Description

液晶面板、液晶显示器及液晶面板的制备方法
本发明要求2016年6月2日递交的发明名称为“液晶面板、液晶显示器及液晶面板的制备方法”的申请号201610387776.2的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及显示技术领域，尤其涉及一种液晶面板、一种应用所述液晶面板的液晶显示器以及一种液晶面板的制备方法。
背景技术
近年来，薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)在手机、电脑等电子显示设备上得到了广泛的应用。薄膜晶体管液晶显示器包含液晶面板，液晶面板包括彩膜基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)和薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFT Substrate)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal，LC)。液晶面板是通过电场对液晶分子取向的控制，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。
为防止静电电荷(electrostatic charge)对液晶面板内电场的影响，通常会在彩膜基板与偏光片之间设置一个透明的面状导电屏蔽层，然后通过点银胶，将屏蔽层电连接至薄膜晶体管阵列基板侧的接地点，从而来避免产生静电mura，造成显示不良。然而，上述方式需要点银胶制程，且银胶覆盖的段差大，有断裂的风险，从而使得液晶面板仍可能受到静电击伤。
发明内容
本发明所要解决的技术问题在于提供一种具有静电防护性能的液晶面板。
此外，本发明还提供一种采用所述液晶面板的液晶显示器。
另外，本发明还提供一种液晶面板的制备方法，用于制备所述液晶面板。
为了实现上述目的，本发明实施方式采用如下技术方案：

附图说明
为了更清楚地说明本发明的技术方案，下面将对实施方式中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以如这些附图获得其他的附图。
图1是本发明实施例提供的一种液晶面板的结构示意图。
图2至图6是本发明实施例提供的一种液晶面板的制备方法中各个步骤所对应的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，本发明实施例提供一种液晶面板，包括彩膜基板1、阵列基板2、框胶3以及液晶层4。其中，所述彩膜基板1形成显示区100和围设在 所述显示区100周边的非显示区200，所述彩膜基板1包括多个色阻模块11和平坦层12，所述多个色阻模块11呈矩阵排布在所述显示区100内，所述平坦层12包括屏蔽层121和连接所述屏蔽层121的多个第一色阻122，所述多个第一色阻122与所述多个色阻模块11交替排布在所述显示区100内，所述屏蔽层121覆盖所述多个色阻模块11，所述平坦层12中添加有导电聚合物120。所述阵列基板2与所述彩膜基板1相对设置，所述阵列基板2包括正对所述非显示区200设置的接地焊垫21。所述框胶3连接所述阵列基板2和所述彩膜基板1的所述非显示区200，用以密封夹持于所述彩膜基板1与所述阵列基板2之间的液晶层4，所述框胶3中添加有导电微粒31，并且所述框胶3连接所述平坦层12以及所述接地焊垫21，用以使所述平坦层12接地。
在本实施例中，所述液晶面板的所述平坦层12添加有导电聚合物120，所述框胶3添加有导电微粒31，并且所述框胶3连接所述平坦层12以及所述阵列基板2的接地焊垫21，因此所述平坦层12接地。由于所述平坦层12的所述屏蔽层121连接所述多个第一色阻122且覆盖所述多个色阻模块11，因此所述平坦层12覆盖所述显示区100。当外界静电接触到所述液晶面板时，借由所述平坦层12以及所述框胶3，可快速地将静电电荷释放至地，从而避免外界静电对所述液晶面板造成静电损伤。同时，由于所述平坦层12、所述框胶3以及所述接地焊垫21均位于所述阵列基板2与所述彩膜基板1之间，彼此之间的连接牢固、不易损坏，因此所述液晶面板具有可靠静电防护性能。再者，由于所述平坦层12的所述多个第一色阻122参与所述液晶面板的显示工作，因此当所述平坦层12形成在所述液晶面板内时，所述平坦层12额外占用的空间很小，有利于所述液晶面板的小型化和薄型化发展。
应当理解的，所述平坦层12采用色阻材料作为基材，并在所述基材中添加导电聚合物120，用以使所述平坦层12具有导电性能。同时，由于所述平坦层12置于所述彩膜基板1与所述阵列基板2之间，因此降低了所述平坦层12受到刮伤损害的风险，可适当放宽所述平坦层12所采用的色阻材料的硬度要求，所述平坦层12可选用的色阻材料范围更大。本实施例减少了点银胶制程，提高了生产效率。
请参阅图1，在本实施例中，所述“交替排布”是指在单一方向上，所述 多个色阻模块11与所述多个第一色阻122一一交替地轮流排布，例如“一个所述色阻模块11-一个所述第一色阻122-一个所述色阻模块11-一个所述第一色阻122”的交替方式。此时，本实施例并不限定所述多个色阻模块11与所述多个第一色阻122在垂直于所述单一方向上的另一方向上的排布方式，可以依据具体应用的需求，设置成“一个所述色阻模块11-一个所述第一色阻122-一个所述色阻模块11-一个所述第一色阻122”的交替方式，或者“一个所述色阻模块11-一个所述色阻模块11”且“一个所述第一色阻122-一个所述第一色阻122”的重复方式。
进一步地，请参阅图1，可选的，每一个所述色阻模块11均包括第二色阻111、第三色阻112以及第四色阻113，所述第二色阻111为红色色阻(R，red)，所述第三色阻112为绿色色阻(G，green)，所述第四色阻113为蓝色色阻(B，blue)，所述多个第一色阻122为白色色阻(W，white)或者黄色色阻(Y，yellow)。因此，当所述多个第一色阻122为白色色阻时，本实施例所述液晶面板采用RGBW显示技术；当所述多个第一色阻122为黄色色阻时，本实施例所述液晶面板采用RGBY显示技术。
可以理解的，本实施例所述平坦层12既起到静电屏蔽作用，同时还与RGB色阻相组合以使所述液晶面板实现RGBW显示或RGBY显示，使得所述液晶面板具有高色域、低功耗性能。
在本实施例中，所述第二色阻111、所述第三色阻112以及所述第四色阻113依次连接排布。应当理解的，在其他实施方式中，所述第二色阻111、所述第三色阻112以及所述第四色阻113也可以有其他排布方式。
进一步地，请参阅图1，可选的，所述屏蔽层121可同时覆盖所述多个色阻模块11和所述多个第一色阻122，也即所述屏蔽层121可形成一个完整的覆盖面，进而覆盖所述显示区100。此时，所述屏蔽层121与所述多个第一色阻122的连接关系更为可靠。并且，所述屏蔽层121朝向所述液晶层4的表面也能够具有很好的平面度，以方便后续工艺的进行，提高所述液晶面板的良率。
进一步地，可选的，所述导电聚合物120包括3,4-乙烯二氧噻吩的聚合物(PEDOT，3,4-ethylenedioxythiophene)。当然，在其他实施例中，所述导电聚合物120也可以是其他具有导电性能的材质。
进一步地，可选的，所述导电微粒31包括金球和/或碳粉。当然，在其他实施例中，所述导电微粒31也可以是其他具有导电性能的材质。
进一步地，可选的，所述阵列基板2上集成有触摸传感器(图中未示出)，用以使所述液晶面板实现触摸控制。也即，本实施例所述液晶面板可以为内嵌式(in-cell)触控面板。
本发明实施例还提供一种液晶显示器，包括如前述任一实施例所述的液晶面板。本实施例所述液晶显示器，由于采用前述实施例所述液晶面板，因此具有可靠的静电防护性能。特别的，所述液晶显示器为触控型液晶显示器。
请一并参阅图2至图6，本发明实施例还提供一种液晶面板的制备方法，包括：
步骤Step1：提供基板10，所述基板10包括显示区100和围设在所述显示区100周边的非显示区200，如图2所示；
步骤Step2：在所述显示区100上制备呈矩阵排布的多个色阻模块11，如图3所示；
步骤Step3：在所述显示区100上制备添加有导电聚合物120的平坦层12，所述平坦层12包括屏蔽层121和连接所述屏蔽层121的多个第一色阻122，所述多个第一色阻122与所述多个色阻模块11交替排布，所述屏蔽层121覆盖所述多个色阻模块11，以形成彩膜基板1，如图4所示；
步骤Step4：在所述非显示区200上形成添加有导电微粒31的框胶3，所述框胶3连接所述平坦层12，如图5所示；以及
步骤Step5：提供阵列基板2，对盒所述阵列基板2与所述彩膜基板1，并使所述框胶3连接所述阵列基板2的接地焊垫21，在所述彩膜基板1、所述阵列基板2以及所述框胶3所围设出的空间内填充液晶层4，以形成液晶面板，如图6所示。
进一步地，请参阅图4，步骤Step3中所述“在所述显示区100上制备添加有导电聚合物120的平坦层12”包括：
Step31：在色阻材料中添加导电聚合物120，以形成平坦层涂料；
Step32：在所述显示区100上涂布一层所述平坦层涂料，一体形成所述多个第一色阻122以及所述屏蔽层121，以形成所述平坦层12。
依本实施例所述制备方法进行生产的液晶面板，其所述平坦层12添加有导电聚合物120，所述框胶3添加有导电微粒31，并且所述框胶3连接所述平坦层12以及所述阵列基板2的接地焊垫21，因此所述平坦层12接地。由于所述平坦层12的所述屏蔽层121连接所述多个第一色阻122且覆盖所述多个色阻模块11，因此所述平坦层12覆盖所述显示区100。当外界静电接触到所述液晶面板时，借由所述平坦层12以及所述框胶3，可快速地将静电电荷释放至地，从而避免外界静电对所述液晶面板造成静电损伤。
在本实施例中，所述平坦层12一体成型，所述多个第一色阻122与所述屏蔽层121采用相同的物料，减少了所述液晶面板的制备方法中所涉及的物料种类，且简易了工艺步骤，实现工艺优化。
应当理解的，由于所述平坦层12的制程整合在所述彩膜基板1的制程中，因此所述液晶面板的制备方法得以优化，提升了所述液晶面板的生产效率。
进一步地，可选的，所述导电聚合物120包括3,4-乙烯二氧噻吩的聚合物(PEDOT，3,4-ethylenedioxythiophene)，所述导电微粒31包括金球和/或碳粉。
以上对本发明实施例进行了详细介绍，本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
