Description

TECHNICAL FIELD

[0002] Generally, the display screen refresh process of a terminal such as a mobile phone or a computer includes an application page synthesis operation and a display operation. A drawing surface component outputs a synthesized application page to a display screen for display through the application page synthesis operation. With the development of terminal technology, a terminal supports a high refresh rate and adopts different refresh rates according to different application scenarios. For example, a refresh rate of 30 frames per second is adopted in a reading scenario to save power consumption, and a refresh rate of 90 frames per second is adopted in a game scenario to achieve smoother performance and balance performance and power consumption. Currently, when adjusting the refresh rate of a display screen, a timing calibration synchronization signal is often used to make the frame rate of a drawing surface component consistent with the refresh rate of a display screen.

[0060] Figure 1 is a flowchart of a display screen refresh rate adjustment method according to an example embodiment, as shown in Figure 1 the method comprises:

[0061] Step S110, when detecting an adjustment instruction for adjusting the refresh rate of the display screen, determining whether a drawing surface component detects an adjustment notification generated based on the adjustment instruction;

[0062] Step S120, if the drawing surface component detects the adjustment notification, controlling the drawing surface component to generate a notification response corresponding to the adjustment notification;

[0063] Step S130: If the notification response is detected on the display screen, the refresh rate of the display screen is adjusted according to the notification response.

[0064] In this embodiment, the terminal includes an application program, a synchronization signal management component, a drawing surface component, and a display screen.

[0065] In step S110, after detecting the adjustment command, and before adjusting the display refresh rate, the display generates an adjustment notification and sends it to the drawing surface component. This notification informs the drawing surface component that it will adjust the refresh rate. Generally, multiple operating scenarios exist during terminal operation, and different scenarios may require different display refresh rates. For example, when switching from a currently running game application to a reading application, the display refresh rate needs to be reduced to lower power consumption. Conversely, when switching from a currently running reading application to a game application, the display refresh rate needs to be increased to ensure smooth display.

[0066] The refresh rate is the frame rate at which the terminal's display refreshes the application pages; that is, the number of application pages displayed per second. The unit is usually Hz.

[0067] Taking a terminal with an Android system as an example, the process of displaying an application page on the terminal, from generation to display, roughly includes:

[0068] Step S111, draw the application page (also known as an image); for example: Figure 2 As shown, to display a complete application page, it is generally necessary to draw two parts: the status bar content and the application's own design content. After the application has finished drawing the application page, it sends a composition request to the drawing surface component (also known as Surfaceflinger).

[0069] Step S112: Composite application page; After receiving the composite request, the drawing surface component begins to composite multiple parts of the content into an application page to be displayed.

[0070] Step S113: Display the application page; The display screen (also known as Display) is used to display the application page to be displayed.

[0071] After each frame of application page is brushed, the display screen needs to send a synchronization signal (also referred to as Vsync) to the drawing surface component through the synchronization signal management component (also referred to as HWComposer) to inform the drawing surface component to synthesize the next frame of application page, so as to ensure the synchronization between the drawing surface component and the display screen, realize the drawing surface component synthesizing a frame of application page, and the display screen displaying a frame of application page. In an ideal state, the refresh rate of the display screen is equal to the frame rate of the drawing surface component.

[0072] The frame rate refers to the synthesis frame rate, that is, the number of application pages synthesized by the drawing surface component per second. For example, 60 frames per second means that at most 60 pictures are synthesized per second, and each picture is about 16 ms.

[0073] Therefore, whether the display screen is smooth is related to not only the refresh rate of the display screen but also the frame rate of the drawing surface component, and there is a time difference between the adjustment of the refresh rate and the adjustment of the frame rate. In the embodiment of the present disclosure, after the adjustment instruction of the refresh rate of the display screen is detected, the display screen sends an adjustment notification to the drawing surface component, the drawing surface component can timely adjust the frame rate, and the problem of the refresh rate jitter of the display screen caused by the lag of the frame rate adjustment of the drawing surface component can be effectively improved.

[0074] In step S120, after the drawing surface component receives the adjustment notification, a notification response is generated based on the adjustment notification, and the notification response is returned to the display screen. The notification response is used to indicate that the drawing surface component is in a state in which the frame rate can be adjusted, that is, through the notification response, the display screen can know that the current drawing surface component has met the condition of adjusting the frame rate and is in a state in which the frame rate can be adjusted. Through the adjustment notification and the notification response, the handshake between the drawing surface component and the display screen is realized, a suitable opportunity for adjusting the refresh rate is provided, and the smoothness of the display is beneficially ensured.

[0075] In actual application, the drawing surface component generates a notification response corresponding to the adjustment notification, and sends the notification response to the display screen, and also triggers the adjustment of the frequency of generating the synchronization signal. For example, the drawing surface component generates a notification response corresponding to the adjustment notification, and sends the notification response to the display screen, and also sends a calibration instruction for calibrating the frequency of generating the synchronization signal to the synchronization signal management component. The frequency of generating the synchronization signal is the number of synchronization signals generated per second.

[0076] In step S130, after the drawing surface component returns the notification response to the display screen, the drawing surface component initiates an action of adjusting the frame rate of the drawing surface component, so that the adjusted refresh operation of the drawing surface component can be synchronized with the adjusted refresh operation of the display screen more quickly.

[0077] The refresh operation of the display screen refers to an operation of displaying an application page by the display screen, and one refresh operation of the display screen means that the display screen displays one frame of the application page. The refresh operation of the drawing surface component refers to an operation of synthesizing the application page by the drawing surface component, and one refresh operation of the drawing surface component means that the drawing surface component synthesizes one frame of the application page.

[0078] Generally, the drawing surface component performs one refresh operation after the display screen performs one refresh operation, that is, the refresh operation of the drawing surface component is synchronized with the refresh operation of the display screen. By adjusting the refresh rate of the display screen to be equal to the frame rate of the drawing surface component, the refresh operation of the drawing surface component can be synchronized with the refresh operation of the display screen.

[0079] If the drawing surface component returns the notification response based on the adjustment notification to the display screen, it indicates that the drawing surface component can perform the adjustment of the frame rate matched with the refresh rate. At this time, the adjustment of the frame rate of the drawing surface component is performed, and the adjustment of the refresh rate of the display screen is also performed, so as to ensure that the adjusted refresh rate of the display screen is equal to the adjusted frame rate of the drawing surface component.

[0080] In the embodiments of the present disclosure, by notifying the drawing surface component before adjusting the refresh rate, the handshake coordination of the refresh operation of the display screen and the refresh operation of the drawing surface component is realized, so that the drawing surface component can be adjusted in time according to the adjustment of the refresh rate of the display screen. The display problem caused by the asynchronization of the refresh operation of the display screen and the refresh operation of the drawing surface component due to the failure of the drawing surface component to adjust the frame rate in time after detecting the adjustment instruction is reduced. The hysteresis problem of the frame rate adjustment of the drawing surface component and the refresh rate jitter problem of the display screen caused by the hysteresis of the frame rate adjustment of the drawing surface component are improved. The smoothness of the refresh operation of the drawing surface component before and after the frame rate adjustment and the smoothness of the refresh operation of the display screen before and after the refresh rate adjustment are improved.

[0081] Before adjusting the refresh rate of the display screen, if the drawing surface component is not notified, in addition to the frame rate lag problem of the drawing surface component, the display will not be smooth due to the adjustment of the forcedness. For example, if the refresh rate of the display screen is adjusted, but at this time the drawing surface component is still performing application page synthesis operation, it will cause the application page displayed on the display screen to transition poorly, play not smoothly, and appear to be stuck. Therefore, the technical solution of the embodiment of the present disclosure coordinates the handshake of the display screen refresh operation and the drawing surface component refresh operation, and also reduces the adjustment forcedness of the display screen refresh rate.

[0082] In other optional embodiments, if the drawing surface component detects the adjustment notification, the drawing surface component is controlled to generate a notification response corresponding to the adjustment notification, including:

[0083] If the drawing surface component detects the adjustment notification, the refresh state of the drawing surface component is determined;

[0084] According to the refresh state of the drawing surface component, the drawing surface component is controlled to generate a notification response corresponding to the adjustment notification.

[0085] The refresh state includes two states of being in a refresh operation and not being in a refresh operation. Among them, being in a refresh operation includes being in a first type of refresh operation that can be completed faster, and being in a second type of refresh operation that is slower to complete. Generally, the first type of refresh operation is a refresh operation for a relatively static application page, which can be completed faster. The second type of refresh operation is a refresh operation for a relatively dynamic application page, which is slower to complete than the first type of refresh operation. For example, the refresh operation for a static application page can be determined as the first type of refresh operation, and the refresh operation for a dynamic application page can be determined as the second type of refresh operation; or the refresh operation whose refresh time required for one refresh operation of the application page is less than a preset time length is determined as the first type of refresh operation, and the refresh operation whose refresh time required for one refresh operation of the application page is greater than or equal to the preset time length is determined as the second type of refresh operation, wherein the size of the preset time length is not limited, and the size of the preset time length can be set according to specific needs.

[0086] In other optional embodiments, according to the refresh state of the drawing surface component, the drawing surface component is controlled to generate a notification response corresponding to the adjustment notification, including:

[0087] if the drawing surface component is in the refreshing operation, after the refreshing operation is completed, the drawing surface component is controlled to generate a notification response corresponding to the adjustment notification; and / or,

[0088] if the drawing surface component is not in the refreshing operation, the drawing surface component is controlled to generate a notification response corresponding to the adjustment notification.

[0089] In actual application, the drawing surface component generates the notification response only after the current refreshing operation of the drawing surface component is completed, i.e. the current refreshing operation of the drawing surface component is not interrupted, thereby effectively ensuring the smoothness of the picture switching of the display screen. That is, after the drawing surface component receives the adjustment notification, the drawing surface component determines whether the current refreshing operation is in progress. If the current refreshing operation is in progress, the drawing surface component generates the notification response corresponding to the adjustment notification after the current refreshing operation is completed. If the current refreshing operation is not in progress, the drawing surface component directly generates the notification response corresponding to the adjustment notification.

[0090] In other optional embodiments, the controlling of the drawing surface component to generate the notification response corresponding to the adjustment notification according to the refreshing state of the drawing surface component comprises:

[0091] if the drawing surface component is in the refreshing operation, determining the page type of the application page currently synthesized by the drawing surface component;

[0092] if the page type is the first type, the drawing surface component is controlled to generate the notification response;

[0093] if the page type is the second type, after a preset time, the drawing surface component is controlled to generate the notification response corresponding to the adjustment notification; wherein the second type is different from the first type.

[0094] In some embodiments, if the drawing surface component is not in the refreshing operation, the drawing surface component is controlled to generate the notification response corresponding to the adjustment notification.

[0095] In some embodiments, if the drawing surface component is not in the refreshing operation, the drawing surface component is controlled to generate the notification response corresponding to the adjustment notification.

[0096] In some embodiments, the first type of application page is an application page corresponding to a first type of application program, and the second type of application page is an application page corresponding to a second type of application program, where the second type of application program is different from the first type of application program. The first type of application program can be a reading type application program or a non-video chat application program. The second type of application program can be a game type, a video playing type, or a live broadcast type application program. In some embodiments, the second type of application program can be determined as a video playing type application program, and the first type of application program can be determined as a non-video playing type application program.

[0097] The second type of application page needs to generate the notification response again after the preset time, after the drawing surface component completes the synthesis of the second type of application page, or is about to complete the second type of application page. The preset time can be 0.5s, 1.0s, or 2s, etc.

[0098] In some embodiments, the first type of application page is a page with a refresh rate lower than a preset rate, and the second type of application page is a page with a refresh rate higher than the preset rate. The preset rate can be 60Hz, 90Hz, or 120Hz. The time for switching one frame of application page does not exceed 16ms, so that when the adjustment notification is received, the synthesized application page will be quickly displayed, and the drawing surface component can timely adjust the frame rate.

[0099] In the embodiments of the present disclosure, the drawing surface component determines the frame rate of the drawing surface component according to the type of the currently synthesized page, further improves the forced adjustment of the refresh rate on the drawing surface component, further reduces the occurrence of page lag during the display of the terminal, and makes the display transition smoother when the refresh rate is switched.

[0100] In other optional embodiments, the method comprises:

[0101] obtaining the configuration frame rate of the application program with display requirements, and determining whether the configuration frame rate is consistent with the refresh rate of the display screen;

[0102] In response to the configuration frame rate being inconsistent with the refresh rate of the display screen, the display screen generates the adjustment instruction; and in response to the configuration frame rate being consistent with the refresh rate of the display screen, the display screen continues to detect whether the configuration frame rate of the application program is consistent with the refresh rate of the display screen.

[0103] In actual applications, the application program with display requirements generally refers to the application program in the foreground. The configuration frame rate can be understood as the number of application pages drawn by the application per unit of time. The frame rate of the drawing surface component, the configuration frame rate, and the refresh rate need to be consistent.

[0104] The configuration frame rate is a frame rate configured according to the content playback fluency requirement of the application. It can be a default frame rate or a user-defined frame rate. Generally, the higher the content playback fluency of the application, the larger the configuration frame rate.

[0105] Different applications can have different configuration frame rates. Generally, when the configuration frame rate is consistent with the refresh rate of the display screen, the configuration frame rate is equal to the refresh rate of the display screen. When the configuration frame rate is greater than the refresh rate of the display screen or the configuration frame rate is less than the refresh rate of the display screen, it indicates that the configuration frame rate is inconsistent with the refresh rate of the display screen.

[0106] It can be understood that if the configuration frame rate is consistent with the refresh rate of the display screen, there is no need to adjust the refresh rate of the display screen, and there is no need to send an adjustment notification to the drawing surface component.

[0107] In other embodiments, the terminal automatically monitors its own refresh rate and checks the display resource and / or display effect. When it is considered that the refresh rate of the terminal can be adjusted to improve the display effect, the refresh rate of the display screen can be automatically adjusted within a certain range without a configuration frame rate.

[0108] In other optional embodiments, the method comprises:

[0109] According to the notification response, the refresh rate of the display screen is adjusted to be equal to the configuration frame rate.

[0110] According to the notification response, the refresh rate of the display screen is adjusted to be equal to the configuration frame rate.

[0111] The adjusted refresh rate of the display screen is equal to the configuration frame rate, and the frame rate of the drawing surface component is equal to the configuration frame rate.

[0112] It can be understood that adjusting the refresh rate of the display screen to be equal to the configuration frame rate ensures that the display effect of the display screen can adapt to different application requirements.

[0113] In other optional embodiments, the method comprises:

[0114] If the notification response generated by the drawing surface component is detected, a calibration instruction is sent to the synchronization signal management component according to the notification response. The calibration instruction is used to calibrate the generation frequency of the synchronization signal. The synchronization signal is used to synchronize the refresh operation of the drawing surface component and the refresh operation of the display screen.

[0115] In actual application, the drawing surface component returns a notification response to the display screen, indicating that the frame rate of the drawing surface component can be adjusted. Therefore, the drawing surface component sends a calibration instruction to the synchronization signal management component while sending the notification response to the display screen, and the synchronization signal management component adjusts the generation frequency of the synchronization signal through a calibration algorithm module (also referred to as vsync-sf, vsync-app). The generation frequency of the synchronization signal, the frame rate of the drawing surface component, and the refresh rate of the display screen are consistent with each other.

[0116] In this embodiment, the refresh rate is adjusted according to the configured frame rate, so that the adjusted refresh rate is consistent with the configured frame rate; and the generation frequency of the synchronization signal is adjusted according to the refresh rate, so that the generation frequency of the synchronization signal is consistent with the refresh rate. Finally, the configured frame rate, the refresh rate, and the generation frequency of the synchronization signal are consistent with each other. The synchronization between the application page synthesized by the drawing surface component and the application page displayed by the display screen is maintained while meeting the requirements of the application program.

[0117] As shown in FIG. 1, Figure 3 the method for adjusting the refresh rate of the display screen applied to the drawing surface component comprises the following steps.

[0118] In step S210, a notification of adjustment sent by the display screen before adjusting the refresh rate is received.

[0119] In step S220, it is determined that the frame rate of the drawing surface component can be adjusted based on the notification of adjustment.

[0120] In step S230, a notification response indicating confirmation of adjustment is returned to the display screen in response to the fact that the frame rate of the drawing surface component can be adjusted, and the notification response is used to trigger the display screen to adjust the refresh rate.

[0121] In step S210, the notification of adjustment has the functions of reminding and notifying the drawing surface component, so as to timely adjust the frame rate of the drawing surface component.

[0122] In step S220, the notification of adjustment is used to trigger detection of the current working state of the drawing surface component, and then it can be determined whether the frame rate of the drawing surface component can be adjusted.

[0123] In step S230, the technical solution of this embodiment can perform handshake coordination between the display refresh operation and the drawing surface component refresh operation before adjusting the display refresh rate. This reduces display problems caused by the drawing surface component's inability to adjust the frame rate in time when the refresh rate is adjusted immediately after detecting the adjustment command, resulting in asynchrony between the display refresh operation and the drawing surface component refresh operation. This reduces the mandatory nature of the display refresh rate adjustment process, improves the lag problem of the drawing surface component's frame rate adjustment, and alleviates the display refresh rate jitter problem caused by the lag in the drawing surface component's frame rate adjustment. It also improves the smoothness of the drawing surface component refresh operation before and after frame rate adjustment, as well as the fluidity of the display refresh operation before and after refresh rate adjustment.

[0124] In a specific example, such as Figure 4 As shown, the methods for adjusting the screen refresh rate generally include:

[0125] Step S301: The terminal detects an application switching operation;

[0126] Step S302: The terminal obtains the configuration frame rate of the application;

[0127] Step S303: The terminal determines whether the configured frame rate is less than the refresh rate of the display screen. If yes, proceed to step S305; otherwise, proceed to step S304.

[0128] Step S304: The terminal determines whether the configured frame rate is greater than the refresh rate of the display screen.
