附图说明
为了更清楚地说明本公开实施例或现有技术中的技术方案，下面将对实施例或现有技术描述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公开的一些实施例，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，还可以根据这些附图获得其他的附图。

具体实施方式
为了使本公开的目的，技术方案和优点更加清楚，下面结合附图，对本公开实施例提供的液晶显示面板、其制作方法及显示装置的具体实施方式进行详细地说明。
附图中各层薄膜厚度和形状不反映液晶显示面板的真实比例，目 的只是示意说明本公开内容。
目前采用电容式压感触控的方法有很多，例如，图1所示，一般采用在边框的位置设置一层压力材料1实现位置的探测，并且将该压力材料1位于显示面板2与背光源3之间，这样会影响显示面板2的厚度。图2所示的压力触摸屏，采用的是一种有机压电材料4，通过将压电电极5连接到栅极6上，通过研究不同压力下有机压电材料4改变栅极6的电压来确定压力大小和位置。但是相对于传统的触摸屏，该结构由于要增加压电电极5，因此增加工艺的复杂度，并且由于驱动和感应电压的实时驱动，因此触摸屏的功耗比较高。
因此，如何实现一种低功耗且膜厚较薄的压感触控功能的液晶显示面板是本领域技术人员亟需解决的问题。
本公开实施例提供的液晶显示面板，如图3a-3f、图4a-4f以及图5所示，包括：相对设置的第一基板01和第二基板02，位于第一基板01和第二基板02之间的用于支撑液晶显示面板盒厚的多个主隔垫物03、位于第一基板01和第二基板02之间的多个辅助隔垫物04(在附图中以一个主隔垫物03和一个辅助隔垫物04为例)、以及与所述多个辅助隔垫物04一一对应的多个压力感应电极05；其中所述辅助隔垫物04的高度小于所述主隔垫物03的高度；所述辅助隔垫物04的材料为压电材料。在所述液晶显示面板受到压力作用时，对应位置处的所述压力感应电极05与对应的辅助隔垫物04相接触。
本公开实施例提供的液晶显示面板，通过将液晶显示面板内的辅助隔垫物采用压电材料制成，当该液晶显示面板受到压力作用时，辅助隔垫物会被压缩，产生压电信号，对应位置的压力感应电极与辅助隔垫物相接触，压力感应电极会获取压电信号，从而实现液晶显示面板的压感触控功能。由于液晶显示面板内的辅助隔垫物是采用压电材料制成，因此辅助隔垫物可以复用为压力感应的触控层，不需要单独制作触控层，从而可以降低液晶显示面板的厚度及制作工艺，并且本公开中的辅助隔垫物只有在受到压力作用时才产生电荷，在未受到压力作用时是处于浮接状态的，因此可以降低液晶显示面板的功耗。
可选地，在本公开实施例提供的上述液晶显示面板中，如图3a-3f所示，所述多个压力感应电极05设置在所述二基板02面对所述第一基板01的一侧。事实上，在本公开实施例提供的上述液晶显示面板中， 所示第一基板01和第二基板02是可以互换的，因此，如图4a-4f所示，所述多个压力感应电极05也可以设置在所述二基板02面对所述第一基板01的一侧。
可选地，在本公开实施例提供的上述液晶显示面板中，如图3a所示，每个辅助隔垫物04设置在压力感应电极05面对所述第一基板01的一侧。类似地，在本公开实施例提供的上述液晶显示面板中，如图4a所示，每个辅助隔垫物04设置在压力感应电极05面对所述第一基板01的一侧。
可选地，在本公开实施例提供的上述液晶显示面板中，如图3b所示，还包括公共电极07；所述公共电极07设置在所述第二基板02面对所述第一基板01的一侧；所述公共电极07与所述多个压力感应电极05只采用一个掩模板形成，并且公共电极07通过可切换的开关071电连接至所述多个压力感应电极05。类似地，在本公开实施例提供的上述液晶显示面板中，如图4b所示，还包括公共电极07；所述公共电极07设置在所述第一基板01面对所述第二基板02的一侧；所述公共电极07与所述多个压力感应电极05只采用一个掩模板形成，并且公共电极07通过可切换的开关071电连接至所述多个压力感应电极05。图4b所示实施例的工作原理和图3b所示实施例的工作原理是类似的。
可选地，在本公开实施例提供的上述液晶显示面板中，如图3c所示，还包括公共电极07；所述公共电极07设置在所述第一基板01面对所述第二基板02的一侧。本领域技术人员能够理解，在图3c所示实施例的基础上，如图3d所示，还可以在所述第一基板01和所述公共电极07之间设置像素电极06，并在所述像素电极06和公共电极07之间设置绝缘层08。类似地，在本公开实施例提供的上述液晶显示面板中，如图4c所示，还包括公共电极07；所述公共电极07设置在所述第二基板02面对所述第一基板01的一侧。
可选地，在本公开实施例提供的上述液晶显示面板中，如图3e所示，所述多个辅助隔垫物04设置在所述第一基板01面对所述第二基板02的一侧。类似地，在本公开实施例提供的上述液晶显示面板中，如图4d所示，所述多个辅助隔垫物04设置在所述第二基板02面对所述第一基板01的一侧。
可选地，在本公开实施例提供的上述液晶显示面板中，如图3f所 示，还包括公共电极07；所述公共电极07设置在所述第一基板01面对所述第二基板02的一侧；所述多个辅助隔垫物04设置在所述公共电极07面对所述第二基板02的一侧。类似地，在本公开实施例提供的上述液晶显示面板中，如图4e所示，还包括公共电极07；所述公共电极07设置在所述第二基板02面对所述第一基板01的一侧；所述多个辅助隔垫物04设置在所述公共电极07面对所述第一基板01的一侧。本领域技术人员能够理解，在图4e所示实施例的基础上，如图4f所示，还可以在所述第一基板01和所述压力感应电极05之间设置像素电极06，并在所述压力感应电极05和所述像素电极06之间设置绝缘层09。利用以上的布置形式，当所述液晶显示面板受到压力作用时，受力位置处的辅助隔垫物会向压力感应电极05提供相应的电压，从而产生触控信号。
可选地，在本公开实施例提供的上述液晶显示面板中，所述第一基板01是阵列基板，所述第二基板02是对向基板(或，彩膜基板)。
可选地，在本公开实施例提供的上述液晶显示面板中，所述第一基板01是对向基板(或，彩膜基板)，所述第二基板02是阵列基板。
具体实施时，在本公开实施例提供的上述液晶显示面板中，一个压力感应电极对应一个辅助隔垫物，压力感应电极的材料可以为透明导电材料，也可以为金属材料，在此不作限定。
具体实施时，在本公开实施例提供的上述液晶显示面板中，当压力感应电极采用透明导电材料制作时，将透明导电材料制作为块状结构，即压力感应电极为块状电极；当压力感应电极采用金属材料制作时，为了增大透过率，一般将压力感应电极制作为网格状结构，即压力感应电极为金属网格状电极。
具体实施时，在本公开实施例提供的上述液晶显示面板中，主隔垫物的材料可以与辅助隔垫物的材料相同，也可以与辅助隔垫物的材料不相同，在此不作限定。
可选地，具体实施时，在本公开实施例提供的上述液晶显示面板中，主隔垫物的材料与辅助隔垫物的材料相同，这样主隔垫物与辅助隔垫物可以同层制备，即只采用一个掩模板形成主隔垫物与辅助隔垫物的图形，可以简化制备工艺流程，节省生产成本，提高生产效率。
具体实施时，在本公开实施例提供的上述液晶显示面板中，公共 电极与主隔垫物绝缘设置。可选地，压力感应电极与主隔垫物也绝缘设置，这样是因为主隔垫物在液晶显示面板中只起到支撑作用，由于主隔垫物的材料与辅助隔垫物的材料相同，均为压电材料，因此，当液晶显示面板受到压力作用时，主隔垫物产生电荷，对公共电极和压力感应电极上的信号会产生影响，从而影响液晶显示面板的显示和触控功能的判断。
具体实施时，在本公开实施例提供的上述液晶显示面板中，公共电极与主隔垫物绝缘设置可以是通过在公共电极与主隔垫物之间设置绝缘层实现，这样可以保证液晶显示面板受到压力作用时，主隔垫物只起到支撑作用，且主隔垫物产生电荷对公共电极上的信号不会产生影响，从而不会影响显示。但是设置绝缘层会增加液晶显示面板的制作成本和厚度。
具体实施时，在本公开实施例提供的上述液晶显示面板中，公共电极在阵列基板的正投影与主隔垫物在阵列基板的正投影不交叠，这样可以保证液晶显示面板受到压力作用时，主隔垫物只起到支撑作用，且主隔垫物产生电荷对公共电极上的信号不会产生影响。
具体实施时，在本公开实施例提供的上述液晶显示面板中，可以通过在公共电极在与主隔垫物对应的区域设置有过孔，以使当对向基板和阵列基板对盒后，主隔垫物与过孔对准。由此，确保所述主隔垫物不与公共电极接触，即公共电极在阵列基板的正投影与主隔垫物在阵列基板的正投影不交叠，来实现公共电极与主隔垫物绝缘设置，在此不作限定。
公开下面通过三个具体的实施例对本公开实施例提供的上述液晶显示面板的压感触控功能进行详细说明。
实施例一、
以公共电极位于阵列基板面向辅助隔垫物的一侧为例进行说明。
具体实施时，在本公开实施例提供的上述液晶显示面板中，如图3d所示，公共电极07位于第一基板01面向辅助隔垫物04的一侧；
压力感应电极05与辅助隔垫物04直接接触，且压力感应电极05与公共电极07隔离设置。
此处，“隔离设置”是指液晶显示面板在没有受到压力作用时，压力感应电极05与公共电极07之间具有一定距离。这样，当没有受 到压力作用时，压力感应电极05上就没有信号，当受到压力作用时，辅助隔垫物04与公共电极07接触而导通，从而产生压电信号，压力感应电极05上的信号就为公共电极07上的信号叠加压电信号。这样设置公共电极07可以增强压力感应电极05获取的触控信号，从而可以提高液晶显示面板的触控灵敏度。例如，设该压电信号为0.1V，设公共电极07上的信号为5V，从而压力感应电极05获取的信号为公共电极07上的信号与压电信号的叠加信号，即为5.1V，当随着触控压力的变化时，产生的压电信号也会发生变化，设产生的压电信号为0.15V，则压力感应电极05获取的信号为5.15V，即随着压力的变化，压力感应电极05获取的信号为公共电极07上的信号叠加压电信号，并且叠加的压电信号相对公共电极07上的信号变化不明显，不会对附近的像素显示造成影响。
可选地，具体实施时，在本公开实施例提供的上述液晶显示面板中，如图3d所示，压力感应电极05位于辅助隔垫物04面向对向基板02一侧。具体实施时，辅助隔垫物04一般制作在对向基板02上，因此先在对向基板02上制作压力感应电极05，然后再制作辅助隔垫物04，这样制作工艺比较简单。如果先在对向基板02上制作辅助隔垫物04，再制作压力感应电极05，由于辅助隔垫物04的高度相对较高，这样会增加工艺的制作难度。
实施例二、
以公共电极位于对向基板面向辅助隔垫物的一侧为例进行说明。
具体实施时，在本公开实施例提供的上述液晶显示面板中，如图4f所示，公共电极07位于对向基板02面向辅助隔垫物04的一侧；压力感应电极05位于辅助隔垫物04与像素电极06之间，且压力感应电极05与像素电极06相互绝缘，压力感应电极05与像素电极06通过位于压力感应电极05与像素电极06之间的绝缘层09绝缘。
具体实施时，在本公开实施例提供的上述液晶显示面板中，如图4f所示，辅助隔垫物04固定于对向基板02上；压力感应电极05与辅助隔垫物04隔离设置。
此处，“隔离设置”是指液晶显示面板在没有受到压力作用时，压力感应电极05与辅助隔垫物04之间具有一定距离。这样，当没有受到压力作用时，压力感应电极05上就没有信号，当受到压力作用时， 压力感应电极05与辅助隔垫物04接触而导通，从而产生压电信号，压力感应电极05上的信号就为公共电极07上的信号叠加压电信号。这样设置公共电极07可以增强压力感应电极05获取的触控信号，从而可以提高液晶显示面板的触控灵敏度。例如，设压电信号为0.1V，公共电极07上的信号为5V，从而压力感应电极05获取的信号就为5.1V，当随着压力的变化时，设产生的压电信号为0.15V，则压力感应电极05获取的信号为5.15V，即随着压力的变化，压力感应电极05获取的信号为公共电极07上的信号叠加压电信号，并且叠加的压电信号相对公共电极07上的信号变化不明显，不会对附近的像素显示造成影响。
实施例三、
具体实施时，在本公开实施例提供的上述液晶显示面板中，如图3b所示，公共电极07设置在所述第二基板02面对所述第一基板01的一侧；所述公共电极07与所述多个压力感应电极05只采用一个掩模板形成，并且公共电极07通过可切换的开关071电连接至所述多个压力感应电极05。这样不仅可以节省一层压力感应电极的制作工艺，而且可以减小液晶显示面板的厚度。这样设置可以增强压力感应电极05获取的触控信号，从而可以提高液晶显示面板的触控灵敏度。在显示阶段，可切换的开关071电连接所述公共电极07和所述多个压力感应电极05，所述公共电极07和所述多个压力感应电极05具有相同的电位。因此，在显示阶段，所述多个压力感应电极05还可以用作公共电极。在触控阶段，可切换的开关071是断开的，当液晶显示面板某个位置受到压力作用时，辅助隔垫物04由于受到压力的作用，产生压电信号，压力感应电极05上的信号就是压电信号，设该压电信号为0.1V，则压力感应电极05获取的信号就是0.1V。当压力变化时，设产生的压电信号为0.15V，则压力感应电极05获取的信号为0.15V。也就是说，随着压力的变化，压力感应电极05获取的信号为压电信号，并且压电信号不会显著影响公共电极07上的信号(即，公共电极07上的电压)，因此不会对附近的像素显示造成影响。
综上所述，本公开提供的上述三种实施例通过采用辅助隔垫物复用为触控层来实现液晶显示面板的压感触控功能，并且当没有受到压力作用时，压力感应电极处于浮接状态，因此可以达到降低液晶显示 面板功耗的功能。
具体实施时，在本公开实施例提供的上述液晶显示面板中，压电材料为有机压电材料，如聚偏二氟乙烯等，在此不作限定。
具体实施时，在本公开实施例提供的上述液晶显示面板中，如图5所示，还包括：位于对向基板02上的黑矩阵层10和多种颜色的光阻层11，以及覆盖黑矩阵层10和光阻层11的平坦化层12；其中，黑矩阵层10在第一基板01的正投影覆盖各辅助隔垫物04在阵列基板01的正投影。一般黑矩阵层10覆盖相邻的两个光阻层11之间的区域，即黑矩阵层10不占用显示区域，这样设置可以使辅助隔垫物04不占用像素单元的开口区域，从而不影响像素单元的开口率。
具体实施时，在本公开实施例提供的上述液晶显示面板中，如图5所示，还包括：位于第一基板01上的薄膜晶体管(Thin-film transistor，TFT)结构，由于该TFT结构与现有的结构相同，具体的制作工艺在此不做详述。
公开基于同一公开构思，本公开实施例还提供了一种液晶显示面板的制作方法，包括在第一基板上形成多个相互独立的压力感应电极的图形；在所述压力感应电极上形成辅助隔垫物的图形，以及在所述压力感应电极之间形成主隔垫物的图形；所述辅助隔垫物的高度小于所述主隔垫物的高度，所述辅助隔垫物的材料为压电材料；以及将所述第一基板和第二基板对盒。
可选地，在本公开实施例提供的上述液晶显示面板的制作方法中，还包括：在第二基板上形成公共电极的图形；其中所述公共电极在与所述主隔垫物对应的区域设置有过孔，以使当所述对向基板和所述阵列基板对盒后，所述主隔垫物与所述过孔对准。
具体实施时，可以先形成第一基板上所有的膜层，然后再形成第二基板上的所有的膜层，当然，也可以先形成第二基板上所有的膜层，然后再形成第一基板上的所有的膜层，在此不作限定。
具体实施时，在本公开实施例提供的上述液晶显示面板中，所述第一基板是阵列基板，所述第二基板是对向基板。在形成完对向基板上所有的膜层和形成完阵列基板上的所有的膜层之后，将对向基板和阵列基板对盒形成液晶显示面板。
可选地，在本公开实施例提供的上述液晶显示面板的制作方法中， 主隔垫物和辅助隔垫物的图形只采用一个掩模板形成。这样可以简化制备工艺流程，节省生产成本，提高生产效率。
可选地，在本公开实施例提供的上述液晶显示面板的制作方法中，如图6所示，主隔垫物和辅助隔垫物的图形只采用一个掩模板形成的步骤包括：601、采用涂覆的方式在形成有多个压力感应电极的第一基板上涂上一层有机压电材料的膜层；以及S602、通过对有机压电材料的膜层进行构图形成辅助隔垫物和主隔垫物的图形。
在具体实施时，可以采用灰色调或半色调掩膜板对有机压电材料的膜层进行构图，去除有机压电材料的膜层中与掩膜板的遮光区域对应的区域，在与掩膜板的完全透光区域对应的区域形成主隔垫物，在与掩膜板的部分透光区域对应的区域形成辅助隔垫物。
基于同一公开构思，本公开实施例还提供了一种显示装置，包括本公开实施例提供的上述任一种液晶显示面板。该显示装置解决问题的原理与前述液晶显示面板相似，因此该显示装置的实施可以参见前述液晶显示面板的实施，重复之处在此不再赘述。
在具体实施时，本公开实施例提供的显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。对于该显示装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本公开的限制。该显示装置的实施可以参见上述液晶显示面板的实施例，重复之处不再赘述。
本公开实施例提供的液晶显示面板、其制作方法及显示装置，通过将液晶显示面板内的辅助隔垫物采用压电材料制成，当该液晶显示面板受到压力作用时，辅助隔垫物会被压缩，产生压电信号，对应位置的压力感应电极与辅助隔垫物相接触，压力感应电极会获取压电信号，从而实现液晶显示面板的压感触控功能。由于液晶显示面板内的辅助隔垫物是采用压电材料制成，因此辅助隔垫物可以复用为压力感应的触控层，不需要单独制作触控层，从而可以降低液晶显示面板的厚度及制作工艺，并且本公开中的辅助隔垫物只有在受到压力作用时才产生电荷，在未受到压力作用时是处于浮接状态的，因此可以降低液晶显示面板的功耗。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不 脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
