技术领域
本申请属于显示面板技术领域，具体涉及一种显示面板和显示设备。
背景技术
相关技术中，立体(3D)显示一般采用偏光式3D显示，将显示画面划分为相互平行的多行，在上下相邻的两行中，一行显示右眼画面，另一行显示左眼画面，从而实现立体显示效果。
而这种立体显示方法仅适用于标准RGB排列的液晶显示面板，对于其他排列方式的液晶显示面板并不适用。
因此，如何对不同排列方式的液晶显示面板上实现立体显示，是亟待解决的技术问题。
发明内容
本申请旨在提供一种显示面板和显示设备，能够实现在各种不同排列方式的显示面板上实现立体显示的效果。
第一方面，本申请实施例提出了一种显示面板，包括：
显示层，显示层设置有多个发光单元；
偏振层，设置于显示层的一侧，偏振层设置有多个偏振单元，偏振单元的数量与发光单元的数量相同；
在垂直于显示层的方向上，每个偏振单元均覆盖一个发光单元。
第二方面，本申请实施例提出一种显示设备，包括如第一方面提出的 显示面板。
在本申请实施例中，显示层可以是任意像素排列方式的液晶显示面板，根据显示层的液晶排列方式，将显示层上的像素点划分为多个发光单元，并在设置于显示层一侧的偏振层上，划分与每个发光单元一一对应的偏振单元，并在垂直于显示层的方向上，使每个放光单元的发光区域，均被一个偏振单元所覆盖。
其中，相邻的偏振单元可分别根据不同的偏振方式，对其所覆盖的发光单元发出的光线进行偏振，进而区分左眼图像和右眼图像，从而实现立体显示效果。
本申请实施例通过根据显示层上像素点的分布特征，将显示层划分为多个发光区域，其中多个发光区域排列分布在显示层上，并设置偏振层上的每个偏振单元均与一个发光区域相对应，因此无论显示层上是何种像素排列方式，如标准RGB排列的液晶显面板(Liquid Crystal Display，LCD)，或钻石排列的主动矩阵有机发光二极管(Active-matrix organic light-emitting diode，AMOLED)显示面板，又或是RGB delta排列的微缩化发光二极管显示面板(micro-LED display)等，均能够实现立体显示，从而实现了在各种不同排列方式的显示面板上实现立体显示的效果。

下面结合图1至图7描述根据本申请实施例的显示面板和显示设备。
在本申请的一些实施例中，图1示出了根据本申请实施例的显示面板100的结构示意图，具体地，显示面板100包括：
显示层102，显示层102设置有多个发光单元1022；
偏振层104，设置于显示层102的一侧，偏振层104设置有多个偏振单元1042，偏振单元1042的数量与发光单元1022的数量相同；
在垂直于显示层102的方向上，每个偏振单元1042均覆盖一个发光单元1022。
在本申请实施例中，显示层102可以是任意像素排列方式的液晶显示面板100，根据显示层102的液晶排列方式，将显示层102上的像素点划分为多个发光单元1022，并在设置于显示层102一侧的偏振层104上，划分与每个发光单元1022一一对应的偏振单元1042，并在垂直于显示层102的方向上，使每个放光单元的发光区域，均被一个偏振单元1042所覆盖。
其中，相邻的偏振单元1042可分别根据不同的偏振方式，对其所覆盖的发光单元1022发出的光线进行偏振，进而区分左眼图像和右眼图像，从而实现立体显示效果。
本申请实施例通过根据显示层102上像素点的分布特征，将显示层102划分为多个发光区域，其中多个发光区域排列分布在显示层102上，并设置偏振层104上的每个偏振单元1042均与一个发光区域相对应，因此无论显示层102上是何种像素排列方式，如标准RGB排列的液晶显面板，或钻石排列的主动矩阵有机发光二极管显示面板100，又或是RGB delta排列的微缩化发光二极管显示面板100等，均能够实现立体显示，从而实现了在各种不同排列方式的显示面板100上实现立体显示的效果。
在本申请的一些实施例中，偏振单元1042呈阵列式分布，偏振单元1042包括第一偏振单元和第二偏振单元，在偏振单元1042的排列方向上，第一偏振单元和第二偏振单元交替分布。
在本申请实施例中，偏振单元1042呈阵列式分布，即按照一定的规律分布，且偏振单元1042的分布方式，与发光单元1022的分布方式相同。 具体地，偏振单元1042包括第一偏振单元和第二偏振单元，其中，第一偏振单元的偏振方式，与第二偏振单元的偏振方式不同，因此，被第一偏振单元覆盖的发光单元1022，能够发光并构成“左眼图像”。被第二偏振单元覆盖的发光单元1022，能够发光并构成“右眼图像”，因此该显示面板100所显示的图像，在被特定的方式观看时，能够呈现出“立体”效果。
其中，在偏振单元1042的排列方向上，第一偏振单元和第二偏振单元交替分布，也就是说，与第一偏振单元相邻的偏振单元1042均为第二偏振单元，与第二偏振单元相邻的偏振单元1042均为第一偏振单元，也就是说第一偏振单元和第二偏振单元交错设置。这里的相邻，根据偏振单元1042的形状，指的是具有公共边的两个偏振单元1042。
举例来说，假设偏振单元1042为矩形偏振单元1042，则与当前第一偏振单元相邻的第二偏振单元的数量为4个，分别为长边相邻的2个第二偏振单元和宽边相邻的2个。如果偏振单元1042为六边形变阵单元，则与当前第一偏振单元相邻的第二偏振单元的数量为6个，六边形的第一偏振单元的每条边均与一个第二偏振单元相邻。
通过使相邻的偏振单元1042为不同偏振方式的偏振单元1042，实现了将左眼影响和右眼影响相分离，同时使左眼影响和右眼影响均匀分布，能够提高立体显示的显示效果。
在本申请的一些实施例中，第一偏振单元和第二偏振单元均为相位延迟偏振单元1042；第一偏振单元为λ/2相位延迟偏振单元1042，其中λ为发光单元1022所发出的光的波长；第二偏振单元为零相位延迟偏振单元1042。
在本申请实施例中，第一偏振单元和第二偏振单元设置为相位延迟偏振单元1042。具体地，第一偏振单元可以设置为λ/2相位延迟偏振单元1042，第二偏振单元可以设置为零相位延迟偏振单元1042。
举例来说，假设第一偏振单元覆盖的发光单元1022对应左眼图像，第二偏振单元覆盖的发光单元1022对应右眼图像，显示面板100垂直于水平面设置，即显示面板100的厚度方向与水平方向平行，此时通过第一偏振单元能够产生水平线性偏振光影像，通过第二偏振单元能够产生垂直线性 偏振光影响，因此左眼影像和右眼影像因通过不同相位延迟单元形成不同方向的偏振，即形成不同方向的偏极化的光，使得观察者通过对应的手段观看图像时，左眼和右眼分别智能观察到特定方向偏极化的光，最终实现了立体显示效果。
在本申请的一些实施例中，图2示出了根据本申请实施例的偏振层104的结构示意图之一，如图2所示，第一偏振单元和第二偏振单元均为线性偏振单元1042；第一偏振单元的偏振方向为第一方向；第二偏振单元的偏振方向为第二方向，第一方向垂直于第二方向。
在本申请实施例中，第一偏振单元和第二偏振单元设置为线性偏振单元1042。具体地，第一偏振单元的偏振方向设置为第一方向，第二偏振单元的偏振方向设置为第二方向。
举例来说，假设第一偏振单元覆盖的发光单元1022对应左眼图像，第二偏振单元覆盖的发光单元1022对应右眼图像，显示面板100垂直于水平面设置，即显示面板100的厚度方向与水平方向平行。
此时通过第一偏振单元将左眼图像的光向第一方向偏极化，假设此处第一方向为水平方向。通过第二偏振单元将右眼图像的光向第二方向偏极化，此处第二方向对应为垂直方向，因此左眼影像和右眼影像形成不同方向的偏极化的光，使得观察者通过对应的手段观看图像时，左眼和右眼分别智能观察到特定方向偏极化的光，最终实现了立体显示效果。
在本申请的一些实施例中，图3示出了根据本申请实施例的偏振层104的结构示意图之二，如图3所示，第一偏振单元和第二偏振单元均为圆偏振单元1042；第一偏振单元的偏振方向为顺时针旋转偏振；第二偏振单元的偏振方向为逆时针旋转偏振。
在本申请实施例中，第一偏振单元和第二偏振单元设置为圆偏振单元1042。具体地，第一偏振单元的偏振方向设置为顺时针旋转偏振，第二偏振单元的偏振方向设置为逆时针旋转偏振。
举例来说，假设第一偏振单元覆盖的发光单元1022对应左眼图像，第二偏振单元覆盖的发光单元1022对应右眼图像，显示面板100垂直于水平面设置，即显示面板100的厚度方向与水平方向平行。
此时通过第一偏振单元将左眼图像的光顺时针偏振，即右旋偏振，通过第二偏振单元将右眼图像的光逆时针偏振，即左旋偏振，因此左眼影像和右眼影像形成不同方向的偏极化的光，使得观察者通过对应的手段观看图像时，左眼和右眼分别智能观察到特定方向偏极化的光，最终实现了立体显示效果。
在本申请的一些实施例中，偏振层104的面积大于显示层102的面积，且偏振层104覆盖显示层102的全部发光区域。
在本申请实施例中，偏振层104的面积大于显示层102的面积，具体地，由于一般的液晶显示面板100，需要通过切割的方式将液晶面板加工成所需要的形状，如矩形。而在形状的边缘部分，对于非标准RGB排列的面板，由于其像素排列非“整齐”排列，因此切割的边缘和角落部分可能存在非完整的发光单元1022。而这些非完整的发光单元1022，其中的像素也会发光，因此将偏振层104的面积设置为大于显示层102的面积，并使偏振层104覆盖显示层102的全部发光面积，能够保证边缘、角落处的非完整发光单元1022或像素也能按照相同的规则被偏振，从而能够提高立体显示的显示效果。
在本申请的一些实施例中，显示层102设置有多个子像素，每个发光单元1022中的子像素的种类和子像素的数量均相同；以及偏振单元1042的排列方式与发光单元1022的排列方式相同。
在本申请实施例中，显示层102设置有多个子像素，其中每个子像素均能发出一种颜色的光。每个发光单元1022中的子像素的种类，和子像素的数量均相同，因此通过相同的驱动方式，能够保证每个发光单元1022在发出相同颜色的光时，最终发出光的颜色和亮度基本相同，从而保证立体显示效果，避免出现偏色或亮度不均匀的情况。
同时，偏振单元1042的排列方式与发光单元1022的排列方式相同，因此在生产制造显示面板100时，在将偏振层104贴合在显示层102的一侧后，每个偏振单元1042会自动“对齐”一个发光单元1022，从而保证每个发光单元1022都被对应的偏振单元1042覆盖，从而提高立体显示效果。
具体举例来说，对于标准RGB排列的LCD显示面板100，其上分布设置有R(Red，红)像素、G(Green，绿)像素和B(Blue，蓝)像素。一个R像素、一个G像素和一个B像素能够形成为一个发光单元1022，该发光单元1022通过调节R像素、G像素和B像素的亮度，来实现发出不同颜色的光。
继续以标准RGB排列的LCD显示面板100为例，宏观来看，每个发光单元1022为一个“像素点”，多个像素点组合最终构成显示画面。其中，每个像素点均被一个偏振单元1042所覆盖，因此相邻的两个像素分别对应左眼画面的像素和右眼画面的像素，使得左眼画面和右眼画面分布更加均匀，有效地提高了立体显示效果。
在本申请的一些实施例中，图4示出了根据本申请实施例的显示层102的结构示意图之一，图5示出了根据本申请实施例的显示层102的结构示意图之二，如图4所示，发光单元1022为矩形发光单元1022，偏振单元1042为矩形偏振单元1042；或
如图5所示，发光单元1022为六边形发光单元1022，偏振单元1042为六边形偏振单元1042。
在本申请实施例中，发光单元1022的具体形状根据显示层102的像素排列方式进行设置，偏振单元1042的具体形状则与发光单元1022的形状相匹配。具体地，以图4为例，图4中的显示层102的像素排列方式为“钻石排列”，如图4所示，发光单元1022的形状为矩形，分别以两个蓝像素和两个红像素为对角，确定一个矩形区域，绿像素位于矩形区域内。
以图5为例，图5中的显示层102的像素排列方式为RGB delta排列，如图5所示，发光单元1022的形状为六边形，六边形的六个定点分别为3个红像素和3个蓝像素，确定为一个六边形区域，绿像素位于六边形区域内。
在本申请的一些实施例中，如图4和图5所示，子像素包括红像素、蓝像素和绿像素，每个发光单元1022中均包括红像素区域、蓝像素区域和绿像素区域：
其中，红像素区域包括一个红像素的至少部分区域；
蓝像素区域包括一个蓝像素的至少部分区域；
绿像素区域包括一个绿像素的至少部分区域。
在本申请实施例中，子像素包括红像素、蓝像素和绿像素，红像素能够发出红光，或显示层102的背光通过红像素后，形成红光。同理，蓝像素能够发出蓝光，或显示层102的背光通过蓝像素后，形成蓝光；绿像素能够发出滤光，或显示层102的背光通过绿像素后，形成绿光。
在一些实施方式中，子像素还可以包括白像素，白像素发出白光，或者使背光直接通过，从而提高显示层102的最大显示亮度。
其中，每个发光单元1022中，具有相同种类的发光子像素，如每个发光单元1022中均包括红像素、绿像素和蓝像素。发光单元1022中，每种颜色的像素的数量也相同。如图4所示，图4示出的显示层102中，每个矩形发光单元1022中，均包括两个四分之一的蓝像素，两个四分之一的红像素，和一个完整的绿像素。
如图5所示，图5示出的显示层102中，每个红像素均被分成了3个部分，每个六边形发光单元1022中，均包括来自3个不同红像素的3个不同部分。每个蓝像素也被分成了3个部分，每个六边形发光单元1022中，均包括来自3个不同蓝像素的3个不同部分。同时，每个六边形发光单元1022中，还包括一个完整的绿像素。
在本申请的一些实施例中，图6示出了根据本申请实施例的显示设备的结构框图，如图6所示，显示设备600包括：如上述任一实施例中提供的显示面板100。
在本申请实施例中，显示设备包括如上述任一实施例中提供的显示面板100，显示面板100包括显示层和偏振层，显示层可以是任意像素排列方式的液晶显示面板，根据显示层的液晶排列方式，将显示层上的像素点划分为多个发光单元，并在设置于显示层一侧的偏振层上，划分与每个发光单元一一对应的偏振单元，并在发光单元的发光方向上，使每个放光单元的发光区域，均被一个偏振单元所覆盖。
其中，相邻的偏振单元可分别根据不同的偏振方式，对其所覆盖的发光单元发出的光线进行偏振，进而区分左眼图像和右眼图像。偏振镜片与 显示面板向匹配，观察者佩戴设置有偏振镜片的偏振眼镜后，左眼仅能看到左眼图像，右眼仅能看到右眼图像，从而实现立体显示效果。
本申请实施例通过根据显示层上像素点的分布特征，将显示层划分为多个发光区域，其中多个发光区域排列分布在显示层上，并设置偏振层上的每个偏振单元均与一个发光区域相对应，因此无论显示层上是何种像素排列方式，如标准RGB排列的液晶显面板，或钻石排列的主动矩阵有机发光二极管显示面板，又或是RGB delta排列的微缩化发光二极管显示面板等，均能够实现立体显示，从而实现了在各种不同排列方式的显示面板上实现立体显示的效果。
在本申请的一些实施例中，图7示出了根据本申请实施例的眼镜设备的结构框图，如图7所示，眼镜设备700包括：偏振镜片702，偏振镜片702与如上述任一实施例中提供的显示面板100相匹配。
在本申请实施例中，偏振镜片702包括第一偏振镜片和第二偏振镜片；显示面板包括偏振层，偏振层包括第一偏振单元和第二偏振单元；其中，第一偏振镜片的偏振方向与第一偏振单元的偏振方向相同，第二偏振镜片的偏振方向与第二偏振单元的偏振方向相同。
在本申请实施例中，偏振单元包括第一偏振单元和第二偏振单元，与之相对应的，偏振镜片也包括第一偏振镜片和第二偏振镜片。其中第一偏振镜片与第一偏振单元相匹配，第二偏振镜片与第二偏振单元相匹配。
具体地，第一偏振镜片的偏振方向与第一偏振单元的偏振方向相同，举例来说，假设第一偏振镜片为左眼镜片，第一偏振单元覆盖的发光单元显示左眼图像。如果第一偏振单元为λ/2相位延迟偏振单元，则第一偏振镜片的相位延迟同为λ/2。如果第一偏振单元的偏振方向为第一方向，则第一偏振镜片的偏振方向也同为第一方向。如果第一偏振单元的偏振方向为顺时针旋转偏振，则第一偏振镜片的偏振方向也为顺时针旋转偏振。
同理的，如果第二偏振单元为λ/2相位延迟偏振单元，则第二偏振镜片的相位延迟同为λ/2。如果第二偏振单元的偏振方向为第二方向，则第二偏振镜片的偏振方向也同为第二方向。如果第二偏振单元的偏振方向为顺时针旋转偏振，则第二偏振镜片的偏振方向也为顺时针旋转偏振。
因此，左眼镜片仅允许左眼图像的光通过，即左眼镜片会“滤除”右眼图像的光。右眼镜片仅允许右眼图像的光通过，即右眼镜片会“滤除”左眼图像的光。所以观察者能够在显示面上的图像中看出“立体”效果。
本申请实施例通过根据显示层上像素点的分布特征，将显示层划分为多个发光区域，其中多个发光区域排列分布在显示层上，并设置偏振层上的每个偏振单元均与一个发光区域相对应，因此无论显示层上是何种像素排列方式，如标准RGB排列的液晶显面板，或钻石排列的主动矩阵有机发光二极管显示面板，又或是RGB delta排列的微缩化发光二极管显示面板等，均能够实现立体显示，从而实现了在各种不同排列方式的显示面板上实现立体显示的效果，且通过使相邻的偏振单元为不同偏振方式的偏振单元，实现了将左眼影响和右眼影响相分离，同时使左眼影响和右眼影响均匀分布，能够提高立体显示的显示效果。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
