Description

图案化相位延迟膜及显示装置 技术领域
本发明涉及显示技术领域，特别涉及一种图案化相位延迟膜及显示装置。
 背景技术
传统的利用图案化相位延迟膜（FPR，Film-type Patterned Retarder）进行三维图像显示的技术方案为：
将传统的图案化相位延迟膜20贴附于显示面板10的出光侧。
显示面板10所发出的图像光线在经过彩色滤光片（CF，Color Filter）基板侧的偏光片（PF，Polarized Film）后变成线偏振光。所述线偏振光经过图案化相位延迟膜20后会形成右旋圆偏振光和左旋圆偏振光。
所述右旋圆偏振光和所述左旋圆偏振光在经过观看者的眼镜镜片后分别透过左眼镜片和右眼镜片，从而使得观看者能够观看到左右眼图像。
其中，如图1所示，传统的图案化相位延迟膜20包括至少两相位延迟部（201、202），所述相位延迟部为矩形长条状，至少两所述相位延迟部平行排列在一起，相邻两所述相位延迟部之间的分界线203位于所述显示面板10的两子像素之间的间隙处，例如，所述显示面板10的蓝色子像素位于红色子像素上方，所述分界线203位于蓝色子像素和红色子像素之间的间隙处。
在实践中，发明人发现现有技术至少存在以下问题：
如图2所示，在上述三维图像显示的技术方案中，由于在所述分界线203的上方为蓝色的子像素，在所述分界线203的下方为红色的子像素，因此上视角看到的画面会偏红，下视角看到的画面会偏蓝，即，会出现色偏（Color Shift）问题。

 本发明的最佳实施方式
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。
本说明书所使用的词语“实施例”意指用作实例、示例或例证。词语“实施例”的使用旨在以具体方式提出概念。本说明书和所附权利要求中所使用的冠词“一”一般地可以被解释为意指“一个或多个”，除非另外指定或从上下文清楚导向单数形式。
参考图3，图3为本发明显示装置的第一实施例的示意图。
本实施例的显示装置包括：显示面板10和图案化相位延迟膜20，所述图案化相位延迟膜20贴附于所述显示面板10上。所述显示面板10包括至少两个第一子像素101、至少两个第二子像素102和至少两个第三子像素103。所述显示面板10可以是LCD（Liquid Crystal Display，液晶显示）面板，也可以是OLED（Organic Light Emitting Diode，有机发光二极管）面板。本发明的显示装置可以用于显示二维图像，也可以用于显示三维图像，还可以用于从二维图像显示的模式切换到三维图像显示的模式。
在本实施例中，所述显示面板10中的像素设置为三栅极（Tri-gate）结构，即，所述显示面板10中所述第一子像素101、所述第二子像素102和所述第三子像素103沿第一方向301排列。这样有利于减少所述显示面板10中的数据线（Data Line）的数量，从而减少数据信号处理芯片（Source IC）的数量；虽然由此会导致栅极线（Gate Line）/扫描线（Scan Line）的数量增多，以及导致扫描信号处理芯片（Gate IC）数目增加，但是数据信号处理芯片成本较高，因此，采用三栅极像素结构，可以减少数据信号处理芯片数量，降低成本。其中，所述第一方向301平行于所述数据线所对应的直线。
在本实施例中，所述第一子像素101、所述第二子像素102和所述第三子像素103分别为红色（R，Red）子像素、绿色（G，Green）子像素和蓝色（B，Blue）子像素。
在本实施例中，所述图案化相位延迟膜20包括：图案化相位延迟膜主体。其中，所述图案化相位延迟膜主体包括：至少两相位延迟部（第一相位延迟部201、第二相位延迟部202）。至少两所述相位延迟部沿所述第一方向301并列排列在一起，即，所述图案化相位延迟膜主体包括相位延迟部阵列（至少包括第一相位延迟部201、第二相位延迟部202），所述相位延迟部阵列的阵列方向为第一方向301。
所述相位延迟部具有第一锯齿部和第二锯齿部，所述第一锯齿部和所述第二锯齿部分别设置于所述相位延迟部的相对的两侧，所述第一锯齿部的形状与所述第二锯齿部的形状对应；所述第一锯齿部和所述第二锯齿部均与至少一个所述第一子像素101、至少一个所述第二子像素102和至少一个所述第三子像素103相邻。相邻两所述相位延迟部拼接（耦合）在一起。
相邻两所述相位延迟部分别为正四分之一相位延迟部（1/4λ）和负四分之一相位延迟部（-1/4λ）。
所述第一锯齿部的第一边缘和所述第二锯齿部的第二边缘均设置为阶梯状。
所述第一边缘和所述第二边缘均设有至少两个梯级，所述梯级与所述第一子像素101、所述第二子像素102和所述第三子像素103中的一者对应，即，一个所述梯级覆盖且仅覆盖所述第一子像素101、所述第二子像素102和所述第三子像素103中的一者。这样有利于使得所述第一边缘和所述第二边缘周期性地与所述第一子像素101、所述第二子像素102和所述第三子像素103对应，而不会与至少两个相邻的相同的子像素（所述第一子像素101、所述第二子像素102、所述第三子像素103）对应，即，所述第一边缘和所述第二边缘周期性地排布有：一个且一个所述第一子像素101（R子像素）、一个且一个所述第三子像素103（B子像素）、一个且一个所述第二子像素102（G子像素），或者，所述第一边缘和所述第二边缘周期性地排布有：一个且一个所述第二子像素102（G子像素）、一个且一个所述第三子像素103（B子像素）、一个且一个所述第一子像素101（R子像素）。这样可以防止显示装置出现色偏问题，提高三维图像的显示质量。
在本实施例中，所述第一锯齿部和所述第二锯齿部所对应的梯级是连续的，即，所述梯级所对应的高度是沿第二方向302连续递增或连续递减的，并且，所述梯级高度的递增或递减是周期性变化的，其中，所述第二方向302与所述第一方向301垂直。相邻两梯级之间没有大于一个子像素（所述第一子像素101、所述第二子像素102、所述第三子像素103）高度的落差（高度差），即，相邻两梯级之间的均具有且仅有一个子像素（所述第一子像素101、所述第二子像素102、所述第三子像素103）的高度差。
所述显示面板10中的所述第一子像素101、所述第二子像素102和所述第三子像素103中的任意两者之间设置有间隙，所述第一边缘和所述第二边缘均位于所述间隙所对应的范围内。
所述间隙与所述显示面板10中的黑色矩阵（BM，Black Matrix）中的间隔条对应，即，所述第一边缘和所述第二边缘与所述黑色矩阵中的部分所述间隔条重叠（重合），这样，有利于使得所述相位延迟部完整地覆盖所述第一子像素101、所述第二子像素102、所述第三子像素103中的至少一者，而不是仅覆盖所述第一子像素101、所述第二子像素102、所述第三子像素103中的至少一者中的一部分，从而有利于防止影像串扰（Crosstalk）现象的发生。
参考图4，图4为本发明显示装置的第二实施例的示意图。本实施例与上述第一实施例相似，不同之处在于：
在本实施例中，所述第一锯齿部和所述第二锯齿部所对应的梯级是不连续的，即，所述梯级所对应的高度是沿第二方向302跳跃式（跨越式）递增或跳跃式（跨越式）递减的，并且，所述梯级高度的递增或递减是周期性变化的，其中，所述第二方向302与所述第一方向301垂直。相邻两梯级之间的落差（高度差）大于或等于一个子像素（所述第一子像素101、所述第二子像素102、所述第三子像素103）的高度，即，相邻两梯级之间的均至少具有一个子像素（所述第一子像素101、所述第二子像素102、所述第三子像素103）的高度差。
所述第一边缘和所述第二边缘均设有至少两个梯级，所述梯级与所述第一子像素101、所述第二子像素102和所述第三子像素103中的至少一者对应，即，一个所述梯级覆盖至少一个子像素（所述第一子像素101、所述第二子像素102、所述第三子像素103）。
这样有利于使得所述第一边缘和所述第二边缘周期性地与所述第一子像素101、所述第二子像素102和所述第三子像素103对应，而不会与至少两个相邻的相同的子像素（所述第一子像素101、所述第二子像素102、所述第三子像素103）对应，即，所述第一边缘和所述第二边缘所对应的任意三个连续的子像素（所述第一子像素101、所述第二子像素102和所述第三子像素103）均不相同。这样有利于防止显示装置出现色偏问题，提高三维图像的显示质量。
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。
