[0038] The terminal multiplexing driving circuit and the method, and the display system provided by the present application only require two communication terminals for each driving circuit group: a multiplexing terminal and a back-reading terminal, thereby reducing the requirement for the number of communication terminals of the controller; compared with the prior art which requires three communication terminals for each driving circuit group, the present application can drive more driving circuit groups for the same number of communication terminals of the controller; in summary, the cost of the driving circuit can be reduced.

DETAILED DESCRIPTION

[0051] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0054] In the description of the present application, the meaning of "a plurality of" is a plurality, for example, two, three, four, etc., unless otherwise explicitly specified and limited.

[0055] In the description of the specification of the present application, unless otherwise explicitly specified and limited, the terms "connection" and the like should be broadly understood, for example, it can be fixedly connected, or detachably connected, or integrated; it can be mechanically connected, or electrically connected or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship between two elements. For a person of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0056] The technical solutions of the present application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in some embodiments.

[0057] In an embodiment, a terminal multiplexing driving circuit is provided, which comprises a control circuit 1, a driving circuit group 2; the driving circuit group 2 comprises a plurality of driving circuits, please refer to Fig. 1. Wherein, in each driving circuit group 2: one of the driving circuits is a multiplexing driving circuit 21, the multiplexing driving circuit 21 and the rest of the driving circuits 22 are sequentially connected in series for communication. The control circuit 1 comprises a multiplexing terminal 11, a back-reading terminal 12. The multiplexing terminal is connected with the driving circuits for communication respectively; the back-reading terminal is connected with the last driving circuit 221 connected in series for communication. The multiplexing terminal 11 is used for outputting the serial communication signal of the control circuit 1 to transmit to the multiplexing driving circuit 21; the multiplexing terminal 11 is also used for outputting the parallel communication signal of the control circuit 1 to transmit to each driving circuit. The back-reading terminal 12 is used for transmitting the serial communication signal returned by the last driving circuit connected in series for communication back to the control circuit.

[0058] The serial communication signal can be used to realize, for example, the distribution of driving circuit address, the back-reading of state, etc., and the parallel communication signal can be used to realize, for example, the transmission of dimming data, etc.

[0059] The terminal multiplexing driving circuit of the above-mentioned embodiment of the present application reduces the number of terminals required by each row of driving circuits through terminal multiplexing of the control circuit and the design of the multiplexing driving circuit; the reduction of the number of terminals is in relation to the existing three terminals, and the three terminals can realize the transmission of serial communication signal and parallel communication signal. Through the above-mentioned embodiment of the present application, the transmission of serial communication signal and parallel communication signal can still be realized while reducing the number of terminals, and the transmission time required by the parallel communication signal is short.

[0060] Although there is also a two-terminal circuit design in the prior art, it can only realize the transmission of serial communication signal, and the back-reading of state and the transmission of dimming data all need to be transmitted in a serial manner, and for all communication data, the transmission time required is relatively long.

[0061] In an embodiment, please refer to Fig. 1, along the direction away from the control circuit, the driving circuits in each driving circuit group are sequentially distributed, i.e. the driving circuits with ID=1~N are sequentially distributed; the multiplexing driving circuit is the driving circuit with ID=1 in the corresponding driving circuit group, which is the closest to the control circuit.

[0062] In addition, along the direction away from the control circuit, the driving circuits in each driving circuit group are sequentially connected in series for communication, i.e. ID1~N are sequentially connected in series for communication, so that the last driving circuit connected in series for communication is the driving circuit farthest from the control circuit, and the arrow direction in the figure is the direction of signal transmission. The connection mode can save data transmission time, and the communication connection setting is consistent with the position setting, so it is easy to find the fault driving circuit.

[0063] In another embodiment, referring to FIG. 2, the driving circuits in each driving circuit group are sequentially distributed in the direction away from the control circuit, i.e., the driving circuits with ID = 1 ~ N are sequentially distributed; and the multiplexing driving circuit is the driving circuit with ID = N in the corresponding driving circuit group, which is the farthest from the control circuit.

[0064] In addition, the driving circuits in each driving circuit group are sequentially connected in series in communication in the direction away from the control circuit, i.e., the driving circuits with ID1 ~ N are sequentially connected in series in communication, so that the last driving circuit connected in series in communication is the driving circuit closest to the control circuit, and the arrow direction in the figure is the signal transmission direction. Using this connection mode can save data transmission time, and the communication connection setting is consistent with the position setting, so it is easy to find the fault driving circuit.

[0065] In different embodiments, a mixture of the above two connection modes can also be used. Referring to FIG. 3, the driving circuits in each driving circuit group are sequentially distributed in the direction away from the control circuit. The number of driving circuit groups is multiple, and part of the multiplexing circuits can be used as the driving circuit closest to the control circuit in the corresponding driving circuit group; and part of the multiplexing circuits can be used as the driving circuit farthest from the control circuit in the corresponding driving circuit group.

[0066] In FIG. 3, only an example is shown, and the first driving circuit group and the last driving circuit group are taken as examples. The first driving circuit group uses the driving circuit closest to the control circuit as the multiplexing driving circuit, and the last driving circuit group uses the driving circuit farthest from the control circuit as the multiplexing driving circuit. The remaining driving circuit groups are not shown, and appropriate driving circuits can be designed as multiplexing driving circuits according to needs.

[0067] Of course, in different embodiments, the first group and the last group do not necessarily use the above multiplexing driving circuit setting mode, and each driving circuit group can design appropriate driving circuits as multiplexing driving circuits according to needs.

[0068] It should be noted that the above embodiments are only preferred embodiments. In different embodiments, the serial communication connection order between the driving circuits in each driving circuit group can also not use the above rule (consistent with the position distribution), but can also use other connection orders, such as: the first one is connected to the third one, the third one is connected to the second one, and so on.

[0069] For signal identification between the multiplexing driving circuit and the multiplexing terminal, as an implementation manner, the multiplexing driving circuit itself can be used to achieve. Specifically, the control circuit only sends the serial communication signal and the parallel communication signal to the multiplexing driving circuit through the multiplexing terminal, and the multiplexing driving circuit identifies whether the received signal is a serial communication signal or a parallel communication signal, so as to perform corresponding serial communication operation and parallel communication operation.

[0070] For the multiplex drive terminal itself to achieve signal identification, as an embodiment, the terminal for receiving serial communication signals and the terminal for receiving parallel communication signals of the multiplex drive circuit can be different terminals, i.e. realized by two terminals, as shown in FIG. 1, 2, 3.

[0071] The terminal for receiving parallel communication signals is represented by DIP and the terminal for receiving serial communication signals is represented by DIS in FIG. 1, 2, 3.

[0072] For the multiplex drive circuit to realize signal receiving by two terminals, as an embodiment, one of the terminals (e.g. DIP) is set to only receive parallel communication signals and not receive serial communication signals, and the other terminal (e.g. DIS) is set to only receive serial communication signals and not receive parallel communication signals. Thus, it can be determined through the terminals whether the received signal is a serial communication signal or a parallel communication signal. When DIP receives a communication signal, it is a parallel communication signal and corresponding parallel communication operation is performed; when DIS receives a communication signal, it is a serial communication signal and corresponding serial communication operation is performed.

[0073] For the multiplex drive circuit to realize signal receiving by two terminals, as another embodiment, both terminals can be set to receive all communication signals, i.e. both terminals receive parallel communication signals and serial communication signals. At this time, it is impossible to identify through the terminals of the multiplex drive circuit whether the received signal is a serial communication signal or a parallel communication signal, which needs to be realized by the internal modules of the multiplex drive circuit.

[0074] For the multiplex drive terminal itself to achieve signal identification, as another embodiment, the terminal for receiving serial communication signals and the terminal for receiving parallel communication signals of the multiplex drive circuit can be the same terminal, i.e. the multiplex terminal 211 of the drive circuit, as shown in FIG. 4, 5, 6. At this time, it is impossible to identify through the terminals of the multiplex drive circuit whether the received signal is a serial communication signal or a parallel communication signal, which needs to be realized by the internal modules of the multiplex drive circuit.

[0075] When the terminal of the multiplexing driving circuit cannot identify whether the received signal is a serial communication signal or a parallel communication signal, as an embodiment, when the multiplexing terminal 211 of the driving circuit receives a communication signal, the signal identification module 201 can identify whether the received communication signal is a serial communication signal or a parallel communication signal, so as to perform corresponding operations, please refer to FIG. 7. When it is identified as a serial communication signal, the serial communication signal processing module 202 performs corresponding serial communication operation, and when it is identified as a parallel communication signal, the parallel communication signal processing module 203 performs corresponding parallel communication operation. Embodiment, the serial communication signal and the parallel communication signal adopt different command formats, and the signal identification module 201 can identify whether the received signal is a serial communication signal or a parallel communication signal through the command format.

[0076] It should be understood that in the above embodiment, the remaining driving circuit receives serial communication and parallel communication through two terminals as an example. In different embodiments, the remaining driving circuit can also receive communication signals through one terminal, which will not be described here.

[0077] For the signal identification between the multiplexing driving circuit and the multiplexing terminal, as another embodiment, the control circuit can be used to achieve. Specifically, after the driving circuit completes the address allocation, the control circuit can inform the corresponding multiplexing driving circuit through the multiplexing terminal whether to send a serial communication signal or a parallel communication signal, and the multiplexing driving circuit receives the communication signal according to the command of the control circuit to perform corresponding operation.

[0078] For the signal identification realized by the control circuit, as an embodiment, the control circuit can realize the transmission of the communication signal through two commands, such as: first send a command to inform the corresponding multiplexing driving circuit to be serial, and then send a serial communication signal; or, first send a command to inform the corresponding multiplexing driving circuit to be parallel, and then send a parallel communication signal.

[0079] For the signal identification realized by the control circuit, as another embodiment, the control circuit can also realize the transmission of the communication signal through one command, such as: a command includes a serial command and a serial communication command; or, a command includes a parallel command and a parallel communication command.

[0080] In an embodiment, a terminal multiplexing driving method is also provided, which comprises:

[0081] S11: transmission of serial communication signal; specifically, please refer to FIG. 8, which comprises:

[0082] S111: outputting the serial communication signal of the control circuit through the multiplexing terminal to the multiplexing driving circuit;

[0083] S112: the serial communication signal is transmitted to the multiplexing driving circuit of the driving circuit group, and then to the remaining driving circuits in sequence; wherein, the multiplexing driving circuit and the remaining driving circuits are connected in series in sequence;

[0084] When data needs to be read back, the method further comprises:

[0085] S113: the last driving circuit connected in series in sequence transmits the serial communication signal back to the control circuit;

[0086] S12: transmission of the parallel communication signal; specifically, the method comprises:

[0087] The parallel communication signal of the control circuit is outputted by using a multiplexing terminal and transmitted to each driving circuit.

[0088] In the above embodiments, S11 and S12 are not the execution order of two steps, and can be S11 first and then S12, or S12 first and then S11, or S11 and S12 can be performed simultaneously.

[0089] In an embodiment, when the serial communication signal or the parallel communication signal is transmitted to the multiplexing driving circuit, the method further comprises:

[0090] The multiplexing driving circuit identifies whether the received signal is a serial communication signal or a parallel communication signal.

[0091] In practice, the serial communication signal and the parallel communication signal can be identified by different command formats.

[0092] In an embodiment, when the serial communication signal of the control circuit is outputted by using a multiplexing terminal or the parallel communication signal of the control circuit is outputted by using a multiplexing terminal, the method further comprises:

[0093] The multiplexing terminal informs the multiplexing driving circuit whether the output is a serial communication signal or a parallel communication signal.

[0094] In an embodiment, a display system is also provided, which comprises: a light emitting element array and a terminal multiplexing driving circuit. The terminal multiplexing driving circuit is used to drive the light emitting element array, and each driving circuit corresponds to one light emitting element. The terminal multiplexing driving circuit is the terminal multiplexing driving circuit described in any of the above embodiments.

[0095] In practice, the light emitting element array can be an LED array.
