Description

可挠曲液晶面板及其制作方法 技术领域
本发明涉及显示技术领域，尤其涉及一种可挠曲液晶面板及其制作方法。
背景技术
随着可穿戴应用设备如智能眼镜、智能手表等的逐渐兴起，显示行业对可挠曲显示器件的需求也不断增加。
有机发光二极管显示器件(Organic Light Emitting Display，OLED)具有自发光，不需背光源、厚度薄、视角广、反应速度快等特点，从而具有可挠曲显示的天然优势。但是，目前OLED产业仍然具有很高的技术门槛，制程难度大、良率低、成本高、售价高，这些难点都阻碍着OLED的广泛应用。
液晶显示器(Liquid Crystal Display，LCD)是目前市场上应用最为广泛的显示产品，其生产工艺技术十分成熟，产品良率高，成本相对较低，市场接受度高。
通常，液晶显示器包括壳体、设于壳体内的液晶面板及设于壳体内的背光模组。液晶面板由一彩色滤光片基板(Color Filter，CF)、一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)以及一填充于两基板间的液晶层(Liquid Crystal Layer)等组成。CF基板和TFT基板的相对内侧设有透明电极。液晶显示器通过电场对液晶层内的液晶分子取向进行控制，改变光的偏振状态，并藉由偏光板实现光路的穿透与阻挡，达到显示的目的。
目前，大多数LCD产品，尤其是大尺寸LCD均采用柱状间隔物(Photo Spacer，PS)来控制液晶层盒厚(Cell Gap)。图1所示为一现有液晶面板在平面状态下的结构示意图，由于液晶层300内的液晶材料为液体，具有流动性，TFT基板100与CF基板200由分布于两基板之间的柱状间隔物400支撑。如图3、图4所示，所述柱状间隔物400通常采用光刻制程在显示面内的特定区域，一般在黑色矩阵(Black Matrix，BM)201上制作而成，用于维持液晶层300的厚度和稳定性。
此类柱状间隔物400无法阻挡液晶材料在整个液晶面板内的流动。虽然，如图1所示的现有液晶面板在平面状态下能够满足显示均匀性的要求， 所述液晶层300的厚度保持在设计值附近，厚度较均匀。但当原本处于平面状态的液晶面板弯曲之后，如图2所示，由于TFT基板100与CF基板200的错位、弯曲曲率不匹配等原因，造成液晶材料被挤压、流动，最终导致弯曲之后的液晶面板在不同位置出现不同的液晶层厚度变异，导致各处液晶层300的厚度不均匀，引起显示异常。
现在主流市场上常见的液晶面板分为三大类，分别是扭曲向列/超扭曲向列(TN/STN)型、平面转换(IPS)型及垂直配向(VA)型。尽管它们的调控液晶显示的原理有所不同，但是这三种类型的液晶显示面板的基本结构比较类似，其显示特性都与液晶层的厚度密切相关，液晶层厚度是否均匀对显示效果有直接影响，改变液晶层厚度会影响液晶面板的显示亮度、对比度、响应速度等。因此，非常有必要对现有液晶面板进行改进，解决因弯曲而导致的液晶层厚度不均匀的问题，使得液晶面板能够应用于可挠曲显示。
发明内容

所述间隔挡墙5包括数条相互平行的沿横向延伸的横部51、及数条相互平行的沿纵向延伸的纵部53，所述横部51与纵部53相互交错，分隔出多个子像素。所述液晶层9填充于所述横部51与纵部53相互交错构成的封闭区域内。
所述间隔挡墙5通过黄光制程制作；所述密封胶7通过转印法涂覆；所述液晶层9通过喷射方式注入液晶。
所述第一可挠曲基板1与第二可挠曲基板3均透明且具有挠曲性。具体的，所述第一可挠曲基板1与第二可挠曲基板3均为塑料基板，优选的，所述第一可挠曲基板1与第二可挠曲基板3均为聚酰亚胺(PI)基板或聚对苯二甲酸乙二醇酯(PET)基板。
值得一提的是，所述密封胶7为UV固化与热固化复合型固化胶，通过UV固化与热固化的复合方式进行固化。所述密封胶7的组分为预聚物树脂、粘度调节剂、光引发剂、热硬化剂及填料。
具体的，所述预聚物树脂占总重量比重的10％-60％，其由一类或多类含可聚合基团(如：丙烯酸酯基、甲基丙烯酸酯基、环氧基)的预聚物组成，其中至少一类预聚物同时含有UV固化的丙烯酸酯基与热固化的环氧基，其可以为但不限于以下结构：
Figure PCTCN2015072501-appb-000001
n为0-10的整数。
所述粘度调节剂占总重量比重的5％-30％，其为分子量较小、粘度较低的含可聚合基团的活性单体，可以为但不限于以下结构：
Figure PCTCN2015072501-appb-000002
所述光引发剂占总重量比重的0.05％-1％，采用汽巴艳佳固(CIBA IRGACURE)系列商品化光引发剂，例如CIBA IRGACURE651，其结构如下：
Figure PCTCN2015072501-appb-000003
所述热硬化剂占总重量比重的10％-40％，采用酸酐系列或胺类系列化合物，可以为但不限于以下结构：
Figure PCTCN2015072501-appb-000004
所述填料占总重量比重的5％-20％，其为无机颗粒状物质，可选用二氧化硅、氧化铝、氧化锌、氧化钛、氧化镁、硫酸钙、氮化铝、或氮化硅等。
进一步的，如图8所示，所述第一可挠曲基板1内侧还设有栅极线101、数据线102、TFT103、及ITO像素电极104，相当于现有液晶面板中的TFT基板。
如图9所示，所述第二可挠曲基板3内侧还设有ITO公共电极304，相当于现有液晶面板中的CF基板。
由于液晶层9填充于所述间隔挡墙5的横部51与纵部53相互交错构成的封闭区域内，并在所述间隔挡墙5靠近第一可挠曲基板1的一侧涂覆密封胶7将第一、与第二可挠曲基板1、3粘结在一起，所述间隔挡墙5能够阻挡液晶在面板内的流动，稳定支撑第一、与第二可挠曲基板1、3之间的液晶层盒厚，使该可挠曲液晶面板在弯曲之后仍可保持良好的液晶层厚 度均匀性，保证可挠曲显示的品质。另外，传统的液晶面板一般通过胶框来实现上、下基板的粘合，而本发明的可挠曲液晶面板与传统液晶面板不同，不设置胶框，而是采用所述密封胶7来实现第一可挠曲基板1与第二可挠曲基板3的粘合，若不使用密封胶7则无法将第一可挠曲基板1与第二可挠曲基板3粘结在一起。值得一提的是，所述密封胶7为UV固化与热固化复合型固化胶，在其组分中，至少一类预聚物同时含有UV固化的丙烯酸酯基与热固化的环氧基，该密封胶7经UV固化与热固化的复合方式进行固化后，能够将第一可挠曲基板1与第二可挠曲基板3紧密、牢固的粘结在一起，并且所述密封胶7涂覆于所述间隔挡墙5靠近第一可挠曲基板1的一侧，直接与所述间隔挡墙5接着，既易于制作，又能与间隔挡墙5共同作用，阻挡液晶在面板内的流动。
