Embodiment
Fig. 1 is the vertical view of the display panels of a preferred embodiment of the present invention, and Fig. 2 is along the partial cutaway schematic of A-A ' line among Fig. 1.Please jointly with reference to Fig. 1 and Fig. 2, display panels 100 comprises substrate 110, another substrate 120, liquid crystal layer 130, patterning spaced walls 140 and glue frame 150, and wherein substrate 110 for example has viewing area 114 and the non-display area 112 that is centered around outside the viewing area 114.In one embodiment, substrate 110 for example is an active elements array substrates, and active elements array substrates can be thin film transistor (TFT) (ThinFilm Transistor, TFT) array base palte or diode (Diode) array base palte.
120 of another substrates are arranged on the substrate 110, and substrate 120 for example is a colored optical filtering substrates, be provided with a plurality of redness, green and blue filter coating (not marking among the figure) on this substrate 120, and these filter coatings are the dot structure on the counterpart substrate 110 separately, makes display panels 100 can show the picture of full-colorization.In another embodiment, substrate 110 can be a colored optical filtering substrates, and substrate 120 can be an active elements array substrates.
In addition, black matrix layer 170 can be set also on the display panels 100, it is between the non-display area 112 and substrate 120 of substrate 110, and black matrix layer 170 is between patterning spaced walls 140 and substrate 110.Because black matrix layer 170 is around viewing area 114, therefore black matrix layer 170 also can be improved the problem of light leak and the contrast (Contrast) that increases display panels 100.
In one embodiment, substrate 110 is that a color filter film is produced on the thin film transistor (TFT) array that (at this moment, black matrix layer 170 can be made on the COA substrate for Color Filter On Array, substrate COA), and substrate 120 is glass substrates.In another embodiment, substrate 110 is active elements array substrates, and substrate 120 is colored optical filtering substrates, and at this moment, black matrix layer 170 can be made on the colored optical filtering substrates.
Please continue with reference to Fig. 1 and Fig. 2, patterning spaced walls 140 for example has spaced walls 142, spaced walls 144 and a plurality of spaced walls 146.Wherein, spaced walls 142 is around liquid crystal layer 130, and another spaced walls 144 is around spaced walls 142.Spaced walls 144 and spaced walls 142 gap d 1 of being separated by, and this gap d1 for example is 5 μ m.In addition, these spaced walls 146 can be to be arranged between spaced walls 142 and another spaced walls 144 with constant spacing, it is separated the space in the gap d 1, and spaced walls 142, spaced walls 144, spaced walls 146, substrate 110 and substrate 120 define liquid crystal storage area 160a, 160b, 160c.
The plan view shape of spaced walls 142,144 for example is a rectangle.And as shown in Figure 1, spaced walls 142,144 itself has a width d2, and the width d2 of spaced walls 142,144 for example is 2 μ m.The length of each spaced walls 146 is d3, and its width is d1 (being gap d 1), and wherein length d 3 for example is 2 μ m, and width d1 for example is 5 μ m.What deserves to be mentioned is, change the width d2 of above-mentioned gap d 1, spaced walls 142,144, or the length d 3 of spaced walls 146 just can change the volume of liquid crystal storage area 160a, 160b, 160c.In addition, the plan view shape of spaced walls 142,144 is not limited to rectangle shown in Figure 1, and it for example also can be circular, oval or other polygon.
The material of patterning spaced walls 140 can be a photoresist, so patterning spaced walls 140 can cooperate known photoetching process to make.In addition, because patterning spaced walls 140 is not to be arranged in viewing area 114, therefore can not have influence on the quality of display frame.What deserves to be mentioned is, when the phenomenon of liquid crystal skewness appears in display panels 100, can repair for this display panels 100.The method for repairing and mending of this kind display panels below will be described.
When liquid crystal skewness phenomenon appearred in display panels 100, this method for repairing and mending for example was to remove partially patterned spaced walls 140, so that excessive liquid crystal imports among liquid crystal storage area 160a, 160b, the 160c.In addition, the method that removes partially patterned spaced walls 140 is to utilize laser, and wherein employed Wavelength of Laser for example is positioned at ultraviolet light zone (Ultra-Violet), and employed energy for example is 0.1mJ.
Fig. 3 is along the partial cutaway schematic of B-B ' profile line among Fig. 1.Please refer to Fig. 3, more specifically, the step of method for repairing and mending is as described below.At first, measure normal region 184 and liquid crystal skewness zone 182 gap width d5, d4 separately, wherein gap width d5, d4 are the distance between substrate 110 and the substrate 120.
Then, measure the area in liquid crystal skewness zone 182 as shown in Figure 1.Come, calculate the volume of too much amount of liquid crystal, the volume of this too much amount of liquid crystal is (area in liquid crystal skewness zone 182) * (the gap width d5 of the gap width d4-normal region 184 in liquid crystal skewness zone 182).Afterwards, according to the volume of too much amount of liquid crystal, decision will remove the patterning spaced walls 140 of how much quantity, to discharge enough liquid crystal storage area 160a, 160b, 160c again.
Please continue with reference to Fig. 1, generally speaking, because display panels 100 is uprightly in use and puts, so liquid crystal can be subjected to the influence of gravity, and is concentrated in the below of display panels 100 mostly.So, can remove the spaced walls 142 of the lower right corner or position, the lower left corner earlier, and make liquid crystal storage area 160a hold excessive liquid crystal.Afterwards, can reevaluate whether will continue to remove and be positioned at the up and down spaced walls 142 in two side centre positions, to open liquid crystal storage area 160b.If amount of liquid crystal is still too much, then can continue to remove spaced walls 142 to open liquid crystal storage area 160c.Yet amount of liquid crystal to open liquid crystal storage area 160a, in addition, also can remove the spaced walls 146 of part, so that conducting each other between the liquid crystal storage area 160a, 160b, 160c if serious mistake can be cut the spaced walls 142 that is positioned at four corners at most in advance.
In sum, the present invention's the display panels and the method for repairing and mending of display panels have following advantage:
One, the present invention's display panels is provided with the patterning spaced walls at non-display area, and has a plurality of liquid crystal storage area in the patterning spaced walls.This patterning spaced walls because be not the position in the viewing area, therefore can not have influence on the quality of display frame.
Two, when the situation of liquid crystal skewness occurs, the removable portion spaced walls is to open the liquid crystal storage area, and thus, liquid crystal just can flow in the liquid crystal storage area, makes to show that undesired zone can dwindle or disappear.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; any person of ordinary skill in the field; without departing from the spirit and scope of the invention; when can doing a little change and improvement, so the present invention's protection domain attached claim person of defining after looking is as the criterion.
