[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] It should be noted that, if there is no conflict, the various features in the embodiments of the present application can be combined with each other, all within the scope of protection of the present application. In addition, although the functional module division is performed in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a sequence different from the module division in the device or the flow chart. Furthermore, the words "first", "second", "third", etc. used in this application do not limit the data and execution order, but only distinguish the same items or similar items with basically the same functions and effects.

[0043] like Figure 1 As shown, an embodiment of the present application provides a data transmission method, including a plurality of driver chips connected in series at one time, the method comprising:

[0044] Step 110, determining whether the current signal is interrupted.

[0045] In the embodiment of the present application, there are two ways to determine whether the current signal is interrupted. The first way is that when a certain driver chip is detected to be disconnected, it is determined that the current signal is interrupted. The second way is that if the enable signal in front is not received within a preset time, it is determined that the current signal is interrupted. Among them, the preset time can be, for example, 10 seconds, or 20 seconds, etc., which can be set according to actual conditions, without being restricted to the limitations in this embodiment.

[0046] Step 120: If the current signal is interrupted, the data is transmitted in the reverse direction.

[0047] In the embodiments of the present application, Figure 2 As shown, the normal operation of the driver chip is ensured by the tail end backup method. Specifically, when it is detected that the driver chip is disconnected, or the enable signal is not received within a preset time, the data is transmitted forward one by one from the tail end, and the data order of the tail end backup is reversed. It should be noted that in the embodiment of the present application, the driver chip port is an inout type, which can be used as an input port or an output port.

[0048] Step 130: If the current signal is interrupted, the backup signal line is started to transmit data.

[0049] In the embodiments of the present application, Figure 3 As shown, when it is detected that the driving chip is disconnected, or the enable signal is not received within a preset time, the backup signal line is started to bypass the fault point and transmit the data to the next pixel point.

[0050] In an embodiment of the present application, by determining whether the current signal is interrupted, if the current signal is interrupted, the data is transmitted in reverse, or a backup signal line is started for data transmission, thereby preventing a failure of an intermediate driver chip that would cause subsequent driver chips to fail to work properly.

[0051] Accordingly, the embodiment of the present application also provides a data transmission device, such as Figure 4 As shown, the device 400 includes:

[0052] A determination module 410 is used to determine whether the current signal is interrupted;

[0053] The first transmission module 420 is used to transmit data in the reverse direction if the current signal is interrupted; or

[0054] The second transmission module 430 is used to start the backup signal line to perform data transmission if the current signal is interrupted.

[0055] The data transmission device provided in the embodiment of the present application uses a judgment module to determine whether the current signal is interrupted. If the current signal is interrupted, the data is transmitted in reverse through the first transmission module, or the backup signal line is started through the second transmission module for data transmission. This can prevent a failure of a certain driver chip in the middle, which would cause the subsequent driver chips to fail to work properly.

[0056] Optionally, in other embodiments of the device, such as Figure 4 As shown, the determination module 410 is specifically used for:

[0057] When the driver chip is detected to be disconnected, it is determined that the current signal is interrupted; or,

[0058] If the enable signal is not received within the preset time, it is determined that the current signal is interrupted.

[0059] Optionally, in other embodiments of the device, such as Figure 4 As shown, the first transmission module 420 is specifically used for:

[0060] If the current signal is interrupted, the data will be transmitted forward one by one starting from the end;

[0061] Reverse the tail backup data.

[0062] Optionally, in other embodiments of the device, such as Figure 4 As shown, the second transmission module 430 is specifically used for:

[0063] If the current signal is interrupted, the backup signal line is activated to bypass the fault point and transmit the data to the next pixel point.
