Description
Technical field
This utility model relates to Display Technique field, particularly relates to a kind of chip on film with auxiliary detaching structure and shows
Showing device.
Background technology
The scheme of present COF (Chip On Flex, or, Chip On Film often claim chip on film) gets more and more, as
The driving chip of touch screen is the most all welded on FPC (Flexible Printed Circuit board, the flexible print of touch screen
Printed circuit board, also referred to as flexible circuit board) on, in general, COF welding portion is required for viscose glue and fixes, and is much requirement
It is pasted onto on mainboard.But COF is after pasting on mainboard, all there is some problems when dismounting, as follows to the shortcoming of different schemes:
1) existing design one: directly use double faced adhesive tape to be fixed on mainboard the chip position of COF, need during maintenance
Lever up with tweezers, plectrum, or the non-adhesive portion of direct pull COF is dismantled.The method has open defect: a, easily damages
Mainboard；B, the FPC of very easy damage COF；C, dismounting difficulty；
2) existing design two: need the adhesive portion edge of COF on mainboard to do a through hole on mainboard, dismounting
Shi Caiyong tweezers lever up at the edge in hole, it is achieved dismounting.The shortcoming of this scheme: a, affect the layout of mainboard.Owing to needs are being led
Do through hole in the middle of plate, the cabling of mainboard can be had a strong impact on.B, can not stop completely to damage mainboard and COF.
Utility model content
The deficiency existed in view of prior art, this utility model provides a kind of COF with auxiliary detaching structure and shows

Repair demolition and with low cost.
In order to realize above-mentioned purpose, this utility model have employed following technical scheme:
A kind of chip on film with auxiliary detaching structure, including flexible circuit board, is positioned in described flexible circuit board
Chip and with the dorsal edge of described flexible circuit board relatively-stationary auxiliary dismounting bar, described auxiliary dismounting bar part stretch out
In described flexible circuit board.
As one of which embodiment, the described chip on film with auxiliary detaching structure also includes stiffening plate, institute
The inner surface stating stiffening plate fits in the back side of described flexible circuit board.
As one of which embodiment, the dismounting bar laminating of described auxiliary is fixed on the outer surface of described stiffening plate.
As one of which embodiment, the described chip on film with auxiliary detaching structure also includes being pasted onto described
The double faced adhesive tape of the outer surface of stiffening plate.
As one of which embodiment, the described chip on film with auxiliary detaching structure also includes one layer of protection
Layer, described protective layer is pasted onto the outer surface of described chip.
As one of which embodiment, described protective layer is connected with described auxiliary dismounting bar, and oneself of described protective layer
Described chip is stretched out in by end.
As one of which embodiment, described protective layer is integrally formed with described auxiliary dismounting bar, is high-temp glue.
Another object of the present utility model is to provide a kind of display device, thin including mainboard and any of the above flip
Film, described chip on film is pasted onto on described mainboard.
Chip on film of the present utility model has the auxiliary dismounting bar of auxiliary dismounting, from mainboard during dismounting chip on film only
Need to uncover this auxiliary dismounting bar and can separate chip on film, very convenient, can avoid damaging pcb board and FPC, and low cost
Honest and clean.
Accompanying drawing explanation
Fig. 1 is the structural representation that the COF of this utility model embodiment coordinates with mainboard.
Fig. 2 is the partial enlarged drawing in Fig. 1 at A.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, further describes this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this reality
With novel, it is not used to limit this utility model.
Refering to Fig. 1, display device of the present utility model includes mainboard 10 and chip on film 20, and chip on film 20 is by two-sided
Glue S is pasted onto on mainboard 10 (i.e. pcb board).
The chip on film with auxiliary detaching structure of the present embodiment includes flexible circuit board 1, is positioned in flexible circuit board 1
Chip 2 and other element etc. and the relatively-stationary auxiliary dismounting bar 3 with the dorsal edge of flexible circuit board 1, auxiliary dismounting
Bar 3 part stretches out in flexible circuit board 1.
When needs separate mainboard 10 with when being easy to chip on film 20, it is only necessary to tear auxiliary dismounting bar 3, flexible circuit board
1 can be torn from mainboard 10 the most together, simple to operate, will not damage mainboard and flexible circuit board.
Shown in Fig. 2, chip on film 20 also includes that stiffening plate 4, the inner surface of stiffening plate 4 fit in flexible circuit board 1
The back side, auxiliary dismounting bar 3 laminating is fixed on the outer surface of stiffening plate 4, and stiffening plate 4 one aspect can improve flexible circuit board 1
Planarization and overall easy-to-rupture, on the other hand can improve the structural strength of flexible circuit board 1.Double faced adhesive tape S is pasted onto stiffening plate 4
Outer surface.By this double faced adhesive tape S, chip on film 20 can be pasted onto on mainboard 10 securely.The preferably thickness of double faced adhesive tape S is big
In auxiliary dismounting bar 3 so that after chip on film 20 pastes on mainboard 10, between auxiliary dismounting bar 3 and mainboard 10, still suffer from one
Fixed gap, the end of flexible circuit board 1 is more easy to tilt under the drive of auxiliary dismounting bar 3, and easy-to-rupture is more preferable.
Further, protective layer 5 is pasted onto the outer surface of chip 2, preferably protective layer 5 and is connected with auxiliary dismounting bar 3, and protects
The free end of sheath 5 stretches out in chip 2, in order to tear up as tearing end.Preferably embodiment is, protective layer 5 and auxiliary
Dismounting bar 3 is integrally formed, and both at high-temp glue, draws materials simple and with low cost, and feasibility is high.
Chip on film of the present utility model has the auxiliary dismounting bar of auxiliary dismounting, from mainboard during dismounting chip on film only
Need to uncover this auxiliary dismounting bar and can separate chip on film, very convenient, can avoid damaging pcb board and FPC, and low cost
Honest and clean.
The above is only the detailed description of the invention of the application, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the application principle, it is also possible to make some improvements and modifications, these improvements and modifications also should
