Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. It will be apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.
Unless defined otherwise, technical or scientific terms used in embodiments of the present disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present disclosure belongs. The terms "first," "second," and the like, as used in this disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. Likewise, the word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
With the rapid development of display technology, a relatively perfect wired data transmission scheme is formed by large stage display, and in such a scene, large display devices formed by splicing are usually arranged, such as ground display of large outdoor exhibition such as background shifts and floors in spring and evening, olympic games and the like, and outer wall display of various movable buildings. The method solves the technical problems of high cost and difficult maintenance of a single large screen, has extremely high expandability, and can be suitable for displaying images with various sizes.
With the expansion of the display scene, the spliced screen is larger and larger, the required display units are more and more, and the requirement on the robustness of the system is also increased. In a spliced screen scene, due to wired or wireless connection among a plurality of display units, in the display process, the volume and the memory occupied by the display units through forwarding signals are increased, the heat dissipation of a display backboard is more and more difficult, and the risk of transmission failure of the whole link caused by failure of a certain display unit is greatly increased.
In order to solve the above-mentioned problems, an embodiment of the present disclosure provides a tiled display method, which is used in a tiled display screen to avoid transmission failure of an entire link due to a failure of a certain display unit.
Fig. 1 is a schematic flowchart of a tiled display method provided by an embodiment of the present disclosure, and as shown in fig. 1, the embodiment of the present disclosure provides a tiled display method, which is used in a tiled screen, where the tiled screen includes a plurality of display units, and the method includes:
for each display unit:
s11, obtaining information to be displayed, wherein the information to be displayed comprises complete picture information to be displayed by the spliced screen.
S12, determining the position information of the display unit in the spliced screen according to the IP address of the display unit and the first corresponding relation; the first correspondence relationship includes: correspondence between IP address and location information of each display unit.
S13, acquiring target display information of the display unit according to the position information and the information to be displayed of the display unit in the spliced screen, and displaying according to the target display information.
The spliced display method provided by the embodiment of the disclosure is used in a spliced screen, and for each display unit in the spliced screen, position information of the display unit in the spliced screen, namely the relative positions of the display unit in a plurality of display units, is determined through the IP address of the display unit and a first corresponding relation, wherein the first corresponding relation is the corresponding relation of the IP address of each display unit in the spliced screen and the position information of the display unit; and extracting target display information in the information to be displayed according to the position information and displaying the target display information. In the above-mentioned tiled display method, there is no connection between the plurality of display units, but the position information of the display unit is determined by the IP address of each display unit and the above-mentioned first correspondence relation. Compared with a spliced screen formed by a plurality of display units which are connected in a wired or wireless way, the transmission failure of the whole link caused by the failure of a certain display unit is avoided, and the robustness of the spliced screen is improved.
In some embodiments, the display unit includes a plurality of sub-pixels, each sub-pixel including n light emitting members, n being an integer greater than 1; obtaining information to be displayed, including:
the method comprises the steps of obtaining information to be displayed through n communication modes, wherein the information to be displayed obtained through an ith communication mode is used for driving an ith luminous element in each sub-pixel to display; i is more than or equal to 1 and less than or equal to n, wherein i is an integer.
In the spliced display, the transmission link of the information to be displayed is generally divided into two types of wired transmission and wireless transmission, and the possibility that the cable transmission mode has insufficient voltage supply and excessive wires have fire risk can occur due to the fact that a plurality of display units are arranged in the spliced screen; the wireless transmission method also has the possibility of signal interference. Therefore, in order to ensure the integrity of the display screen, it is generally necessary to backup the information to be displayed, and in the case that a certain transmission link of the information to be displayed fails, the display effect is not affected due to the backup link being set.
Fig. 2 is a schematic structural diagram of a plurality of sub-pixels of a display unit according to an embodiment of the disclosure.
In one example, as shown in fig. 2, each display unit includes a plurality of sub-pixels 20, and each sub-pixel 20 includes a first light emitting member 21, a second light emitting member 22, a third light emitting member 23, and a fourth light emitting member 24.
The step S11 of obtaining information to be displayed includes: the information to be displayed is obtained through a communication mode of 2.4Gwifi connection so as to drive the first light emitting element 21 to display; the information to be displayed is obtained through a communication mode of 5Gwifi connection so as to drive the second light emitting piece 22 to display; the information to be displayed is acquired through a communication mode of 4G GPRS connection so as to drive the third luminous element 23 to display; the information to be displayed is acquired through a communication mode of 5G GPRS connection so as to drive the fourth light emitting element 24 to display.
It should be noted that, in the tiled display method provided in the embodiment of the present disclosure, a plurality of light emitting elements are disposed in sub-pixels of a display unit to obtain information to be displayed in different communication manners. That is, the four communication methods in the above example exist simultaneously, and the four light emitters emit light simultaneously under each sub-pixel, and in the case where one of the communication links fails, the human eye cannot recognize the failure at the pixel level, so that the overall display effect of the display unit and the tiled screen is not affected in the case where the light emitters connected to the other three communication links operate normally.
In some embodiments, an embodiment of the present disclosure provides a tiled display method, where a plurality of display units are sequentially started according to a preset sequence; before determining the position information of the display unit in the spliced screen according to the IP address of the display unit and the first corresponding relation, the method further comprises:
and step A1, the display unit sends an IP acquisition request to the server at the starting moment so that the server distributes IP addresses for the display unit according to the time sequence of receiving a plurality of IP acquisition requests and determines a first corresponding relation.
Specifically, receiving an IP acquisition request sent by a plurality of display units at respective start moments; distributing IP addresses to the display unit according to the time sequence of receiving a plurality of IP acquisition requests, and determining a first corresponding relation; wherein, in the IP address configured for the display unit, the numerical value of the specific byte is determined according to the time sequence of receiving the IP acquisition request of the display unit.
It should be noted that, the specific byte of the IP address may be a fourth byte, for example, when the time sequence of receiving the IP acquisition request a by the server is the third IP acquisition request, the IP acquisition request a is forwarded to the IP pool, so that the IP address issued by the IP pool is xx.xxx.xx.3, and the IP address is allocated to the display unit that sends the IP acquisition request a. The specific bytes may be other bytes, and the disclosure is not limited thereto.
In some embodiments, the server assigning the IP address to the display unit according to a time sequence of receiving the plurality of IP acquisition requests may include:
sequentially forwarding a plurality of IP acquisition requests to an IP pool according to a receiving sequence so that the IP pool sequentially transmits IP addresses; and receiving the IP address issued by the IP pool and distributing the IP address to the display unit.
And step B1, receiving the IP address and the first corresponding relation allocated by the server.
In the tiled display method provided by the embodiment of the disclosure, the display unit sends an IP acquisition request to the server at the starting time of the display unit, and when the server receives one IP acquisition request, the server controls the IP pool to issue one IP address, and in the process of receiving the IP acquisition request and distributing the IP address, the corresponding relationship between the two is recorded. As the plurality of display units are sequentially started in a preset order, the IP addresses of the plurality of display units are sequentially configured in a progressive manner. After the distribution of the IP addresses of all the display units is finished, the server determines a first corresponding relation to distinguish the relative positions of the display units. The server sends the first corresponding relation to each display unit so that each display unit can determine the position information according to the first corresponding relation and the configured IP address.
Fig. 3 is a schematic flowchart of a method for determining the first correspondence provided in the embodiment of the present disclosure, and in the following, with reference to fig. 3, how the server determines the first correspondence before the step B1 is described in detail by way of a specific example.
In one example, as shown in fig. 3, the method for determining the first correspondence may include:
s31, the display unit sends an IP acquisition request to the server at the starting moment.
S32, the server receives the IP acquisition request and forwards the IP acquisition request to the IP pool.
S33, the IP pool issues an IP address when receiving an IP acquisition request under the control of the server.
It should be noted that, since the product numbers of the display unit are numbers accumulated according to a preset sequence, the IP addresses issued to the display unit by the IP pool under the control of the server are also numbers of the fourth byte thereof are sequentially accumulated according to the sequence, and then the IP numbers of the specific bytes in the IP addresses configured by the display unit are consistent with the product numbers thereof. The starting moments of the display units are started in turn according to the installation positions, for example, the display unit with the product number 1 is installed at the lower left corner position of the whole spliced screen, and is started first, the display unit with the product number 2 is installed above the display unit with the product number 1, and is started second, and so on. Based on this, a first correspondence relationship of the display unit IP address and the position information is formed.
S34, the server distributes the IP address to the display unit.
The above S31-S34 are repeatedly performed until all the display units are assigned IP addresses.
S35, the server forms a first corresponding relation between all the IP addresses of the display units and the position information.
In addition, the server can also weakly bind the IP address of each display unit with the MAC address of each display unit, so that the display unit does not need to be reassigned after being restarted, but continues to follow the IP address acquired before the last shutdown, thereby saving hardware resources and improving the display efficiency of the spliced screen.
In some embodiments, before determining the position information of the display unit in the spliced screen according to the IP address of the display unit and the first correspondence, the method provided in the embodiments of the present disclosure further includes:
and step A2, receiving a clock synchronization signal, wherein the clock synchronization signal carries clock information.
Specifically, the server configures IP addresses of the plurality of display units respectively, and sends clock synchronization signals to the plurality of display units, wherein the clock synchronization signals carry clock information, so that the plurality of display units set countdown time according to the clock information and product numbers of the display units.
And step B2, setting countdown time according to the clock information and the product number of the display unit, and sending confirmation information to the server at the moment when the countdown time arrives so that the server can determine the first corresponding relation according to the time sequence of receiving a plurality of confirmation information, wherein the confirmation information carries the IP address acquired in advance by the display unit.
Specifically, the server receives acknowledgement information sent by a plurality of display units at the time when the countdown time arrives, and determines a first corresponding relation according to the time sequence of receiving the plurality of acknowledgement information; the confirmation information carries the IP address where the display unit is configured.
In one example, the setting the countdown time may be to take the product of the clock information and the product number as the countdown time according to the clock information and the product number of the display unit. For example, if the time slot in the clock information is 1s, the countdown time set by the display unit with the product number 1 is 1s, the countdown time set by the display unit with the product number 2 is 2s, and so on. Based on this, the server can learn the product numbers of the plurality of display units according to the order of the received plurality of confirmation messages. The product numbers and the installed positions are preset and correspond to each other, so that after confirmation information of all the display units is received, a first corresponding relation between the IP addresses and the position information of the display units is formed.
It should be noted that, since the product performance of the display unit is not uniform, the display unit with better product performance and higher parameter configuration may operate at a faster speed, for example, in the millisecond range, whereas the display unit operates at a slower speed, for example, in the second range. Therefore, the clock information is used as the time slot coefficient of the countdown time so as to balance the difference of the product performances of different display units.
In addition, since the display unit has been configured with the IP address when the acknowledgement information is returned, the acknowledgement information is sent out through the TCP protocol, and the acknowledgement information itself carries the configured IP address regardless of the information content of the acknowledgement information.
And step C2, receiving the first corresponding relation sent by the server.
According to the spliced display method provided by the embodiment of the disclosure, the server configures the IP addresses at the starting time of the display units, and the server cannot know the corresponding relation between the product numbers of each display unit and the IP addresses although the server configures the IP addresses. Therefore, a broadcast signal, i.e., an instant sync signal, is issued to all display units to cause the display units to set a countdown time and to return a confirmation message at the end of the countdown time. On the one hand, the IP addresses of the display units are carried in the confirmation messages sent by the display units, on the other hand, the time sequence of the confirmation messages returned by the display units is consistent with the product number sequence of the confirmation messages, and based on the time sequence, a first corresponding relation between the IP addresses of the display units and the position information is formed.
Fig. 4 is a schematic flowchart of another method for determining the first correspondence provided in the embodiment of the present disclosure, and in the following, in conjunction with fig. 4, details of how the server determines the first correspondence before the above step C2 is described in a specific example.
In one example, as shown in fig. 4, the method for determining the first correspondence may include:
s41, the server configures an IP address for each display unit.
S42, the server sends clock synchronization signals to each display unit, wherein the clock synchronization signals carry clock information.
S43, the display unit sets countdown time according to the clock information and the product number of the display unit, and sends confirmation information to the server at the moment when the countdown time arrives, wherein the confirmation information carries the IP address configured by the display unit.
S44, the server determines a first corresponding relation according to the receiving time of the plurality of confirmation information and the IP address carried by the confirmation information.
S45, the server sends the first corresponding relation to the plurality of display units respectively.
In one embodiment, before determining the position information of the display unit in the spliced screen according to the IP address of the display unit and the first correspondence, the method further includes: and receiving a first corresponding relation sent by the server, wherein the first corresponding relation is prestored.
Specifically, before a plurality of display units are installed to form a spliced screen, a fixed IP address is burned for each display unit in sequence, then the display units are installed according to the product number sequence, and finally a first corresponding relation between the IP address and the position information of each display unit is stored in a server.
The embodiment of the disclosure also provides another tiled display method, which is used for a server respectively connected with a plurality of display units in a tiled screen, and includes:
and sending the first corresponding relation to the display unit so that the display unit can determine the position information of the display unit in the spliced screen according to the first corresponding relation and the IP address of the display unit.

The spliced display method is used for a server respectively connected with a plurality of display units in a spliced screen, and the first corresponding relation of the IP address and the position information of each display unit is determined through the server, so that the display unit can determine the position information of the display unit in the spliced screen according to the first corresponding relation and the IP address of the display unit. In the above-mentioned tiled display method, there is no connection between multiple display units, but the relative position of the display unit in the whole tiled screen is defined by combining the IP address of the display unit itself through the first correspondence between the IP address of each display unit and the position information determined by the server. Compared with a spliced screen formed by a plurality of display units which are connected in a wired or wireless way, the transmission failure of the whole link caused by the failure of a certain display unit is avoided, and the robustness of the spliced screen is improved.
In some embodiments, before sending the first correspondence to the display unit, the method further comprises:
receiving IP acquisition requests sent by a plurality of display units at respective starting moments; distributing IP addresses to the display unit according to the time sequence of receiving a plurality of IP acquisition requests, and determining a first corresponding relation; wherein, in the IP address configured for the display unit, the numerical value of the specific byte is determined according to the time sequence of receiving the IP acquisition request of the display unit.
