Description

Technical Field

[0001] At least one embodiment of the present disclosure relates to a control method and control system for a display screen, an electronic device, and a storage medium. Background Art

[0002] The sizes of current in-vehicle display screens are either fixed or adjustable. For an in-vehicle display screen with an adjustable size, for example, the screen can be retracted into a storage device by means of stretching or curling, and the size of the display screen extended outside the storage device can be controlled as needed, so as to control the size of the display screen participating in the display. For another example, by controlling the display screen to stretch longitudinally or horizontally, the size of the display area in which the display screen participates in the display can be changed to meet different needs of users.

[0003] Currently, some vehicles are equipped with only one display screen, and some vehicles are equipped with multiple display screens. For example, there is a main driver screen near the driver's seat and a co-driver screen near the co-driver's seat. The main driver screen is mostly used to display road conditions information, navigation information and other information related to controlling driving for the driver, and the co-driver screen is mostly used for entertainment functions.

[0004] In addition, the sizes of in-vehicle display screens are diverse and different. It is difficult for application software manufacturers to perform adaptation development for most in-vehicle display screens so that the interface size of the application software matches the size of the in-vehicle display screen.

[0016] For example, in the control method of a display screen provided by an embodiment of the present disclosure, the type of the target application includes at least one of a multimedia application, a short video application, a navigation application, a social application, and a shopping application.

[0017] For example, in the control method of a display screen provided by an embodiment of the present disclosure, the control method of the display screen includes: obtaining the maximum aspect ratio and the minimum aspect ratio of the display screen. Wherein, if the type of the target application is a multimedia application, the preset aspect ratio is the maximum aspect ratio, and the control method of the display screen includes: adjusting the aspect ratio of the display screen to the maximum aspect ratio; if the type of the target application is a short video application, the preset aspect ratio is the minimum aspect ratio, and the control method of the display screen includes: adjusting the aspect ratio of the display screen to the minimum aspect ratio; if the type of the target application is a navigation application, the value of the preset aspect ratio is between the minimum aspect ratio and the maximum aspect ratio, and the control method of the display screen includes: making the value of the aspect ratio of the adjusted display screen between the minimum aspect ratio and the maximum aspect ratio.

[0018] For example, in the control method of a display screen provided by an embodiment of the present disclosure, if the type of the target application is a multimedia application, the control method of the display screen includes: determining whether the display screen is longitudinally scalable. If so, adjusting the aspect ratio of the display screen to a third preset aspect ratio corresponding to the multimedia application, where the third preset aspect ratio is greater than 1. If not, obtaining the maximum aspect ratio of the display screen and adjusting the aspect ratio of the display screen to the maximum aspect ratio.

[0019] For example, in the control method of a display screen provided by an embodiment of the present disclosure, if the type of the target application is a short video application, the control method includes: determining whether the display screen is longitudinally scalable; if so, adjusting the aspect ratio of the display screen to a fourth preset aspect ratio corresponding to the short video application, where the fourth preset aspect ratio is less than 1; if not, obtaining the minimum aspect ratio of the display screen and adjusting the aspect ratio of the display screen to the minimum aspect ratio.

[0020] For example, in the control method of a display screen provided by an embodiment of the present disclosure, if the type of the target application is a multimedia application, the control method includes: determining the playback history of the multimedia application; and obtaining the aspect ratio of the multimedia content in the playback history as the preset aspect ratio.

[0023] For example, in the control method of a display screen provided by an embodiment of the present disclosure, the control method includes: obtaining the aspect ratio adjustment range of the display screen, where the range of the aspect ratio of the display screen is a to b (a < b), a is the minimum value of the aspect ratio of the display screen, and b is the maximum value of the aspect ratio of the display screen; obtaining the aspect ratio adapted by the target application and comparing it with the range of the aspect ratio of the display screen; if the aspect ratio adapted by the target application is greater than b, using b as the preset aspect ratio; if the aspect ratio adapted by the target application is less than a, using a as the preset aspect ratio and adjusting the aspect ratio of the display screen to a; if the aspect ratio adapted by the target application is greater than a and less than b, using the aspect ratio adapted by the target application as the preset aspect ratio.

[0024] For example, in the control method of a display screen provided by an embodiment of the present disclosure, the control method includes: after adjusting the aspect ratio of the display screen according to the preset aspect ratio, performing the following steps: obtaining the aspect ratio of the display screen of the target application as the content aspect ratio, and further adjusting the aspect ratio of the display screen to the content aspect ratio.

[0027] For example, in the control method of a display screen provided by an embodiment of the present disclosure, at least one of the horizontal size and the vertical size of the display screen is adjustable so that the aspect ratio of the picture displayed on the display screen is adjustable.

[0028] For example, in the control method of a display screen provided by an embodiment of the present disclosure, a plurality of sub-display screens are spliced together to form the display screen, and the plurality of sub-display screens are respectively used to display corresponding target applications; the control method includes: judging whether the target applications displayed by the plurality of sub-display screens are associated with each other. If the target applications respectively displayed by the plurality of sub-display screens are associated with each other, then synchronously adjust the horizontal size and / or the vertical size of the plurality of sub-display screens respectively, so that the aspect ratio of the display screen formed by splicing the plurality of sub-display screens together is the target aspect ratio; if the target applications of the plurality of sub-display screens or the content of the target applications respectively displayed are independent of each other, then each sub-display screen is used as an independent display screen, and the aspect ratio of each sub-display screen is adjusted respectively according to the preset aspect ratio of the application used by each sub-display screen so that the value of the aspect ratio of the sub-display screen reaches its respective target aspect ratio.

[0029] For example, in the control method of a display screen provided by an embodiment of the present disclosure, when the target applications are associated with each other and the horizontal size and / or the vertical size of the plurality of sub-display screens are synchronously adjusted respectively so that the aspect ratio of the display screen formed by splicing the plurality of sub-display screens together is the target aspect ratio, the displayed contents are associated with each other.

[0030] For example, in the control method of a display screen provided by an embodiment of the present disclosure, the horizontal dimensions and / or vertical dimensions of the plurality of sub-display screens are synchronously adjusted respectively so that the height of the entire display screen remains consistent in the longitudinal direction along the horizontal direction.

[0031] For example, in the control method of a display screen provided by an embodiment of the present disclosure, after adjusting the aspect ratio of the display screen, the target application is started.

[0032] At least one embodiment of the present disclosure further provides a display screen control system, which includes: a target attribute judgment module, an aspect ratio acquisition module, an aspect ratio adjustment control module, and a display screen driving device.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0056] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art to which the present invention pertains. The terms "first", "second", and similar terms used in the specification and claims of this patent application for the present invention do not denote any order, quantity, or importance, but are only used to distinguish different components. The terms "including" or "comprising" and the like mean that the technical features appearing before the term cover the technical features enumerated after the term and their equivalents, without excluding other technical features.

[0057] When the size of the display area participating in the display of the display screen does not match the size of the interface of the application software used, it will greatly affect the user's viewing experience. This problem also exists for in-vehicle display screens. The sizes of in-vehicle display screens are diverse and different, and it is difficult for application software manufacturers to develop adaptations for most in-vehicle display screens so that the interface size of the application software matches the size of the in-vehicle display screen. Therefore, in order to improve the display effect and user experience of in-vehicle display screens, a vehicle-mounted display system that can adapt the interface size of the application software to the size of the in-vehicle display screen is needed.

[0058] At least one embodiment of the present disclosure provides a control method for a display screen. The control method includes: determining a target attribute satisfied by a target application, where the target attribute corresponds to a preset aspect ratio; obtaining the preset aspect ratio; and adjusting the aspect ratio of the display screen according to the preset aspect ratio so that the value of the aspect ratio of the display screen reaches a target aspect ratio. The aspect ratio of the display screen is the ratio of the horizontal size to the vertical size of the display area of the display screen, and the vertical intersects with the horizontal. For example, the control method of the display screen can be used for an in-vehicle display screen. In the control method of the display screen provided by the embodiments of the present disclosure, the aspect ratio of the display screen is directly adjusted according to the preset aspect ratio corresponding to the target attribute satisfied by the target application to be displayed on the display screen. The preset aspect ratio is existing and already present. Therefore, the method of adjusting the aspect ratio of the display screen is simple and efficient, and can quickly match the aspect ratio of the display screen with the aspect ratio of the interface of the application software (i.e., the target application) that the user wants to use the display screen to display, reducing the gap between the aspect ratio of the display screen and the aspect ratio of the interface of the target application, and even making the two equal, thus improving the user experience.

[0059] At least one embodiment of the present disclosure further provides a display screen control system. The display screen control system includes: a target attribute determination module, an aspect ratio acquisition module, an aspect ratio adjustment control module, and a display screen driving device. The target attribute determination module is configured to determine the target attribute satisfied by the target application, and the target attribute corresponds to a preset aspect ratio. The aspect ratio acquisition module is configured to obtain the preset aspect ratio. The display screen driving device is signal-connected to the aspect ratio adjustment control module, and the aspect ratio adjustment control module is configured to control the display screen driving device to drive the display screen to expand or contract in at least one of the horizontal and vertical directions according to the preset aspect ratio, so as to adjust the aspect ratio of the display screen, so that the value of the aspect ratio of the display screen reaches a target aspect ratio. The aspect ratio of the display screen is the ratio of the horizontal size to the vertical size of the display area of the display screen, and the vertical intersects with the horizontal.

[0060] At least one embodiment of the present disclosure further provides an electronic device. The electronic device includes: one or more processors and a storage device. The storage device is used to store one or more programs. When the one or more programs are executed by the one or more processors, the one or more processors implement any control method of the display screen provided by the embodiments of the present disclosure.

[0061] At least one embodiment of the present disclosure further provides a storage medium containing computer-executable instructions. The computer-executable instructions are used to execute any control method of the display screen provided by the embodiments of the present disclosure when executed by a computer processor.

[0062] Exemplarily, Figure 1The flowchart of a control method for a display screen provided by an embodiment of the present disclosure. Refer to Figure 1 At least one control method for a display screen provided by an embodiment of the present disclosure includes the following steps S1 to S3.

[0063] S1: Determine the target attribute satisfied by the target application, where the target attribute corresponds to a preset aspect ratio;

[0064] S2: Obtain the preset aspect ratio;

[0065] S3: Adjust the aspect ratio of the display screen according to the preset aspect ratio so that the value of the aspect ratio of the display screen reaches the target aspect ratio, where the aspect ratio of the display screen is the ratio of the horizontal dimension to the vertical dimension of the display area of the display screen, and the vertical and horizontal intersect.

[0066] For example, this control method for the display screen can be used for an in-vehicle display screen. The following specific embodiments take the application scenario where the display screen is an in-vehicle display screen as an example to introduce the control method and control system, etc. provided by the present disclosure. However, it is not limited to an in-vehicle display screen and can be any type of display device, such as the display screen of a mobile phone, a tablet computer, or any other device with a display function.

[0067] In the control method for the display screen provided by an embodiment of the present disclosure, the aspect ratio of the display screen is directly adjusted according to the preset aspect ratio corresponding to the target attribute satisfied by the target application to be displayed on the display screen. The preset aspect ratio is existing and already present. Therefore, the method for adjusting the aspect ratio of the display screen is simple and efficient. In non-essential cases, it may not be necessary to obtain the aspect ratio of the content (which can be understood as the interface of the target application itself) of the target application to be launched by the user and adjust the aspect ratio of the display screen accordingly. Thus, it can quickly match the aspect ratio of the display screen with the aspect ratio of the interface of the application software (i.e., the target application) that the user wants to display using the display screen, reduce the gap between the aspect ratio of the display screen and the aspect ratio of the interface of the target application, and even make the two equal, improving the user experience.

[0068] For example, the horizontal direction refers to the direction that is basically parallel to the ground, and the vertical intersects with the horizontal. For example, if the display screen is a rectangular screen, the vertical is perpendicular to the horizontal. In the case where the display screen is an in-vehicle display screen, the horizontal direction refers to the direction that is basically parallel to the bottom surface inside the vehicle cab or the real-time road surface during driving. Of course, the horizontal and vertical are not limited to the above situations, and only the relatively common cases are given here as exemplary explanations.

[0069] The target application can be various application software, applets, etc. that can be loaded on a display device, and is an application that the user wants to start using a display device including a display screen to display the interface of the target application on the display screen. Exemplarily, the target application can include multimedia applications (video, audio playback applications), navigation applications (Gaode Map, Baidu Map, etc.), shopping applications (Taobao, JD.com, etc.), social applications (WeChat, QQ, etc.), and so on. Of course, the target application is not limited to the types listed above, and the specific type of the target application is not limited in the embodiments of the present disclosure.

[0070] It should be noted that the target attributes satisfied by the target application can include being adapted to the current display screen, the target application being adapted to the device attributes of the device, etc., which will be specifically introduced below.

[0071] Adjusting the aspect ratio of the display screen as described herein refers to adjusting the horizontal or vertical dimension of the actual display screen used by the user to adjust the aspect ratio of the display screen participating in the display, so as to adjust the number of pixels in the horizontal or vertical direction participating in the display. That is, adjusting the aspect ratio of the display screen object, rather than simply keeping the horizontal or vertical dimension of the display screen object unchanged and only adjusting the proportion of the display picture in the display screen in the entire display area of the display screen.

[0072] Figure 2 It is a schematic diagram of the matching situation between the display screen and the target application before and after adjusting the aspect ratio of the display screen in an embodiment of the present disclosure. Figure 2 In (a) and (b) thereof, the solid line frame represents the edge of the display area of the display screen, and the dashed line frame represents the edge of the interface of the target application. Figure 2 (a) thereof shows a situation where the aspect ratios of the display screen and the target application do not match before adjusting the aspect ratio of the display screen. Figure 2 (a) thereof shows a situation where the aspect ratios of the display screen and the target application match after adjusting the aspect ratio of the display screen by using the display screen control method provided in the embodiments of the present disclosure.

[0073] For example, at least one of the horizontal dimension and the vertical dimension of the display screen is adjustable so that the aspect ratio of the picture displayed on the display screen is adjustable, that is, changing at least one of the horizontal dimension and the vertical dimension of the display screen to change the aspect ratio of the display area of the display screen. Taking a vehicle-mounted display device as an example, for example, the vehicle-mounted display device further includes a display screen driving device, and the display screen driving device is configured to be able to drive the display screen to expand and contract in at least one of the horizontal and vertical directions to adjust the horizontal dimension and / or the vertical dimension of the display screen, so as to realize the change of the aspect ratio of the display screen. The specific mechanical structure design of the display screen driving device and the like for changing the aspect ratio of the display screen can refer to the conventional design in the art, and the embodiments of the present disclosure do not limit this.

[0074] When the in-vehicle display screen can be stretched in both the horizontal and vertical directions, the following specific methods can be adopted:

[0075] (1) Adjust the vertical dimension first, and then adjust the horizontal dimension, that is, the stretching range in the vertical direction is exhausted first. When the requirements cannot be met, then adjust the horizontal dimension;

[0076] (2) Adjust the horizontal dimension first, and then adjust the vertical dimension;

[0077] (3) Adjust the vertical dimension and the horizontal dimension simultaneously. A recommended value for the vertical stretching range (80% stretching range) can be set, and a recommended value for the horizontal dimension (30% stretching range) can be set. The recommended value refers to the ratio of directly scaling the dimension in that direction to the maximum dimension in that direction. The specific recommended value can be selected according to the hardware. If the horizontal interference is small (including interference to the activities of the co-pilot, interference to the driver's line of sight, etc.), the horizontal recommended value can be increased. If the vertical interference is small, the vertical recommended value can be increased.

[0078] For example, the control method of the display screen provided by the embodiments of the present disclosure further includes: starting the target application after completing the adjustment of the aspect ratio of the display screen, so that after the user starts the target application, the user can view the interface of the target application that matches the aspect ratio of the display screen, and obtain a better user experience.

[0079] For example, the control method of the display screen provided by at least one embodiment of the present disclosure further includes: after the user selects the target application, the system controls the adjustment of the aspect ratio of the display screen so that the aspect ratio of the display screen matches the aspect ratio of the application, and a better user experience is obtained.

[0080] For example, the control method of the display screen provided by at least one embodiment of the present disclosure further includes: after the user selects the target application, the system controls the adjustment of the aspect ratio of the display screen to a first preset aspect ratio so that the aspect ratio of the display screen matches the aspect ratio of the application. After the user further selects the content of the target application, the aspect ratio of the display screen is further adjusted to a second preset aspect ratio according to the content of the target application so that the aspect ratio of the display screen matches the aspect ratio of the content of the target application, and a better user experience is obtained.

[0081] For example, before performing the step of adjusting the aspect ratio of the display screen, the control method of the display screen provided by the embodiments of the present disclosure further includes: turning on the display device including the display screen, for example, automatically turning on the in-vehicle display device after the vehicle starts; and receiving the trigger information of the target application, for example, the user selects and triggers the target application by touching the in-vehicle display.

[0082] For example, adjusting the aspect ratio of the display screen according to a preset aspect ratio includes: adjusting the aspect ratio of the display screen to the preset aspect ratio, and the target aspect ratio is equal to the preset aspect ratio. Thus, it is possible to more directly and quickly make the aspect ratio of the display screen match the preset and existing target aspect ratio, quickly achieve a better match between the aspect ratio of the display screen and the aspect ratio of the interface of the application to be launched by the user, and better improve the user experience.

[0083] Of course, in other embodiments, it may also be to adjust the aspect ratio of the display screen to a value calculated based on the preset aspect ratio. The aspect ratio of the display screen and the preset aspect ratio are not necessarily equal. For example, the target aspect ratio may also be greater than or less than the preset aspect ratio, and the calculation method can be set according to needs.

[0084] Figure 3A The flowchart of a method for determining the target attributes satisfied by the target application and obtaining the preset aspect ratio provided by an embodiment of the present disclosure. Refer to Figure 3A , determining the target attributes satisfied by the target application and obtaining the preset aspect ratio includes steps S23 to S24.

[0085] S23: Determine the device attributes adapted to the target application, where the above target attributes include the device attributes adapted to the target application;

[0086] S24: Obtain the aspect ratio corresponding to the device attributes adapted to the target application as the preset aspect ratio.

[0087] In this way, it is possible to adjust the aspect ratio of the display screen according to the existing aspect ratio corresponding to the device attributes adapted to the target application. For example, directly adjust the aspect ratio of the display screen to the existing aspect ratio adapted to the target application, so as to quickly and at least to a certain extent reduce the gap between the aspect ratio of the interface of the target application and the aspect ratio of the display screen, improve the matching degree between the two, and thus improve the user experience of the in-vehicle display screen.

[0088] The device attributes may be the inherent attributes of the device. For example, they may include device type, device model, etc., as introduced below.

[0089] Figure 3B The flowchart of another method for determining the target attributes satisfied by the target application and obtaining the preset aspect ratio provided by an embodiment of the present disclosure. Refer to Figure 3B , for example, in the control method of the display screen provided by at least one embodiment, determining the target attributes satisfied by the target application and obtaining the preset aspect ratio includes steps S21 to S22.

[0090] S21: Determine whether the target application belongs to an application adapted to the display screen. If so, execute step S22.

[0091] S22: Use the default aspect ratio that matches the target application on the display screen as the preset aspect ratio, where the target attributes satisfied by the target application include being adapted to the current display screen.

[0092] In the case of determining that the target application is an application adapted to the display screen and performing step S22, start the application with the default aspect ratio as the preset aspect ratio. When using the default aspect ratio as the final target aspect ratio of the display screen, adjusting the aspect ratio of the display screen according to the preset aspect ratio so that the value of the aspect ratio of the display screen reaches the target aspect ratio results in: There is no need to adjust the aspect ratio of the display screen, and directly start the target application based on the default aspect ratio of the display screen.

[0093] For example, in at least one embodiment, refer to Figure 3B , if the target application does not belong to the application adapted to the display screen, then perform the above steps S23 - S24.

[0094] In this way, it is also possible to quickly and at least to a certain extent reduce the gap between the aspect ratio of the interface of the target application and the aspect ratio of the display screen, improve the matching degree between the two, and thus enhance the user experience of using the in - vehicle display screen.

[0095] Figure 4 It is a flowchart of a method for obtaining a preset aspect ratio provided by an embodiment of the present disclosure. For example, the above - mentioned device attribute is the device type, and the control method of the display screen includes Figure 4 the steps S101 - S102 shown.

[0096] S101: Determine the device type to which the target application is adapted;

[0097] S102: Obtain the aspect ratio to which the target application is adapted to this device type as the preset aspect ratio.

[0098] The device type can include various types, such as mobile phones, tablets, laptop computers, desktop computers, etc. The target application often already has an adapted device type. Using the method shown in steps S101 - S102 can quickly adjust the aspect ratio of the current display screen according to the existing aspect ratio adapted to this device type, quickly reduce the gap between the aspect ratio of the interface of the target application and the aspect ratio of the display screen, improve the matching degree between the two, and thus enhance the user experience of using the in - vehicle display screen.

[0099] Specifically, for example, if the target application has a first preset aspect ratio that has been adapted to a first type of device, the aspect ratio of the display screen is adjusted to the first preset aspect ratio, where the first preset aspect ratio is less than or equal to 1, that is, the aspect ratio of the display screen of the first type of device that has been adapted to the target application is less than or equal to 1. For example, the first type of device includes devices with communication functions such as mobile phones. In this way, the target aspect ratio of the current display screen can be quickly locked, and the aspect ratio of the current display screen can be quickly adjusted to match the target application according to the first preset aspect ratio that has been matched with the target application on the first type of device. For example, the first aspect ratio is 1:1 to 1:2.5. Of course, this is only exemplary, and the numerical range of the first aspect ratio is not limited to this, and the first type of device is not limited to the above-listed types either.

[0100] For example, mobile phones include foldable mobile phones and non-foldable mobile phones. The first preset aspect ratio of a mobile phone that has been adapted to the target application can be the aspect ratio of the mobile phone screen after folding or the aspect ratio of the mobile phone screen before folding. As long as it has been matched, the above method can be used to adjust the aspect ratio of the current display screen, such as the in-vehicle display screen.

[0101] Again, for example, if the target application has been adapted to a second type of device, the aspect ratio of the display screen is adjusted to a second preset aspect ratio, where the aspect ratio of the display screen of the second type of device that has been adapted to the target application is greater than 1, that is, the aspect ratio of the display screen of the second type of device that has been adapted to the target application is greater than 1. For example, the second type of device includes tablets, laptop computers, desktop computers, etc. In this way, the target aspect ratio of the current display screen can be quickly locked, and the aspect ratio of the current display screen can be quickly adjusted to match the target application according to the second preset aspect ratio that has been matched with the target application on the second type of device. For example, the second aspect ratio is 3:2 to 2:1. Of course, this is only exemplary, and the numerical range of the second aspect ratio is not limited to this, and the second type of device is not limited to the above-listed types either.

[0102] Figure 5A It is a flowchart of another method for obtaining a preset aspect ratio provided by an embodiment of the present disclosure. For example, the above device attributes include the device model. The control method of the display screen provided by at least one embodiment of the present disclosure includes Figure 5A the steps S201 to S202 shown.

[0103] S201: Determine the device model to which the target application has been adapted;

[0104] S202: Obtain the aspect ratio to which the target application has been adapted to this type of device as the preset aspect ratio.

[0105] By using this method, the aspect ratio of the device model that has been matched with the target application can be obtained as the preset aspect ratio according to the specific device model, so as to more accurately adjust the aspect ratio of the display screen and improve the matching effect between the current display screen and the aspect ratio of the target application.

[0106] Figure 5B It is a flowchart of another method for obtaining a preset aspect ratio provided by an embodiment of the present disclosure. For example, in another embodiment, on the basis that the above device attributes include the device type, the above device attributes further include the device model. In the control method of the display screen provided by at least one embodiment of the present disclosure, in addition to judging the device type, the device model also needs to be judged. Therefore, the control method of the display screen provided by at least one embodiment of the present disclosure includes Figure 5B The steps S201a to S202a shown in

[0107] S201a: Judge the device type and device model that the target application has been adapted to;

[0108] S202a: Obtain the aspect ratio of the device of this model that the target application has been adapted to as the preset aspect ratio.

[0109] In this way, on the basis of judging the device type, the device model is also judged. When the device types are the same, for example, a mobile phone or a tablet, there may also be certain differences between the aspect ratios of different models of devices that have been matched with the target application. By using this method, the aspect ratio of the device of this type that has been matched with the target application can be obtained as the preset aspect ratio according to the device type, so as to more accurately adjust the aspect ratio of the display screen and improve the matching effect between the current display screen and the aspect ratio of the target application.

[0110] Exemplarily, for example, judge which specific model of mobile device the target application belongs to. For example, if the target application is adapted to a mobile device of the Huawei model, then adjust the aspect ratio of the current display screen, such as the in-vehicle display screen, to 1:2.1; further, if the target application is specifically adapted to the Huawei Mate 60, then adjust the aspect ratio of the current display screen to 1:2.2.

[0111] Exemplarily, for example, judge which specific model of tablet the target application belongs to. For example, if the target application is adapted to a MatePad device of the Huawei model, then adjust the aspect ratio of the current display screen, such as the in-vehicle display screen, to 1.5:1.

[0112] Figure 6 It is a flowchart of yet another method for obtaining a preset aspect ratio provided by an embodiment of the present disclosure. The control method of the display screen provided by at least one embodiment of the present disclosure includes Figure 6 The steps S301 to S302 shown in

[0113] S301: Determine the type of the target application, where the target attribute includes the type of the target application;

[0114] S302: Obtain the aspect ratio corresponding to the type of the target application as the preset aspect ratio.

[0115] Generally, different types of applications already have the aspect ratios of the displays adapted to them. Through the method shown in steps S301 - S302, the aspect ratio of the display matching the target application can be quickly locked according to the type of the target application, so as to simply and efficiently adjust the aspect ratio of the display according to the aspect ratio matching the type of the target application.

[0116] For example, the type of the target application includes at least one of multimedia applications, short video applications, navigation applications, social applications, and shopping applications. Of course, the type of the target application is not limited to the above - listed types.

[0117] For example, the method for controlling the display screen includes: obtaining the maximum aspect ratio and the minimum aspect ratio of the display screen. Among them, if the type of the target application is a multimedia application (such as Youku, Tencent Video, etc.), the preset aspect ratio is the maximum aspect ratio of the current display screen. For example, the aspect ratio of the current display screen can be directly adjusted to the maximum aspect ratio of the display screen. That is, when the type of the application is suitable for an aspect ratio that is significantly larger, such as greater than 1, the aspect ratio of the current display screen can be directly adjusted to the maximum aspect ratio of the display screen. For example, it can be adjusted to the maximum aspect ratio of 21:9. Of course, the maximum aspect ratio is not limited to this value. If the type of the target application is a short - video application (such as Douyin, Kuaishou, etc.), the preset aspect ratio is the minimum aspect ratio of the current display screen. For example, the aspect ratio of the current display screen can be directly adjusted to the minimum aspect ratio of the display screen. That is, when the type of the application is suitable for an aspect ratio that is significantly smaller, such as less than 1, the aspect ratio of the current display screen can be directly adjusted to the minimum aspect ratio of the display screen. If the type of the target application is a navigation application (such as Gaode Map, Baidu Map), the value of the preset aspect ratio is between the minimum aspect ratio and the maximum aspect ratio of the current display screen. That is, when the type of the application is suitable for a moderate aspect ratio, the aspect ratio value of the adjusted current display screen can be made to be between the minimum aspect ratio and the maximum aspect ratio of the current display screen. Through this method, the aspect ratio of the display close to matching the target application can be quickly locked according to the type of the target application. By directly adjusting the aspect ratio of the current display screen to the maximum or minimum aspect ratio of the display screen, the gap between the aspect ratio of the interface of the target application and the aspect ratio of the current display screen can be simply and efficiently reduced to a certain extent, improving the matching degree between the two.

[0118] For example, if the type of the target application is a multimedia application, the control method of the display screen includes: determining whether the display screen is longitudinally scalable (for the description of the longitudinal direction, please refer to the foregoing text); if so, adjusting the aspect ratio of the display screen to a third preset aspect ratio corresponding to the multimedia application, for example, the third preset aspect ratio is greater than 1; if not, obtaining the maximum aspect ratio of the display screen and adjusting the aspect ratio of the display screen to the maximum aspect ratio of the display screen. Generally, the aspect ratio of media applications is greater than 1, such as 16:9, and for example, the third preset aspect ratio is 16:9, although it is not limited to 16:9. Thus, it is possible to make the aspect ratio of the display screen match the aspect ratio of media applications as much as possible.

[0119] For example, if the type of the target application is a short video application, the control method of the display screen provided by at least one embodiment of the present disclosure includes: determining whether the current display screen is longitudinally scalable; if so, adjusting the aspect ratio of the current display screen to a fourth preset aspect ratio corresponding to the short video application, and the fourth preset aspect ratio is less than 1, such as 1:2.1, 1:2.2, 1:2.3, etc.; if not, obtaining the minimum aspect ratio of the display screen and adjusting the aspect ratio of the display screen to the minimum aspect ratio of the display screen. Thus, when the display screen can be longitudinally scaled, the adjustment range of the longitudinal dimension can be relatively large to achieve a smaller aspect ratio and it is convenient to reduce the aspect ratio. Therefore, in this case, it is relatively easy to adjust the aspect ratio of the current display screen to the fourth preset aspect ratio (less than 1) corresponding to the short video application, so that the current display screen and the aspect ratio of the target application achieve a better matching effect, greatly improving the user experience. When the display screen cannot be longitudinally scaled, it is difficult to make the current display screen have a smaller aspect ratio. At this time, directly adjusting the aspect ratio of the display screen to the minimum aspect ratio of the display screen is simple and direct, omitting the consideration of other factors, and can quickly adjust the aspect ratio of the current display screen to reduce the difference between its aspect ratio and the aspect ratio of the interface of the target application to a certain extent.

[0120] For example, in another embodiment, if the type of the target application is a multimedia application, the control method includes: determining the playback history of the multimedia application; and obtaining the aspect ratio of the multimedia content in the playback history as the preset aspect ratio. For example, taking the aspect ratio of the multimedia content with the most occurrences or frequencies in the playback history as the preset aspect ratio, and for example, directly adjusting the aspect ratio of the current display screen to this preset aspect ratio to simply and efficiently reduce the difference between its aspect ratio and the aspect ratio of the interface of the target application. For example, in this embodiment, the control method further includes: the display device including the display screen obtains content from the server of the media application.

[0121] For example, in another embodiment, the system can obtain the aspect ratio of the display screen of the display device that has the target application enabled under the user account. Here, the target application can be any of the above-mentioned applications. According to the aspect ratio of the most recently applicable device under the user account, for example, the aspect ratio of the mobile device used within a preset period of time recently or the most frequently used mobile device aspect ratio can be used as the aspect ratio of the most recently applicable device, and adjust the aspect ratio of the in-vehicle display device; for example, if the aspect ratio of the mobile device used within a preset period of time recently or the most frequently used mobile device aspect ratio is 1:2.1, then determine whether the minimum aspect ratio of the display device is less than or equal to 1:2.1. If it is less than or equal, set the aspect ratio of the in-vehicle display device to 1:2.1. Of course, this data is only exemplary and is not limited to 1:2.1.

[0122] For example, the control method for the display screen provided by at least one embodiment of the present disclosure includes: if the type of the target application is a multimedia application, control the display screen to expand and contract at a first rate to adjust the aspect ratio of the display screen; if the application type is a short video application, control the display screen to expand and contract at a second rate different from the first rate to adjust the aspect ratio of the display screen. Since compared with the multimedia application, the difference between the horizontal size and the vertical size of the display screen adapted to the short video application is different, and the difference between the horizontal size and the vertical size of the display screen is different, therefore, using different expansion and contraction rates is beneficial to adapting to different adjustment amplitudes to improve the adjustment efficiency of the aspect ratio of the display screen.

[0123] For example, the second rate is greater than the first rate. Since the difference between the horizontal size and the vertical size of the display screen adapted to the short video application often exceeds the difference between the horizontal size and the vertical size of the usually default in-vehicle display screen by a large margin, therefore, increasing the expansion and contraction rate of the display screen for the short video application is beneficial to quickly achieving the size of the display screen that matches the short video application and improving the adjustment efficiency of the aspect ratio of the display screen.

[0124] For example, the expansion and contraction direction of the display screen is vertical, and the second rate is greater than the first rate. Since the short video application requires a larger size in the vertical direction, a larger second rate is beneficial to improving the adjustment speed of the aspect ratio of the display screen adapted to the short video application.

[0125] For example, the screen expansion and contraction direction of the display screen is horizontal, and the second rate is less than the first rate. Similarly, since the multimedia application requires a larger size in the horizontal direction, a larger first rate is beneficial to improving the adjustment speed of the aspect ratio of the display screen adapted to the multimedia application.

[0126] Figure 7 is a flowchart of yet another method for obtaining a preset aspect ratio provided by an embodiment of the present disclosure. The control method provided by at least one embodiment of the present disclosure includes Figure 7 the steps S401 to S403 shown.

[0127] S401: Obtain the aspect ratio adjustment range of the display screen. Among them, the range of the aspect ratio of the display screen is a to b (a < b), where a is the minimum value of the aspect ratio of the display screen, and b is the maximum value of the aspect ratio of the display screen;

[0128] S402: Obtain the aspect ratio adapted by the target application, and compare this ratio with the aspect ratio range of the display screen;

[0129] S403: If the aspect ratio adapted by the target application is greater than b, then use the maximum value b of the aspect ratio of the display screen as the preset aspect ratio; if the aspect ratio adapted by the target application is less than a, then use a as the preset aspect ratio, and adjust the aspect ratio of the display screen to a; if the aspect ratio adapted by the target application is greater than a and less than b, then use the aspect ratio adapted by the target application as the preset aspect ratio.

[0130] Thus, it is possible to quickly determine a suitable preset aspect ratio according to the relationship between the aspect ratio adapted by the target application and the aspect ratio adjustment range of the display screen, so as to make the aspect ratio of the current display screen tend to match that of the target application according to different situations.

[0131] Further, for example, a is less than 1 and b is greater than 1. For example, a = 1:3 and b = 16:9. Of course, the values of a and b are not limited to these values.

[0132] Figure 8 It is a flowchart of another method for controlling the aspect ratio of a display screen provided by an embodiment of the present disclosure. Another embodiment of the present disclosure also provides a method for controlling a display screen, and the method for controlling the display screen includes Figure 8 the steps S501 shown.

[0133] S501: After completing the adjustment of the aspect ratio of the display screen according to the preset aspect ratio, obtain the aspect ratio of the display screen of the target application as the content aspect ratio, and further adjust the aspect ratio of the display screen to the content aspect ratio.

[0134] Figure 8The method shown is based on the control method of any of the above display screens. A subsequent adjustment step is superimposed, that is, step-by-step adjustment. First, quickly lock the existing preset aspect ratio, adjust the aspect ratio of the display screen according to the preset aspect ratio, and then, fine-tune the aspect ratio of the display screen according to the specific content of the target application, and further adjust the aspect ratio of the display screen to the content aspect ratio, so that the aspect ratio of the display screen matches the aspect ratio of the interface of the target application more. At the same time, compared with only fine-tuning the aspect ratio of the display screen according to the specific content of the target application, the control method provided in this embodiment not only takes into account the matching degree between the specific content of the target application and the aspect ratio of the display screen, but also can take into account the adjustment efficiency of the aspect ratio of the display screen, which can reduce the waiting time for the display screen to expand and contract when the user views the content of the target application, and improve the user experience. For example, in this embodiment, the control method further includes: a display device including the display screen obtains content from the server of the media application.

[0135] Exemplarily, adjust the aspect ratio of the display screen of the display device to the maximum aspect ratio of 21:9. When the user selects a piece of content with an aspect ratio of 16:9 in the multimedia application, adjust the aspect ratio of the display screen to 16:9 to further improve the matching degree between the target application and the aspect ratio of the display screen through step-by-step adjustment.

[0136] Figure 9 It is a flowchart of another control method for the aspect ratio of a display screen provided by an embodiment of the present disclosure. The control method provided by at least one embodiment of the present disclosure includes Figure 9 the steps S601 to S603 shown.

[0137] S601: Obtain the maximum aspect ratio and the minimum aspect ratio of the display screen;

[0138] S602: Compare the content aspect ratio with the maximum aspect ratio of the display screen and the minimum aspect ratio of the display screen respectively;

[0139] S603: If the content aspect ratio is greater than or equal to the maximum aspect ratio of the display screen, adjust the aspect ratio of the screen to the maximum aspect ratio;

[0140] If the content aspect ratio is less than or equal to the minimum aspect ratio of the display screen, adjust the aspect ratio of the screen to the minimum aspect ratio;

[0141] If the content aspect ratio is less than the maximum aspect ratio of the display screen and greater than the minimum aspect ratio of the display screen, adjust the aspect ratio of the display screen to the content aspect ratio.

[0142] Thus, it is possible to achieve a balance between the aspect ratio of the content of the target application and the aspect ratio range of the display screen, and reasonably adjust the aspect ratio of the display screen to adapt to the target application.

[0143] It should be noted that the vertical adjustability of the display screen is just one case. In fact, as long as the adjustment is made according to the method provided in the embodiments of the present disclosure, it is not limited to only adjusting the aspect ratio of the display screen in the vertical direction. In the control methods of the display screens provided in all embodiments of the present disclosure, the vertical dimension of the display screen can be adjusted in the vertical direction, or the horizontal dimension of the display screen can be adjusted in the horizontal direction, or both the vertical dimension of the display screen can be adjusted in the vertical direction and the horizontal dimension of the display screen can be adjusted in the horizontal direction.

[0144] For example, a plurality of telescopic length gradients are provided on at least one of the horizontal and vertical directions, and the display screen is controlled to adjust the horizontal dimension and / or the vertical dimension of the display screen according to the telescopic length gradient on at least one of the horizontal and vertical directions, so as to adjust the aspect ratio of the display screen. Specifically, for example, the plurality of gradients can be equal, and the length of each gradient is a. The length of the display area of the display screen in the horizontal and / or vertical directions can be increased or decreased one by one for each gradient, that is, for each adjustment of a gradient, the value by which the length of the display area of the display screen increases or decreases correspondingly is a, which is convenient for the user to perform the operation of adjusting the aspect ratio of the display screen conveniently and quickly. Of course, the plurality of gradients can also be unequal. Thus, step-by-step adjustment can be realized, the adjustment difficulty can be reduced, the aspect ratio of the display screen can be controlled as needed, and the adjustment can be made more flexible and controllable.

[0145] Figure 10 It is a schematic diagram of another control method of a display screen provided by an embodiment of the present disclosure. For example, a plurality of sub-display screens are spliced together to form a display screen, and the plurality of sub-display screens are respectively used to display corresponding target applications; for example, referring to Figure 10 , the plurality of sub-display screens include a first sub-display screen 1 and a second sub-display screen 2, Figure 10 The dotted line in [[ ]] is the dividing line between the first sub-display screen 1 and the second sub-display screen 2. For example, the first sub-display screen 1 and the second sub-display screen 2 are respectively the screens close to the driver's seat position and the co-driver's seat position.

[0146] Figure 11 It is a flowchart of another method for controlling the aspect ratio of a display screen provided by an embodiment of the present disclosure. For example, referring to Figure 10 and Figure 11 , the control method of the display screen includes Figure 11 the steps S701 to S702 shown in [[ ]].

[0147] S701: Determine whether the target applications displayed by the plurality of sub-display screens are associated with each other;

[0148] S702: If the target applications respectively displayed by the plurality of sub-display screens are associated with each other, synchronously adjust the horizontal dimension and / or the vertical dimension of the plurality of sub-display screens respectively, so that the aspect ratio of the display screen formed by splicing the plurality of sub-display screens with each other is the target aspect ratio;

[0149] If the target applications of multiple sub-displays or the content of the target applications respectively displayed are independent of each other, each sub-display is used as an independent display screen, and the aspect ratio of each sub-display is adjusted respectively according to the preset aspect ratio of the application used for display of each sub-display, so that the value of the aspect ratio of the sub-display reaches its respective target aspect ratio.

[0150] Thereby, it is possible to realize the combined display of the content of the same target application on the screen formed by splicing multiple sub-displays, that is, the content of the target applications displayed on multiple sub-displays is associated with each other. It can be understood that the target applications respectively displayed on multiple sub-displays are associated with each other means that the content displayed on multiple sub-displays is spliced into the same complete image, that is, a combined image. In this case, the horizontal size and / or vertical size of multiple sub-displays can be adjusted simultaneously respectively, so that the aspect ratio of the display screen formed by splicing multiple sub-displays is the target aspect ratio, and the aspect ratio of the spliced screen is matched with the aspect ratio of the combined image.

[0151] For example, when the target applications are associated with each other and the horizontal size and / or vertical size of multiple sub-displays are adjusted synchronously respectively, so that the aspect ratio of the display screen formed by splicing multiple sub-displays is the target aspect ratio, the displayed content is associated with each other.

[0152] Exemplarily, such as Figure 10 , for example, when the vehicle is in the rest mode (such as the seat becomes a large bed), the first sub-display 1 (aspect ratio 16:9) and the second sub-display 2 (aspect ratio 16:9) are combined into an overall screen (aspect ratio 32:18), and the first sub-display 1 and the second sub-display 2 can be stretched and shrunk simultaneously. For example, this overall screen can display pictures, and the pictures of the first sub-display 1 and the second sub-display 2 are spliced with each other to form a complete picture content, and the user can enjoy the large-screen experience.

[0153] Exemplarily, such as Figure 12 , the first sub-display 1 (for example, aspect ratio 16:9) and the second sub-display 2 (for example, aspect ratio 16:9) are combined into an overall screen (for example, aspect ratio 32:18), and the first sub-display 1 and the second sub-display 2 can be stretched and shrunk simultaneously. For example, this overall screen can also be used to play videos, and the videos of the first sub-display 1 and the second sub-display 2 are spliced with each other to form a complete video content.

[0154] For example, the horizontal and / or vertical dimensions of multiple sub-displays are adjusted synchronously to make the vertical dimension of the entire display consistent along the horizontal direction, while taking into account the aspect ratio of the entire display formed by splicing multiple sub-displays to match the aspect ratio of the combined image. When using a splicing screen formed by multiple sub-displays to display related content, whether the vertical dimensions at various positions in the horizontal direction of the display are consistent has a great impact on the viewing experience. Adopting the above method can ensure the user's viewing experience.

[0155] At least one embodiment of the present disclosure further provides a display control system. Figure 13 Schematic block diagram of a display control system provided by at least one embodiment of the present disclosure. Refer to Figure 13 , the display control system 100 includes: a target attribute judgment module 101, an aspect ratio acquisition module 102, and an aspect ratio adjustment control module 103. These modules are interconnected through a bus system and / or other forms of connection mechanisms (not shown). For example, these modules can be implemented through hardware (such as circuits), software modules, or any combination of the two. The same applies to the following embodiments and will not be repeated. For example, these units can be implemented through a central processing unit (CPU), a graphics processing unit (GPU), a tensor processing unit (TPU), a field programmable gate array (FPGA), or other forms of processing units with data processing capabilities and / or instruction execution capabilities, as well as corresponding computer instructions.

[0156] Refer to Figure 13 , the display control system 100 further includes a display driving device 104. The target attribute judgment module 101 is configured to judge the target attributes satisfied by the target application, and the target attributes correspond to a preset aspect ratio; the aspect ratio acquisition module 102 is configured to acquire the preset aspect ratio; the display driving device 104 is signal-connected to the aspect ratio adjustment control module 103, and the aspect ratio adjustment control module 103 is configured to control the display driving device 104 to drive the display to expand or contract in at least one of the horizontal and vertical directions according to the preset aspect ratio, so as to adjust the horizontal dimension and / or vertical dimension of the display, thereby adjusting the aspect ratio of the display so that the value of the aspect ratio of the display reaches the target aspect ratio; the aspect ratio of the display is the ratio of the horizontal dimension to the vertical dimension of the display, and the vertical is perpendicular to the horizontal.

[0157] For example, the display control system is a vehicle-mounted display control system, and the display is a vehicle-mounted display.

[0158] The display control system provided by the embodiments of the present disclosure can achieve the same working process and technical effects as the embodiments of the display control method, which will not be repeated here. Please refer to the previous description.

[0159] Figure 13The modules and structures of the display control system 100 shown are exemplary and not restrictive. According to requirements, the display control system 100 may also have other components and structures.

[0160] For example, the target attribute judgment module 101, the aspect ratio acquisition module 102, and the aspect ratio adjustment control module 103 may include codes and programs stored in a memory; a processor may execute the codes and programs to implement some or all of the functions of the target attribute judgment module 101, the aspect ratio acquisition module 102, and the aspect ratio adjustment control module 103 as described above. For example, the target attribute judgment module 101, the aspect ratio acquisition module 102, and the aspect ratio adjustment control module 103 may be dedicated hardware devices for implementing some or all of the functions of the target attribute judgment module 101, the aspect ratio acquisition module 102, and the aspect ratio adjustment control module 103 as described above.
