Well-known and/or repeated functions and structures have not been described in detail so as not to obscure the present disclosure with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
In the prior art, when receiving a wireless connection signal sent by a device such as a conference machine to request information sharing, an electronic device cannot automatically make a corresponding response, and needs a user to perform a personal operation to complete the sharing, which brings inconvenience to the user.
To solve the above problem, as shown in fig. 1, an embodiment of the present application provides a display control method, including:
receiving a wireless connection signal;
determining whether the wireless connection signal meets a first preset condition, and if so, switching the display mode of the current screen from the first display mode to a second display mode;
wherein the second display mode is an extended display mode.
In the embodiment of the present application, by detecting whether the wireless connection signal satisfies a first preset condition, for example, detecting whether a sender of the wireless connection signal is a conference machine or a designated server, and then, for example, detecting whether the wireless connection signal is a specific signal for providing a communication channel for conference information sharing, or setting a wireless connection signal list in advance, detecting whether the received wireless connection signal is located in the wireless connection signal list, and the like, if it is detected that the received wireless connection signal satisfies the first preset condition, the system automatically switches a display mode of a current screen, for example, a normal display mode, to an extended display mode different from the normal display mode. The extended display mode can be used to implement functions such as sharing conference content or remotely sending content to be shared. That is, for example, when a user wants to establish a wireless communication connection with an electronic device of the user to share some content on the electronic device during a meeting, the user can communicate with the meeting machine and switch the current display mode of the electronic device without any manual operation on the electronic device, thereby greatly simplifying the use procedure of the user, saving the meeting time and improving the meeting efficiency.
Further, as shown in fig. 2, the second display mode in this embodiment is specifically:
and displaying an extended display window, wherein the content displayed by the extended display window is the same as or at least partially different from the content displayed by the current screen.
When the system determines that the wireless connection signal meets the first preset condition, the system switches the display mode to the second display mode, and then displays an extended display window on the screen, wherein the extended display window can display the same content as the content displayed on the entity screen of the electronic device, and can display the content which is completely different from the content displayed on the entity screen, or only partially different from the content displayed on the entity screen. For example, the extended display window currently displays the ppt content that the user wants to share, while the entity screen currently displays the ppt that the user has notes for explanation; if yes, displaying a sales data graph of the first half year of a certain product to be shared by the user in the expansion display window, and displaying the content of a certain webpage currently displayed on the entity screen; or the content displayed by the extended display window is consistent with the content displayed by the entity screen and synchronously changes, and the like.
When a user wants to share a screen, for example, the private content can be protected by sharing the content in the extended window, and the sharing function is not affected.
Further, with continuing reference to fig. 2, to achieve the above technical effect, the method in the embodiment of the present application further includes:
generating an identification instruction for enabling an operating system to identify the extended display window as a newly added display while displaying the extended display window; and
and displaying the target content in the extended display window according to the user instruction, and sharing and/or remotely transmitting the target content according to the user instruction.
Specifically, when the screen displays the extended display window, an identification instruction is generated, and the instruction is used for enabling the operating system to identify the extended display window as the new display. That is, the extended display window is an extended independent screen, which is independent from the physical screen of the electronic device, and is equivalent to the extended display in the prior art, and can realize the same function as the extended display. When the system is applied, the system can display the target content selected by the user in the expansion display window according to the user instruction, for example, the content to be shared by the user, and meanwhile, the system can also share and/or remotely send the target content according to the user instruction.
Further, the wireless connection signal in the embodiments of the present application includes one or more of a wireless communication signal, a wireless connection signal with different predefinitions. For example, the wireless connection signal sent by the conference machine to the electronic device of the user includes a wireless communication signal, and the system may determine whether the current wireless network environment supports establishing a stable communication relationship with the conference machine by detecting the wireless communication signal, and if so, may determine that a communication connection can be established. At this time, the system can detect whether other wireless connection signals are included, and if not, the system can directly switch the display mode; if there is, for example, one signal with predefined wireless connection, the system may detect the signal, determine whether it satisfies the first predetermined condition, and if so, switch the display mode.
Further, as shown in fig. 3, when the wireless connection signal is detected to have a predefined wireless connection signal, determining whether the wireless connection signal satisfies the first preset condition specifically includes:
determining predefined information of the wireless connection signal;
it is determined whether the predefined information satisfies a first preset condition.
For example, when receiving a wireless connection signal, the system first identifies the wireless connection signal, determines whether the wireless connection signal has predefined information, if so, acquires the predefined information and performs identification detection on the predefined information to determine whether the wireless connection signal satisfies a first preset condition, and if so, the system switches the display mode in response to the signal. And if not, no response may be made. The first predetermined condition may be a list including a plurality of identity information, and the predefined information includes identity information of a sender of the wireless connection signal, and the system may determine whether the identity information of the sender of the wireless connection signal is in the list by detecting whether the identity information of the sender of the wireless connection signal satisfies the first predetermined condition. For another example, the first preset condition is a list containing multiple kinds of specific information or only one kind of specific information, for example, when a large number of users use the conference machine to carry out a conference, all participants establish communication connection with the conference machine, but the lecturer in each conference link in the conference can only have one person at a time, and at this time, the conference machine will periodically switch to carry out communication connection with different participants by using another network interface according to the lecture sequence of the lecturer in each link, so as to obtain the lecture content of the lecturer in real time, and synchronously send the lecture content to other participants. In order to realize the switching, the conference machine can send a wireless connection signal with specific information to the speaker, the specific information indicates that the user is the speaker, and the electronic equipment of the user recognizes that the signal meets the first preset condition through detection after receiving the wireless connection signal, so that the display mode is adjusted to be changed into the extended display mode, and the sharing of the conference content is realized. Alternatively, the first preset condition may be a combination of the above two conditions, or a combination of more detection conditions, for example, the system may switch the display mode only when it is determined whether the current network environment satisfies the condition, whether the identity of the sender of the wireless connection signal satisfies the condition, and whether there is specific information.
Based on the above embodiment, as shown in fig. 4, when the system currently receives a plurality of wireless connection signals, the displaying of the extended display window specifically includes:
determining a wireless connection signal which meets a first preset condition in the plurality of wireless connection signals;
and displaying at least one expansion display window on the screen according to the wireless connection signal meeting the first preset condition. That is, the signals that may satisfy the first predetermined condition among the plurality of wireless connection signals are not unique, and when it is detected that the plurality of wireless connection signals all satisfy the first predetermined condition, the plurality of extended display windows may be displayed. For example, a plurality of wireless connection signals (each of which is assumed to have predefined information) that meet the condition may be divided into categories of the predefined information, a plurality of extended display windows may be displayed according to the number of different categories, and the like.
Further, in this embodiment, when the system monitors that a plurality of wireless connection signals meet the first preset condition:
determining identity information of a sender of a wireless connection signal meeting a first preset condition;
and determining whether the identity information meets a second preset condition, and if so, displaying an extended display window which has a unique matching relation with the identity information.
For example, the conference machines in multiple conference rooms simultaneously send a wireless connection signal to a presenter, and the system may determine a second preset condition according to conference participants and conference positions included in a current conference of the presenter, conference contents (assuming that the system can obtain schedule information of a user and determine the information from the schedule information), and the like, that is, the preset condition may include information about which conferences the user needs to participate in at present, which conferences have the same content, and which conference machines need to establish communication connection with, and the like.

wherein the second display mode is an extended display mode.
In the embodiment of the application, by detecting whether the wireless connection signal satisfies a first preset condition, for example, detecting whether a sender of the wireless connection signal is a conference machine or a designated server, and then, for example, detecting whether the wireless connection signal is a specific signal for providing a communication channel for conference information sharing, or setting a wireless connection signal list in advance, detecting whether the received wireless connection signal is located in the wireless connection signal list, and the like, if it is detected that the received wireless connection signal satisfies the first preset condition, the processor automatically switches a display mode of a current screen, such as a normal display mode, to an extended display mode different from the normal display mode. The extended display mode can be used to implement functions such as sharing conference content or remotely sending content to be shared. That is, for example, when a user wants to establish a wireless communication connection with an electronic device of the user to share some content on the electronic device during a conference, the user can communicate with the conference machine and switch the current display mode of the electronic device without any manual operation on the electronic device, which greatly simplifies the use flow of the user, saves the conference time and improves the conference efficiency.
Further, the second display mode in this embodiment is specifically:
and displaying an extended display window, wherein the content displayed by the extended display window is the same as or at least partially different from the content displayed by the current screen.
When the processor determines that the wireless connection signal meets the first preset condition, and the display mode is switched to the second display mode, the processor displays an extended display window on the screen, and the extended display window can display the same content as the content displayed on the entity screen of the electronic device, or can display the content completely different from the content displayed on the entity screen, or only partially different from the content displayed on the entity screen. For example, the extended display window currently displays the ppt content that the user wants to share, and the entity screen currently displays the ppt that the user has notes for explanation; if yes, displaying a sales data graph of the first half year of a certain product to be shared by the user in the expansion display window, and displaying the content of a certain webpage currently displayed on the entity screen; or the content displayed by the extended display window is consistent with the content displayed by the entity screen and synchronously changes, and the like.
When a user wants to share a screen, for example, the private content can be protected by sharing the content in the extended window, and the sharing function is not affected.
Further, to achieve the above technical effects, in the electronic device in the embodiment of the present application:

and displaying the target content in the extended display window according to the user instruction, and sharing and/or remotely transmitting the target content according to the user instruction.
Specifically, when the screen displays the extended display window, an identification instruction is generated, and the instruction is used for enabling the operating system to identify the extended display window as the new display. That is, the extended display window is an extended independent screen, which is independent from the physical screen of the electronic device, and is equivalent to the extended display in the prior art, and can realize the same function as the extended display. When the method is used, the processor can display the target content selected by the user in the expansion display window according to the user instruction, for example, the content to be shared by the user, and meanwhile, the processor can share and/or remotely send the target content according to the user instruction.
Further, the wireless connection signal in the embodiments of the present application includes one or more of a wireless communication signal, a wireless connection signal with different predefinitions. For example, the wireless connection signal sent by the conference machine to the electronic device of the user includes a wireless communication signal, and the processor may determine whether the current wireless network environment supports establishing a stable communication relationship with the conference machine by detecting the wireless communication signal, and if so, may determine that a communication connection can be established. At this time, the processor can detect whether other wireless connection signals are included, and if not, the processor can directly switch the display mode; if there is, for example, one signal with predefined wireless connection, the processor may detect the signal, determine whether the signal satisfies a first preset condition, and if so, switch the display mode.
Further, when the processor detects that the wireless connection signal is a signal with a predefined wireless connection, determining whether the wireless connection signal satisfies a first preset condition specifically includes:

For example, the processor first identifies the received wireless connection signal, determines whether the wireless connection signal has predefined information, if so, acquires the predefined information and performs identification detection on the predefined information to determine whether the predefined information meets a first preset condition, and if so, the processor switches the display mode in response to the signal. And if not, no response may be made. The first predetermined condition may be a list including a plurality of identity information, and the predefined information includes identity information of a sender of the wireless connection signal, and the processor may determine whether the identity information of the sender of the wireless connection signal is in the list by detecting whether the identity information of the sender of the wireless connection signal is in the list. For another example, the first preset condition is a list containing multiple kinds of specific information or only one kind of specific information, for example, when a large number of users use the conference machine to carry out a conference, all participants establish communication connection with the conference machine, but the lecturer in each conference link in the conference can only have one person at a time, and at this time, the conference machine will periodically switch to carry out communication connection with different participants by using another network interface according to the lecture sequence of the lecturer in each link, so as to obtain the lecture content of the lecturer in real time, and synchronously send the lecture content to other participants.
