Description
Technical field
The present invention relates to a kind of plasticizing diaphragms and preparation method thereof.In particular to a kind of optical diaphragm group and its production side
Method.
Background technique
Has the plasticizing diaphragm of high-insulativity, because having the property of accumulation electrostatic, in the object that will not leak electrostatic with other
Electrostatic can be generated when friction or removing, not only the dirt in air, dust etc. are easy to attach, but will make two two films being in contact with each other
Piece mutually sticks together.
When the packaging technology of liquid crystal display panel to be carried out, single piece of optical diaphragm is generally drawn with vacuum slot, to carry out
Back segment assembling or working process.Due to, there are electrostatic, causing mutually to inhale between optical diaphragm between the optical diaphragm of mutual storehouse
Draw glutinous piece, can not once pluck single piece of optical diaphragm, and interrupt packaging technology, influences the production capacity and yield of liquid crystal display panel.
Summary of the invention
The purpose of the present invention is to provide a kind of advanced optical diaphragm group and glutinous piece method is prevented, to solve the prior art
Problem encountered.
It is to provide a kind of optical diaphragm group, including the first optical diaphragm and the second light according to an embodiment of this specification
Learn diaphragm, the first optical diaphragm and the second optical diaphragm respectively include first surface and the opposite side positioned at first surface
Second surface.Wherein, first surface has the first roughness, and second surface has the second roughness；First optical diaphragm and
When two optical diaphragms are mutually superimposed, between the first surface of the first optical diaphragm and the second surface of the second optical diaphragm most with one
Big pulling force.And first the numerical value of roughness and the second roughness be always essentially less than 1000 with the numerical value product of maximum pull.
It is to provide a kind of method for preventing optical diaphragm from sticking piece, including following steps according to another embodiment of this specification
Rapid: firstly, providing at least two optical diaphragms, making each optical diaphragm includes first surface and the phase positioned at first surface
The second surface of anti-side；And makes first surface that there is the first roughness, make second surface that there is the second roughness.Then heap
These optical diaphragms of stack, contact the first surface of one of optical diaphragm with the second surface of another one.Wherein, first is coarse
The numerical value product of degree and the total maximum pull between first surface and second surface of numerical value of the second roughness is essentially less than 1000.
According to above-mentioned, a kind of method that the embodiment of this specification proposes optical diaphragm group and prevents its glutinous piece, by making
The surface that optical diaphragm is located at two opposite sides has different roughness, and meets two surface roughness values sum total and the two
Between maximum pull condition of the numerical value product less than 1000.Come at least two optical diaphragms when reducing mutual storehouse due to electrostatic
The chance of glutinous piece occurs, to solve the problems, such as that the prior art causes packaging technology production capacity and yield bad because optical diaphragm sticks piece.
Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail, but not as a limitation of the invention.

Specific embodiment
This specification is to provide a kind of optical diaphragm that glutinous piece problem will not occur in packaging technology and prevents its glutinous piece
Method, can effectively promote liquid crystal display panel assembling technique production capacity and yield.To allow above and other purpose of the invention, feature
It can be clearer and more comprehensible with advantage, connection with several embodiments detailed description is cited below particularly.
But it must be noted that these specific case study on implementation and method, be not intended to limit the invention.The present invention still may be used
It is implemented using other features, component, method and parameter.The it is proposed of preferred embodiment is only of the invention to illustrate
Technical characteristic, the scope of the claims being not intended to limit the invention.Have usually intellectual in the technical field, it can basis
The description of following description is not departing from scope of the invention, makees impartial modification and variation.
Figure 1A and Figure 1B are please referred to, Figure 1A is a kind of optical diaphragm 100 according to depicted in an embodiment of this specification
