The embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, fig. 1 is a flowchart of a control method of a terminal according to an embodiment of the present disclosure, where the terminal according to the embodiment of the present disclosure includes a processor, a display buffer and a display screen, where the display buffer is used to store image frames to be displayed, and the method provided in this embodiment includes the following steps:
s100: in response to a first preset operation, a backlight increasing instruction is generated.
In this embodiment, the first preset operation may be a pressing operation, for example, the display area of the display screen may include a first display area and a second display area, and the first preset operation may be, for example, pressing a biological composition with a biological texture to the second display area of the terminal. Alternatively, the first preset operation may be that the user presses a finger to the second display area of the terminal. In this embodiment, the terminal may be any device of a mobile phone, a tablet, a computer, and an intelligent wearable device, and the type of the terminal is not limited in any way. In some embodiments of the present disclosure, the backlight adding instruction is generated to a backlight control device of the display screen, the backlight control device may be a part of the terminal, for example, may be a backlight controller on the terminal, and the backlight control device may also be a separate device independent from the terminal. In the present embodiment, the backlight increasing instruction is used to increase the backlight brightness of the terminal display area. For example, the backlight increasing instruction may be used to increase the backlight brightness of the terminal display area to a preset maximum backlight brightness.
S200: and when a first screen refreshing signal after the backlight increasing instruction is generated is detected, drawing a preset masking layer into a display cache.
In this embodiment, after the backlight increasing instruction is generated to the backlight control component of the terminal, the screen refresh signal is waited, so that the backlight increasing instruction really takes effect to complete the backlight increasing. The display of the terminal has a certain screen refresh period, i.e. screen refresh time, for example, assuming that the frequency of the display is 60Hz, indicating that the display is refreshed 60 times per second, the time interval for displaying each frame, i.e. the screen refresh time, is 1/60s, which is approximately equal to 16 ms. In some embodiments of the present disclosure, the screen refresh signal is a screen vertical refresh signal (VSync). In some embodiments of the present disclosure, the preset masking layer is used to cover the first display region of the terminal and expose the second display region. In this embodiment, after the backlight increasing instruction is generated, waiting for a first screen refresh signal to appear to enable the backlight increasing instruction to actually take effect, and immediately drawing the preset mask layer into the display buffer when the backlight increasing instruction is generated and the first screen refresh signal is detected, where the display buffer is used to store the display image of the next frame of the terminal, so that drawing the preset mask layer into the display buffer can display the preset mask layer on the first display area of the terminal during screen refresh, that is, the preset mask layer drawn into the display buffer can be displayed on the first display area of the terminal as a part of the image of the next frame. In some embodiments of the present disclosure, the brightness of the first display region when the first display region of the terminal is displayed with the preset mask layer at the time of screen refresh is the same as the brightness of the first display region before responding to the first preset operation, that is, by displaying the preset mask layer on the first display region, the brightness of the first display region after the backlight brightness is increased is the same as the brightness of the first display region before the backlight brightness is increased.
In the prior art, the device for adjusting the screen backlight and the device for drawing the image frame to be displayed operate independently of each other, the screen backlight increasing is asynchronous with the display mask layer, and the synchronous display of the mask layer on the screen cannot be guaranteed after the screen backlight increasing, so when the preset mask layer needs to be displayed in the first display area, the preset mask layer to be displayed cannot be displayed in time after the backlight increasing due to the fact that the screen backlight increasing is asynchronous with the display preset mask layer, and the first display area temporarily shows the too-dark flicker, or the first display area already displays the preset mask layer but the screen backlight is not increased and the first display area temporarily shows the too-dark flicker, in the embodiment of the disclosure, the first screen refresh signal appearing after the backlight increasing instruction is generated is waited for the backlight increasing instruction to take effect, and then the preset mask layer is immediately drawn and displayed in the buffer, therefore, the preset masking layer is displayed in the first display area, the screen backlight increasing and the preset masking layer displaying can be synchronized by adopting the technical scheme, so that the time interval between the backlight increasing and the masking layer displaying is smaller than the screen refreshing time, a user cannot perceive the time interval, the user sees that the display screen does not have excessively bright or excessively dark flicker, and the use experience of the user is improved.
Some embodiments of the present disclosure further provide another terminal control method, and fig. 2 is a flowchart of the another terminal control method according to the embodiments of the present disclosure, and as shown in fig. 2, the terminal control method according to the embodiments of the present disclosure includes:
s100: in response to a first preset operation, a backlight increasing instruction is generated.
S200: and when a first screen refreshing signal after the backlight increasing instruction is generated is detected, drawing a preset masking layer into a display cache.
Steps S100 and S200 in this embodiment are the same as those with the same reference numerals in fig. 1, and the description of the steps in fig. 1 is also applicable to this embodiment, and will not be described again here.
S300: and generating a backlight reduction instruction in response to the second preset operation.
In some embodiments of the disclosure, when the first display area of the display screen displays the cover layer, the terminal sends a backlight reduction instruction to the backlight control assembly after responding to the second preset operation, and the backlight reduction instruction is used for reducing the backlight brightness of the display screen of the terminal.
S400: and when a first screen refreshing signal after the backlight reduction instruction is generated is detected, stopping drawing the preset masking layer into the display cache.
In this embodiment, after the backlight reduction instruction is generated, the first screen refresh signal is waited for the backlight reduction instruction to take effect, so that the backlight is reduced, the backlight of the display screen is not reduced immediately when the backlight reduction instruction is generated, but is reduced when the display screen is refreshed, after the first screen refresh signal is waited for, the preset masking layer is immediately stopped being drawn into the display buffer, and the terminal acquires the image frame to be displayed from the buffer when the screen is displayed, so that the preset masking layer is not drawn into the display buffer any more, and the masking layer can be removed in the first display area when the screen is refreshed. In some optional embodiments of the present disclosure, in response to the brightness of the first display region before the second preset operation, the brightness of the first display region is the same as the brightness of the first display region after the backlight brightness is reduced and the preset mask layer is removed, that is, after the backlight brightness is reduced, the brightness of the first display region before and after the backlight brightness is reduced is kept unchanged by removing the preset mask layer. In this embodiment, after the backlight reduction instruction is generated, a first screen refresh signal is waited to enable the screen backlight with reduced brightness to take effect, and then the drawing of the preset masking layer in the cache is immediately stopped, so that the preset masking layer is removed from the first display area in the next screen refresh.
In some embodiments of the present disclosure, after responding to the first preset operation, before generating the backlight increasing instruction, further comprising: pausing the drawing of the image frame into the display buffer. In this embodiment, after responding to the first preset operation, the drawing of the image into the display buffer is stopped before the backlight increasing instruction takes effect, and the drawing of the image frame into the display buffer is continued after the backlight increasing instruction takes effect, so that the image frame drawn before is stored in the display buffer, and therefore the image displayed on the display screen does not change, that is, the image displayed on the display screen remains unchanged before the screen refresh signal is received. When the image is suspended from the display cache, the screen backlight instruction is enabled to take effect, and then the preset mask layer is rendered and displayed in the display cache.
In some embodiments of the present disclosure, after responding to the second preset operation, before generating the backlight reduction instruction, further comprising: pausing the drawing of the image frame into the display buffer. In this embodiment, after the backlight reduction instruction is generated and the screen refresh time is waited, the image is continuously drawn into the display buffer, but the image drawn into the display buffer does not include the preset cover layer.
In some embodiments of the present disclosure, the backlight brightness before the backlight increasing instruction is in effect is equal to the backlight brightness after the backlight decreasing instruction is in effect. In the present embodiment, the screen backlight luminance before the backlight luminance is increased and after the backlight luminance is decreased is equal, and thus, the user does not perceive the luminance change of the screen backlight.
In some embodiments of the present disclosure, the display area of the display screen comprises the first display area and a second display area; the first preset operation is: pressing to the second display area; and/or the second preset operation is: removing the press on the second display area. Taking the terminal as an intelligent terminal with an off-screen fingerprint identification function as an example, the first preset operation may be that the user presses the second display area with a finger, and the second preset operation may be that the user removes the finger pressed on the second display area.
In order to better explain the technical solution of the present embodiment, steps S100 and S200 in the terminal control method proposed by the embodiment of the present disclosure are explained below with reference to fig. 3. In this embodiment, taking the terminal as an intelligent terminal with an off-screen fingerprint identification function as an example, the intelligent terminal may be an android mobile phone, as shown in fig. 3, a display screen of the intelligent terminal includes a first display area and a second display area, where the second display area may be an area where a fingerprint symbol in fig. 3 is located, the first display area is an area on the display screen except the second display area, the display screen may be provided with a camera below the second display area for collecting a fingerprint of a user, in this embodiment, taking a first preset operation as pressing the second display area with a finger as an example, detecting that the user presses the second display area with the finger, the terminal determines that the user wishes to unlock the screen fingerprint in response to the first preset operation, in order to collect the fingerprint of the user, backlight brightness needs to be increased to shoot a fingerprint image of the user, and at the same time, in order to prevent the user from feeling dazzling, the method includes the steps that a preset masking layer needs to be displayed in a first display area which is not covered by fingers of a user, therefore, a backlight increasing instruction is sent to a backlight control assembly, the backlight increasing instruction does not take effect immediately, a first screen refreshing signal appears after the backlight increasing instruction is generated to enable the backlight increasing instruction to take effect, then the preset masking layer is drawn into a cache, and therefore the preset masking layer is drawn into the first display area when a display screen is refreshed next time. The following description continues with reference to fig. 3 to describe steps S300 and S400 in the control method of the terminal proposed by the embodiment of the present disclosure. After the user performs the identification of the fingerprint under the screen, the finger pressed on the second display area is removed, for example, the second preset operation is the removal of the finger pressed on the second display area, the terminal responds to the second preset operation, because the user can see the second display area after removing the finger, and the backlight of the second display area is strong, the backlight brightness needs to be reduced, and the direct reduction of the backlight can cause the first display area with the preset masking layer to be too dark, a backlight reduction instruction is generated to reduce the backlight after detecting that the user removes the finger, but the backlight reduction instruction cannot be immediately effective, after the backlight reduction instruction is generated, the first screen refresh signal is waited to enable the backlight reduction instruction to be really effective, then the drawing of the preset masking layer to the cache is stopped, and thus the preset masking layer is not displayed in the first display area any more during the next screen refresh. In the embodiment of the disclosure, by adopting the above technical scheme, the screen backlight adjustment and the preset mask layer control can be synchronized, so that the time interval between the backlight increase or decrease and the display or removal of the preset mask layer is less than one screen refresh time, and thus, a user cannot perceive the time interval, and the brightness of the first display area does not change when the user sees.
To better illustrate the beneficial effects of the embodiments of the present disclosure, taking a terminal as an example of an android system, and referring to fig. 3 and fig. 4, an example of an internal control flow of the android system terminal is illustrated, where a fingerprint icon on a display screen of the terminal on fig. 3 is a second display area, an area on the display screen other than the second display area is a first display area, the terminal is a terminal with a fingerprint identification function, a camera is disposed below the second display area, when a user uses a finger to unlock the screen, the finger is pressed on the second display area, a ui (user interface) object detects the pressed finger and responds to the operation, a preset mask layer drawing request is sent to a surfafiner object in the android system, the surfafiner object sends an interrupt to a Kernel (Kernel) of the terminal, the request is to increase backlight brightness, the Kernel drives to generate a backlight increase instruction to the screen, the Kernel waits for a screen vertical refresh signal, and sending an interrupt return to the SurfaceFlinger object, drawing the preset covering layer into a display cache after the SurfaceFlinger object receives the interrupt return, and displaying the preset covering layer into a first display area of the screen when the screen is refreshed next time. When the user removes the finger from the second display area, the fingerprint UI object responds to the operation and sends a preset cover layer removing request to the SurfaceFlinger object, the SurfaceFlinger object sends an interrupt to Kernel to request to reduce the backlight, the Kernel component generates a backlight reducing instruction to be driven by the backlight and sends an interrupt return to the SurfaceFlinger object after waiting for a screen vertical refreshing signal, and the SurfaceFlinger object does not draw the preset cover layer into the display cache after receiving the interrupt return, so that the preset cover layer is removed from the first display area when the next screen is refreshed. In the embodiment of the disclosure, synchronization of backlight adjustment and preset masking layer control is realized, so that the time interval between backlight adjustment and preset masking layer adjustment is less than the vertical refreshing time of one screen, a user is prevented from noticing that the display screen flashes too bright or too dark, and the use experience of the user is improved.
As shown in fig. 5, an embodiment of the present disclosure further provides a control apparatus of a terminal, including a response module 10 and a control module 20;
the response module is used for responding to the first preset operation and generating a backlight increasing instruction;
and the control module is used for drawing a preset masking layer into a display cache when detecting a first screen refreshing signal after the backlight increasing instruction is generated.
