Description

Technical Field

[0001] The utility model belongs to the technical field of display modules, and particularly relates to a three-section FPC transfer test line. Background Art

[0002] At present, in the display screen industry, when performing functional tests on liquid crystal display screens, the traditional FPC structure for connecting display screens is an integrated structure. When detecting the screen, it is necessary to frequently plug and unplug the display screen and the FPC, which easily causes problems such as damage to the screen connector during multiple plugging and unplugging processes. Once the screen connector is damaged, the repair cost is high, resulting in great losses for production.

[0003] Based on this, in order to reduce the number of plugging and unplugging times between the FPC and the screen during the test process, this design proposes a three-section FPC transfer test line. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a three-section FPC transfer test line.

Among them, the right end of the product-end FPC is connected to the display screen, the lower left part of the product-end FPC is connected to the upper part of the circuit board, the upper part of the test box FPC is connected to the lower part of the circuit board, and the lower part of the test box FPC is connected to the test box.

[0006] Preferably, the product-end FPC includes a product connection end and a circuit board connection end A. The product connection end is connected to the connection board of the display screen through pins, and the circuit board connection end A is connected to the upper part of the circuit board through pins.

[0007] Preferably, the circuit board includes: a product-end FPC connection part and a test box FPC connection part. The product-end FPC connection part is arranged on the upper part of the circuit board and is connected to the circuit board connection end A, and the test box FPC connection part is arranged on the lower part of the circuit board and is connected to the circuit board connection end B.

[0008] Preferably, the test box FPC includes: a circuit board connection end B and a test box connection end. The circuit board connection end B is connected to the test box FPC connection part at the lower part of the circuit board, and the test box connection end is connected to the test box.

[0009] The beneficial effects of the above solution are:

[0010] 1. The utility model divides the FPC into a product - end FPC and a test - box FPC, and the middle part is connected through a circuit board. During testing, the FPC can be separated. The product - end FPC can always be connected to the display screen, so that faults caused by frequent plugging and unplugging between the product - end FPC and the display - connecting board can be avoided, thus preventing losses to the product. The test - box FPC can be tested separately, and the product - end FPC is processed separately with the product display screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following further clearly and completely describes the utility model with reference to the attached drawings of the specification, but the protection scope of the utility model is not limited thereto.

[0016] According to Figure 1 , Figure 2 , Figure 3 shown, a three - section FPC adapter test line includes: a product - end FPC 1, a circuit board 2, and a test - box FPC 3. Among them, the right end of the product - end FPC 1 is connected to the display screen, the lower left part of the product - end FPC 1 is connected to the upper part of the circuit board 2, the upper part of the test - box FPC 3 is connected to the lower part of the circuit board 2, and the lower part of the test - box FPC 3 is connected to the test box.

[0017] Specifically, the product - end FPC 1 includes a product connection end 11 and a circuit - board connection end A 12. The product connection end 11 is connected to the connection board of the display screen through pins, and the circuit - board connection end A 12 is connected to the upper part of the circuit board 2 through pins.

[0018] Specifically, the circuit board 2 includes: a product - end FPC connection part 21 and a test - box FPC connection part 22. The product - end FPC connection part 21 is arranged on the upper part of the circuit board 2 and is connected to the circuit - board connection end A 12, and the test - box FPC connection part 22 is arranged on the lower part of the circuit board 2 and is connected to the circuit - board connection end B 31.

[0019] Specifically, the test box FPC3 includes a circuit board connection end B31 and a test box connection end 32. The circuit board connection end B31 is connected to the test box FPC connection part 22 at the lower part of the circuit board 2, and the test box connection end 32 is connected to the test box.

[0020] During the test work, the product end FPC1 moves with the test product. While detecting the product, the FPC connected to the product connection board can also be detected simultaneously. After the detection is completed, the product end FPC1 is then connected to the product end FPC connection part 21 of the circuit board 2, and then waits for detection. While the product end FPC is being detected, the test box FPC3 can be independently detected by the test box. After the detection is completed and found to be error-free, the test box FPC is connected to the circuit board 2, and then the entire detection process is completed. Throughout the process, the product end FPC is always connected to the product connection board. Compared with the traditional detection of a whole piece of FPC, the number of insertions and extractions between the FPC and the product connection board can be reduced, ensuring a tight connection between the FPC and the product connection board and reducing product losses.
