As shown in fig. 4, a display device screen matching method 40 of this embodiment is, for example, applied to a display device screen matching system including a display device, where the display device includes a plurality of display units arranged in a matrix, and each of the display units includes: the first network port, the second network port, the third network port and the fourth network port. Specifically, the display device screen matching method 40 is applied to the display device screen matching system 50 according to the third embodiment, for example, and the display device screen matching method 40 mainly includes:
specifically, assuming that the display apparatus 20 includes 4 × display units 21, each display unit 21 is mounted in the arrangement shown in fig. 2, and the position coordinate expression of each display unit 21 is (i, 0) assuming that the display apparatus 20 includes 4 display units 21, each display unit 21 is mounted in the arrangement shown in fig. 2x，jy) Wherein ixIs the abscissa, jyIs ordinate and the value of x, y ranges for the 4 × 4 display cell arrayAll of them are 0 to 3. Powering on all the display units 21, initializing each display unit 21 under the control of each display control card 13, so that each display unit 21 has an initial coordinate, for example, (0, 0) (this is merely an example and is not intended to limit the present invention, and for example, other values such as (1,1) may also be used), that is, an initial coordinate (i)x，jy)＝(0，0)。
Step S33: after the initialization, the first network port of each display unit is controlled to periodically send the abscissa and the ordinate of the display unit per se to the third network port of the adjacent display unit for multiple times along a first direction within preset time, and the assignment of the abscissas of the display units is completed to obtain the assigned abscissa; and after the initialization, controlling the second net port of each display unit to periodically send the abscissa and the ordinate of the display unit per se to the fourth net port of the adjacent display unit for multiple times along a second direction within preset time, and finishing assignment of the ordinate of the plurality of display units to obtain the assigned ordinate. Specifically, for example, after step S31, the first portal 151 of each display unit 21 is controlled to periodically send the position information of the display unit 21 itself to the third portal 175 of the adjacent display unit 21 and further to the third portal 155 of the adjacent display unit 21 through the first interface 171 a plurality of times in the first direction (for example, the horizontal right direction of the image shown in fig. 2) within a preset time, and finally, the assignment of the abscissa of the plurality of display units 21 is completed to obtain the assigned abscissa; and controlling the second portal 153 of each display unit 21 to periodically send the position information of the display unit 21 itself to the fourth interface 177 of the adjacent display unit 21 and further to the fourth portal 157 of the adjacent display unit 21 through the second interface 173 for multiple times along a second direction (for example, a vertical downward direction of the image shown in fig. 2) within a preset time, and finally completing assignment of the ordinate of the plurality of display units 21 to obtain an assigned ordinate; the assigned abscissa and the assigned ordinate of the plurality of display units 21 together constitute assigned coordinates of the plurality of display units 21.
Specifically, the display control card 13 controls the first portal 151, the second portal 153, the third portal 155, and the fourth portal 157 to enter a screen configuration working mode, so as to assign coordinates to each display unit 21. Under the control of the display control card 13, the first portal 151, the second portal 153, the third portal 155 and the fourth portal 157 operate in different modes. For example, the embodiment may control the first internet access 151 and the second internet access 153 to operate in the signal transmission mode, and the first internet access 151 and the second internet access 153 are only responsible for transmitting signals to the adjacent display units; the third internet access 155 and the fourth internet access 157 work in a signal receiving mode, and the third internet access 155 and the fourth internet access 157 are only responsible for receiving signals sent by the adjacent display units 21. And because the directions of the signals transmitted or received by the two network ports in the same working mode are perpendicular to each other, one display unit simultaneously has two directions of signal transmission or signal reception perpendicular to each other, such as a first direction and a second direction perpendicular to each other. The following describes specific steps by taking the first direction as the horizontal right direction of the image shown in fig. 2 and the second direction as the vertical downward direction of the image shown in fig. 2, in conjunction with the display device 20 shown in fig. 2 as an example:
specifically, the first network port 151 in the display unit 21 to be coordinate periodically sends its current coordinate signal to the display unit on the adjacent right side n times all the time in the first direction (horizontally to the right) within a preset time period, and the third network port 155 receives the current coordinate signal of the display unit 21 on the adjacent left side n times from the display unit 21 on the adjacent left side; n is a natural number other than 0 and typically takes a value not smaller than the number of columns of the display unit 21.
Similarly, the second port 153 of the display unit 21 to be co-ordinated periodically sends m times its current coordinate signal to the display unit directly below the adjacent unit all the time in the second direction (vertically downward) within a preset time period, and the fourth port 157 receives m times the current coordinate signal of the display unit 21 directly above the adjacent unit 21; m is a natural number other than 0 and typically takes on a value no less than the number of rows of the display unit.
Each display unit 21 initially has initial coordinates (0, 0), and one of the display units 21 is arbitrarily selected to beThe coordinate-fixed display unit 21 introduces a specific coordinate assignment process, for example, selecting the second row and the second column of display units 21 in fig. 2 as the display units to be coordinate (i)2，j2)。
Display unit to be coordinated (i)2，j2) The third portal 155 of (a) receives the adjacent left display element (i) for the first time2，j1) After the 1 st current coordinate signal (the current coordinate signal is (0, 0)) is sent out, a specified value such as 1 is added to the abscissa of the received current coordinate signal (0, 0), and then the obtained abscissa is assigned to the display unit (i) with coordinates to be determined, namely, the display unit with coordinates to be determined2，j2) The current coordinate signal at this time becomes (1, 0);
similarly, the display unit (i) to be coordinated2，j2) The fourth portal 157 receives for the first time the display unit (i) directly above the next one1，j2) After the 1 st current coordinate signal (the current coordinate signal is (0, 0) for example) is sent out, a specified value such as 1 is added to the ordinate of the received current coordinate signal (0, 0) and then the coordinate is given to the display unit (i) of the vertical coordinate, namely the undetermined coordinate2，j2) The current coordinate signal is (0, 1);
the processes of assignment of the abscissa and assignment of the ordinate can be regarded as occurring simultaneously, so that the display unit (i) to be assigned coordinates is comprehensively acted2，j2) The 1 st update coordinate (1,1) is obtained. Furthermore, it is understood that the first direction may transmit only the abscissa signal, and the second direction may transmit only the ordinate signal.
In light of the above, the display unit (i) having the 1 st updated coordinates (1,1)2，j2) Will successively receive the display unit (i) on the adjacent left side2，j1) Sending out a 2 nd time current coordinate signal, a 3 rd time current coordinate signal, … … and an nth time current coordinate signal, and performing the following operations:
for example, adjacent left display cell (i)2，j1) The abscissa of the emitted 2 nd time current coordinate signal is the same as that of the 1 st time current coordinate signal, and the display with the 1 st updated coordinate (1,1) is maintainedUnit (i)2，j2) Does not change. Similarly, it is foreseen that the adjacent left display element (i)2，j1) The sent nth time current coordinate signal is the same as the abscissa in the (n-1) th time current coordinate signal, and the display unit (i) with the 1 st updated coordinate (1,1)2，j2) Will remain unchanged continuously. After a predetermined time period, or for example after a sufficient number of signal transmissions, for example 200 (n 200), the first portal 151 will no longer transmit a signal, and the display unit (i) with the 1 st updated coordinate (1,1)2，j2) Will be retained.
As another example, a display unit (i) of the second row and the third column is selected2，j3) For the tiled display unit with undetermined coordinates, the final position coordinates (1,2) can be obtained according to the same position coordinate assignment mode, and specifically, the final position coordinates can be:
display unit to be coordinated (i)2，j3) The third portal 155 receives the adjacent left display element for the first time (i)2，j2) After the 1 st current coordinate signal (0, 0) is sent out, a specified value is added to the abscissa on the received current coordinate information (0, 0), for example, 1 is added, and then the abscissa of the display unit (i) is assigned, namely the display unit (i) of the coordinate to be determined2，j3) The current coordinate signal is (1, 0);
similarly, the display unit (i) to be coordinated2，j3) The fourth portal 157 receives for the first time the display unit (i) directly above the next one1，j3) After the sent 1 st current coordinate signal is (0, 0), adding a specified value such as 1 to the ordinate of the received current coordinate information (0, 0), and then assigning the ordinate, namely the splicing display unit (i) with undetermined coordinate2，j3) The current coordinate signal is (0, 1);
the processes of assignment of the abscissa and assignment of the ordinate can be regarded as occurring simultaneously, so that the display unit (i) to be assigned coordinates is comprehensively acted2，j3) The 1 st update coordinate (1,1) is obtained.
Thereafter, when the display unit (i) having the 1 st updated coordinates (1,1)2，j3) Will successively receive the display unit (i) on the adjacent left side2，j2) Sending out a 2 nd time current coordinate signal, a 3 rd time current coordinate signal, … … and an nth time current coordinate signal, and performing the following operations:
for example, adjacent left display cell (i)2，j2) The 2 nd current coordinate signal (as can be seen from the above description, it corresponds to the tiled display unit (i)2，j2) Is different from the 1 st current coordinate signal (initial coordinate (0, 0)), the display unit (i) displays the current coordinate signal (1,1) < th > and the current coordinate signal (initial coordinate (0, 0) < th > and the current coordinate signal < th > is different from < th > and the current coordinate signal < th > is the same from < st > and the current2，j3) Adding a specified value such as 1 to the abscissa of the 1 st updated coordinate and then assigning the value to the abscissa of the user; i.e. tiled display unit (i)2，j3) The 2 nd update coordinate is obtained as (2, 1).
Similarly, it is foreseen that the display unit (i) adjacent to the left side2，j2) The 3 rd time current coordinate signal is the same as the 2 nd time current coordinate signal, and the display unit (i) with the 2 nd updated coordinate (2, 1)2，j3) The abscissa of (a) will be kept unchanged. After a predetermined time period, or for example, when the number of signal transmissions reaches a sufficient number, for example, 200 (n is 200), the first portal 151 will no longer transmit a signal, and the 2 nd display unit (i) of the updated coordinates (2, 1) will update the coordinates (2, 1)2，j3) Will be retained.
As can be seen from the above, in the display device of this embodiment, in the screen configuration operating mode, the fourth network interface 157 or the third network interface 155 of the display unit located in the first row or the first column respectively does not receive any signal, so that the ordinate of the display unit located in the first row is always 0; the abscissa of the display unit in the first column is always 0, and naturally, the tiled display unit (i) located at the top left corner of the whole display device can also be determined1，j1) The initial coordinates (0, 0) of (a) do not change and can be considered as the initial origin of the screen.
