The present invention discloses a kind of frame adhesive curing method, and it may further comprise the steps: a liquid crystal panel is provided; Make ultraviolet light by the frame glue with this liquid crystal panel of irradiation behind the shade of slit pattern, make its curing.The present invention also discloses a kind of manufacture method of liquid crystal panel, and it adopts above-mentioned frame adhesive curing method to solidify frame glue.
Description
[technical field]
The invention relates to a kind of frame adhesive curing method and a kind of LCD panel manufacturing method that adopts this frame adhesive curing method to solidify frame glue.
[background technology]
Liquid crystal panel is the critical piece of liquid crystal indicator, and it comprises one first substrate, one second substrate, a liquid crystal layer that is sandwiched between two substrates, and this first substrate and this second substrate fit tightly by a frame glue.The method for implanting of liquid crystal generally can be divided into vacuum suction and drip formula (One Drop Fill, ODF) two kinds.Vacuum suction is to utilize the capillary principle that liquid crystal is sucked after first substrate and second substrate are to group, this method length consuming time, and cause the waste of liquid crystal material easily.The formula of dripping is earlier liquid crystal directly to be dropped on the substrate, and then carry out substrate to group, this method can significantly be saved time and the liquid crystal material that injects liquid crystal, especially has more advantage in the large size panel manufacture method.
Seeing also Fig. 1, is the structural representation of prior art liquid crystal panel.Liquid crystal panel 1 comprises one first substrate 10, one second substrate 20, is sandwiched in liquid crystal 50 and a frame glue 70 between two substrates, wherein, this frame glue 70 fits tightly this first substrate 10 and this second substrate 20, these first substrate, 10 inside surfaces arrange a plurality of photoresistances 40 and black matrix 30.
Fig. 2 and Fig. 3 are first substrate 10 and second substrate, 20 applying process synoptic diagram among Fig. 1.At first, provide one first substrate 10 and one second substrate 20, on this first substrate 10, form photoresistance 40 and black matrix 30 and be coated with frame glue 70; Secondly, dispenser method 50 on this second substrate 20; Superimposed this first substrate 10 of contraposition and this second substrate 20 under vacuum state then; At last, by ultraviolet light (Ultra Violet, thus UV) irradiation frame glue 70 forms liquid crystal panel 1 so that its curing fits tightly this two substrate 10,20.
Above-mentioned frame glue 70 solidification processs are earlier liquid crystal panel 1 to be placed on the operating platform 80, make its curing by UV-irradiation frame glue 70 again.In carrying out the UV-irradiation process, because the A of frame glue 70 part position is in black matrix 30 times, ultraviolet light is caused the state of cure deficiency of frame glue 70 easily by the black matrix 30 A part that can't shine frame glue 70 of blocking, can not full solidification.And in the solidification process, frame glue 70 directly contacts with liquid crystal 50, thereby liquid crystal 50 causes liquid crystal panel 1 frame glue 70 joint place display brightness inhomogeneous if the curing deficiency will produce the free molecule infiltration, influences the display quality of liquid crystal panel 1.
When solidifying frame glue, even frame glue is not blocked by black matrix, ultraviolet light only by the irradiation of first substrate, 10 1 sides, do not concentrate by the ultraviolet light light intensity, be difficult to also guarantee that the ultraviolet light of sufficient intensity makes frame glue full solidification, so still might cause the display characteristic of liquid crystal panel bad.
In addition, when carrying out the panel applying, if ultraviolet light is shone from second substrate, 20 1 sides, thereby also can stop that light beam irradiates arrives frame glue 70 because of being placed with metal wire on second substrate 20, cause part frame glue 70 states of cure not enough easily, not completely crued frame glue 70 contacts with the direct of liquid crystal 50, thereby might cause the display characteristic of product bad with polluting liquid crystal 50.
[summary of the invention]
Thereby cause the bad defective of liquid crystal panel display characteristic in order to overcome the not enough liquid crystal that pollutes easily of prior art LCD panel manufacturing method center adhesive curing, the invention provides a kind of frame adhesive curing method that frame glue is fully solidified.
The present invention also provides a kind of LCD panel manufacturing method that adopts above-mentioned frame adhesive curing method.
The present invention also provides the another kind of LCD panel manufacturing method that adopts above-mentioned frame adhesive curing method.
The technical scheme that technical solution problem of the present invention adopts is: a liquid crystal panel is provided; Make ultraviolet light by the frame glue with this liquid crystal panel of irradiation behind the shade of slit pattern, make its curing.
The present invention adopts the LCD panel manufacturing method of above-mentioned frame adhesive curing method may further comprise the steps: one first substrate is provided, on this first substrate, forms chromatic filter layer and black matrix, and coating frame glue; Provide one second substrate, dispenser method on this second substrate; Superimposed this first substrate and this second substrate; Make incident uv have the frame glue of this liquid crystal panel of irradiation behind the shade of slit pattern, thereby make frame adhesive curing fit this first substrate and this second substrate by one.
The another kind of LCD panel manufacturing method of above-mentioned frame adhesive curing method that adopts of the present invention may further comprise the steps: one first substrate is provided, forms chromatic filter layer and black matrix on this first substrate; Provide one second substrate, coating frame glue and dispenser method on this second substrate; Superimposed this first substrate and this second substrate; Make incident uv by the frame glue with this liquid crystal panel of irradiation behind the shade of slit pattern, make the frame adhesive curing with this first substrate and this second substrate of fitting.
Compare with prior art, the advantage of liquid crystal indicator of the present invention is: in the frame adhesive curing process of the present invention, elder generation is by a shade with slit pattern before making UV-irradiation frame glue, when passing through slit, light beam forms diffraction, the light intensity redistribution, as long as adjust the shade position, the light intensity that light beam is passed through behind the shade is greatly partly shone the purpose that frame glue can realize improving the frame adhesive curing.If use single slit pattern, form single slit diffraction when then ultraviolet light is by shade, can concentrate light energy distribution; If use double slit or stitch diffraction pattern more, intensity maxima can improve four times or seam number square doubly, so in the solidification process, between light beam and frame glue, add single seam, double slit or stitch pattern more, all can improve light utilization efficiency or increase light intensity, the frame glue zone that traditional illuminating method can't be shone is solidified.Therefore, frame adhesive curing method of the present invention can make frame glue fully solidify and not pollute liquid crystal, thereby improves the liquid crystal panel display quality.
