[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0047] 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.

[0048] For ease of description, the screen projection device will be described as a touch device, and the screen projected device will be described as a display device.

[0049] 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.

[0050] 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 with 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 specified 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 enlarged 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.

[0051] In some optional implementation scenarios, the touch device may be applied to a smart interactive screen device. The display device may be a touch device with a large display screen applied to a conference room, a television, or a billboard, etc. The display device may have a touch function.

[0052] According to an embodiment of the present application, a display control method embodiment 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.

[0053] In this embodiment, a display control method is provided, which can be used for the above-mentioned touch-control devices, such as mobile phones, tablet computers, etc. Figure 1 is a flow chart of a display control method according to an embodiment of the present application, such as Figure 1 As shown, the process includes the following steps:

[0054] Step S101: Based on the communication connection with the display device, the target picture displayed on the display device is synchronously displayed on the first display interface.

[0055] In the implementation mode of the present application, in order to realize reverse control of screen projection, based on the communication connection between the touch device and the display device, the display device projects the target screen displayed by itself on the touch device for synchronous display. Among them, 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.

[0056] Step S102, in response to the triggering operation of the magnifying glass control, displaying a second display interface in a designated display area of ​​the touch device.

[0057] In the embodiment of the present application, the magnifying glass control is a control for magnifying a local display screen. 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, so that the area to be magnified on the target screen is determined by a focus frame displayed in the second display interface.

[0058] In one example, the designated display area may be a partial display area on the first display interface, that is, the second display interface may be completely covered on the first display interface. In another example, the designated display area may include a partial display area on the first display interface, that is, the second display interface partially covers the first display interface.

[0059] Step S103 , displaying a target partial display screen formed by enlarging the area to be enlarged on the first display interface.

[0060] In an implementation manner 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.

[0061] The display control method provided in this embodiment can project the display device to the touch device to partially enlarge the display target 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 helping to improve the user experience.

[0062] In some optional implementations, the second display interface has the same display screen as the first display interface, so that the user can quickly determine the area to be magnified when moving the focus frame, avoiding invalid magnification, thereby improving the interactivity of the touch device and helping to enhance the user experience. That is, in the first display interface and the second display interface of the touch device, both can be synchronously displayed according to the real-time streaming media data of the target screen sent by the display device, thereby ensuring that the display screens of the first display interface and the second display interface are the same.

[0063] In this embodiment, a display control method is provided, which can be used for the above-mentioned touch-control devices, such as mobile phones, tablet computers, etc. Figure 2 is a flow chart of a display control method according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0064] 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. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0065] Step S202: 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. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0066] Step S203 , displaying a target partial display screen formed by enlarging the area to be enlarged on the first display interface.

[0067] Specifically, the above step S203 includes:

[0068] Step S2031, tracking and determining the current display position of the focus frame on the second display interface.

[0069] 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.

[0070] Step S2032: determining the area to be enlarged on the target screen based on the size ratio and display position between the focus frame and the second display interface.

[0071] 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, in order 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 displayed in a targeted manner on the second display interface later.

[0072] Step S2033: displaying the target partial display screen after the to-be-enlarged area is enlarged on the first display interface.

[0073] In some optional implementations, the second display interface is a thumbnail window of the first display interface, and the above step S2033 includes:

[0074] Step a1, obtaining the image magnification factor.

[0075] Step a2, enlarging the local display picture corresponding to the area to be enlarged in the target picture according to the picture magnification factor to obtain the target local display picture.

[0076] Step a3: display the target partial display screen on the first display interface.

[0077] Specifically, in order to facilitate targeted magnification of the area to be magnified, the target partial display screen is displayed on the first display interface, and the screen magnification factor is obtained. Then, when the area to be magnified is clear, the magnification factors of the horizontal and vertical coordinate components of each touch coordinate in the local display screen corresponding to the area to be magnified in the target screen are determined according to the screen magnification factor, and then the horizontal and vertical coordinates of each touch coordinate are targetedly magnified to obtain the target partial display screen, and displayed on the first display interface. For example: if the screen magnification factor is 4, it can be determined that the magnification factors of the horizontal and vertical coordinate components of each touch coordinate in the local display screen corresponding to the area to be magnified are both 2, and then the horizontal and vertical coordinates of each touch coordinate are enlarged by 2 times, so as to obtain the target partial display screen, and display it on the first display interface.

[0078] 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 to perform targeted magnification on the local display screen and meeting the user's usage needs. The image magnification factor is the reciprocal 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.

[0079] In another example, the picture magnification factor can be obtained through preset configuration parameters, which helps to improve the magnification response efficiency.

[0080] The display control method provided in this embodiment can specifically magnify the target local display screen after the magnified area is enlarged 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.

[0081] 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 follows: Figure 3 As shown. The first display interface 10 may have multiple icons. After the magnifying glass control 20 is triggered, as shown Figure 4 As shown, the second display interface 30 can 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 first display interface 10 is displayed as shown. Figure 5 The target partial display screen is shown.

[0082] In this embodiment, a display control method is provided, which can be used for the above-mentioned touch-control devices, such as mobile phones, tablet computers, etc. Figure 6 is a flow chart of a display control method according to an embodiment of the present application, such as Figure 6 As shown, the process includes the following steps:

[0083] Step S601: Based on the communication connection with the display device, the target picture displayed on the display device is synchronously displayed on the first display interface.

[0084] 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.

[0085] Step S603 , displaying a target partial display screen formed by enlarging the area to be enlarged on the first display interface.

[0086] Step S604, responding to the target touch operation, identifying the display position of the target in the target partial display screen.

[0087] 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 in the target partial display screen is identified. For example, the target can be any touch point on the target partial display screen, or a specific icon or a specified gesture.

[0088] Step S605 , based on the display position, determining the display coordinates of the target when the touch-controlled device displays the target image.

[0089] In the embodiment of the present application, in order to project the target image from the display device to the first display interface of the touch device for display, it is necessary to reduce the streaming media data of the target image according to the ratio between the fourth display interface and the first display interface and transmit it to the touch device, so that the touch device can synchronously display the target image on the first display interface according to the received reduced streaming media data. The fourth display interface is the display interface of the display device displaying the target image.

[0090] 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.

[0091] In one example, the display coordinates can be determined in the following manner: determine the touch coordinates of the target when the touch device displays the target partial display screen, and then perform targeted reduction according to the magnification of the horizontal and vertical coordinate components of the touch coordinates, so as to obtain the display coordinates. In another example, if the focus frame has a coordinate offset during the movement process, after performing targeted reduction according to the magnification 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.

[0092] In step S606, the display coordinates are sent to the display device to control the target to be touched on the display device.

[0093] The display control method provided in this embodiment can expand the visible area for users to observe the target image by enlarging the target partial display screen, thereby enabling users to perform targeted touch control on the target. After the target is touched, the display coordinates of the target displayed on the target image can be determined based on the display position of the target in the target partial display screen, and then sent to the display device, which can ensure that the display device can more accurately simulate the response generated by the target when the touch device is touched, thereby effectively ensuring the effectiveness of the touch control operation and helping to improve the user experience.

[0094] In some optional implementations, the display control method further includes:

[0095] 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. That is, in response to the closing operation of the magnifier control, it indicates that the user does not need the first display interface to display the enlarged regional display image, and then the screen displayed on the first display interface is restored from the target partial display screen to the target screen, so that the touch device displays the target screen in a more flexible manner, which helps to enhance the practicality of the touch device.

[0096] In some other optional implementations, the magnifying glass control is set on the third display interface, and the third display interface is adjacent to the first display interface. For example, the third display interface can be located at any position around the first display interface, such as: on the left, right, above or below the first display interface, and can be set according to needs, which is not limited in this application. Preferably, if Figure 4 As shown, 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 sight of the first display interface.

[0097] 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.

[0098] 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 enlarged, 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 according to 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 according to 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.

[0099] If the magnifying glass control has not been triggered during the process of synchronously displaying the target picture displayed by the display device on the first display interface, the first display interface only displays the target picture.
