[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without making any creative efforts shall fall within the scope of protection of this application.

[0048] Screen projection reverse control is a technology that uses the screen projection function to display the content of the projected device on the projecting device, and remotely control the projected device through the content displayed on the projecting device.

[0049] For ease of description, the screen projection device will be referred to as a touch device, and the screen projected device will be referred to as a display device.

[0050] In actual applications, there may be a situation where the screen display interface of the display device is much larger than the screen display interface of the touch device. In this case, when the user needs to control the display device through the touch device, if the user's fingers are relatively large, the actual touched position and the required touched position may deviate due to the small screen display interface of the touch device, resulting in invalid control of the display device, thereby affecting the user experience.

[0051] In view of this, an embodiment of the present application provides a display control method, which is applied to a touch device, and the method includes: based on the communication connection between the display device and the display device, synchronously displaying the target screen displayed on the display device on the first display interface, and the screen size of the display device is larger than the screen size of the touch device; in response to the triggering operation of the magnifying glass control, displaying the second display interface in the designated display area of ​​the touch device, the second display interface includes a focus frame, and the focus frame is used to determine the area to be magnified on the target screen; displaying the target local display screen formed by magnifying the area to be magnified on the first display interface. Through the display control method provided by the present application, the display device can be projected to the touch device to display the target screen for partial magnification, and the magnified target local display screen can be displayed on the first display interface, so that the user can perform targeted control of the display device through the target local display interface, thereby effectively avoiding the occurrence of invalid control of the display device, which is conducive to improving the user experience.

[0052] In some optional implementation scenarios, the touch device can be used in a smart interactive screen device. The display device can be a touch device with a large display screen used in a conference room, a television, or a billboard. The display device can have a touch function.

[0053] According to an embodiment of the present application, an embodiment of a display control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0054] In this embodiment, a display control method is provided, which can be used for the above-mentioned touch devices, such as mobile phones, tablet computers, etc. FIG1 is a flow chart of the display control method according to an embodiment of the present application. As shown in FIG1 , the flow chart includes the following steps:

[0055] Step S101 : Based on the communication connection with the display device, the target image displayed on the display device is synchronously displayed on the first display interface.

[0056] In an embodiment of the present application, to achieve reverse screen projection control, based on the communication connection between the touch device and the display device, the display device projects the target image displayed on the touch device for synchronous display. The screen size of the display device is larger than the screen size of the touch device. The first display interface can be a partial or full display interface of the touch device.

[0057] Step S102 : In response to the triggering operation of the magnifying glass control, a second display interface is displayed in a designated display area of ​​the touch device.

[0058] In the embodiment of the present application, the magnifying glass control is a control for magnifying a portion of a displayed image. In response to a triggering operation of the magnifying glass control, a second display interface is displayed within a designated display area of ​​the touch-sensitive device, and a focus frame displayed within the second display interface determines the area to be magnified on the target image.

[0059] In one example, the designated display area may be a partial display area on the first display interface, i.e., the second display interface may completely cover the first display interface. In another example, the designated display area may include a partial display area on the first display interface, i.e., the second display interface may partially cover the first display interface.

[0060] Step S103 : displaying a target partial display image formed by enlarging the area to be enlarged on the first display interface.

[0061] In an embodiment of the present application, a target local display screen after the area to be enlarged is determined, and then displayed on the first display interface, so that the user can directly touch the position actually required to be touched according to the enlarged target local display screen, thereby effectively avoiding the occurrence of invalid control, thereby helping to enhance the user experience.

[0062] The display control method provided in this embodiment can project the display device to a touch-sensitive device to partially enlarge the target display screen, and display the enlarged target local display screen on the first display interface, so that the user can perform targeted control of the display device through the target local display interface, thereby effectively avoiding invalid control of the display device and improving the user experience.

[0063] In some optional embodiments, the second display interface and the first display interface display the same image, allowing the user to quickly determine the area to be magnified while moving the focus frame, avoiding invalid magnification, thereby improving the interactivity of the touch device and enhancing the user experience. That is, the first and second display interfaces of the touch device can both display the target image's real-time streaming data transmitted by the display device synchronously, thereby ensuring that the first and second display interfaces display the same image.

[0064] In this embodiment, a display control method is provided, which can be used for the above-mentioned touch devices, such as mobile phones, tablet computers, etc. FIG2 is a flow chart of the display control method according to the embodiment of the present application. As shown in FIG2 , the flow chart includes the following steps:

[0065] Step S201: Based on the communication connection with the display device, the target image displayed on the display device is synchronously displayed on the first display interface. Please refer to step S101 of the embodiment shown in FIG1 for details, which will not be repeated here.

[0066] Step S202: In response to the triggering operation of the magnifying glass control, a second display interface is displayed in the designated display area of ​​the touch device. Please refer to step S102 of the embodiment shown in FIG1 for details, which will not be repeated here.

[0067] Step S203 : displaying a target partial display screen formed by enlarging the area to be enlarged on the first display interface.

[0068] Specifically, the above step S203 includes:

[0069] Step S2031 , tracking and determining the current display position of the focus frame on the second display interface.

[0070] In an embodiment of the present application, in order to determine the screen display area where the target image needs to be enlarged, the current display position of the focus frame on the second display interface is tracked and determined, so that the position of the area to be enlarged in the first display interface can be determined through the display position.

[0071] Step S2032: determining the area to be magnified on the target screen based on the size ratio and display position between the focus frame and the second display interface.

[0072] In the embodiment of the present application, the interface size of the second display interface is smaller than that of the first display interface. Therefore, to determine the area to be magnified on the target screen, the area range of the area to be magnified on the target screen is determined based on the size ratio between the focus frame and the second display interface, and then the area to be magnified is determined in combination with the display position, so that it can be subsequently displayed in a targeted manner on the second display interface.

[0073] Step S2033: Displaying the target partial display image after the area to be enlarged is enlarged on the first display interface.

[0074] In some optional implementations, the second display interface is a thumbnail window of the first display interface, and step S2033 includes:

[0075] Step a1: Obtain the image magnification factor.

[0076] Step a2: amplify the local display image corresponding to the area to be magnified in the target image according to the image magnification factor to obtain the target local display image.

[0077] Step a3: display the target partial display screen on the first display interface.

[0078] Specifically, to facilitate targeted magnification of the area to be magnified, a target partial display image is displayed on the first display interface. A screen magnification factor is obtained, and then, if the area to be magnified is clear, the magnification factors of the horizontal and vertical coordinate components of each touch coordinate within the partial display image corresponding to the area to be magnified in the target image are determined based on the screen magnification factor. The horizontal and vertical coordinates of each touch coordinate are then specifically magnified to obtain the target partial display image, which is then displayed on the first display interface. For example, if the screen magnification factor is 4, the magnification factors of the horizontal and vertical coordinate components of each touch coordinate within the partial display image corresponding to the area to be magnified can be determined to be 2. The horizontal and vertical coordinates of each touch coordinate are then magnified by a factor of 2 to obtain the target partial display image, which is then displayed on the first display interface.

[0079] In one example, the image magnification factor can be determined based on the size ratio between the focus frame and the second display interface. When the size of the focus frame can be dynamically adjusted, the touch device can also quickly determine the image magnification factor based on the adjusted focus frame, thereby improving the flexibility of the touch device in performing targeted magnification of a local display image and meeting the user's usage needs. The image magnification factor is the inverse of the size ratio. For example: if the size ratio between the focus frame and the second display interface is 1 / 4, the image magnification factor is 4. If the size ratio between the focus frame and the second display interface is 1 / 6, the image magnification factor is 6.

[0080] In another example, the image magnification factor can be obtained through preset configuration parameters, thereby helping to improve the magnification response efficiency.

[0081] The display control method provided in this embodiment can specifically magnify the target local display screen after the magnified area is magnified based on the size ratio between the focus frame and the second display interface, so that the target local display screen displayed on the first display interface can meet the user's touch requirements, thereby facilitating the user to perform targeted control.

[0082] In some optional implementation scenarios, before the touch operation is performed on the magnifying glass control, the target screen displayed on the first display interface 10 may be as shown in FIG3 . The first display interface 10 may have multiple icons. After the magnifying glass control 20 is triggered, as shown in FIG4 , the second display interface 30 may be displayed on the lower left corner (specified display area) of the first display interface 10. The second display interface 30 includes a focus frame 31. The area currently selected by the focus frame 31 is the area to be magnified. After the area to be magnified is magnified, the target partial display screen shown in FIG5 is displayed on the first display interface 10.

[0083] In this embodiment, a display control method is provided, which can be used for the above-mentioned touch-sensitive devices, such as mobile phones, tablet computers, etc. FIG6 is a flow chart of the display control method according to the embodiment of the present application. As shown in FIG6 , the flow chart includes the following steps:

[0084] Step S601: Based on the communication connection with the display device, the target image displayed on the display device is synchronously displayed on the first display interface.

[0085] Step S602 : In response to the triggering operation of the magnifying glass control, a second display interface is displayed in a designated display area of ​​the touch device.

[0086] Step S603 : Displaying a target partial display screen formed by enlarging the area to be enlarged on the first display interface.

[0087] Step S604 , responding to the target touch operation, identifying the display position of the target in the target partial display screen.

[0088] In the embodiment of the present application, responding to a touch operation on a target indicates that the user needs to control the target. Therefore, in order to facilitate the target on the display device to respond to the touch operation, the display position of the target on the target partial display screen is identified. For example, the target can be any touch point on the target partial display screen, or it can be a specific icon or a specified gesture.

[0089] Step S605 : determining the display coordinates of the target when the touch device displays the target image based on the display position.

[0090] In an embodiment of the present application, in order to project a target image from a display device onto the first display interface of a touch-control device for display, the streaming media data of the target image is scaled down based on the ratio between the fourth display interface and the first display interface, and then transmitted to the touch-control device, so that the touch-control device can synchronously display the target image on the first display interface based on the received scaled-down streaming media data. The fourth display interface is the display interface on which the display device displays the target image.

[0091] However, since the target partial display screen currently displayed on the first display interface is obtained by enlarging the partial display screen corresponding to the area to be enlarged in the target screen according to the screen magnification factor, in order to facilitate the display device to clearly understand the position that needs to respond, the display coordinates of the target when the touch device displays the target screen are determined based on the display position.

[0092] In one example, the display coordinates can be determined by determining the touch coordinates of the target when the touch device is currently displaying the target's partial display image, and then performing targeted reduction based on the magnification factors of the horizontal and vertical coordinate components of the touch coordinates to obtain the display coordinates. In another example, if the focus frame has a coordinate offset during movement, after performing targeted reduction based on the magnification factors of the horizontal and vertical coordinate components of the touch coordinates, the display coordinates are determined in combination with the coordinate offset, thereby helping to ensure that the display device can more accurately simulate the response of the target when the touch device is touched.

[0093] In step S606 , the display coordinates are sent to the display device to control the target to be touched on the display device.

[0094] The display control method provided in this embodiment can expand the user's visible area of ​​the target image by magnifying the target partial display screen, thereby enabling the user to perform targeted touch control on the target. Furthermore, after the target is touched, the display coordinates of the target on the target image are determined based on the target's display position in the target partial display screen and then sent to the display device. This ensures that the display device can more accurately simulate the response of the target when touched on the touch device, effectively ensuring the effectiveness of the touch control operation and helping to enhance the user experience.

[0095] In some optional implementations, the display control method further includes:

[0096] In step S607, in response to the closing operation of the magnifier control, the screen displayed on the first display interface is restored from the target partial display screen to the target screen. In other words, in response to the closing operation of the magnifier control, it indicates that the user no longer needs the first display interface to display the magnified area display image, and the screen displayed on the first display interface is restored from the target partial display screen to the target screen. This makes the touch device more flexible in displaying the target screen, thereby enhancing the practicality of the touch device.

[0097] In other optional embodiments, the magnifying glass control is provided on a third display interface, and the third display interface is adjacent to the first display interface. For example, the third display interface can be located anywhere around the first display interface, such as to the left, right, above, or below the first display interface. This can be set as needed and is not limited in this application. Preferably, as shown in FIG4 , the third display interface can be deployed below the first display interface, so that when the user touches the magnifying glass control through the third display interface, it will not block the user's view of the first display interface.

[0098] In some examples, the third display interface is a function bar, thereby being able to reasonably utilize the display space of the touch device display interface.

[0099] In some optional implementation scenarios, in the process of synchronously displaying the target screen displayed by the display device on the first display interface, it is possible to monitor whether the magnifying glass control is triggered. If the magnifying glass control is triggered, the area selected by the focus frame in the second display interface is partially magnified, and then the enlarged target local display screen is displayed in the first display interface. If the user performs a touch operation on the target in the target local display screen, the display coordinates of the target on the first display interface are determined based on the display position of the target in the target local display screen, and then the display coordinates are sent to the display device so that the display device can respond in a targeted manner based on the received display coordinates, thereby effectively ensuring the effectiveness of the touch operation and helping to improve the user experience. If the magnifying glass control is closed, the original target screen is restored and displayed on the first display interface.

[0100] If the magnifying glass control is not triggered during the process of synchronously displaying the target image displayed by the display device on the first display interface, the first display interface only displays the target image.

[0101] In this embodiment, a display control device is also provided, which is used to implement the above-mentioned embodiments and preferred embodiments.
