Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Refer to Fig. 3 and Fig. 4, wherein, Fig. 3 is the cross section structure schematic diagram before curved surface liquid crystal panel first embodiment group of the present invention is stood; Fig. 4 is the cross section structure schematic diagram after curved surface liquid crystal panel first embodiment group of the present invention is stood, time bending.
The invention provides a kind of curved surface liquid crystal panel, this curved surface liquid crystal panel comprises first substrate 110, second substrate 120 and separator 100.
Wherein, first substrate 110 can be the one in TFT substrate or CF substrate, and second substrate 120 is the another one in TFT substrate or CF substrate.In curved surface liquid crystal panel, between TFT substrate and CF substrate, also comprise liquid crystal layer, sealed by sealant layer at the edge of TFT substrate and CF substrate.
In the present embodiment, first substrate 110 is CF substrates, and second substrate 120 is TFT substrate.Wherein, TFT substrate deflects for driving the liquid crystal molecule in liquid crystal layer, to select the light through curved surface liquid crystal panel.CF substrate is for realizing colored display, and first substrate 110 comprises a color filter layers, and this color filter layers comprises tactic R, G, B three primary colors coloring units, a black-matrix layer, a transparent conductive film.This black-matrix layer and this three primary colors coloring units arrange separately, be disposed alternately on first substrate 110, for isolating R, G, B three primary colors coloring units in blocking light beam, make display panels have high-contrast and sharpness, it can be made up of resin material.Transparent conductive film covers this black-matrix layer and coloring units surface.In the present embodiment, separator array is arranged on the upper of first substrate 110 discretely.When first substrate 110 and second substrate 120 are fitted, sealant layer according to circumstances can be coated on the periphery of this black-matrix layer, and the application place of sealant layer also can partly overlap with this black-matrix layer position.
Curved surface liquid crystal panel comprises middle part and the end in both sides, middle part, the TFT substrate and the CF substrate that are combined into curved surface liquid crystal panel also have middle part and end, and the middle part of TFT substrate is corresponding with the middle part of CF substrate, the end of TFT substrate is corresponding with the end of CF substrate.
Separator 100 is located between first substrate 110 and second substrate 120, and this separator 100 is for supporting first substrate 110 and second substrate 120.Separator 100 can be column separator, and the area of section of this column separator can be circular or polygon, as triangle, quadrangle, sexangle etc.In the present embodiment, separator 100 is fixed on the inner side of first substrate 110, the height of separator 100 is equal, from the middle part of liquid crystal panel to end, the formation material of separator 100 is different, such as, in the present embodiment, the hardness of separator 100 reduces from the middle part of curved surface liquid crystal panel gradually to end, and to make when curved surface liquid crystal panel bends, the box in the middle part of curved surface liquid crystal panel is thick thick equal with the box of end.Certainly, in other embodiments, can also be that density or other characteristic of separator 100 reduces from the middle part of liquid crystal panel gradually to end, the deformation quantity that the separator 100 equaling the end of bearing less stress with the deformation quantity making the separator 100 at the middle part of bearing larger stress occur occurs.
Particularly, when curved surface liquid crystal panel bends, the stress born in the middle part of curved surface liquid crystal panel and extruding degree are comparatively large, and under larger effect of stress, the deformation quantity of the separator 100 that this kind of material is made is △ h1; The stress that the end of curved surface liquid crystal panel is born and extruding degree less, under less effect of stress, the deformation quantity that the separator 100 of end occurs is △ h2.But, because the middle part from curved surface liquid crystal panel is to end, the formation material of separator 100 is different, and the separator 100 that the middle part of same size and end material are made is when bearing identical stress, the deformation quantity that the separator 100 that end material is made produces is greater than the separator 100 that middle part material is made; In like manner, when the deformation quantity that the separator 100 of the same size be made up of middle part and end material occurs is identical, the stress that the separator 100 that middle part material is made bears is greater than the stress that separator 100 that end material makes bears.Composition graphs 4, the hardness of middle part separator 100 is larger, under curved surface liquid crystal panel bends and bears larger effect of stress, its deformation △ h1 occurred is still smaller, and the hardness of the separator 100 of end is less, make △ h1=△ h2 after curved surface liquid crystal panel is bending, thus maintain the consistency of thickness of curved surface liquid crystal panel.
Be different from prior art, the separator that the present invention makes by being provided with different materials between first substrate and second substrate, less deformation is there is when bearing larger stress to make the separator in the middle part of liquid crystal panel, because the formation material of separator is different, therefore, when described liquid crystal panel bends, the middle part of liquid crystal panel and end are when bearing different stress, separator is after generation deformation, the thickness of described liquid crystal panel can also be made to be consistent, to make the consistency of thickness of whole liquid crystal panel, thus thickness of liquid crystal layer is evenly distributed, light penetration rate is consistent with the response time, and then ensure that liquid crystal panel can clearly show image, improve optics taste, and structure is simple, easy realization.
Refer to Fig. 5, Fig. 5 is the cross section structure schematic diagram before curved surface liquid crystal panel second embodiment group of the present invention is stood.
In the present embodiment, from the middle part of liquid crystal panel to end, the density forming the material of separator 200 reduces gradually, and separator 200 is fixed on first substrate 210, and in the present embodiment, separator 200 is evenly distributed on first substrate 210.The inner surface of second substrate 220 is plane, and from the middle part of curved surface liquid crystal panel to end, the height of separator 200 reduces gradually.
Specifically, the present embodiment is combined with height change the variable density of separator 200, to realize when curved surface liquid crystal panel bends, and the consistency of thickness of curved surface liquid crystal panel.
The middle part of curved surface liquid crystal panel, the density forming the material of separator 200 is larger, larger stress and extruding degree can be born, and, higher at the height of the separator 200 at middle part, it played main supporting role before curved surface liquid crystal panel bends, and namely before curved surface liquid crystal panel bends, namely there occurs larger deformation.And the end of curved surface liquid crystal panel, the density forming the material of separator 200 is less, only can bear relatively little stress and extruding degree, and it is lower at the height of the separator 200 of end, before curved surface liquid crystal panel is bending, the separator 200 of this end may not play a supportive role, or plays a supportive role, but the deformation that the separator 200 that its deformation occurred is less than middle part occurs.When curved surface liquid crystal panel is bending, the separator 200 at middle part there occurs deformation under larger effect of stress, the separator 200 of end also there occurs deformation under less effect of stress, but because the density of the formation material of middle part separator 200 is larger, the height of the separator 200 at middle part is higher, make the height of the separator 200 at middle part after the height after deformation occurring and with the separator 200 of end, deformation occurs consistent, thus ensure that the consistency of thickness of whole curved surface liquid crystal panel, thickness of liquid crystal layer is evenly distributed, light penetration rate is consistent with the response time, and then ensure that liquid crystal panel can clearly show image, improve optics taste.
Refer to Fig. 6, Fig. 6 is the cross section structure schematic diagram before curved surface liquid crystal panel the 3rd embodiment group of the present invention is stood.
In the present embodiment, from the middle part of liquid crystal panel to end, the hardness forming the material of separator 300 reduces gradually, separator 300 is fixed on first substrate 310, the inner surface of second substrate 320 is provided with protrusion 330, from the middle part of curved surface liquid crystal panel to end, the height of protrusion 330 reduces gradually.
For example, protrusion 330 can be made by gray-level mask (GrayToneMask, GTM) technique, and from the middle part of curved surface liquid crystal panel to end, the height of this protrusion 330 reduces gradually.Such as, in the end of curved surface liquid crystal panel, the height reduction of protrusion 330 is zero, namely equal with the inner surface of second substrate 320.
Specifically, the present embodiment is combined the height change of the firmness change of separator 300 with second substrate 320 inner surface protrusion 330, to realize when curved surface liquid crystal panel bends, and the consistency of thickness of liquid crystal panel.
When curved surface liquid crystal panel is bending, larger stress is born at the middle part of curved surface liquid crystal panel, and the stress that curved surface liquid crystal panel end is born is relatively little, but, because the hardness of the formation material of the separator 300 at middle part is larger, and the height of the protrusion 330 at middle part is higher, and the hardness of the formation material of the separator 300 of end is less, and the height of the protrusion 330 of end is lower, thus, difference in height after the deformation of separator 300 generation of the altimetric compensation of hardness and protrusion 330 middle part and end, thus make to be consistent with the thickness of end in the middle part of curved surface liquid crystal panel.The protrusion 330 of the present embodiment is interrupted, and this protrusion 330 can be thin film transistor (TFT).Certainly, this protrusion 330 can also be continuous print, and the height of this protrusion 330 from the middle part of curved surface liquid crystal panel to end gradually and decline continuously.

In the present embodiment, from the middle part of curved surface liquid crystal panel to end, the hardness forming the material of separator 400 reduces gradually, separator 400 is fixed on first substrate 410, the inner surface of second substrate 420 is provided with groove 430, from the middle part of curved surface liquid crystal panel to end, the degree of depth of groove 430 is deepened gradually.
Such as, in the present embodiment, at the middle part of curved surface liquid crystal panel, the degree of depth of groove 430 is zero, and namely middle part does not have groove 430, and from the middle part of curved surface liquid crystal panel to end, the degree of depth of groove 430 is deepened gradually.
Particularly, the present embodiment is combined the change in depth of the firmness change of separator 400 with the groove 430 of second substrate 420 inner surface, to realize when curved surface liquid crystal panel bends, and the consistency of thickness of curved surface liquid crystal panel.
When curved surface liquid crystal panel is bending, larger stress is born at the middle part of curved surface liquid crystal panel, and the stress that end is born is relatively little, but because the hardness of the formation material of the separator 400 at middle part is comparatively large, and the degree of depth of the groove 430 at middle part is more shallow, even as the present embodiment, the middle part of second substrate 420 does not have groove 430, and on first substrate 410, the separator 400 at middle part directly contacts the inner surface of second substrate 420.And the hardness of the formation material of the separator 400 of end is less, and the degree of depth of the groove 430 of end is darker, thus, difference in height after the deformation that the separator 400 of the hardness of separator 400 and the depth compensation of groove 430 middle part and end occurs, thus make to be consistent with the thickness of end in the middle part of curved surface liquid crystal panel.The groove 430 of the present embodiment is interrupted.Certainly, this groove 430 can also be continuous print, and the height of this groove 430 from the middle part of liquid crystal panel to end gradually and decline continuously.

Below to meet with stresses the differences method of size for calculating middle panel and end: (to only have the panel of a kind of separator material and uniform density for test panel, illustrating with middle part and end-limit positional distance, can be cross stress and the extruding degree measuring left end-middle-end-right-hand member for concrete curved surface panel)
One. when materials A, B make separator have from test panel PS formed objects, highly, distribution density (or different size) time:
1) PS monomer deformation behavior is measured: the Deformation Law of PS monomer under different pressures (such as 50-500mN) (elastic deformation, plastic deformation, total deformation quantity) of different materials A, B;
2) measure test panel 1: the size of test panel separator, highly, distribution density is even, before bending after panel group is vertical, measure the gap of panel, the total deformation quantity calculating PS is Δ d.
3) measure test panel 2: measure after panel bending middle part, end panel gap and calculate total deformation quantity and be respectively Δ d1, Δ d2;
4) deformation quantity occurred when Δ d1, Δ d2 being corresponded to separator monomer different pressures, one knows middle panel, end PS monomer bears pressure can be respectively F1, F2.
5) choosing middle part materials A, at F1 pressure, total deformation quantity to occur be that total deformation quantity occurs under F2 pressure is Δ dB for Δ dA, chosen material B, Δ dA=Δ dB, and after compression as shown in figure (4) curved surface liquid crystal panel integral thickness homogeneous, be d.
Two. the separator that (gradual change) makes as materials A, B has and (different size, distribution density) during test panel phase co-altitude:
In order to expand the range of choice of materials A, B, phase co-altitude can be had but the first separator of different densities A material, the second separator of B material in curved surface middle panel, end design.(density in the panel of test sample PS is ρ survey)
6) density of the first separator of Calculating material A formation, the second separator of material B formation:
The stress F that middle panel unit area is born 1'=F 1* ρ survey(number of the separator of unit area or area)
The stress F that panel end unit area is born 2'=F 2* ρ survey(number of the separator of unit area or area)
Therefore middle panel density: ρ a=F 1'/(F (A Δ d)), (F (A Δ d)the the first separator generation Δ D-shaped formed for materials A becomes the external force be subject to)
Therefore panel end density: ρ b=F 2'/(F (B Δ d)), (F (B Δ d) for material B formed the second separator generation Δ D-shaped become the external force be subject to).
Three. when materials A, B make separator have, size different from the separator of test panel, highly, density time.
This is for expand materials A, B range of choice further.
6) the first separator that A, B material testing different size (size, highly) is formed and the Deformation Law of the second separator monomer under different pressures (such as 50-500mN) (elastic deformation, plastic deformation, total deformation quantity);
7) density of the first separator of Calculating material A formation, the second separator of material B formation:
The stress F that middle panel unit area is born 1'=F 1* ρ survey(the separator number of unit area or area)
The stress F that panel end unit area is born 2'=F 2* ρ survey(the separator number of unit area or area)
Therefore middle panel: ρ a=F 1'/(F (A Δ d ')) (F (A Δ d ')for the external force that A Δ d ' deformation is subject to occurs materials A, A Δ d ' for A material PS group vertical before and group vertical after the deformation that occurs, design object for liquid crystal panel thickness after bending even and be d, A Δ d '=PSHA-d.)
