Description

反射式柔性液晶显示器
技术领域
本发明涉及显示技术领域，尤其涉及一种反射式柔性液晶显示器。
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。
就目前主流市场上的LCD而言，可分为三大类，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，尽管它们各自调控液晶显示的原理有所不同，但是这三种类型的LCD的基本结构都比较类似，可以用图1所示结构来表示，均至少包括液晶显示面板100、及背光组件200，液晶面板本身不发光，需要由背光组件提供光源。进一步地，液晶显示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)所构成。CF基板远离液晶层的一侧贴附一偏光片，TFT基板远离液晶层的一侧也贴附一偏光片。LCD通过电场对液晶分子的取向进行控制，改变光的偏振状态，并藉由偏光片实现光路的穿透与阻挡，达到显示的目的。
如上所述，由于液晶显示面板由两片基板及夹于其间的液晶层组成，需要借助背光组件提供光源进行显示，LCD属于非自发光的液态显示器件。在LCD向柔性显示应用方向发展的过程中，仅仅简单将液晶显示面板部分做成柔性可弯曲的还远远不够实际应用，还需要有柔性的背光组件进行搭配才能使用，但是背光组件包括光源、多层膜片以及导光板等多个部件，所以要开发柔性LCD产品需要采用其他方法与途径，远非简单地将液晶显示面板做成柔性那么容易。

具体实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图2至图8，本发明提供一种反射式柔性液晶显示器。如图2所示，该反射式柔性液晶显示器包括：柔性上基板1、与所述柔性上基板1相对设置的柔性下基板3、填充于所述柔性上基板1与柔性下基板3之间的液晶层5、设于所述柔性上基板1上表面的圆偏光片、及设于所述圆偏光片上表面的柔性导光板9；所述柔性上基板1与柔性导光板9均透明，所述柔性下基板3具有反射层37。
进一步地，所述柔性导光板9的至少一侧设有侧光源2。图2所示的实施例中，所述柔性导光板9的一侧设有侧光源2。
所述液晶层5为垂直配向型液晶层。在不施加电压的情况下，所述液晶层5中的液晶分子相对于水平方向垂直排列，光线经过该液晶层5不产生相位延迟；施加电压后，所述液晶层5中的液晶分子相对于水平方向偏转特定的角度，光线经过该液晶层5产生相位延迟，且最大相位延迟量为可见光波长的1/4，确切地说，所述液晶层5的盒厚与施加电压前后液晶折射率的差值的乘积等于可见光波长的1/4，即100-200nm之间。
结合图3、图4，所述圆偏光片包括线偏光片7和贴附于所述偏光片7的下表面的一λ/4膜71。本发明选用由正晶体构成的λ/4膜，其快轴与光轴方向垂直，且与线偏光片7的吸收轴成45度夹角，该λ/4膜起到偏光作用。
所述线偏光片7、λ/4膜71、液晶层5、与反射层37共同作用来对光路进行控制。如图3所示，在不施加电压的情况下，入射光线依次经所述线偏光片7、λ/4膜71偏光后，穿过液晶层5并不产生相位延迟，照射到反射层37；反射层37对光线进行反射，反射光线穿过液晶层5并不产生相位延迟，再经λ/4膜71偏光，最终使得反射光线平行于所述线偏光片7的吸收轴，被线偏光片7吸收掉，不能射出，从而不进行显示。如图4所示，施加电压后，入射光线依次经所述线偏光片7、λ/4膜71偏光后，经过液晶层5产生相位延迟，照射到反射层37；反射层37对光线进行反射，反射光线经过液晶层5再次产生相位延迟，再经λ/4膜71偏光，最终使得反射光线垂直于所述线偏光片7的吸收轴，能够穿过线偏光片7射出，从而进行显示。
如图5、图6所示，在外部光强较强的环境中，如太阳或日光灯的照射下，本发明的反射式柔性液晶显示器使用外部光源如太阳或日光灯进行工作，不需要启动侧光源2。在不施加电压的情况下，由外部光源发出的入射光经所述线偏光片7、λ/4膜71、液晶层5、与反射层37的共同作用，最终反射光线平行于所述线偏光片7的吸收轴，被线偏光片7吸收掉，不能射出，从而不进行显示；在施加电压的情况下，由外部光源发出的入射光经所述线偏光片7、λ/4膜71、液晶层5、与反射层37的共同作用，最终反射光线垂直于所述线偏光片7的吸收轴，能够穿过线偏光片7射出，从而进行显示。
如图7、图8所示，在外部光强较弱的环境中，如没有太阳或日光灯的照射，本发明的反射式柔性液晶显示器则启动所述侧光源2进行工作，并可以根据外部环境的光强实际情况对所述侧光源2进行亮度调节，使该液晶显示器仍能正常使用。在不施加电压的情况下，由侧光源2发出的光经导光板9反射和扩散后成为入射光，再经所述线偏光片7、λ/4膜71、液晶层5、与反射层37的共同作用，最终反射光线平行于所述线偏光片7的吸收轴，被线偏光片7吸收掉，不能射出，从而不进行显示；在施加电压的情况下，由侧光源2发出的光经导光板9反射和扩散后成为入射光，再经所述线偏光片7、λ/4膜71、液晶层5、与反射层37的共同作用，最终反射光线垂直于所述线偏光片7的吸收轴，能够穿过线偏光片7射出，从而进行显示。
上述反射式柔性液晶显示器由于设置了柔性的上、下基板1、3及导光板9，能够方便的应用于柔性显示；由于在柔性上基板1的上表面设置了唯一的圆偏光片，及在柔性下基板3上设置了反射层37来控制光路，实现了反射式显示，相比于现有的使用两片偏光片的液晶显示器，结构更加简单。
具体的，所述柔性导光板9由透明柔性基材制成，其材质可选择但不限于以下材料：聚甲基丙烯酸甲酯(PMMA)、聚碳酸酯(PC)、聚乙烯(PE)、聚丙烯(PP)、聚对苯二甲酸乙二酯(PET)、或聚酰亚胺(PI)。如图9、图10所示，所述柔性导光板9的上表面分布有多个散射网点91，能够增加所述柔性导光板9对光线的扩散效果。所述柔性导光板9相对所述侧光源2的一侧还设有反光板4，能够提高光线的利用率。
所述侧光源2优选为LED灯管。
如图11、图12所示，所述柔性上基板1包括一透明柔性基底11、设于所述透明柔性基底11下表面的平坦层12、设于所述透明柔性基底11与平坦层12之间的彩色滤光层13、设于所述平坦层12下表面的透明导电电极14、及设于所述透明导电电极14下表面的黑色矩阵挡墙15。该柔性上基板1所起的作用相当于传统液晶显示面板中的CF基板。进一步地，所述透明柔性基底11的材质可选择但不限于以下材料：玻璃、PMMA、PC、PE、PP、PET、或PI。

所述反射层37为金属层，位于所述层间绝缘层36上。
所述栅极32、半导体层34、与源/漏极35构成TFT。所述反射层37接触所述源/漏极35，兼做电极。
