Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention。
The embodiment of the present invention provides a kind of liquid crystal panel, as depicted in figs. 1 and 2, including the sealed plastic box 3 of the first substrate 1 being oppositely arranged, second substrate 2 and the outer peripheral areas being positioned at described first substrate 1 and described second substrate 2, described first substrate 1 includes the first barrier layer 4 against the medial wall of described sealed plastic box 3。
In embodiments of the present invention, first barrier layer 4 is against the medial wall of described sealed plastic box 3, namely the one side of the first barrier layer 4 contacts with the medial wall of sealed plastic box 3 so that sealed plastic box 3 only has sub-fraction and is likely to be exposed liquid crystal, greatly reduces liquid crystal and touches the probability of not completely crued sealed plastic box 3。Thus reducing the probability that image retention occurs, improve the experience of user。
Further, as shown in Figure 3 and Figure 4, described second substrate 2 also includes at least one and is positioned at the second barrier layer 5 inside described sealed plastic box 3, between described second barrier layer 5 and described sealed plastic box 3, there is certain intervals, wherein, the thickness of described second barrier layer 5 is less than the thickness of described first barrier layer 4。
Less the second barrier layer 5 of thickness and first substrate 1 and second substrate 2 form the fold-line-shaped passage of liquid crystal, it is possible to decrease the speed of liquid crystal diffusion between first substrate 1 and second substrate 2 and do not affect the narrow frame design of TFT-LCD。
Simultaneously, thickness first barrier layer 4 bigger than the second barrier layer 5 is against sealed plastic box 3, making sealed plastic box 3 only have small part region and be likely to be exposed liquid crystal, the cooperation of the first barrier layer 4 and the second barrier layer 5 can reduce liquid crystal better and touch the probability of not completely crued sealed plastic box 3。
Wherein, the interval between the second barrier layer 5 and described sealed plastic box 3 can be arranged according to practical situation, and, same second barrier layer 5 interval everywhere and between sealed plastic box 3 can be different, but to prevent the second barrier layer 5 from contacting with the first barrier layer 4。
It should be noted that the thickness of the first barrier layer 4 should be relatively big, otherwise sealed plastic box 3 is likely to be squeezed, spread through the first barrier layer 4 that thickness low LCL is big, cause that the first barrier layer 4 lost efficacy when first substrate 1 and second substrate 2 are to box。
In the present embodiment, owing to the thickness of the first barrier layer 4 is relatively big, thus one layer is only arranged；And the thickness of the second barrier layer 5 on second substrate is less, it is preferred that 3-5 layer can be arranged, so neither affects the narrow frame of the TFT-LCD being made up of this substrate, may also function as the effect of the diffusion velocity well slowing down liquid crystal simultaneously。
For reducing liquid crystal diffusion velocity between first substrate 1 and second substrate 2, described first substrate 1 may also include at least one and is positioned at the 3rd barrier layer 6 inside described sealed plastic box 3, similar with the second barrier layer 5, the thickness of described 3rd barrier layer 6 is less than the thickness of described first barrier layer 4。Concrete, the 3rd barrier layer 6 that first substrate 1 has may also preferably be 3-5 layer, and the 3rd barrier layer 6 on first substrate 1 can be parallel to each other arranged in a crossed manner with the second barrier layer 5 on second substrate 2, as shown in Figure 5 and Figure 6。It was verified that the time that the image retention of this liquid crystal panel disappears is 3-5 minute, relative to other liquid crystal panels, the time that image retention disappears at least shortens 30%。
Simultaneously, as illustrated in fig. 4 or 6, the height of described first barrier layer 4, the height of described second barrier layer 5 and the height of described 3rd barrier layer 6 less than first substrate 1 and second substrate 2 to the distance after box, the height of described first barrier layer 4, in the height of described second barrier layer 5 and the height three of described 3rd barrier layer 6 arbitrarily both sums more than first substrate 1 and second substrate 2 to the distance after box, make the first barrier layer 4, between 3rd barrier layer 6 and second substrate 2, second barrier layer 5 and first substrate 1, all there is between second substrate 2 certain gap, the liquid crystal being diffused into outer peripheral areas is conducive to be back to the viewing area (Fig. 1 in the middle of liquid crystal panel, the broken box of 3 or 5) in。If liquid crystal panel is under the impact being subject to external condition, during as being subject to the effects such as high temperature, beating or extruding, liquid crystal panel is it may happen that deformation, and the liquid crystal in viewing area can be diffused in outer peripheral areas by gap；After affecting the external condition disappearance that liquid crystal panel deforms upon, the external force such as room temperature, beating or extruding it are down to when cancelling such as temperature, the partial liquid crystal that outer peripheral areas leaves can be back in viewing area by these gaps again, liquid crystal total amount in the liquid crystal display area of liquid crystal panel is remained unchanged, thus being conducive to improving the product quality of liquid crystal panel and stablizing of display characteristic。
Concrete, material for forming the first barrier layer 4 and/or the second barrier layer 5 may include that transparent or opaque resin material or other nonmetallic materials。General, if this substrate is color membrane substrates, this first barrier layer 4 and/or the second barrier layer 5 can be one-body molded with the chock insulator matter on substrate, black matrix even color resin；Similar, if this substrate is array base palte, this first barrier layer 4 and/or the second barrier layer 5 can be one-body molded with the chock insulator matter on substrate。
Further, as it is shown in fig. 7, described first barrier layer 4 can have multiple groove 7 away from the one side of described first substrate 1。When liquid crystal diffuses to the first barrier layer 4, initially enter multiple grooves 7 of the first barrier layer 4, just may proceed to after filling up groove 7 spread to sealed plastic box 3 direction, extend liquid crystal and touch the time of sealed plastic box 3, reduce liquid crystal and touch the probability of completely not uncured sealed plastic box 3。Wherein, this groove 7 conveniently of circular shape, rectangle, rhombus, irregularly shaped etc. also can, the degree of depth can be configured according to practical situation, it is preferred that as shown in Figure 8, and the degree of depth of described groove 7 is the 1/5 to 1/3 of the height of the first barrier layer 4。
In the present embodiment, the thickness of the first barrier layer 4 and the second barrier layer 5 all arbitrarily can be arranged according to practical situation, but to ensure the thickness thickness more than the second barrier layer 5 of the first barrier layer 4。Preferably the thickness of described first barrier layer 4 is 50-1000 micron, and the thickness of described second barrier layer 5 is 1-50 micron, for instance, the thickness of the first barrier layer 4 is 300 microns, and the thickness of the second barrier layer 5 is 15 microns。
Similar, such as Fig. 1, shown in 3 or 5, described first barrier layer 4 and/or described second barrier layer 5 are rectangle, owing to sealed plastic box 3 is generally round rectangle, in order to improve the fiting effect between the first barrier layer 4 and sealed plastic box 3, the first preferred round rectangle corresponding with sealed plastic box 3 of barrier layer 4, generally, the shape of the first barrier layer 4 is consistent with sealed plastic box 3, to improve the fiting effect of the first barrier layer 4 and sealed plastic box 3。
Accordingly, the second barrier layer 5 is alternatively rectangle or round rectangle。Additionally, the second barrier layer 5 is alternatively other shapes, for instance rhombus, parallelogram etc.。
Generally, liquid crystal is that the center from substrate starts uniformly to spread to surrounding, if the second barrier layer 5 is rectangle or round rectangle, owing to the corner of the second barrier layer 5 is for the remainder of the second barrier layer 5, the center of distance liquid crystal diffusion is farthest, so liquid crystal arrive the fillet place of the second barrier layer 5 needed for time the longest, in this place's liquid crystal contact, the probability of not completely crued sealed plastic box 3 is only small, so opening can be provided with at described second barrier layer 5, particularly in fillet place, opening is set, as shown in Figure 9, this opening is conducive to the liquid crystal backflow flowed outside the second barrier layer 5 because liquid crystal panel is subject to external force, ensure the display effect of liquid crystal panel。
