It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0055] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second", etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0056] like Figures 1 to 4 As shown, an embodiment of the present disclosure provides a display device 1, which may include at least two device structures 11, each of which may include a binding portion, and the binding portions of any two adjacent device structures 11 may be bound and connected to achieve electrical connection between the device structures 11. After the binding portions of any two adjacent device structures 11 are bound and connected, a binding resistor R1 is formed in a binding region 12 therebetween, and the resistance value of the binding resistor R1 may affect the performance of the display device 1, so that the resistance value of the binding resistor R1 needs to be accurately detected.

[0057] In some embodiments, Figure 2 As shown, the display device 1 may include three device structures 11, and the three device structures 11 may be a circuit board, a binding structure and a display panel respectively, and the circuit board, the binding structure and the display panel may all have a binding portion. The binding portion of the circuit board may be bound and connected to the binding portion of the binding structure on the side away from the display panel, and a binding resistor R1 may be formed in the binding area 12 between the circuit board and the binding structure. The binding portion of the display panel may be bound and connected to the binding portion of the binding structure on the side away from the circuit board, and a binding resistor R1 may be formed in the binding area 12 between the display panel and the binding structure. The circuit board and the display panel are electrically connected to each other through the binding connection of the binding structure, and signal data transmission may be performed between each other.

[0058] However, it is not limited thereto, and the display device 1 may also include other numbers of device structures 11 . For example, the display device 1 may also have two device structures 11 , four device structures 11 , five device structures 11 , etc., which may be selected and set according to actual needs.

[0059] In order to accurately and conveniently detect the binding resistor R1 in the display device 1, the inventor of the present disclosure invented a new display device 1, in which a resistance detection module 2 is provided. The resistance detection module 2 can improve the detection accuracy and simplicity of the binding resistor R1 in the display device 1.

[0060] In some embodiments, Figures 1 to 3 As shown, the resistance detection module 2 may include: a detection circuit 21. The detection circuit 21 may include: a first detection branch 211 and a second detection branch 212, the first detection branch 211 may be arranged on one of the device structures 11, and the second detection branch 212 may be arranged on any other device structure 11. The first detection branch 211 and the second detection branch 212 may be electrically connected to each binding part located therebetween, so as to detect the binding resistance R1 formed by each binding part located between the first detection branch 211 and the second detection branch 212 after the binding connection.

[0061] That is, it can be understood that, for example, the display device 1 may include three device structures 11, such as Figure 1 As shown, the first detection branch 211 can be set in the first device structure 11, and the second detection branch 212 can be set in the second device structure 11, so as to detect the binding resistance R1 formed by the binding part of the first device structure 11 and the second device structure 11 after the binding connection. Figure 2 As shown, the first detection branch 211 can be set in the first device structure 11, and the second detection branch 212 can be set in the third device structure 11, so as to detect the binding resistance R1 formed by the binding parts of the first device structure 11 and the second device structure 11 after the binding connection, and the sum of the binding resistance R1 formed by the binding parts of the second device structure 11 and the third device structure 11 after the binding connection, so as to obtain the total binding resistance R1 of the display device 1.

[0062] Therefore, the resistance detection module 2 in the display device 1 provided by the present disclosure can accurately detect the binding resistance R1 between the device structures 11 at different positions in the display device 1 without adding the detection circuit 21 and the detection points. At the same time, the total binding resistance R1 between different numbers of device structures 11 can be accurately detected without adding the circuit and the detection points. Therefore, the difficulty of detecting the binding resistance R1 in the display device 1 can be reduced, and the efficiency and accuracy of detecting the binding resistance R1 in the display device 1 can be improved.

[0063] In some embodiments, the resistance detection module 2 may further include: a transmission circuit 22. The transmission circuit 22 may include a first transmission branch 221 and a second transmission branch 222. The first transmission branch 221 may be arranged on one of the device structures 11, and the second transmission branch 222 may be arranged on any other device structure 11. The first transmission branch 221 and the second transmission branch 222 may be electrically connected to each binding portion located therebetween, so as to transmit data between the first transmission branch 221 and the second transmission branch 222. Thus, the resistance detection module 2 provided in the present disclosure can detect the binding resistor R1 in the display device 1 while taking into account the function of data signal transmission.

[0064] That is, it can be understood that, for example, the display device 1 may include three device structures 11, such as Figure 1 As shown, the first transmission branch 221 can be disposed in the first device structure 11, and the second transmission branch 222 can be disposed in the second device structure 11, so as to transmit data between the first device structure 11 and the second device structure 11. Alternatively, as Figure 2 As shown, the first transmission branch 221 may be disposed in the first device structure 11 , and the second transmission branch 222 may be disposed in the third device structure 11 , so as to transmit data between the first device structure 11 and the third device structure 11 .

[0065] In some embodiments, the first transmission branch 221 and the first detection branch 211 may be located in the same device structure 11, and the second transmission branch 222 and the second detection branch 212 may be located in the same device structure 11. For example, when the first detection branch 211 is located in the first device structure 11, the first transmission branch 221 may also be located in the first device structure 11; when the second detection branch 212 is located in the third device structure 11, the second transmission branch 222 may also be located in the third device structure 11.

[0066] The detection circuit 21 may be provided with a first switch 213, and the first switch 213 may be used to control the on and off of the detection circuit 21. When the first switch 213 is closed, the detection circuit 21 may detect the binding resistor R1; when the first switch 213 is opened, the detection circuit 21 will not detect the binding resistor R1. Thus, the detection circuit 21 may freely control the detection work of the binding resistor R1 by controlling the first switch 213 as needed.

[0067] The transmission circuit 22 may be provided with a second switch 223, and the second switch 223 may be used to control the on and off of the transmission circuit 22. When the second switch 223 is closed, the transmission circuit 22 may transmit data signals; when the second switch 223 is opened, the transmission circuit 22 does not transmit signals. Thus, the signal transmission work of the transmission circuit 22 may be freely controlled by controlling the second switch 223 as needed.

[0068] At the same time, since the detection circuit 21 and the transmission circuit 22 are both electrically connected to the binding part, the first switch 213 and the second switch 223 can be set to avoid the problem of short circuit between the detection circuit 21 and the transmission circuit 22, and the problem of mutual interference between the detection circuit 21 and the transmission circuit 22 can be avoided. Figure 1 and Figure 2 As shown, when the resistance detection module 2 needs to detect the binding resistor R1, the first switch 213 can be closed to turn on the detection circuit 21, and the second switch 223 can be opened to turn off the transmission circuit 22; Figure 3 As shown, when the resistance detection module 2 needs to be used to transmit a data signal, the first switch 213 can be opened to turn off the detection circuit 21 , and the second switch 223 can be closed to turn on the transmission circuit 22 .

[0069] Further, the first switch 213 may include a first sub-switch K1 and a second sub-switch K2, the first sub-switch K1 may be located in the first detection branch 211, and the second sub-switch K2 may be located in the second detection branch 212. The second switch 223 may include a third sub-switch K3 and a fourth sub-switch K4, the third sub-switch K3 may be located in the first transmission branch 221, and the fourth sub-switch K4 may be located in the second transmission branch 222. With such a configuration, the problem of short circuit between the detection circuit 21 and the transmission circuit 22 can be further avoided, and the problem of mutual interference between the detection circuit 21 and the transmission circuit 22 can be avoided.

[0070] In this embodiment, if Figure 1 and Figure 2 As shown, when the resistance detection module 2 needs to detect the binding resistor R1, the first sub-switch K1 and the second sub-switch K2 can be closed to turn on the detection circuit 21, and the third sub-switch K3 and the fourth sub-switch K4 can be opened to turn off the transmission circuit 22; Figure 3 As shown, when the resistance detection module 2 needs to be used to transmit a data signal, the first sub-switch K1 and the second sub-switch K2 can be opened to turn off the detection circuit 21, and the third sub-switch K3 and the fourth sub-switch K4 can be closed to turn on the transmission circuit 22.

[0071] In some embodiments, the binding portion may include a first sub-binding portion and a second sub-binding portion disposed adjacent to each other. The first end of the first detection branch 211 and the first end of the second detection branch 212 may be electrically connected to each first sub-binding portion located between the first detection branch 211 and the second detection branch 212. The second end of the first detection branch 211 and the second end of the second detection branch 212 may be electrically connected to each second sub-binding portion located between the first detection branch 211 and the second detection branch 212.

[0072] The first detection branch 211 may include: a first sub-detection branch and a second sub-detection branch. One end of the first sub-detection branch may be the first end of the first detection branch 211, and the other end of the first sub-detection branch may be the first voltage end; one end of the second sub-detection branch may be the second end of the first detection branch 211, and the other end of the second sub-detection branch may be the second voltage end. There may be two first sub-switches K1, and the two first sub-switches K1 may be located in the first sub-detection branch and the second sub-detection branch, respectively.

[0073] Alternatively, the second detection branch 212 may include: a third sub-detection branch 2121 and a fourth sub-detection branch 2122. Among them, one end of the third sub-detection branch 2121 may be the first end of the second detection branch 212, and the other end of the third sub-detection branch 2121 may be the first voltage end. One end of the fourth sub-detection branch 2122 may be the second end of the second detection branch 212, and the other end of the fourth sub-detection branch 2122 may be the second voltage end. There may be two second sub-switches K2, and the two second sub-switches K2 may be located in the third sub-detection branch 2121 and the fourth sub-detection branch 2122, respectively.

[0074] The present disclosure can be connected to a power source by setting a first voltage terminal and a second voltage terminal to power the resistance detection module 2. For example, the first voltage terminal can be connected to a first power source VCC, and the second voltage terminal can be grounded, but is not limited thereto.

[0075] In some embodiments, the detection circuit 21 may further include a matching resistor RS to ensure the accuracy of the detection circuit 21 in detecting the binding resistor R1, and to avoid the problem of a short circuit inside the detection circuit 21 due to the binding resistor R1 being too small. For example, the matching resistor RS may be set in any of the above-mentioned sub-detection branches.

[0076] The detection circuit 21 may further include: a resistance detection point S2, and the resistance value of the binding resistor R1 may be obtained by collecting the voltage of the resistance detection point S2. For example: the resistance detection point S2 may be set on any of the above-mentioned sub-detection branches.

[0077] The first transmission branch 221 may include: a first sub-transmission branch 2211 and a second sub-transmission branch 2212. The second transmission branch 222 may include: a third sub-transmission branch 2221 and a fourth sub-transmission branch 2222. Each sub-transmission branch may have a signal terminal S1 and a connection terminal, that is, the first sub-transmission branch 2211, the second sub-transmission branch 2212, the third sub-transmission branch 2221 and the fourth sub-transmission branch 2222 may have a signal terminal S1 and a connection terminal, the signal terminal S1 may be used to input or output a data signal, and the connection terminal may be used to connect a binding part.

[0078] The connection end of the first sub-transmission branch 2211 and the connection end of the third sub-transmission branch 2221 can be electrically connected to each first sub-binding portion located between the first transmission branch 221 and the second transmission branch 222. The connection end of the second sub-transmission branch 2212 and the connection end of the fourth sub-transmission branch 2222 are electrically connected to each second sub-binding portion located between the first transmission branch 221 and the second transmission branch 222. In this way, the transmission circuit 22 can form two signal transmission paths, that is, the first sub-transmission branch 2211, the first sub-binding portion and the third sub-transmission branch 2221 can constitute one signal transmission path, and the second sub-transmission branch 2212, the second sub-binding portion and the fourth sub-transmission branch 2222 can constitute a second signal transmission path.

[0079] Further, the second switch 223 may include: two third sub-switches K3 and two fourth sub-switches K4. The two third sub-switches K3 are respectively located in the first sub-transmission branch 2211 and the second sub-transmission branch 2212; the two fourth sub-switches K4 may be respectively located in the third sub-transmission branch 2221 and the fourth sub-transmission branch 2222. In this configuration, the two third sub-switches K3 and the two fourth sub-switches K4 may be used to control the on and off of the two signal transmission paths, and short circuits and signal interference between each sub-transmission branch and the detection circuit 21 may be further avoided.

[0080] In some embodiments, each device structure 11 may have multiple binding parts, and the binding parts of any two adjacent device structures 11 may be correspondingly bound and connected. For example, the first device structure 11 may have three binding parts, namely, a first binding part, a second binding part, and a third binding part, and the second device structure 11 may also have three binding parts, namely, a first binding part, a second binding part, and a third binding part. The first binding part of the first device structure 11 is correspondingly bound and connected to the first binding part of the second device structure 11, the second binding part of the first device structure 11 is correspondingly bound and connected to the second binding part of the second device structure 11, and the third binding part of the first device structure 11 is correspondingly bound and connected to the third binding part of the second device structure 11.

[0081] The resistance detection module 2 may have a plurality of detection circuits 21, and the plurality of detection circuits 21 correspond to the plurality of binding parts one by one. The first detection branch 211 and the second detection branch 212 of any detection circuit 21 are electrically connected to the corresponding binding parts, so as to detect the binding resistance R1 formed by the corresponding binding parts after the binding connection. For example, the first device structure 11 and the second device structure 11 both have three binding parts, namely, the first binding part, the second binding part and the third binding part. The detection circuit 21 may have a plurality of detection circuits, the first detection circuit 21 may be electrically connected to the first binding part of the first device structure 11 and the first binding part of the second device structure 11, the second detection circuit 21 may be electrically connected to the second binding part of the first device structure 11 and the second binding part of the second device structure 11, and the third detection circuit 21 may be electrically connected to the third binding part of the first device structure 11 and the third binding part of the second device structure 11. With such a configuration, the detection points of the detection circuit 21 may be increased to improve the detection range of the binding resistance R1 between the device structures 11 and improve the detection accuracy of the binding resistance R1 between the device structures 11.

[0082] The resistance detection module 2 may have a plurality of transmission circuits 22, and the plurality of transmission circuits 22 correspond to the plurality of binding parts one by one. The first transmission branch 221 and the second transmission branch 222 of any transmission circuit 22 are electrically connected to the corresponding binding parts, so as to transmit data between the first transmission branch 221 and the second transmission branch 222. For example, the first device structure 11 and the second device structure 11 each have three binding parts, namely, the first binding part, the second binding part and the third binding part. There may be a plurality of transmission circuits 22, the first transmission circuit 22 may be electrically connected to the first binding part of the first device structure 11 and the first binding part of the second device structure 11, the second transmission circuit 22 may be electrically connected to the second binding part of the first device structure 11 and the second binding part of the second device structure 11, and the third transmission circuit 22 may be electrically connected to the third binding part of the first device structure 11 and the third binding part of the second device structure 11.
