Description

一种液晶显示面板及装置
【技术领域】
本发明涉及显示器技术领域，特别是涉及一种液晶显示面板及装置。
【背景技术】
随着液晶显示器LCD(LiquidCrystalDisplay)的不断发展，使得LCD的对比度、亮度、色域等特性也相应地提升，在绝大多数情况下，现有的LCD已能满足人们对信息显示的需求。
但是，在室外强光环境下，LCD的显示特性会因环境光线的影响变差，导致用户很难看得清屏幕的内容。然而生活中常用的设备，比如手机、手表、其他穿戴设备、以及户外设备设施等，不可避免地会在室外强光环境下使用。当LCD为暗态时，LCD具有极低的穿透率，此时背光被LCD阻挡，同时，环境光也无法穿透面板到达反射膜片，因而不会对显示效果造成影响。
但是当LCD为亮态时，背光可以透过LCD到达人眼，同时亮度较高的环境光也可透过面板到达反射膜片，再经反射进入人眼。可见，当环境光线较强时，则会影响LCD原本的显示效果，使用户很难看得清屏幕的内容，导致显示效果较差。
因此，有必要提供一种液晶显示面板及装置，以解决现有技术所存在的问题。
【发明内容】
本发明的目的在于提供一种液晶显示面板及装置，以解决现有技术的液晶显示面板及装置，在室外强光环境下使用时，显示效果较差的技术问题。
为解决上述技术问题，本发明构造了一种液晶显示面板，包括：
第一基板，包括：
第一衬底；
上偏光片，位于所述第一衬底上；
液晶层，位于所述第一基板和第二基板之间；
所述第二基板，与所述第一基板相对设置，所述第二基板包括：
第二衬底；
下偏光片，位于所述第二衬底的下方；
波片，位于所述下偏光片的下方；所述波片用于降低反射膜片对环境光的反射。
在本发明的所述液晶显示面板中，所述波片为四分之一波片或二分之一波片，或者四分之一波片和二分之一波片的组合。
在本发明的所述液晶显示面板中，所述下偏光片的吸收轴方向与所述波片的快轴方向之间的夹角为45度或135度。
在本发明的所述液晶显示面板中，所述第一基板为彩膜基板、所述第二基板为阵列基板。
在本发明的所述液晶显示面板中，所述上偏光片和所述下偏光片的材料为聚乙烯醇。
本发明还提供一种液晶显示装置，其包括：
背光模块，其包括反射膜片；以及
液晶显示面板，其包括：
第一基板，包括：
第一衬底；
上偏光片，位于所述第一衬底上；
液晶层，位于所述第一基板和第二基板之间；
所述第二基板，与所述第一基板相对设置，所述第二基板包括：
第二衬底；
下偏光片，位于所述第二衬底的下方；
波片，位于所述下偏光片的下方；所述波片用于降低所述反射膜片对环境光的反射。
在本发明的液晶显示装置中，所述波片为四分之一波片或二分之一波片，或者四分之一波片和二分之一波片的组合。
在本发明的液晶显示装置中，所述下偏光片的吸收轴方向与所述波片的快轴方向之间的夹角为45度或135度。
在本发明的液晶显示装置中，所述第一基板为彩膜基板、所述第二基板为阵列基板。
在本发明的液晶显示装置中，所述上偏光片和所述下偏光片的材料为聚乙烯醇。
本发明的液晶显示面板及装置，通过在现有面板的下偏光片下方增加波片，从而防止环境光进入面板被反射膜片反射，特别是在室外强光环境下使用时，提高了显示效果。
【附图说明】
图1为本发明的液晶显示面板的结构示意图；
图2为本发明的液晶显示面板的光路原理示意图。
【具体实施方式】
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图1，图1为本发明的液晶显示面板的结构示意图；
如图1所示，本发明的液晶显示面板，包括第一基板10和第二基板20、液晶层30；第一基板10包括第一衬底11和位于所述第一衬底上的上偏光片12；液晶层30位于第一基板10和第二基板20之间；所述第二基板20与所述第一基板10相对设置；
所述第二基板20包括第二衬底21、下偏光片22、以及波片23；所述下偏光片22位于所述第二衬底21的下方；所述波片23位于所述下偏光片22的下方，所述波片23用于降低反射膜片对环境光的反射。
如图2所示，当环境光从下偏光片22入射到波片23时，波片23使环境光形成圆偏光a，经反射膜片40反射后呈逆方向圆偏光b，圆偏光b再经波片23后，变成线偏光c，但是由于线偏光c的角度与下偏光片22的吸收轴垂直，因此经过波片23处理后的线偏光不能再透过下偏光片进入人眼。从而消除了外界环境光较强时，对显示面板的显示效果造成的影响，提高了显示效果。
此外，由于环境光进入到背光模块，还可以将环境光作为背光使用，降低了背光的功耗，且提高了环境光的利用率。
优选地，所述波片23为四分之一波片或二分之一波片，或者四分之一波片和二分之一波片的组合。
为了更好地防止环境光进入面板被反射膜片反射进入人眼，所述下偏光片22的吸收轴方向与所述波片23的快轴方向之间的夹角可以为45度或135度，由于角度太大或者太小，不能使得经过反射膜片处理后的全部线偏光的角度与下偏光片的吸收轴的角度为90度；因此当上述夹角满足上述要求时，能更好地防止环境光进入面板被反射膜片反射进入人眼。
所述第一基板10可以为彩膜基板、所述第二基板20可以为阵列基板。当第二基板20为阵列基板时，还可包括多条数据线和多条扫描线，以及由所述数据线和所述扫描线限定的多个像素单元。当第一基板10为彩膜基板时，还可包括黑色矩阵层和色阻层、以及透明导电层。
优选地，所述上偏光片12和所述下偏光片22的材料为聚乙烯醇。
本发明的液晶显示面板，由于在下偏光片下方设置波片，从而在室外强光环境下使用时，防止环境光进入面板被反射膜片反射，从而提高了显示效果。
本发明还提供一种液晶显示装置，其包括背光模组和液晶显示面板，所述背光模组包括反射膜片，如图1所示，液晶显示面板包括第一基板10和第二基板20、液晶层30；第一基板10包括第一衬底11和位于所述第一衬底上的上偏光片12；液晶层30位于第一基板10和第二基板20之间；所述第二基板20与所述第一基板10相对设置；
所述第二基板20包括第二衬底21、下偏光片22、以及波片23；所述下偏光片22位于所述第二衬底21的下方；所述波片23位于所述下偏光片22的下方，所述波片23用于降低反射膜片对环境光的反射。
如图2所示，当环境光从下偏光片22入射到波片23时，波片23使环境光形成圆偏光a，经反射膜片40反射后呈逆方向圆偏光b，圆偏光b再经波片23后，变成线偏光c，但是由于线偏光c的角度与下偏光片22的吸收轴垂直，因此经过波片23处理后的线偏光不能再透过下偏光片进入人眼。从而消除了外界环境光较强时，对显示面板的显示效果造成的影响，提高了显示效果。
此外，由于环境光进入到背光模块，还可以将环境光作为背光使用，降低了背光的功耗，且提高了环境光的利用率。
优选地，所述波片23为四分之一波片或二分之一波片，或者四分之一波片和二分之一波片的组合。
为了更好地防止环境光进入面板被反射膜片反射进入人眼，所述下偏光片22的吸收轴方向与所述波片23的快轴方向之间的夹角可以为45度或135度，由于角度太大或者太小，不能使得经过反射膜片处理后的全部线偏光的角度与下偏光片的吸收轴的角度为90度；因此当上述夹角满足上述要求时，能更好地防止环境光进入面板被反射膜片反射进入人眼。
所述第一基板10可以为彩膜基板、所述第二基板20可以为阵列基板。当第二基板20为阵列基板时，还可包括多条数据线和多条扫描线，以及由所述数据线和所述扫描线限定的多个像素单元。当第一基板10为彩膜基板时，还可包括黑色矩阵层和色阻层、以及透明导电层。
优选地，所述上偏光片12和所述下偏光片22的材料为聚乙烯醇。
本发明的液晶显示装置，由于在下偏光片下方设置波片，从而在室外强光环境下使用时，防止环境光进入面板被反射膜片进行反射，从而提高了显示效果。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
