Description

Technical Field

[0001] The utility model relates to the technical field of display modules, and in particular to a module FPC and a display module. Background Art

[0002] At present, the module FPC in the LCD module industry is usually designed with double-sided conductive adhesive. One side of the conductive adhesive is affixed to the exposed copper on the module FPC, and the other side is used to stick to the backlight iron frame after the module FPC is bent, so that the exposed copper area on the FPC is firmly in contact with the backlight iron frame, that is, the module FPC and the backlight share a common ground, so that static electricity can be quickly released when static electricity occurs. The exposed copper design on the module FPC is generally divided into several blocks to avoid wiring, but the conductive adhesive is designed to be a whole piece that completely covers all exposed copper. This structure makes the conductive adhesive area large and the cost high, and once the module FPC is affixed to the backlight iron frame, it is easy to pull the module FPC when you want to rework it later and tear it off, causing damage to the module FPC.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to overcome at least part of the deficiencies of the prior art and provide a module FPC and a display module.

[0006] Furthermore, the conductive adhesive body layer covers the entire area of ​​the copper exposed area.

[0007] Furthermore, the number of the copper exposed areas is 2.

[0008] Furthermore, a tear handle portion is formed on the release film layer.

[0009] The utility model also provides a display module, comprising the above-mentioned module FPC.

[0010] Furthermore, the display module further comprises a liquid crystal module and a backlight module, the module FPC is bound and connected to a single-layer area of ​​the liquid crystal module, and the liquid crystal module and the backlight module are stacked.

[0011] By adopting the above scheme, the beneficial effects of the utility model are: the usage of the conductive adhesive body layer can be reduced, which can save material costs; it can avoid the conductive adhesive body layer pulling the module FPC during rework to cause damage to the module FPC, which can improve the rework efficiency and yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0013] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Please refer to Figure 1 In this embodiment, the utility model provides a module FPC, including: a module FPC body 1 and a conductive adhesive attached to the module FPC body 1, two copper-exposed areas 11 are formed on the module FPC body 1, the conductive adhesive includes a conductive adhesive body layer 21 and a release film layer 22, the conductive adhesive body layer 21 and the release film layer 22 are stacked, the conductive adhesive is attached to the copper-exposed area 11 through the conductive adhesive body layer 21, and the conductive adhesive body layer 21 is only attached to the copper-exposed area 11. Under the structural setting of this scheme, the conductive adhesive body layer 2 is not attached to the non-copper-exposed area of ​​the module FPC body 1, so the use area of ​​the conductive adhesive body layer 21 can be reduced, thereby reducing the use of materials, and also avoiding the need to rework and tear off the conductive adhesive body layer 21 after the module FPC is attached to the back of the backlight module, and the conductive adhesive body layer 21 will pull the non-copper-exposed area of ​​the module FPC body to cause the module FPC to be defective.

[0015] Furthermore, in this embodiment, the conductive adhesive body layer 21 covers the entire area of ​​the copper exposed area 11, that is, the conductive adhesive body layer 11 and the copper exposed area layer 21 are completely overlapped. This structure can maximize the area of ​​the conductive adhesive body layer 21 and ensure good adhesion and conductive effects.

[0016] Furthermore, a tearing hand portion 221 is formed on the release film layer 22, which can be convenient for separating the release film layer 22, and then bending and attaching the module FPC after tearing the film. Moreover, since the two unconnected areas of the conductive adhesive body layer 21 are attached to the same release film layer 22, it is also convenient for initially attaching the conductive adhesive to the module FPC body 1, and when the release film layer 22 is subsequently torn off, the release film layer 22 on the corresponding conductive adhesive layer 21 on the two copper exposed areas 11 can be torn off at one time.

[0017] The utility model also provides a display module, comprising the above-mentioned module FPC.

[0018] Furthermore, the display module further comprises a liquid crystal module and a backlight module, the module FPC is bound and connected to a single-layer area of ​​the liquid crystal module, and the liquid crystal module and the backlight module are stacked.

[0019] In summary, the beneficial effects of this solution are: it can reduce the usage of the conductive adhesive body layer, saving material costs; it can avoid the conductive adhesive body layer pulling the module FPC during rework to cause damage to the module FPC, and can improve rework efficiency and yield.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
