Fig. 1 is a schematic diagram of a screen system 10 according to an embodiment of the present disclosure. In the present embodiment, the screen system 10 includes a main screen 20, at least one secondary screen 30, and a controller 100.
In the present embodiment, the primary screen 20 and the secondary screen 30 both have a first vertical side SD1 and a second vertical side SD2 on different sides. Specifically, when the first vertical side SD1 is the left side of the primary screen 20 and the secondary screen 30, the second vertical side SD2 is the right side of the primary screen 20 and the secondary screen 30. Also, when the first vertical side SD1 is the right side of the primary screen 20 and the secondary screen 30, the second vertical side SD2 is the left side of the primary screen 20 and the secondary screen 30. In other words, the direction from the center of the primary screen 20 to the first vertical side SD1 of the primary screen 20 is substantially the same as the direction from the center of the secondary screen 30 to the first vertical side SD1 of the secondary screen 30 (from right to left as viewed in fig. 1), and the direction from the center of the primary screen 20 to the second vertical side SD2 of the primary screen 20 is substantially the same as the direction from the center of the secondary screen 30 to the second vertical side SD2 of the secondary screen 30 (from left to right as viewed in fig. 1).
In the present embodiment, the main screen 20 and the sub-screen 30 are arranged side by side and face the respective display screens in the same direction. That is, the display screens of the primary screen 20 and the secondary screen 30 can be viewed substantially simultaneously for the same user.
In the present embodiment, the wireless transceiver 22 is disposed at the first vertical side SD1 of the primary screen 20, and the wireless transceiver 32 is disposed at the second vertical side SD2 of each secondary screen 30. That is, the wireless transceiver 22 and the wireless transceiver 32 are respectively disposed at different vertical sides of the primary screen 20 and the secondary screen 30. In the present embodiment, the wireless transceiver 22 and the wireless transceiver 32 can transmit wireless signals with substantially the same power, but the present invention is not limited thereto.
In the present embodiment, the controller 100 may be disposed on the main screen 20, on the sub-screen 30, or disposed externally independently of the main screen 20 and the sub-screen 30. In different embodiments, the controller 100 may be disposed on different devices, for example, a portion of the controller 100 may be disposed on the main screen 20, another portion of the controller 100 may be disposed on the sub-screen 30, and the rest may be disposed on a center console (not shown). That is, a part of the controller 100 may be an element having a calculation function on the main screen 20 and/or the sub-screen 30. In one embodiment, the controller 100 communicates with the primary screen 20 and/or the secondary screen 30 in a wired or wireless manner. In one embodiment, the controller 100 can be implemented by one or more Central Processing Units (CPUs), one or more microprocessors, one or more Programmable Logic Devices (PLDs), and/or one or more field-programmable gate arrays (FPGAs), but is not limited thereto.
In the present embodiment, the wireless transceiver 22 and the wireless transceiver 32 respectively receive wireless signals from each other. The controller 100 can obtain the signal strength of the wireless signals received by the wireless transceiver 22 and the wireless transceiver 32, and estimate the distance between the wireless transceiver 22 and the wireless transceiver 32 accordingly. Based on the distance between the wireless transceiver 22 and the wireless transceiver 32, the controller 100 can determine the arrangement relationship between the primary screen 20 and the secondary screen 30. In this way, the controller 100 can control the main screen 20 and the sub-screen 30 to display the image signals according to the arrangement relationship between the main screen 20 and the sub-screen 30.
By such an arrangement, inconvenience of a user in manually setting the arrangement relationship between the main screen 20 and the sub-screen 30 or manually arranging the positions of the main screen 20 and the sub-screen 30 can be reduced.
Various embodiments will be provided below to explain details of the present disclosure, but the present disclosure is not limited thereto.
Refer to fig. 2 to 4. In the present embodiment, the number of the sub-screens 30 is 1. In step B1, the wireless transceivers 22 and 32 are turned on and transmit wireless signals at approximately the same power. In one embodiment, the wireless transceiver 22 and the wireless transceiver 32 can be turned on according to user operation, user command, or command from other devices, but not limited thereto.
In step B2, the controller 100 receives a wireless signal from one of the wireless transceivers 22, 32 through the other wireless transceiver 22, 32, and obtains the signal strength of the wireless signal. The controller 100 estimates the distance between the wireless transceiver 22 and the wireless transceiver 32 according to the signal strength.
In step B3, the controller 100 determines whether the distance between the wireless transceiver 22 and the wireless transceiver 32 is less than a predetermined distance threshold. If so, the controller 100 may determine that the secondary screen 30 is adjacent to the first vertical side SD1 of the primary screen 20 (the arrangement relationship SB1) (see fig. 3). If not, the controller 100 may determine that the secondary screen 30 is adjacent to the second vertical side SD2 of the primary screen 20 (the arrangement relationship SB2) (refer to fig. 4). In one embodiment, the predetermined distance threshold may be set according to actual requirements. In one embodiment, the predetermined distance threshold may be set corresponding to the horizontal length of the primary screen 20 and the secondary screen 30.
Thus, the controller 100 can control the main screen 20 and the sub-screen 30 to display the image signals according to the arrangement relationship between the main screen 20 and the sub-screen 30.
Refer to fig. 5 to 11. In the present embodiment, the number of the sub-screens 30 is 2, that is, the at least one sub-screen 30 includes a sub-screen 30a (having the wireless transceiver 32a disposed thereon) and a sub-screen 30b (having the wireless transceiver 32b disposed thereon).
In step R1, the wireless transceivers 22, 32a, 32b are turned on and caused to transmit wireless signals at approximately the same power. In one embodiment, the wireless transceivers 22, 32a, 32b can be turned on according to user operation, user command, or command from other devices, but not limited thereto.
In step R2, the controller 100 receives wireless signals from the wireless transceivers 32a and 32b via the wireless transceiver 22, and obtains signal strengths of the wireless signals. In addition, the controller 100 receives the wireless signal from the wireless transceiver 32b through the wireless transceiver 32a, and obtains the signal strength of the wireless signal. The controller 100 estimates the distance between the wireless transceiver 22 and the wireless transceivers 32a, 32b according to the signal strengths. It should be noted that, in various embodiments, the controller 100 may estimate the distance between the wireless transceiver 22 and the wireless transceivers 32a and 32b through the signal strength received by different ones of the wireless transceivers 22, 32a and 32b, and the present disclosure is not limited to the above embodiments.
In step R3, the controller 100 determines whether the distance between the wireless transceiver 22 and the wireless transceiver 32a (also referred to as the second distance) is less than a first predetermined distance threshold. If yes, go to step R4; if not, go to step R5. In one embodiment, the first predetermined distance threshold may be set according to actual requirements. In one embodiment, the first predetermined distance threshold may be set corresponding to the horizontal lengths of the main screen 20 and the sub-screens 30 (i.e., the sub-screens 30a and 30 b); in the same manner, the controller 100 may alternatively determine the distance between the wireless transceiver 22 and the wireless transceiver 32b, which is equally effective.
In step R4, the controller 100 determines whether the distance between the wireless transceiver 32a and the wireless transceiver 32b (also referred to as the first distance) is greater than a second predetermined distance threshold. If so, the controller 100 may determine that the arrangement relationship from left to right is the secondary screen 30a, the primary screen 20 and the secondary screen 30b (arrangement relationship SR1) (see fig. 6). If not, the controller 100 may determine that the arrangement relationship from left to right is the secondary screen 30b, the secondary screen 30a and the primary screen 20 (arrangement relationship SR2) in sequence (see fig. 7). In one embodiment, the second predetermined distance threshold may be set according to actual requirements. In one embodiment, the predetermined distance threshold may be set corresponding to the horizontal length of the primary screen 20 and the secondary screen 30. In one embodiment, the second predetermined distance threshold is greater than the first predetermined distance threshold.
In step R5, the controller 100 determines whether the distance (i.e., the second distance) between the wireless transceiver 22 and the wireless transceiver 32a is greater than a second predetermined distance threshold. If yes, go to step R6; if not, go to step R7.
In step R6, the controller 100 determines whether the distance between the wireless transceiver 22 and the wireless transceiver 32b (also referred to as the third distance) is less than a first predetermined distance threshold. If so, the controller 100 can determine that the arrangement relationship from left to right is the secondary screen 30a, the secondary screen 30b and the primary screen 20 (arrangement relationship SR3) in sequence (see fig. 8). If not, the controller 100 may determine that the arrangement relationship from left to right is the main screen 20, the secondary screen 30b, and the secondary screen 30a (arrangement relationship SR4) in order (see fig. 9).
In step R7, the controller 100 determines whether the distance between the wireless transceiver 22 and the wireless transceiver 32b (i.e., the third distance) is greater than a second predetermined distance threshold. If so, the controller 100 may determine that the arrangement relationship from left to right is the main screen 20, the sub-screen 30a, and the sub-screen 30b (the arrangement relationship SR5) in sequence (see fig. 10). If not, the controller 100 may determine that the arrangement relationship from left to right is the secondary screen 30b, the primary screen 20, and the secondary screen 30a (arrangement relationship SR6) (see fig. 11).
Thus, the controller 100 can control the main screen 20 and the sub-screens 30a and 30b to display the image signals according to the arrangement relationship between the main screen 20 and the sub-screens 30a and 30 b.
It should be noted that, in various embodiments, the manner of comparing the first distance, the second distance, and the third distance with the first predetermined distance threshold and the second predetermined distance threshold may be adjusted according to actual needs, and the present disclosure is not limited to the above operation.
Referring to fig. 12 to 14, in the present embodiment, the number of the sub-screens 30 is 3, that is, the at least one sub-screen 30 includes a sub-screen 30a having a wireless transceiver 32a disposed thereon, a sub-screen 30b having a wireless transceiver 32b disposed thereon, and a sub-screen 30c having a wireless transceiver 32c disposed thereon. It should be noted that although the arrangement relationship between the main screen 20 and the sub-screens 30a and 30b in fig. 13 to 14 is illustrated as the arrangement relationship SR5 in fig. 10, the present disclosure is not limited thereto.
In the present embodiment, the controller 100 can first determine the arrangement relationship between the primary screen 20 and the secondary screens 30a and 30b by the method shown in the previous embodiment. Then, the controller 100 can determine the relative positions between the secondary screen 30c and the main screen 20 and the secondary screens 30a, 30b through the following steps G1-G4.
In step G1, the controller 100 turns off the wireless transceivers of the screens arranged between the leftmost and rightmost screens according to the arrangement relationship between the main screen 20 and the sub-screens 30a, 30 b. For example, under the arrangement SR5, the wireless transceiver 32a of the secondary screen 30a may be turned off; under the ranking relationship SR1, the wireless transceiver 22 of the home screen 20 may be turned off.
In step G2, the wireless transceiver 32c may be turned on to transmit wireless signals at approximately the same power as two of the wireless transceivers 22, 32a, 32b that are turned on.
In step G3, the controller 100 receives the wireless signal from the wireless transceiver 32c via the two wireless transceivers 22, 32a, and 32b that are turned on, respectively, and obtains two signal strengths corresponding to the wireless signal, respectively.
In step G4, the controller 100 compares the signal strength of the two signals, and when the signal strength of the wireless signal received by the wireless transceiver of the left screen is greater than the signal strength of the wireless signal received by the wireless transceiver of the right screen, the controller 100 determines that the secondary screen 30c is located on the left side of the main screen 20 and the secondary screens 30a and 30b (see fig. 13) (arrangement relationship SG 1). When the signal strength of the wireless signal received by the wireless transceiver of the left screen is smaller than the signal strength of the wireless signal received by the wireless transceiver of the right screen, the controller 100 determines that the secondary screen 30c is located on the right side of the primary screen 20 and the secondary screens 30a and 30b (see fig. 14) (arrangement SG 2).
Thus, the controller 100 can control the main screen 20 and the sub-screen 30 to display the image signals according to the arrangement relationship between the main screen 20 and the sub-screen 30.
In addition, in a similar way, the controller 100 can determine the arrangement relationship of the screens when more screens are added to the screen system 10.
The screen splicing method of fig. 15 will be combined to provide more detailed embodiments, but the embodiments are not limited to the embodiments.
It should be noted that this screen splicing method can be applied to a screen system having the same or similar structure as that shown in fig. 1. For simplicity, the screen splicing method will be described below by taking the screen system 10 in fig. 1 as an example according to an embodiment of the invention, but the invention is not limited to this application.
In addition, it should be understood that, the operations of the screen splicing method mentioned in the present embodiment, except for the sequence specifically described, can be performed simultaneously or partially simultaneously, with the sequence being adjusted according to actual needs.
Moreover, operations may be adaptively added, replaced, and/or omitted in various embodiments.
Referring to fig. 1 and 15, the screen splicing method 200 includes the following operations.
In step S1, the wireless transceiver 22 is disposed on the first vertical side SD1 of the main screen 20.
In step S2, the wireless transceiver 32 is disposed on the second vertical side SD2 of the secondary screen 30.
In step S3, the primary screen 20 and the secondary screen 30 are arranged side by side with the respective display screens facing in the same general direction.
In step S4, the wireless transceivers 22, 32 transmit signals at approximately the same power.
In step S5, the controller 100 obtains the signal strength of the wireless transceiver 22 and the wireless transceiver 32 and estimates the distance between the wireless transceiver 22 and the wireless transceiver 32.
In step S6, the controller 100 determines the arrangement relationship between the primary screen 20 and the secondary screen 30 according to the distance between the wireless transceiver 22 and the wireless transceiver 32. In one embodiment, the controller 100 can compare the distance between the wireless transceiver 22 and the wireless transceiver 32 with a predetermined distance threshold to determine the alignment relationship between the primary screen 20 and the secondary screen 30. For details of this operation, reference is made to the above paragraphs corresponding to fig. 2, which are not repeated herein.
In another embodiment, the controller 100 can compare the distance between the wireless transceiver 22 and the wireless transceiver 32 with the first predetermined distance threshold and the second predetermined distance threshold to determine the arrangement relationship between the primary screen 20 and the secondary screen 30. In one embodiment, the controller 100 can select one of the sub-screens 30 (e.g., the sub-screen 30a) as the first sub-screen and select another one of the sub-screens 30 (e.g., the sub-screen 30b) as the second sub-screen to determine the first distance, the second distance and the third distance. For details of this operation, reference is made to the above paragraphs corresponding to fig. 5, which are not repeated herein.
In step S7, the controller 100 controls the main screen 20 and the sub-screen 30 to display image signals according to the arrangement relationship between the main screen 20 and the sub-screen 30. In one embodiment, the controller 100 determines the image data to be provided to the primary screen 20 and the secondary screen 30 according to the arrangement relationship between the primary screen 20 and the secondary screen 30, so that the primary screen 20 and the secondary screen 30 respectively display the corresponding pictures according to the arrangement relationship.
It should be noted that the details of the operations in the above method can all refer to the above paragraphs, which are not repeated herein.
By the above operation, the inconvenience of the user manually setting the arrangement relationship between the main screen 20 and the sub-screen 30 or manually arranging the positions of the main screen 20 and the sub-screen 30 can be reduced.
On the other hand, in some embodiments, after determining the arrangement relationship between the primary screen 20 and the secondary screens 30, if the number of the secondary screens 30 is more than 2, the screen splicing method 200 may further include the following steps T1-T4 to add a new secondary screen to the screen system 10.
The following steps T1-T4 are described with reference to fig. 13 and 14, but the present disclosure is not limited thereto.
In step T1, the secondary screen 30c can be selectively placed on one side of the main screen 20, the secondary screen 30a and the secondary screen 30b in any arrangement combination, and the display screen of the secondary screen 30c faces in the same direction as the display screen of the main screen 20.
In step T2, the wireless transceiver 32c may be disposed on the second vertical side SD2 of the secondary screen 30 c. For details of this operation, reference is made to the above paragraphs, which are not repeated here.
In step T3, the wireless transceiver of the screen arranged between the leftmost and rightmost screens of the main screen 20, the sub-screen 30a and the sub-screen 30b (in this case, the wireless transceiver 32a of the sub-screen 30a) may be turned off according to the arrangement relationship between the main screen 20, the sub-screen 30a and the sub-screen 30 b. In one embodiment, the wireless transceiver can be turned off according to user operation, user command, or command from other devices, but not limited thereto.
In step T4, the controller 100 obtains the signal strength of the wireless signal of the wireless transceiver 32c of the sub-screen 30c by the wireless transceivers arranged on the leftmost and rightmost screens (in this case, the wireless transceiver 22 of the main screen 20 and the wireless transceiver 32b of the sub-screen 30b), respectively, and determines the end with stronger signal strength as the arrangement position of the sub-screen 30 c. For example, when the signal strength of the wireless signal received by the wireless transceiver of the leftmost screen is greater than the signal strength of the wireless signal received by the wireless transceiver of the rightmost screen, the controller 100 determines that the secondary screen 30c is located on the left side of the main screen 20 and the secondary screens 30a and 30b (see fig. 13). When the signal strength of the wireless signal received by the wireless transceiver of the leftmost screen is less than the signal strength of the wireless signal received by the wireless transceiver of the rightmost screen, the controller 100 determines that the secondary screen 30c is located on the right side of the main screen 20 and the secondary screens 30a and 30b (see fig. 14).
Thus, when a new sub-screen is added to the screen system 10, the controller 100 still determines the arrangement position of the new sub-screen.
In summary, the screen splicing method provided by the present invention includes: arranging a first wireless transceiver on a first vertical side of a main screen; arranging at least one second wireless transceiver on a second vertical side of the at least one secondary screen; the main screen and the at least one secondary screen are arranged side by side, and the respective display screens face the same direction; the first wireless transceiver and the at least one second wireless transceiver transmit signals with the same power; obtaining signal strength of the first wireless transceiver and the at least one second wireless transceiver and estimating a distance between the first wireless transceiver and the at least one second wireless transceiver; judging the arrangement relation between the main screen and the at least one secondary screen according to the distance; and displaying the image signal according to the arrangement relation.
