[0068] like Figure 1 As shown, this application provides a screen display method. The executing entity of this application embodiment can be a terminal device, which can be a display terminal such as a television, or a computing device such as a desktop computer, laptop, handheld computer, or cloud server connected to a display terminal such as a television. As an example and not a limitation, the screen display method provided in this application embodiment will be described in detail below using a display terminal such as a television for screen display as the executing entity. The screen display method may include:

[0069] S101. When the screen to be displayed is obtained, the driving device corresponding to the display terminal is activated. The driving device is connected to the display terminal so as to drive the display terminal to move and obtain the first adjustment rate and the first adjustment direction of the display terminal. The screen to be displayed is the display screen formed by the display terminal.

[0070] It is understood that the screen to be displayed is a display screen formed by media information output to the display terminal. For example, the media information can be images or videos projected from a mobile terminal such as a mobile phone, tablet, or wearable device onto a display terminal such as a television. Specifically, a connection can be established between the mobile terminal and the display terminal in advance. When the mobile terminal detects that the user needs to project images or videos viewed on the mobile terminal onto the display terminal, it can send a projection request to the display terminal. For example, the mobile terminal can send a projection request to the display terminal when it detects a user's shake operation or when the user clicks a projection button on the mobile terminal screen. After receiving the projection request, the display terminal can determine whether to accept the projection request based on the specific situation. If it determines to accept the projection request, it can send a receive command to the mobile terminal, and the mobile terminal can then send images or videos to the display terminal according to the receive command. For example, the mobile terminal can record images or videos displayed on the mobile terminal screen at a certain frame rate, and simultaneously record the corresponding audio. The recorded images or videos and the recorded audio are then encoded separately and streamed to the display terminal in real time.

[0071] Here, when the display terminal receives the encoded content image sent by the mobile terminal, it can first decode it to obtain the image to be displayed (i.e., image or video content) sent by the mobile terminal. Then, it can determine whether to adjust the display terminal based on the image to be displayed. For example, it can determine whether to adjust the display terminal based on the display mode corresponding to the image to be displayed. If it is determined to adjust the display terminal, it can be adjusted, and the first adjustment rate and first adjustment direction during the adjustment process can be obtained. For example, during the adjustment process, the first adjustment rate and first adjustment direction of the display terminal in the horizontal or vertical direction can be measured in real time by a measuring device such as a gyroscope installed in the display terminal. That is, the first adjustment rate and first adjustment direction can be the adjustment rate and direction of the display terminal relative to the horizontal direction, or the adjustment rate and direction of the display terminal relative to the vertical direction.

[0072] Please see Figure 2a , Figure 2a A schematic diagram of the driving device provided in an embodiment of this application is shown. Figure 2aThe driving device 20 can be connected to the display terminal 30 or to a connecting plate 40 for mounting the display terminal 30. The driving device 20 may include a reducer 21 and a motor 22. The reducer 21 is located between the display terminal 30 and the motor 22. The shaft of the reducer 21 extends horizontally forward and is connected to the display terminal 30 or the connecting plate 40, thereby connecting the display terminal 30 or the connecting plate 40 to the motor 22. The reducer 21 and the motor 22 start synchronously, driving the display terminal 30 to move or driving the connecting plate 40 to move, thereby moving the display terminal 30.

[0073] In this embodiment, adjusting the display terminal refers to changing the display terminal from landscape mode to portrait mode, or vice versa. The first adjustment direction refers to adjusting the display terminal clockwise or counter-clockwise. The first adjustment rate can be the angle adjusted per second.

[0074] For example, adjusting the display terminal in this embodiment of the application can refer to rotating the display terminal. The adjustment rate can be the rotation rate, and the adjustment direction can be the rotation direction. That is, the first adjustment rate can be a first rotation rate at which the display terminal is rotated, and the first adjustment direction can be a first rotation direction at which the display terminal is rotated. Similarly, the second adjustment rate described later can be a second rotation rate at which the display terminal is rotated, and the second adjustment direction can be a second rotation direction at which the display terminal is rotated.

[0075] In one possible implementation, the display terminal may first obtain the initial screen width and initial screen height of the image to be displayed, as well as the screen width and screen height of the display terminal; then, it may determine a first display mode corresponding to the image to be displayed based on the initial screen width and initial screen height, and determine a second display mode corresponding to the display terminal based on the screen width and screen height; finally, it may determine whether to adjust the display terminal based on the first display mode and the second display mode; if it is determined that the display terminal should be adjusted based on the first display mode and the second display mode, then the display terminal is adjusted.

[0076] It should be understood that poor display quality of the image projected onto a display terminal is often related to whether the display mode of the image to be displayed matches the display mode of the display terminal. In this embodiment, the initial screen width and initial screen height of the image to be displayed, as well as the screen height and screen width of the display terminal, can be obtained first. The initial screen width is the pixel value in the horizontal direction of the image to be displayed, and the initial screen height is the pixel value in the vertical direction. Similarly, the screen width and screen height are also measured in pixel values. Then, a first display mode corresponding to the image to be displayed can be determined based on the initial screen width and initial screen height, and a second display mode corresponding to the display terminal can be determined based on the screen width and screen height of the display terminal. Both the first and second display modes can be either landscape or portrait modes.

[0077] In a specific application scenario, the ratio Bp between the initial screen width and the initial screen height of the image to be displayed can be calculated first, where Bp = initial screen width / initial screen height, or Bp = initial screen height / initial screen width. Then, the first display mode corresponding to the image to be displayed can be determined based on the relationship between Bp and a preset value. The preset value can be 1. For example, when Bp = initial screen width / initial screen height, if the calculated Bp is less than 1, such as 9 / 16, the first display mode corresponding to the image to be displayed can be determined to be portrait mode; if the calculated Bp is greater than or equal to 1, such as 16 / 9, the first display mode corresponding to the image to be displayed can be determined to be landscape mode. Similarly, when Bp = initial screen height / initial screen width, if the calculated Bp is greater than 1, the first display mode corresponding to the image to be displayed can be determined to be portrait mode; if the calculated Bp is less than or equal to 1, the first display mode corresponding to the image to be displayed can be determined to be landscape mode. Similarly, the second display mode corresponding to the display terminal can also be determined in a similar way, that is, BT = screen width / screen height, or BT = screen height / screen width.

[0078] Here, after obtaining the first display mode corresponding to the screen to be displayed and the second display mode corresponding to the display terminal, the display terminal can determine whether to adjust the display terminal based on the first display mode and the second display mode, and can determine the target angle and target direction of the display terminal based on the first display mode and the second display mode.

[0079] Specifically, when the first display mode and the second display mode are not the same, for example, such as Figure 2bAs shown, when the first display mode is portrait mode and the second display mode is landscape mode, it can be determined that the display terminal needs to be adjusted, and the target angle and direction of the adjustment can be determined to be 90 degrees vertically, so that the display terminal is adjusted to the target angle and direction. Figure 2b In this context, O represents the center point of the display terminal and the screen to be displayed. The X-axis is horizontal, and the Y-axis is vertical, with the Y-axis also representing the forward display direction of the screen. During the adjustment process, the center point of the display terminal and the screen to be displayed remains unchanged. Alternatively, when the first display mode is landscape mode and the second display mode is portrait mode, the display terminal can be adjusted, and the target angle and direction of the adjustment can be determined to be 0 degrees horizontally, so that the display terminal is adjusted to the target angle and direction.

[0080] S102. Determine the second adjustment rate and the second adjustment direction of the image to be displayed based on the first adjustment rate and the first adjustment direction;

[0081] In one possible implementation, the determined second adjustment rate is the same as the first adjustment rate, while the determined second adjustment direction is opposite to the first adjustment direction. For example, when the first adjustment rate is 1 degree / s and the first adjustment direction is clockwise, the determined second adjustment angle is also 1 degree / s, and the determined second adjustment direction is counterclockwise.

[0082] S103. Adjust the screen to be displayed based on the second adjustment rate and the second adjustment direction, and display the adjusted screen to be displayed in the display terminal adjusted according to the first adjustment rate and the first adjustment direction.

[0083] In this embodiment, after determining the second adjustment rate and second adjustment direction corresponding to the image to be displayed, the display terminal can adjust the image to be displayed based on the second adjustment rate and second adjustment direction while adjusting the display terminal according to the first adjustment rate and first adjustment direction. For example, the second adjustment rate and second adjustment direction of the image to be displayed can be adjusted by calling the setRotate(-R) function of the Matrix object, and the adjusted image to be displayed can be synchronously displayed on the display terminal during the adjustment process. This ensures that the image displayed on the display terminal is always displayed to the user in a positive orientation while the display terminal is adjusted to the target angle, improving the image display effect and enhancing the user's viewing experience.

[0084] In one possible implementation, the display terminal may have a pre-set correspondence between a first adjustment rate and a first adjustment direction, and a second adjustment rate and a second adjustment direction. When the display terminal needs to be adjusted, it can first acquire the first adjustment rate and the first adjustment direction; then, based on the first adjustment rate, the first adjustment direction, and the pre-set correspondence, it can determine the second adjustment rate and the second adjustment direction of the image to be displayed. Therefore, when adjusting the display terminal according to the first adjustment rate and the first adjustment direction, the image to be displayed can be adjusted simultaneously according to the second adjustment rate and the second adjustment direction, and the adjusted image to be displayed can be displayed on the adjusted display terminal, thereby achieving synchronous adjustment between the display terminal and the image to be displayed and improving the image display effect.

[0085] In this embodiment of the application, when adjusting the display terminal in landscape mode, the target angle can be the angle of the display terminal in portrait mode, and when adjusting the display terminal in portrait mode, the target angle can be the angle of the display terminal in landscape mode.

[0086] In another possible implementation, the image to be displayed can also be adjusted based on the adjustment angle and adjustment direction of the display terminal. Specifically, after acquiring the first adjustment rate and the first adjustment direction of the display terminal, the display terminal can also acquire the adjustment time of the display terminal, and determine the first adjustment angle of the display terminal based on the first adjustment rate and the adjustment time; or the first adjustment angle of the display terminal can be directly measured by an angle sensor. After determining the first adjustment angle of the display terminal, the display terminal can first determine the second adjustment angle and the second adjustment direction of the image to be displayed based on the first adjustment angle and the first adjustment direction, wherein the second adjustment angle is the same as the first adjustment angle and the second adjustment direction is opposite to the first adjustment direction; then the image to be displayed can be adjusted according to the second adjustment angle and the second adjustment direction, and the adjusted image to be displayed can be displayed on the display terminal adjusted according to the first adjustment angle and the first adjustment direction.

[0087] Optionally, adjusting the image to be displayed based on the second adjustment angle and the second adjustment direction, and displaying the adjusted image to be displayed in a display terminal adjusted according to the first adjustment angle and the first adjustment direction, may include:

[0088] Step a: Determine the stretching ratio of the image to be displayed based on the second adjustment angle;

[0089] In one possible implementation, the stretching ratio can be determined by combining the screen height of the display terminal and the initial screen width of the image to be displayed. This ensures that when the display terminal and the image to be displayed are adjusted to a target angle, the image to be displayed will primarily fill the screen width of the display terminal. The target angle can be determined based on specific circumstances. For example, when adjusting the display terminal in landscape mode, the target angle can be the angle of the display terminal in portrait mode; conversely, when adjusting the display terminal in portrait mode, the target angle can be the angle of the display terminal in landscape mode. The stretching ratio refers to the factor by which the initial screen height and initial screen width of the image to be displayed are magnified.

[0090] Specifically, such as Figure 3 As shown, determining the stretching ratio of the image to be displayed based on the second adjustment angle may include:

[0091] S301. Obtain the screen height of the display terminal and the initial screen width of the image to be displayed;

[0092] S302. Determine the target screen width of the screen to be displayed based on the screen height of the display terminal, the initial screen width of the screen to be displayed, and the second adjustment angle;

[0093] Here, determining the target screen width of the image to be displayed based on the screen height of the display terminal, the initial screen width of the image to be displayed, and the second adjustment angle may include:

[0094] The target screen width of the image to be displayed is determined using the following formula:

[0095] Width tar =2R*(Height) tv Width pri ) / π+Width pri ;

[0096] Among them, Width tar R is the target screen width of the image to be displayed, and R is the second adjustment angle. tv Width is the screen height of the display terminal. pri The initial screen width is the width of the image to be displayed.

[0097] S303. Determine the stretching ratio of the image to be displayed based on the initial image width and the target image width.

[0098] Specifically, determining the stretching ratio of the image to be displayed based on the initial image width and the target image width may include:

[0099] The scaling factor Pro of the image to be displayed is determined according to the following formula:

[0100] Pro = Width tar / Width pri .

[0101] In another possible implementation, the stretching ratio can be determined by combining the screen width of the display terminal and the initial height of the image to be displayed, so that when the display terminal and the image to be displayed are adjusted to the target angle, the image to be displayed can preferentially fill the screen height of the display terminal. Specifically, as shown... Figure 4 As shown, determining the stretching ratio of the image to be displayed based on the second adjustment angle may include:

[0102] S401. Obtain the screen width of the display terminal and the initial screen height of the image to be displayed;

[0103] S402. Determine the target image height of the image to be displayed based on the screen width of the display terminal, the initial image height of the image to be displayed, and the second adjustment angle.

[0104] Here, determining the target image height of the image to be displayed based on the screen width of the display terminal, the initial image height of the image to be displayed, and the second adjustment angle may include:

[0105] The target screen height of the image to be displayed is determined using the following formula:

[0106] Height tar =2R*(Width) tv -Height pri ) / π+Height pri ;

[0107] Among them, Heigh tar R is the target screen width of the image to be displayed, and R is the second adjustment angle. tv The screen width and height of the display terminal are given. pri The initial screen height is the height of the image to be displayed.

[0108] S403. Determine the stretching ratio of the image to be displayed based on the initial image height and the target image height.

[0109] Specifically, determining the stretching ratio of the image to be displayed based on the initial image height and the target image height may include:

[0110] The stretching ratio Pro of the image to be displayed is determined according to the following formula:

[0111] Pro = Height tar / Height pri .

[0112] Step b: Stretch the image to be displayed using the stretching ratio to obtain the target display image;

[0113] Step c: Adjust the target display screen based on the second adjustment angle and the second adjustment direction, and display the adjusted target display screen in the display terminal adjusted according to the first adjustment angle and the first adjustment direction.

[0114] It should be noted that after determining the stretching ratio of the image to be displayed, the display terminal can stretch the image to be displayed using the stretching ratio. By stretching the image to be displayed, a target display image is obtained. The target display image is then adjusted based on the second adjustment angle and the second adjustment direction. This reduces the display blank space on the display terminal when the adjusted target display image is displayed, thereby improving the image display effect and enhancing the user's viewing experience. Here, the display terminal can stretch the image to be displayed by calling the `setScale(Pro, Pro)` method of the `Matrix` object and the `createBitmap` method of the `Bitmap` object to obtain the stretched target display image. That is, during the synchronous adjustment of the image to be displayed, the image can also be stretched according to the second adjustment angle to reduce the display blank space when the image is displayed on the display terminal, improving the image display effect and enhancing the user's viewing experience.

[0115] For example, according to Figure 2b When adjusting the display terminal, the screen to be displayed can be stretched and synchronously adjusted to ensure that the screen on the display terminal can always be displayed to the user in a positive orientation. For example, at a specific moment, it can be adjusted as follows: Figure 4a The forward display method shown is used to display the image on the display terminal; for example, when the display terminal is adjusted to the target angle, it can be displayed as follows: Figure 4b The forward display method shown is used to display the image on the display terminal.

[0116] It should be understood that in application scenarios where the stretching ratio is determined by combining the screen height of the display terminal and the initial screen width of the image to be displayed, after stretching the image to be displayed using the stretching ratio to obtain the target display image, the process may further include:

[0117] Step d: Obtain the target screen height of the target display screen;

[0118] Step e: Determine whether the height of the target image is greater than the screen height of the display terminal;

[0119] Step f: If the height of the target image is greater than the screen height of the display terminal, then adjust the target image height and target image width according to the screen height of the display terminal.

[0120] For steps d to f above, the stretching ratio is determined based on prioritizing filling the screen width of the display terminal. Therefore, the target screen width of the target display image obtained based on the stretching ratio often does not exceed the screen width of the display terminal, but the target screen height may exceed the screen height of the display terminal. In this case, if the target display image is directly displayed on the display terminal, the portion of the target display image exceeding the screen height may not be displayed on the display terminal, resulting in incomplete display and significantly reducing the display effect. Therefore, in this scenario, when it is determined that the target screen height exceeds the screen height (i.e., when it is determined that the target screen height is greater than the screen height), the display terminal can adjust the target screen height and target screen width according to the screen height. For example, the target screen height can be adjusted to the screen height, and the adjustment ratio can be determined according to the target screen height and the screen height. Then, the target screen width can be adjusted proportionally according to the adjustment ratio to ensure that the target screen is displayed completely and that the image is not distorted, thereby improving the image display effect and enhancing the user's viewing experience.

[0121] It should be understood that in application scenarios where the stretching ratio is determined by combining the screen width of the display terminal and the original image height of the image to be displayed, after scaling the image to be displayed using the stretching ratio to obtain the target display image, the process may further include:

[0122] Step g: Obtain the target screen width of the target display screen;

[0123] Step h: Determine whether the width of the target image is greater than the screen width of the display terminal;

[0124] Step i: If the width of the target image is greater than the screen width of the display terminal, then adjust the target image height and target image width according to the screen width of the display terminal.

[0125] For steps g to i above, the stretching ratio is determined based on prioritizing filling the screen height of the display terminal. Therefore, the target image height of the target display image obtained based on the stretching ratio often does not exceed the screen height of the display terminal, but the target image width may exceed the screen width of the display terminal. In this case, if the target image is directly displayed on the display terminal, the portion of the target image exceeding the screen width may not be displayed on the display terminal, resulting in incomplete display and significantly reducing the image display effect. Therefore, in this scenario, when it is determined that the target image width exceeds the screen width (i.e., when it is determined that the target image width is greater than the screen width), the display terminal can adjust the target image height and target image width according to the screen width. For example, the target screen width of the target display can be adjusted to the screen width, and the adjustment ratio can be determined according to the target screen width and the screen width. Then, the target screen height can be adjusted proportionally according to the adjustment ratio to ensure that the target display is displayed completely and that the image is not distorted, thereby improving the display effect and enhancing the user's viewing experience.

[0126] In this embodiment, when a screen to be displayed is acquired, a driving device corresponding to the display terminal is activated. The driving device is connected to the display terminal to drive the display terminal to move. A first adjustment rate and a first adjustment direction of the display terminal are acquired. The screen to be displayed is the display image formed by the display terminal. A second adjustment rate and a second adjustment direction of the screen to be displayed are determined based on the first adjustment rate and the first adjustment direction. The screen to be displayed is adjusted based on the second adjustment rate and the second adjustment direction, and the adjusted screen to be displayed is displayed on the display terminal adjusted according to the first adjustment rate and the first adjustment direction. That is, in this embodiment, when displaying a screen to be displayed, the display terminal can be adjusted. When adjusting the display terminal, a second adjustment rate and a second adjustment direction of the screen to be displayed can be determined based on the first adjustment rate and the first adjustment direction of the display terminal. This allows for synchronous adjustment of the screen to be displayed based on the second adjustment rate and the second adjustment direction, ensuring that the display image is always displayed to the user in a positive orientation during the adjustment process, improving the display effect and enhancing the user's viewing experience.
