Abstract

提供了一种曲面液晶面板及其制备方法，包括：阵列基板（10）设置薄膜晶体管（11）；彩膜基板（20）设置主间隔子（23）与副间隔子（24），主间隔子（23）与薄膜晶体管（11）相对设置，副间隔子（24）与主间隔子（23）的段差从面板中间向边界递减；两基板（10，11）之间填充液晶并密封。通过设计不等高度的主副间隔子段差，防止曲面面板在不同区域的盒厚不均而导致的光学品味下降。

Description

液晶面板及其制备方法 技术领域
本发明涉及液晶显示领域，尤其涉及一种曲面液晶面板及其制备方法。
 背景技术
在显示面板（Liquid Crystal Display，TFT-LCD）的制程中，通常在阵列（Array）基板10与彩膜（Color Filter，CF）基板20之间制作一层间隔子（Photo Spacer，PS），用于支撑阵列基板10与彩膜基板20之间的具有空隙（Cell Gap）。在制程中应保证空隙在各个地方都均匀等高。
如图1A中，间隔子有主（Main）间隔子21和副（Sub）间隔子22之分。主间隔子21连接于薄膜晶体管（Thin Film Transistor，TFT）11上，而副间隔子一端悬空。这种情况下，主间隔子21和副间隔子22之间就有一个高度差即间隔子段差30。且在通常情况下，只有主间隔子21工作。如图1B中，在面板受挤压时，副间隔子22才会起作用。
在制备曲面电视时，其原理同图1B，由于曲面电视具有一定的弧度，向内凹或向外凸，阵列基板10与彩膜基板20之间会产生相对滑动的力，面板左右两边会以面板中心为基点分别产生左右滑动的应力，同时在面板中间上下基板10与20相互挤压的应力会大于左右两边，由于主副间隔子采取等段差30设计（即面板各处的主间隔子21与副间隔子22的高度差都相同），故中间部分受应力挤压更严重，造成曲面面板中间的空隙会小于两边，导致中间和两边的穿透率和响应时间不同，因而造成曲面液晶面板会出现光学品味下降。
因此，如何设计一种适合曲面显示面板的间隔子，使其厚度均匀、品质稳定，成为液晶显示设备的一大研发方向。
 技术问题
有鉴于此，本发明提供一种曲面液晶面板及其制备方法，旨在通过设计不同区域的不等高间隔子差，使曲面液晶面板内厚度一致，不易出现由面板内盒厚不均导致的显示不均（mura）。
 技术解决方案

图2是本发明一实施例中曲面液晶面板在未挤压前的剖面示意图。
图3是图2进行内凹挤压后的曲面液晶面板的剖面示意图。

图5是本发明一实施例制备曲面液晶面板的流程示意图。
 本发明的最佳实施方式
请参照附图中的图式，其中相同的组件符号代表相同的组件。以下的说明是基于所例示的本发明具体实施例，其不应被视为限制本发明未在此详述的其它具体实施例。
实施例一
请参阅图2，所示为曲面液晶面板未挤压前的剖面示意图。
所述曲面液晶面板由阵列基板10与彩膜基板20对盒而成，其中，所述阵列基板10上设置有多个薄膜晶体管11。彩膜基板20上设置有多个主间隔子23与多个副间隔子24。所述阵列基板10与所述彩膜基板20之间的显示区域内填充液晶（未标示），并通过框胶（未标示）进行密封。
具体而言，所述主间隔子23与所述薄膜晶体管11相对应。可以理解的是：所述相对应通常是指接触但不固定连接。即，主间隔子23与薄膜晶体管11之间可以互相支撑，但在受到外力的情况下，如挤压，可能存在轻微的相对位移。
副间隔子24与主间隔子23成对设置，且相邻主间隔子23与副间隔子24的段差从液晶面板中间向边界递增。
可以理解的是：所述段差产生的方式包括：
一、所述副间隔子24的长度变化为从液晶面板中间向边界变短，但主间隔子23长度相同；
二、所述副间隔子24与主间隔子23的长度变化皆为从液晶面板中间向边界变短，但副间隔子24比主间隔子23的变化幅度更大。
上述段差的变化主要取决于曲面液晶面板的预装弧度及各主间隔子23与副间隔子24在曲面液晶面板所对应的具体位置。
主间隔子23与副间隔子24的形状通常包括柱状与球状。本发明以柱状为例进行阐述。比如，在一种设计中主间隔子23与副间隔子24的截面呈梯形，即所述主副间隔子23、24的形状为圆锥型或梯型。在其他设计中，亦不排除主间隔子23与副间隔子24呈球状，可以理解的是，高度差是指其直径差，且变化规律与本设计中的段差的构思相同。
实施例二
请参阅图2所示为曲面液晶面板未挤压前的剖面示意图。
所述曲面液晶面板由阵列基板10与彩膜基板20对盒而成，其中，所述阵列基板10上设置有多个薄膜晶体管11。彩膜基板20上设置有多个主间隔子23与多个副间隔子24。所述阵列基板10与所述彩膜基板20之间的显示区域内填充液晶，并通过框胶进行密封。
具体而言，所述主间隔子23与所述薄膜晶体管11相对应。可以理解的是：所述相对应通常是指接触但不固定连接。即，主间隔子23与薄膜晶体管11之间可以互相支撑，但在收到外力的情况下，如挤压，可能存在轻微的相对位移。
副间隔子24与主间隔子23成对设置，且所述副间隔子24的长度随在所述曲面液晶面板的位置而变化，如从液晶面板中间向边界变短，并取决于所述曲面液晶面板的预装弧度。
此外，与所述副间隔子24所对应的主间隔子23的长度即可以是相同的，亦可以随副间隔子23变化，但变化幅度略小，即：所述主副间隔子23、24的长度会使其段差从液晶面板中间向边界变短。
上述变化主要取决于所述曲面液晶面板的预装弧度、及所述各主间隔子23与副间隔子24在曲面液晶面板所对应的具体位置。
主间隔子23与副间隔子24的形状通常包括柱状与球状。本发明以柱状状为例进行阐述。比如，在一种设计中主间隔子23与副间隔子24的截面呈梯形，即所述主、副间隔子23、24的形状为圆锥型或梯型。
在其他设计中，亦不排除主间隔子23与副间隔子24呈球状，可以理解的是，高度差是指其直径差，且变化规律与本设计中的段差的构思相同。
实施例三
请参阅图3所示的内凹型曲面与图4所示的外凸型曲面。所示为图2的液晶面板经挤压后形成。
如图3所示，阵列基板10与彩膜基板20向阵列基板10一侧弯曲凹陷，使主间隔子23与薄膜晶体管11相对应，副间隔子24与阵列基板10的板面相对应。
如图4所示，阵列基板10与彩膜基板20向彩膜基板20一侧弯曲凹陷，使主间隔子23与薄膜晶体管11相对应，副间隔子24与阵列基板10的板面相对应。
即，曲面液晶显示面板的盒厚保持一致，不会因厚度不均而引起光学品质的下降。
实施例四
请参阅图5，本发明一实施例制备曲面液晶面板的流程示意图。所述曲面液晶面板的制备方法，包括步骤：
在步骤S501中，制备阵列基板，所述阵列基板上设置有多个薄膜晶体管。
在步骤S502中，制备彩膜基板，所述彩膜基板上设置有多个主间隔子与副间隔子，所述副间隔子与主间隔子的段差从液晶面板中间向边界递减。
可以理解的是：所述多个主间隔子的与副间隔子成对设置。所述副间隔子的长度变化为从液晶面板中间向边界变短，并取决于曲面液晶面板的预装弧度。各主间隔子的长度相同或变化幅度略小于所述副间隔子。
此外，所述主间隔子与副间隔子既可以是柱状、也可以是球形。可以理解的是，所述段差是主副隔离子的高度差，即当主副隔离子为柱状时，为高度差；当主副间隔子为球形时，为直径差。
在步骤S503中，注入液晶。
在步骤S504中，贴合所述阵列基板与所述彩膜基板，使所述主间隔子与所述薄膜晶体管位置相对应。
可以理解的是：所述相对应是指不固定连接。即，主间隔子23与薄膜晶体管11之间可以互相支撑，但在收到外力的情况下，如挤压，可能存在轻微的相对位移。
此外，在贴合过程中，应注意使所述液晶刚好填满所述阵列基板与所述彩膜基板的空隙。
在步骤S505中，将所述液晶盒弯折至预装弧度，形成曲面液晶面板。
可以理解的是：所述弯折，包括图3所示的内凹型曲面及图4所示的外凸型曲面。
本发明是根据曲面显示器的特点（在曲面显示器的中间部分，上下基板相互挤压的应力大于左右两边），采取设计不等段差的主副间隔子，内凹曲面显示器时，让所述段差在中间区域大于两边，这样，在中间区域由于段差较大，在变成曲面显示器时，其耐压性较好，而边缘地区由于段差较小使得耐压性稍差，而加之中间受压力较大，故可以使得显示器的整个区域（cell gap）盒厚保持一致（具体段差值由显示器预装弧度确定）。同理对于外凸型曲面显示器也可以通过相同方法保持盒厚一致。综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通测试人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
