. The LCD controller generates a frame synchronizing signal immediately after the display of a frame of picture is finished, and starts to display a new frame of picture.
The mask may be, for example, an alpha mask, such as a Dim layer mask. A Dim layer mask is inserted between the fingerprint layer and the common layer, so that the layer below the mask can be pressed by alpha of the mask to be darkened in brightness, but the layer above the mask or outside the covering range of the mask is not affected. Therefore, the brightness of different layers can be adjusted through the mask, and the function of local brightness adjustment is achieved.
Specifically, after the backlight brightness of the screen is configured, the new configured backlight brightness parameter will not be valid immediately, and meanwhile, the mask will not be configured, but the arrival of the frame synchronization signal is waited. When a first preset number of continuous frame synchronization signals arrive, parameter configuration is carried out on the mask.
The parameters of the backlight brightness and the alpha mask are generally effective in the frame, and the configured parameters can be determined to be effective in the next few frames through the corresponding identification information of the frame during the parameter configuration and the preset parameter effective time. Therefore, the first preset number of the waiting frame synchronization signals can be determined according to the corresponding frame when the configured new parameter of the backlight brightness is effective and the preset delay time. The first preset number is an integer greater than or equal to 1. The preset delay time is set based on the hardware driving requirements and in order to achieve better synchronization of the backlight brightness and the configuration of the mask.
203. And synchronizing the backlight brightness and the parameters of the mask which are configured in effect after a second preset number of frame synchronization signals arrive.
Specifically, after the mask is subjected to parameter configuration, the configured mask parameters do not take effect immediately, but continue to wait for the arrival of the frame synchronization signals, and when a second preset number of frame synchronization signals arrive, the newly configured backlight brightness and the parameters of the mask take effect synchronously. The second preset number is an integer greater than or equal to 1, and may be determined according to hardware requirements for implementing backlight brightness and mask configuration. It can be understood that, in practical applications, the first preset number and the second preset number may also be customized by a user according to actual requirements.
In this embodiment, after the parameter configuration is performed on the backlight brightness of the screen, the parameter configuration is performed on the mask of the screen after the first preset number of frame synchronization signals arrive, and then the backlight brightness and the parameters of the mask which are configured in effect are synchronized after the second preset number of frame synchronization signals arrive, so that the synchronization timing sequence of the backlight brightness and the mask is strictly ensured, the situation that the backlight brightness and the synchronization timing sequence of the mask are disturbed due to the frame synchronization signals generated between the backlight brightness and the configuration process of the mask can be avoided, the high synchronization of the backlight brightness and the mask configuration is realized, and the situation that the screen flashes or flashes when entering or exiting from the highlight mode is effectively avoided.
Please refer to fig. 3, which is a schematic flow chart illustrating an implementation of a method for setting a screen backlight according to another embodiment of the present application. The method can be applied to electronic devices which are provided with display screens and need to carry out local highlighting processing on the display screens, such as mobile electronic devices which can carry out data processing in moving, such as mobile phones, tablet computers, portable computers, intelligent watches, intelligent glasses, intelligent cameras and the like, or non-mobile electronic devices which can not carry out data processing in moving, such as liquid crystal televisions, all-in-one machines, desktop computers and the like. As shown in fig. 3, the method mainly includes:
301. when the screen is triggered to enter a highlight mode, carrying out parameter configuration on the backlight brightness of the screen;
specifically, when a finger of a user touches the surface of the display screen, or the user presses a fingerprint unlocking shortcut key, the highlight mode is triggered to enter, the backlight brightness of the screen is configured as a parameter, and the parameter of the backlight brightness is configured as a first preset parameter, so that the backlight brightness of the screen is improved to the highest or preset brightness, and the highlight display effect is achieved. Entering the highlight mode refers to switching from the normal brightness display mode to the highlight display mode.
Optionally, in consideration of the situation that the screen is more shiny or shiny when the frame synchronization signal is generated between the backlight brightness and the configuration process of the mask, before the parameter configuration of the backlight brightness of the screen, it may be determined whether the frame synchronization signal is to be generated between the backlight brightness and the parameter configuration of the mask, and the configuration mode is determined according to the result of the determination, so as to improve the flexibility and efficiency of the configuration. Specifically, when the mode is triggered to enter the highlight mode, whether a frame synchronization signal is generated between the backlight brightness and the parameter configuration of the mask is judged. If a frame synchronization signal is generated between the backlight brightness and the parameter configuration of the mask, which indicates that a screen may flash or turn black, step 301 is performed to perform the parameter configuration and the subsequent steps on the backlight brightness of the screen. If the frame synchronization signal is not generated between the backlight brightness and the parameter configuration of the mask, which indicates that the screen is not flashing or blacking, the parameter configuration is performed on the backlight brightness and the mask at the same time, and the frame synchronization signal does not need to be waited for, so as to improve the configuration and effective speed. And further, after parameter configuration is carried out on the backlight brightness and the mask at the same time, the configuration parameters of the backlight brightness and the mask are synchronously taken into effect after a frame synchronization signal arrives.
Optionally, the determining whether a frame synchronization signal is to be generated between the backlight brightness and the parameter configuration of the mask may specifically include: and judging whether the frame synchronization signal is generated between the backlight brightness and the parameter configuration of the mask or not according to the arrival time of the frame synchronization signal which arrives at the last time at present, the predicted arrival time of the frame synchronization signal which arrives at the next time, the parameter configuration time of the backlight brightness and the preset delay time. The preset delay time may include, but is not limited to: the time required to enable the mask configuration after the backlight brightness setting and the preset offset time, which can generally be determined according to hardware performance. The time required to enable the mask configuration after the backlight brightness setting, or the time required to validate the backlight brightness setting on the hardware.
It is understood that the parameter configuration time of the backlight brightness and the preset delay time are added to obtain the expected configuration time of the mask, and if the expected arrival time of the next arriving frame synchronization signal is between the parameter configuration time of the backlight brightness and the expected configuration time of the mask, it is determined that the frame synchronization signal will be generated between the parameter configuration time of the backlight brightness and the parameter configuration of the mask. If the expected arrival time of the next frame sync signal is after the expected configuration time of the mask, it is determined that the frame sync signal will not be generated between the backlight brightness and the parameter configuration of the mask.
302. After the two frame synchronization signals arrive, carrying out parameter configuration on a mask of a screen;
303. after a frame synchronization signal arrives, synchronizing the backlight brightness and the parameters of the mask which are configured in effect;
the frame synchronization signal, such as a frame synchronization signal between the lcd controller and the lcd driver, indicates the start of scanning a frame, i.e., a picture displayed by the lcd. The LCD controller generates a frame synchronizing signal immediately after the display of a frame of picture is finished, and starts to display a new frame of picture.
The mask may be, for example, an alpha mask, such as a Dim layer mask. A Dim layer mask is inserted between the fingerprint layer and the common layer, so that the layer below the mask can be pressed by alpha of the mask to be darkened in brightness, but the layer above the mask or outside the covering range of the mask is not affected. Therefore, the brightness of different layers can be adjusted through the mask, and the function of local brightness adjustment is achieved.
Specifically, with reference to fig. 4, after the parameter configuration is performed on the backlight brightness of the screen, the newly configured parameter of the backlight brightness does not take effect immediately, and meanwhile, the parameter configuration is not performed on the mask, but after the two frame synchronization signals arrive, the parameter configuration is performed on the mask. Then, after the mask is subjected to parameter configuration, the configured mask parameters and backlight brightness parameters do not take effect immediately, but continue to wait for the arrival of the frame synchronization signal, and when a frame synchronization signal arrives, the backlight brightness and the mask parameters which are configured in effect are synchronized, that is, the highlight display effect and the mask take effect simultaneously.
Optionally, after the parameter configuration is performed on the backlight brightness, the parameter configuration is performed on the mask at the starting time point (frame header) of frame synchronization after the second frame synchronization signal arrives. And synchronizing the backlight brightness of the effective configuration and the parameters of the mask at the starting time point of the frame synchronization after the first frame synchronization signal arrives after the parameter configuration is carried out on the mask.
304. And when the exit of the highlight mode is triggered, simultaneously configuring parameters of the backlight brightness and the mask.
Exiting the highlight mode refers to a transition from the highlight mode to the normal brightness display mode. Specifically, the condition for triggering the exit from the highlight mode may be, for example, an event for triggering the end of the unlocking operation is monitored, specifically, a fingerprint unlocking success notification event, or a fingerprint unlocking recognition failure notification event, or an event for triggering the end of the unlocking operation that a button or a key or a menu is clicked, and the like; or else, for example, an event that a button or key or menu for triggering exit from the highlighted mode is clicked is monitored, and so on.
And when the exit of the highlight mode is triggered, simultaneously configuring the backlight brightness and the parameters of the mask as the second preset parameters corresponding to the backlight brightness and the parameters of the mask. Further, the parameters of the configured backlight brightness and the parameters of the mask are immediately validated. Optionally, as shown in fig. 5, after the mask is configured with the parameters, the configured parameters of the mask and the parameters of the backlight brightness do not take effect immediately, but continue to wait for the arrival of the frame synchronization signal, and when a frame synchronization signal arrives, the parameters of the backlight brightness and the mask configured in effect are synchronized, for example: the backlight brightness is restored to the normal brightness while the mask is hidden.
In this embodiment, after the parameter configuration is performed on the backlight brightness of the screen, the parameter configuration is performed on the mask of the screen after the first preset number of frame synchronization signals arrive, and then the parameter configuration is performed on the backlight brightness and the configuration parameters of the mask after the second preset number of frame synchronization signals arrive, so that the synchronization timing sequence of the backlight brightness and the mask is strictly ensured, the situation that the backlight brightness and the synchronization timing sequence of the mask are disturbed due to the frame synchronization signals generated between the backlight brightness and the configuration process of the mask is avoided, the high synchronization of the backlight brightness and the mask configuration is realized, and the situation that the screen flashes or flashes when entering or exiting from the highlight mode is effectively avoided.
