Description

一种偏光式三维液晶显示器及其制作方法
【技术领域】
本发明涉及液晶显示技术领域，特别是涉及一种偏光式三维液晶显示器及其制作方法。
【背景技术】
FPR（Film-type Patterned Retarder，偏光式）是现有3D液晶显示的成像方式之一。如图1所示，FPR 3D显示系统包括液晶显示面板10、偏光片20以及偏光（Patterned Retarder）薄膜30。FPR 3D显示系统主要是通过附着在液晶显示面板10上的偏光薄膜30将3D画面分离成左眼图像41和右眼图像42，再经过偏光眼镜（图未示）将左眼图像41和右眼图像42分别送至用户的左、右眼睛。用户的左右眼接收到两组信号，再经大脑合成立体影像。
FPR 3D显示模式存在视角限制问题。如图1所示，在正常视角下，左眼图像41和右眼图像42能够正确送到观看者的左右眼。但是当观看者处于较大视角位置时会出现双眼信号相互串扰（X-talk）的现象，如本应送到右眼的右眼图像43却被左眼同时观察到了，由此会导致画面严重串扰，图像清晰度差。
通常的解决方案是增加液晶显示面板10中左眼像素L和右眼像素R间黑色矩阵（BM，Black Matrix）11中单个黑色带的宽度，以减小双眼信号串扰的可能性。但是黑色矩阵11中单个黑色带的宽度过大会导致穿透率大幅降低，而宽度过小又达不到改善大视角双眼信号串扰的目的。
【发明内容】
本发明主要解决的技术问题是提供一种偏光式三维液晶显示器及其制作方法，能够减少三维显示模式下的双眼信号串扰现象，增大观看视角，同时提高穿透率和开口率。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种偏光式三维液晶显示器，包括液晶显示面板、偏光片以及偏光薄膜；液晶显示面板包括间隔设置的第一基板和第二基板；其中，偏光片和偏光薄膜依次设置在第二基板背对第一基板的一侧，第二基板在邻近第一基板的一侧设置有黑色矩阵，偏光薄膜邻近偏光片的表面设置有遮光结构，遮光结构对应黑色矩阵至少一部分设置，并且遮光结构的中心位置与黑色矩阵的中心位置相对应。

其中，遮光结构是与黑色矩阵对应的遮光矩阵。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种偏光式三维液晶显示器，包括液晶显示面板、偏光片以及偏光薄膜；液晶显示面板包括间隔设置的第一基板和第二基板；其中，偏光片和偏光薄膜依次设置在第二基板背对第一基板的一侧，第二基板在邻近第一基板的一侧设置有黑色矩阵，偏光薄膜邻近第二基板的一侧设置有遮光结构，遮光结构对应黑色矩阵至少一部分设置。

【附图说明】
图1是现有技术中一种FPR 3D显示系统的结构示意图；
图2是本发明偏光式三维液晶显示器的一实施方式的结构示意图；
图3是本发明偏光式三维液晶显示器的制作方法的一实施方式的流程图。
【具体实施方式】
下面将结合实施方式和附图对本发明进行详细说明。
参阅图2，在本发明偏光式三维液晶显示器的一实施方式中，偏光式三维液晶显示器包括：液晶显示面板101、偏光片102和偏光薄膜103。
液晶显示面板101包括间隔设置的第一基板1011和第二基板1012。其中，第一基板1011为阵列基板，第二基板1012为彩色滤光基板，将第一基板1011和第二基板1012贴合组装形成液晶显示面板101。第一基板1011和第二基板1012间隔设置，并且在第一基板1011和第二基板1012之间具有液晶层（图未示）。
按照三维显示的格局，液晶显示面板101还可以划分为多个对应于一个像素单元并用于显示左眼图像的左图像单元1013，以及对应于一个像素并用于显示右眼图像的右图像单元1014。通过左图像单元1013和右图像单元1014以实现液晶显示面板101的三维图像画面显示。
其中，偏光片102和偏光薄膜103依次设置在第二基板1012背对第一基板1011的一侧，可依序设置在第二基板1012外表面，当然也可以依次设置在其他结构上，只要满足偏光片102和偏光薄膜103设置在第二基板1012背对第一基板1011的一侧即可，此处不进行具体限制。
在第二基板1012邻近第一基板1011的一侧设置有黑色矩阵104。黑色矩阵104设置在第二基板1012上，其所在位置对应于左图像单元1013和右图像单元1014之间的区域。偏光薄膜103邻近第二基板1012的一侧设置有遮光结构105。本实施方式中，遮光结构105与黑色矩阵104对应设置，包括多个沿液晶显示面板101列向设置的遮光带1051，遮光带1051与黑色矩阵104的多个列向部分一一对应。可以理解为，遮光带1051与黑色矩阵104中的多个列向的黑色带一一对应。遮光带1051的中心位置与黑色矩阵104的列向部分中心位置相对应，配合黑色矩阵104以获得更好的遮光效果。
工作时，液晶显示面板101显示的三维画面所对应的光线在经过偏光薄膜103后，能够形成对应左眼图像和右眼图像的两种光线，即，偏光薄膜103将液晶显示面板101的三维画面分为垂直向偏振光和水平向偏振光两组画面，垂直向偏振光和水平向偏振光两组画面所对应的光线通过偏光眼镜（图未示）的两个偏振方向垂直的镜片后，分别得到左眼图像和右眼图像，最终观看者所看到的画面为三维画面。
在三维显示模式下，观看者处于较大视角时左右眼容易接收到错误的光线，而本实施方式的遮光带1051具有遮光效果，因此如图2所示，至少遮挡住部分将会被眼睛接收到的错误光线，与黑色矩阵104相配合能够进一步减少三维显示模式下的双眼信号串扰现象。
具体地，继续参阅图2，当观看者的视角为正向液晶显示器时，观看者能获得正常的左眼图像1061和右眼图像1062所对应的光线，此时没有发生双眼信号串扰。当观看者处于较大视角时，易发生双眼信号串扰，例如，发生串扰的右眼图像1063所对应的光线会传送观看者的左眼，使观看者观看到错误的影像。为避免这种现象，通过增加黑色矩阵104的宽度，利用黑色矩阵104遮挡发生串扰的光线，以尽可能减少信号串扰现象。而在偏光薄膜103邻近第二基板1012的表面并且与黑色矩阵104相对应的位置设置有遮光结构105，遮光结构105中的遮光带1051相对应于黑色矩阵104中列向的黑色带设置，也具有黑色矩阵104的效果。因此，在三维显示模式的大视角下，黑色矩阵104无需增加过宽的宽度，而是利用遮光带1051遮挡发生串扰的光线，如图2所示，发生串扰的右眼图像1063的部分光线被遮光带1051阻挡，从而减少了双眼信号串扰的现象。
因此，在本实施方式中，通过遮光带1051的作用，使得黑色矩阵104无需增加过宽的宽度也能够减少大视角下双眼信号串扰的现象，满足视角需求，而在相同视角规格下能够相对减小黑色矩阵104中单个黑色带的宽度，从而能够提高开口率和穿透率。遮光带1051的宽度可以根据视角需求、黑色矩阵104的宽度或者偏光薄膜103的贴附精度进行调整，在此并不做具体限制。
在本实施方式中，遮光结构105包括多个遮光带1051，遮光带1051相对应于黑色矩阵104中的多个列向部分而设置。而在另一实施方式中，遮光结构105则是与黑色矩阵104对应的遮光矩阵，形状可以与黑色矩阵104类似或相同。遮光矩阵与黑色矩阵104相配合也能够减少大视角下的双眼信号串扰现象，同时提高穿透率和开口率，具体的实现原理在此不进行一一赘述。
参阅图3，本发明偏光式三维液晶显示器的制作方法一实施方式，包括步骤：
步骤S101：分别形成第一基板和第二基板。
液晶显示面板的制作过程是制作液晶显示器的一个环节，而在液晶显示面板的制作过程中，一般分为阵列制程、组立制程和模组制程三个阶段。在前段的阵列制程中，主要是形成阵列基板，而本实施方式的第一基板即为阵列基板。在进入中段组立制程之前，如图2所示，首先形成第一基板1011和第二基板1012，其中，第一基板1011为阵列基板，第二基板1012为彩色滤光基板。
步骤S102：组装第一基板和第二基板，使第一基板和第二基板间隔设置以形成液晶显示面板。
完成步骤S102后，进入液晶显示面板的组立制程，将第一基板1011和第二基板1012进行贴合组装，组装过程中使第一基板1011和第二基板1012间隔设置，以在第一基板1011和第二基板1012之间灌入液晶（图未示），从而在第一基板1011和第二基板1012之间形成液晶分子层。其中，在将第一基板1011和第二基板1012贴合前，在第二基板1012邻近第一基板1011的一侧形成黑色矩阵104。黑色矩阵104的至少一部分所在的位置与液晶显示面板101的左图像单元1013和右图像单元1014之间的区域相对应。
在后段模组制程过程，主要是将组立制程形成的组合玻璃基板与背光板、电路等多种零件组装起来以形成液晶显示面板101。
步骤S103：在第二基板背对第一基板的一侧依次形成偏光片和偏光薄膜。
在第二基板1012背对第一基板1011的一侧依次形成偏光片102和偏光薄膜103，使得在三维显示模式下能够形成左眼图像和右眼图像所对应的光线，以达到三维的显示效果。液晶显示面板101的显示面为第二基板1012背对第一基板1011的一面，因此偏光片102和偏光薄膜103依序形成于第二基板1012的外表面上，当然也可以依序形成于第二基板1012背对第一基板1011一侧的其他结构上。其中，在形成偏光薄膜103时或之前，在偏光薄膜103邻近第二基板1012的一侧形成遮光结构105，并使遮光结构105对应黑色矩阵104至少部分设置。
本实施方式中，遮光结构105包括多个遮光带1051，遮光带1051沿液晶显示面板100列向设置，并与黑色矩阵104的多个列向部分一一对应。当然，在另一实施方式中，也可以使遮光结构105为与黑色矩阵104相对应的遮光矩阵，以实现遮光效果。
本实施方式中，所形成的液晶显示器在三维显示模式下，通过在第二基板1012邻近第一基板1011的一侧形成黑色矩阵104，使得可以根据大视角需求来增加黑色矩阵104的宽度以减少双眼信号串扰的现象，而在偏光薄膜103邻近第二基板1012的一侧形成与黑色矩阵104对应的遮光结构105，使得无需增加过宽的黑色矩阵104的宽度而通过遮光结构105的遮光作用即可减少双眼信号串扰的现象，在相同视角要求下，能够相对减小黑色矩阵104中单个黑色带的宽度，从而能提高穿透率和开口率。
此外，一方面，由于偏光薄膜103上形成的对通过偏振光线进行作用的多个区域，这里称为作用区域，也分别对应左图像单元1013和右图像单元1014。另一方面，黑色矩阵104对应左图像单元1013和右图像单元1014之间的区域设置，遮光结构105与黑色矩阵104对应设置。因此，遮光结构105对应偏光薄膜103的作用区域之间设置，在制作偏光薄膜103时以及将遮光结构105设置于偏光薄膜103时，利于遮光结构105在偏光薄膜103的定位和布局，可以采用比较简单和低成本的工艺来获得较高的精度。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
