Description

曲面液晶显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种曲面液晶显示面板。
背景技术
液晶显示器(Liquid Crystal Display，LCD)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，其中液晶面板由一彩色滤光片基板(Color Filter Substrate，CF Substrate)、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分子的取向进行控制，改变光的偏振状态，并藉由偏光板实现光路的穿透与阻挡，实现显示的目的。随着显示技术的发展，人们对消费性电子产品的要求已经不单单局限于功能性，同时也更转向于设计性、艺术性以及具有良好的视觉体验性方面，如此前应运而生的曲面液晶显示器，不仅设计新颖，同时视觉体验效果更佳。
曲面液晶面板是曲面液晶显示器的核心组成部分。当前曲面液晶面板的制作方法为：先将制作完成的CF基板与TFT基板在平面状态下贴合，形成一平板状的液晶面板，再将该平板状的液晶面板在外力作用下，使原本呈平板状态的液晶面板发生弯曲，并依照液晶面板的设计尺寸以及观赏距离来决定弯曲的程度(曲率半径)。
在传统的垂直配向(Vertical Alignment，VA)型显示器中，为了解决视角的色偏问题，一般会将子像素(Sub-pixel)分为若干个分区(Domain)。子像素中的像素单元通常呈鱼骨状结构，分区之间的交界区域一般被称为ITO(Indium Tin Oxide，氧化铟锡)Trunk(躯干)区。
如图1所示，在制作曲面显示器的过程中，形成曲面后，由于上下基板以面板中心为基准，在水平方向上会往左右两边逐渐产生相对移位(shift)，CF基板100相对于TFT基板200会形成分别向左右两边滑动的应力；因此会使得薄膜晶体管阵列基板200中的ITO Trunk发生相对位移，像素单元中电场会发生变化，造成曲面显示器中位于ITO Trunk附近的位置会变暗。
如图2所示，CF基板100相对于TFT基板200向右移位，ITO Trunk210右侧，即方框区域所示区域的液晶300则会出现倒向错乱而无法还原的情 况，从而形成暗纹。
由于上下基板的相对移动量从中间往两边是逐渐增大，液晶面板的中心区无相对移动量，液晶面板的中心区上的子像素内的ITO Trunk不偏移，而液晶面板左右两侧区域上的子像素内的ITO Trunk发生偏移，形成暗纹区，这样就会造成中心区和暗纹区域有明显的亮度差异，使得面板出现亮度分布不均匀(Mura)的现象。
故，有必要提出一种新的技术方案，以解决上述技术问题。

具体实施方式
为更进一步阐述本发明所采取的技术手段极其效果，以下结合本发明的优选实施例极其附图进行详细描述。
请参阅图3-图11，本发明提供一种曲面液晶显示面板，包括：TFT基板1、与TFT基板1对应设置的CF基板2、及设于TFT基板1与CF基板2之间的液晶层5。
所述TFT基板1包括第一基板11、设于所述第一基板11上的第一黑色矩阵、设于所述第一基板11与第一黑色矩阵上的数个遮光金属框16、设于所述第一基板11上覆盖所述数个遮光金属框16的绝缘层17、设于所述绝缘层17上的数条数据线13、数条栅极扫描线、及像素电极层。
所述数条数据线13、以及数条栅极扫描线围出数个子像素区域，所述数个遮光金属框16分别位于所述数个子像素区域内；所述像素电极层对应每一子像素区域具有一像素电极14，所述像素电极14具有多域结构，所述多域结构包括主干部分141和分支部分；所述第一黑色矩阵对应每一子像素区域具有一黑色遮光条12。
平面状态下，所述黑色遮光条12位于所述像素电极14的主干部分141的下方，所述黑色遮光条12的宽度小于或等于所述主干部分141的宽度；
曲面状态下，曲面液晶显示面板的两侧区域内，所述CF基板2相对于TFT基板1发生相对偏移，于所述像素电极14的主干部分141一侧上方产生暗纹区域91，所述黑色遮光条12遮住所述暗纹区域91；曲面液晶显示面板的中间区域内，所述黑色遮光条12遮住与所述暗纹区域91宽度相同的正常区域，从而使得曲面液晶显示面板的亮度均匀。
所述CF基板2包括第二基板21、设于第二基板21上的色阻层22。
具体地，所述遮光金属框16包括位于所述主干部分141下方的第一遮光部161、及位于所述子像素区域周边的第二遮光部162；所述第一遮光部161的宽度小于所述主干部分141的宽度。请参阅图3至图4，为本发明曲面液晶显示面板的第一实施例，所述黑色遮光条12的宽度等于所述主干部分141的宽度。
平面状态下，所述黑色遮光条12位于所述主干部分141的正下方，所述黑色遮光条12的两端分别与主干部分141的两端对齐；曲面状态下，所述黑色遮光条12遮住所述暗纹区域91。
在曲面液晶显示面板制作过程中，在面板曲率固定后，不同区域的上下基板相对偏移量可根据经验数据和模拟得出，这样就可以推断出各区域内预产生暗纹区域91的大小，一般情况下，暗纹区域91的宽度S略小于相对偏移量的大小；且面板曲率固定后，不同区域的上下基板相对偏移方向也可以确定，即暗纹区域91的方向可以确定，因此，第一黑色矩阵可以根据上下基板相对偏移方向采取单边补偿，从而使得开口率有所提高。
请参阅图5至图8，为本发明曲面液晶显示面板的第二实施例，所述黑色遮光条12的宽度小于所述主干部分141的宽度。
根据曲面状态下CF基板2相对于TFT基板1的相对偏移方向的不同，将所述曲面液晶显示面板划分为左、右两部分；
平面状态下，位于左侧的液晶显示面板内，在竖直方向上所述黑色遮光条12的左端与第一遮光部161的左端对齐，所述黑色遮光条12的右端与主干部分141的右端对齐；位于右侧的液晶显示面板内，在竖直方向上所述黑色遮光条12的右端与第一遮光部161的右端对齐，所述黑色遮光条12的左端与主干部分141的左端对齐；
曲面状态下，位于左侧的液晶显示面板内，在竖直方向上所述黑色遮光条12的左侧遮挡所述暗纹区域91，位于右侧的液晶显示面板内，在竖直方向上所述黑色遮光条12的右侧遮挡所述暗纹区域91。
所述第一基板11上设有沟槽111，所述第一黑色矩阵位于所述沟槽111内。
另外，本发明适用于BOA(BM on Array)型的液晶面板、和非BOA型的，即本发明的曲面液晶显示面板内，还包括用于防止子像素区域边缘漏光的第二黑色矩阵23，该第二黑色矩阵23可以位于CF基板2上，也可以位于TFT基板1上。
请参阅图9至图10，为本发明曲面液晶显示面板的第三实施例，所述TFT基板还包括设于第一基板11上的第二黑色矩阵23，所述第二黑色矩阵23与所述第一黑色矩阵同一制程形成，所述第二黑色矩阵23与所述第一黑色矩阵均设于所述第一基板11表面。
请参阅图11至图12，为本发明曲面液晶显示面板的第四实施例，与第三实施例的不同之处在于，所述第一基板11上设有沟槽111，所述第一黑色矩阵、及所述第二黑色矩阵23位于所述沟槽111内，其余部分均与第三实施例相，此处不再赘述。
综上所述，本发明的曲面液晶显示面板，TFT基板上对应像素电极的主干部分设有黑色矩阵，以将曲面液晶显示面板的两侧区域内的子像素中预产生暗纹的部分、以及曲面液晶显示面板的中间区域内的子像素中相应宽度的部分被遮住，在损失掉一部分开口率的情况下，使得曲面液晶显示面板上各区域的亮度均匀，避免了曲面液晶显示面板中间区域与两侧区域间的亮度差异。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
