Description

柔性液晶显示面板及其制作方法 技术领域
本发明涉及柔性显示技术领域，尤其涉及一种柔性液晶显示面板及其制作方法。
背景技术
柔性TFT-LCD(thin film transistor-liquid crystal display，即薄膜晶体管液晶显示器)具有超薄、质量轻、可弯曲、设计自由度高等特点，在可穿戴设备、手机通讯、电视、商业广告及军事应用中有这广阔的市场空间。
但因柔性设计的液晶显示屏在弯曲或折叠时，其液晶盒内基板之间的间距发生改变会产生液晶光程差，尤其是在弯曲的拐角部位变形明显，TFT-LCD显示视角变窄，导致视角对比度变差，而且，局部变形也直接加剧了基板之间的封装材料的撕裂风险。
发明内容
鉴于现有技术存在的不足，本发明提供了一种柔性液晶显示面板及其制作方法，可以改善柔性液晶显示面板的窄视角问题及封装材料的撕裂风险。
为了实现上述的目的，本发明采用了如下的技术方案：
一种柔性液晶显示面板，包括第一柔性衬底、第二柔性衬底、设于所述第一柔性衬底和所述第二柔性衬底之间的液晶与若干间隔设置的隔垫柱以及设于所述第一柔性衬底、所述第二柔性衬底之间以将所述液晶、所述隔垫柱封装于其中的封装胶，所述隔垫柱的两端分别抵接在所述第一柔性衬底和所述第二柔性衬底的内表面，所述封装胶中包裹有子隔垫物。
作为其中一种实施方式，所述子隔垫物为隔垫物颗粒，与所述封装胶的材料混合后一体形成。
或者，所述子隔垫物为柱状，两端分别抵接在所述第一柔性衬底和所述第二柔性衬底的内表面。
作为其中一种实施方式，所述第一柔性衬底朝向所述第二柔性衬底的表面设有薄膜晶体管阵列和色阻。
作为其中一种实施方式，所述隔垫柱在所述第二柔性衬底侧的径向尺寸比在所述第一柔性衬底侧更大。
作为其中一种实施方式，所述隔垫柱围成两两相邻的多个支撑单元，每个所述支撑单元包括至少三个相邻的所述隔垫柱，每两个相邻的所述支撑单元共用位于同一条直线上的多个所述隔垫柱，且每个所述支撑单元的轮廓线至少有两条边同时相对于柔性液晶显示面板的长度方向和宽度方向倾斜设置。
作为其中一种实施方式，所述支撑单元为菱形或正多边形。
本发明的另一目的在于提供一种柔性液晶显示面板的制作方法，包括：
提供第一基底和第二基底；
分别在所述第一基底和所述第二基底上制作第一柔性衬底、第二柔性衬底；
在所述第一柔性衬底上形成混有隔垫物材料的封装材料，分别形成所述第一柔性衬底外围的环形的第一部分和所述封装胶内侧的若干间隔设置的第二部分；
将所述第一柔性衬底与所述第二柔性衬底对合，并使所述封装材料固化，使所述第一部分、所述第二部分分别固化而形成封装胶、隔垫柱；
在所述第一柔性衬底与所述第二柔性衬底之间注入液晶，并封闭注入口；
剥离所述第一基底和所述第二基底。
作为其中一种实施方式，所述隔垫物材料为隔垫物颗粒。
作为其中一种实施方式，所述隔垫柱围成两两相邻的多个支撑单元，每个所述支撑单元包括至少三个相邻的所述隔垫柱，每两个相邻的所述支撑单元共用位于同一条直线上的多个所述隔垫柱，且每个所述支撑单元的轮廓线至少有两条边同时相对于柔性液晶显示面板的长度方向和宽度方向倾斜设置。
本发明的柔性液晶显示面板的封装胶与隔垫柱可以采用同一种封装材料制作，封装胶、隔垫柱既具有封装能力，又具有支撑能力，使得柔性液晶显示面板弯曲后能够保持均一的盒厚，并且边缘的封装胶不会发生撕裂风险。另外，中间的隔垫柱采用的排布方式进行排列，提升了柔性液晶显示面板整体的抗变 形能力，可以改善柔性液晶显示面板的窄视角问题。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参阅图1，本发明实施例的柔性液晶显示面板包括第一柔性衬底10、第二柔性衬底20、液晶30、若干隔垫柱40和封装胶50，其中隔垫柱40间隔设置于第一柔性衬底10和第二柔性衬底20之间，每个隔垫柱40的两端分别抵接在第一柔性衬底10和第二柔性衬底20的内表面，封装胶50设于第一柔性衬底10、第二柔性衬底20之间，将液晶30、隔垫柱40封装于其中。
封装胶50为液晶30提供了独立的封闭空间，其主要成分为环氧树脂及亚克力树脂，可以避免水汽灰尘等进入，其中，封装胶50中包裹有子隔垫物51，该子隔垫物51为隔垫物颗粒，与封装胶50的封装材料混合、固化后形成一体，使得位于柔性液晶显示面板边缘的封装胶50既具有封装特性，在被压缩时又具有隔垫物的支撑特性，能够在一定程度上保持盒厚，防止柔性液晶显示面板在弯曲过程中边缘受力而撕裂。
在一种实施方式中，第一柔性衬底10朝向第二柔性衬底20的表面设有薄膜晶体管阵列和色阻，通过将薄膜晶体管阵列和色阻制作在同一层，可以消除对合造成的组立精度偏差。
由于封装胶50中包裹有子隔垫物51，隔垫柱40表面具有封装胶，使得外围的封装胶50具有一定的承压能力，内部的隔垫柱40具有良好的粘附特性，当柔性液晶显示面板弯曲时，隔垫柱40分散于柔性液晶显示面板的显示区域， 隔垫柱40不会轻易脱离，能够保证整个柔性液晶显示面板能够保证均一的盒厚和良好的支撑性能。另外，隔垫柱40在第二柔性衬底20侧的径向尺寸比在第一柔性衬底10侧更大，即隔垫柱40在第一柔性衬底10的端部侧更细，出光面位于第一柔性衬底10侧，观看者从第一柔性衬底10很难看到隔垫柱40，因此有利于提升显示效果。
如图2所示，子隔垫物51也可以为柱状，其中部嵌设于封装胶50内，其两端也分别抵接在第一柔性衬底10和第二柔性衬底20的内表面，封装胶50内的子隔垫物51的数量在此并不做限制。
结合图3和图4所示，隔垫柱40围成两两相邻的多个支撑单元400，每个支撑单元400包括至少三个相邻的隔垫柱40，每两个相邻的支撑单元400共用位于同一条直线上的多个隔垫柱40，且每个支撑单元400的轮廓线至少有两条边同时相对于柔性液晶显示面板的长度方向和宽度方向倾斜设置。
支撑单元400为菱形或正多边形设计，如图3所示的柔性液晶显示面板中，支撑单元400为菱形，每相邻的四个隔垫柱40围成一个菱形的支撑单元400，每两个相邻的支撑单元400共用一条边上的两个隔垫柱40，众多隔垫柱40配合围成网状的图案，每个支撑单元400的轮廓线的四条边都同时相对于柔性液晶显示面板的长度方向和宽度方向倾斜设置；图4所示的柔性液晶显示面板中，支撑单元400为正六边形，每相邻的六个隔垫柱40围成一个正六边形的支撑单元400，每两个相邻的支撑单元400共用一条边上的两个隔垫柱40，众多隔垫柱40配合围成类似蜂窝状的图案，每个支撑单元400的轮廓线的四条边都同时相对于柔性液晶显示面板的长度方向和宽度方向倾斜设置。
通过这样的设计，当柔性液晶显示面板弯曲时，每个支撑单元400内，多个隔垫柱40共同配合，由于每个支撑单元400中具有多条同时相对于柔性液晶显示面板的长度方向和宽度方向倾斜设置的轮廓线，位于该倾斜的轮廓线上的隔垫柱40互相牵引施力，施力方向同时在柔性液晶显示面板的长度和宽度方向产生分力，使得每个支撑单元400内的隔垫柱40都协同配合而支撑第一柔性衬底10、第二柔性衬底20，共同抵抗柔性液晶显示面板的弯曲形变，因此，能够保证柔性液晶显示面板弯曲时的盒厚处处一致。
另外，考虑到柔性液晶显示面板弯曲时边缘部位的封装胶50需要承受较大的剪切力，在靠近外围的封装胶50的每个角落处，还可以将隔垫柱40的布置密度增大，即靠近外围的封装胶50的每个角落处，隔垫柱40的密度大于其他 区域的隔垫柱40的布置密度。
结合图5所示，本实施例的柔性液晶显示面板的制作方法主要包括：
S01、提供第一基底和第二基底，其中，第一基底和第二基底均可采用玻璃基板，以提供平整的制作表面。
S02、分别在第一基底和第二基底上制作第一柔性衬底10、第二柔性衬底20，其中，第一柔性衬底10、第二柔性衬底20的制作可以是分别在第一基底和第二基底上涂覆聚酰亚胺(Polyimide，简称PI)，并烘烤形成，因此可以做得非常薄。
S03、在第一柔性衬底10上依次制作薄膜晶体管TFT阵列和色阻，色阻的制作可以采用掩膜版刻蚀的方式形成，利用光罩曝光后刻蚀掉不需要的色阻即可。
S04、在第一柔性衬底10上形成混有隔垫物材料的封装材料，分别形成第一柔性衬底10外围的环形的第一部分和封装胶50内侧的若干间隔设置的第二部分，这里，隔垫物材料采用具有弹性的隔垫物颗粒，通过与环氧树脂及亚克力树脂封装材料充分混合后采用印刷板在第一柔性衬底10上印刷而成。其中，第一柔性衬底10边缘的印刷区域的图案为矩形的环形条，中部的区域的图案为点状的散点图案，众多散点图案围成两两相邻的菱形或正多边形图案。或者，印刷板上可以仅仅有中部的第二部分的散点图案，以对应形成隔垫柱40，而外围的环形的第一部分可以采用涂覆的方式制作而成，以对应形成封装胶50。
S05、将第一柔性衬底10与第二柔性衬底20对合，并使封装材料固化，使第一部分、第二部分分别固化而形成封装胶50、隔垫柱40。相应地，封装胶50围成矩形的封装条区域，隔垫柱40围成两两相邻的多个支撑单元400，每个支撑单元400包括至少三个相邻的隔垫柱40，每两个相邻的支撑单元400共用位于同一条直线上的多个隔垫柱40，且每个支撑单元400的轮廓线至少有两条边同时相对于柔性液晶显示面板的长度方向和宽度方向倾斜设置。
S06、在第一柔性衬底10与第二柔性衬底20之间注入液晶，并封闭注入口，形成液晶盒；
S07、剥离第一基底和第二基底，剥离时，可以采用激光照射的方式实现，剥离后，可以继续后续的切割、偏光片贴附、芯片绑定、背光模组组装等工艺。
通过上述方法制作的柔性液晶显示面板，其封装胶与隔垫柱采用同一种封 装材料制作，封装胶、隔垫柱既具有封装能力，又具有支撑能力，使得柔性液晶显示面板弯曲后能够保持均一的盒厚，并且边缘的封装胶不会发生撕裂风险。另外，中间的隔垫柱采用的排布方式进行排列，提升了柔性液晶显示面板整体的抗变形能力，可以改善柔性液晶显示面板的窄视角问题。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
