本申请要求享有于2015年8月4日提交的名称为“蓝相液晶面板和蓝相液晶显示器”的中国专利申请CN201510470319.5的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本发明属于液晶显示技术领域，具体涉及蓝相液晶面板和蓝相液晶显示器。
背景技术
在现有的液晶显示技术领域中，蓝相液晶由于其自身的优良特性而被广泛应用于液晶显示器中。当液晶显示面板被施加电压后，在液晶显示面板的阵列基板上的像素电极和对置基板上的公共电极之间所形成的垂直电场的作用下，蓝相液晶将在垂直方向上被“拉伸”，而偏振光通过该垂直方向拉伸的蓝相液晶后，其并没有发生相位的改变，偏振光通过蓝相液晶后的偏振状态与蓝相液晶显示面板未施加电压时的偏振状态相同，又由于液晶显示面板的上、下偏光片的吸收轴相互垂直，因此背光源发出的光线无法通过液晶显示面板，从而无法得到液晶显示面板的亮态。综上所述，仅通过垂直电场是无法实现蓝相液晶显示面板各灰阶的显示的。
为了实现蓝相液晶显示面板的各灰阶的显示，同时降低蓝相液晶的驱动电压，需要提高液晶显示面板内的水平电场强度。目前业界通常采用优化电极结构的方式来达到该目的。在现有技术中，由于使用的IPS结构的驱动方式中，平行电极所产生的水平电场的穿透深度有限，因而仍然需要较高的驱动电压。
针对上述技术存在的问题，在本领域中希望寻求一种能够进一步减小蓝相液晶的驱动电压的蓝相液晶面板，以解决现有技术的不足之处。
发明内容
针对上述技术问题，本发明提供了一种蓝相液晶面板和一种蓝相液晶显示 器。
根据本发明提供的一种蓝相液晶面板，包括相对设置的上基板和下基板，以及设置在上基板和下基板之间的蓝相液晶。其中，上基板朝向蓝相液晶的一面设置有具有多个第一凸起的第一电极基层，下基板朝向蓝相液晶的一面设置有具有多个第二凸起的第二电极基层，各个第一凸起均延伸至相邻的两个第二凸起之间，各个第二凸起均延伸至相邻的两个第一凸起之间，并且第一凸起上设置有公共电极，第二凸起上设置有像素电极。
本发明在上基板和下基板上分别设置了第一电极基层和第二电极基层，将电极形成在相应的电极基层上即可实现液晶显示器的显示功能。通过对各个电极基层的结构进行设置，使其形成相应的电极以后能够增强IPS模式显示方式下的横向电场强度，或者形成类似VA模式显示方式下的斜向电场强度，从而降低蓝相液晶的驱动电压，以解决蓝相液晶所面临的驱动电压过大的问题。
在一些实施方案中，像素电极包括第一像素电极和第二像素电极，相邻两个第二凸起中的一个上设置有第一像素电极，另一个上设置有第二像素电极，第一像素电极与第二像素电极之间能够形成水平电场。该设置中，一方面第一像素电极和第二像素电极与公共电极之间均可形成电场，另一方面第一像素电极和第二像素电极之间还可形成水平电场，这便进一步提高了液晶面板内的水平电场强度，从而在进一步提高了光在蓝相液晶中的光透过率的同时减小了蓝相液晶的驱动电压。
在一些实施方案中，像素电极与下基板之间绝缘式设置有第二公共电极。通过这种设置使像素电极与公共电极、像素电极和第二公共电极之间均产生水平电场，第二公共电极的设置使液晶层内形成的电场具有更多的水平分量，从而使液晶层内在水平方向上具有更高的电场强度，该更高的电场强度使蓝相液晶内的液晶分子在水平方向上具有更大的光学异向性，进而减小了蓝相液晶的外部驱动电压。
在一些实施方案中，第二凸起采用导电材料制成，并设置成像素电极。该方案中的第二凸即为像素电极。
在一些实施方案中，第一凸起与第二凸起的截面形状均为三角形。通过调整第一凸起与第二凸起的相关参数，例如三角形的角度以及相邻第一凸起与第二凸起的间距，可进一步调整液晶面板内的电场方向以便形成斜向电场，从而达到减 小蓝相液晶的驱动电压的目的。
在一些实施方案中，第一凸起与第二凸起的截面形状均为矩形。具有矩形截面的第一凸起和第二凸起容易制作，通过控制矩形的第一凸起与第二凸起之间的横向间距和/或纵向间距来进一步调整液晶面板内的水平电场强度。
在一些实施方案中，公共电极完全覆盖第一电极基层，像素电极完全覆盖第二电极基层。
在一些实施方案中，第一电极基层包括第一基板，各个第一凸起间隔式设置在第一基板上，第二电极基层还包括第二基板，各个第二凸起间隔式设置在第二基板上。该方案中将各个第一凸起间隔式设置在第一基板上，各个第二凸起间隔式设置在第二基板上，使得第一电极基层与第二电极基层分别具有一体式的结构，这样一方面可以方便其设置在相应的基板上，另一方面便于第一电极基层与第二电极基层之间形成配合。
在一些实施方案中，第一基板上的对应于第二凸起的区域未设置公共电极，并且第二基板上的对应于第一凸起的区域未设置像素电极。该设置减弱了液晶面板中的竖直电场强度，增加了横向电场强度，横向电场强度的增加有利于蓝相液晶的液晶分子在水平方向上具有更大的光学异向性，从而提高了光在蓝相液晶中的光透过率并减小了蓝相液晶的驱动电压。
根据本发明提供的一种蓝相液晶显示器，包括上述蓝相液晶面板。该蓝相液晶显示器的蓝相液晶驱动电压较小，同时由于光在蓝相液晶中的光透过率较高，因此可以实现更好的显示效果。
与现有技术相比，本发明在上基板和下基板上分别设置了第一电极基层和第二电极基层，将电极形成在相应的电极基层上即可实现液晶显示器的显示功能。通过对各个电极基层的结构进行设置，使其覆盖相应的电极以后能够增强IPS模式显示方式下的横向电场强度，或者形成类似VA模式显示方式下的斜向电场强度，从而降低蓝相液晶的驱动电压，以解决蓝相液晶所面临的驱动电压过大的问题。另外，本发明的第一凸起和第二凸起设置成具有相互配合的结构，当按压液晶面板时，由于第一凸起和第二凸起之间不存在相互干涉的情况，因此不容易损坏电极。

具体实施方式
下面将结合附图对本发明作进一步说明。
这里所介绍的细节是示例性的，并仅用来对本发明的实施例进行例证性讨论，它们的存在是为了提供被认为是对本发明的原理和概念方面的最有用和最易理解的描述。关于这一点，这里并没有试图对本发明的结构细节作超出于基本理解本发明所需的程度的介绍，本领域的技术人员通过说明书及其附图可以清楚地理解如何在实践中实施本发明的几种形式。
图1显示了根据本发明的蓝相液晶面板100的第一实施例的结构示意图。该实施例中第一凸起111和第二凸起211的截面形状均为矩形。该蓝相液晶面板100包括相对设置的上基板10和下基板20，以及设置在上基板10和下基板20之间的蓝相液晶(图中未示出)。其中，上基板10朝向蓝相液晶的一面设置有具有多个第一凸起111的第一电极基层11，下基板20朝向蓝相液晶的一面设置有具有多个第二凸起211的第二电极基层21，各个第一凸起111均延伸至相邻的两个第二凸起211之间，各个第二凸起211均延伸至相邻的两个第一凸起111之间，并且第一凸起111上设置有公共电极40，第二凸起211上设置有像素电极50。这里所提到的第一电极基层11和第二电极基层21均由绝缘材料制成。
根据本发明，在上基板10和下基板20上分别设置了第一电极基层11和第二电极基层21，将电极形成在相应的电极基层上即可实现液晶显示器的显示功能。通过对第一电极基层11中的第一凸起111和第二电极基层21中的第二凸起211的结构进行设置，使第一凸起111和第二凸起211之间形成配合，再将相应 的电极覆盖在第一凸起111和第二凸起211上，使其能够增强IPS模式显示方式下的横向电场强度，从而降低蓝相液晶的驱动电压，以解决蓝相液晶所面临的驱动电压过大的问题。此外，当按压液晶面板100时，由于第一凸起111和第二凸起211之间不存在相互干涉的情况，因此不容易损坏设置在其表面的电极。
在如图1所示的实施例中，具有矩形截面的第一凸起111和第二凸起211容易制作，可通过控制矩形的第一凸起111与第二凸起211之间的横向间距和/或纵向间距来进一步调整液晶面板内的水平电场强度。
如图1所示，第一电极基层11优选包括第一基板112和间隔式设置在第一基板112上的多个第一凸起111，第二电极基层21包括第二基板212和间隔式设置在第二基板212上的多个第二凸起211。该方案中将各个第一凸起111间隔式设置在第一基板112上，各个第二凸起211间隔式设置在第二基板212上，使得第一电极基层11与第二电极基层21分别具有一体式的结构，这样一方面可以方便其设置在相应的玻璃基板上，另一方面便于第一电极基层11与第二电极基层21之间形成配合。
根据本发明，公共电极40可完全覆盖在第一电极基层11上，像素电极50可完全覆盖在第二电极基层21上。优选地，如图1所示的实施例中，第一基板112上与第二凸起211正对的区域未设置公共电极40，并且第二基板212上与第一凸起111正对的区域未设置像素电极50。该设置减弱了液晶面板100中的竖直电场强度，增加了横向电场强度，因此降低了蓝相液晶的驱动电压；同时，由于横向电场强度的增加有利于蓝相液晶的液晶分子在水平方向上具有更大的光学异向性，从而提高了光在蓝相液晶中的光透过率，以便实现蓝相液晶显示器100更好的显示效果。
优选地，如图2所示的实施例中，与图1所示的实施例的不同之处在于：像素电极包括第一像素电极50a和第二像素电极50b，相邻两个第二凸起211中的一个上设置有第一像素电极50a，另一个上设置有第二像素电极50b，第一像素电极50a与第二像素电极50b之间能够形成水平电场。该设置中，第一像素电极50a与第二像素电极50b分别由一个TFT控制，使第一像素电极50a与第二像素电极50b分别供给与之相对应的公共电极40方向相反并对称的控制信号，从而使第一像素电极50a与公共电极40之间、第二像素电极50b与公共电极40之间均可形成水平电场；同时，由于第一像素电极50a和第二像素电极50b之间存在电势差， 因此也可形成水平电场，这便进一步提高了液晶面板100内的水平电场强度，从而在进一步提高了光在蓝相液晶中的光透过率的同时减小了蓝相液晶的驱动电压。
如图3所示的实施例中，像素电极50c与下基板20之间绝缘式设置有第二公共电极30。在该实施方案中，第一凸起111的对应第二公共电极30的区域未设置公共电极40a，公共电极40a和第二公共电极30供给像素电极50c相同的公共信号，此时公共电极40和第二公共电极30之间不形成竖直电场，而是在像素电极50c与公共电极40之间、像素电极50c与第二公共电极30之间产生水平电场，因此第二公共电极30的设置使液晶层内形成的电场具有更多的水平分量，从而使液晶层内在水平方向上具有更高的电场强度，该更高的电场强度使蓝相液晶内的液晶分子在水平方向上具有更大的光学异向性，进而减小了蓝相液晶的外部驱动电压。
在如图4所示的实施例中，第二凸起211采用导电材料制成，并设置成如图3所示的像素电极50c，即在本实施例中，第二凸起211自身作为像素电极直接参与蓝相液晶的驱动。而公共电极30a也可设置成完全绝缘式覆盖在第二凸起211和下基板20之间，从而实现本发明。该方案中的第二凸即为像素电极。
根据本发明，如图5所示的实施例中，第一凸起111与第二凸起211的截面形状均为三角形。通过调整第一凸起111与第二凸起211的相关参数来具体调整蓝相液晶面板100内的电场强度。该相关参数例如可以是三角形凸起的角度以及相对的第一凸起111与第二凸起211的间距，即如图5所示的d1、d2和角度β的值。该方案在第一凸起111与第二凸起211之间均可形成斜向电场，该斜向电场改变了竖直电场不能驱动蓝相液晶的缺陷，同样能够增强横向电场强度，从而降低蓝相液晶的驱动电压。如图6所示的实施例中，与图5所示的实施例的不同之处在于：像素电极50可部分形成在第二凸起211上。
如图7所示的实施例中，在第二凸起211上的像素电极还可设置成第一像素电极50d和第二像素电极50e交替排列。在该设置中，第一像素电极50d与第二像素电极50e分别由一个TFT控制，使第一像素电极50d与第二像素电极50e分别供给与之相对应的公共电极40方向相反并对称的控制信号，从而使第一像素电极50d与公共电极40之间、第二像素电极50e与公共电极40之间均可形成斜向电场；同时，由于第一像素电极50d和第二像素电极50e之间存在电势差，因 此也可形成部分斜向电场，这便使蓝相液晶的液晶分子具有更大的光学异向性，从而在进一步提高了光在蓝相液晶中的光透过率的同时减小了蓝相液晶的驱动电压。
可以理解的是，本发明的第一凸起和第二凸起的形状和设置方式并不局限于这里所介绍的矩形或者三角形的截面形状，也可以设置成其他能够使液晶面板具有更小的驱动电压的其他形状。
根据本发明提供的一种蓝相液晶显示器，包括上述蓝相液晶面板。该蓝相液晶显示器的蓝相液晶驱动电压较小，同时可以实现更好的显示效果。其工作原理与现有的蓝相液晶显示器相同，这里不再赘述。
应注意的是，前面所述的例子仅以解释为目的，而不能认为是限制了本发明。虽然已经根据示例性实施例对本发明进行了描述，然而应当理解，这里使用的是描述性和说明性的语言，而不是限制性的语言。在当前所述的和修改的所附权利要求的范围内，在不脱离本发明的范围和精神的范围中，可以对本发明进行改变。尽管这里已经根据特定的方式、材料和实施例对本发明进行了描述，但本发明并不仅限于这里公开的细节；相反，本发明可扩展到例如在所附权利要求的范围内的所有等同功能的结构、方法和应用。
