[0003] At present, the driving connection methods of LED display screens can generally be divided into two types: array type and daisy chain type.

[0059] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementations. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0060] The core of the present invention is to provide an LED display detection method. A schematic flowchart of one of its specific implementations is as Figure 1 shown, which is called Specific Implementation 1 and includes:

[0061] S101: Send a transfer drive instruction to the target microchip through a data line; the transfer drive instruction causes the target microchip to send a start instruction to the execution microchips on the same daisy chain along the address line; the start instruction causes the execution microchips to send a lighting instruction to the corresponding LED beads.

[0062] In other words, in this step, the transfer drive instruction is sent to microchip A (the target chip). After receiving the transfer drive instruction, microchip A sends the start instruction to microchip B (microchips on the same daisy chain are usually connected in series through the address line). After receiving the start instruction, microchip B sends a lighting instruction to the corresponding LED beads.

[0063] S102: Collect the LED lighting information within the first preset time period after sending the lighting instruction.

[0064] The LED lighting information in this step includes the identity tag of the corresponding LED bead and the information on whether the LED bead emits light normally.

[0065] S103: Determine the LED fault information based on the LED lighting information.

[0066] If the connections between the components in step S101 are all normal, the LED beads will light up normally. If there is a problem in the connection between the components in the previous step, the LED beads will not light up.

[0067] Multiple separate transfer drive instructions can be sent, thereby gradually narrowing the scope of the fault occurrence and gradually locking the fault location. Different transfer drive instructions can also be sent to different target microchips simultaneously in a single time to lock the fault location, and corresponding adjustments can be made according to the actual situation.

[0068] As a preferred embodiment, it further includes:

[0069] A1: Sending an active feedback instruction to the target microchip; the active feedback instruction causes the target microchip to return a reporting feedback instruction through the data line or the address line; the reporting feedback instruction includes the identification information of the corresponding target microchip.

[0070] In this step, the control end sends an active feedback instruction to the target bit chip, that is, the target microchip is commanded to send information to the control end through the data line or the address line (which can be arranged by the tester as appropriate).

[0071] A2: Receiving the reporting feedback instruction.

[0072] Of course, if there is a problem with the connection between the components in step A1, the reporting feedback instruction will not be received. At this time, it can be determined that there is a problem with the link, and the fault can be further located by combining other detection methods in the previous text.

[0073] Correspondingly, the determining the LED fault information according to the LED lighting information includes:

[0074] A3: Determining the LED fault information according to the LED lighting information and the reporting feedback instruction.

[0075] In this specific embodiment, by separately commanding the target microchip to send the reporting feedback instruction to the control end, it is possible to separately detect whether the data line connection or the address line connection between the target microchip and the control end is unobstructed. Combining with other detection means in the previous text, the site where the problem occurs can be quickly located, further improving the detection efficiency.

[0076] This specific embodiment is applicable to an array-type LED panel and also applicable to a daisy-chain LED panel.

[0077] As another preferred embodiment, it further includes:

[0078] B1: Sending a driving instruction to the target microchip; the driving instruction causes the target microchip to send a target lighting instruction to the corresponding LED lamp bead.

[0079] B2: Collecting the target LED lighting information within a first preset time period after sending the target lighting instruction.

[0080] Correspondingly, the determining the LED fault information according to the LED lighting information includes:

[0081] B3: Determining the LED fault information according to the LED lighting information and the target LED lighting information.

[0082] In this specific embodiment, the LED beads corresponding to the power of the target microchip are driven through the control terminal. Generally, the target microchip is all the microchips of the entire LED panel. That is, if the LED panel is fault-free, all the LED beads on the entire panel will be fully lit, and the detection can be completed quickly. If there are LED beads that fail to light up normally, the fault range can be narrowed down to the range of the relevant connecting lines of the unlit LED beads, which can further improve the detection efficiency. This specific embodiment is applicable to array-type LED panels and is also applicable to daisy-chain LED panels.

[0083] The LED display detection method provided by the present invention includes sending a transfer drive instruction to the target microchip through a data line; the transfer drive instruction causes the target microchip to send a start instruction to the execution microchips on the same daisy chain along the address line; the start instruction causes the execution microchips to send a lighting instruction to the corresponding LED beads; collecting the LED lighting information within a first preset time period after sending the lighting instruction; and determining the LED fault information according to the LED lighting information. By utilizing the characteristic that the microchip can actively generate and send signals, the present invention uses the target microchip to issue execution instructions to other microchips (i.e., the execution microchips). The execution microchips that receive the execution instructions then light up the corresponding LEDs. During this process, the connection between the control terminal and the data line of the target microchip, the address line from the target bit chip to the execution microchip, and the connection between the execution microchip and the LED beads can be inspected. One operation can inspect the connections among three structures, which can greatly improve the detection efficiency, speed up the detection, and at the same time, can also improve the detection freedom. Complex target detection can be achieved through simple customization.

[0084] Based on the specific embodiment 1, the detection method is further limited to obtain the specific embodiment 2, and its flow schematic diagram is as Figure 2 shown, including:

[0085] S201: Send a sequential drive instruction to all the microchips on the target daisy chain through the data line; the sequential drive instruction causes the received microchips to send a start instruction to the adjacent execution microchips once along the first direction of the target daisy chain; the one-time start instruction causes the execution microchips to send a lighting instruction to the corresponding LED beads once.

[0086] In this step, instructions are sent to all the microchips on a single daisy chain at the same time. In other words, all the microchips on the target daisy chain are target microchips, and the last microchip in the first direction can send the one-time start instruction to the first microchip.

[0087] S202: Collect the LED one-time lighting information within a first preset time period after sending the one-time lighting instruction.

[0088] S203: Determine the LED fault information according to the LED one-time lighting information.

[0089] In this specific embodiment, the deferral driving instruction is issued to all the microchips on a single daisy chain at one time. The deferral driving instruction is a transit driving instruction that designates the executing microchip as the adjacent microchip in the first direction on the daisy chain. If there is an LED bead that is not lit, it directly indicates that there is a problem with the connection between the LED bead and the corresponding executing microchip, or between the executing microchip and the corresponding target microchip, quickly narrowing down the fault range to the above two points and further improving the detection efficiency. It can be combined with Figure 5 , Figure 5 is the signal sending schematic diagram corresponding to this specific embodiment. Among them, ADDR_EN1, ADDR_EN 2, etc. respectively represent different daisy chains, and ADDR1, ADDR2, etc. respectively represent the addresses of different microchips on a daisy chain. The signal sending schematic diagrams corresponding to other specific embodiments in the following are the same.

[0090] Based on the second specific embodiment, the accuracy of the fault detection result is further refined to obtain the third specific embodiment. Its flow schematic diagram is as Figure 3 shown, including:

[0091] S301: Send a deferral driving instruction to all the microchips on the target daisy chain through the data line; the deferral driving instruction causes the received microchip to send a start instruction once to the adjacent executing microchip along the first direction of the target daisy chain; the one-time start instruction causes the executing microchip to send a lighting instruction once to the corresponding LED bead.

[0092] S302: Collect the LED one-time lighting information within the first preset time period after sending the one-time lighting instruction.

[0093] S303: Send a reverse driving instruction to all the microchips on the target daisy chain through the data line; the reverse driving instruction causes the received microchip to send a secondary start instruction to the adjacent executing microchip along the second direction of the target daisy chain; the secondary start instruction causes the executing microchip to send a secondary lighting instruction to the corresponding LED bead.

[0094] Since the daisy chain is a chain connected by microchips, the second direction is the reverse direction of the first direction.

[0095] S304: Collect the LED secondary lighting information within the first preset time period after sending the secondary lighting instruction.

[0096] S305: Determine LED fault information according to the LED primary lighting information and the LED secondary lighting information.

[0097] In this specific implementation, compared with the second specific implementation, after issuing the first direction forward driving instruction and accepting the first lighting information, the reverse retrograde driving instruction is sent again and the second lighting information is accepted. Combining the two lighting information can further reduce the scope of the fault.

[0098] For example, if it is found through a lighting information that lamp bead ① is not lit, and lamp bead ② is normally lit, it is possible that there is a problem with the connection between lamp bead ① and the corresponding execution microchip B, but it is also possible that there is a problem with the connection between the corresponding execution microchip B and the corresponding target microchip A. At this time, the whole string of reverse driving instructions is sent again. Since lamp bead ② is normally lit in the previous detection, we know that there is no problem with the connection between microchip C corresponding to lamp bead ② and microchip B (relative to microchip C, it is the target microchip). Therefore, if lamp bead ① is normally lit at this time, it means that there is no problem between lamp bead ① and microchip B, and the problem must be at the connection between microchip A and microchip B. In summary, this preferred implementation can further reduce the scope of faults, improve detection efficiency, and thus improve the production efficiency of LED display screens. Figure 6 This is a schematic diagram of signal transmission corresponding to step S303, combined with Figure 5 The complete signal sending process in this specific implementation manner can be obtained.
