Abstract
The utility model provides a FPC on the ON CELL touch -sensitive screen, includes the FPC body, the FPC body the upper surface for with the mutual absorbent adsorption plane of pressure head, the lower surface face of binding for binding with CTP, be provided with the double faced adhesive tape on the adsorption plane, the one end of FPC body is free end, its characterized in that for CTP laminating end, the other end: the double faced adhesive tape be more than or equal to pressure head along the thickness of FPC body to the outside extending direction of CTP to the distance between the CTP laminating end. Adopt above -mentioned structure, owing to be more than or equal to pressure head along the thickness of FPC body to the outside extending direction of CTP with the double faced adhesive tape to the distance between the CTP laminating end, adsorb FPC at the pressure head so and just can levelly and smoothly laminate with FPC's upper surface completely time, improvement area of contact, the reduction risk of leaking gas to prevent effectively that FPC from throwing the appearance of material phenomenon, effectively guarantees work efficiency's stability.
Description
Technical field
The utility model relates to flexible circuit board (FPC) technical field that mobile phone uses, and is specifically related to FPC on a kind of ONCELL touch-screen.
Background technology
Flexible circuit board (FPC), also known as " soft board ", is the printed circuit made with flexible insulating substrate; Because it is soft, light and reliability is high, there is good flexibility, free bend, volume scratched, folding, the dynamic bending of millions of times can be born and do not damage, therefore, being applied in mobile phone, apparatus such as computer by a large amount of.
ONCELL refers to the method be embedded into by touch panel function between colored filter substrate and Polarizer.Original technology is that liquid crystal display screen is together with touch panel component combination; FPC is pasted on touch-screen by the mode of hot pressing.As shown in Figure 1, FPC1 ' is pasted onto touch-screen 2 ' by the mode of hot pressing; Shaping be generally first touch-screen to be placed on vacuum absorbing platform 6 ' fix position, then touch-screen need adhere to FPC position on hot pressing one deck ACF3 ' i.e. anisotropic conductive film; Then pressure head is by the method for vacuum suction, and an end face of an end face and FPC brings it to above touch-screen, depresses downward vertically; FPC, before binding with touch-screen, the one side of its pressure head absorption will stick double faced adhesive tape 4 ' in advance, and this double faced adhesive tape needs turnover past and backboard after FPC posts to paste; But its distance to FPC end of double faced adhesive tape more at present is generally all less than the pressure head width of absorption FPC, so just cause pressure head absorption FPC process in make with FPC surface contact injustice (part for FPC surface, a part is double faced adhesive tape surface), cause vacuum leak, be easy to occur not adsorbing in moving process, the risk that FPC comes off, causes FPC material casting, has a strong impact on laminating efficiency.
Utility model content
The utility model, for the above-mentioned deficiency of prior art, provides one not easily to cause FPC material casting, adsorbs firmly FPC on ONCELL touch-screen.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: FPC on a kind of ONCELL touch-screen,. comprise FPC body, the upper surface of described FPC body is the adsorption plane, the lower surface that mutually adsorb with pressure head is the binding face of binding with CTP, and adsorption plane is provided with double faced adhesive tape; One end of FPC body is CTP laminating end, the other end is free end, it is characterized in that: the distance between described double faced adhesive tape to CTP laminating end is more than or equal to the thickness of pressure head outside bearing of trend along FPC body to CTP.
Adopt said structure, owing to the distance between double faced adhesive tape to CTP laminating end to be more than or equal to the thickness of pressure head outside bearing of trend along FPC body to CTP; So just completely and the smooth laminating of the upper surface of FPC, contact area can be improved, reduces risk of leaking gas, thus effectively prevent the appearance of FPC material casting phenomenon when pressure head absorption FPC, the stability of effective guarantee operating efficiency.
As preferably, the distance between described double faced adhesive tape to CTP laminating end equals the thickness of pressure head outside bearing of trend along FPC body to CTP; Pressure head and FPC more accurately locate to adopt this structure to ensure, the CTP of the end of pressure head and FPC is fitted and holds easier precise calibration contraposition.
As preferably, the distance between described double faced adhesive tape to CTP laminating end is 2mm; This structure guarantee FPC is adopted to turn down when fitting cover plate more firm, reliable.
Accompanying drawing explanation
The structural representation of the binding flexible circuit board of Fig. 1 prior art.
The structural representation of Fig. 2 the utility model binding flexible circuit board.
The structural representation of Fig. 3 the utility model flexible circuit board.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail, but is not limited only to following examples.
Embodiment.
As illustrated in figs. 2-3: FPC on a kind of ONCELL touch-screen of the present utility model,. comprise FPC body 1, the upper surface of described FPC body 1 is the adsorption plane 1.1, the lower surface that mutually adsorb with pressure head 5 is the binding face 1.2 of binding with CTP, adsorption plane is provided with double faced adhesive tape 4; One end of FPC body is CTP laminating end 1.3 (lower surface and the CTP of this end close fit), the other end is free end 1.4, it is characterized in that: the distance between described double faced adhesive tape 4 to CTP laminating end is more than or equal to the thickness of pressure head 5 outside bearing of trend along FPC body to CTP.
Adopt said structure, owing to the distance between double faced adhesive tape to CTP laminating end to be more than or equal to the thickness of pressure head outside bearing of trend along FPC body to CTP; So just completely and the smooth laminating of the upper surface of FPC, contact area can be improved, reduces risk of leaking gas, thus effectively prevent the appearance of FPC material casting phenomenon when pressure head absorption FPC, the stability of effective guarantee operating efficiency.
Distance between double faced adhesive tape described in this practicality to CTP laminating end equals the thickness of pressure head outside bearing of trend along FPC body to CTP; Pressure head and FPC more accurately locate to adopt this structure to ensure, the CTP of the end of pressure head and FPC is fitted and holds easier precise calibration contraposition.
Distance between double faced adhesive tape described in this practicality to CTP laminating end is 2mm; This structure guarantee FPC is adopted to turn down when fitting cover plate more firm, reliable.
As shown in Figure 2: the CTP touch-screen 2 of this practicality is placed in absorption location on vacuum absorbing platform 6, CTP touch screen upper surface arranges ACF3, and top is pressure head 5, and pressure head 5 bottom surface is for adsorbing the FPC body 1 with double faced adhesive tape 4, downward pressing, realizes CTP touch-screen and FPC binding.
