Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, 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.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The display method, the display device, and the electronic device provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
At present, in a low-speed refresh scenario, if the display unit does not have a frame buffer, the host needs to transmit data to the display unit in real time, and the interaction between the two is continuous, which may result in too high power consumption. If the display unit is provided with a frame buffer, the display unit can utilize the frame buffer to buffer the data, and the host does not need to transmit the data frequently and in real time. Therefore, in a low-speed refresh scenario (especially when the picture is still), the power consumption is low with the frame buffer.
In the high-speed refresh scenario, the host needs to transmit data to the display unit more frequently because the picture is updated quickly. In this case, the higher the frequency of using the frame buffer by the display unit, the greater the increase in the frame rate, the less significant the effect of the frame buffer, and instead, the increased power consumption due to the increased frequency of using the frame buffer. Therefore, in a high-speed refreshing scene, if the frame buffer does not work, the display unit displays data in real time, and the power consumption is low.
Based on the above, the embodiment of the application provides a display method, a display device and electronic equipment. The following first explains a display method provided in an embodiment of the present application.
Fig. 1 is a schematic flowchart of a display method according to an embodiment of the present application. The display method may include:
s101: and determining the refresh rate of the display unit at the second moment according to the first target data and/or the refresh rate of the display unit at the first moment.
The first target data is data to be displayed, the display unit comprises a frame buffer, and the second moment is a moment after the first moment.
S102: and under the condition that the refresh rate at the second moment is greater than the preset refresh rate, displaying the first target data in a first display mode.
Wherein, in the first display mode, the frame buffer is in a non-working state.
It should be noted that, in the display method provided in the embodiment of the present application, the execution main body may be a display device, or a control module in the display device for executing the loading display method. In the embodiment of the present application, a display device executing a loading display method is taken as an example to describe the display method provided in the embodiment of the present application.
The display device determines the refresh rate of the display unit at the second moment according to the first target data and/or the refresh rate of the display unit at the first moment; and under the condition that the refresh rate at the second moment is greater than the preset refresh rate, displaying the first target data in a first display mode.
Specific implementations of the above steps will be described in detail below.
In the embodiment of the application, the refresh rate of the display unit at the second moment is determined according to the first target data and/or the refresh rate of the display unit at the first moment; and further, under the condition that the refresh rate of the display unit at the second moment is greater than the preset refresh rate, the first target data can be displayed in a first display mode, wherein the frame buffer included in the display unit is in a non-working state in the first display mode. Therefore, under the condition that the refresh rate of the display unit is greater than the preset refresh rate, the frame buffer is in a non-working state, the data to be displayed is directly transmitted to the display unit for displaying without being cached in the frame buffer, and therefore the phenomenon that the power consumption is too high due to too high use frequency of the frame buffer is avoided. Therefore, when the refresh rate of the display unit is high, power consumption can be reduced, and the power consumption can be reduced more remarkably as the refresh rate is higher.
In a video playing scene, the first target data may be a video frame next to a currently played video frame. In the context of browsing a web page or application program interface, the first target data may be a page or interface of a control link clicked by a user in the currently displayed interface.
In some possible implementations of the embodiments of the present application, in S101, a refresh rate of the display unit at the second time may be predicted according to the first target data. Optionally, the determining, according to the first target data, the refresh rate of the display unit at the second time in S101 may include: and determining the refresh rate of the display unit at the second moment according to the number of controls and/or the number of classes included in the first target data.
The display device can count the number and/or the class number of each page in a plurality of pages in advance, and the refresh rate of the display unit when each page is displayed, so as to establish the corresponding relation between the number and/or the class number of the controls and the refresh rate of the display unit.
The controls of the embodiments of the present application include, but are not limited to: list boxes, combo boxes, text boxes, buttons, charts, and the like. The class in the embodiment of the present application refers to a class included in the code corresponding to the first target data. The class is the basis for realizing information encapsulation by object-oriented programming and is a user-defined reference data type.
The following describes a display method provided in the embodiment of the present application, with the number of controls as an example.
For example, it is assumed that the correspondence between the number of controls and the refresh rate of the display unit is shown in table 1.
TABLE 1
The display device counts the number of controls included in the first target data. It is assumed that an interface corresponding to the first target data is shown in fig. 2, and fig. 2 is a schematic interface diagram corresponding to the first target data provided in the embodiment of the present application. Among them, fig. 2 includes 32 controls, among which 17 textbox controls, 14 pure icon button controls, and 1 pure picture button control. The 17 textbox controls are textbox controls corresponding to "< return", "my order", "view all orders >", "to be paid", "to be shipped", "to be received", "to be evaluated", "commodity collection", "store collection", "browsing history", "refund after sales", "coupon", "member center", "home page", "search", "shopping cart", and "personal center", respectively. The 14 pure icon button controls are pure icon button controls corresponding to a "to-be-paid icon", "to-be-delivered icon", "to-be-received icon", "to-be-evaluated icon", "commodity collection icon", "store collection icon", "browsing history icon", "refund after-sales icon", "coupon icon", "member center icon", "home page icon", "search icon", "shopping cart icon", and "personal center icon", respectively. The 1 picture only button control is a picture only button control corresponding to a "user image".
The display device counts that the first target data comprises 32 controls. Further, the display apparatus determines that the refresh rate of the display unit at the second time is greater than 75FPS according to the above table 1.
The corresponding relation between the number of the controls and the refresh rate of the display unit and the preset refresh rate can be set according to actual needs. The embodiments of the present application are not limited thereto.
Fig. 3 is a schematic diagram of a class list included in first target data provided in an embodiment of the present application. As can be seen from fig. 3, the first target data includes 6 classes, which are: example wallpaper (example wallpapers) class, slide and drag list view Demo (slide and drag list view Demo) class, notepad (Noter) class, phone and message Storage (phonepandmessaging Storage) class, Calendar Storage (Calendar Storage) class, media Storage (MediaStorage) class, and Documents (Documents) class.
The process of determining the refresh rate of the display unit at the second time according to the number of controls and the number of classes included in the first target data and the process of determining the refresh rate of the display unit at the second time according to the number of classes included in the first target data are similar to the process of determining the refresh rate of the display unit at the second time according to the number of controls included in the first target data, and specifically, the process of determining the refresh rate of the display unit at the second time may refer to the number of controls included in the first target data. The embodiments of the present application are not described herein in detail.
In the embodiment of the application, the refresh rate of the display unit at the second moment can be determined according to the number and/or class number of the controls included in the first target data, and then the first target data can be displayed in the first display mode under the condition that the refresh rate of the display unit at the second moment is greater than the preset refresh rate, wherein the frame buffer included in the display unit is in a non-working state under the first display mode. Therefore, under the condition that the refresh rate of the display unit is greater than the preset refresh rate, the frame buffer is in a non-working state, the data to be displayed is directly transmitted to the display unit for displaying without being cached in the frame buffer, and therefore the phenomenon that the power consumption is too high due to too high use frequency of the frame buffer is avoided. In the case where the refresh rate of the display unit is high, power consumption can be reduced, and the higher the refresh rate is, the more significant the reduction in power consumption is.
In some possible implementations of the embodiment of the present application, in S101, the refresh rate of the display unit at the second time may be determined according to the refresh rate of the display unit at the first time.
Illustratively, assume that the refresh rate of the display cell at the first instant is 65 Frames Per Second (FPS). The refresh rate of the display unit at the first moment in time may be taken as the refresh rate of the display unit at the second moment in time, i.e. it is determined that the refresh rate of the display unit at the first moment in time is also 65 FPS.
In some possible implementations of the embodiment of the present application, before S101, the display method provided in the embodiment of the present application may further include: and determining the refresh rate of the display unit at the first moment according to the working state information of the image processor or the input frequency of a user for the display unit in a preset time period.
Wherein the operating state information of the image processor may include at least one of the following items:
busy-idle condition information, load information, and operating frequency information.
In some possible implementations of the embodiment of the present application, the display device may count the operating state information of the image processor in a certain time period and the average refresh rate of the display unit in the time period in advance, and further establish a corresponding relationship between the operating state information of the image processor and the refresh rate of the display unit.
After the display device acquires the current working state information of the image processing, the refresh rate of the display unit at the first moment is determined according to the corresponding relation between the working state information of the image processor and the refresh rate of the display unit.
Illustratively, the busy-idle condition of the image processor is assumed to include: busy and idle. The correspondence relationship between the busy/idle condition information of the image processor and the refresh rate of the display unit, which is established in advance, is shown in table 2.
TABLE 2
In some possible implementations of the embodiments of the present application, the busy-idle condition information of the image processor may be obtained through a flag bit for representing the busy-idle condition information of the image processor. For example, the flag bit is 0 to indicate that the image processor is in an idle state, and the flag bit is 1 to indicate that the image processor is in a very busy state.
Assuming that the flag bit indicating the busy-idle condition information of the image processor acquired by the display device is 1, it is determined that the image processor is in a very busy state. Further, the display apparatus determines that the refresh rate of the display unit at the first time is greater than 75FPS according to the above table 2, and further, the display apparatus may determine that the refresh rate of the display unit at the second time is greater than 75 FPS.
The corresponding relationship between the busy and idle condition information of the image processor and the refresh rate of the display unit and the preset refresh rate can be set according to actual needs. The embodiments of the present application are not limited thereto.
As another example, it is assumed that the correspondence between the load condition of the image processor and the refresh rate of the display unit is as shown in table 3.
TABLE 3
The display device monitors the load condition of the image processor. Suppose that the display device monitors that the load of the image processor is greater than or equal to 80%. Further, the display apparatus determines that the refresh rate of the display unit at the first time is greater than 75FPS according to the above table 3, and further, the display apparatus may determine that the refresh rate of the display unit at the second time is greater than 75 FPS.
The corresponding relation between the load information of the image processor and the refresh rate of the display unit and the preset refresh rate can be set according to actual needs. The embodiments of the present application are not limited thereto.
As another example, it is assumed that the correspondence relationship between the operating frequency of the image processor and the refresh rate of the display unit is as shown in table 4.
TABLE 4
The display device monitors the operating frequency of the image processor. Suppose that the display device monitors the operating frequency of the image processor to be 2.5 GHz. Further, the display apparatus determines that the refresh rate of the display unit at the first time is greater than 75FPS according to the above table 4, and further, the display apparatus may determine that the refresh rate of the display unit at the second time is greater than 75 FPS.
The corresponding relation between the operating frequency of the image processor and the refresh rate of the display unit and the preset refresh rate can be set according to actual needs. The embodiments of the present application are not limited thereto.
In the embodiment of the application, the refresh rate of the display unit at the first moment can be determined according to the working state information of the image processor, and further the refresh rate of the display unit at the second moment can be determined according to the refresh rate of the display unit at the first moment; and further, under the condition that the refresh rate of the display unit at the second moment is greater than the preset refresh rate, the first target data can be displayed in a first display mode, wherein the frame buffer included in the display unit is in a non-working state in the first display mode. Therefore, under the condition that the refresh rate of the display unit is greater than the preset refresh rate, the frame buffer is in a non-working state, the data to be displayed is directly transmitted to the display unit for displaying without being cached in the frame buffer, and therefore the phenomenon that the power consumption is too high due to too high use frequency of the frame buffer is avoided. In the case where the refresh rate of the display unit is high, power consumption can be reduced, and the higher the refresh rate is, the more significant the reduction in power consumption is.
In some possible implementations of the embodiment of the application, the display device may count in advance an input frequency of a user for the display unit in a certain time period and a refresh rate of the display unit in the time period, and further establish a corresponding relationship between the input frequency of the user for the display unit and the refresh rate of the display unit.
For example, it is assumed that the correspondence relationship between the input frequency of the user for the display unit and the refresh rate of the display unit is as shown in table 5.
TABLE 5
The display device monitors the input times of the user aiming at each minute of the display unit, and then obtains the input frequency of the user aiming at the display unit. Suppose that the display device monitors that the input frequency of the user for each minute of the display unit is 30 times, and obtains the input frequency of the user for the display unit of 30 times per minute. Further, the display apparatus determines that the refresh rate of the display unit at the first time is greater than 75FPS according to the above table 5, and further, the display apparatus may determine that the refresh rate of the display unit at the second time is greater than 75 FPS.
The input frequency of the user for the display unit and the corresponding relation of the refresh rate of the display unit and the preset refresh rate can be set according to actual needs. The embodiments of the present application are not limited thereto.
In the embodiment of the application, the refresh rate of the display unit at the first moment can be determined according to the input frequency of a user for the display unit, and then the refresh rate of the display unit at the second moment can be determined according to the refresh rate of the display unit at the first moment; and under the condition that the refresh rate of the display unit at the second moment is greater than the preset refresh rate, displaying the first target data in a first display mode, wherein the frame buffer included in the display unit is in a non-working state in the first display mode. Therefore, under the condition that the refresh rate of the display unit is greater than the preset refresh rate, the frame buffer is in a non-working state, the data to be displayed is directly transmitted to the display unit for displaying without being cached in the frame buffer, and therefore the phenomenon that the power consumption is too high due to too high use frequency of the frame buffer is avoided. In the case where the refresh rate of the display unit is high, power consumption can be reduced, and the higher the refresh rate is, the more significant the reduction in power consumption is.
In some possible implementations of the embodiment of the present application, determining the current refresh rate of the display unit according to the operating state information of the image processor or the input frequency of the user for the display unit within a preset time period may include: and under the condition that the current moment is a preset moment or the display input aiming at the first target data is received, determining the refresh rate of the first moment of the display unit according to the working state information of the image processor or the input frequency of a user aiming at the display unit in a preset time period.
For example, assume preset times of 12:15, 6:30, and 9: 45. And when the current time reaches any one of the preset times, determining the refresh rate of the first time of the display unit according to the working state information of the image processor or the input frequency of the user aiming at the display unit in a preset time period.
For another example, assuming that a previous interface currently displaying the first target data is provided, after the user clicks a control for displaying the first target data in the previous interface, the refresh rate of the display unit at the first moment is determined according to the working state information of the image processor or the input frequency of the user for the display unit within a preset time period.
In the embodiment of the application, the refresh rate of the display unit at the first moment is determined according to the working state information of the image processor or the input frequency of the user for the display unit within the preset time period under the condition that the current moment is the preset moment or the display input aiming at the first target data is received. The refresh rate of the display unit at the first moment is not determined in real time according to the working state information of the image processor or the input frequency of the user aiming at the display unit in the preset time period, so that the situation that the system resource is occupied by determining the refresh rate of the display unit at the first moment in real time is avoided. The occupation of system resources can be reduced.
In some possible implementations of the embodiment of the present application, in S101, a refresh rate of the display unit at the second time may be determined according to the first target data and the refresh rate of the display unit at the first time.
In this embodiment, the process of determining the refresh rate of the display unit at the first moment is not described herein again, and reference may be specifically made to the process of determining the refresh rate of the display unit at the first moment.
If it is determined that the refresh rate of the display unit at the first time is greater than 75FPS, and it is determined that the refresh rate of the display unit at the second time is greater than 70FPS according to the first target data, the two may be combined to determine that the refresh rate of the display unit at the second time is greater than 75 FPS.
For S102, in some possible implementations of the embodiment of the present application, the preset refresh rate in S102 may be 75 FPS. The preset refresh rate may be set according to actual needs, and the embodiment of the present application is not limited herein.
In some possible implementations of the embodiment of the present application, the first display mode in S102 may be a Video mode (Video mode). In the video mode, the frame buffer of the display unit does not work, and the display unit directly displays the data to be displayed after receiving the data to be displayed without caching the data to be displayed in the frame buffer.
In the embodiment of the application, under the condition that the refresh rate of the display unit is greater than the preset refresh rate, the frame buffer is in a non-working state, and the data to be displayed is directly transmitted to the display unit for displaying without being cached in the frame buffer, so that the phenomenon of overhigh power consumption caused by overhigh use frequency of the frame buffer is avoided. Therefore, when the refresh rate of the display unit is high, power consumption can be reduced, and the power consumption can be reduced more remarkably as the refresh rate is higher.
In some possible implementations of the embodiment of the present application, in a case that the refresh rate of the display unit at the second time is greater than the preset refresh rate, before S102, the display method provided in the embodiment of the present application may further include: and sending first indication information to the display unit, wherein the first indication information is used for indicating the display unit to control the frame buffer to be in a non-working state.
For example, it is assumed that the indication information corresponding to the working state of the frame buffer is 1, and the indication information corresponding to the non-working state is 0. And after the display device determines that the refresh rate of the display unit at the second moment is greater than the preset refresh rate, the display device sends 0 to the display unit, and the display unit sets the state of the frame buffer to be in a non-working state according to the 0 sent by the display device. Then, the first target data is displayed in the first display mode.
In some possible implementations of the embodiments of the application, sending the first indication information to the display unit may include: and sending first indication information to a display unit under the condition that the frame buffer is in the working state.
For example, the display device may obtain a current state of the frame buffer, for example, monitor the state of the frame buffer, or send a state request to the display unit after a refresh rate of the display unit at the second time is greater than a preset refresh rate, and the display unit feeds back the state of the frame buffer to the display device after receiving the state request; or, the display device may record the state of the frame buffer after sending the indication information to the display unit each time, and further determine the current state of the frame buffer according to the previously recorded state of the frame buffer.
When the refresh rate is greater than the preset refresh rate but the frame buffer is in the non-working state, since the frame buffer is in the non-working state at this time, it is not necessary to send indication information for indicating the display unit to control the frame buffer to be in the non-working state to the display unit. According to the embodiment of the application, the first indication information is sent to the display unit only when the frame buffer is in the working state, so that system resources occupied by frequently sending the first indication information to the display unit can be avoided.
In some possible implementations of the embodiment of the present application, after S102, the display method provided in the embodiment of the present application may further include: and under the condition that the refresh rate at the third moment is not greater than the preset refresh rate, displaying the second target data in a second display mode, wherein the refresh rate at the third moment is determined according to the second target data and/or the refresh rate at the second moment, the third moment is the moment after the second moment, and under the second display mode, the frame buffer is in a working state.
The process of determining the refresh rate at the third time according to the second target data and/or the refresh rate at the second time is similar to the process of determining the refresh rate at the second time according to the first target data and/or the refresh rate at the first time, and specifically, reference may be made to the above process. The embodiments of the present application are not described herein in detail.
For example, assuming that at the first time, the display device determines that the refresh rate of the display unit at the second time is greater than the preset refresh rate, the first target data is displayed in the first display mode.
And then, when the time reaches the second moment, the display device determines that the refresh rate of the display unit at the third moment is not greater than the preset refresh rate, and second target data are displayed in a second display mode.
In some possible implementations of embodiments of the present application, the second display mode may be a command mode (Commandmode). In the command mode, the frame buffer of the display unit works, after the display unit receives the data to be displayed, the data to be displayed is firstly stored in the frame buffer, and then the data to be displayed is read from the frame buffer for displaying.
In the embodiment of the application, under the condition that the refresh rate of the display unit is not greater than the preset refresh rate, the frame buffer is in a working state, the data to be displayed is firstly cached in the frame buffer, and then the data to be displayed is read from the frame buffer for displaying. Therefore, the phenomenon of overhigh power consumption caused by real-time interaction of the host and the display unit is avoided. Therefore, when the refresh rate of the display unit is low, power consumption can be reduced, and the lower the refresh rate, the more significant the reduction in power consumption.
In the embodiment of the application, under the condition of low frame rate, the work of the frame buffer is lower than the work of the frame buffer in power consumption. In case of high frame rate, the frame buffer non-operation consumes less power than the frame buffer operation. Therefore, when the refresh rate is low, the frame buffer included in the display unit is in an active state, and power consumption can be reduced. Under the condition of low refresh rate, the frame buffer included in the display unit is in a non-working state, so that the power consumption can be reduced.
In some possible implementations of the embodiment of the present application, after S102, before displaying the second target data in the second display mode, the display method provided in the embodiment of the present application may further include: and sending second indication information to the display unit, wherein the second indication information is used for indicating the display unit to control the frame buffer to be in a working state.
For example, it is assumed that the indication information corresponding to the working state of the frame buffer is 1, and the indication information corresponding to the non-working state is 0. And after the display device determines that the refresh rate of the display unit at the third moment is not greater than the preset refresh rate, the display device sends 1 to the display unit, and the display unit sets the state of the frame buffer to be a working state according to the 1 sent by the display device. Then, the second target data is displayed in the second display mode.
In some possible implementations of the embodiment of the present application, sending the second indication information to the display unit may include: and sending second indication information to the display unit under the condition that the frame buffer is in the non-working state.
For example, the display device may obtain a current state of the frame buffer, for example, monitor the state of the frame buffer, or send a state request to the display unit after determining that the refresh rate of the display unit at the third time is not greater than the preset refresh rate, and the display unit feeds back the state of the frame buffer to the display device after receiving the state request; or, the display device may record the state of the frame buffer after sending the indication information to the display unit each time, and further determine the current state of the frame buffer according to the previously recorded state of the frame buffer.
In the embodiment of the present application, when the refresh rate is not greater than the preset refresh rate but the frame buffer is in the working state, since the frame buffer is in the working state at this time, it is not necessary to send indication information for indicating that the display unit controls the frame buffer to be in the working state to the display unit. Therefore, when the frame buffer is in the non-working state, the second indication information is sent to the display unit, and system resources occupied by frequently sending the second indication information to the display unit can be avoided.
