Description

Technical Field

[0001] This invention belongs to the field of display technology, and specifically relates to a method, device, display apparatus, and storage medium for controlling display content. Background Technology

[0002] Large-screen display panels, such as video wall displays, are frequently used in conference rooms and monitoring rooms. Traditional large-screen display panels typically play content according to the settings of the backend monitoring equipment. When switching content, the previous display must be closed, and the current user must find the relevant content before it is played. For example, in a conference room, the organizer needs to prepare materials for each participant in advance. During the meeting, each new speaker must close the previous speaker's materials and open the new presentation. For larger enterprises or organizations, the conference room can be connected to an office network system, but each new speaker still needs to close the previous speaker's interface and log in to their own account.

[0003] However, traditional large-screen display panels have a relatively simple way of displaying content, and the process of switching display content is cumbersome, resulting in a low level of intelligence and poor practicality. Summary of the Invention

[0053] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that, as long as there is no conflict, the various embodiments and features in the various embodiments of the present invention can be combined with each other, and the resulting technical solutions are all within the protection scope of the present invention.

[0054] Traditionally, large display panels (multi-panel screens (M*N)) formed by narrow-bezel LCD screens are increasingly used in scenarios such as indoor conferences, outdoor advertising, transportation hub advertising, and monitoring rooms. Each time content is displayed, either the current conventional method of transmitting the content via interface cables is used, or personnel are required to input the relevant content into a backend system and set the playback sequence. Therefore, the display methods of existing display panels are relatively limited.

[0055] When switching displayed content, the previous content usually needs to be turned off, and then the current user needs to find the content relevant to them before playing that content. This switching process is cumbersome, resulting in low intelligence and poor practicality for traditional large-screen display panels.

[0056] Therefore, in order to solve the above-mentioned technical problems, the present invention provides the following technical solutions.

[0057] Example 1

[0058] To address the aforementioned technical problems in the prior art, embodiments of the present invention provide a display panel and a method for controlling the displayed content based on the display panel, thereby improving the intelligence level and practicality of the display panel.

[0059] Figure 1 This is a schematic diagram of the display panel structure of the present invention, as shown below. Figure 1 As shown, the display panel in this embodiment may include a display screen 11 and a control device for displaying content (not shown in the figure). A communication module (not shown in the figure) may be set on the display screen 11. After the communication module is connected to the playback start terminal, it can perform data interaction with the playback start terminal.

[0060] In a specific implementation, the display screen 11 can be spliced ​​together from multiple display units 111 (only one display unit 111 is used as an example in the figure). In this way, a communication module can be set on each display unit 111. The position of the communication module on each display unit 111 can be the same. The user can select the required display unit 111 according to actual needs and control the display content of the required display unit 111.

[0061] Figure 2 for Figure 1 The cross-sectional diagram of area A shows that the physical seam of each display unit 111 is a crucial indicator of a video wall. To achieve this, the bezel width of video walls is generally small, typically around 0.8–2.0 mm. Due to the structural characteristics of video walls, it is impossible to directly design related structures on the sides to ensure this crucial indicator. Therefore, an external interface 112 for playback activation can be reserved on the side (bottom side or other side) of each display unit 111 as a communication module. In some embodiments, the external interface 112 for playback activation includes a biometric data acquisition device interface and / or a wireless device interface. This allows each display unit 111 to connect to a biometric data acquisition device and / or a wireless device, enabling users to control the display content of each display unit 111 via these devices.

[0062] In a specific implementation, the playback start-up external interface 112 can be sealed with independent external tape so that after each display unit 111 is assembled, the playback start-up external interface 112 can be enabled or the playback start-up external interface 112 of which display unit 111 can be enabled, depending on actual needs.

[0063] In one specific implementation, the playback initiator and its external interface 112 can be connected in a plug-and-play manner. The control device for displaying the content can automatically identify the type of the playback initiator and then automatically install the control program corresponding to that type.

[0064] Figure 3 for Figure 1 A schematic diagram of another type of communication module set in the display panel, such as... Figure 3 As shown, a wireless communication unit 113 can be installed on the back of each display unit 111 as a communication module. Specifically, a raised bulge structure can be provided on the back panel of each display unit 111, and the wireless communication unit 113 can be placed inside the raised bulge. The wireless signal passes through the reflective sheet 115 → optical film 116 → back panel 114, and is received on the front of the splicing screen. The wireless signal may include infrared remote control signals, wireless temperature signals, mechanical vibration wave signals, etc.

[0065] It should be noted that this embodiment uses a display screen 11 formed by splicing multiple display units 111 as an example to illustrate the technical solution of the present invention. However, in practical applications, it is not limited to this type of display screen 11, and it can also be a single display screen 11.

[0066] In a specific implementation, based on the above structure of the display panel, the controller for displaying content can execute the following methods for controlling the display content.

[0067] Figure 4 A flowchart illustrating an embodiment of the method for controlling the display content of the present invention, as shown below. Figure 4 As shown, the method for controlling the displayed content in this embodiment may specifically include the following steps:

[0068] 400. Receive display request information sent by the playback starter through the communication module on the display panel;

[0069] In one specific implementation, the user can send a display request to the communication module using the playback launcher. This display request may include the identity of the current requester and / or the identifier of the content to be displayed.

[0070] Specifically, the playback initiator may include biometric data collection devices, such as fingerprint scanners, iris scanners, image scanners, and voice scanners. These devices can collect the biometric information of the current requester as their identifier. The playback initiator may also include wireless devices, such as remote controls and card readers. The current requester can input the relevant information of the content they wish to display via these wireless devices as an identifier for the content to be displayed.

[0071] 401. Based on the display request information, determine the content to be displayed that corresponds to the display request information;

[0072] In a specific implementation process, if the received display request information includes an identifier of the content to be displayed, the content to be displayed can be determined directly based on the identifier of the content to be displayed.

[0073] In a specific implementation, if the request information includes the identity of the current requester, a pre-defined association between the identity and the displayed content can be established to determine the content to be displayed corresponding to the current requester's identity.

[0074] Specifically, different requesters' identity identifiers can be pre-entered, and each requester's identity identifier can be associated with one or more display contents. In this way, after receiving the current requester's identity identifier, the current requester's identity identifier is first verified, and after the verification is successful, one of the display contents associated with the current requester's identity identifier is selected as the content to be displayed.

[0075] 402. Obtain the display priority of the content to be displayed;

[0076] In a specific implementation, different requester priorities can be set for different requesters, and an association relationship between identity identifiers and requester priorities can be established. Thus, when the received display request information includes the current requester's identity identifier, the requester priority corresponding to the current requester's identity identifier can be determined based on the preset association relationship between identity identifiers and requester priorities. In this embodiment, different category priorities can also be set for different display content. This allows the category priority of the content to be displayed to be determined based on the preset correspondence between display content and category priorities.

[0077] After determining the requester priority corresponding to the current requester's identity and the category priority of the content to be displayed, the display priority of the content to be displayed can be determined based on these two factors. Specifically, if the category priority of the content to be displayed is higher than the preset priority, the category priority is used as the display priority; if the category priority is lower than or equal to the preset priority, the requester priority is used as the display priority.

[0078] In a specific implementation, if the category priority of the content to be displayed is higher than the preset priority, it indicates that the content to be displayed is relatively important. For example, in a monitoring room, sometimes when handling emergencies, it is necessary to immediately retrieve the content to be displayed from relevant monitoring points. If the category priority of this content is high, then the category priority of the content to be displayed can be used as its display priority. In this way, even if the requester's requester priority is low, the display priority of the content to be displayed can still be determined as a high display priority. Conversely, during normal monitoring, if two different requesters issue display requests, and the category priority of the content requested by both requesters is relatively low, then the requester priority of each requester can be used as the display priority of their respective content.

[0079] It should be noted that if the display request information only includes the identifier of the content to be displayed, then regardless of whether the category priority of the content to be displayed is higher than the preset priority, the category priority of the content to be displayed will be used as the display priority of the content to be displayed.

[0080] 403. Determine the playback control information of the content to be displayed based on the display priority of the content to be displayed;

[0081] In a specific implementation, it can detect whether there is currently displayed content; if there is currently displayed content, compare the display priority of the content to be displayed with the display priority of the currently displayed content; if the display priority of the content to be displayed is higher than the display priority of the currently displayed content, the playback control information is to switch the currently displayed content to the content to be displayed; if the display priority of the content to be displayed is lower than or equal to the display priority of the currently displayed content, the playback control information is to wait for the currently displayed content to finish playing before playing the content to be displayed.

[0082] In a specific implementation, if there is no currently displayed content, the playback control information is to switch the currently displayed content to the content to be displayed.

[0083] In a specific implementation, the display level of the content to be displayed can be set to three display priorities. The first display priority can interrupt the currently playing content corresponding to the second and third display priorities at will, and directly play the content currently displayed at the first display priority. The content to be displayed that is also at the first display priority must wait for the currently displayed content to finish playing before it can be played.

[0084] 404. Play the content to be displayed according to the determined playback control information.

[0085] The method for controlling the displayed content in this embodiment involves incorporating a communication module on the display panel. This module receives display request information sent by the playback initiation terminal. Based on the received display request information, it determines the content to be displayed corresponding to the request, further obtains the display priority of the content, and then determines playback control information based on that priority. This allows the content to be played according to the determined playback control information, avoiding the need for the user to manually close the previous displayed content before playing the desired content. Furthermore, it allows for the playback of content with different display priorities according to their respective priorities. By employing this technical solution, the intelligence and practicality of the display panel can be improved.

[0086] In a specific implementation, the technical solution of this invention can be applied in a conference room. Before the meeting, the relevant display content of each participant can be associated and stored with the corresponding participant's identity identifier. The requester priority of each participant is set according to their role, and the display content of each participant is categorized to obtain a category priority for each display content. During the meeting, before each participant needs to speak, they can send their identity identifier to the communication module through a fingerprint recognition device or other playback initiation terminal. This allows the display content corresponding to their identity identifier to be directly retrieved as the content to be displayed. The display priority of the content to be displayed can be determined based on their request priority and the category priority of the content to be displayed. If the current display content exists, the display priority is compared with the current display content, and the current display content is switched to the content to be displayed; alternatively, the content to be displayed can be played after the current display content has finished playing.

[0087] In a specific implementation, the technical solution of the present invention can be applied in a monitoring room. Under normal circumstances, the display panel displays the real-time content of each monitoring point in a split screen. When it is necessary to replay the content displayed in a certain period of time or the content displayed in a single monitoring point, a wireless device can receive a wireless signal, retrieve the content to be displayed corresponding to the identifier of the content to be displayed carried by the wireless signal, and determine the display priority of the content to be displayed according to the classification priority of the content to be displayed. If there is currently displayed content, the display priority is compared with that of the currently displayed content, and the currently displayed content is switched to the content to be displayed. Alternatively, the content to be displayed can be played after the currently displayed content has finished playing.

[0088] In a typical implementation, the monitoring and control computer for the display panel in the monitoring room is usually located in a temperature- and humidity-controlled safe room, which is far away and inconvenient to operate. However, in this embodiment, because a communication module is set on the display panel, the requester can send a request directly from the monitoring room to switch the displayed content, which further improves the practicality of the display panel.

[0089] It should be noted that the method of this embodiment can be executed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method of this embodiment, and the multiple devices will interact with each other to complete the method.

[0090] Example 2

[0091] To address the aforementioned technical problems in the prior art, embodiments of the present invention provide a control device for displaying content.

[0092] Figure 5 This is a schematic diagram of the structure of an embodiment of the control device for displaying the content of the present invention, as shown below. Figure 5 As shown, the control device for displaying content in this embodiment may include a receiving module 50, a first determining module 51, an acquiring module 52, a second determining module 53, and a control module 54.

[0093] The receiving module 50 is used to receive display request information sent by the playback initiation terminal through the communication module;

[0094] The first determining module 51 is used to determine the content to be displayed corresponding to the display request information based on the display request information;

[0095] In a specific implementation process, the displayed request information includes the identity identifier of the current requester and / or the identifier of the content to be displayed. The content to be displayed corresponding to the identity identifier of the current requester can be determined according to the preset association between the identity identifier and the displayed content, and / or the content to be displayed can be determined according to the identifier of the content to be displayed.

[0096] The acquisition module 52 is used to acquire the display priority of the content to be displayed;

[0097] In a specific implementation, if the displayed request information includes the current requester's identity identifier, the requester priority corresponding to the current requester's identity identifier can be determined based on a preset association between identity identifiers and requester priorities; and the category priority of the content to be displayed can be determined based on a preset correspondence between displayed content and category priorities; and the display priority of the content to be displayed can be determined based on the requester priority and the category priority of the content to be displayed. Specifically, if the category priority of the content to be displayed is higher than the preset priority, the category priority of the content to be displayed is used as the display priority of the content to be displayed; if the category priority of the content to be displayed is lower than or equal to the preset priority, the requester priority is used as the display priority of the content to be displayed.

[0098] If the display request information only includes the identifier of the content to be displayed, the category priority of the content to be displayed can be determined according to the preset correspondence between display content and category priority, and the category priority of the content to be displayed can be used as the display priority of the content to be displayed.

[0099] The second determining module 53 is used to determine the playback control information of the content to be displayed based on the display priority of the content to be displayed;

[0100] Specifically, the system can detect whether currently displayed content exists. If it does, it compares the display priority of the content to be displayed with that of the currently displayed content. If the display priority of the content to be displayed is higher than that of the currently displayed content, the playback control information switches the currently displayed content to the content to be displayed. If the display priority of the content to be displayed is lower than or equal to that of the currently displayed content, the playback control information waits for the currently displayed content to finish playing before playing the content to be displayed. If no currently displayed content exists, the playback control information switches the currently displayed content to the content to be displayed.

[0101] The control module 54 is used to play the content to be displayed according to the playback control information determined by the second determining module 53.
