Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present application is mainly directed to a sound and picture synchronization process of a display device having a dual-system and dual-display structure, that is, a display device having a first controller (a first hardware system), a second controller (a second hardware system), a first display, and a second display, and the following first describes details of structures, functions, implementation manners, and the like of the display device having the dual-system hardware structure.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

In various embodiments of the present application, a hardware system may also be referred to as a motherboard (or chip).

A schematic diagram of an operational scenario between a display device and a control apparatus according to some embodiments is illustrated in fig. 1. As shown in fig. 1, a user may operate the display apparatus 200 through the control device 100.

The control device 100 may be a remote controller 100A, which can communicate with the display device 200 through an infrared protocol communication, a bluetooth protocol communication, a ZigBee (ZigBee) protocol communication, or other short-range communication, and is used to control the display device 200 in a wireless or other wired manner. The user may input a user instruction through a key on the remote controller 100A, voice input, control panel input, or the like to control the display apparatus 200. Such as: the user can input a corresponding control command through a volume up/down key, a channel control key, up/down/left/right movement keys, a voice input key, a menu key, a power on/off key, etc. on the remote controller 100A to control the functions of the display device 200.

The control device 100 may also be an intelligent device, such as a mobile terminal 100B, a tablet computer, a notebook computer, and the like, which may communicate with the display device 200 through a Local Area Network (LAN), a Wide Area Network (WAN), a Wireless Local Area Network (WLAN), or other networks, and implement control of the display device 200 through an application program corresponding to the display device 200. For example, the display device 200 is controlled using an application program running on the smart device. The application may provide various controls to the User through an intuitive User Interface (UI) on a screen associated with the smart device.

For example, the mobile terminal 100B and the display device 200 may each have a software application installed thereon, so that connection communication between the two can be realized through a network communication protocol, and the purpose of one-to-one control operation and data communication can be further realized. Such as: a control instruction protocol can be established between the mobile terminal 100B and the display device 200, a remote control keyboard is synchronized to the mobile terminal 100B, and the function of controlling the display device 200 is realized by controlling a user interface on the mobile terminal 100B; the audio and video content displayed on the mobile terminal 100B may also be transmitted to the display device 200, so as to implement a synchronous display function.

As shown in fig. 1, the display apparatus 200 may also perform data communication with the server 300 through various communication means. In various embodiments of the present application, the display device 200 may be allowed to be in a wired or wireless communication connection with the server 300 via a local area network, a wireless local area network, or other network. The server 300 may provide various contents and interactions to the display apparatus 200.

Illustratively, the display device 200 receives software program updates, or accesses a remotely stored digital media library by sending and receiving information, and Electronic Program Guide (EPG) interactions. The servers 300 may be a group or groups, and may be one or more types of servers.

For example, the first display 201 may be used for screen display of conventional television programs, and the second display 202 may be used for screen display of auxiliary information such as notification type messages, voice assistants, and the like.

Alternatively, the content displayed by the first display 201 and the content displayed by the second display 202 may be independent of each other and not affected by each other. For example, when the first display 201 plays a television program, the second display 202 may display information such as time, weather, temperature, reminder messages, and the like, which are not related to the television program.

Optionally, there may also be an association between the content displayed by the first display 201 and the content displayed by the second display 202. For example, when the first display 201 plays a main screen of a video chat, the second display 202 may display information such as an avatar, a chat duration, and the like of a user currently accessing the video chat.

Optionally, part or all of the content displayed by the second display 202 may be adjusted to be displayed by the first display 201. For example, the information such as time, weather, temperature, reminder message, etc. displayed on the first display 201 may be adjusted to be displayed on the first display 201, while other information is displayed on the second display 202.

In addition, the first display 201 displays the multi-party interactive picture while displaying the traditional television program picture, and the multi-party interactive picture does not block the traditional television program picture. The display mode of the traditional television program picture and the multi-party interactive picture is not limited by the application. For example, the position and the size of the traditional television program picture and the multi-party interactive picture can be set according to the priority of the traditional television program picture and the multi-party interactive picture.

Taking the example that the priority of the traditional television program picture is higher than that of the multi-party interactive picture, the area of the traditional television program picture is larger than that of the multi-party interactive picture, and the multi-party interactive picture can be positioned at one side of the traditional television program picture and can also be arranged at one corner of the multi-party interactive picture in a floating manner.

The display device 200, in one aspect, may be a liquid crystal display, an oled (organic Light emitting diode) display, a projection display device; on the other hand, the display device can be a display system consisting of an intelligent television or a display and a set-top box. The specific display device type, size, resolution, etc. are not limiting, and those skilled in the art will appreciate that the display device 200 may be modified in performance and configuration as desired.

The display apparatus 200 may additionally provide an intelligent network tv function that provides a computer support function in addition to the broadcast receiving tv function. Examples include a web tv, a smart tv, an Internet Protocol Tv (IPTV), and the like. In some embodiments, the display device may not have a broadcast receiving television function.

Specifically, the picture shot by the camera can be displayed on the display device in a full screen mode, a half screen mode or any optional area.

As an optional connection mode, the camera is connected with the rear shell of the display device through the connecting plate, and is fixedly installed in the middle of the upper side of the rear shell of the display device.

As another optional connection mode, the camera is connected to the rear shell of the display device through a connection board or another conceivable connector, the camera is capable of lifting and descending, a lifting motor is installed on the connector, when a user wants to use the camera or an application program wants to use the camera, the camera is lifted out of the display device, and when the camera is not needed, the camera can be embedded into the rear shell, so that the camera is protected from being damaged, and privacy safety of the user is protected.

As an embodiment, the camera adopted in the present application may have 1600 ten thousand pixels, so as to achieve the purpose of ultra high definition display. In actual use, cameras higher or lower than 1600 ten thousand pixels may also be used.

After the camera is installed on the display device, the contents displayed by different application scenes of the display device can be fused in various different modes, so that the function which cannot be realized by the traditional display device is achieved.

Illustratively, a user may conduct a video chat with at least one other user while watching a video program. The presentation of the video program may be as a background frame over which a window for video chat is displayed. The function is called 'chat while watching'.

Optionally, in a scene of "chat while watching", at least one video chat is performed across terminals while watching a live video or a network video.

In another example, a user can conduct a video chat with at least one other user while entering the educational application for learning. For example, a student may interact remotely with a teacher while learning content in an educational application. Vividly, this function can be called "chatting while learning".

In another example, a user conducts a video chat with a player entering a card game while playing the game. For example, a player may enable remote interaction with other players when entering a gaming application to participate in a game. Figuratively, this function may be referred to as "watch while playing".

Optionally, the game scene is fused with the video picture, the portrait in the video picture is scratched and displayed in the game picture, and the user experience is improved.

Optionally, in the motion sensing game (such as ball hitting, boxing, running and dancing), the human posture and motion, limb detection and tracking and human skeleton key point data detection are obtained through the camera, and then the human posture and motion, the limb detection and tracking and the human skeleton key point data detection are fused with the animation in the game, so that the game of scenes such as sports and dancing is realized.

In another example, a user may interact with at least one other user in a karaoke application in video and voice. Vividly, this function can be called "sing while watching". Optionally, when at least one user enters the application in a chat scenario, multiple users may jointly complete recording of a song.

The live television application program can provide live television through different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

A video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

The media center application program can provide various applications for playing multimedia contents. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

The application program center can provide and store various application programs. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on a display device. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

Since the second controller 310 and the first controller 210 may have independent operating systems installed therein, there are two independent but interrelated subsystems in the display apparatus 200. For example, Android (Android) and various APPs may be independently installed on the second controller 310 and the first controller 210, and may all realize a certain function, and the second controller 310 and the first controller 210 cooperate to realize a certain function.

A schematic diagram of a user interface in a display device 200 according to some embodiments is illustrated in fig. 9. As shown in fig. 9, the user interface includes a first diagram display area 2011 and a second diagram display area 2021. The first diagram display area 2011 and the second diagram display area 2021 have substantially the same function, and only the first diagram display area 2011 is described in an important manner below. Illustratively, among other things, the first view display 2011 includes layouts for one or more different items. And a selector indicating that the item is selected is also included in the user interface, and a position of the selector is movable by a user input to change a selection of a different item.

A "user interface" is a media interface for interaction and information exchange between an application or operating system and a user that enables the conversion of the internal form of information to a form acceptable to the user. A common presentation form of a user interface is a Graphical User Interface (GUI), which refers to a user interface related to computer operations and displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in the display screen of the electronic device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

In some embodiments, the first view display area 2011 is a scalable view display. "scalable" may mean that the first view display area 2011 is scalable in size or proportion on the screen, or that the items in the view display 201 are scalable in size or proportion on the screen.

"item" refers to a visual object displayed in a view display area of a user interface in the display device 200 to represent corresponding content, such as icons, thumbnails, video clips, and the like. For example: the items may represent movies, image content or video clips of a television show, audio content of music, applications, or other user access content history information.

Further, the item may represent an interface or a collection of interfaces on which the display device 200 is connected to an external device, or may represent a name of an external device connected to the display device, or the like. Such as: a signal source input Interface set, or a High Definition Multimedia Interface (HDMI), a USB Interface, a PC terminal Interface, and the like.

It should be noted that: the view display area may present Video chat project content or application layer project content (e.g., web page Video, Video On Demand (VOD) presentations, application screens, etc.).

A "selector" is used to indicate where any item has been selected, such as a cursor or a focus object. Positioning the selection information input according to an icon or menu position touched by the user in the display 200 may cause movement of a focus object displayed in the display device 200 to select a control item, one or more of which may be selected or controlled.

The focus object refers to an object that moves between items according to user input. Illustratively, the focus object position is implemented or identified by drawing a thick line through the item edge. In other embodiments, the focus form is not limited to an example, and may be a form such as a cursor that is recognizable by the user, either tangible or intangible, such as in the form of a 3D deformation of the item, or may change the identification of the border lines, size, color, transparency, and outline and/or font of the text or image of the item in focus.

The event transmission system 2914, which may monitor user input for each predefined event or sub-event heard, provides control identifying the event or sub-event directly or indirectly to the interface layout management module 2913.

The interface layout management module 2913 is configured to monitor the state of the user interface (including the position and/or size of the view partition, the item, the focus or the cursor object, the change process, and the like), and according to the event or the sub-event, may perform a modification on the layout of the size and position, the hierarchy, and the like of the view display area, and/or adjust or modify the layout of the size or/and position, the number, the type, the content, and the like of the layout of various items in the view display area. In some embodiments, the layout is modified and adjusted, including displaying or not displaying the view sections or the content of the items in the view sections on the screen.

And a user input interface for transmitting an input signal of a user to the controller or transmitting a signal output from the controller to the user. For example, the control device (e.g., a mobile terminal or a remote controller) may send an input signal, such as a power switch signal, a channel selection signal, a volume adjustment signal, etc., input by a user to the user input interface, and then the input signal is forwarded to the controller by the user input interface; alternatively, the control device may receive an output signal such as audio, video, or data output from the user input interface via the controller, and display the received output signal or output the received output signal in audio or vibration form.

In some embodiments, a user may input a user command on a Graphical User Interface (GUI) displayed on the display 200, and the user input interface receives the user input command through the Graphical User Interface (GUI). Alternatively, the user may input the user command by inputting a specific sound or gesture, and the user input interface receives the user input command by recognizing the sound or gesture through the sensor.

In some embodiments, a plurality of components are configured in the display device, so that the display device presents rich page effects and use experience. For example, a fan is arranged in the display device to perform a heat dissipation operation when the display device is in operation; and the color wheel enables the page of the display device to present continuous color change.

When the display device is operated for a long time, various components are prone to faults, such as heat dissipation faults, fan locking, display faults and the like (color wheel errors). In order to facilitate a user to know which component fails in time when the display device fails so as to repair the component as soon as possible, the corresponding information of the failed component needs to be displayed to prompt the user.

According to the display device provided by the embodiment of the invention, the display configured by the display device is used for displaying the fault information, so that a user can know that the display device has a fault and know the fault type in time.

In some embodiments, as the user's demand for the application experience is higher, the requirements for various performance indexes of the operating system of the display device are also higher, and in order to provide rich display content, it is also possible to provide a dual system and a dual screen on the display device. The dual system comprises a first controller and a second controller, wherein the two controllers are both configured with independent application programs for running, and the first controller and the second controller can realize connection, communication and power supply through a plurality of interfaces of different types. The double screens comprise a first display and a second display, and the second display is used as a small screen and is used for showing the social ability and information prompt of the user; the first display is used as a large screen and used for displaying the display content of the corresponding application.

When the fault warning information generated when the display device is in fault is displayed on the display, the method can be applied to the display device with a single system and a single screen, and can also be applied to the display device with a double system and double screens shown in fig. 10. The invention takes the application of the display method of the fault warning information to the double-system double-screen display equipment as an example, for example, the display method is applied to a double-screen laser television for explanation.

A block diagram of a display device according to some embodiments is illustrated in fig. 10. Referring to fig. 10, an embodiment of the present invention provides a display device 200, including: a first display 201 (identical to the first display 280 in fig. 5), a second display 202 (identical to the second display 380 in fig. 5), a first controller 210, and a second controller 310. Each controller runs an independent Android system, that is, a first hardware system runs on the first controller 210, a second hardware system runs on the second controller 310, the first hardware system is a master system, and the second hardware system is a slave system. The first controller 210 (first hardware system) and the second controller 310 (second hardware system) are connected via an HDMI interface, and may also be connected via a data path, so as to implement data transmission between the two systems.

The first display 201 is connected to the first controller 210 in a communication manner, and is used for displaying the display content of each application configured in the first controller 204 and providing the main television service; the second display 202 is connected to the second controller 310 and is used for showing social ability and auxiliary information prompts to the user, in this embodiment, the fault warning information generated when the display device has a fault is controlled by the second controller 310 to be displayed in the second display 202.

An interaction block diagram of a first controller with a second controller according to some embodiments is illustrated in fig. 11; FIG. 12 is a flow chart illustrating a method of displaying fault alarm information according to some embodiments; a data flow diagram illustrating a method of displaying fault alarm information in accordance with some embodiments is illustrated in fig. 13. Referring to fig. 11, 12 and 13, in displaying the fault warning information in the second display, the first controller of the display device according to the embodiment of the present invention is configured to perform the following steps:

and S1, monitoring whether the display device is in a fault state.

In order to display the fault warning information in time, the fault monitoring module is required to monitor the fault of the display device. In some embodiments, the fault monitoring module may be an hstvos process configured in the first controller, and perform real-time monitoring on a fault state according to the hstvos process, and perform a subsequent process of analyzing a specific fault type and generating fault alarm information after a fault occurs.

When a user starts the display device, the fault monitoring module is initialized, namely, the hstvos process is automatically operated after being initialized. Specifically, a state monitoring thread and a display system monitoring thread run in the hstvos process, the state monitoring thread monitors the fault state, and the display system monitoring thread analyzes the specific fault type and generates fault alarm information.

In some embodiments, the first controller, in performing the monitoring whether the display device is in the failure state, is further configured to perform the steps of:

and step 11, when the display device is started, a state monitoring thread is started, and the state monitoring thread is used for monitoring the GPIO level value and the current state of the display panel.

And step 12, monitoring whether the display device is in a fault state or not according to the GPIO level value and the current state of the display panel.

And when the display device is started and executes a starting initialization process, the state monitoring thread and the display system monitoring thread are started, and the state monitoring thread reads the GPIO level value of the display device in operation and the current state of the display panel at intervals. The GPIO level value is used for representing a voltage value of the display device during operation, the display panel is a circuit board which is configured in the first controller and used for realizing display content, and the current state of the display panel is a state whether a display effect is normal or not.

And judging whether the display device is in a fault state or not according to the GPIO level value and the current state of the display panel. For example, if the GPIO level value does not satisfy the level threshold, or the current state of the display panel is an abnormal state, it may be determined that the display device is in a faulty state, and otherwise, it is not in a faulty state.

And if the state monitoring thread monitors that the display equipment is in a fault state, setting a corresponding fault flag bit. And meanwhile, circularly detecting the monitoring thread of the display system, if the monitoring thread of the display system detects a fault zone bit, determining that the display equipment has a fault, and starting to execute the steps of subsequent fault type analysis and fault alarm information.

And S2, when the display equipment is in a fault state, acquiring a first fault code written in a first register, wherein the first register is used for writing a fault code of which the fault type is corresponding to the fault subclass.

The first controller is internally provided with a register for writing a corresponding fault code when in fault, and if the display equipment is in a fault state, the register writes the fault code corresponding to the fault. And when the display equipment is in a fault state, namely after the monitoring thread of the display system detects a fault flag bit, acquiring a corresponding fault code written in the register.

The fault codes written by different registers represent different fault types, and the fault types are divided into a fault major class and a fault minor class, for example, the fault codes corresponding to the fault major class are written by a register of 0x08, and the fault codes corresponding to the fault minor class are written by a register of 0x 12. The failure category refers to the category of failures, such as heat dissipation failure, fan failure, display failure (color wheel error), and the like; the fault subclass refers to subclasses under a certain fault class with faults, such as a fault of the fan 1, a fault of the color wheel 2, and the like. The fault broad class includes a plurality of fault sub-classes.

The accuracy of the fault types analyzed by the fault codes written in different registers is different. If the fault code written in the register of 0x08 is read, only the fault class to which the fault belongs can be analyzed; if the fault code written by the 0x12 register is read, the fault subclass under the fault subclass can be analyzed.

For example, if a fan fails, if the fault code written in the register 0x08 is read, only the fault category "fan failure" can be analyzed. And a plurality of fans may be arranged in the display device, and only the fan failure is determined, which fan fails cannot be accurately determined, and at this time, if the failure code written in the 0x12 register is read, the failure subclass of "fan 1 failure" can be analyzed, so as to specifically determine that the first fan fails.

In some embodiments, to ensure that which particular device fails can be accurately determined, the register 0x12 is used as the first register, and when the display device is determined to fail, the first failure code written in the first register is read.

S3, determining a target fault subclass corresponding to the fault state of the display device based on the first fault code and a first fault type comparison table, wherein the first fault type comparison table comprises a plurality of fault codes and fault subclasses corresponding to one.

Each component in the display device is set with a corresponding fault code when the component fails, for example, if the fan fails, the fault code may be 0x 01; if the color wheel is not rotating, the fault code may be 0x 03. And establishing a fault type comparison table for each fault code and fault type so as to be convenient for the one-to-one correspondence of the fault code and the fault type according to the read fault code. And determining the fault type corresponding to the fault of the current display equipment by referring to the fault type comparison table. Different registers correspond to different fault type comparison tables.

In some embodiments, when the first register adopts a register 0x12, the read fault code is a first fault code, and at this time, a first fault type comparison table corresponding to the first register is obtained, where the first fault type comparison table includes a plurality of first fault codes and fault subclasses that are in one-to-one correspondence. And comparing the first fault code with the first fault type comparison table to determine a target fault subclass corresponding to the first fault code, wherein the target fault subclass is the fault type corresponding to the current display equipment when the display equipment has faults.

For example, if a fan fails, the target failure subclass is "Fan 1 Fault"; if the display is faulty, the target fault subclass is "color wheel 2 fault".

And S4, generating fault alarm information based on the first fault code and the target fault subclass.

And when the user can know the type of the fault of the display equipment in time, fault warning information can be generated according to the first fault code and the target fault subclass, wherein the fault warning information is the content displayed in the display.

A flow diagram of a method of generating fault alarm information according to some embodiments is illustrated in fig. 14. In some embodiments, referring to fig. 14, the first controller, in performing generating the fault warning information based on the first fault code and the target fault subclass, is further configured to perform the steps of:

and S41, generating a fault alarm text according to the target fault subclass and the first fault code.

S42, acquiring a target fault state and a target message type corresponding to the display device in the fault state, wherein the target fault state is used for representing whether the display device is in the fault state, and the target message type is used for representing the category of the message.

And S43, generating fault alarm information according to the type of the target message, the fault state of the target and the sequence of the fault alarm text.

After determining the target fault subclass and the first fault code, the first controller needs to process the target fault subclass and the first fault code into information which can be displayed in the second display. Therefore, a fault warning text is generated according to the target fault subclass and the first fault code.

When the first controller sends a message to the second controller, the second controller needs to execute different processing procedures according to different messages. Thus, the target message type may be carried when the first controller sends a message to the second controller. The target message type is used for representing the type of the message, for example, if the currently sent message is a text, the message type is a text type; if the sent message is related information of the fault, the message type is the fault type; and if the sent message is the control requirement information, the message type is the requirement type.

When the first controller judges that the display device has a fault, the first controller sends a message to the second controller, and the message can be identified as a fault type, namely the target message type is the fault type.

When the first controller sends a message to the second controller, it is further required to determine the fault state of the current display device, that is, whether the current display device is in the fault state, so as to control the second display to perform the operation of displaying or canceling the display.

In order to facilitate the display of the second display, when the first controller sends a message to the second controller, fault warning information in a json format is generated according to the type of a target message, the target fault state and the sequence of a fault warning text. At this time, when the second display is displaying, the displayed content may be a malfunction alert text.

In other embodiments, if the type of the fault occurring on the display device is a relatively simple fault, and the user can repair the fault by himself, the first controller may also provide prompt information of the repair means while generating a fault alarm text.

Specifically, the first controller is executing generating a fault alarm text according to the target fault subclass and the first fault code, and is further configured to execute the following steps:

and 411, determining the prompt information of the repair means for repairing the fault corresponding to the target fault subclass according to the target fault subclass.

And step 412, generating a fault alarm text according to the target fault subclass, the first fault code and the repair means prompt message.

After the target fault subclass is determined, the first controller can judge whether the target fault subclass is a simple fault or a complex fault, and if the target fault subclass is the simple fault, the first controller determines repair means prompt information to prompt a user that the fault corresponding to the target fault subclass can be repaired by the user.

And then the first controller generates a fault warning text according to the target fault subclass, the first fault code and the repair means prompt message, and the content displayed in the second display comprises the first fault code and the repair means prompt message.

And S5, sending the fault warning information to the second controller, and sending the fault warning information to the second display by the second controller for displaying.

And after the first controller generates the fault warning information, the first controller sends the fault warning information to the second controller, so that the second controller sends the fault warning information to the second display and displays the fault warning information. The second display displays the fault warning information, so that a user can know the fault type of the display equipment at any time. And after the user sees the fault warning information displayed in the second display, the specific fault type of the current display equipment can be known.

In some embodiments, the first controller sends the message to the second controller by using an RPC module, and the RPC module can directly send the fault warning message to the second controller according to a json format. When a user starts the display device, the RPC module is initialized and then runs.

The RPC module can establish a link between the two controllers, shield the difference of the two controllers and realize the effect of mutual calling. In the scheme, when the fault alarm information of the main system (the first controller) is sent to the second display for displaying, the sent information needs to adopt a json structure, and the data at least comprises two fields of a fault state and the fault alarm information. Furthermore, the invocation of RPC may be limited by the way it is compiled. For example, the RPC is compiled by Android bionic, and if the whole middleware program (hstvos process) uses a Linux compiling mode, the RPC cannot be directly called. The invention adopts a mode of directly programming the client code of the RPC module into a whole machine middleware program to solve the problem that the RPC can not be directly called due to platform difference.

In other embodiments, the first controller may not use the RPC module to transmit the information, but may use a broadcast manner to transmit the information. I.e. the first controller is performing sending fault alarm information to the second controller, is further configured to perform the steps of: generating a fault broadcast including fault warning information; and sending the fault broadcast carrying the fault warning information to the second controller.

The RPC module is sent in a broadcast mode, so that the problem that the RPC module cannot be directly called in a Linux compiling mode can be solved. Therefore, the two information sending modes can ensure the stability of sending the fault warning information from the first controller to the second controller.

After the first controller sends the fault warning information to the second controller, the second controller sends the fault warning information to the second display so that the second display can display the fault warning information.

A flow chart of a method for the second controller to send fault warning information to the second display according to some embodiments is illustrated in fig. 15. Referring to fig. 15, the second controller, in performing the sending of the fault warning information to the second display for display, is further configured to perform the following steps:

and S51, receiving the fault warning information sent by the first controller.

And S52, analyzing the fault alarm information and extracting a fault alarm text.

And S53, generating a fault alarm code corresponding to the fault alarm text, wherein the fault alarm code is used for representing the alarm content corresponding to the target fault subclass.

And S54, sending the fault warning code to a second display for displaying.

And the second controller receives the fault alarm information from the first controller and analyzes the fault alarm information to obtain a fault alarm text. The fault alarm text can comprise a first fault code and can also comprise the first fault code and repair measure prompt information.

And generating a fault alarm code which can be displayed by the second display according to the fault alarm text, namely the alarm content corresponding to the target fault subclass. And sending the fault warning code to a second display, and displaying the fault warning code by the second display. If the fault alarm text can include a first fault code, the fault alarm code includes the first fault code; if the fault alarm text comprises the first fault code and the repair measure prompt message, the fault alarm code comprises the first fault code and the repair measure prompt message.

A first display diagram of the second display displaying fault warning information according to some embodiments is illustrated in fig. 16. Referring to fig. 16, the fault warning code is a 16-system fault code, and if the target fault subclass is "fan 4 fault", the first fault code is "0 x 14", and "1" represents the fault class, i.e., fan fault; "4" represents the fault subclass, i.e., the fourth fan fault. At this time, the second controller generates the failure warning code as the first failure code "0 x 14", and "0 x 14" is displayed on the second display. The user can know that the fourth fan of the display device is out of order by seeing "0 x 14" displayed in the second display.

In another embodiment, the second display may display an english warning message in addition to displaying the malfunction warning code to prompt the user to display the malfunction type of the device. At the moment, the second controller generates corresponding English warning information according to the received fault warning information, and the English warning information is displayed by the second display.

A second display diagram of a second display displaying fault warning information according to some embodiments is illustrated in fig. 17. Referring to fig. 17, if the display device has a heat dissipation failure, english alarm information "temperature error" is displayed in the second display.

When the display device fails, the first display needs to be powered off in order to avoid the display screen of the display device from presenting a failure state and affecting the experience of the user. At this time, the first controller is further configured to perform the steps of:

and step 61, generating a first display closing notice after the fault warning information is sent to the second controller.

Step 62, sending a first display shutdown notification to the first display, the first display shutting down in response to the first display shutdown notification.

And when the first controller sends the generated fault warning information to the second controller and the second display is used for displaying, meanwhile, a first display closing notice is generated and sent to the first display so as to control the first display to be closed. At the moment, the display equipment only displays the fault warning information through the second display, and the first display is closed, so that a user can timely know that the display equipment has a fault problem.

And the user can know that the current display equipment has a fault according to the fault alarm information displayed by the second display, and can immediately repair the display equipment. Because the hstvos process in the first controller (main system) monitors the fault state of the display device in real time, after the display device is repaired, the hstvos process can monitor that the display device is not in the fault state.

In some embodiments, after the display device has gone through the failure and the failover, the first controller is further configured to:

and step 71, judging whether the second display displays the fault alarm information or not when the display equipment is not monitored to be in the fault state.

And step 72, if the fault alarm information is displayed in the second display, generating a fault alarm information cancellation display notice.

And 73, sending the fault alarm information cancellation display notification to the second controller, and canceling the fault alarm information displayed in the second display by the second controller in response to the fault alarm information cancellation display notification.

And the hstvos process monitors the fault state of the display equipment in real time, and when the situation that the display equipment is not in the fault state is monitored, the first controller controls the second display to cancel displaying the fault alarm information. Therefore, it is first determined whether the second display displays the fault warning information.

The first controller detects whether the second display displays the fault warning information or not, and the fault warning information can be displayed through the second controller, namely the second controller detects whether the second display displays the fault warning information or not, and feeds back the detection result to the first controller in real time.

If the fault warning information is not displayed in the second display, the hstvos process in the first controller continues to monitor the fault state of the display device in real time. If the display device is not in the failure state and the failure warning information is still displayed in the second display, the display of the second display is canceled at this time. Accordingly, the first controller generates a failure warning information cancellation display notification.

The first controller transmits a failure warning information cancellation display notification to the second controller, and the second controller causes the second display to cancel displaying the failure warning information in response to the failure warning information cancellation display notification.

Therefore, the display device provided by the embodiment displays the fault warning information by using the configured display, so that a user can know that the display device has a fault in time and know the fault type at any time. On the basis of the display device provided by the above embodiment, the display device can utilize the configured display to display the fault warning information and simultaneously utilize the LED warning lamp to prompt the display device that the fault occurs.

In some embodiments, the display device has the dual functions of displaying fault warning information by using a display configured by the display device and prompting by using an LED warning lamp. Therefore, to implement the prompt, the display device provided in the embodiment of the present invention further includes: and the LED warning lamp is connected with the first controller.

Another flow diagram of a method of displaying fault alarm information according to some embodiments is illustrated in FIG. 18. Referring to fig. 13 and fig. 18, in the display device according to the embodiment of the present invention, on the basis of the scheme that the display configured by the display device according to the foregoing embodiment displays the fault warning information, the first controller is further configured to:

and S81, when the display equipment is in a fault state, acquiring a second fault code written in a second register, wherein the second register is used for writing a fault code corresponding to the fault type.

And S82, determining a target fault class corresponding to the fault state of the display device according to the second fault code and a second fault type comparison table, wherein the second fault type comparison table comprises a plurality of fault codes and fault classes corresponding to one.

And S83, setting the appointed flicker times of the LED warning lamp according to the target fault category, wherein the appointed flicker times are used for prompting the fault type corresponding to the current display equipment in the fault state.

When the LED warning lamp is used for prompting that the display equipment has faults, the fault code acquired by the first controller is the fault code written in the second register. And when the display equipment is in a fault state, namely after the monitoring thread of the display system detects a fault flag bit, acquiring a corresponding fault code written in the register.

In some embodiments, the second register may be a 0x08 register. The second register is used for writing a fault code corresponding to the fault type of the fault class, so that the fault code can judge the fault class to which the fault state of the display device belongs.

Because different registers correspond to different fault type comparison tables, when a second fault code written in the second register is acquired, the compared fault type comparison table is the second fault type comparison table. The second fault type comparison table comprises a plurality of fault codes and fault classes which correspond one to one. And comparing the second fault code with the second fault type comparison table to determine a target fault class corresponding to the second fault code, wherein the target fault class is the fault type corresponding to the current display equipment when the current display equipment has faults.

The LED warning lamp prompts a user that the display equipment has faults through the flashing times, and different flashing times can be set for different fault types in order to distinguish the fault types. For example, if the target failure category is "fan failure", the specified number of blinks of the LED warning lamp is set to n₁Then, the user sees that the LED warning lamp flickers by n₁Then, the current fan fault of the display equipment can be known; if the target fault is a color wheel fault, setting the appointed flicker frequency of the LED warning lamp as n₂Then, the user sees that the LED warning lamp flickers by n₂And then, the current display fault of the display equipment can be known.

Therefore, in the detection process of the display device, the display is used for displaying the fault warning information and the LED warning lamp is used for prompting, so that a prompt with stronger visibility can be further provided for a user, and the user experience is improved.

As can be seen from the foregoing technical solutions, in the display device provided in the embodiments of the present invention, the first controller monitors whether the display device is in a fault state, and when the display device is in the fault state, the first fault code written in the first register is acquired, the target fault subclass is determined based on the first fault code and the first fault type comparison table, the fault alarm information including the first fault code and the target fault subclass is generated and sent to the second controller, and the second controller sends the fault alarm information to the second display for display. Therefore, the display device provided by the embodiment of the invention utilizes the second display to display the fault warning information, can accurately prompt the fault warning information to a user in time, has stronger visibility, displays the fault warning information in real time, and can enable the user to know the fault type of the display device in the fault state at any time.

A flow chart of a method of displaying fault alarm information according to some embodiments is illustrated in fig. 12. Referring to fig. 12, an embodiment of the present invention provides a method for displaying fault warning information, which is applied to a first controller, and the method includes:

s1, monitoring whether the display equipment is in a fault state;
