See also Fig. 4, it is employed a kind of frame glue solidify device in the liquid crystal panel manufacture process of the present invention, this frame glue solidify device 9 comprises an operating platform 800, second substrate 200 of liquid crystal panel is positioned on this operating platform 800, between second substrate 200 of this operating platform 800 and liquid crystal panel, have a plurality of feets 600, regulating device (figure does not show) is regulated the height of these a plurality of feets 600, this feet 600 is used in 200 supports of second substrate high, contiguous feet 600 1 sides have a reflecting surface 801 on this operating platform 800, also be provided with a reflex reflector 150 (consulting Fig. 6) in the outside of this operating platform 800 and second substrate 200, be used for light reflection ultraviolet.
This feet 600 makes ultraviolet light fully shine frame glue in UV-irradiation frame glue process and makes it reach required hardenability in liquid crystal panel manufacture process.
Seeing also Fig. 5 and Fig. 6, is the manufacture method first embodiment synoptic diagram of liquid crystal panel and the method for frame adhesive curing of the present invention.Liquid crystal panel 2 comprises first substrate 100, frame glue 700, liquid crystal 500 and second substrate 200.These first substrate, 100 surfaces are placed with a plurality of photoresistances 400 and black matrix 300.The manufacture method of liquid crystal panel of the present invention comprises the steps: at first, and first substrate 100 and second substrate 200 are provided, and forms photoresistance 400 and black matrix 300 on first substrate 100, and coating frame glue 700; Secondly, dispenser method 500 on second substrate 200, liquid crystal 500 is the liquid crystal compounds that are made of liquid crystal material and sept, a side of superimposed second substrate 200 with liquid crystal 500 and have a side of first substrate 100 of photoresistance 400, black matrix 300 and frame glue 700 under vacuum state; At last, on first substrate 100, use UV-irradiation frame glue 700 so that its sclerosis.
The method for curing process of frame glue 700 is as follows: the liquid crystal panel after superimposed 2 is placed on the feet 600 of operating platform 800, this feet 600 is arranged on this operating platform 800, regulating device (figure does not show) can be regulated the height of these a plurality of feets 600, contiguous feet 600 1 sides have a reflecting surface 801 on this operating platform 800, has a reflex reflector 150 at this operating platform 800 with second substrate, 200 sides vertical these reflecting surface 801 directions of one side, the shape of this reflex reflector 150 is to cooperate ultraviolet light that it is fully imported to expose on the frame glue 700, its shape can be a linear, also arc.When this first substrate 100 of UV-irradiation, the part UV-irradiation is arranged on this reflex reflector 150, reflex on the reflecting surface 801 through this reflex reflector 150, after penetrate second substrate 200 through this reflecting surface 801 reflection back ultraviolet lights, be radiated on the frame glue 700 that is positioned under the black matrix of liquid crystal panel, make its sclerosis.Also have partly that ultraviolet light is directly to penetrate first substrate 100, be radiated at not on the frame glue 700 that is blocked by black matrix 300, make its sclerosis.
Compared to prior art, because in the processing procedure of LCD panel manufacturing method of the present invention, when carrying out UV-irradiation frame glue 700, mirror process is made by the original black surface that absorbs ultraviolet light easily in the surface of operating platform 800, make from the ultraviolet light of its surperficial incident and can reflect away fully, in addition, between second substrate 200 and operating platform 800, be provided with a plurality of feets 600, this feet 600 is high with 200 supports of second substrate, regulate the height of this feet 600, ultraviolet light after process reflex reflector 150 reflects can be reflected on the abundant frame glue 700 that shines under the black matrix 300 in back through reflecting surface 801, therefore can make the 700 abundant sclerosis of frame glue and can not pollute liquid crystal, thereby improve the production yield of product, improve product quality.
Seeing also Fig. 7 and Fig. 8, is the manufacture method second embodiment synoptic diagram of liquid crystal panel of the present invention.The liquid crystal panel 3 that the present invention makes, it comprises first substrate 110, frame glue 710, liquid crystal 510 and second substrate 210.These first substrate, 110 surfaces are placed with a plurality of photoresistances 410 and black matrix 310.
The manufacture method of liquid crystal panel of the present invention comprises the steps: at first, and first substrate 110 and second substrate 210 are provided, and forms photoresistance 410 and black matrix 310 on first substrate 110; Secondly, coating frame glue 710 on second substrate 210, dispenser method 510 on second substrate 210 again, liquid crystal 510 is the liquid crystal compounds that are made of liquid crystal material and sept, this frame glue 710 all be positioned at black matrix 310 below, a side of superimposed second substrate 210 with liquid crystal 510 and frame glue 710 and have a side of first substrate 110 of photoresistance 410, black matrix 310 under vacuum state; At last, on first substrate 110, use UV-irradiation frame glue 710 so that its sclerosis.Has an operating platform 810 in 3 times close second substrate, 210 1 sides of this liquid crystal panel, its surface is a reflecting surface 811, between this operating platform 810 and second substrate 210, have a plurality of feets 610, regulating device (figure does not show) can be regulated the height of these a plurality of feets 610, close second substrate, 210 1 sides at this operating platform 810 have a reflex reflector 160, when this first substrate 110 of UV-irradiation, the part UV-irradiation is arranged on this reflex reflector 160, reflex on the reflecting surface 811 through this reflex reflector 160, after penetrate second substrate 210 through this reflecting surface 811 reflection back ultraviolet lights and be radiated on the frame glue 710, thus, ultraviolet light shines this frame glue 710 by all directions and makes it finally reach needed hardenability.
According to experiment relatively, when first substrate, one side irradiating ultraviolet light, second substrate directly lies on the operating platform with the use feet that the frame glue hardening ratio that the high back of second substrate support is reached is as shown in the table.
| Feet height (m) | Ultraviolet light radiant quantity (the J/m that exposes to the sun 2) | Frame glue hardening ratio (%) |
| Frame segment glue is positioned under the black matrix | ||
| 0 | 20000 | 50 |
| 0.0023 | 20000 | 59 |
| 0.0023 | 40000 | 62 |
As seen from the above table: in carrying out the UV-irradiation process, the expose to the sun hardening ratio of effect of altitude frame glue of radiant quantity and feet of ultraviolet light, the liftable height of feet is the highest to be 0.0023m, the ultraviolet light radiant quantity of exposing to the sun is 20000～40000J/m
2, be 0.0023m wherein at the feet height, the ultraviolet light radiant quantity of exposing to the sun is 40000J/m
