Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. The following terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature.

In the present embodiments, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

In the embodiment of the present application, "and/or" is merely an association relationship describing an association object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

In the description of the present application, it should be noted that, unless explicitly stated and limited otherwise, the terms "disposed," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; the specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

In order to better explain the technical solutions of the present application, the following brief summary of terms related to the present application is provided.

(1) Refresh rate, which is the number of times a screen is refreshed per second of image (picture). The higher the refresh rate, the better the image stability displayed by the screen. For example, when watching a movie, a person sees what is actually a still picture, just like a slide show. The human senses that the picture is moving because the eyes of the human have a visual retention effect, the impression that the previous picture is left in the brain is not lost, the next picture is kept, and the difference between the two pictures is small, and one action is displayed by a plurality of pictures, so that the human senses that the picture is moving, the picture is replaced by the next picture, that is, refreshing, and if one action is completed by 20 pictures, the action looks like a cartoon, and if the number of the actions is increased to 30, the action looks more naturally, that is, the refreshing rate.

(2) Resolution, which refers to how many pixels a display can display. The resolution determines the degree of detail of the bitmap image, and in general, the higher the resolution of the image, the more pixels that are included and the sharper the image.

In order to solve the technical problems in the background art, a display scheme is provided in the embodiment of the application. Firstly, only one display interface is arranged in the electronic equipment, so that the number of the display interfaces in the electronic equipment is saved, and the cost of the electronic equipment is reduced.

It can be understood that if each of the plurality of display interfaces supports a display of one display screen, the displays of the respective display screens may be synchronous or asynchronous, and independent of each other, without affecting each other. If only one display interface exists in the electronic equipment, one display interface can be connected with one display screen of a plurality of display screens, only one display screen can be supported for display, and other display screens can not be supported for display.

In a scene where a user wants to display a plurality of display screens, one display interface cannot support the display of the plurality of display screens, so that the user experience is affected. In order to further solve the technical problem, a switch connected with the display interface can be further arranged in the electronic equipment, the switch can be switched to a plurality of data channels, and the data channels are respectively in one-to-one correspondence with the display screens. In this way, the electronic device can alternately open the plurality of data transmission channels in a mode of alternately opening the switch in a multi-screen display mode, then transmit corresponding display data to the corresponding display screen through the opened data transmission channels, and display contents corresponding to the display data on the plurality of display screens. Wherein the display data may be image data, video data, etc.

In some embodiments, the mobile phone 100 may acquire the display data acquired by the camera in real time, or may acquire the stored display data from the memory.

For example, the electronic device in the embodiments of the present application may be a device including a touch screen, such as a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), an augmented reality (augmented reality, AR) \virtual reality (VR) device, and the specific form of the electronic device is not limited in particular.

The method provided by the embodiment of the application can be applied to electronic equipment with a plurality of display screens. With the development of the product shape of electronic devices, more and more electronic devices support a folded form, and the electronic devices supporting the folded form generally have a plurality of display screens, so that the electronic devices with the plurality of display screens can be electronic devices supporting the folded form. It can be understood that at least two screens formed after the electronic device in the embodiment of the present application is folded may be multiple screens that exist independently, or may be a complete screen of an integral structure, which is only folded to form at least two portions.

For example, the folding screen may be a flexible folding screen. The flexible folding screen comprises folding edges made of flexible materials. Part or all of the flexible folding screen is made of flexible materials. The flexible screen has the characteristic of being bendable, and at least two screens formed by folding the flexible folding screen are a complete screen of an integral structure and are only folded to form at least two parts. And the electronic device has other display screens in addition to the flexible folding screen. It is to be appreciated that an electronic device having a foldable flexible screen may be referred to herein simply as a flexible folding screen electronic device.

For another example, the folding screen of the electronic device may be a multi-screen folding screen. The multi-screen folding screen may include multiple (two or more) screens. The plurality of screens is a plurality of individual display screens. The plurality of screens may be connected in turn by a folding shaft. Each screen can rotate around a folding shaft connected with the screen, so that the folding of the multi-screen folding screen is realized. It will be appreciated that an electronic device that does not have a foldable flexible screen, but has multiple display screens, and that these display screens may be folded according to a folding axis, may be referred to herein simply as a multi-screen folding screen electronic device.

The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the electronic equipment.

In the following, an electronic device is taken as a flexible folding screen electronic device, and the flexible folding screen electronic device is provided with a non-foldable display screen and a flexible folding screen, so that a product form structure suitable for the application is described in detail.

The flexible folding screen is foldable such that it is divided into a plurality of display areas. For example, one foldable screen in the electronic device may be folded along a fold edge or fold axis to form a first screen and a second screen, the first screen and the second screen being display areas.

In some device product forms, the included angle α between the first and second screens of an electronic device with a folding screen has a value in the range of [0 °,180 ° ]. Under the complete folding state of the folding screen, the first screen is opposite to the second screen, the included angle alpha between the first screen and the second screen is 0 degrees, under the complete unfolding state of the folding screen, the first screen and the second screen are on the same plane, and the included angle alpha between the first screen and the second screen is 180 degrees.

In the embodiment of the application, if alpha is 0 degrees and P, the electronic equipment can be determined to be in a folded state; if alpha epsilon (P, 180 DEG), the electronic device can be determined to be in an unfolded state, or if alpha epsilon [0 DEG, P), the electronic device can be determined to be in a folded state; if α ε [ P,180 ], it can be determined that the electronic device is in an expanded state. Wherein P is a preset angle threshold. P may be determined based on usage habits of a large number of users using the folding screen; alternatively, P may be set by the user in the electronic device.

In some embodiments, the user may want to use the first screen and the second screen as a whole (i.e., as a complete display screen) when the angle α between the first screen and the second screen is greater than 90 ° according to the usage habits of most users. Therefore, the preset angle threshold P in the embodiment of the present application may be greater than 90 °. The range of the preset angle threshold P may be (90 °,180 °). For example, the preset angle threshold P may be 100 °, 120 °, 135 °, 140 °, 145 °, 150 °, or the like.

The electronic device has a longer side and a shorter side in a fully unfolded state, and the electronic device product form may be divided into two types, a device product form in which a folding side or a folding axis is parallel to the longer side, and a device product form in which a folding side or a folding axis is parallel to the shorter side.

For example, please refer to fig. 1, which is a schematic diagram of a product form of a mobile phone 100 according to an embodiment of the present application. The mobile phone 100 is in a form of a device product with a front camera disposed on a longer side, and the mobile phone 100 shown in fig. 1 may be referred to as a left-right folded electronic device under a current viewing angle.

Fig. 1 (a) is a schematic view of a state in which the flexible folding screen 103 of the mobile phone 100 is in a fully folded state, and the first screen and the second screen formed by folding the flexible folding screen 103 along folding edges or folding axes are not visible to a user. The cell phone 100 may further include a display 102, the display 102 being disposed on the back of the first or second screen. It will be appreciated that the display 102 is visible to the user whether the handset 100 is in a folded or unfolded state. The flexible folding screen 103 of the handset 100 can be unfolded along the folding edge 101 to form a first screen and a second screen as shown in fig. 1 (b). The flexible folding screen 103 of the mobile phone 100 continues to be unfolded along the folding edge 101, so that the fully unfolded state shown in fig. 1 (c) can be formed, and the first screen and the second screen after being fully unfolded are in the same plane. It will be appreciated that the first and second screens may be used as a whole (i.e., as a complete display) when the handset 100 is in the fully extended state.

For another example, please refer to fig. 2, which is a schematic product form of a mobile phone 100 according to an embodiment of the present application, where the mobile phone 100 is a device product form with a front camera disposed at a shorter side, and the mobile phone 100 shown in fig. 2 may be referred to as an electronic device that is folded up and down under a current viewing angle.

Fig. 2 (a) is a schematic view of the flexible folding screen 103 of the mobile phone 100 in a fully folded state, where the first and second screens formed by folding the flexible folding screen 103 along a folding edge or folding axis are not visible to the user. The cell phone 100 may further include a display 102, the display 102 being disposed on the back of the first or second screen. It will be appreciated that the display 102 is visible to the user whether the handset 100 is in a folded or unfolded state. The flexible folding screen 103 of the handset 100 can be unfolded along the folding edge 101 to form a first screen and a second screen as shown in fig. 2 (b). The flexible folding screen 103 of the mobile phone 100 continues to be unfolded along the folding edge 101, so that the fully unfolded state shown in the (c) diagram in fig. 2 can be formed, and the first screen and the second screen after being fully unfolded are in the same plane. It will be appreciated that the first and second screens may be used as a whole (i.e., as a complete display) when the handset 100 is in the fully extended state.

In the embodiment of the application, the electronic device is taken as a mobile phone, and the mobile phone is provided with two display screens for illustration.

It should be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the mobile phone 100. In other embodiments of the present application, the handset 100 may include more or fewer components than shown, or certain components may be combined, or certain components may be split, or different arrangements of components may be provided. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

The mobile phone 100 implements display functions through a GPU, a display 194, an application processor, and the like. The GPU is a microprocessor for image processing, and is connected to the display 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

The display screen 194 is used to display images, videos, and the like. The display 194 includes a display panel.

In some embodiments, the cell phone 100 may include 1 or N display screens 194, N being a positive integer greater than 1. For example, the cell phone 100 may include 2 display screens 194, a flexible folding screen 194-1 and a display screen 194-2.

When the flexible folding screen 194-1 is a flexible folding screen, the user may fold the flexible folding screen 194-1. For example, referring to fig. 1, the flexible folding screen 194-1 corresponds to the flexible folding screen 103, and when the user folds the flexible folding screen 194-1, the display screen 194 may be divided into two display areas, namely, a display area 1 (first screen) and a display area 2 (second screen). And the flexible folding screen 103 is divided into two display areas with a certain included angle alpha. In a general usage scenario, the flexible folding screen 194-1 may be referred to as a primary screen of the mobile phone 100 and the display screen 194-2 may be referred to as a secondary screen of the mobile phone 100, but is not limited thereto. As another example, the flexible folding screen 194-1 is referred to as the inner screen of the cell phone 100 and the display screen 194 is referred to as the outer screen. The size of the inner screen is typically larger than the size of the outer screen, i.e. the display area of the inner screen is larger than the display area of the outer screen. The external screen may be a screen that operates when the mobile phone 100 is in a folded state. The inner screen may be a larger screen that operates when the mobile phone 100 is in the unfolded state, that is, the display area of the inner screen is larger than the display area of the outer screen.

It will be appreciated that the user may fold the screen along one of the fold lines in the flexible folding screen 194-1. Wherein the position of the fold line may be preset. In other embodiments, the location of the fold line may also be arbitrarily selected by the user in the flexible folding screen 194-1. In the present application, the mobile phone 100 may determine that the flexible folding screen 194-1 is in the unfolded state when the angle α between the flexible folding screen 194-1 and the display screen 194 is greater than a preset angle threshold P (e.g., 170 °). When the angle α between the flexible folding screen 194-1 and the display screen 194 is less than the preset angle threshold P, the mobile phone 100 may determine that the flexible folding screen 194-1 is in the folded state. The physical form of the flexible folding screen 194-1 may be divided into an unfolded state and a folded state in embodiments of the present application. The manner of the preset angle threshold P is described in the foregoing, and will not be described herein.

The processor 110 may control the switch 111 to alternately open the switch 111 to the data transmission channel 1 corresponding to the flexible folding screen 194-1 or the data transmission channel 2 corresponding to the display screen 194-2 to open the data transmission channel 1 or the data transmission channel 2, and then transmit corresponding display data to the corresponding flexible folding screen 194-1 or the display screen 194-2 through the opened data transmission channel 1 or the opened data transmission channel 2, respectively, and display contents corresponding to the display data on the flexible folding screen 194-1 and the display screen 194-2. Wherein the display data may be image data, video data, etc.

In this embodiment, the mobile phone 100 may switch the switch 111 to the data transmission channel 1 corresponding to the flexible folding screen 194-1 or the data transmission channel 2 corresponding to the display screen 194-2 to open the data transmission channel 1 or the data transmission channel 2, and transmit the display data to the flexible folding screen 194-1 and the display screen 194-2 through a display interface 112 for display. In this way, the normal display of the flexible folding screen 194-1 and the display screen 194-2 can be realized only through one display interface 112, so that the multi-screen normal display function of the mobile phone 100 can be satisfied, and the cost of the mobile phone 100 can be reduced.

In a scenario where the user wants the flexible folding screen 194-1 and the display screen 194-2 to be displayed simultaneously, a switch 111 exceeding a preset switching speed may be provided in the mobile phone 100. In this way, the switching speed of the switch 111 is faster, and even if the time for the flexible folding screen 194-1 and the display screen 194-2 to receive the display data has a time difference, the time difference is not distinguished by human eyes, and the display time of the flexible folding screen 194-1 and the display screen 194-2 which are seen by human eyes is basically consistent, so that synchronous display of the flexible folding screen 194-1 and the display screen 194-2 can be realized, and the user experience is further improved.

With the rapid development of mobile terminals, higher requirements are being placed on the bandwidth of the display interface. The mobile industry processor interface (Mobile Industry Processor Interface, MIPI) alliance has therefore proposed the display serial interface (Display Serial Interface, DSI) specification to meet the demands of higher resolution display screens. Display interface 112 may be a component that complies with the DSI interface specification such that when flexible folding screen 194-1 and display screen 194-2 support higher display resolutions, display interface 112 may enable higher resolution displays.

The display interface 112 includes at least a display stream compression part 1121, and the display stream compression part 1121 is used for compressing an image into display data with a certain resolution. Fig. 4 shows a schematic diagram of the structure of the display interface 112. As shown in fig. 4, the display interface 112 may include a display stream compression 11121, an image post-processing 11122, and a graphics layer synthesis 11123.

Display stream compression (Display Stream Compression, DSC) is a low cost, low latency and visually lossless image compression standard for display links, and display stream compression member 11121 may be a device having that standard. The image post-processing member 11122 may be a device with image brightness enhancement. Thus, the display data transmitted through the display interface may have a larger data size/data rate.

The controller can generate operation control signals according to the instruction operation codes and the time sequence signals to finish the control of instruction fetching and instruction execution.

A memory may also be provided in the processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that the processor 110 has just used or recycled. If the processor 110 needs to reuse the instruction or data, it may be called from memory. Repeated accesses are avoided and the latency of the processor 110 is reduced, thereby improving the efficiency of the system.

In some embodiments, the processor 110 may include one or more interfaces. The interface may include an integrated circuit (inter-integrated circuit, I2C) interface, or the like.

It should be understood that the interface connection relationship between the modules illustrated in the embodiments of the present application is a schematic illustration, and does not limit the structure of the mobile phone 100. In other embodiments of the present application, the mobile phone 100 may also use different interfacing manners, or a combination of multiple interfacing manners in the foregoing embodiments.

The charge management module 140 is configured to receive a charge input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charge management module 140 may receive a charging input of a wired charger through the USB interface 130.

The power management module 141 is used for connecting the battery 142, and the charge management module 140 and the processor 110. The power management module 141 receives input from the battery 142 and/or the charge management module 140 to power the processor 110, the internal memory 121, the display 194, the camera 193, the wireless communication module 160, and the like.

The wireless communication function of the mobile phone 100 may be implemented by the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, a modem processor, a baseband processor, and the like.

The handset 100 has a variety of display scenarios. One display scenario is that the handset 100 may display the same content on multiple display screens in a multi-screen display mode. Another display scenario is that the handset 100 may display different content on multiple display screens in a multi-screen display mode. Another display scenario is where the handset 100 may display content on one of a plurality of display screens in a single screen display mode. The following describes the technical scheme of the present application in detail in combination with the above three specific scenarios:

scene 1: in the multi-screen display mode, the flexible folding screen 103 and the display screen 102 which display the same content display scenes on the plurality of display screens synchronously display the same content display scenes

Taking display data as image data, when the flexible folding screen mobile phone 100 is in a fully unfolded state, the user a uses the flexible folding screen mobile phone to further introduce the technical scheme of the application for taking a scene of the user B as an example.

Fig. 5 shows a schematic view of a multi-screen display mode shooting scene. In the photographing scene, after the mobile phone 100 starts the multi-screen display mode, the user a starts the rear camera to shoot the user B, and the folding screen 103 displays the shot picture of the user B in the preview frame of the photographing interface for the user a to see. The display screen 102 also displays the shot picture of the user B in the preview box of the shooting interface for the user B to see. In this way, the content displayed on the flexible folding screen 103 and the content displayed on the display screen 102 are the same, and the two display screens simultaneously display the picture of the user B in the preview frame of the photographing interface, so that both the photographed user and the photographed user can see the preview picture.

The following describes a display method of the mobile phone 100 in the multi-screen display mode. It will be appreciated that the handset 100 has previously turned on the multi-screen display mode prior to performing the following steps. Fig. 6 shows a flow diagram of a display method. As shown in fig. 6, the flow includes the steps of:

Step 601: in response to a first operation of a user, the mobile phone 100 starts the camera to capture the ith frame of image data, and alternately opens the switch to the data transmission channel 1 corresponding to the flexible folding screen 103 or the data transmission channel 2 corresponding to the display screen 102.

The two data transmission channels are respectively in one-to-one correspondence with the flexible folding screen 103 and the display screen 102. The data transmission channel 1 and the data transmission channel 2 are used for transmitting corresponding i-th frame display data to the flexible folding screen 103 and the display screen 102, respectively. In this way, the mobile phone 100 may start the camera to capture image data in response to the first operation of the user, and alternatively open two data transmission channels of the switch in the multi-screen display mode, so as to transmit corresponding image data to the corresponding display screen through the opened data transmission channels, and display corresponding images on the corresponding display screen based on the corresponding image data.

The image data is i-th frame image data, i is sequentially valued in {1,2, … …, N } where N is an integer of 1 or more. Thus, the mobile phone 100 can sequentially display the corresponding ith frame of image, so that the user can see the dynamic preview picture.

The first operation may be a user's opening operation of the camera application. For example, fig. 7 shows a User Interface (UI) change diagram in a scene of turning on a camera. The opening operation of the camera application may be performed on the flexible folding screen 103 or the display screen 102. The following description will be given by taking an example of an operation of the mobile phone 100 in response to a user opening the multi-screen display mode at the flexible folding screen 103. For example, as shown in fig. 7 (a), the first operation may be that the user clicks the camera icon. It will be appreciated that, as shown in fig. 7 (b), the mobile phone 100 starts the camera to capture image data and displays a preview box for displaying a picture captured by the camera in response to the user clicking the camera icon. In some embodiments, the manner in which the mobile phone 100 turns on the multi-screen display mode may be that the mobile phone 100 may tune the mobile phone 100 to the multi-screen display mode in response to a third operation by the user. For example, the setup menu of the mobile phone 100 includes a selection entry of the multi-screen display mode, and the mobile phone 100 may adjust the mobile phone 100 to the multi-screen display mode in response to the user's operation of turning on the multi-screen display mode in the setup. The settings may be system settings or settings in a camera application.

The operation of turning on the multi-screen display mode may be performed on the flexible folding screen 103 or the display screen 102. The following description will be given by taking an example of an operation of the mobile phone 100 in response to a user turning on the multi-screen display mode on the display screen 102. FIG. 8 shows a user interface variation diagram for turning on a multi-screen display mode. As shown in fig. 8 (a), the third operation may be that the user clicks the setting icon; then, in the setting interface shown in fig. 8 (b), clicking the expansion button of the multi-screen display mode; then, in the multi-screen display mode interface shown in the diagram (c) of fig. 8, the display screen requiring multi-screen display is selected in a click manner, and then confirmation is performed by clicking. As shown in fig. 8 (d), the selection item of the multi-screen display mode corresponds to an on state.

It will be appreciated that although figure 8 (c) shows only two alternative displays, in a more (three and more) display device, a user may select any two or more of the displays. Therefore, the user can select the display screen which is wanted to be displayed on multiple screens according to own will, and user experience is improved to a certain extent.

In other embodiments, the mobile phone 100 may also start the multi-screen display mode of the mobile phone 100 in the foregoing manner after the camera is turned on to capture the image data in response to the first operation of the user.

Step 602: the mobile phone 100 transmits the ith frame of image data to the flexible folding screen 103 and the display screen 102 through the data transmission channels 1 and the data transmission channels 1 which are opened alternately, and displays images corresponding to the ith frame of image data on the flexible folding screen 103 and the display screen 102.

The data transmission channel is a data transmission channel between the display interface and the display screen, the mobile phone 100 opens a data transmission channel corresponding to a certain display screen, so that corresponding image data can be transmitted to the corresponding display screen through the channel, and the display screen 102 and the flexible folding screen 103 of the mobile phone 100 receive the corresponding image data, so that corresponding images can be displayed based on the image data. For example, as shown in fig. 5, the mobile phone 100 displays the shot screen of the user B in the preview box of the shooting interface of the display screen 102 and the flexible folding screen 103.

It is understood that the display parameters of the display screen include various display attribute information of the image data, such as resolution, brightness, and the like. The mobile phone 100 may transmit image data of the corresponding display parameters to the corresponding display screen through the opened data transmission channel.

The display parameters of the images to be displayed by the flexible folding screen 103 and the display screen 102 may be different or the same.

In some embodiments, if the display parameters of the images to be displayed by the flexible folding screen 103 and the display screen 102 are the same, the mobile phone 100 may prepare image data of one display parameter. Then, the mobile phone 100 transmits the image data of the corresponding display parameters to the corresponding display screen through the alternately opened data transmission channels. Specifically, when the flexible folding screen 103 and the display screen 102 are displayed synchronously, if the display parameters of the flexible folding screen 103 and the display screen 102 are identical, only the image data of one display parameter is prepared, then the image data of the display parameter are respectively sent to the corresponding two display screens through the two data channels for display, and specifically, only the image data to be displayed is required to be switched to the display screen corresponding to the corresponding data channel for display according to the preset time interval.

In some embodiments, if the display parameters of the images to be displayed on the flexible folding screen 103 and the display screen 102 are different, the mobile phone 100 needs to sequentially prepare the image data of the two display parameters. The mobile phone 100 firstly switches the switch to a data channel, and transmits the prepared image data of one display parameter to the display screen corresponding to the data channel for display. In the process of displaying images on the display screen, the mobile phone 100 prepares image data of another display parameter, switches the switch to another data transmission channel after the image data of the display parameter is ready, and transmits the image data of the other display parameter to the display screen corresponding to the data channel for displaying.

In this scheme, even if the display times of the images corresponding to the image data of the two display parameters are different, the difference in the display times is indistinguishable to the human eye, and the display times of the two display parameters seen by the human eye are substantially identical. In this way, in a scenario where the user wants to synchronously display two display screens, the mobile phone 100 with one display interface supporting the two display screens can synchronously display, thereby improving the user experience.

Specifically, fig. 9 shows a flow chart of a display method. As shown in fig. 9, the flow includes the steps of:

step 901: the mobile phone 100 receives a first operation of a user.

The first operation in this step is the same as the first operation described above, and will not be described here again.

Step 902: the mobile phone 100 acquires the ith frame of image data of the first display parameters, opens the switch to the data transmission channel 1 corresponding to the flexible folding screen 103, sends the ith frame of image data of the first display parameters to the flexible folding screen 103 through the data transmission channel 1, and the flexible folding screen 103 displays the ith frame of image corresponding to the ith frame of image data with the first display parameters.

i may be sequentially valued in {1,2, … …, N } where N is an integer of 1 or more. The value of N can be determined according to actual conditions.

For example, fig. 10 shows a schematic diagram of a flexible folding screen 103 and a display screen 102 displaying images of different display parameters simultaneously. As shown in fig. 10, P1 corresponds to the number of the 1 st frame image, P2 corresponds to the number of the 2 nd frame image, P3 corresponds to the number of the 3 rd frame image, and PN corresponds to the number of the N th frame image.

The mobile phone 100 obtains the 1 st frame of image data of the first display parameter, opens the switch to the data transmission channel 1 corresponding to the flexible folding screen 103, sends the 1 st frame of image data of the first display parameter to the flexible folding screen 103 through the data transmission channel 1, and starts to display the P1 st frame of image of the first display parameter at 00:05 after the flexible folding screen 103 receives the P1 st frame of image data of the first display parameter.

Step 903: the flexible folding screen 103 determines the i-th frame image data of the second display parameter in the period 1 after the start of displaying the i-th frame image.

The cellular phone 100 may prepare the i-th frame image data of the second display parameter for the period 1 to determine the i-th frame image data of the second display parameter. It is understood that the period 1 may be set according to actual conditions.

For example, as shown in fig. 10, the mobile phone 100 re-initializes the display parameters of the P1 frame image data, initializes the P1 frame image data to the image data of the second display parameters, and requires 1-2 frames of time for initialization, for example, 2 frames of time for initialization, and the 2 frames of time is 0.1s.

Step 904: after the flexible folding screen 103 displays the ith frame of image in the time period 1, the switch is turned on to the data transmission channel 2 corresponding to the display screen 102, the ith frame of image data of the second display parameter is sent to the display screen 102 through the data transmission channel 2, and the display screen 102 displays the ith frame of image corresponding to the ith frame of image data with the second display parameter.

For example, as shown in fig. 10, after the flexible folding screen 103 displays the 1 st frame image within 0.1s, the mobile phone 100 switches the switch to the data transmission channel 2, transmits the P1 frame image data of the second display parameter to the display screen 102 through the data transmission channel 2, the display screen 102 updates the image, and starts displaying the P1 frame image corresponding to the P1 frame image data with the second display parameter at 00:15.

Step 905: i is taken as i+1, and the display screen 102 determines the i-th frame image data of the first display parameter in the period 1 after the start of displaying the i-th frame image, and goes to step 901.

Taking i +1 indicates that the handset 100 will continue to display the next frame of image on the flexible folding screen 103 and the display screen 102.

The cellular phone 100 may prepare the i-th frame image data of the first display parameter for the period 1 to determine the i-th frame image data of the first display parameter.

i can be sequentially valued in {1,2, … …, N }, and after the flexible folding screen 103 and the display screen 102 display the 1 st frame of image, the mobile phone 100 will continue to display the next frame of image on the flexible folding screen 103 and the display screen 102 until the nth frame of image is displayed.

If i is 1, i is equal to 2 when i is equal to i+1, and the mobile phone 100 will continue to display the 2 nd frame image on the flexible folding screen 103 and the display screen 102.

For example, as shown in fig. 10, after the display screen 102 is refreshed, the mobile phone 100 re-initializes the display parameters of the P2 frame image data, initializes the P2 frame image data to the image data of the first display parameter, and requires 1-2 frames of time for initialization, for example, 2 frames of time for initialization, and the 2 frames of time is 0.1s.

After the display screen 102 displays the ith frame of image within 0.1s, the mobile phone 100 switches the switch to the data transmission channel 1, transmits the P2 frame of image data of the first display parameter to the flexible folding screen 103 through the data transmission channel 1, the flexible folding screen 103 updates the image, and starts to display the P2 frame of image corresponding to the P2 frame of image data with the second display parameter at 00:25.

The switching speed of the switch is faster, the time of receiving image data by different display screens has a time difference of 0.1s, the time difference is indistinguishable by human eyes, and the display time of a plurality of display screens seen by human eyes is basically consistent, so that synchronous display of the display screens can be realized, and the user experience is further improved.

In some embodiments, if the resolutions in the display parameters are different. For example, the flexible folding screen 103 corresponds to a first resolution, the display screen 102 corresponds to a second resolution, and the first resolution is different from the second resolution. The handset 100 causes the two displays to be displayed simultaneously by:

The mobile phone 100 switches the switch to the data transmission channel 1, and transmits image data of a first resolution to the flexible folding screen 103 through the data transmission channel 1, and the flexible folding screen 103 displays an image of the first resolution based on the image data of the first resolution; the mobile phone 100 switches the switch to the data transmission channel 2, and transmits the image data of the second resolution to the display screen 102 through the data transmission channel 2, and the display screen 102 displays the image of the second resolution based on the image data of the second resolution.

It will be appreciated that the time at which each frame of image data starts to be transmitted may be controlled by a tear signal (Tearing Effect Signal, TE) (output by the display screen). The TE is a feedback signal from the display screen to the processor, and is transmitted through the display interface 112, when the processor receives the TE, the processor starts to transmit corresponding image data to the display screen, the display screen updates the display content, the display content corresponding to the image data is displayed, and the refresh rate is determined by the speed of updating the display content. For example, fig. 11 shows a schematic diagram of TE control of image data transmission time. As shown in fig. 11, the TE may be a feedback signal from the flexible folding screen 103 to the mobile phone 100, and when the mobile phone 100 receives the TE through the display interface 112, it starts to transmit corresponding image data to the flexible folding screen 103, and the flexible folding screen 103 updates the display content and displays the display content corresponding to the image data. The TE may be a feedback signal from the display 102 to the mobile phone 100, and when the mobile phone 100 receives the TE through the display interface 112, it starts to transmit corresponding image data to the display 102, and the display 102 updates the display content and displays the display content corresponding to the image data.

In some embodiments, if the first resolution is the same as the second resolution, the refresh rate of both flexible folding screen 103 and display screen 102 is the frequency of TE divided by 2. For example, in the case of the multi-screen display mode, if the resolution and other display parameters of the flexible folding screen 103 and the display screen 102 are identical, the mobile phone 100 may determine that the TE frequency is 120Hz at the software layer (upper layer), and the refresh rate of the flexible folding screen 103 and the display screen 102 is 60Hz.

In some embodiments, if the first resolution is different from the second resolution, the first resolution is greater than the second resolution, and the refresh rate of the pictures of the flexible folding screen 103 and the display screen 102 is obtained by the following formula:

X＝A/2/(1+B)，

where X represents the refresh rate of the pictures of the flexible folding screen 103 and the display screen 102, a represents the frequency of TE, and B represents the number of switched image frames required to configure the image data of the second resolution.

For example, FIG. 12 shows a schematic diagram of refresh rates of a flexible folding screen 103 and a display screen 102. As shown in fig. 12, the mobile phone 100 determines that the TE frequency is 120Hz at the software layer (upper layer), the number of image frames to be switched required for configuring the image data of the second resolution is 2 frames, and the foregoing data is substituted into the above formula, and the refresh rates of the flexible folding screen 103 and the display screen 102 are 20Hz.

For example, as shown in fig. 12, the refresh rate of the flexible folding screen 103 and the display screen 102 is 20Hz, and the display time per frame of image is 0.05 seconds(s).

The mobile phone 100 obtains the 1 st frame of image data of the first display parameter, opens the switch to the data transmission channel 1 corresponding to the flexible folding screen 103, sends the 1 st frame of image data of the first display parameter to the flexible folding screen 103 through the data transmission channel 1, and starts to display the P1 st frame of image of the first display parameter at 00:05 after the flexible folding screen 103 receives the P1 st frame of image data of the first display parameter. Then, the mobile phone 100 re-initializes the display parameters of the P1 frame image data, initializes the P1 frame image data to the image data of the second display parameters, and requires 1-2 frames of time for initialization, for example, 2 frames of time for initialization, and the 2 frames of time is 0.1s.

After the flexible folding screen 103 displays the 1 st frame of image within 0.1s, the mobile phone 100 switches the switch to the data transmission channel 2, transmits the P1 frame of image data of the second display parameter to the display screen 102 through the data transmission channel 2, the display screen 102 updates the image, and starts to display the P1 frame of image corresponding to the P1 frame of image data with the second display parameter at 00:15.

After the display 102 is refreshed, the mobile phone 100 re-initializes the display parameters of the P2 frame image data, initializes the P2 frame image data to the image data with the first display parameters, and requires 1-2 frames of time during initialization, for example, requires 2 frames of time during initialization, and the time of 2 frames is 0.1s.

i can be sequentially valued in {1,2, … …, N }, and after the flexible folding screen 103 and the display screen 102 display the 1 st frame of image, the mobile phone 100 will continue to display the image on the flexible folding screen 103 and the display screen 102 until the nth frame of image is displayed.

In this scheme, the switching speed of switch 111 is faster, and the time that different display screens received image data has 0.1s time difference, and this time difference is that the people's eye can't discern, and the display time of a plurality of display screens that people's eye was seen is unanimous basically to this can realize a plurality of display screens synchronous display, further improves user experience.

Scene 2: in the multi-screen display mode, the flexible folding screen 103 and the display screen 102 which display different contents on a plurality of display screens display scenes of different display contents

A display method in which the flexible folding screen 103 and the display screen 102 display different display contents in the multi-screen display mode of the mobile phone 100 is described below. In the scheme, different display contents are respectively displayed on the plurality of display screens, so that the use experience of a user is improved.

Fig. 13 shows a flow chart of a display method. As shown in fig. 13, the flow includes the steps of:

step 1301: in response to a first operation of the user, the mobile phone 100 starts the camera to capture two sets of image data, and alternately opens the switch to the data transmission channel 1 corresponding to the flexible folding screen 103 or the data transmission channel 2 corresponding to the display screen 102.

The two data transmission channels are respectively in one-to-one correspondence with the flexible folding screen 103 and the display screen 102. In this way, the mobile phone 100 may start the camera to capture image data in response to the first operation of the user, and alternatively open two data transmission channels of the switch in the multi-screen display mode, so as to transmit corresponding image data to the corresponding display screen through the opened data transmission channels, and display corresponding images on the corresponding display screen based on the corresponding image data.

The first operation may be an operation in which the user turns on a multi-screen display of a picture selected from the album application.

The operation of the user to turn on the multi-screen display of the picture selected from the album application may be performed on the flexible folding screen 103 or the display screen 102. The following description will be given by taking an example of an operation of the mobile phone 100 in response to a user turning on the multi-screen display mode on the display screen 102. For example, FIG. 14 illustrates a user interface change diagram in a picture-on-multi-screen display scenario in which a user has selected from an album application. As shown in fig. 14 (a), the first operation may be that the user selects a plurality of pictures, clicks on a column of the multi-screen display in more, and determines a specific display manner of the multi-screen display, for example, as shown in fig. 14 (B), a flexible folding screen 103 corresponding to the a picture is checked, and a display screen 102 corresponding to the B picture is checked. Thus, the mobile phone 100 can display the selected a picture in the flexible folding screen 103, and display the selected B picture in the display screen 102.

Step 1302: the mobile phone 100 alternately transmits a corresponding one of the two sets of image data to the flexible folding screen 103 and the display screen 102 through the data transmission channel 1 and the data transmission channel 1 which are opened alternately, and displays two images corresponding to the two sets of image data on the flexible folding screen 103 and the display screen 102.

The data transmission channel is a data transmission channel between the display interface and the display screen, the mobile phone 100 opens a data transmission channel corresponding to a certain display screen, so that corresponding image data can be transmitted to the corresponding display screen through the channel, and the display screen 102 and the flexible folding screen 103 of the mobile phone 100 receive corresponding image data, so that different display contents can be displayed on the flexible folding screen 103 and the display screen 102 respectively based on the two groups of image data. For example, FIG. 15 illustrates a schematic view of a user opening a picture selected from an album application to a multi-screen display scene. In this scenario, the cell phone 100 displays the selected a picture in the flexible folding screen 103 and the selected B picture in the display screen 102.

It will be appreciated that the display parameters of the display screen include various display attribute information of the image data, such as resolution, brightness, etc., and the mobile phone 100 may transmit the image data of the corresponding display parameters to the corresponding display screen through the opened data transmission channel.

In some embodiments, if the display parameters (e.g., resolution) of the images to be displayed on the flexible folding screen 103 and the display screen 102 are the same, the mobile phone 100 may prepare two sets of image data with the same parameters, and the mobile phone 100 transmits the two sets of image data with the same parameters to the flexible folding screen 103 and the display screen 102 through the data transmission channels that are opened alternately, so that the different display contents are displayed on the flexible folding screen 103 and the display screen 102.

In some embodiments, if the display parameters of the images to be displayed by the flexible folding screen 103 and the display screen 102 are different, for example, the resolutions are different, two sets of image data with different display parameters are transmitted by different data transmission channels.

In some embodiments, if the display parameters of the images to be displayed by the flexible folding screen 103 and the display screen 102 are different, for example, the resolutions are different, then the mobile phone 100 needs to prepare two sets of image data with two display parameters for two sets of image data with different display parameters transmitted by different data transmission channels. Then, the mobile phone 100 transmits two sets of image data with different display parameters to the flexible folding screen 103 and the display screen 102 through the data transmission channels which are opened alternately, and different pictures are displayed on the flexible folding screen 103 and the display screen 102 with different display parameters.

Specifically, when the display parameters of the flexible folding screen 103 and the display screen 102 are different, the mobile phone 100 needs to sequentially prepare two sets of image data of the two display parameters. The mobile phone 100 firstly switches the switch to a data channel, and transmits a set of image data of a prepared display parameter to a display screen corresponding to the data channel for display. At this time, the mobile phone 100 prepares the image data of another display parameter, switches the switch to another data transmission channel after the set of image data of the display parameter is ready, and transmits the set of image data of the display parameter to the display screen corresponding to the data channel for display. In the case where N in fig. 9 is 1, the detailed description is given above, and the detailed description is omitted here.

In this scheme, even if the display times of the image data of the two display parameters (e.g., resolutions) are different, the difference in display times may be indistinguishable to the human eye, and the display times of the two display parameters (e.g., resolutions) seen by the human eye are substantially identical. In this way, in a scenario where the user wants to synchronously display two display screens, the mobile phone 100 with one display interface supporting the two display screens can synchronously display, thereby improving the user experience.

In some embodiments, if the mobile phone 100 transmits the image data with the corresponding resolution to the corresponding display screen through the opened data transmission channel, the mobile phone 100 displays the image with the corresponding resolution on the corresponding display screen based on the image data with the corresponding resolution.

In some embodiments, the flexible folding screen 103 corresponds to a first resolution, the display screen 102 corresponds to a second resolution, the switch is switched to the data transmission channel 1, first image data of the first resolution is transmitted to the flexible folding screen 103 through the data transmission channel 1, and the flexible folding screen 103 displays a first image of the first resolution based on the first image data of the first resolution; the switch is switched to the data transmission channel 2, and the second image data of the second resolution is transmitted to the display screen 102 through the data transmission channel 2, and the display screen 102 displays the second image of the second resolution based on the second image data of the second resolution.

In some embodiments, if the first resolution is the same as the second resolution, the refresh rate of both flexible folding screen 103 and display screen 102 is the frequency of TE divided by 2. In some embodiments, if the first resolution is different from the second resolution, the first resolution is greater than the second resolution, and the refresh rate of the pictures of the flexible folding screen 103 and the display screen 102 is obtained by the following formula:

X＝A/2/(1+B)，

For example, the mobile phone 100 determines that the TE frequency is 120Hz at the software layer (upper layer), the number of image frames for switching required for configuring the image data of the second resolution is 2 frames, and the foregoing data is substituted into the above formula, and the refresh rates of the flexible folding screen 103 and the display screen 102 are 20Hz.

Fig. 16 shows a schematic diagram of a flexible folding screen 103 and a display screen 102 displaying images of different resolutions simultaneously. As shown in fig. 10, the refresh rate of the flexible folding screen 103 and the display screen 102 is 20Hz, and the display time per frame of image is 0.05 seconds(s).

When the flexible folding screen 103 receives image data of the first resolution picture a at 00:05, the display of the first resolution image starts at 00:05. Then, the mobile phone 100 performs resolution re-initialization on the image data of the picture a, initializes the image data of the picture a to the image data of the second resolution, and requires 1-2 frames of time for initialization, for example, 2 frames of time for initialization, and the 2 frames of time is 0.1s.

After 0.1s, the image data of the picture a with the second resolution is ready, the mobile phone 100 switches the switch 111 to the data transmission channel 2, the image data of the picture a with the second resolution is transmitted to the display screen 102 through the data transmission channel 2, the display screen 102 updates the display content, and the display content corresponding to the image data of the picture a with the second resolution is displayed at the beginning of 00:15.

Scene 3: in the single-screen display mode, a display scene of content is displayed on one of a plurality of display screens

The following describes a display method of the mobile phone 100 in the single-screen display mode. Fig. 17 shows a flow diagram of a display method. As shown in fig. 17, the flow includes the steps of:

step 1701: the mobile phone 100 responds to the second operation of the user to acquire the image data, and opens the switch to a target data transmission channel corresponding to a target display screen, wherein the target display screen is any one of a plurality of display screens.

The target data transmission channel corresponds to the target display screen. In this way, the mobile phone 100 may obtain the image data in response to the second operation of the user, in the single-screen display mode, turn on the switch to the target data transmission channel corresponding to the target display screen, so as to transmit the corresponding target image data to the corresponding target display screen through the opened target data transmission channel, and then display the image corresponding to the target image data on the corresponding target display screen.

In one scenario, the second operation may be a user's start operation of the camera application. For example, as shown in fig. 7 (a), the second operation may be that the user clicks the camera icon, and the mobile phone 100 starts the camera to capture image data in response to the user clicking the camera icon.

In some embodiments, the mobile phone 100 may turn on the single-screen display mode in such a way that the mobile phone 100 may tune the mobile phone 100 to the single-screen display mode in response to the third operation of the user. For example, the setting menu of the mobile phone 100 includes a selection item of the single-screen display mode, and the mobile phone 100 may tune the mobile phone 100 to the single-screen display mode in response to an operation of turning on the single-screen display mode in the setting by the user. The settings may be system settings or settings in a camera application.

The operation of turning on the single-screen display mode may be performed on the flexible folding screen 103 or the display screen 102. The following description will be given by taking an example of an operation of the mobile phone 100 in response to a user turning on the multi-screen display mode on the display screen 102. FIG. 18 shows a user interface variation diagram for turning on a single screen display mode. As shown in fig. 18 (a), the third operation may be that the user clicks the setting icon; then, in the setting interface shown in fig. 18 (b), the expansion button of the single-screen display mode is clicked; then, in the single-screen display mode interface shown in fig. 18 (c), a display screen that needs to be displayed on a single screen is selected in a clicking manner, for example, a selection control corresponding to the flexible folding screen 103 is clicked, and then confirmation is clicked. As shown in fig. 18 (d), the selection item of the single screen display mode corresponds to an on state. The user can select the display screen which wants to be displayed on the single screen according to own will, so that the user experience is improved to a certain extent. For another example, FIG. 19 illustrates a user interface variation diagram of a single screen selection. As shown in fig. 19, the user may also click on a selection control corresponding to the display screen 102, so that the display screen 102 may be determined to be the target display screen in the single-screen display mode.

In other embodiments, the mobile phone 100 may also start the single-screen display mode of the mobile phone 100 after acquiring the image data in response to the second operation of the user in the foregoing manner.

The target display screen is any one of the display screen 102 and the flexible folding screen 103. When the display screen 102 is displayed separately, the mobile phone 100 switches to a data transmission channel connected with the display screen 102; when the flexible folding screen 103 is displayed alone, the mobile phone 100 switches to a data transmission channel connected to the flexible folding screen 103.

Step 1702: the mobile phone 100 transmits the image data to the target display screen through the target data transmission channel, and displays the display content corresponding to the image data on the target display screen.

The target display screen is any one of the display screen 102 and the flexible folding screen 103. When the display 102 is displayed alone, the mobile phone 100 switches to a data transmission channel connected to the display 102, and the mobile phone 100 transmits the target image data to the target display through the opened target data transmission channel. When the flexible folding screen 103 is displayed alone, the mobile phone 100 switches to a data transmission channel connected to the flexible folding screen 103, and the mobile phone 100 transmits target image data to the target display screen through the opened target data transmission channel to display a target image based on the target image data on the target display screen.

The target display screen is any one of the display screen 102 and the flexible folding screen 103. The target display of the mobile phone 100 receives the corresponding image data, and can display the corresponding image based on the image data. For example, fig. 20 shows a schematic view of a single-screen display mode shooting scene. Thus, in the photographing scene, the flexible folding screen 103 is a target display screen in the single-screen display mode. After the mobile phone 100 starts the single-screen display mode, the user a starts the rear camera to shoot the user B, and the flexible folding screen 103 displays the shot picture of the user B in the preview frame of the shooting interface for the user a to see. And the display screen 102 does not display the photographed picture of the user B in the preview box of the photographing interface.

The display methods in the multi-screen display mode and in the single-screen display mode are described above, respectively. It will be appreciated that the switching state of the switch depends on the display mode. Both of the above display modes may exist in the mobile phone 100, and the mobile phone 100 may execute the display method in the corresponding mode after determining which display mode the mobile phone 100 is in.

The technical solution of the embodiments of the present application is mainly described above by taking image data as an example. In other embodiments, if the plurality of display screens play the video, the mobile phone 100 can switch to the data transmission channels corresponding to the different display screens to open the corresponding data transmission channels, and transmit the video data to the plurality of display screens for playing through one display interface. In this way, the normal multi-screen display can be realized only through one display interface, so that the normal multi-screen display function of the mobile phone 100 can be met, and the cost of the mobile phone 100 can be reduced.

The software system of the mobile phone 100 may employ a layered architecture, an event driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. In the embodiment of the invention, taking an Android system with a layered architecture as an example, a software structure of the mobile phone 100 is illustrated.

Fig. 21 is a block diagram showing a software configuration of the mobile phone 100 according to the embodiment of the present invention.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 21, the application layer package may include applications such as cameras, gallery, calendar, talk, map, navigation, WLAN, bluetooth, music, video, short message, etc.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: a surface manager (surface manager), a hardware composition abstraction layer (HardwareComposer, HWC), a Media library (Media Libraries), a three-dimensional graphics processing library (e.g., openGL ES), a 2D graphics engine (e.g., SGL), etc.

A surface manager (surfeflinger) is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications. The surface manager is responsible for managing a Frame Buffer (Frame Buffer) of the Android system, the display screen of the Android device is abstracted into a Frame Buffer, and the surface manager service in the Android system draws a user interface in the application program by writing content into the Frame Buffer.

The surface manager includes a composition engine (Composition Engine). In the embodiment of the present application, in the composition engine of the surface manager, the plurality of display screens correspond to a plurality of display device (DisplayDevice) modules. For example, as shown in fig. 22, two display screens correspond to two display device modules: a display device 1 and a display device 2.

The surface manager provides all soft layer information to the hardware composition abstraction layer (HardwareComposer, HWC), asking for its way of processing. In the embodiment of the application, in the hardware combination abstract layer of the surface manager, a plurality of display screens correspond to a plurality of display equipment modules. For example, as shown in fig. 22, two display screens correspond to two display device modules: a display device 1 and a display device 2.

The hardware composition abstract layer decides whether to use a hardware layer synthesizer or GPU synthesis according to the hardware performance, the surface manager processes a soft layer which needs GPU synthesis, the result is submitted to the hardware composition abstract layer for display, and the soft layer which needs hardware layer synthesizer synthesis is processed by the hardware composition abstract layer.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver. In the embodiment of the application, in the display driving of the kernel layer, the plurality of display screens correspond to the plurality of display equipment modules. For example, as shown in fig. 22, two display screens correspond to two display device modules: a display device 1 and a display device 2.

The display drive is used for driving the data transmission channel of the switch change-over switch so that the plurality of display screens display the display method of the embodiment of the application.

The following is a two-screen display scenario illustrating the workflow of the handset 100 software and hardware.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the sensor driver of the kernel layer. The sensor driver processes the touch operation into raw input events (including information of touch coordinates, time stamp of touch operation, etc.). The raw input events are stored at the sensor driver. The application framework layer acquires an original input event from the sensor driver and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, the control corresponding to the click operation is a control of a camera application icon as an example, the camera application invokes an interface of an application framework layer, starts the camera application, starts a camera driver, and captures static display data through the camera 193. After the camera application is started, in the multi-screen display mode, the mobile phone 100 alternately transmits the ith frame of image data to the flexible folding screen 103 and the display screen 102 through the data transmission channels 1 and the data transmission channels 1 which are alternately opened: when the data transmission channel 1 is opened, calling a display content container 1 of a window manager, a logic display 1 of the display manager, a display device 1 of a surface manager and the display device 1 in a hardware combination abstract layer, and then calling the display device 1 in a display drive to drive a flexible folding screen 103 to display shooting content; when the data transmission channel 2 is opened, the display content container 2 of the window manager, the logic display 2 of the display manager, the display device 2 of the surface manager and the display device 2 in the hardware combination abstract layer are called, and after the display device 2 in the display drive is called, the display screen 102 is driven to display shooting content, so that images corresponding to the ith frame of image data are displayed on the flexible folding screen 103 and the display screen 102.
