Description

一种曲面液晶显示面板及显示装置 技术领域
本发明涉及显示技术领域，特别是涉及一种曲面液晶显示面板及显示装置。
 背景技术
曲面屏幕一般可通过柔性OLED面板及LCD面板弯曲实现，“曲面”不仅是对电视外观形态的颠覆，更是对观看舒适度的显著改善，合适的曲率提供了更宽广的视野和更为强烈的临场感，人的眼球是凸起有弧度的，曲面屏幕的弧度可以保证眼睛的距离均等，从而可以提高观看效果。
 技术问题
曲面液晶显示面板是由平面的显示面板弯曲得到，如图1所示，曲面液晶显示面板包括第一基板10和第二基板20，第一基板10和第二基板之间还设置有间隙子21，其中，曲率越大的位置（面板中间区域）受到的力会越大，间隙子21受力越大，压缩量越大，对应的液晶盒厚度（Cell Gap）d会越小。由于穿透率与间隙成正比，因此当液晶盒厚度减小时，中间区域的穿透率（Tr）会比边缘低，当中间区域与边缘区域的穿透率不同，对应RGB的Tr也会不同，从而导致中间区域与边缘区域的画面出现差异，由于弯曲的原因，面内的电场方向发生变化，对应液晶分子导向也会发生变化，从而出现色偏，降低了显示效果。
因此，有必要提供一种曲面液晶显示面板及显示装置，以解决现有技术所存在的问题。
 技术解决方案
本发明的目的在于提供一种曲面液晶显示面板及显示装置，能够提高穿透率以及降低色偏，进而提高显示效果。
为解决上述技术问题，本发明提供一种曲面液晶显示面板，其包括中间区域和边缘区域，其截面结构包括：
第一基板；
第二基板，与所述第一基板相对设置；
液晶层，设于所述第一基板和所述第二基板之间；
补偿层，设于位于中间区域的第二基板中远离所述液晶层的一侧；中间厚度与边缘厚度之间的差值小于等于预设值，其中所述中间厚度为位于所述中间区域的曲面液晶显示面板的厚度；所述边缘厚度为位于所述边缘区域的曲面液晶显示面板的厚度；
多个补偿液晶分子，填充于所述第二基板与所述补偿层之间。
本发明还提供一种显示装置，其包括上述任意一种曲面液晶显示面板。
 有益效果
本发明的曲面液晶显示面板及显示装置，通过在位于中间区域的第二基板中远离所述液晶层的一侧设置补偿层；所述第二基板与所述补偿层之间填充个多个补偿液晶分子，从而使得显示面板的厚度均匀，提高了穿透率，此外增加了光线的出射角度，降低了色偏，进而提高了显示效果。
 附图说明
图1为现有的曲面液晶显示面板的结构示意图；
图2为本发明的曲面液晶显示面板的结构示意图；
图3为本发明的曲面液晶显示面板的光路图。
 本发明的实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图2至3，图2为本发明的曲面液晶显示面板的结构示意图。
如图2所示，在一实施方式中，本发明的曲面液晶显示面板包括中间区域101和边缘区域102；其中边缘区域102设于中间区域101的两侧。曲面液晶显示面板的截面结构包括第一基板10、第二基板20、液晶层（图中未示出）以及补偿层40。
第二基板20与所述第一基板10相对设置。其中所述第二基板20靠近显示侧，也即所述第二基板20靠近观察者。
液晶层设于所述第一基板10和所述第二基板20之间。结合图3，所述液晶层中可填充有偏转液晶分子11。其中所述中间间隙为位于所述中间区域101的第一基板10和第二基板20之间的间隙；所述边缘间隙为位于所述边缘区域102的第一基板10和第二基板20之间的间隙；中间间隙小于边缘间隙，比如中间间隙中的最小值为d1，边缘间隙中的最大值为d2。也即未增加补偿层之前，边缘厚度大于中间厚度。
补偿层40设于位于中间区域101的第二基板20中远离所述液晶层的一侧；也即补偿层40位于第二基板20的外侧。其中补偿层40的材料为绝缘材料，其材料可以为SiNx、SiO2中的至少一种。当然可以理解的，所述补偿层的材料不限于此。当设置补偿层时，中间厚度与边缘厚度之间的差值小于等于预设值（该预设值接近0），也即中间厚度与边缘厚度近似相等。其中所述中间厚度为位于所述中间区域101的曲面液晶显示面板的厚度；所述边缘厚度为位于所述边缘区域102的曲面液晶显示面板的厚度；换句话讲，所述补偿层40用于使所述曲面液晶显示面板的厚度一致，也即所述补偿层40用于减小所述曲面液晶显示面板的中间区域的厚度与所述边缘区域的厚度的差异。
其中，为了进一步提高穿透率，所述补偿层40的厚度根据所述中间间隙与预设间隙之间的差值设置。该预设间隙比如边缘间隙中的最大值或者说处于边缘区域的最大间隙，预设间隙比如为d2。
在一实施方式中，所述补偿层40的厚度与所述曲面液晶显示面板的弯曲曲率成正比。也即曲率越大的位置处的补偿层的厚度越厚。其中所述中间间隙的大小与所述曲面液晶显示面板的弯曲曲率的大小成反比。其中，为了进一步提高穿透率，如图2所示，所述补偿层40的厚度由中间向两侧逐渐减小。
多个补偿液晶分子50填充于所述第二基板20与所述补偿层40之间。可以理解的补偿液晶分子50随意地分布，不对其倾斜角进行限制，也即第二基板20与所述补偿层40之间分布有多种倾斜角度的补偿液晶分子。其中为了进一步降低色偏，所述补偿液晶分子50可为盘状液晶分子。所述偏转液晶分子11的长轴与短轴之间的比例大于所述补偿液晶分子50的长轴与短轴之间的比例。
如图3所示，偏转液晶分子11在电场作用下光线只能向固定方向a1-a3折射，当增加补偿液晶分子50后，由于补偿液晶分子具有多种倾斜角度，从而使得光线朝多个方向b1至bn折射，也即增多光线的出射角度，从而增多了液晶分子在各个视角上的透过率，进而增加中间区域的色彩饱和度，降低了色偏，提高了显示效果。
本实施例中，仅以所述曲面液晶显示面板沿第一预设方向（向下）弯曲举例说明，可以理解的当所述曲面液晶显示面板向上弯曲时，补偿层位于上基板的外侧，其结构与图2的相似。
返回图2，本发明的曲面液晶显示面板还包括封框胶22，其设置在第一基板10或者第二基板20的周缘。第一基板10可为阵列基板，第二基板20可为彩膜基板。当然，可以理解的，所述曲面显示面板还可包括两个或者两个以上的所述封框胶。当显示面板包括两个封框胶时，其中一个所述封框胶环绕在另一个所述封框胶外。
由于在第二基板弯曲曲率较大的位置的外侧设置补偿层，从而可以减小液晶盒厚度的差异，避免中间区域的穿透率降低，进而提高了整体的穿透率。此外，由于在第二基板和补偿层之间填充了补偿液晶分子，增多了光线的出射角度，也即增多了液晶分子在各个视角上的透过率，从而增加中间区域的色彩饱和度，降低了色偏，提高了显示效果。
本发明还提供一种显示装置，其包括上述曲面液晶显示面板。
本发明的曲面液晶显示面板及显示装置，通过在位于中间区域的第二基板中远离所述液晶层的一侧设置补偿层；所述第二基板与所述补偿层之间填充个多个补偿液晶分子，从而使得显示面板的厚度均匀，提高了穿透率，此外增加了光线的出射角度，降低了色偏，进而提高了显示效果。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
