FIG. 5 is a flow chart of another embodiment of a method for setting a display device according to the present invention.

In the following, a plurality of embodiments of the present invention will be disclosed in the context of a textual description. For the sake of clarity, a number of practical details will be described in the following description. However, it should be understood that these practical details are not applied to limit the creation. In addition, some of the known structures and elements are illustrated in the drawings in a simplified schematic representation.

Please refer to the steps in FIG. 1A and FIG. 1B, and please refer to the schematic diagrams of FIG. 2A to FIG. 2G. As shown in FIG. 1A and FIG. 2A, step (S1): selecting a display device as a starting display device and setting a first coordinate information. As shown in the figure, a plurality of display devices are arranged in a matrix, and each of the display devices is respectively provided with a microprocessor (not shown), and faces the first direction, the second direction, the third direction, and the The first transceiver T1, the second transceiver T2, the third transceiver T3, and the fourth transceiver T4 are respectively disposed on the sides of the four directions. The transceiver type is preferably a contactless transceiver, such as an infrared (IR) transceiver, a Bluetooth transceiver, a Near Field Communication (NFC) transceiver, or the like. The transceiver, but not limited to this, can also be a contact transceiver. Wherein, the first direction is along the positive x-axis direction, the second direction is along the positive y-axis direction, the third direction is along the negative x-axis direction, and the fourth direction is along the negative y-axis direction.

In this embodiment, an optional display device is used as the starting display device D1, and the first coordinate information, that is, D1 (128, 128) is set. It should be noted that since the starting display device D1 can be arbitrarily selected, the display device as the starting display device does not know its own correct coordinate information at first, so the coordinate values in this embodiment are only used as hypothetical coordinates. Information is not necessarily the most correct coordinate information. It is hereby stated.

Please refer to FIG. 1A, FIG. 2A and FIG. 2B. Step (S2): the first transceiver, the second transceiver, the third transceiver, and the fourth transceiver of the initial display device are respectively along the first direction, The second direction, the third direction, and the fourth direction sequentially trigger adjacent display devices and provide corresponding coordinate information. As shown in FIG. 2A, the first transceiver T1, the second transceiver T2, the third transceiver T3, and the fourth transceiver T4 of the initiating display device D1 are respectively in the first direction, the second direction, the third direction, and the first Four adjacent directions trigger adjacent display devices.

Next, as shown in FIG. 2B, the first transceiver T1 detects the display device D and sets corresponding coordinate information thereto. In this embodiment, the display device D is located on the right side of the start display device D1 in the first direction. The position of the device is displayed, so the corresponding coordinate information of the display device D is set to D (128+1, 128), which is D (129, 128). Similarly, the second transceiver T2 detects the display device D0 in the second direction and sets corresponding coordinate information D0 (128, 128+1), that is, D0 (128, 129); the third transceiver T3 detects in the third direction. Display device D0 and set corresponding coordinate information D0 (128-1, 128), that is, D0 (127, 128); fourth transceiver T4 detects display device D0 in the fourth direction and sets corresponding coordinate information D0 (128, 128) -1), ie D0 (128, 127).

Please refer to FIG. 1A and FIG. 2C. Step (S3): setting a display device corresponding to the coordinate information, respectively triggering adjacent display devices to the end point display device along the first direction, the second direction, the third direction, and the fourth direction. As shown in FIG. 2C, through the display devices that have set the corresponding coordinate information in the previous step, namely D (129, 128), D0 (128, 129), D0 (127, 128), and D0 (128, 127), respectively, along the first direction, The two directions, the third direction, and the fourth direction continue to trigger adjacent display devices, triggering until the last display device in each of the directions, referred to herein as the endpoint display device D0. Briefly, the endpoint display device D0 has no other adjacent display devices in the first direction, the second direction, the third direction, and the fourth direction. By way of view, the endpoint display device in the first direction is D0 (130, 128), and the endpoint display device in the second direction For D0 (128, 129), the endpoint display device in the third direction is D0 (127, 128), and the endpoint display device in the fourth direction is D0 (128, 127).

It should be noted that the first transceiver T1, the second transceiver T2, the third transceiver T3, and the fourth transceiver T4 in each display device respectively follow the first direction, the second direction, and the third direction. The direction and the fourth direction sequentially trigger adjacent display devices until the endpoint display device, and when the transceivers trigger a predetermined time (eg, 2 seconds, but not limited thereto) in the respective corresponding directions When it is still found that there is no adjacent display device, the last display device that is not triggered to the adjacent display device is the endpoint display device.

Please refer to FIG. 1A and FIG. 2D. Step (S4): the endpoint display devices return the corresponding coordinate information to the initial display device; and (S5): the initial display device according to the first coordinate information and the corresponding coordinate information Calculate the size of the matrix. As shown in FIG. 2D, at this time, the endpoint display device D0 starts to transmit the corresponding coordinate information set by itself to the initial display device D1 along the original path. After the microprocessor of the starting display device D1 receives the corresponding coordinate information of the upper end display device D0, the matrix size of the entire TV splicing wall can be determined.

Briefly, in this embodiment, the first coordinate information of the starting display device D1 is D1 (128, 128), and the endpoints of the display device in the first direction, the second direction, the third direction, and the fourth direction are The corresponding coordinate information is D0 (130, 128), D0 (128, 129), D0 (127, 128), and D0 (128, 127). According to this, the microprocessor of the starting display device D1 can know that the number of rows of the entire matrix is 4, and the number of columns is 3, that is, the TV splicing wall is a 3x4 matrix.

Please refer to FIG. 1A and FIG. 2E. This embodiment mainly corrects the first coordinate information assumed at the beginning and corrects it to an absolute coordinate to make the setting of the subsequent television video wall more convenient and fast. Step (S6): the microprocessor of the initial display device is based on the pairs returned Resetting the first coordinate information to a second coordinate information, the second coordinate information is an absolute coordinate; and step (S7): the initial display device is along the first direction, the second direction, The third direction and the fourth direction sequentially transmit the second coordinate information to the adjacent display device, so that the microprocessors of the adjacent display devices reset the corresponding coordinate information. As shown in FIG. 2E, the microprocessor of the initial display device D1 resets the first coordinate information D1 (128, 128) to the second coordinate information D1' according to the corresponding coordinate information of the other display devices received in the previous step. , 1), the second coordinate information is an absolute coordinate.

Referring to FIG. 2E, the initial display device D1' sequentially transmits the second coordinate information D1'(1, 1) to the adjacent display device in the first direction, the second direction, the third direction, and the fourth direction, respectively. The display device that receives the second coordinate information automatically resets the coordinate information corresponding to the display device. For example, the display device D' automatically corrects its coordinate information to D'(1+1,1) according to the first coordinate information D1'(1,1), that is, D'(2,1); The endpoint display device D0 in one direction automatically corrects its own coordinate information to D0'(1+2,1) according to the first coordinate information D1'(1,1), that is, D0'(3,1). Similarly, the coordinate information of the endpoint display device D0' in the second direction is corrected to D0'(1,1+1), that is, D0'(1,2); the endpoint display device D0' in the third direction The coordinate information will be corrected to D0'(1-1,1), which is D0'(0,1); the coordinate information of the endpoint display device D0' in the fourth direction will be corrected to D0'(1,1- 1), which is D0' (1, 0).

However, at this time, only the initial display device D1 ′ and the coordinate information of the adjacent display device in the first direction to the fourth direction with the starting point are corrected, but other display devices have not yet set the corresponding absolute coordinate information. . In this embodiment, the absolute coordinates corresponding to the adjacent display devices that are not set with absolute coordinates are selectively provided by their transceivers through the display device that has set the absolute coordinates (ie, step (S8)). There are two main ways to set it up.

For example, referring to FIG. 1B and FIG. 2F, the step (S81): the display devices receiving the coordinate information by the first transceiver or the third transceiver are the second transceiver and the fourth The transceiver provides absolute coordinates corresponding to respective adjacent display devices that do not have absolute coordinates set. That is, the display device that receives the coordinate information by the first transceiver T1 or the third transceiver T3, that is, the display device in the first direction or the third direction, starting from D1', respectively, is respectively transmitted and received by the second transceiver. The T2 and the fourth transceiver T4 provide their own absolute coordinate information to adjacent display devices that do not set absolute coordinate information.

As seen from FIG. 2F, D0'(0, 1) respectively provides corresponding absolute coordinates to adjacent display devices through the second transceiver T2 and the fourth transceiver T4, namely D0'(0, 2) and D0' (0). , 0); D' (2, 1) respectively provide corresponding absolute coordinates to the adjacent display devices through the second transceiver T2 and the fourth transceiver T4, namely D0' (2, 2) and D0' (2, 0) D0'(3,1) respectively provides corresponding absolute coordinates to adjacent display devices through the second transceiver T2 and the fourth transceiver T4, namely D0'(3,2) and D0'(3,0).

The second mode, as shown in FIG. 1B and FIG. 2G, the step (S82): the display devices receiving the coordinate information by the second transceiver or the fourth transceiver are configured by the first transceiver and the The third transceiver provides absolute coordinates corresponding to respective adjacent display devices that do not have absolute coordinates set. That is, the display device that receives the coordinate information by the second transceiver T2 or the fourth transceiver T4, that is, the display device in the second direction or the fourth direction starting from D1', respectively, is respectively the first The transceiver T1 and the third transceiver T3 provide their own absolute coordinate information to adjacent display devices that do not set absolute coordinate information.

As shown in FIG. 2G, D0'(1, 2) respectively provides corresponding absolute coordinates to the adjacent display devices through the first transceiver T1 and the third transceiver T3, that is, D0'(0, 2), D0' (2) , 2) and D0' (3, 2). Similarly, D0' (1, 0) is respectively provided through the first transceiver T1 and the third transceiver T3. The absolute coordinates should be given to adjacent display devices, namely D0'(0,0), D0'(2,0) and D0'(3,0).

In another embodiment of the present invention, a video source is preferably coupled to the plurality of display devices, and the video source outputs the video screen to the plurality of display devices, and according to the setting method, the video information is based on the corresponding coordinate information. A corresponding divided screen is displayed on a plurality of display devices, wherein the divided screen is related to the video screen. The related information means that the resolution, size, and the like of the divided screen may be different from the video screen.

As shown in FIG. 4A, the first display device M1 and the other display devices form a television video wall in a matrix arrangement. The third transceiver T3 of the first display device M1 receives the corresponding coordinate information of the adjacent display device M0, that is, M0 (127, 128). The display device M0 sets the first display device M1 with its own coordinate information M0 (127, 128). At this time, the first display device M1 obtains the first corresponding coordinate information M1 (128, 127+1), that is, M1 (128, 128).

When the first transceiver T1 of the first display device M1 detects that there is an adjacent display device M, the display device M is set with the first corresponding coordinate information M1 (128, 128), and at the same time, the display device M obtains the corresponding coordinates. Information M (128+1, 128), ie M (129, 128). It should be noted that, similar to the foregoing embodiment, if the first transceiver T1 does not detect the neighbor within a predetermined time. When the device is displayed, the first corresponding coordinate information is returned through the third transceiver T3, that is, the step (S41).

Step (S5): the third transceiver receives an absolute coordinate information of the adjacent display device and sets the first display device as the absolute coordinate information; and step (S6): the second transceiver and the fourth The transceiver provides absolute coordinates corresponding to respective adjacent display devices that do not have absolute coordinates set. As shown in FIG. 4B, mainly similar to the correction means of the foregoing embodiment, the third transceiver T3 of the first display device M1' receives the absolute coordinate information M0' (0, 1) of the adjacent display device M0'. The absolute coordinate information of the first display device M1' is set to M1' (1, 1).

Next, please continue to refer to FIG. 4B. The first display device M1' sets the adjacent display device that does not set the absolute coordinate information through the second transceiver T2 and the fourth transceiver T4. As shown, the first display device M1' provides the second direction. The adjacent display device M0' has a corresponding absolute coordinate information M0' (1, 2), and similarly, a corresponding absolute coordinate information M0' (0, 1) of the adjacent display device M0' in the fourth direction is also provided.
