[0002] With the development of the electronics industry, display screens are increasingly used in education, security, medical treatment, commerce and other fields. Their production technology is very mature, with high product yield, relatively low production cost and high market acceptance. At present, the demand for various ultra-large display screens is increasing day by day, and their applications are becoming more and more extensive. Due to technological limitations, the integrated production process of ultra-large display screens is difficult and costly. Therefore, spliced ​​screens have become the only choice for ultra-large screen displays. Spliced ​​screens can not only combine multiple units into a large screen, but also use one of the units for separate display, which is highly flexible.

[0039] In view of the problems existing in the prior art, an embodiment of the present application provides a splicing screen, including a splicing controller 20 and a plurality of display units 10. The specific structure of the display unit 10 is as follows: Figure 1 As shown, Figure 2 As shown, the spliced ​​screen provided in this embodiment includes four display units 10 .

[0040] like Figure 1As shown, the display unit 10 is in a rectangular shape. The display unit 10 includes a wireless transmission module 101 and a left short-range wireless communication module 102, a right short-range wireless communication module 103, a top short-range wireless communication module 104, and a bottom short-range wireless communication module 105, respectively arranged at the left edge of the display unit 10, wherein the left short-range wireless communication module 102 and the top short-range wireless communication module 104 are respectively used to transmit a wireless signal carrying a unique identification code (such as ID information) of the display unit 10; the right short-range wireless communication module 103 is used to receive a wireless signal carrying a unique identification code of other display units 10 transmitted by the left short-range wireless communication module 102 of other display units 10, and the bottom short-range wireless communication module 105 is used to receive a wireless signal carrying a unique identification code of other display units 10 transmitted by the top short-range wireless communication module 104 of other display units 10; the unique identification code of each display unit 10 is, for example, ID information, such as marked as D01, D02, and D03.

[0041] In addition, the wireless transmission module 101 is used to determine the position information of other display units 10 adjacent to the display unit 10 and the unique identification code of other adjacent display units 10 according to the wireless signal received by the right short-range wireless communication module 103 and / or the lower short-range wireless communication module 105, and send the unique identification code of the display unit 10, the position information of other display units 10 adjacent to the display unit 10 and the unique identification code of other adjacent display units 10 to the splicing controller 20. The display unit of this embodiment is suitable for a splicing screen that uses 5G technology to transmit wireless signals, which can effectively improve the wireless signal transmission rate of the display unit.

[0042] In a specific example, if Figure 1 As shown, the unique identification code of the display unit 10 is ID information D01. The unique identification codes of other adjacent display units 10 may be ID information D02, D03, D04, etc. The left short-range wireless communication module 102 and the upper short-range wireless communication module 104 are respectively used to transmit wireless signals carrying ID information D01, while the right short-range wireless communication module 103 is used to receive wireless signals carrying ID information D02 transmitted by the left short-range wireless communication module 102 of other display units 10 (e.g., display units 10 with ID information D02), and the lower short-range wireless communication module 105 is used to receive wireless signals carrying ID information D03 transmitted by the upper short-range wireless communication module 104 of other display units 10 (e.g., display units with ID information D03).

[0043] The wireless transmission module 101 determines the position information of other display units 10 adjacent to the display unit 10 according to the wireless signal received by the short-range wireless communication module 103 on the right side (for example, Figure 1-2 The display unit D02 located on the right side of the display unit D01 as shown) and the unique identification codes (ID information D02) of other adjacent display units 10, and the unique identification code (ID information D01) of the display unit 10, the position information of other display units 10 adjacent to the display unit 10 (located on the right side of the display unit D01) and the unique identification codes (ID information D02) of other adjacent display units 10 are sent to the splicing controller 20;

[0044] The wireless transmission module 101 determines the position information of other display units 10 adjacent to the display unit 10 (for example, Figure 1-2 The display unit D03 located below the display unit D01 as shown in the figure and the unique identification codes (ID information D03) of other adjacent display units 10, and the unique identification code (ID information D01) of the display unit 10, the orientation information of other display units 10 adjacent to the display unit 10 (located on the lower side of the display unit D03) and the unique identification codes (ID information D03) of other adjacent display units 10 are sent to the splicing controller 20.

[0045] In another specific example, the right short-range wireless communication module 103 and the lower short-range wireless communication module 104 are respectively used to transmit wireless signals carrying the unique identification code (such as ID information) of the display unit 10; and the left short-range wireless communication module 102 is used to receive the wireless signal carrying the unique identification code of other display units 10 transmitted by the right short-range wireless communication module 103 of other display units 10, and the upper short-range wireless communication module 104 is used to receive the wireless signal carrying the unique identification code of other display units 10 transmitted by the lower short-range wireless communication module 105 of other display units 10.

[0046] The splicing controller 20 is used to identify and locate each display unit according to the unique identification code of the display unit received from the display unit 10, the position information of other display units 10 adjacent to the display unit 10, and the unique identification codes of the other adjacent display units 10. The splicing controller 20 includes a processor 201, a display 202, and a wireless transmission module 203.

[0047] Since the video inputs of each display unit 10 are independent of each other, the overall display control of the spliced ​​screen is implemented by the splicing controller 20, and the video signal can be divided based on the equal division mode of rectangular splicing. The main function of the splicing controller 20 is to divide the input overall video signal into regional video signals corresponding to each display unit 10. The main basis for completing this process is the recognition and positioning results of each display unit 10.

[0048] In making Figure 2 When the splicing screen shown is working, firstly, the power of the splicing controller 20 is turned on, and the processor 201, the display 202 and the wireless transmission module 203 of the splicing controller 20 are all started, and then each display unit 10 in the splicing screen is powered on one by one, and each display unit 10 presets its own unique identification code (for example, ID information D01, D02, D03), and then sends its own unique identification code to the splicing controller 20 through the wireless transmission module 101 of each display unit 10;

[0049] Subsequently, the splicing controller 20 receives the unique identification codes sent by each display unit 10 through its own wireless transmission module 203, and organizes the information through the processor 201, and then displays the unique identification codes of each display unit 10 on the display 202 for verification by on-site personnel. For example, the ID information of the first display unit 10 received by the splicing controller 20 is marked as D01, and the ID information of the second display unit 10 received subsequently is marked as D02, and so on;

[0050] In a specific example, if Figure 2 The workflow of the splicing screen shown is as follows:

[0051] First, when the short-range wireless communication module 103 on the right side of the display unit D01 is flush with the short-range wireless communication module 102 on the left side of the display unit D02 (i.e., the distance is within 0-20 mm), the wireless signal carrying the unique identification code (ID information D01) of the display unit 10 transmitted by the short-range wireless communication module 103 on the right side of the display unit D01 is received by the short-range wireless communication module 102 on the left side of the display unit D02, that is, the display unit D01 and the display unit D02 are paired and connected. At the same time, the wireless transmission module 101 of the display unit D02 determines the orientation information of the display unit D01 and the display unit D02 (located on the left side of the display unit D02) and the unique identification code of the display unit D01 according to the wireless signal received from the display unit D01 by the short-range wireless communication module 102 on the left side of the display unit 10, and sends the unique identification codes of the display units D01 and D02 and the orientation information of the display units D01 and D02 to the splicing controller 20. Similarly, the short-distance wireless communication module 105 below the display unit D01 and the short-distance wireless communication module 104 above the display unit D03 are paired and connected in the same way. Figure 1 When the splicing is done into a grid, the display 202 of the splicing controller 20 displays the following: Figure 1 Style shown.

[0052] Subsequently, after the wireless transmission module 203 of the splicing connector 20 receives the unique identification code from each display unit 10 and the orientation information of the adjacent display unit 10, the processor 201 of the splicing connector 20 realizes the identification and positioning of each display unit 10, and then divides the picture data according to the identification and positioning results, and precodes the divided picture data for each display unit 10 respectively, and then sends the processed data information to the wireless transmission module 101 of each display unit 10 through the wireless transmission module 203 of the splicing controller 20.

[0053] Finally, after each display unit 10 receives the data information from the splicing controller 20 through its own wireless transmission module 101, it obtains its own digital information by decoding its own corresponding unique identification code. Then, each display unit 10 converts the obtained digital information through its own display screen and displays the assigned picture on the display screen to realize wireless splicing display.

[0054] Based on the display units 10 in the spliced ​​screen provided by this embodiment, the splicing controller 20 can accurately and conveniently identify and locate each display unit 10 in the spliced ​​screen. At the same time, multiple display units 10 are allowed to be assembled in any order and in any orientation, which can effectively reduce the splicing workload and difficulty of the splicing screen, improve the assembly convenience and troubleshooting efficiency of the splicing screen, and achieve the purpose of fast and easy assembly of the splicing screen through wireless splicing; furthermore, the wireless display of each display unit 10 can be realized. The splicing controller 20 can send the segmented display data to the wireless transmission modules 101 of each display unit 10 in the splicing screen through wireless communication, thereby eliminating the need to connect the display units with network cables to realize the transmission of image data between the display units, thereby avoiding the low assembly efficiency and easy connection errors caused by the splicing connection of multiple display units through data cables and network cables.

[0055] In some specific embodiments, such as Figure 1-2 As shown, the short-range wireless communication module 102 on the left side and the short-range wireless communication module 104 on the top of the display unit 10 are infrared transmitters, respectively, and the short-range wireless communication module 103 on the right side and the short-range wireless communication module 105 on the bottom are infrared receivers, respectively. This embodiment uses an infrared transmitter to transmit a flashing infrared light signal to the infrared receiver, and the flashing infrared light signal can carry binary data, such as ID information, that is, the unique identification code of this display unit. When the infrared transmitter of this display unit is flush with and close to the infrared receiver of other display units (that is, the distance between the infrared transmitter and the infrared receiver of other display units is 0-20mm), the infrared receivers of other display units receive the infrared light signal emitted by the infrared transmitter of this display unit, and the infrared transmitter and the infrared receiver complete the pairing connection.

[0056] This embodiment uses an infrared transmitter and an infrared receiver, which can be applied to a variety of different industrial environments, such as high voltage, radiation, toxic gas, dust and other environments. It not only effectively improves the reliability of wireless signal connection but also can effectively isolate electrical interference; and the infrared transmitter has strong communication directionality, which improves the working efficiency of the short-range wireless communication module and avoids interference from other signals.

[0057] In some specific implementations, the left short-range wireless communication module 102 and the upper short-range wireless communication module 104 of the display unit 10 are RFID electronic tags, and the right short-range wireless communication module 103 and the lower short-range wireless communication module 105 are RFID readers. This embodiment can set the sensing range of different types of RFID electronic tags such as passive, semi-active, active RFID and RFID electronic tags according to the size of the display unit.

[0058] In a specific example, the above-mentioned RFID electronic tag is a passive RFID for close-range contact identification. The passive RFID realizes information exchange by receiving microwave signals transmitted by the RFID reader and obtaining energy through the electromagnetic induction coil to briefly power itself, while eliminating the power supply system. The passive RFID product is smaller in size, which can reach the centimeter level or even smaller, with a low failure rate and a long service life. It is suitable for scenarios where the display unit is small and the effective identification distance required for RFID is short. In another specific example, the RFID electronic tag may be a semi-active RFID electronic tag. The semi-active RFID electronic tag first uses a low-frequency signal for precise positioning, and then uses a high-frequency signal to quickly transmit data. It is suitable for scenarios where the display unit is large and the effective identification distance required for RFID is long.

[0059] In this embodiment, by using RFID electronic tags, the RFID recognition distance can be freely adjusted according to the size of the display unit, and signal penetration and barrier-free reading can be achieved. At the same time, the RFID electronic tag has a huge storage capacity, allowing each display unit to have a unique identifier; and the RFID electronic tag has strong resistance to substances such as water, oil and chemicals. It can adapt to various working environments and working conditions.

[0060] In some specific implementations, the short-range wireless communication modules on the top, bottom, left, and right sides of the display unit 10 are NFC chips, respectively.

[0061] In a specific example, the right short-range wireless communication module 102 and the upper short-range wireless communication module 104 are NFC master devices, and the left short-range wireless communication module 103 and the lower short-range wireless communication module 105 are NFC slave devices. Figure 2 As shown, the right NFC master device of the display unit 10 with ID information D03 provides a radio frequency field through the energy of the power supply device, and transmits the ID information D03 to the left NFC slave device of the display unit 10 with ID information ID04; the upper NFC master device of the display unit 10 with ID information D03 provides a radio frequency field through the energy of the power supply device, and transmits the ID information D03 to the lower NFC slave device of the display unit 10 with ID information D01, so that the left NFC slave device of the display unit 10 with ID information D04 and the lower NFC slave device of the display unit 10 with ID information D01 receive the ID information D03 through the right NFC master device and the upper NFC master device of the display unit 10 with ID information D03.

[0062] In another specific example, the short-range wireless communication modules on the top, bottom, left and right sides of the display unit 10 are all NFC integrated transceiver devices, that is, the NFC integrated transceiver devices on the top and right sides of the display unit 10 with ID information D03 respectively transmit the ID information D03 to the NFC integrated transceiver device on the left side of the display unit 10 with ID information 04 and the NFC integrated transceiver device below the display unit 10 with ID information D01. At the same time, the NFC integrated transceiver device on the top of the display unit 10 with ID information D03 receives the ID information D01 transmitted by the NFC integrated transceiver device below the display unit 10 with ID information D01, and the NFC integrated transceiver device on the right side of the display unit 10 with ID information D03 receives the ID information 04 transmitted by the NFC integrated transceiver device on the left side of the display unit 10 with ID information 04.

[0063] In this implementation, by using an NFC chip, a one-receive-one-transmit or a transceiver-in-one working mode can be selected, further improving the pairing speed and accuracy of the short-range wireless communication module, while ensuring the transmission security and endurance of the short-range wireless communication module.

[0064] In some specific implementations, in order to meet some specific touch usage scenarios, the display unit 10 further includes a touch module 106, such as Figure 3-4 As shown, the wireless transmission module 101 is also used to send the touch operation information carrying the unique identification code of the display unit 10 to the splicing controller 20. Specifically, according to the coordinate information of the touch module 106 on the display unit 10, the user's touch point can be accurately located. When the user touches the display unit 10 and needs to feedback the touch result, the unique identification code of the display unit 10 carried by the touch module 106 and the coordinate data of the touch module 106 are sent to the splicing controller 20 through the wireless transmission module 101. After the splicing controller 20 receives the unique identification code and coordinate data of the display unit 10, the splicing controller 20 processes the coordinate data and locates the pixel area of ​​the corresponding segmented screen, thereby executing the program after the touch. For example, the updated screen is fed back to the corresponding display unit 10 through the splicing controller 20 and displayed.

[0065] For the above-mentioned embodiment, the display unit 10 may be independently provided with a wireless transmission module for sending the touch operation information carrying the unique identification code of the display unit 10 to the splicing controller 20 .

[0066] The display unit 10 can realize the touch function of the display unit 10 by configuring the touch module 106, improve the operability of the display unit 10, and further realize the multifunctional application of the spliced ​​screen.

[0067] In an embodiment of the splicing screen in which the display unit 10 includes a touch module 106, when a user touches a certain display unit 10, the touch module 106 of the display unit 10 generates coordinate data, such as D01-XY, and the wireless transmission module 101 of the display unit 10 sends the touch operation information carrying the unique identification code of the display unit 10 including the coordinate data to the splicing controller 20. The processor 201 of the splicing controller 20 processes the coordinate data, accurately locates the touch point according to the coordinate data, and then finds the corresponding pixel area of ​​the screen, so as to proceed to the next step, such as updating the screen according to the touch result, and then transmitting it back to the corresponding display unit 10 through the signal module to realize the touch function of the splicing screen.

[0068] Another embodiment of the present application provides a splicing screen, including a splicing controller 20 and a plurality of display units 10. The specific structure of the display unit 10 is as follows: Figure 1 As shown, Figure 2 As shown, the spliced ​​screen provided in this embodiment includes four display units 10.

[0069] like Figure 1-4 As shown, the display unit 10 is rectangular in shape. Different from the display unit 10 in the aforementioned embodiment, in the display unit 10 of this embodiment, the left short-range wireless communication module 102 is used to transmit a wireless signal carrying a unique identification code (e.g., ID information) of the left short-range wireless communication module 102, and the upper short-range wireless communication module 104 is used to transmit a wireless signal carrying a unique identification code (e.g., ID information) of the upper short-range wireless communication module 104; the right short-range wireless communication module 103 is used to receive a wireless signal carrying a unique identification code of the left short-range wireless communication module 102 of other display units transmitted by the short-range wireless communication module 102 on the left side of other display units, and the lower short-range wireless communication module 105 is used to receive the upper short-range wireless communication module 104 of other display units. If the right short-range wireless communication module 103 or the lower short-range wireless communication module 105 can receive the wireless signal carrying the unique identification code of the upper short-range wireless communication module 104 of other display units transmitted by the left short-range wireless communication module 102 or the upper short-range wireless communication module 104 of other display units, then the right short-range wireless communication module 103 or the lower short-range wireless communication module 105 can be paired and connected with the left short-range wireless communication module 102 or the upper short-range wireless communication module 104 of other display units.

[0070] In a specific example, if Figure 5-6As shown, the display unit 10 itself is preset with a unique identification code (e.g., ID information, e.g., marked as D01, D02, D03); and the short-range wireless communication modules on the left, right, top, and bottom sides are each preset with a unique identification code according to their different positions (e.g., the ID information of the upper short-range wireless communication module 104 is marked as D01-U, the ID information of the lower short-range wireless communication module 105 is marked as D01-D, the ID information of the left short-range wireless communication module 102 is marked as D01-L, and the ID information of the right short-range wireless communication module 103 is marked as D01-R).

[0071] In addition, the wireless transmission module 101 is used to determine the unique identification code 104 of the left short-range wireless communication module 102 and / or the upper short-range wireless communication module of other display units 10 adjacent to the present display unit 10 based on the wireless signals received by the right short-range wireless communication module 103 and / or the lower short-range wireless communication module 105, and send the unique identification code of the present display unit 10, the unique identification code of the right short-range wireless communication module 103 and / or the lower short-range wireless communication module 105 of the present display unit 10, and the unique identification code of the left short-range wireless communication module 102 and / or the upper short-range wireless communication module 104 of other display units 10 adjacent to the present display unit 10 to the splicing controller 20.

[0072] Since in this embodiment, the short-range wireless communication modules on the left, right, top and bottom sides each have a unique identification code, so that the pairing connection between each short-range wireless communication module has a directionality, the splicing controller can list the position connection status of each display unit based on this, that is, the splicing controller determines the connection status between the two display units based on the pairing status of the short-range wireless communication module of this display unit and the short-range wireless communication module of other display units, and displays it to the operator through the display of the splicing controller. When all the display units 10 are spliced, the splicing controller 20 divides the input picture according to the splicing status of the display unit 10, and then pre-encodes the data information of the divided picture and returns it to each display unit 10. Each display unit 10 receives the pre-encoded data information of the divided picture and decodes it to obtain its own data information, converts the data information into picture information through its own display screen, and displays its own part to complete the splicing and enlarged display.

[0073] In a specific example, the right short-range wireless communication module 103 and the lower short-range wireless communication module 105 are respectively used to transmit wireless signals carrying unique identification codes (such as ID information) of their respective short-range wireless communication modules; and the left short-range wireless communication module 102 is used to receive wireless signals carrying the unique identification codes of the right short-range wireless communication modules 103 of other display units 10 transmitted by the right short-range wireless communication modules 103 of other display units 10, and the upper short-range wireless communication module 104 is used to receive wireless signals carrying the unique identification codes of the lower short-range wireless communication modules 105 of other display units 10 transmitted by the lower short-range wireless communication modules 105 of other display units 10.

[0074] The splicing controller 20 is used to identify and locate each display unit according to the unique identification code of the display unit 10 received from the display unit 10 and the unique identification code of the left short-range wireless communication module 102 and / or the upper short-range wireless communication module 104 of other display units 10 adjacent to the display unit 10. The splicing controller 20 includes a processor 201, a display 202 and a wireless transmission module 203.

[0075] In making Figure 2 When the splicing screen shown is working, firstly, the power of the splicing controller 20 is turned on, and the processor 201, display 202 and wireless transmission module 203 of the splicing controller 20 are all started, and then each display unit 10 in the splicing screen is powered on one by one, and each display unit 10 presets its own unique identification code (for example, ID information D01, D02, D03), the short-range wireless communication module 102 on the left and the short-range wireless communication module 104 on the top preset their own unique identification codes (for example, D01-Tx-L, D01-Tx-U), and the short-range wireless communication module 102 on the right and the short-range wireless communication module 104 on the bottom preset their own unique identification codes (for example, D01-Rx-R, D01-Rx-D). Then the wireless transmission module 101 of the display unit 10 sends the unique identification code of the display unit 10 and the unique identification codes of each short-range wireless communication module to the splicing controller 20.

[0076] Subsequently, the splicing controller 20 receives the unique identification code of each display unit 10 and the unique identification code of each short-range wireless communication module sent by each display unit 10 through its own wireless transmission module 203, and organizes the information through the processor 201, and then displays the unique identification code of each display unit 10 and its respective short-range wireless communication module on the display 202 for verification by on-site personnel. For example, the ID information of the first display unit 10 received by the splicing controller 20 is marked as D01, and the ID information of the short-range wireless communication modules corresponding to its upper, lower, left and right sides are marked as D01-Tx-U, D01-Rx-D, D01-Rx-L, and D01-Tx-R, respectively. Similarly, the ID information of the second display unit 10 subsequently received is marked as D02, and the ID information of the short-range wireless communication modules corresponding to its upper, lower, left and right sides are marked as D02-Tx-U, D02-Rx-D, D02-Rx-L, and D02-Tx-R, and so on;

[0077] In a specific example, if Figure 2 The workflow of the splicing screen shown is as follows:

[0078] First, when the short-distance wireless communication module 103 (D01-Tx-R) on the right side of the display unit D01 is flush with the short-distance wireless communication module 102 (D02-Rx-L) on the left side of the display unit D02 (i.e., the distance is within 0-20 mm), the wireless signal transmitted by the short-distance wireless communication module 103 on the right side of the display unit D01 and carrying the unique identification code of the display unit (ID information D01) and the ID information (D01-Tx-R) of the short-distance wireless communication module 103 on the right side of the display unit D02 is received by the short-distance wireless communication module 102 on the left side of the display unit D02, and the display unit D01 and the display unit D02 are connected. Unit D02 is paired and connected, and at the same time, the wireless transmission module 101 of the display unit D02 determines the unique identification code of the display unit D01 and the right short-range wireless communication module 103 paired therewith according to the wireless signal received by the left short-range wireless communication module 102 of the display unit 10 from the display unit D01, and sends the unique identification code of the display units D01 and D02 and the unique identification code of the left short-range wireless communication module 102 of the display unit 10 and the right short-range wireless communication module 103 paired therewith of other display units 10 to the splicing controller 20. Similarly, several other short-range wireless communication modules of the display unit D01 and the short-range wireless communication modules of other display units 10 are paired and connected in the same way. When the four display units of this embodiment are as shown in FIG. Figure 1 When the splicing is done into a grid, the display 202 of the splicing controller 20 displays the following: Figure 1 The relative position of each display unit 10 is determined by the unique identification code of the short-range wireless communication module on each display unit 10.

[0079] Subsequently, after the splicing connector 20 receives the unique identification code from each display unit 10 and its short-range wireless communication module and the orientation information of the adjacent display unit 10, the processor 201 realizes the identification and positioning of each display unit 10, and then divides the picture data according to the identification and positioning results, and precodes the divided picture data for each display unit 10 respectively, and then sends the processed data information to the wireless transmission module 101 of each display unit 10 through the wireless transmission module 203 of the splicing controller 20.

[0080] Finally, after each display unit 10 receives the data information from the splicing controller 20 through its own wireless transmission module 101, it decodes and obtains its own digital information according to its own corresponding unique identification code. Then, each display unit 10 converts the obtained digital information through its own display screen and displays the assigned picture on the display screen to realize wireless splicing display.

[0081] In the splicing screen provided in another embodiment of the present application, respective unique identification codes are set for respective short-range wireless communication modules in the display units 10, so that the splicing controller 20 can further accurately and conveniently identify and locate the orientation information between the respective display units in the splicing screen, thereby improving the identification and positioning efficiency of the splicing work.

[0082] In some specific embodiments, such as Figure 1 As shown, the left short-range wireless communication module 102 and the upper short-range wireless communication module 104 of the display unit 10 are infrared transmitters, and the right short-range wireless communication module 103 and the lower short-range wireless communication module 105 are infrared receivers.

[0083] This embodiment uses an infrared transmitter to transmit a flashing infrared light signal to an infrared receiver. The flashing infrared light signal can carry binary data, such as ID information, that is, the unique identification code of the short-range wireless communication module. When the infrared transmitter of this display unit is flush with and close to the infrared receiver of other display units (that is, the distance between the infrared transmitter and the infrared receiver of other display units is 0-20mm), the infrared receiver of the other display unit receives the wireless signal transmitted by the infrared transmitter of this display unit and carrying the unique identification code of the infrared transmitter, thereby achieving pairing connection.

[0084] It should be noted that the technical effects of the infrared transmitter and infrared receiver provided in this embodiment are similar to those of the infrared transmitter and infrared receiver in the other embodiment mentioned above. The relevant details can be referred to the above description and will not be repeated here.

[0085] In some specific implementations, the left short-range wireless communication module 102 and the upper short-range wireless communication module 104 are RFID electronic tags, and the right short-range wireless communication module 103 and the lower short-range wireless communication module 105 are RFID readers. This embodiment can set the sensing range of different types of RFID electronic tags such as passive, semi-active, active RFID and RFID electronic tags according to the size of the display unit.

[0086] In a specific example, the RFID electronic tag is a passive RFID for close-range contact identification. The passive RFID achieves information exchange by receiving microwave signals transmitted from the RFID reader and obtaining energy through an electromagnetic induction coil to briefly power itself, while eliminating the power supply system. The passive RFID product is smaller in size, which can reach the centimeter level or even smaller, with a low failure rate and a long service life. It is suitable for scenarios where the display unit is small and the effective identification distance required for RFID is short. In another specific example, the RFID electronic tag may be a semi-active RFID electronic tag. The semi-active RFID electronic tag first uses a low-frequency signal for precise positioning, and then uses a high-frequency signal to quickly transmit data. It is suitable for scenarios where the display unit is large and the effective identification distance required for RFID is long.

[0087] It should be noted that the technical effects of the RFID electronic tag and RFID reader provided in this embodiment are similar to those of the RFID electronic tag and RFID reader in the above-mentioned other embodiment. The relevant parts can be referred to the above description and will not be repeated here.

[0088] In some specific implementations, the upper, lower, left, and right short-range wireless communication modules are NFC chips respectively.

[0089] In a specific example, the right short-range wireless communication module 102 and the upper short-range wireless communication module 104 are NFC master devices, and the left short-range wireless communication module 103 and the lower short-range wireless communication module 105 are NFC slave devices.

[0090] For example, Figure 2As shown, the right NFC master device of the display unit 10 with ID information D03 provides a radio frequency field through the energy of the power supply device, and transmits ID information D03-Tx-R to the left NFC slave device of the display unit 10 with ID information ID04; the upper NFC master device of the display unit 10 with ID information D03 provides a radio frequency field through the energy of the power supply device, and transmits ID information D03-Tx-U to the lower NFC slave device of the display unit 10 with ID information D01, so that the left NFC slave device of the display unit 10 with ID information D04 receives the ID information D03-Tx-R through the right NFC master device of the display unit 10 with ID information D03; the lower NFC slave device of the display unit 10 with ID information D01 receives the ID information D03-Tx-U through the upper NFC master device of the display unit 10 with ID information D03.

[0091] In another specific example, the short-range wireless communication modules on the upper, lower, left and right sides of the display unit 10 are all NFC transceiver integrated devices, that is,

[0092] The NFC integrated transceiver devices on the upper and right sides of the display unit 10 with ID information D03 transmit ID information D03-R and ID information D03-U to the NFC integrated transceiver device on the left side of the display unit 10 with ID information 04 and the NFC integrated transceiver device below the display unit 10 with ID information D01, respectively. At the same time, the NFC integrated transceiver device on the upper side of the display unit 10 with ID information D03 receives the ID information D01-D transmitted by the NFC integrated transceiver device below the display unit 10 with ID information D01, and the NFC integrated transceiver device on the right side of the display unit 10 with ID information D03 receives the ID information D04-L transmitted by the NFC integrated transceiver device on the left side of the display unit 10 with ID information 04.

[0093] It should be noted that the technical effect of the NFC chip provided in this embodiment is similar to that of the NFC chip in the other embodiment mentioned above. The relevant details can be referred to the above description and will not be repeated here.

[0094] In a specific implementation, in order to meet some specific touch usage scenarios, the display unit 10 further includes a touch module 106, such as Figure 3-4As shown, the wireless transmission module 101 is also used to send the touch operation information carrying the unique identification code of the touch module 106 to the splicing controller 20. Specifically, the touch module 106 of each display unit 10 corresponds to a unique identification code (such as ID information, such as marked as D01-TP), and the display unit 10 area where the touch point is located can be determined according to the unique identification code of different touch modules 106. According to the coordinate information of the touch module 106 on the display unit 10 (for example, marked as D01-TP-XY), the user's touch point can be accurately located. When the user touches the display unit 10 and needs to feedback the touch result, the unique identification code of the touch module 106 carried by the touch module 106 and the coordinate data of the touch module 106 are sent to the splicing controller 20 through the wireless transmission module 101 of the display unit 10. After receiving the unique identification code and coordinate data of the touch module 106, the splicing controller 20 processes the coordinate data and locates the pixel area corresponding to the segmented image, thereby executing the program after the touch control. For example, the updated image is fed back to the corresponding display unit 10 through the splicing controller 20 and displayed.

[0095] For the above-mentioned implementation, the display unit 10 may be independently provided with a wireless transmission module for sending the touch operation information carrying the unique identification code of the touch module 106 to the splicing controller 20 .

[0096] The display unit 10 can realize the touch function of the display unit 10 by configuring the touch module 106, improve the operability of the display unit 10, and further realize the multifunctional application of the spliced ​​screen.

[0097] In the embodiment of the splicing screen in which the display unit 10 includes the touch module 106, when the splicing screen pairing connection is completed, the unique identification code of the touch module 106 of each display unit 10 will also be sent to the splicing connector 20, and the splicing connector 20 will sort out the received unique identification code of the touch module 106. Figure 3-4 As shown, for example, the unique identification code of the touch module 106 of the display unit D01 is marked as D01-TP, and the unique identification codes of the touch modules 106 of the other display units 10 are marked as D02-TP, D03-TP, and D04-TP respectively.

[0098] When a user touches a display unit 10, the touch module 106 of the display unit 10 generates coordinate data, such as Dxx-TP-XY. The wireless transmission module 101 of the display unit 10 sends the touch operation information including the coordinate data carrying the unique identification code of the display unit 10 and its touch module 106 to the splicing controller 20. The processor 201 of the splicing controller 20 processes the coordinate data, roughly determines the touch point area through the unique identification code of the touch module 106, and accurately locates the touch point according to the coordinate data Dxx-TP-XY, and then finds the corresponding screen pixel area, so as to proceed to the next step, such as updating the screen according to the touch result, and then transmitting it back to the corresponding display unit through the signal module to realize the touch function of the splicing screen.

[0099] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not limitations on the implementation methods of the present application. For ordinary technicians in this field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present application are still within the scope of protection of the present application.
