Because the upper surface adopts heavy release film 1, the lower surface adopts light release film 8, heavy release film 1 needs is great from the type power, light release film 8 needs from the type power lower, can tear light release film 8 earlier when tearing off from the type film, avoid tearing light release film 8 when tearing off from the type film of opposite side and tear off, and because the inboard of heavy release film 1 is provided with first transparent acrylic acid layer 2, make it need not to attach OCA optical cement and UV solidification after tearing off heavy release film 1 can directly laminate with the apron, production manufacturing process has been simplified, make liquid crystal display module's production and manufacturing cost reduce. The blue light preventing coating 3 coated on the first TAC layer 4 can filter blue light generated by the liquid crystal display module, so as to avoid damage of the blue light to eyes of a user. In addition, the second transparent acrylic acid layer is a conductive transparent acrylic acid layer, so that the second transparent acrylic acid layer can be matched with conductive silver paste for use, static electricity on the surface of a display main screen can be dispersed, static electricity aggregation generated after film tearing is avoided, abnormal display of a liquid crystal display module is avoided, and the probability of defective products of the liquid crystal display module is reduced. The fool-proof characters arranged on the heavy release film 1 and/or the light release film 8 can avoid the reverse pasting of the heavy release film and/or the light release film when the release film is pasted, thereby improving the product competitiveness of the multifunctional polaroid and meeting the increasing quality requirements of enterprises.
Further, foolproof characters "F" are arranged on the heavy release film 1, foolproof characters "B" are arranged on the light release film 8, or foolproof characters "F" are arranged on the heavy release film 1 and foolproof characters "B" are arranged on the light release film 8, so that staff can attach the heavy release film 1 and the light release film 8 in a direction distinguishing manner.
Further, the first transparent acrylic acid layer 2 is a conductive transparent acrylic acid layer or a non-conductive transparent acrylic acid layer, when the conductive transparent acrylic acid layer is selected, static electricity of the cover plate can be led out, and the antistatic capacity is improved.
Example 2

Example 3
Referring to fig. 2 and 3, in this embodiment, a concave-shaped through hole 11 is formed in the heavy release film 1, and the concave-shaped through hole 11 forms a film tearing handle 12 as a further optimization scheme of embodiment 1. Therefore, the film tearing handle 12 is not required to be additionally arranged on the periphery of the heavy release film 1, so that the film tearing handle 12 cannot be placed due to the limitation of peripheral space, the condition that tweezers are required to be used for warping during the limitation of the peripheral space is avoided, and further the labor cost is saved; and the material of the peripheral dyestripping handle 12 can be omitted, so that the material cost can be greatly reduced.
Referring to fig. 4, further, the waste 13 of the "concave" shaped through hole 11 remains on the heavy release film 1. Before tearing off the heavy release film 1, the waste 13 is still connected with the heavy release film 1, so that dust or other particles can be effectively prevented from entering the surface of the product. Since the waste 13 is further connected to the heavy release film 1, it is difficult to tear the film tearing handle 12, and therefore, an adhesive area 14, preferably an adhesive, can be disposed on the upper surface of the waste 13, but not limited thereto, when the heavy release film 1 is torn off, the waste 13 can be torn off by the adhesive first, and then the heavy release film 1 is torn off by the film tearing handle 12.
Further, the concave through hole 11 is arranged at the edge of the heavy release film 1, so that the heavy release film 1 is easy to tear when being torn, and the tearing of the film handle 12 due to higher tearing difficulty is avoided.
Further, each corner of the concave through hole 11 is provided with a rounded corner, so that stress during film tearing is not concentrated at the corner, the film tearing handle 12 is prevented from being torn due to stress concentration, and the operation efficiency is further improved.
Further, the radius of the rounded corner is 1mm.
In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
