Description

用于曲面显示装置的液晶面板及曲面显示装置
本申请要求享有2015年10月8日提交的名称为“用于曲面显示装置的液晶面板及曲面显示装置”的中国专利申请CN201510645400.2的优先权，其全部内容通过引用并入本文中。
技术领域
本发明涉及显示技术领域，具体地说，涉及一种用于曲面显示装置的液晶面板及曲面显示装置。
背景技术
曲面显示装置具有曲面形的显示屏，由于能够实现屏幕各个像素点到达人眼的距离相等，更能逼真还原人眼真实视觉感受，所以使其与传统平板显示装置相比具有更强的竞争力。
曲面显示装置的制造过程是，先分别制造平面形的阵列基板和彩膜基板，然后将阵列基板和彩膜基板进行对盒，形成平面形的液晶面板，再将平面形的液晶面板进行弯曲，形成内凹形的曲面液晶面板。如图1所示，彩膜基板1上设置有多个柱状的隔垫物11，阵列基板2上对应设置有多个凸台21。在彩膜基板1和阵列基板2对盒后，隔垫物11的末端就能够抵靠在凸台21上，从而起到支撑作用，使液晶面板能够保持一定的厚度。
但是，当平面形的液晶面板被弯曲之后，彩膜基板1和阵列基板2会发生相对移动。对于液晶面板中的不同位置，彩膜基板1和阵列基板2相对移动的方向不同，如图2所示，在液晶面板左侧，彩膜基板1会相对阵列基板2向左移动；在液晶面板右侧，彩膜基板1会相对阵列基板2向右移动。这也会使隔垫物11与凸台21之间发生错位，使隔垫物11的末端不能抵靠在凸台21上，导致液晶面板的盒厚不均而引起显示不良的技术问题。
发明内容
本发明的目的在于提供一种用于曲面显示装置的液晶面板及曲面显示装置，以解决现有的曲面显示装置容易出现盒厚不均而引起显示不良的技术问题。
本发明提供一种用于曲面显示装置的液晶面板，包括上基板和下基板；
所述上基板上设置有多个隔垫物，所述下基板上设置有与所述隔垫物一一对应的凸台；
其中，部分或全部隔垫物相比于与其对应的凸台，至所述液晶面板的中轴线之间的距离更短。
优选的是，任一隔垫物相比于与其对应的凸台，至所述液晶面板的中轴线之间的距离之差在20微米以内。
进一步的是，从所述液晶面板的中间至两端，所述距离之差逐渐增大。
进一步的是，所述上基板上还设置有多个辅助隔垫物。
优选的是，所述辅助隔垫物的数量是所述隔垫物的数量的8至12倍。
进一步的是，所述上基板为彩膜基板，所述下基板为阵列基板。
优选的是，所述凸台设置在薄膜晶体管所在位置。
本发明还提供一种曲面显示装置，包括由上述的液晶面板弯曲形成的曲面液晶面板。
本发明带来了以下有益效果：本发明提供的液晶面板中，将上基板上的隔垫物设置距离中轴线较近的位置，而下基板上的与隔垫物对应的凸台设置在距离中轴线较远的位置。将该液晶面板进行弯曲之后，由于上基板与下基板之间的相对移动，隔垫物与凸台就能够准确对位，使隔垫物的末端恰好抵靠在凸台上，从而保持弯曲后的液晶面板的盒厚，避免了因为盒厚不均而引起显示不良的技术问题。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要的附图做简单的介绍：
图1是现有的曲面显示装置中液晶面板弯曲前的示意图；
图2是现有的曲面显示装置中液晶面板弯曲后的示意图；
图3a和图3b分别是本发明实施例提供的液晶面板的左侧和右侧的隔垫物与凸台的示意图；
图4是本发明实施例提供的液晶面板弯曲后的示意图。
具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
本发明实施例提供一种用于曲面显示装置的液晶面板，主要包括上基板和下基板。本实施例以最为常见的液晶面板的构成为例进行说明，即上基板为彩膜基板，下基板为阵列基板，并且彩膜基板与阵列基板之间填充有液晶。
本实施例中，彩膜基板上设置有多个隔垫物；阵列基板上设置有与隔垫物一一对应的凸台，这些凸台即是阵列基板各层结构的最高处。作为一个优选方案，凸台可以设置在薄膜晶体管所在位置，因为薄膜晶体管处的层结构通常最为复杂，所以薄膜晶体管所在位置通常就是阵列基板的最高处。
其中，部分或全部隔垫物相比于与其对应的凸台，至液晶面板的中轴线之间的距离更短。也就是说，隔垫物距离中轴线更近，而与该隔垫物对应的凸台则较远离中轴线。
如图3a所示，在液晶面板的左侧，隔垫物10的位置相比于与其对应的凸台10，更加偏向右侧。如图3b所示，在液晶面板的右侧，隔垫物10的位置相比于与其对应的凸台20，更加偏向左侧。
其中，任一隔垫物10相比于与其对应的凸台20，至中轴线之间的距离之差在20微米以内，通常该距离之差可选为几微米或十几微米。该距离之差具体的数值，应当根据液晶面板的尺寸、弯曲度等实际参数进行精确测算。
进一步的是，从液晶面板的中间至两端，隔垫物10与对应的凸台20之间的距离之差逐渐增大，即隔垫物10与凸台20之间的距离逐渐增大。如图4所示，因为在液晶面板被弯曲之后，越靠近液晶面板的两端，彩膜基板100与阵列基板200之间的错位程度就越大，所以在液晶面板的两端处，相应的增加隔垫物10与凸台20之间的距离。这样就能够使液晶面板在弯曲之后，各处的隔垫物10与凸台20都能准确对位，使隔垫物10的末端恰好抵靠在凸台20上，从而保持弯曲后的液晶面板的盒厚，避免了因为盒厚不均而引起显示不良的技术问题。
应当说明的是，在液晶面板的中间区域，也就是液晶面板的中轴线附近，隔垫物与凸台在液晶面板弯曲之后发生相对位移的程度很小，或者不会发生相对位移。因此，在液晶面板的中间区域中，隔垫物和凸台至中轴线的距离可以相等，即隔垫物可以不需要向中轴线偏移。
当然，在对液晶面板的盒厚要求较高的情况下，也可以对所有的隔垫物都进行偏移， 使所有的隔垫物相比于对应的凸台都更靠近中轴线。
进一步的是，本实施例中的彩膜基板100上还设置有多个辅助隔垫物(图中未示出)。而本实施例之前所描述的向中轴线偏移的隔垫物10，也可以称为主隔垫物。其中，辅助隔垫物的数量是主隔垫物的数量的8至12倍。
在彩膜基板与阵列基板对盒之后，在一般情况下，仅主隔垫物与阵列基板上的凸台接触，起到主要支撑作用，保持彩膜基板与阵列基板之间的盒厚，而次隔垫物与阵列基板不接触。当彩膜基板受到外部压力时，次隔垫物才会与阵列基板相接触，从而起到辅助支撑作用。
本发明实施例还提供一种曲面显示装置，其中包括由上述本发明实施例提供的液晶面板弯曲形成的曲面液晶面板。该曲面显示装置通常为大尺寸的液晶电视，具体可以达到49寸、55寸或者更大的尺寸。
因为本发明实施例提供的曲面显示装置中，包含上述实施例提供的液晶面板的全部技术特征，所以也能解决相同的技术问题，达到相同的技术效果。
虽然本发明所公开的实施方式如上，但所述的内容只是为了便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所公开的精神和范围的前提下，可以在实施的形式上及细节上作任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
