Embodiment 1

[0047] In this embodiment, M=1, that is, between the first circuit board 301 and the second circuit board 302 such as image 3 As shown, only one level of connection assembly 30 is provided.

[0048] In this case, the first pin ① of the first connector 301 is connected to the voltage source VDDIN for receiving the signal provided by the voltage source VDDIN. The signal provided by the voltage source VDDIN can be directly used as the above-mentioned test signal T.

[0049] The i-th pin of the first connector 301 is connected to the enable signal end EN for outputting the signal on the i-th pin of the second connector to the enable signal end EN.

[0050] In this way, if the signal provided by the above-mentioned voltage source VDDIN can be transmitted to the first pin ① of the second connector 302 through the first pin ① of the first connector 301 . In this case, since the first pin ① of the second connector 302 is connected to the i-th pin of the second connector 302, the si...

Embodiment 2

[0056] In this embodiment, M>1, that is, between the first circuit board 301 and the second circuit board 302 such as Figure 4 As shown, a multi-stage connection assembly 30 is provided. in image 3 From top to bottom, there are first-level connection components 30 , second-level connection components 30 . . . and last-level connection components 30 .

[0057] In this case, the first pin of the first connector 301 in the first-level connection component 30 is connected to the voltage source VDDIN for receiving a signal provided by the voltage source VDDIN.

[0058] In addition to the first-level connection assembly 30, the first pin of the first connector 301 in the remaining connection assemblies 30 is connected to the i-th pin of the first connector 301 in the upper-level connection assembly for realizing adjacent connections cascading between components 30 .

[0059] The i-th pin of the first connector 301 in the last-level connection assembly 30 is connected to the ena...

Abstract

Embodiments of the present invention provide a driving component and a display device, which relate to the field of display technology and can solve the problem of damage to a PCBA due to misalignment between an FFC and a connector. The drive unit includes a first circuit board, a second circuit board, and M-level connection assemblies, each connection assembly includes a first connector disposed on the first circuit board, a second connector disposed on the second circuit board, and a connecting wire . One end of the connecting wire is provided with N pins corresponding to the N pins of the first connector, and the other end of the connecting wire is provided with N pins respectively corresponding to the N pins of the second connector. One correspondence; the first pin of the first connector is used to receive the test signal, the first pin of the second connector is electrically connected to the i-th pin of the second connector; the second circuit board is provided with The first pull-down module is connected to the jth pin of the second connector and the ground terminal, and is used for pulling down the signal of the jth pin of the second connector to the ground terminal.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving component and a display device. Background technique [0002] FFC (English: Flexible Flat Cable, Chinese: Flexible Flat Cable) has excellent performances such as small size, high precision, convenient use, portability, ultra-thin shape, and resistance to twists and turns. During the preparation process of electronic products, two PCBAs (English: Printed Circuit Board Assembly, Chinese: Printed Circuit Board) can be electrically connected. [0003] In the prior art, a connector is provided on the PCBA, and the electrical connection of the two PCBAs can be realized by respectively inserting the two ends of the FFC into the sockets of the connectors on the two PCBAs. [0004] However, in the actual production process, when the FFC is inserted into the connector, the connection position may be misplaced. In this way, it is easy to cause a short circuit in the circuit, re...
