Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
In order to make liquid crystal, in the liquid crystal cell 100 of present embodiment, be provided with N separately in its four corners more easily to the diffusion of the corner of liquid crystal cell
i(i=1,2,3,4, N
i>=1) the individual wall formula body 102 that is used for liquid crystal 101 is drained into four corners.This wall formula body 102 is divided into N with two frames in its corner, place with the corner
iThe structure of+1 drainage trough 103.
As shown in Figure 1, it (is N that the every nook and cranny is provided with 4
1=N
2=N
3=N
4=4) wall formula body 102.In order liquid crystal 101 to be guided into four corners, as shown in Figure 2, the arragement direction of 4 wall formula bodies is along the dispersal direction (direction of arrow among Fig. 2) of liquid crystal, is that the center is fan shape and arranges with the summit at the angle in corner, place promptly.4 wall formula bodies can form 5 drainage troughs 103 together with the frame of liquid crystal cell 100.Because drainage trough 103 is the shape of funnel, its big mouthful direction of coming towards liquid crystal 101 diffusions, its osculum has quickened the speed of liquid crystal 101 to the corner diffusion like this towards the corner, has avoided four jiaos of underfill phenomenons of liquid crystal cell 100.
Further, the length the closer to the wall formula body at liquid crystal cell edge in the wall formula body is more little, promptly is in the wall formula body that fan shape arranges, and middle wall formula body length is greater than the wall formula body length on both sides.In Fig. 1; The length of two wall formula bodies that is positioned at fan-shaped centre is longer than the wall formula body on both sides; Liquid crystal 101 with liquid crystal cell 100 middle parts is directed to the corner so more easily; When avoiding four jiaos of underfills of liquid crystal cell, also avoided the phenomenon of the liquid crystal overshoot at liquid crystal cell middle part, liquid crystal is distributed equably.
Further, the wall formula body 102 that is the fan shape distribution equates the angle that forms a plurality of drainage troughs 103, makes the liquid crystal 101 of guiding the corner into be evenly distributed.
Because wall formula body is positioned at liquid crystal cell, it highly is less than or equal to the height of chock insulator matter in the liquid crystal cell.The pressure of two substrates not necessarily fully evenly, possibly cause the liquid crystal skewness in corner to box the time, and in order to make liquid crystal in the corner more even distribution, preferably, the height of wall formula body is less than chock insulator matter.Shown in Fig. 3 (a)～(c) and 4 (a)～(c), be the cut-open view in one of them corner of liquid crystal cell among Fig. 1, color membrane substrates 104 becomes liquid crystal cell with array base palte 105 through sealing 107 pairs of boxes of frame glue.The height of wall formula body 102 makes wall formula body 102 and liquid crystal cell 100 that certain gap arranged less than the height of chock insulator matter 106, and behind box, liquid crystal 101 can spread between drainage trough 103 through the space, makes the liquid crystal 101 that is distributed in the corner more even.
As shown in Figure 3, the wall formula body 102 in the liquid crystal cell 100 of present embodiment can be produced on the color membrane substrates 104; As shown in Figure 4, wall formula body 102 also can be produced on the array base palte 105.As shown in Figure 5, also can be positioned on the color membrane substrates 104 by a part of wall formula body 102, another part wall formula body 102 is positioned on the array base palte 105.As shown in Figure 6, the wall formula body 102 of present embodiment can also be divided into the first sub-wall formula body 102a and the second sub-wall formula body 102b, and the first sub-wall formula body 102a and the second sub-wall formula body 102b lay respectively on array base palte 105 and the color membrane substrates 104.
Adhering to wall formula body structure with array base palte is example; When making liquid crystal cell, liquid crystal is dripped on the array base palte by pattern in advance with the formula injection mode of dripping, fluid sealant is coated on the color membrane substrates; With 180 ° of the color membrane substrates upsets that scribbles fluid sealant; With drip liquid crystal is arranged array base palte to box, to hiding active viewing area with mask plate behind the box, with ultraviolet light envelope frame glue is cured then.Fig. 2 shows as the diffusion process to liquid crystal behind the box; When liquid crystal by the pressure extrusion of upper and lower base plate to wall formula body structure the time, the distance between the wall formula body of arranging along with fan shape is more and more littler from export-oriented edge, the amount of liquid crystal when not having this structure that can assemble to the amount of liquid crystal of edge is many; And then the vacuum space of filling edge; Reduce the generation of four jiaos of underfill phenomenons, improved accuracy and production efficiency that technological process detects, also improved the quality of liquid crystal cell.During the utility model is particularly useful for, the manufacturing of large scale or oversize liquid crystal panel.
Present embodiment also provides a kind of liquid crystal indicator; The liquid crystal cell of this liquid crystal indicator is the liquid crystal cell that above-mentioned corner is provided with wall formula body; The length of the number of wall formula body and wall formula body is along with the size of liquid crystal indicator is different and different in its liquid crystal cell; The liquid crystal indicator that general size is big more, the wall formula body number in its liquid crystal cell is many more, and wall formula body length is longer.
Because the corner of the liquid crystal cell of liquid crystal indicator is provided with wall formula body; Liquid crystal is more concentrated to the diffusion of four corners of liquid crystal cell; Avoided the phenomenon of middle overshoot four jiaos of underfills appearred and in the liquid crystal cell after box and the heat curing, improved the quality of liquid crystal indicator on the whole.
Above embodiment only is used to explain the utility model; And be not the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be defined by the claims.
