Description
Background technology
The present invention relates to employed liquid crystal utensil in the injection equipment.This liquid crystal utensil is used for storing the injection liquid crystal in advance when liquid crystal panel injects liquid crystal.
In existing injection equipment in the employed liquid crystal utensil, disclosed for example have that the spy opens the disclosed liquid crystal utensil of flat 9-54327 communique (patent documentation 1).
For example, as shown in Figure 1, liquid crystal utensil 110 can be as the container that stores liquid crystal 20 in injection equipment.Liquid crystal utensil is to be made of the lyophoby crystallinity material in the patent documentation 1.Usually, in liquid crystal utensil 110 general use known be the material of friction factor minimum teflon (polytetrafluoroethylene, PTFE).PTFE is commonly called Teflon (Teflon, registered trademark).Bring into play the capillary character of the liquid crystal 20 that raising that this lyophoby crystallinity material had and hydrophobicity contact with lyophoby crystallinity material, liquid crystal utensil 110 is deposited in liquid crystal 20 upper surface of liquid crystal utensil 110.The liquid crystal 20 of this accumulation is injected into and is filled into inside from the inlet 33 of panel 31.
Herein, simultaneously referring to figs. 1 through Fig. 5, this method for implanting is described.
On liquid crystal utensil 110, liquid crystal 20 is piled up from upper surface.
It is in proper order: at first, in the chamber 30 that is in vacuum state, use elevating mechanism 32 that the liquid crystal utensil 110 with liquid crystal 20 is risen to panel 31 directions.And as shown in Figures 2 and 3, elevating mechanism 32 makes liquid crystal utensil 110 contact with panel 31.By this contact, utilize capillarity, a spot of liquid crystal 20 is introduced into the inside of panel 31 from inlet 33, and liquid crystal 20 stops up inlets 33.Then the air pressure in the chamber 30 is returned to atmospheric pressure.In the variation of this air pressure, liquid crystal 20 utilizes pressure differential and capillarity effect to be attracted to the inside of panel 31 gradually.Consequently, liquid crystal 20 has been full of the inside of panel 31.
Existing liquid crystal utensil 110 stores in being included in liquid crystal utensil 110 on all surfaces of groove of liquid crystal 20 all has the lyophoby crystallinity.Therefore, the liquid crystal utensil 110 of lyophoby crystallinity material demonstrates the powerful hydrophobicity that the liquid crystal that is filled in this groove is piled up from upper surface.On the other hand, the liquid crystal on the liquid crystal utensil 110 must carry out with sneak into the deaeration operation that gas inside is sloughed before panel 31 contacts.By this deaeration operation, the gas that is included in the liquid crystal 20 is discharged in the space outerpace of liquid crystal 20.
But, because the viscosity height of liquid crystal 20, thereby when by this degassing process gas being discharged to space outerpace, gas is grown up easily and is formed bubble.And then, owing to this bubble is difficult to break, thereby can grow into bigger bubble with other bubble incorporation.In the deaeration operation, need bubble be broken so that make the operation that does not have gas in the liquid crystal 20, carry out deaeration.But,, as shown in Figure 4, produce the space 21 that does not have liquid crystal 20 at this position in the moment of lather collapse.Particularly, because the inner face of groove all has hydrophobicity, thereby the liquid crystal 20 in the groove just can be kept the space 21 that has produced by surface tension own.The phenomenon that produces such space 21 is called as the liquid fracture.Because the groove inner face of liquid crystal utensil 110 has hydrophobicity, thereby liquid crystal 20 is difficult to expansion, even also can the residual liquid breaking state after the deaeration operation finishes.
Under this state, as shown in Figure 5, when panel 31 contacted with liquid crystal utensil 110, just becoming can not be to supplying the fully state of affairs of the liquid crystal 20 of necessity with the space 21A of liquid breaking state, panel 31A, the 31B that 21B contacts.In addition, owing to inlet is not stopped up by liquid crystal 20, thereby when returning to atmospheric pressure in the chamber 30, gas is sneaked in the panel, causes injecting defective mode.
In the prior art, for fear of this liquid breaking state, normally the liquid fracture location after deaeration appends filling liquid crystal, perhaps is pre-charged with the above liquid crystal of necessary amounts.Such solution has increased flow chart, and, owing to fill superfluous liquid crystal, thereby the utilization ratio of liquid crystal reduces.Consequently cause cost to increase.
As one of its innovative approach, open for example spy and to disclose the service efficiency that can improve expensive liquid crystal material in the 2002-244142 communique (patent documentation 2), and can supply with the liquid crystal utensil of liquid crystal material accurately.This liquid crystal utensil has on the dip plane by tilting to inject the injection groove of an amount of liquid crystal.This injection groove uses has good infiltrating material formation bottom surface to liquid crystal material, and uses hydrophobic coating to form other wall.Therefore, when when an end injects liquid crystal,, thereby can inject an amount of liquid crystal of groove injection with good flowability because the bottom surface is for having good infiltrating material.
But, in this structure, structure and control all more complicated, thereby be necessary to simplify.
Problem of the present invention is to solve the problem that can not improve the utilization ratio of expensive liquid crystal material owing to can not avoid the liquid breaking state in the deaeration operation.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of liquid crystal utensil, it can avoid the liquid breaking state in the deaeration operation, and can improve the utilization ratio of expensive liquid crystal material.
The present invention relates to be used for display panels inject liquid crystal injection equipment and the surface have hydrophobic liquid crystal utensil.
In the present invention, for fear of the liquid breaking state in the deaeration operation, on the inner face of the slot part of the storage liquid crystal that liquid crystal utensil had, implement to reduce hydrophobic processing to improve water wettability.And be primarily characterized in that: reduce hydrophobic processing and implement in side that forms the slot part inner face and bottom surface, the liquid crystal utensil upper surface all keeps hydrophobicity.
That is because that the slot part inner face becomes is hydrophilic, thereby liquid crystal this reduce and can observe expansion in slot part inner face upper surface tension force.Therefore, the space that is produced in the time of can breaking by the bubble that the expansion of the liquid crystal on the slot part inner face is eliminated in liquid crystal to be produced.
The hydrophobic processing of above-mentioned reduction comprises for example Corona discharge Treatment, the slot part surface treatments such as processing, milled processed of sandblasting.In addition, also comprise processing such as generation is concavo-convex, linearity muscle, toroidal muscle.

Embodiment
The objective of the invention is in the liquid crystal utensil that hydrophobic material constitutes, avoid generation at the bubble of the liquid crystal inside that has been stored.In order to realize this purpose, in the slot part of the liquid crystal utensil that stores liquid crystal, on as the side of its inner face and bottom surface, implement to reduce hydrophobic processing.Consequently, do not damage the succinct structure of existing injection equipment.
Hydrophobic material is meant the material that friction factor is little, and the material of the friction factor minimum of being found up to now comprises Teflon (registered trademark).Teflon (registered trademark) is the trade name of fluororesin polytetrafluoroethylene (PTFE), at present, is commonly referred to as fluororesin.Therefore, can certainly use other fluororesin.In addition,, also can use the material except fluororesin, for example polypropylene etc. although what are poorer for hydrophobicity.
Below, with reference to accompanying drawing embodiment is described.In order to understand easily invention, show accompanying drawing in a kind of mode of exaggeration, the relative size of its structure is with actual different.
With reference to Fig. 6 and Fig. 7 embodiments of the invention are described.
Fig. 6 is the key diagram of the transverse section of the embodiment 1 of employed liquid crystal utensil in the expression injection equipment of the present invention.
As shown in the figure, slot part 10D reduces position 11 by hydrophobicity and has formed side and the bottom surface that constitutes the slot part inner face.Improve the water wettability that hydrophobicity reduces position 11 by for example Corona discharge Treatment.Corona discharge Treatment can be used to the surface modification of formed products etc. in a lot of fields.
On the other hand, on the side of slot part 10D, the last ora terminalis 10E of the groove inboard of opening portion is covered on the Teflon (registered trademark) by the top 10U of liquid crystal utensil 10 above forming.But,, therefore can hinder the growth of the bubble in slot part 10D because that the inner face of slot part 10D has been processed into is hydrophilic.
Fig. 7 is the transverse section key diagram when having stored liquid crystal 20 among the slot part 10D at the liquid crystal utensil 10 of Fig. 6.Because on liquid crystal utensil 10 among the 10U, comprise that ora terminalis 10E all is hydrophobic at interior upper surface on the slot part medial surface of slot part 10D, the liquid crystal 20 that therefore has been stored among the slot part 10D can be deposited in the top fully.
In Fig. 8～Figure 10, the injection equipment when using the liquid crystal utensil of inventing 10 in order more easily to understand compares itself and existing injection equipment.
In Fig. 8, in the chamber 30 that is in vacuum state, shown the elevating mechanism 32 of display panels 31 with inlet 33 and the liquid crystal utensil 10 that on disposing in the above, stores liquid crystal 20.As shown in the figure, liquid crystal utensil 10 is the containers that stored liquid crystal 20 in injection equipment in advance, has used Teflon as material.Therefore, the character that the surface tension that makes the liquid crystal 20 that contacts with lyophoby crystallinity material with the hydrophobicity of liquid crystal utensil 10 that lyophoby crystallinity material is had improves obtains performance.That is, liquid crystal utensil 10 is piled up liquid crystal 20 by the hydrophobicity of itself and the surface tension of liquid crystal from the upper surface of liquid crystal utensil 10.
Under this state, even carry out the deaeration operation, as mentioned above, be hydrophobic because the hydrophobicity of the side that is positioned at the inner face that forms slot part 10D of liquid crystal utensil 10 and bottom surface reduces position 11, therefore can not produce bubble space and bubble in liquid crystal 20 inside.
In Fig. 9, shown state from Fig. 8, in the chamber 30 that is in vacuum state, use elevating mechanism 32 that liquid crystal utensil 10 is risen towards the direction of panel 31, and the lower surface state of contact of the upper surface of liquid crystal utensil 10 and panel 31.Liquid crystal 20 begins to pile up from the upper surface of liquid crystal utensil 10.The injection port 33 of panel 31 is positioned at the middle position of the slot part 10D (Fig. 6) of liquid crystal utensil 10.Therefore, by this contact, a spot of liquid crystal 20 attracted to the inside of panel 31 from inlet 33 by capillarity.Under this state, can not form the space in the inside of liquid crystal 20.Therefore, can not produce such as bad in the injection of the such liquid crystal 20 of panel 31 inner entrained gases.Then, the air pressure in chamber 30 get back to atmospheric during, liquid crystal 20 utilizes pressure reduction and capillarity effect to attracted to the inboard of panel 31 gradually.Consequently, liquid crystal 20 is full of panel 31 inside separately.
Figure 10 is the cross sectional illustration figure from top view with respect to Fig. 9, observes the side illustration figure of a plurality of panels 31 from the side.
Owing to adopted such structure, in above-mentioned action,, in liquid crystal 20, do not found the growth of bubble and the generation in space, and liquid crystal 20 can be filled into panel 31 inside in the inside of the slot part 10D of liquid crystal utensil 10 (Fig. 6).Therefore, the liquid breaking state in the time of can avoiding liquid crystal to inject.Like this, can further improve the utilization ratio of expensive liquid crystal material.
In the above description, as being reduced in the side that forms the slot part inner face and the hydrophobic processing on the bottom surface, enforcement be to improve hydrophilic Corona discharge Treatment, but also can be concavo-convex in the formation of slot part surface by blasting treatment, milled processed.In concavo-convex generation, comprise processing such as generating linearity muscle, toroidal muscle.
With reference to Figure 11 embodiments of the invention 2 are described.
In the embodiment 2 of Figure 11, be coated with Teflon (registered trademark) 10A on the surface of the underlying metal 12 of liquid crystal utensil 10.Underlying metal 12 uses aluminium, stainless steel (SUS) etc. usually.Liquid crystal can cause polluting with contacting of metal.Therefore, the enforcement of the hydrophobic processing of above-mentioned reduction must guarantee at least promptly to form on the side and bottom surface of groove inner face at the surface of contact of liquid crystal, can not expose underlying metal 12.
Therefore, when liquid crystal utensil has the coating that hydrophobic material constitutes on its underlying metal surface, can implement the unexposed processing of underlying metal.For example, concavo-convex when reducing hydrophobic processings in sandblast processing, milled processed etc. by generating on slot part surface, can embodiment as the processing of utilization coating that residual hydrophobic material constituted on the underlying metal surface.In addition, the face that reduces hydrophobic processing is not through exposing underlying metal, and for example such hydrophobic processing of reduction of corona discharge just can be implemented new coating and handle.
Other inscape identical with shown in Fig. 6, it illustrates omission.
By adopting such structure, be very effective aspect the permanance of liquid crystal utensil.
By reducing hydrophobic processing to implementing on the side of the formation slot part inner face in the slot part above the liquid crystal utensil of hydrophobic material and the bottom surface, the generation of the bubble of the liquid crystal inside that can easily suppress to be stored.Therefore, be applicable to as liquid crystal, have viscosity, the injection device of liquid that surface tension is big, promptly utilize capillarity etc. to inject the purposes that this class must suppress the generation of bubble from inlet.
