Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
It should be noted that the terms "first \ second \ third" referred to in the embodiments of the present application are only used for distinguishing similar objects and do not represent a specific ordering for the objects, and it should be understood that "first \ second \ third" may be interchanged under specific ordering or sequence if allowed, so that the embodiments of the present application described herein can be implemented in other orders than illustrated or described herein.
Terminals, such as mobile phones and tablet computers, have become tools frequently used in daily life and work of people. To ensure a better user experience, the display refresh rate of the display screen of the terminal is typically set to a fixed maximum refresh rate. When the terminal runs in the state, no matter what application is started by the user, the display can respond quickly and timely, so that the user can obtain good experience when using the terminal.
With the development of terminal display screens, more and more high display refresh rate screen terminals are coming out. The high display refresh rate screen obviously improves experiences such as games, high definition video, and the promotion that for example experienced to First Person's Shooting (FPS) game is very obvious, and the high display refresh rate screen can bring more smooth visual angle and switch, makes the more light accurate locking enemy position of player. Therefore, terminals with high display refresh rate screens are receiving increasing attention and preference from multiple users, particularly loyalty fans of terminal games.
Obviously, the use experience of the user can be better improved by improving the display refresh rate. However, for a touch screen sharing a module with a display screen, especially for some flexible screens which are more trendy at present, a high display refresh rate inevitably brings more noise interference.
In the related technology, for a high frame rate flexible display screen, an additional hardware pin is specially added as a hardware synchronization pin for the display screen and a touch screen. When the display refresh rate is changed, the hardware synchronization pin synchronizes information to the touch screen to dynamically adjust the scanning period of the touch screen so as to achieve the optimal noise reduction effect. However, the hardware synchronization pin adds complexity to the hardware design circuit and increases the hardware cost of the mobile phone.
The embodiment of the application provides a synchronization method for displaying refresh rate, which is applied to a terminal, wherein the terminal can be various types of equipment with a display screen system and a touch screen system in the implementation process, and the display refresh rate is synchronized by interaction between the display screen system and the touch screen system.
Fig. 1 is a schematic flowchart of a method for synchronizing a display refresh rate according to an embodiment of the present application, where as shown in fig. 1, the method at least includes the following steps:
step S110, the display screen system determines a display refresh rate of the display screen.
Here, the display screen system at least comprises a display screen, a sensor and a control module, wherein the display screen can be a flexible display screen with a bending function or other conventional display screens; the sensor is used for generating a display signal; the control module at least comprises a microcontroller for controlling the display screen to display corresponding contents according to the display signal, and in some embodiments, the control module may further comprise a display driver.
Here, the display refresh rate is the frequency of screen refresh during the display process of the display screen, and represents how many times the picture is refreshed every second. Conventional Display devices such as Cathode Ray Tubes (CRTs), liquid Crystal Displays (LCDs), light Emitting Diodes (LEDs), organic Light Emitting Diodes (OLEDs), active Matrix OLEDs (AMOLEDs) operate at a fixed Display refresh rate such as 60Hz, 85Hz or 120 Hz.
Step S120, the display screen system informs the touch screen system of the display refresh rate.
Here, the touch screen system includes at least a touch screen panel including a plurality of driving electrodes and a plurality of sensing electrodes for detecting a touch point position, a touch sensor, and a control module; the touch sensor is used for generating a touch signal according to touch operation; the control module at least comprises a microcontroller and is used for controlling the touch screen to generate response according to the touch signal; in some embodiments, the control module further includes a touch driver, a touch Integrated Circuit (IC).
Here, the display screen system sends a notification message to the touch screen system, and synchronizes the determined rate of the display refresh ICs to the touch screen system, so that the touch screen system acquires the current display refresh rate. For example, the display screen system may be implemented by way of a notification chain message to notify the touch screen system of the display refresh rate.
It should be noted that each subsystem in the Linux kernel of the operating system is interdependent, and when a state of one subsystem changes, a certain mechanism must be used to notify other subsystems using its service, so that the other subsystems can take corresponding measures. To meet such a demand, the kernel implements an event notification chain mechanism (notification chain). The kernel-provided notification chain mechanism is mainly used for communication between different subsystems and is based on events and priorities. For example, the touch screen belongs to an input subsystem, and the corresponding events can be triggered when the screen is on and off by acquiring a frame buffer (frame buffer) subsystem.
And step S130, the touch screen system adjusts the detection parameters of the touch screen according to the display refresh rate.
Here, the detection parameters of the touch screen are represented by the state of the touch IC, such as hardware scanning frequency, touch hit rate, and lock point range. The touch reporting rate is the frequency of reporting contact information to the host computer every second, such as 180Hz, and the faster reporting rate enables the terminal screen to detect the finger of the user more quickly; the lock point range is understood to be the range of the area around the actual position of the user's finger when touched.
It should be noted that the touch screen may be various types of touch screens. For example, the touch screen is a surround screen, a full screen, a water drop full screen, a curved screen, or a bang screen.
Here, the touch screen system adjusts the detection parameter of the touch screen to a value matching the display refresh rate according to the obtained display refresh rate, for example, when the display refresh rate is 60Hz, the pixels of the display screen are refreshed every 16.6 milliseconds (ms), and at this time, to avoid noise interference, the touch IC should be dynamically switched to the optimal low-noise scanning frequency point according to the display refresh rate.
In the embodiment of the application, firstly, a display screen system determines the display refresh rate of a display screen; then, the display screen system notifies the touch screen system of the display refresh rate; finally, the touch screen system adjusts the detection parameters of the touch screen according to the display refresh rate; therefore, the display screen system can realize the problem of synchronization of the display refresh rate and the touch screen by determining the display refresh rate of the display screen and informing the touch screen system of the display refresh rate, and the circuit complexity and the extra cost loss caused by using a hardware synchronization pin are optimized.
Fig. 2 is a schematic flowchart of another method for synchronizing a display refresh rate according to an embodiment of the present application, where as shown in fig. 2, the method at least includes the following steps:
step S210, the display screen system determines the current display refresh rate of the display screen.
Here, the display refresh rate is a current display refresh rate of the display screen, and is generally set to a fixed value such as 90Hz.
And step S220, the display screen system determines a target display refresh rate according to the display requirements of the picture to be displayed.
Here, the display requirement of the to-be-displayed picture may be a logic designed for the terminal software itself, for example, an adaptive display refresh rate is adjusted according to the system memory occupancy rate, or a display refresh rate autonomously selected by the user as needed.
It should be noted that, after the target display refresh rate of the display screen is determined, the control module further controls the display screen to read and display the display frame data to be displayed from the frame buffer unit of the display screen at the frequency of the target refresh rate.
When the mobile terminal is used, the application programs can be classified into 3 types according to the display requirements of the display screen: the first category is FPS games, which have the highest requirement on the display refresh rate, and need to run at the highest display refresh rate to ensure smooth pictures and timely response; the second type is a video type, which has a second highest requirement on the display refresh rate; the third type is a general type of application, the requirement on the display refresh rate is not high, and the picture application requirement can be ensured by running at a lower display refresh rate. That is, in the implementation process, the corresponding target display refresh rate can be set according to different display requirements. Compared with the step that the display screen is refreshed at a fixed maximum refresh rate, the step can reduce the power consumption of the display screen of the mobile terminal.
Step S230, in a case that the target display refresh rate is not consistent with the current display refresh rate, the display screen system determines that the display refresh rate of the display screen changes.
Here, by comparing the target display refresh rate and the current display refresh rate, if the target display refresh rate and the current display refresh rate are not consistent, it may be determined that switching of the display refresh rate is performed, that is, the display refresh rate of the display screen is changed.
Step S240, in a case that it is determined that the display refresh rate of the display screen changes, the display screen system notifies the touch screen system of the display refresh rate.
Here, if it is determined that the display refresh rate of the display screen is changed, the display screen system notifies the touch screen system of the changed display refresh rate, i.e., the target display refresh rate, so as to achieve synchronization of the display screen system and the touch screen system.
And step S250, the touch screen system adjusts the detection parameters of the touch screen according to the display refresh rate.
Here, the touch screen system dynamically adjusts the detection parameter of the touch screen to a value matching the display refresh rate according to the obtained changed display refresh rate.
In the embodiment of the application, firstly, a display screen system determines a target display refresh rate according to the display requirements of a picture to be displayed; secondly, the display screen system determines that the display refresh rate of the display screen changes by comparing the current display refresh rate with the target display refresh rate; then, the display screen system informs the touch screen system of the display refresh rate under the condition that the display refresh rate of the display screen is determined to be changed; therefore, when the display refresh rate is changed, the display screen system synchronizes information to the touch screen system, the problem of synchronization of the display refresh rate and the touch screen is solved, and the circuit complexity and the extra cost loss caused by using a hardware synchronization angle are avoided.
Fig. 3 is an interaction flowchart of another method for synchronizing a display refresh rate according to an embodiment of the present application, where as shown in fig. 3, a display screen system includes a display driver, and a touch screen system includes a touch driver and a touch IC, and the method at least includes the following steps:
step S310, the display driver switches the display refresh rate of the display screen.
Here, when the user selects switching of the display refresh rate, or the terminal design itself logic decides that the display refresh rate needs to be switched, the display driver starts switching of the display refresh rate.
In step S320, the display driver sends a refresh rate change notification message to the touch driver.
Here, when the display driver switches the display refresh rate, the touch driver is notified in a notification chain message that the display refresh rate has dynamically changed.
Step S330, the touch driving program determines the display refresh rate according to the refresh rate change notification message.
Here, the touch driver registers a callback function on a display notification chain event, and when a refresh rate change notification event occurs, display refresh rate change information is synchronously obtained.
Step S340, the touch driver determines an identifier corresponding to the display refresh rate.
Here, the indication is a numerical value corresponding to a display refresh rate, and different display refresh rates correspond to different indications. In practice, different manufacturers specify respective values, for example, a value of 1 is set to indicate a refresh rate of 90Hz.
In step S350, the touch driver writes the identifier into a specific address register.
Here, the specific address register is used to store identification information and/or detection parameters of the touch screen.
Here, the touch driver writes a value corresponding to the display refresh rate at this time in a specific address register of the touch IC through a Serial Peripheral Interface (SPI) Interface or an Inter-Integrated Circuit (I2C) bus.
Step S360, the touch IC reads the identifier from the specific address register to obtain the display refresh rate.
Here, when the touch IC detects a change in the value in the specific address register, the display refresh rate is determined by reading the flag corresponding to the display refresh rate.
And step S370, the touch IC adjusts the detection parameters of the touch screen to be values matched with the display refresh rate according to the display refresh rate.
Here, the detection parameter of the touch screen includes at least one of: the scanning frequency of the touch screen, the report rate of the touch screen and the lock point range of the touch screen.
It is worth noting that by synchronously displaying the refresh rate information, the scanning frequency of the touch screen can be adjusted, touch detection parameters such as a report rate and a locking range can be dynamically optimized to achieve an extremely good touch effect, and a user can have better use experience in scenes such as games.
In the embodiment of the application, when the display driver switches the display refresh rate, the touch driver is notified in a manner of a notification chain message that the display refresh rate is dynamically changed, and after receiving the message, the touch driver dynamically changes the state of the touch screen IC, such as the scanning frequency, in a manner of reading and writing the register by I2C; therefore, the problem of display refresh rate and touch screen synchronization is achieved by using a software mode, circuit complexity and extra cost loss caused by using a hardware synchronization pin are optimized, synchronization is more flexible, and touch experience is improved while noise interference is solved.
The foregoing method for synchronizing display refresh rates is described below with reference to a specific embodiment, but it should be noted that the specific embodiment is only for better describing the present application and is not intended to limit the present application.
The embodiment of the application provides a software synchronization mode to achieve the effect basically consistent with a hardware synchronization pin. The basic idea of software synchronization is to notify the TP of the change in the display refresh rate at that time in a software manner when the user dynamically switches the display refresh rate. Fig. 4 is a logic flow diagram of a method for synchronizing a display refresh rate according to an embodiment of the present application, and as shown in fig. 4, a specific implementation process at least includes the following steps:
step S401, according to the upper layer logic, the display refresh rate switching is determined.
Here, the upper layer logic may autonomously select switching of the display refresh rate for the user, or logic of the terminal itself is designed.
In some possible embodiments, whether a touch screen of the mobile terminal has a user touch operation or not can be detected, and if so, the refresh rate of the display screen of the mobile terminal is adjusted to be the highest refresh rate; and if not, maintaining the refresh rate of the display screen of the mobile terminal unchanged. After the step is set, when the user touches the mobile terminal to realize interaction, the display screen is adjusted to run at the highest refresh rate.
In step S402, the display driver switches the display refresh rate.
Here, when the user selects to switch the display refresh rate, or the terminal design logic itself determines that the display refresh rate needs to be switched, the underlying display driver is notified to start switching the display refresh rate.
In step S403, the display driver sends a display refresh rate change notification message to the touch driver.
Here, the display refresh rate change notification message may be one notification chain message. In implementation, the touch driver registers a callback function on a notification chain event. When the display driver completes the refresh rate switching, the touch driver is notified of the dynamic change of the display refresh rate in a notification chain message manner.
In step S404, the touch driver acquires display refresh rate information.
In step S405, the touch driver notifies the touch IC refresh rate information through the SPI interface or the I2C bus.
Here, after receiving the message, the touch driver notifies the touch IC of the latest refresh rate information through the SPI interface or the I2C read/write register.
In step S406, the touch IC changes the state of the touch IC according to the refresh rate information.
Here, the touch IC dynamically changes the state of the touch IC according to the acquired refresh rate information, such as changing a hardware scan frequency, dynamically switching a touch point rate, adjusting a lock point range, and the like.
Fig. 5 is a flowchart illustrating displaying a notification chain according to an embodiment of the present application. As shown in fig. 5, originally, for the touch driver, only the screen-on event 51 and the screen-off event 52 are display notification chain events that need to be used, and the embodiment of the present application adds a new notification event, i.e., a refresh rate change event 53, to the original display notification chain 50 to notify the refresh rate change.
Here, the display notification chain 50 is a list of event handling functions that may be used to send state change information to code segments that request such changes. Each notification chain is related to a certain event or events, and when a specific event occurs, a callback function in the corresponding event notification chain is called to perform corresponding processing.
It should be noted that the display notification chain mechanism uses a publish-subscribe model: when an event occurs, a subsystem of the kernel component which detects or generates the event serves as an active party, and a subscriber (a subsystem interested in the event) serving as a passive party is informed through a notification function. Of course, if a subscribing party needs to handle event notifications issued on a certain event notification chain, it should register callback functions on that notification chain at initialization.
Notably, the subscriber must know which event notification support is provided by the other subsystems to select event notifications that can be subscribed to; of course, the subscriber itself is also a subsystem and therefore also has information publishing functionality, and it is also clear which events within the system are valuable to other subsystems, i.e. which events within the system need to be notified to the subscriber when they occur, but the subsystem has no knowledge of who subscribes to event notifications and why they subscribe.
The design has the advantage of the specification of the whole software flow, and better obeys the permission of the kernel modules to realize the notification chain instead of simple function call-back. Although the traditional function callback mode is simple to implement, the coupling degree between modules can be increased, and the continuation and the development of codes are not facilitated.
The embodiment of the present application addresses software synchronization between the display refresh rate and the touch screen by adding a refresh rate change event 53 to the display notification chain 50, and then the touch driver receives the event and performs a corresponding process 54. Generally, the touch driver writes corresponding values into the fixed address register of the touch IC by means of I2C bus, which represents different display refresh rates. When the touch IC detects the change of the register value, the touch IC can be immediately dynamically switched to the optimal low-noise scanning frequency point according to the display refresh rate at the moment.
In some embodiments, according to the requirements of different items, it is further required to make the touch IC perform more customized processing when the display refresh rate changes, such as dynamically switching the report rate, the lock point range, and the like, and the touch IC may write the corresponding operation register to dynamically modify the dynamically switching report rate or the lock point range while receiving the notification event of the change of the refresh rate, so as to achieve the best touch experience.
In the embodiment of the application, the display refresh rate and the touch screen are synchronized by using software. Not only optimized the circuit complexity and the extra cost loss that use hardware synchronization foot to bring, still let this kind of synchronization more nimble, promoted touch experience when solving noise interference. For the user, the user can experience better display effect and extremely-close touch experience at different display refresh rates, the use experience of the user in scenes such as game playing is obviously improved, and the selling points of the mobile phone and the public praise of the user are increased.
Based on the traditional synchronization scheme for refreshing the display hardware, the software synchronization mode is adopted for the first time to achieve the noise reduction effect consistent with the hardware synchronization pin. Meanwhile, the software implementation mode follows the communication standard design mode of a kernel module, and a notification chain mode is adopted to enable the code to have larger expandability and continuity. Finally, the scanning frequency of the touch IC can be adjusted under different display refresh rates, different touch parameters can be dynamically optimized to achieve an extremely good touch effect, and users can have better use experience in scenes such as games.
