[0021] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order of functions executed by these devices, modules or units or their interdependent relationships.

[0022] It should be noted that the modifications of "one" and "plural" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0023] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0024] Please refer to Figure 1 , which shows the flow of some embodiments of the display control method according to the present disclosure. The display control method is applied to a mobile terminal. Among them, the mobile terminal and the screen device establish a communication connection so that the screen device displays the display content of the mobile terminal. Usually, after the mobile terminal and the screen device establish a communication connection, the screen device can display the display content of the mobile terminal.

[0025] As Figure 1As shown, the display control method includes the following steps:

[0026] Step 101, determine the current display mode of the mobile terminal.

[0027] The display mode can be a mode for displaying the content of an object on the mobile terminal on a screen device. The display mode can include at least one of the following: the display mode set by default in the above mobile terminal; the display mode customized by the user.

[0028] The execution entity of the display control method can determine the current display mode of the mobile terminal. Optionally, the above execution entity can determine the display mode selected by the user from multiple display modes as the above current display mode.

[0029] Step 102, receive user operation information.

[0030] The user operation information is used to control the above mobile terminal to display the content of the target object on the above screen device. Among them, the user operation information is used to indicate various user operations performed by the user on the target object. Optionally, the user operation can include an open operation of the target object.

[0031] The above execution entity can receive user operation information. In some scenarios, if user operation information is received, the above execution entity can control the mobile terminal to display the content of the target object on the above screen device.

[0032] Step 103, determine whether the target object has the display permission to display content on the above screen device according to the above current display mode.

[0033] The above execution entity can determine whether the target object has the display permission to display content on the above screen device according to the current display mode of the above mobile terminal. In some scenarios, the user can preset at least one object that can display content on the above screen device in the above current display mode. If the target object is an object set by the user for the above current display mode, the above execution entity can determine that the target object has the above display permission. If the target object is not an object set by the user for the above current display mode, the above execution entity can determine that the target object does not have the above display permission.

[0034] Step 104, in response to the target object having the above display permission, control the above mobile terminal to display the content of the target object on the above screen device.

[0035] In response to the target object having the above display permission, the above execution entity can control the above mobile terminal to display the content of the target object on the above screen device.

[0036] In some embodiments, Figure 1The process shown may further include step 104.

[0037] Step 105, in response to the target object not having the above display permission, rejecting the mobile terminal from displaying the content of the target object on the above screen device.

[0038] In response to the target object not having the above display permission, the above execution entity rejects the mobile terminal from displaying the content of the target object on the above screen device.

[0039] Thus, if user operation information indicating that the user performs a user operation on the target object is received, the content of the target object is not directly displayed on the screen device, but rather, according to the current display mode of the mobile terminal, it is determined whether the target object has the display permission to display content on the screen device, and on the premise that the target object has the display permission, the mobile terminal is controlled to display the content of the target object on the screen device. Thus, after the mobile terminal and the screen device establish a communication connection, only the content of the target object with the display permission on the mobile terminal can be displayed on the screen device. Thereby, the security of displaying the content of the target object on the mobile terminal on the screen device can be improved.

[0040] In some embodiments, the above user operation information is used to indicate the user operation performed by the user on the target object on the above mobile terminal or the above screen device.

[0041] The object identifier (e.g., icon) of the object on it can be displayed on the mobile terminal. After establishing a communication connection with the mobile terminal, the object identifier of the object on the mobile terminal can also be displayed on the screen device. Optionally, the user operation can be a triggering operation of the object identifier of the object.

[0042] It can be understood that if the user performs a user operation on the target object on the screen device, the screen device can send the user operation information to the mobile terminal. Thus, the above execution entity can receive the user operation information sent by the screen device.

[0043] Thus, after the mobile terminal and the screen device establish a communication connection, the user performing a user operation on the target object on the mobile terminal or the screen device can trigger the display of the content of the target object on the screen device.

[0044] In some embodiments, during the process of the above screen device displaying the content of the object on the above mobile terminal, the screen of the above mobile terminal is in an on state or an off state.

[0045] Thus, when the screen of the mobile terminal is on or off, the content of the target object with permission can be displayed on the screen device. Thereby, the flexibility of displaying the content of the object on the mobile terminal on the screen device can be improved.

[0046] In some embodiments, an object list corresponding to the display mode of the above-mentioned mobile terminal is set. The above-mentioned execution entity may, in accordance with Figure 2 the process shown, determine whether the target object has the display permission to display content on the above-mentioned screen device. This process includes the following steps.

[0047] Step 201, obtain the object list set for the above-mentioned current display mode.

[0048] The above-mentioned object list includes at least one object on the above-mentioned mobile terminal. As an example, when the above-mentioned current display mode is the learning mode, the object list set for the above-mentioned current display mode may include at least one learning-type APP. As another example, when the above-mentioned current display mode is the meeting mode, the object list set for the above-mentioned current display mode may include at least one meeting-type APP.

[0049] In some scenarios, the object list set for the above-mentioned current display mode is locally stored in the mobile terminal. The above-mentioned execution entity may obtain the object list set for the above-mentioned current display mode from the local of the mobile terminal.

[0050] Step 202, determine whether the target object is included in the above-mentioned object list.

[0051] Step 203, in response to the target object being included in the above-mentioned object list, determine that the target object has the above-mentioned display permission.

[0052] In some embodiments, Figure 2 the process shown may further include step 204.

[0053] Step 204, in response to the target object not being included in the above-mentioned object list, determine that the target object does not have the above-mentioned display permission.

[0054] Thus, it can be determined whether the target object has the display permission to display content on the screen device according to whether the target object is included in the object list set for the above-mentioned current display mode. Thus, the content of the object included in the object list set for the above-mentioned current display mode can be displayed on the screen device.

[0055] In some embodiments, the above-mentioned object list includes a file list and / or an application list; the target object is a file stored on the above-mentioned mobile terminal or an installed application.

[0056] The file list may be a list for storing files (such as image files, text files, audio files, video files, etc.) stored on the above-mentioned mobile terminal. The application list may be a list for storing APPs installed on the above-mentioned mobile terminal.

[0057] It can be seen that the content of files or apps with display permissions in the above current display mode on the mobile terminal can be displayed on the screen device. The content of the file can be the content presented after the file is opened. The content of the app can be the content presented after the app is opened.

[0058] It can be understood that if the target object is a file stored on the mobile terminal, when determining whether the target object has display permissions according to the Figure 2 process shown, the above execution entity can obtain the file list set for the above current display mode and determine whether the target object is included in the file list. Similarly, if the target object is an app installed on the mobile terminal, when determining whether the target object has display permissions according to the Figure 2 process shown, the above execution entity can obtain the app list set for the above current display mode and determine whether the target object is included in the app list.

[0059] In some embodiments, the above object list is set by default on the above mobile terminal or is user-defined.

[0060] It can be seen that the user can pre-customize and set the object list of the above current display mode according to their actual needs. Thus, the user experience of displaying the content of the target object on the mobile terminal on the screen device can be improved.

[0061] In some embodiments, the above execution entity can also perform the following steps.

[0062] Specifically, before the above mobile terminal enters the free operation mode, in response to the screen of the above mobile terminal being in the on state, the content of the target object is displayed on the above mobile terminal.

[0063] It can be seen that before the mobile terminal enters the free operation mode, if the user performs a user operation on the target object (performed on the mobile terminal or on the screen device), the mobile terminal can display the content of the target object. In this case, if the target object has display permissions, both the mobile terminal and the screen device can display the content of the target object. At this time, the object content displayed on the mobile terminal and the screen device is the same.

[0064] In the above free operation mode, the above mobile terminal and the above screen device do not affect each other's responses to user operations. It can be understood that in the free operation mode, the user can perform user operations on the mobile terminal and the screen device respectively, and the mobile terminal and the screen device can display different contents by responding to the user operations.

[0065] In some embodiments, the above execution entity can also perform the following steps.

[0066] Specifically, after the above-mentioned mobile terminal enters the free operation mode, based on the user operation on any object on the above-mentioned mobile terminal, the content of the above-mentioned any object is displayed on the above-mentioned mobile terminal.

[0067] It can be seen that in the free operation mode, the screen device can display the content of the target object on the mobile terminal, and the mobile terminal can display the content of the above-mentioned any object. Thus, without affecting the user's viewing of the content of the object on the mobile terminal, the content of the target object on the mobile terminal is displayed on the screen device.

[0068] In some embodiments, the above-mentioned execution subject may execute the display control method of the present disclosure according to the Figure 3 process shown, and this process includes the following steps.

[0069] Step 301, determine the current display mode of the above-mentioned mobile terminal.

[0070] Step 302, receive user operation information.

[0071] Step 303, according to the above-mentioned current display mode, determine whether the target object has the display permission to display content on the above-mentioned screen device.

[0072] Step 304, in response to the target object having the above-mentioned display permission, control the above-mentioned mobile terminal to display the content of the target object on the above-mentioned screen device.

[0073] Steps 301 to 304 are similar to Figure 1 Steps 101 to 104 in the shown embodiment, and will not be elaborated here.

[0074] Step 305, after the above-mentioned mobile terminal enters the free operation mode, according to the object update operation of the user on the object list set for the above-mentioned current display mode, update the objects in the above-mentioned object list in real time.

[0075] The object update operation may include at least one of the following: adding an object on the mobile terminal to the object list; deleting an object included in the object list; replacing an object included in the object list. It can be understood that according to the user's object update operation, the target object can be added to the above-mentioned object list, or the target object can be deleted from the above-mentioned object list.

[0076] In some scenarios, after updating the object list, the mobile terminal may exit the free operation mode. At this time, the mobile terminal and the screen device may display the same content.

[0077] It can be seen that in the free operation mode, the user can update in real time the objects in the object list set for the current display mode, and this does not affect the user's execution of user operations on the target object and the display of the content of the target object on the screen device. Thus, the efficiency and flexibility of displaying the content of the target object on the screen device can be improved.

[0078] Further referring to Figure 4 , as an implementation of the methods shown in the above figures, the present disclosure provides some embodiments of a display control device.

[0086] In some embodiments, the display control device further includes a first display unit. Wherein, the first display unit is configured to, after the above mobile terminal enters the free operation mode, display the content of any object on the above mobile terminal based on the user's operation on any object on the above mobile terminal.

[0087] In some embodiments, the display control device further includes a second display unit. Wherein, the second display unit is configured to, before the above mobile terminal enters the free operation mode, in response to the screen of the above mobile terminal being in the on state, display the content of the target object on the above mobile terminal.

[0088] In some embodiments, the display control device further includes a rejection unit. Wherein, the rejection unit is configured to, in response to the target object not having the above display permission, reject the above mobile terminal from displaying the content of the target object on the above screen device.

[0089] In some embodiments, the user operation information is used to indicate the user operation performed by the user on the target object on the above mobile terminal or the above screen device.
