Abstract

一种显示面板(10)，包括：第一偏光片(12)，设置于显示面板本体(11)的非显示侧；第一波片(13)，设置于显示面板本体(11)的显示侧；其中，第一波片(13)为(1/2N+1/4)波片，N为正整数，显示面板(10)用于与包括第二偏光片(22)、第二波片(21)的眼镜(20)配合呈现图像。由于眼镜(20)上的第二波片(21)与显示面板(10)上的第一波片(13)不需要进行角度搭配就能呈现良好的图像，使得用户使用眼镜(20)观看显示面板(10)时，即便眼镜(20)发生歪斜或偏移，也能观看到良好的图像，从而确保显示面板(10)的暗态和低灰阶亮度保持很低的状态，避免对比度降低，同时由于第二偏光片(22)设置于眼镜(20)上，只有显示面板(10)的使用者佩戴眼镜(20)才能看清楚图像，从而起到了防窥作用。

具体地，显示面板10用于与包括第二偏光片22、第二波片21的眼镜20配合呈现图像，即显示面板10用于与眼镜20搭配来显示或观看图像，用户使用眼镜20可以观看到显示面板10的显示图像而获取需要的信息，而他人没有佩戴对应的眼镜20就不能看到显示面板10显示的正确图像信息，从而实现了防窥显示。
具体地，显示侧是指显示面板10或显示面板本体11显示图像信息的一侧，即用户观看显示面板10的一侧，例如显示侧是指图1中第一波片13远离显示面板本体11的一侧。
具体地，非显示侧是指远离显示面板10或显示面板本体11显示图像信息的一侧，即远离用户观看显示面板10的一侧，例如非显示侧是指图1中第一偏光片12远离显示面板本体11的一侧。
具体地，显示面板10可以为液晶显示面板，显示面板本体11可以为液晶显示面板本体，液晶显示面板本体可以包括彩膜基板、阵列基板、夹设在彩膜基板和阵列基板之间的液晶层。
具体地，显示面板10包括显示面板本体11、第一偏光片12、第一波片13，第一偏光片12设置于显示面板本体11的非显示侧；第一波片13设置于显示面板本体11的显示侧，即显示面板本体11夹设在第一偏光片12和第一波片13之间，且第一波片远离显示面板本体11的一侧为显示侧。
具体地，第一波片13为(1/2N+1/4)波片，N为正整数，第一波片13为四分之三波片，第一波片13为与四分之三波片具有相同功能的波片，在后续详细介绍。
在一些实施例中，第一波片13直接贴附于显示面板本体11的显示侧的表面上，第一波片13远离显示面板本体11的一侧不设置另一偏光片。
具体地，显示面板10仅包括第一偏光片12和第一波片13，在显示面板本体11的显示侧不包括第一波片13之外的偏光片。
在本实施例中，通过在显示面板本体的显示侧设置第一波片13，显示面板10用于与包括第二偏光片22、第二波片21的眼镜20配合呈现图像，在与显示面板10配合的眼镜20中，显示面板10发出的光线从第一波片13出射后转变成圆偏振光，此圆偏振光通过眼镜20上的第二波片21转变成线偏振光，此线偏振光可以通过第二偏光片22而呈现图像，由于眼镜20上的第二波片21与显示面板10上的第一波片13不需要进行角度搭配就能呈现良好的图像，使得使用眼镜20观看显示面板10时，即便眼镜20发生歪斜或偏移，也能观看到良好的图像，从而确保显示面板10的暗态和低灰阶亮度保持很低的状态，避免对比度降低，避免了显示效果严重降低的发生，同时由于第二偏光片22设置于眼镜20上，只有显示面板10的使用者佩戴眼镜20才能看清楚图像，从而起到了防窥作用，可以保护用户的隐私等信息。眼镜20的结构和功能在后续实施例详细介绍。
实施例二
请参阅图2至图3，本实施例提供了一种显示系统100，显示系统100包 括显示面板10和眼镜20，实施例一中的任一项显示面板10可以用于本实施例的显示系统100中，可以实现防窥显示，且具有低的暗态亮度和低的低灰阶亮度、高对比度、高图像质量的效果，然而，实施例一中的任一项的显示面板10并不是对本实施例中的显示系统100所包括的显示面板10的限定。
本实施例提供了一种显示系统100，显示系统100包括显示面板10和眼镜20；显示面板10包括显示面板本体11、设置于显示面板本体11的非显示侧的第一偏光片12、设置于显示面板本体11的显示侧的第一波片13；其中，显示侧与非显示侧相对设置；眼镜20包括第二偏光片22、第二波片21，第二偏光片22包括偏光层221，第二波片21设置于偏光层221的远眼侧；其中，眼镜20用于呈现显示面板10的显示图像。
具体地，显示系统100包括显示面板10和眼镜20，眼镜20用于呈现或观看显示面板10的显示图像。
具体地，近眼侧是指：用户佩戴眼镜20观看显示面板10的显示图像时，靠近用户的眼睛的一侧，或是远离显示面板10的一侧。
具体地，远眼侧是指：用户佩戴眼镜20观看显示面板10的显示图像时，远离用户的眼睛的一侧，或是靠近显示面板10的一侧。
具体地，显示面板10包括显示面板本体11、设置于显示面板本体11的非显示侧的第一偏光片12、设置于显示面板本体11的显示侧的第一波片13,即显示面板本体11夹设在第一偏光片12和第一波片13之间。
具体地，眼镜20包括第二偏光片22、第二波片21，第二偏光片22包括偏光层221，第二波片21设置于偏光层221的远眼侧，即用户佩戴眼镜20观看显示面板10的显示图像时，第二波片21相比于偏光层221更靠近显示面板10。
具体地，由于第二偏光片22设置于眼镜20上，只有显示面板10的使用者佩戴眼镜20才能看清楚图像，而傍观者无法观看到显示系统呈现的显示图像，从而起到了防窥作用。
在一些实施例中，第一波片13和第二波片21分别为(1/2N+1/4)波片和(1/2M+1/4)波片，N和M均为正整数。
具体地，第一波片13为(1/2N+1/4)波片，第二波片21为(1/2M+1/4)波片， N和M均为正整数。
具体地，第一波片13和第二波片21均为四分之三波片，第一波片13和第二波片21均与四分之三波片具有相同功能的波片。
具体地，第一波片13和第二波片21可以具有不同的厚度，N和M的数值可以不相同。
具体地，第一波片13和第二波片21相互配合，使得光线或自然光依次经过第一偏光片12、显示面板本体11、第一波片13和第二波片21后，能够正常通过第二偏光片22或被第二偏光片22正常阻挡，即便眼镜20发生歪斜或偏移，也能观看到良好的图像，可以使得用户使用眼镜20观看显示面板10时，确保显示面板10的暗态和低灰阶保持很低亮度状态，避免对比度降低，避免了显示效果严重降低的发生，同时由于第二偏光片22设置于眼镜20上，只有显示面板10的使用者佩戴眼镜20才能看清楚图像，从而起到了防窥作用。
在一些实施例中，第一偏光片12的吸收轴与第一波片13的光轴的锐角夹角大于或等于40度，且小于或等于50度。
具体地，第一偏光片12的吸收轴与第一波片13的光轴搭配，第一波片13可以将依次通过第一偏光片12和显示面板本体11的线偏振光转变为圆偏振光，第一偏光片12的吸收轴与第一波片13的光轴的搭配角度为：锐角夹角大于或等于40度，且小于或等于50度。
具体地，第一偏光片12的吸收轴与第一波片13的光轴的锐角夹角大于或等于40度，且小于或等于50度，即第一偏光片12的吸收轴与第一波片13的光轴的夹角为40度至50度范围(包括40度和50度)，或第一偏光片12的吸收轴与第一波片13的光轴的夹角为130度至140度范围(包括130度和140度)。
进一步地，优选的，第一偏光片12的吸收轴与第一波片13的光轴的锐角夹角等于45度，即第一偏光片12的吸收轴与第一波片13的光轴的夹角等于45度或135度，第一波片13可以更好的转变光线。
在一些实施例中，第二偏光片22的吸收轴与第二波片21的光轴的锐角夹角大于或等于40度，且小于或等于50度。
具体地，第二偏光片22的吸收轴与第二波片21的光轴搭配，第二偏光片 22的偏光层可以透过依次经过显示面板10和第二波片21的偏振光，第二偏光片22的吸收轴与第二波片21的光轴的搭配角度为：锐角夹角大于或等于40度，且小于或等于50度。
具体地，第二偏光片22的吸收轴与第二波片21的光轴的锐角夹角大于或等于40度，且小于或等于50度，即第二偏光片22的吸收轴与第二波片21的光轴的夹角为40度至50度范围(包括40度和50度)，或第二偏光片22的吸收轴与第二波片21的光轴的夹角为130度至140度范围(包括130度和140度)。
进一步地，优选的，第二偏光片22的吸收轴与第二波片21的光轴的锐角夹角等于45度，即第二偏光片22的吸收轴与第二波片21的光轴的夹角等于45度或135度，第二波片21可以更好的转变光线。
具体地，需要说明的是，由于显示面板本体11的显示侧设置有第一波片13，可以将通过显示面板本体11的光线转变为圆偏振光，眼镜20上的第二波片21再将通过显示面板10的圆偏振光转变为线偏振光，此线偏振光再透过第二偏光片22的偏振层达到人眼或呈现图像，因此用户只要佩戴眼镜20，眼镜20可以随意旋转或任意角度佩戴，均可以看到或呈现显示面板10上的图像，而未佩戴眼镜的其他人不能看到显示面板10上的图像。
进一步地，在眼镜20与显示面板10正对的情况下，第一偏光片12的吸收轴和第二偏光片22的吸收轴相互垂直，即用户佩戴眼镜20观看显示面板10的显示图像，第一偏光片12的吸收轴和第二偏光片22的吸收轴刚好相互垂直时，用户通常可以处于此种观看状态。
具体地，如图2所示，示意了眼镜20与显示面板10正对的情况下。
具体地，眼镜20与显示面板10正对的情况是指第一偏光片12的吸收轴和第二偏光片22的吸收轴相互垂直。
具体地，在眼镜20与显示面板10正对情况下，第一偏光片12和第二偏光片22的吸收轴相互垂直，用户通常可以处于此种观看状态，以眼镜20与显示面板10正对情况描述了第一偏光片12、第一波片13、第二偏光片22、第二波片21中的角度设置关系。
具体地，进一步的，在一些实施例中，显示面板10在显示面板本体11的 显示侧不设置另一偏光片，更具体地，显示面板10仅包括第一偏光片12，不包括第一偏光片12之外的偏光片。
需要说明的是，后续实施例以优选的第一偏光片12的吸收轴与第一波片13的光轴的锐角夹角等于45度，以及优选的第二偏光片22的吸收轴与第二波片21的光轴的锐角夹角等于45度的实施情况进行说明。
在一些实施例中，在眼镜20与显示面板10正对的情况下，第一波片13的光轴和第二波片21的光轴相互垂直，第一波片13的光轴与第一偏光片12的吸收轴的锐角夹角为45度。
具体地，第一偏光片12、第一波片13、第二波片21、第二偏光片22的搭配、配合、适配关系为：第一偏光片12的吸收轴和第二偏光片22的吸收轴相互垂直，第一波片13的光轴和第二波片21的光轴相互垂直，第一波片13的光轴与第一偏光片12的吸收轴的锐角夹角为45度。
具体地，第一波片13的光轴与第一偏光片12的吸收轴的锐角夹角为45度，第一波片13的光轴与第一偏光片12的吸收轴的钝角夹角为135。
具体地，第一偏光片12、第一波片13、第二波片21、第二偏光片22的配合，使得用户观看时，显示面板10具有低的暗态亮度和低的低灰阶亮度、高对比度、高图像质量的效果，且实现了防窥功能。

具体地，如图8所示，在一些实施情况中，眼镜20包括第二偏光片22，第二偏光片22包括偏光层221和第二波片21，偏光层221和第二波片21均 位于第二偏光片22内，以便于偏光片生产企业出货，并减小眼镜20的厚度。
进一步地，在一些实施例中，第一波片13和第二波片21的材料包括环状聚烯烃(COP)、三醋酸纤维(TAC)中至少一种。
具体地，环状聚烯烃(COP)、三醋酸纤维(TAC)是良好的第一波片13和第二波片21的材料。
