Embodiment
With reference to Fig. 2 a, it shows the liquid crystal utensil 100 of first embodiment of the invention, this liquid crystal utensil 100 comprises a body 101, and body 101 comprises one first side surface 110, one second side surface 120, one the 3rd side surface 130, one the 4th side surface 140, a loading end 150 and a basal surface 160.This loading end 150 is in contrast to this basal surface 160.This first side surface 110, this second side surface 120, the 3rd side surface 130 and the 4th side surface 140 are in abutting connection with this loading end 150 and this basal surface 160.
With reference to Fig. 2 b, when carrying out the liquid crystal implantation step, at first, liquid crystal material 14 can drop on the loading end 150.At this loading end is made definition, among embodiments of the invention and claim, loading end is defined as: when the dispenser method material, the whole surface that contacts with liquid crystal material, promptly, it was meant before this liquid crystal utensil contacts this panel, all surface that this liquid crystal utensil contacts with liquid crystal material.This loading end 150 is a whole plane, at this whole plane is made definition, and among embodiments of the invention and claim, whole plane is defined as: the plane that does not have any groove, depressed part or lug boss.Because loading end 150 is a whole plane, therefore, in the time of on liquid crystal material 14 is positioned at this loading end 150, can have sufficient surface tension, reduce the situation of liquid crystal material overflow.And, because loading end 150 does not have depressed part, so can save the use amount of liquid crystal.
With reference to Fig. 2 c, after the loading end 150 of panel 2 contact liquid crystal utensils 100, liquid crystal material 14 will be by among the capillarity suction panel 2.
In existing Design Thinking, can't adopt liquid crystal utensil of the present invention to carry out liquid crystal injects, its reason is, with reference to Fig. 3 a, assert in existing Design Thinking, when loading end 150 is whole plane, because the side of panel 2 also is the plane, in the time of therefore on panel places liquid crystal utensil, the side of panel 2 will closely contact with loading end 150, and liquid crystal material 14 is pushed away loading end 150, do not inject panel 2 so do not have sufficient liquid crystal material.Yet, in fact, with reference to Fig. 3 b, it is the A part enlarged drawing among the displayed map 2c, and the side of panel 2 is because the irregular factor of cutting, so irregular structure of meeting tool, simultaneously, arrange in pairs or groups the dimensional tolerence during owing to cutting with reference to Fig. 3 c, in fact the side of panel 2 is not fully perpendicular to its principal plane (advancing light face and exiting surface), so in fact the side of panel 2 has an angle with loading end 150 when contacting.Comprehensive above factor, in the liquid crystal injection process, the side of panel 2 in fact and can't closely contact with loading end 150, so the side of panel 2 and loading end 150 have liquid crystal material that the space holds abundance for flowing among this panel 2.
Use liquid crystal utensil of the present invention, can reduce the use amount of liquid crystal material in a large number, with reference to table 1, it is the liquid crystal panel that shows at various different sizes, the liquid crystal material amount ratio of liquid crystal utensil of the present invention and prior art:
The liquid crystal material amount ratio of table 1 liquid crystal utensil of the present invention and prior art

As shown in Table 1, liquid crystal utensil of the present invention can be saved the use amount of liquid crystal material really, and has directly avoided in the prior art, the problem that liquid crystal material is aging.
With reference to Fig. 4, its be the liquid crystal utensil 100 that shows the second embodiment of the present invention ', it has guide groove 102, in order to the liquid crystal material of guiding overflow, in a second embodiment, body 101 ' its section is to be the convex shape structure.Same, in a second embodiment, loading end 150 (before this liquid crystal utensil contacts this panel, all surface that this liquid crystal utensil contacts with liquid crystal material) is a whole plane.
With reference to Fig. 5, it is the liquid crystal utensil 100 that shows the third embodiment of the present invention ", it has guide groove 103, and in order to the liquid crystal material of guiding overflow, in the 3rd embodiment, " its section is to be ladder-type structure to body 101.Same, in the 3rd embodiment, loading end 150 (before this liquid crystal utensil contacts this panel, all surface that this liquid crystal utensil contacts with liquid crystal material) is a whole plane.
With reference to Fig. 6, it is the liquid crystal utensil 200 that shows the fourth embodiment of the present invention, and its characteristics are that this liquid crystal utensil 200 more comprises a joint portion 210, be formed at this body 101 ' the bottom, in order to combine with a perfusion liquid crystal apparatus.The volume of this joint portion 210 less than this body 101 ', and two sides of this joint portion are formed with a grasping part.Above-mentioned joint portion can be used with aforementioned arbitrary liquid crystal utensil collocation.
With reference to Fig. 7, it shows the actual operating position of liquid crystal utensil of the present invention, is example at this liquid crystal utensil 200 with the 4th embodiment.When injecting liquid crystal, liquid crystal utensil 200 is embedded on the locating piece 300.
With reference to Fig. 8, the process that liquid crystal injects is below described, in the present invention, the process that liquid crystal injects is to carry out in a cavity.At first, can vacuumize (S1) earlier in this cavity.Then, panel can contact the liquid crystal material on this liquid crystal utensil, injects (S2) to carry out liquid crystal.At last, the pressure in this cavity recovers normal pressure, and liquid crystal injects finishes (S3).
With reference to Fig. 9 a and Fig. 9 b, it is the situation that shows liquid crystal utensil 200 carrying liquid crystal materials 14, and wherein, the liquid crystal utensil 200 among Fig. 9 a and Fig. 9 b is the liquid crystal utensil of same size and form.At first with reference to Fig. 9 a figure, the liquid crystal bearing capacity of liquid crystal utensil 200 has a maximal value, and for example, in this embodiment, the maximum bearing capacity of this liquid crystal utensil 200 is about 5 grams.Yet, in the processing procedure of reality, only restrain less than 1 owing to need flow into the requirement of the liquid crystal material of panel.Make an addition to liquid crystal material amount on this loading end and the ratio between the actual use amount and be about 3: 1 to 5: 1, the liquid crystal material that for example flows into panel is 0.3 gram, then make an addition to liquid crystal material on the loading end and can be arbitrary numerical value in the 0.9-1.5 gram, 0.9 gram, 1.0 grams, 1.2 grams, 1.5 grams etc.Therefore, in the processing procedure of reality, the liquid crystal material that makes an addition to this liquid crystal utensil 200 only is 3 grams, so can finish the step that liquid crystal injects smoothly.Therefore, in actual processing procedure, making an addition to the liquid crystal material amount of liquid crystal utensil, is to measure according to the actual requirements and decide, and might not need to be added to the maximum bearing capacity of liquid crystal utensil.
Though the present invention discloses with specific embodiment; but it is not in order to limit the present invention; any those skilled in the art; the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present invention and scope, having done; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that scope of patent protection of the present invention is done.
