The specific structure and the pitch of the LED light emitting units are not particularly limited in the embodiments of the present invention, and for convenience of description, the embodiments of the present invention are exemplarily described based on the above structure.
Fig. 1 is a schematic structural diagram of an interposer and an LED display module according to an embodiment of the present invention. As shown in fig. 1, the LED display module 10 includes a signal receiving connector 11, a driving chip 13 and an LED light emitting unit 12, wherein the signal receiving connector 11 is electrically connected to the LED light emitting unit 12 through the driving chip 13; the adapter board 20 includes a receiving card 22 and two signal transmission connectors 211 and 212, the receiving card 22 is electrically connected with the signal transmission connectors 211 and 212, respectively; wherein, the signal transmission connectors 211 and 212 can be plugged with the signal receiving connector 11 in the forward direction or the reverse direction.
For example, the signal receiving connector 11 may be fixed to one side edge of the LED display module 10 by soldering, so as to electrically connect the signal receiving connector 11 with the LED light emitting unit 12 through the driving chip 13. If the signal receiving connector 11 of the LED display module 10 is inserted into the signal transmission connector 211 of the adapter plate 20 in the forward direction, after the LED display module 10 is rotated by 180 degrees, the signal receiving connector 11 of the LED display module 10 can be inserted into the signal transmission connector 212 of the adapter plate 20 in the reverse direction; on the contrary, if the signal receiving connector 11 of the LED display module 10 is reversely plugged with the signal transmission connector 211 of the adapter plate 20, after the LED display module 10 is rotated by 180 degrees, the signal receiving connector 11 of the LED display module 10 can be plugged with the signal transmission connector 212 of the adapter plate 20 in the forward direction. For convenience of description, the signal receiving connector 11 of the LED display module 10 and the signal transmitting connector 211 of the adapter board 20 are configured to be plugged in a forward direction, and the signal receiving connector 11 of the LED display module 10 and the signal transmitting connector 212 of the adapter board 20 are configured to be plugged in a reverse direction.
When the LED lighting unit 12 is controlled to perform display, the display control signals received by the LED lighting unit have differences. The receiving card 22 of the adapter board 20 receives the video data signal and converts the video data signal into a corresponding display control signal, and transmits the display control signal to the signal receiving connector 11 through the signal transmitting connector 211 or 212; the signal receiving connector 11 inputs each display control signal to each LED light emitting unit 12 through the driving chip, respectively, to drive the corresponding LED light emitting unit to display.
After the LED display module 10 is manufactured, the connection relationship between the signal receiving connector 11 and the driving chip 13 is determined, the connection mode between each signal output pin of the driving chip 13 and the LED light emitting unit 12 is fixed, and the connection mode between the receiving card 22 of the adapter board and the signal transmission connectors 211 and 212 of the adapter board is fixed after the adapter board 20 is manufactured. Therefore, the receiving card 22 of the adapter board 20 receives the video data signal and converts the video data signal into the display control signal corresponding to each LED lighting unit 12.
The receiving card 22 of the adapter board 20 has a signal processing module 221, which is configured to generate a forward display control signal when the signal receiving connector 11 is plugged in the signal transmitting connector 211 in the forward direction, and send the forward display control signal to the signal receiving connector 11 through the signal transmitting connector 211 so as to control the LED light-emitting unit 12 to display; alternatively, when the signal receiving connector 11 is reversely plugged into the signal transmitting connector 212, the signal processing module 221 generates a reverse display control signal, and sends the reverse display control signal to the signal receiving connector 11 through the signal transmitting connector 212 to control the LED lighting unit 12 to display.
When the signal receiving connector 11 of the LED display module 10 is plugged in the signal transmission connector 211 of the adapter board 20 in the forward direction, the signal processing module 221 of the receiving card 22 in the adapter board 20 can convert the video data signal into a forward display control signal corresponding to each LED light-emitting unit 12, and transmit the forward display control signal to each LED light-emitting unit through the signal transmission connector 211 and the signal receiving connector 11 which are plugged in the forward direction, so that each LED light-emitting unit displays; when the signal receiving connector 11 of the LED display module 10 is reversely plugged into the signal transmission connector 212 of the adapter board 20, the signal processing module 221 of the receiving card 22 in the adapter board 20 can convert the video data signal into a reverse display control signal, the reverse display control signal cannot directly control the corresponding LED light emitting unit 12 to display, and when the reverse display control signal is converted into a forward display control signal through the signal transmission connector 212 and the signal receiving connector 11 which are reversely plugged and is input into the corresponding LED light emitting unit 12, the LED light emitting unit 12 normally displays.
Therefore, when the LED display module 10 and the adapter plate 20 are assembled, the direction of the LED display module 10 does not need to be considered, so that the installation and maintenance efficiency can be improved, and the labor cost can be reduced; meanwhile, only one signal receiving connector 11 is arranged in the LED display module 10, and the position of the signal receiving connector 11 in the LED display module 10 does not need to be considered, so that the cost can be reduced, and the production efficiency can be improved.
Optionally, the signal transmission connector may include at least two first power signal pins; the first power signal pins are positioned on the first end face of the signal transmission connector, and the at least two first power signal pins are in symmetrical relation on the first end face; the signal transmission connector further comprises a signal transmission pin, and the signal transmission pin can be used for transmitting a forward display control signal or a reverse display control signal to the signal receiving connector.
Correspondingly, the signal receiving connector comprises at least two second power supply signal pins; the second power signal pins have a symmetrical relationship at a second end face of the signal receiving connector; the plurality of second power signal pins can be inserted with the plurality of first power signal pins of the signal transmission connector in a forward direction or a reverse direction; the signal receiving connector also comprises signal receiving pins, and each signal receiving pin can be used for receiving the forward display control signal or the reverse display control signal transmitted by each signal transmitting pin. The LED light-emitting unit emits light according to the forward display control signal or the reverse display control signal, so that the display module displays corresponding information.
It should be noted that the signal transmission connector includes at least two first power signal pins, and the corresponding signal reception connector includes at least two second power signal pins, that is, the number of the first power signal pins in the signal transmission connector may be 2 or more, and the number of the second power signal pins in the signal reception connector is also 2 or more.
For example, fig. 2 is a schematic structural diagram of a connector according to an embodiment of the present invention. As shown in fig. 2, the first terminal of the signal transmission connector 21 includes 2 first power signals VCC1 and VCC2, and in order to prevent the short circuit of the positive and negative insertion power, VCC1 and VCC2 have a symmetrical relationship with respect to the first terminal, the symmetrical relationship including central symmetry; accordingly, the second end face of the signal receiving connector 11 includes 2 second power signal pins VCC1 'and VCC2', and in order to prevent the short circuit of the positive and negative insertion power, VCC1 'and VCC2' have a symmetrical relationship with respect to the second end face, the symmetrical relationship including central symmetry. Meanwhile, the signal transmission connector 21 may further include 12 signal transmission pins 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and the signal reception connector 11 includes 12 signal reception pins 1', 2', 3', 4', 5', 6', 7', 8', 9', 10', 11', 12'.
When the signal transmission connector 21 is plugged with the signal receiving connector 11 in the forward direction, the two first power signals VCC1 and VCC2 of the signal transmission connector 21 are plugged with the 2 second power signal pins VCC1 'and VCC2' of the signal receiving connector 11 in a one-to-one correspondence manner, that is, the first power signal pin VCC1 is plugged with the second power signal pin VCC1', and the first power signal pin VCC2 is plugged with the second power signal pin VCC 2'. At this time, the forward display control signals generated by the signal processing module of the receiving card may respectively correspond to the first power signal pins VCC1 and VCC2, so that the signal transmission pins 1 to 12 of the signal transmission connector 21 transmit forward display control signals con1, con2, con3, con4, con5, con6, con7, con8, con9, con10, con11, con12, and the signal reception pins 1 'to 12' of the signal reception connector can respectively transmit the forward display control signals con1, con2, con3, con4, con5, con6, con7, con8, con9, con10, con11, con12 to the corresponding LED lighting units to control the display of the corresponding LED lighting units.
When the signal transmission connector 21 is reversely plugged with the signal receiving connector 11, the two first power signal pins VCC1 and VCC2 of the signal transmission connector 21 are plugged with the 2 second power signal pins VCC2 'and VCC1' of the signal receiving connector 11 in a one-to-one correspondence manner, that is, the first power signal pin VCC1 is plugged with the second power signal pin VCC2', and the first power signal pin VCC2 is plugged with the second power signal pin VCC 1'. At this time, the reverse display control signals generated by the signal processing module of the receiving card may respectively correspond to the first power signal pins VCC1 and VCC2, so that the signal transmission pins 1 to 12 of the signal transmission connector 21 transmit the forward display control signals con1, con2, con3, con4, con5, con6, con7, con8, con9, con10, con11, con12, and the signal reception pins 12 'to 1' of the signal reception connector can respectively transmit the forward display control signals con1, con2, con3, con4, con5, con6, con7, con8, con9, con10, con11, con12 to the corresponding LED lighting units to control the display of the corresponding LED lighting units. Thus, when the signal receiving connector 11 is plugged in the reverse direction, the display control signals received by the signal receiving pins 1 'to 12' are the same as the display control signals received when the signal receiving connector 11 is plugged in the forward direction, and the signal receiving pins 1 'to 12' distribute the received display control signals to the corresponding LED light-emitting units, so that the LED light-emitting units can normally display the display signals.
Optionally, the interposer may further include a detection pin, and the detection pin is electrically connected to the signal transmission connector; when the signal receiving connector and the signal transmission connector are inserted in a forward direction or a reverse direction, the detection pins receive first detection signals or second detection signals, and the signal processing module acquires the first detection signals or the second detection signals of the detection pins and correspondingly generates forward display control signals or reverse display control signals.
Correspondingly, the LED display module further comprises a marking pin, and the marking pin is electrically connected with the signal receiving connector; when the signal receiving connector and the signal transmission connector are inserted in a forward direction or a reverse direction, the marking pin sends a first type of electric signals or a second type of electric signals to the detection pin so that the detection pin receives the first detection signals or the second detection signals. In order to ensure that the marking pins can still be inserted into the detection pins after the LED display module rotates 180 degrees, the number of the marking pins is at least 2.
The detection pins of the adapter plate can be directly arranged on the adapter plate, and can also be arranged on other modules of the adapter plate, for example, the detection pins are arranged on a signal transmission connector of the adapter plate; similarly, the marking pins of the LED display module may be directly disposed on the LED display module, or may be disposed on other modules of the LED display module, such as a signal receiving connector for disposing the marking pins on the LED display module. The embodiment of the present invention is not particularly limited to this. The following description is made by way of example with reference to the accompanying drawings.
Illustratively, with continued reference to fig. 2, the detection pins of the interposer 20 are disposed on the signal transmission connector 21, i.e., the signal transmission connector 21 includes two detection pins DET1 and DET2, and correspondingly, the marking pins of the LED display module 10 are disposed on the signal receiving connector 11, i.e., the signal receiving connector 11 includes two marking pins DET1 'and DET2', respectively. The detection pin DET1 is electrically connected to the flag pin DET1 'and the detection pin DET2 is electrically connected to the flag pin DET2' when the signal receiving connector 11 is plugged in the forward direction with the signal transmitting connector 21, while the detection pin DET2 is electrically connected to the flag pin DET1 'and the detection pin DET1 is electrically connected to the flag pin DET2' when the signal receiving connector 11 is plugged in the reverse direction with the signal transmitting connector 21. If the flag pin DET1 'is a high-level flag signal and the flag pin DET2' is a low-level flag signal, when the signal receiving connector 11 is plugged into the signal transmitting connector 21 in the forward direction, the detection pin DET1 receives the high-level signal and the detection pin DET2 receives the low-level signal, and at this time, the signal processing module directly obtains the first detection signals of the detection pin DET1 and the detection pin DET2 and generates a forward display control signal; when the signal receiving connector 11 is reversely plugged into the signal transmitting connector 21, the detection pin DET1 receives a low level signal, the detection pin DET2 receives a high level signal, and the signal processing module directly obtains the second detection signals of the detection pin DET1 and the detection pin DET2 and generates a reverse display control signal.
Therein, the two detection pins DET1 and DET2 of the signal transmission connector 21 and the two flag pins DET1 'and DET2' of the signal reception connector 11 have a symmetrical relationship, which may be, for example, central symmetrical and/or axial symmetrical.
