Description

显示面板和显示器件
本申请要求于2021年10月15日在中国专利局提交的、申请号为202111200793.8、申请名称为“显示面板和显示器件”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板和显示器件。
 背景技术
Trace Mura（压痕）可以理解为一种刮痕亮度不均现象，是指用硬质部件在显示器表面划刮后，在不破坏表面膜层的前提下，显示器上会沿着划刮位置的路线出现Mura（亮度不均）的现象，并且在短时间内Mura无法消失。Trace Mura产生的原理是当显示面板受到压力时，受压位置倾角较大的液晶分子受挤压重新排列，使光透过率发生变化，当压力撤销后，重新排列的液晶分子在电场的作用力下无法在短时间内回到原始的位置，从而影响显示效果，最终会影响产品品质。

 有益效果
本申请实施例提供的显示面板有益效果在于该显示面板的第一基板和第二基板之间的隔垫物内分散有导电材料，而且该隔垫物与第一基板上的像素电极接触；因隔垫物的本体是不导电的有机材料，在没有外力作用下，隔垫物是绝缘体，当隔垫物在外力作用受挤压后本体被压缩，其中的导电材料部分相互接触可使隔垫物由绝缘体变成导体，隔垫物受挤压转变为导体之后，会使受压部位的像素电极的信号衰减，这样可以利用加载（Loading）损耗来使受压部位的信号电压减小，避免受压部位的液晶分子重排，从而可以避免产生Trace Mura现象，最终提升该显示面板的产品品质。
本申请实施例提供的显示器件的有益效果在于该显示器件包括本申请特有的显示面板，该显示面板的液晶层的隔垫物内分散有导电材料，而且该隔垫物与第一基板上的像素电极接触；因该隔垫物受外力作用压缩后由绝缘体转变为导体，受压部位的像素电极信号会衰减，从而利用Loading损耗来使受压部位的信号电压减小，避免受压部位的液晶分子重排，从而可以避免产生Trace Mura，最终可以提高该显示器件的产品品质。

术语“第一”、“第二”仅用于描述目的，用来将目的如物质彼此区分开，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。例如，在不脱离本申请实施例范围的情况下，第一XX也可以被称为第二XX，类似地，第二XX也可以被称为第一XX。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
第一实施例：
本实施例提供一种显示面板，如图1和图2所示，该显示面板包括：
第一基板10；
第二基板20，与第一基板10相对设置；
液晶层30，位于第一基板10和第二基板20之间；
其中，第一基板10靠近液晶层30的表面设有像素电极11，第一基板10和第二基板20之间设有隔垫物31，隔垫物31与像素电极11接触，隔垫物31包括本体311和分散在本体311中的导电材料312，本体311受挤压后导电材料312相互接触，以使隔垫物31由绝缘体变成导体。
本实施例提供的显示面板，隔垫物31内分散有导电材料312，而且该隔垫物31与第一基板10上的像素电极11接触；因隔垫物31的本体311是不导电的有机材料，在没有外力作用下，隔垫物31是绝缘体，如图1所示；当隔垫物31在外力作用受挤压后本体311被压缩，如图2所示，其中的导电材料312部分相互接触可使隔垫物31由绝缘体变成导体，隔垫物31受挤压转变为导体之后，会使受压部位的像素电极11信号衰减，这样可以利用加载（Loading）损耗来使受压部位的信号电压减小，避免受压部位的液晶分子301重排，从而可以避免产生Trace Mura，最终提升显示面板产品品质。
具体地，第一基板10可以是阵列基板，第二基板20可以是彩膜基板。更具体地，隔垫物31可以是主隔垫物，这样主隔垫物的一端与第一基板10抵接，另一端与第二基板20抵接，同时主隔垫物与第一基板10上的像素电极11接触，这样设置可以使隔垫物31对产生Mura的外力具有更好的感应，此时，隔垫物31可以设置在第一基板10上，也可以设置在第二基板20上。当然，隔垫物31可以是辅隔垫物，这样辅隔垫物的一端与第一基板10抵接，另一端可以不与第二基板20接触，此时，隔垫物31是设置在第一基板10上。
具体地，隔垫物（Spacer）31中的本体311为不导电的有机材料，一般选择树脂类的有机材料，例如，可以选自丙烯类树脂、乙烯丙烯弹性树脂、聚酯树脂等；更具体地，该隔垫物31可以是光阻隔垫物（Photo Spacer，PS）。
隔垫物31的厚度（即在第一基板10和第二基板20之间的高度）可以为2μm-6μm，隔垫物31的形状可以是圆形、椭圆形、圆台形或圆柱形等，具体尺寸不做限定，例如可以是10μm×10μm~40μm×40μm。由于隔垫物31相对电极层来说厚度较厚，体积较大，当隔垫物31受挤压压缩后转变为导体，会使按压部位像素电极11的信号衰减，如图3所示，从而造成实际的电压信号减小，从而避免按压部位的液晶分子301重排，避免产生Trace Mura。
需要说明是，本申请中所说的力或受压，一般是指目前能产生Mura的外力，其对应有一个阈值。当不受外力作用或所受外力小于该阈值时，本申请显示面板内的隔垫物31内分散的导电材料312大都相互分离，隔垫物31不导电；当外力大于或等于该阈值时，本申请显示面板内的隔垫物31的本体311被压缩，原本分散的导电材料312至少部分相互接触，从而实现隔垫物31变成导体，当外力再次撤走时，本体311恢复原状，分散的导电材料312再次相互分离使隔垫物31绝缘。
具体地，隔垫物31内的导电材料312选自金属纳米颗粒和碳纳米材料中的至少一种。具体地，其中金属纳米颗粒选自金纳米颗粒、银纳米颗粒、铜纳米颗粒和铝纳米颗粒中的至少一种，所述碳纳米材料选自碳纳米管和石墨烯纳米片中至少一种。上述金属纳米颗粒和碳纳米材料可以很好地分散在隔垫物31的本体311内，而且相互接触时具有很好的导电性能。在一个实施例中，隔垫物31内的导电材料312占本体311的体积百分比为10%~40%，即该导电材料312的总体积占本体311的总体积的10%~40%，在上述体积占比条件下，隔垫物31受压可以更好地实现导电材料312接触，从而变成导体。
导电材料312的尺寸以满足在隔垫物31的厚度范围内分散为准。例如，导电材料312选自金属纳米颗粒时，金属纳米颗粒的粒径可以为100nm~1000nm；导电材料312选自碳纳米管或石墨烯纳米片时，碳纳米管尺寸可以为2nm×100nm~100nm×1μm；石墨烯纳米片尺寸可以为2nm×200nm~20nm×1μm。需要说明的是，本申请所说的纳米级材料，可以是指尺寸在1nm~1000nm之间的材料。
第二实施例：
本实施例提供一种显示面板，如图4和图5所示，该显示面板包括：第一基板10；第二基板20，与第一基板10相对设置；液晶层30，位于第一基板10和第二基板20之间；其中，第一基板10靠近液晶层30的表面设有像素电极11，第一基板10和第二基板20之间设有隔垫物31，隔垫物31的一端与第一基板10抵接，另一端与第二基板20抵接，隔垫物31与像素电极11接触，隔垫物31与像素电极11的接触部分设有导电薄膜32；隔垫物31包括本体311和分散在本体311中的导电材料312，本体311受挤压后导电材料312相互接触，以使隔垫物31由绝缘体变成导体。
隔垫物该连续导电薄膜32是一种平整的无缺口的导电膜层，当隔垫物31在外力作用受挤压后，导电材料312至少部分相互接触使隔垫物31由绝缘体变成导体，此时该导电薄膜32可以更好地增加隔垫物31与像素电极11接触时的导电性。此外，前述第一实施例的隔垫物31的本体311和导电材料312的材料、厚度等可选的方案均可以用于图4所示的显示面板中，该显示面板具有上述第一实施例提供隔垫物31的所有优势，在此不再赘述。
第三实施例：
本实施例提供一种显示面板，如图6和图7所示，该显示面板包括：第一基板10；第二基板20，与第一基板10相对设置；液晶层30，位于第一基板10和第二基板20之间；其中，第一基板10靠近液晶层30的表面设有像素电极11，第一基板10和第二基板20之间设有隔垫物31，隔垫物31的一端与第一基板10抵接，另一端与第二基板20抵接，隔垫物31与像素电极11接触，隔垫物31与像素电极11的接触部分设有导电的尖端结构33，该尖端结构33的尖端朝向隔垫物31；隔垫物31包括本体311和分散在本体311中的导电材料312，本体311受挤压后导电材料312相互接触，以使隔垫物31由绝缘体变成导体。
该尖端结构33可以是一层导电的尖端状材料，设于隔垫物31与像素电极11之间，尖端结构33尖端朝向隔垫物31。当隔垫物31在外力作用受压后，导电材料312至少部分相互接触使隔垫物31由绝缘体变成导体，同时尖端结构33可以刺穿相邻的隔垫物31表面，与隔垫物31内的导电材料312接触导通，从而可以进一步增加隔垫物31与像素电极11的导电性。此外，前述第一实施例的隔垫物31的本体311和导电材料312的材料、厚度等可选的方案均可以用于图6所示的显示面板中，该显示面板具有上述第一实施例提供隔垫物31的所有优势，在此不再赘述。
第四实施例：
本实施例提供一种显示面板，如图8所示，该显示面板包括：第一基板10；第二基板20，与第一基板10相对设置；液晶层30，位于第一基板10和第二基板20之间；其中，第一基板10靠近液晶层30的表面设有像素电极11，第一基板10和第二基板20之间设有隔垫物31，隔垫物31的一端与第一基板10抵接，另一端与第二基板20抵接，隔垫物31与像素电极11接触，隔垫物31包括本体311和分散在本体311中的导电材料312，而且该隔垫物31包括与像素电极11接触的第一端部313以及与像素电极11非接触的第二端部；其中，第一端部313中导电材料的体积百分比为20%~60%，第二端部314中导电材料的体积百分比为5%~20%。例如，可以将隔垫物31分成厚度相同的第一端部313和第二端部314，因第一端部313中导电材料的体积分布密度大于第二端部314中导电材料的体积分布密度，这样当隔垫物31在外力作用受挤压后，可以更好地增加隔垫物31与像素电极11接触时的导电性。
具体地，上述隔垫物31第一端部313中导电材料的粒径大于第二端部314中导电材料的粒径。例如，以金属纳米颗粒为例，第一端部313中的金属纳米颗粒粒径可以为500nm~800nm，第二端部314中的金属纳米颗粒粒径可以为100nm~400nm；如此，隔垫物31在外力作用受压后，可以进一步增加隔垫物31与像素电极11接触时的导电性。
第五实施例：
本实施例提供一种显示器件，如图9所示，显示器件包括显示面板和用于为显示面板提供照明的背光模组40，具体地，显示面板包括：第一基板10；第二基板20，与第一基板10相对设置；液晶层30，位于第一基板10和第二基板20之间，第一基板10靠近液晶层30的表面设有像素电极11，第一基板10和第二基板20之间设有隔垫物31，隔垫物31与像素电极11接触，隔垫物31包括本体311和分散在本体311中的导电材料312，本体311受挤压后导电材料312相互接触，以使隔垫物31由绝缘体变成导体。
本实施例提供的显示器件包括本申请实施例特有的显示面板，该显示面板的液晶层30的隔垫物31内分散有导电材料312，而且该隔垫物31与第一基板10上的像素电极11接触；因该隔垫物31受力作用由绝缘体转变为导体，使受力部位的像素电极11信号衰减，从而利用Loading损耗来使受压部位的信号电压减小，避免按压部位的液晶分子重排，从而可以避免产生Trace Mura，最终可以提高显示器件的产品品质。
具体地，本申请实施例提供的显示器件中可以设置有上述第一实施例、第二实施例、第三实施例、以及第四实施例提供的显示面板，因此，上述显示面板可选的方案均可以用于该显示器件中，显示器件具有上述实施例提供的显示面板的所有优势，在此不再赘述。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
