Description

一种用于曲面显示的液晶显示面板及液晶显示装置
本申请要求于2017年10月26日提交中国专利局、申请号为201711020915.9、发明名称为“一种用于曲面显示的液晶显示面板及液晶显示装置”的中国专利申请的优先权，上述专利的全部内容通过引用结合在本申请中。
技术领域
本发明涉及显示领域，特别涉及一种用于曲面显示的液晶显示面板及液晶显示装置。
背景技术
液晶显示器的显示质量和整体性能在很大程度上受材料、器件结构以及工艺过程的影响。目前，液晶显示器的显示面板是在阵列基板和彩膜基板之间注入液晶材料并且对盒形成的。通过对阵列基板和彩膜基板上的电极施加电压形成电场来控制液晶盒中液晶的取向，利用液晶分子的光学各向异性、双折射性等光学特性控制穿过液晶盒的光通量，从而获得所需图形。由于阵列基板和彩膜基板所形成的液晶盒的厚度直接影响穿过液晶盒的光通量，因此控制及维持液晶盒的厚度对提高液晶显示器显示的均匀性、优化显示性能有着极为重要的作用。
为了控制及维持显示面板的液晶盒厚度的一致性，现有技术中有一种方法是在彩膜基板上形成高度一定的柱状隔垫物来实现。例如，如图1中所示，在形成了黑矩阵201’、彩色像素层202’、公共电极层以及液晶取向层的彩膜基板200’上形成柱状隔垫物(PS，Post Spacer)层，利用掩模板将PS层通过光刻工艺在彩膜基板上形成柱状隔垫物102’，利用位于彩膜基板200’和阵列基板100’之间的柱状隔垫物102’以及封框胶101’来控制及维持液晶盒的厚度；由于柱状隔垫物102’的位置、高度、形貌可通过光刻工艺精确控制，因此使用柱状隔垫物的液晶显示器在显示性能上有极大的 提高。
然而，在一些应用场合，例如在曲面显示情形下，当显示面板在受到挤压时，在外界压力作用下柱状隔垫物容易因变形而产生侧向滑动，造成液晶盒的厚度发生变化，从而导致液晶显示器显示不均，出现漏光等不良现象，影响液晶显示器的显示性能；并且会对基板表面的液晶取向层造成损伤，导致显示的异常。

具体地，所述倒梯形沟槽23形成于所述色阻层21上，且位于两种色阻交界区域。
可以理解的是，在所述实施例中，可以理解的是，所述倒梯形沟槽23的所述为倒梯形的纵向截面所在的平面，与所述曲面液晶显示屏弯曲时其一条栅极线所形成平面重合或平行。
所述柱状间隙子11的顶面与所述梯形沟槽23的底面在所述纵向截面方向上尺寸相同。而在与所述纵向截面垂直的另一个方向上，所述倒梯形沟槽 23以及所述柱状间隙子11的尺寸不作限制。如图4所示，在两种色阻交界的区域设置倒梯形沟槽23，其在沿栅极线(图中Gate线)的方向的纵向截面为倒梯形，其在另一方向上，即图中Data线(数据线)方向上可以呈线条型；其中黑色区域为柱状间隙子11的定位区域，从中，可以看出该柱状间隙子11可以点状结构(如图4左侧示出的间隙子形状)，也可以是长条形结构(如图4右侧示出的间隙子形状)。可以理解的是，图4示中示出了多种结构的间隙子，在实际运用中，常采用其中一种间隙子形状。同时，利用该结构中，将柱状间隙子11伸入倒梯形沟槽23中，可以保证柱状间隙子11在D1方向上的限位，可以防止上基板与下基板在D1方向上的滑移错位，从而提高显示器按D1弯曲时，显示质量的稳定性。
另外，在所述上基板1下表面与所述柱状间隙子11之间进一步设置有黑矩阵层10。可以理解的是，在一些例子中，黑色矩阵层10与柱状间隙子11可以分别采用单独的制程制备而成；在其他的一些例子中，也可以采用BPS(丙烯酸)等材料通过一次曝光显影制得所述黑色矩阵层10与柱状间隙子11，即所述黑色矩阵层10与柱状间隙子11一体成型。
如图5所示，示出了本发明提供的一种液晶显示面板的另一个实施例的结构示意图。从中可以看出，其与图3示出的结构的不同之处在于，在所述色阻层21上进一步形成有保护层22，可以理解的是，所述保护层22可以采用如无机SiNx，有机PFA等材料，其可以是一层结构，也可以是多层结构。所述倒梯形沟槽23贯穿所述保护层22与所述色阻层21(即将所述保护层22以及所述色阻层21挖开形成沟槽)，且位于两种色阻交界区域(例如，设置于数据线位置上)。其他结构与图3示出的类似，不再赘述。
如图6所示，示出了本发明提供的一种液晶显示面板的又一个实施例的结构示意图。一并结合图7所示，从中可以看出，其与图3示出的结构的不同之处在于，在所述色阻层21上进一步形成有保护层22，所述色阻层21采用连接设计，所述倒梯形沟槽23形成于所述保护层22上(即将所述保护层22挖开形成沟槽)。其他结构与图3示出的类似，不再赘述。
相应地，本发明还提供了一种液晶显示装置，其包括前述图2至图7中示出的液晶显示面板。
实施本发明实施例，具有如下有益效果：
实施本发明提供的液晶显示面板，利用其上基板上向下延伸出纵向截面为倒梯形的间隙子，同时在上基板的色阻层或/及保护层上设置倒梯形沟槽，所述间隙子与所述倒梯形沟槽进行配合，从而使在液晶显示面板的栅极线方向上，所述倒梯形沟槽对所述倒梯形的间隙子实现卡扣，可以防止间隙子的移动，可以防止上基板与下基板在栅极线方向方向上的滑移错位，保证了显示质量的稳定性；同时，本发明仅在栅极线方向对所述间隙子和倒梯形沟槽进行尺寸的限制，在另一方向不作可以限制，降低上基板与下基板对位的难度。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个......”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
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。
