Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of a screen matching method for a tiled screen, it should be noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than here.
Fig. 2 is a screen configuration method of a spliced screen according to an embodiment of the present invention, including: the tiled screen includes a plurality of display elements, as shown in fig. 2, the method includes the steps of:
step S101, a first display unit receives a corresponding sorting instruction;
specifically, the sorting instruction is used for instructing the display unit to determine its own coordinates according to the sorting instruction. The ranking may be obtained from an external device (e.g., a transmitting card) through a communication interface provided on the first display unit.
At least one display unit on the edge of the splicing screen is connected with the sending card through a network cable, and the display unit connected with the sending card is a network port position display unit. In an alternative embodiment, the first display unit is a network location display unit, the first display unit has at least one input end, the input end may be disposed on the upper side or the left side, and the input end may be connected to the transmitting card through a network cable, so as to receive the sorting instruction transmitted by the transmitting card.
In another optional embodiment, the first display unit is a display unit in a non-portal position, and an input end of the first display unit is connected to an output end of the display unit adjacent to the left side and/or the display unit adjacent to the upper side through a network cable, so as to receive the sorting instruction output by the display unit adjacent to the left side and/or the display unit adjacent to the upper side.
It should be noted that the display units in this embodiment are display units that can form a large tiled screen by tiling. In the embodiment of the present application, the display unit may not be provided with the photosensor.
Step S102, a first display unit determines coordinate information of the first display unit according to a sorting instruction corresponding to the first display unit and sends a sorting instruction corresponding to a second display unit to the second display unit, wherein the sorting instruction corresponding to the second display unit carries the coordinate information of the first display unit and the size information of the first display unit, and the second display unit is a display unit adjacent to the first display unit in a preset direction;
the second display unit determines the coordinate information of the second display unit according to the coordinate information of the first display unit and the size information of the first display unit, and sends a sorting instruction corresponding to a third display unit to the third display unit, wherein the third display unit is a display unit adjacent to the second display unit in the preset direction.
Specifically, the preset direction may be four directions, namely, up, down, left, and right, of the first display unit, so that the second display unit may be spliced with any one direction of the four directions of the first display unit, specifically, the preset direction may be a direction in which an output port of the display unit is located, for example, the right of the first display unit has the output port, and the second display unit may be spliced on the right of the first display unit to obtain the sorting instruction forwarded by the first display unit.
Because the sorting instruction is input into the spliced screen from the first display unit, and the coordinate of the first display unit can be regarded as the reference coordinate of the coordinate information determined by the second display unit, the sorting instruction corresponding to the second display unit carries the coordinate information of the first display unit and the coordinate information of the first display unit. When the second display unit determines the coordinate information of the second display unit, the size information of the first display unit is correspondingly added or subtracted to the coordinate information of the first display unit according to the position information of the second display unit relative to the first display unit, and then the coordinate information of the second display unit can be obtained. For example, fig. 3 is a schematic diagram of data transmission when an optional tiled screen is configured according to an embodiment of the present invention, the tiled screen may be composed of display units denoted by ID0-ID15, taking fig. 3 as an example, the first display unit may be ID0 in fig. 3, the second display unit may be ID1 in fig. 3, the coordinate information (using a two-dimensional X and Y coordinate system) of ID0 is (0, 0), the size information of the display unit ID0 is 104 × 104 pixels, and the ID1 adjacent to the ID1 in the X axis direction obtains the coordinate information of (104, 0) of the second display unit.
Correspondingly, after the coordinate information of the second display unit is obtained, the second display unit sends a sorting instruction to the adjacent third display unit, and so on, according to the steps, each display unit on the spliced screen can obtain the coordinate information with the adjacent display unit as the reference coordinate.
In the steps, the sequencing instruction is sent to the first display unit, other display units perform corresponding calculation according to the coordinate information of the adjacent display units, the coordinate information of all the display units on the spliced screen can be obtained, communication between the display units can be realized only by arranging the network input port and the network output port on the display units without using the photoelectric receiving and sending device, further, an additional circuit is not needed to be added, the hardware cost is saved, the problem that the screen cost is high due to screen matching of the spliced screen depending on the photoelectric receiving and sending device is solved, the coordinates of all the display units can be obtained according to the coordinate information sent by the adjacent display units, and the control method is simple. In addition, because a photoelectric sensor is not needed, the adjacent display units are not required to be aligned strictly when being spliced, and the assembly requirement of the spliced screen is reduced.
Optionally, the method further includes: the first display unit receives an image to be displayed; the first display unit intercepts an area corresponding to the first display unit from the image to be displayed according to the coordinate information and the size information of the first display unit; the first display unit sends an image to be displayed to the second display unit.
The image to be displayed is an image displayed after the plurality of display units of the spliced screen are spliced. The first display unit is used as an input port, firstly, an image with a corresponding size is intercepted according to the coordinate information and the size information of the first display unit, the image to be displayed is forwarded to the second display unit, and correspondingly, the second display unit intercepts the corresponding image according to the coordinate information and the size information of the second display unit. By analogy, all display units in the spliced screen can intercept corresponding images according to the coordinate information and the size information of the display units, and spliced display of the images to be displayed is achieved.
Optionally, the first display unit includes two input terminals, and the first display unit receives an image to be displayed, including: the first display unit receives the image to be displayed once through two input ends respectively.
The first display unit has two inputs respectively located on the different directional sides of ID 0. As shown IN FIG. 3, the display element ID0 has 2 inputs (i.e., IN ports IN FIG. 3), two IN ports located on the upper and left sides of the ID0, respectively. Correspondingly, the external device is provided with two sending ports which correspond to the two input ends of the first display unit one by one to form two paths of image transmission channels. On one hand, because the bandwidth of the single-channel image transmission channel is limited, and the size of the image to be displayed is limited, under the condition of displaying a larger image, the image to be displayed can be divided into two parts, and the two parts are respectively input into the first display unit through the two input ends, so that the size of the image which can be carried by the spliced screen can be improved, and the image with the larger size can be displayed by splicing.
Optionally, the tiled screen is divided into a plurality of regions, each region includes a display unit connected to the transmitting card, and the display unit connected to the transmitting card receives region images corresponding to all the display units in the region to which the display unit connected to the transmitting card belongs, where the transmitting card acquires coordinate information of each display unit and determines images corresponding to all the display units in the region to which the display unit connected to the transmitting card belongs according to the coordinate information of all the display units.
The sorting instruction and the image to be displayed in step S101 may be sent by a sending card controlled by an external upper computer or directly sent by the sending card, and transmitted to the input end of the first display unit through the network port of the sending card. The tiled screen can be divided into a plurality of regions, each region is provided with a display unit connected with the sending card to receive the region image corresponding to all the display units in the region, for example, as shown in fig. 3, the tiled screen is divided into two regions, ID0 and ID8 are the display units connected with the sending card in the two regions, the region where ID0 is located belongs to the region where the display units of ID0-ID7 are located, and the region where ID8 is located belongs to the region where the display units of ID8-ID15 are located. The input end of the ID0 can receive the area images of the IDs 0-ID7, the ID0 intercepts the corresponding images according to the coordinate information of the ID0 and forwards the area images to the ID1, the ID1 intercepts the corresponding images of the area images according to the coordinates and the size of the ID1 and forwards the corresponding images to the ID2, and so on, so that the IDs 0-ID7 all obtain the corresponding images. Correspondingly, the input end of the ID8 can receive the area images of the IDs 8-ID15, the ID8 intercepts the corresponding images according to the coordinate information of the ID8 and forwards the area images to the ID9, and so on, so that the IDs 8-ID15 all obtain the corresponding images.
Optionally, the method further includes: receiving a coordinate information modification instruction, wherein the modification instruction is used for modifying the coordinate information of the appointed display unit; modifying the coordinate information of the appointed display unit according to the modification instruction; and adjusting the coordinate information of other display units in the spliced screen according to the coordinate information of the appointed display unit.
The coordinate information modification instruction may be manually input. Any one display unit in the spliced screen can receive the coordinate information modification instruction, and because all the display units acquire the coordinate information with the coordinate of the first display unit as the reference coordinate according to the steps S101-S102, the coordinate information of each display unit is modified through corresponding addition or subtraction according to the determined sorting information. Execution of the coordinate information modification instructions may be represented on the tiled screen as image offsets in units of rectangular boxes.
Optionally, in a case that two display units adjacent to any one display unit both send the sorting instruction to the display unit, the display unit receives the sorting instruction sent by one adjacent display unit according to a preset priority.
It should be noted that some touch screens in the middle receive the sorting commands from two adjacent display units, but the coordinates of the touch screens can be determined according to any sorting command, so that only one touch screen can be received according to the preset priority. As shown IN fig. 3, two input terminals IN of ID5, ID6, ID7, ID9, ID10, ID11, ID13, ID14, and ID15 each have other adjacent display units, that is, each is connected to an output terminal OUT of the other adjacent display units, for example, two IN terminals of ID5 are connected to an output terminal OUT of ID1 and an output terminal OUT of ID4, respectively, so that ID5 can receive sorting instructions from ID1 and ID4, and ID5 selects to receive sorting instructions from only one display unit of ID1 and ID4 according to a preset priority, and rejects to execute the sorting instructions of the unselected display units.
The preset priority is used for enabling the display unit to determine the coordinate information of the display unit according to the unique sorting instruction, the situation that the sorting of the display unit is disordered due to the fact that reference coordinates except the coordinate information of the first display unit exist in the spliced screen is avoided, the preset priority can be flexibly set, and the setting is not limited.
IN an alternative embodiment, the preset priority may be that the primary data has priority over the backup data, and the data on the left has priority over the data above, for example, two IN terminals of the display unit ID5 are respectively connected to the output terminal OUT of the ID1 and the output terminal OUT of the ID4, when the sorting command issued by the OUT of the ID1 and the ID4 is received at the same time, it is determined whether the data of the ID1 and the ID4 is the primary data or the backup data, if the data issued by the OUT port of the ID1 is the primary data and the data output by the ID4 is the backup data, the sorting command issued by the ID1 is received preferentially, and accordingly, the ID5 will refuse to execute the sorting command issued by the ID 4. If the ID1 and the ID4 are both main data, the position relationship between the ID1 and the ID4 and the ID5 is further judged, the ID1 is positioned above the ID5, the ID4 is positioned on the left side of the ID5, the ID5 preferentially receives the sorting instruction sent by the ID4 positioned on the left side of the ID5, and correspondingly, the sorting instruction sent by the ID1 is refused to be executed.
It should also be noted that some display units, when receiving an image, still have two adjacent display units transmitting to them. In an alternative scheme, only one image may be received according to a preset priority, and in another alternative scheme, images sent by two adjacent display units are received and are redundant with each other.
Optionally, the first display unit is a display unit at the upper left corner of the tiled screen, and the preset direction is the right side and the lower side.
The first display unit is located at the upper left corner of the spliced screen, so that the sorting instructions and the transmission of the images to be displayed are distributed on the spliced screen from left to right and from top to bottom, and all the display units on the spliced screen can accurately display corresponding image information. As shown IN FIG. 3, the input terminals IN and the output terminals OUT of the display units on the spliced screen are arranged from left to right and from top to bottom, ID0 is the display unit at the upper left corner, the sorting instruction and the image to be displayed are input from the IN port at the left side of ID0, and are respectively forwarded from the OUT port at the right side of ID0 to ID1, and are forwarded from the OUT terminal at the lower side of ID0 to ID4, and because the arrangement directions of the IN terminal and the OUT terminal of ID0-ID15 are the same, according to the rule from left to right and from top to bottom, the ID0-ID15 can all acquire the respective coordinate information and intercept the corresponding image.
In the above embodiment, the first display unit may also be located in the middle of the tiled screen, but only the display units located at the right and lower sides of the first display unit may receive the sorting command, and the areas at the left and upper sides of the first display unit may not obtain the sorting command. As shown IN FIG. 3, if the first display unit is ID4, the ID0-ID3 above it according to the arrangement rule of the IN terminal and the OUT terminal will not be able to obtain the sort command.
Through the steps, the position of the first display unit is selected to be the upper left corner, and therefore the display unit in the spliced screen can be utilized to the maximum.
It should be noted that, if the preset direction is left and upper, the first display unit may also be disposed at the lower right corner of the tiled screen.
Fig. 3 is a schematic diagram of an alternative spliced screen structure and a data transmission path according to the above-mentioned screen matching method, and the direction of an arrow in fig. 3 is a data transmission direction. As shown IN fig. 3, the tiled screen includes 16 display units including ID0-ID15, each display unit has size information of 104 × 104 pixels, ID0 is that the first display unit can obtain sorting instructions and image data from an external sending card, ID0 has two input terminals IN, the IN port on the left is connected with the portal 1 of the sending card, the sorting instructions and image data are transmitted from the portal 1 of the sending card to the IN port on the left of ID0, and ID0 can forward the sorting instructions IN the X direction and the Y direction through the OUT port thereof, respectively.
ID0 is the display element in the upper left corner of the display screen, and the coordinate information of ID0 is (0, 0). The IN and OUT terminals of ID0-ID15 are arranged IN the same direction (the left and upper sides of the display unit are the IN ports and the right and lower sides are the OUT ports), sort instructions and images to be displayed are input from the IN port on the left side of ID0 and are forwarded from the OUT terminal on the right side of ID0 to ID1 and from the OUT terminal on the lower side of ID0 to ID4, respectively. Specifically, ID0 sends a sorting instruction including ID0 coordinate information (0, 0) and size information and image data to ID1 through its right OUT port, ID1 obtains its coordinate information as (104, 0) from the coordinate information (0, 0) and size information of ID0, and cuts OUT image information by size 104 × 104 pixels, and then sends a sorting instruction including ID1 coordinate information (104, 0) and size information and a graphic to be displayed simultaneously to ID2 through its right OUT port and ID5 through its lower OUT port, respectively, through its right OUT port and its corresponding size information. The ID4 obtains the coordinate information of (0, 104) from the coordinate information (0, 0) and size information of the ID0, and cuts OUT the image information by 104 pixels in size 104 × 104, and then simultaneously sends a sorting instruction containing the ID4 coordinate information (0, 104) and size information and the graphics to be displayed to the ID5 through the OUT port on the right side of the ID4 and the ID8 through the OUT port on the lower side thereof.
The sorting instruction and the image to be displayed are forwarded to IDs 1-15 in order from left to right, top to bottom. For a display unit having two IN ports, IN the case where the data on the left side is higher IN priority than the data on the upper side, the sort instruction transmitted by the display unit on the left side is preferentially received. Taking ID5 as an example, ID5 receives the sorting instruction and the image forwarded by ID4 and ID1 at the same time, ID5 receives the sorting instruction containing ID4(0, 104) coordinate information according to priority, and accordingly determines its own coordinate information as (104 ), and intercepts the corresponding image according to its size of 104 × 104 pixels.
Similarly, ID6 determines coordinate information and images according to sorting instructions forwarded by ID5, ID7 determines coordinate information and images according to sorting instructions forwarded by ID6, ID8 determines coordinate information and images according to sorting instructions forwarded by ID4, ID9 determines coordinate information and images according to sorting instructions forwarded by ID8, ID10 determines coordinate information and images according to sorting instructions forwarded by ID9, ID11 determines coordinate information and images according to sorting instructions forwarded by ID10, ID12 determines coordinate information and images according to sorting instructions forwarded by ID8, ID13 determines coordinate information and images according to sorting instructions forwarded by ID8, ID14 determines coordinate information and images according to sorting instructions forwarded by ID13, ID15 determines coordinate information and images according to sorting instructions forwarded by ID14, and IDs 0-ID15 in the display screen all obtain their respective coordinate information and image data.
As an alternative embodiment, the sending card includes a network port 1 and a network port 2, the network port 1 may be used for transmission of main data, and the screen configuration of the spliced screen is implemented according to the above steps. As shown IN FIG. 3, Port 2 is connected to the IN port to the left of ID8, the left port of ID8 is not open, and only the upper IN port is open for receiving sort instructions. Under the condition that the IN port on the left side of the ID8 is enabled, the spliced screen is divided into two areas, ID0 and ID8 are display units connected with the sending card IN the two areas respectively, the area where the ID0 is located belongs to the areas where the ID0-ID7 display units are located, and the area where the ID8 is located belongs to the areas where the ID8-ID15 display units are located.
