Description

3D显示装置及其制造方法 技术领域
本发明的实施例涉及一种 3D显示装置及其制造方法。 背景技术
众所周知, 人们平时所见到的 2D显示器无法像真实世界一样提供景深 信息。人们之所以能够辨别景深 (3D效果),关键在于人的两只眼睛具有 60mm 左右的瞳距产生的位置差异。 有 "双眼视差" 的两副图成为一对 "立体图像 对" , 其经过人大脑视觉皮层的融合, 就产生了立体效果。
3D显示模式分为棵眼式 3D显示模式和眼镜式 3D显示模式, 目前, 眼 镜式 3D 显示模式的主流的技术有快门眼镜 ( shutter glass )技术和偏光式 ( pattern retard )技术; 而棵眼式 3D显示模式主要有视差挡板光栅、 柱透镜 光栅等技术, 在棵眼式 3D显示模式中, 视差挡板光栅技术应用最为成熟, 其光栅材料可釆用菲林片式、黑矩阵( BM )式、反射 BM式、可变光栅( Active barrier ) 式等。

为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例的附图,对本发明实施例的技术方案进行清楚、 完整地描述。显然, 所描述的实施例是本发明的一部分实施例, 而不是全部的实施例。 基于所描 述的本发明的实施例, 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
本发明的实施例针对现有技术中的 3D显示器往往只能釆用一种 3D显示 模式的问题,提供一种 3D显示装置及其制造方法, 能够在同一个 3D显示装 置上实现眼镜式 3D显示模式和棵眼式 3D显示模式的兼容切换。
图 2为现有技术中眼镜式 3D显示模式的 3D显示面板的结构示意图,如 图 2所示, 该 3D显示面板由第一偏振片 1、 液晶显示面板 2、 第二偏振片 3、 光栅 4组成。
现有技术中的偏光眼镜式 3D显示模式的原理如图 1所示, 从上到下依 次为: 显示面板显示的画面、 相位差板、 出射画面及观看用的偏光眼镜。 显 示面板上, 一行显示右眼图, 一行显示左眼图,在其前面放置一块相位差板, 一行 λ/2延迟, 一行 0延迟, 一行 λ/2延迟, 一行 0延迟, ..., 一行 λ/2延迟, 一行 0延迟, 如此交替排布, 其中, λ为光波长, 这样可以使 λ/2延迟的像素 出射光的偏光方向旋转 90。, 这样, 戴着左右眼偏振方向正交的偏光眼镜, 就可以右眼只看到右眼像素发出的光, 左眼只看到左眼像素发出的光, 从而 产生立体效果。 此外, 相位差板上的排布还可以是一行 λ/4延迟, 一行 3λ/4 延迟, 一行 λ/4延迟, 一行 3λ/4延迟, ..., 一行 λ/4延迟, 一行 3λ/4延迟。
此相位差板可用液晶显示面板替换, 液晶显示面板可釆用 TN ( Twisted Nematic, 扭曲向列型 )模式或 VA ( Vertical Alignment, 垂直配向 )模式来 实现 0延迟、 λ/2延迟的功能。
而棵眼式 3D显示模式可釆用偏振光栅来实现, 如图 3所示, 现有技术 中棵眼式 3D显示模式的 3D显示面板由第一偏振片 1、 液晶显示面板 2、 第 二偏振片 3、 偏振光栅 5和第三偏振片 6组成。 经过液晶显示面板 2上第二 偏振片 3后的光线, 经过设计好的偏振光栅 5。 所用偏振光栅 5有两个偏振 态区域: 第一区域 7和第二区域 8, 第一区域 7产生 λ/2相位延迟, 经过第 三偏振片 6后, 光线被遮挡; 第二区域 8为 0相位延迟, 经过第三偏振片 6 后,光线仍能射出, 因此通过偏振光栅 5的第三偏振片 6能够实现棵眼式 3D 显示。
为在同一个 3D显示装置上实现眼镜式 3D显示模式和棵眼式 3D显示模 式的兼容切换, 需解决两大主要问题:
一是实现光栅的兼容, 但目前这两种显示模式的光栅条紋的设计和条紋 放置方向均不一样。在偏光眼镜式 3D显示模式中,光栅条紋为横向放置(即 与水平方向平行) , 而在棵眼式 3D显示模式中, 光栅条紋为竖向 (即与水 平方向垂直)或倾斜(即与水平方向成一定角度)放置;
二是第三偏振片 6对偏光眼镜式 3D显示模式的兼容, 第三偏振片 6在 棵眼式 3D显示模式中作为偏光光栅的必用部件,而在眼镜式 3D显示模式中 不仅没有作用, 而且会影响立体显示效果。
本发明的实施例提供了一种 3D显示装置,能够在同一个 3D显示装置上 实现眼镜式 3D显示模式和棵眼式 3D显示模式的兼容切换,如图 4所示,本 实施例包括:
液晶显示面板 2;
分别贴附在液晶显示面板 2两侧的第一偏振片 1、 第二偏振片 3;
位于第二偏振片 3上的光栅功能结构 21 , 光栅功能结构 21的条紋方向 在控制下可与水平方向成预设的不同角度;
位于光栅功能结构 21上的偏振片功能结构 22,偏振片功能结构 22的功 能状态在控制下可在有效和无效之间进行切换, 偏振片功能结构的功能状态 个;偏振片功能结构的功能状态为无效时,入射光均能透过偏振片功能结构。
其中,需要使光栅功能结构 21能够同时适用于眼镜式 3D显示模式和棵 眼式 3D显示模式,光栅功能结构 21的实现例如可以有以下两种可选实施例: 实施例一: 如图 5和图 6所示, 光栅功能结构 21 由位于第二偏振片 3 上的第一光栅单元 9和位于第一光栅单元 9上的第二光栅单元 10组成,其中, 第一光栅单元 9的条紋方向与水平方向平行,第二光栅单元 10的条紋方向与 竖直方向平行, 第一光栅单元 9和第二光栅单元 10均可釆用液晶器件实现。
当需实现偏光眼镜式 3D显示时,控制第一光栅单元 9起作用,为如图 5 所示的横条间隔的图案(pattern ) , 按一行 λ/2延迟, 一行 0延迟, 一行 λ/2 延迟, 一行 0延迟, ..., 一行 λ/2延迟, 一行 0延迟, 如此交替排布; 而控 制第二光栅单元 10均为 0延迟或 1/2 λ延迟, 第二光栅单元 10不起作用。 同时相应驱动液晶显示面板 2的数据内容及格式与偏光眼镜式 3D显示模式 匹配。
而当需实现棵眼式 3D显示时,如图 6所示,控制第一光栅单元 9均为 0 延迟或 1/2 λ延迟, 第一光栅单元 9不起作用; 控制第二光栅单元 10为竖条 间隔的 pattern,按一行 λ/2延迟,一行 0延迟,一行 λ/2延迟,一行 0延迟, ..., 一行 λ/2延迟, 一行 0延迟, 如此交替排布, 充当偏光光栅的核心部件, 同 时相应驱动液晶显示面板 2的数据内容及格式与棵眼式 3D显示模式匹配。
进一步地, 在实现棵眼式 3D显示时, 还可以使第二光栅单元的条紋方 向与竖直方向成一定角度, 这样可以减少摩尔紋。 该角度在 0~90。 之间, 优 选地, 该角度小于 45° , 具体地, 该角度的大小可以根据光栅节距、 显示屏 亚像素节距的大小来设置, 以减小莫尔条紋的宽度, 使得人眼无法分辨出。
实施例二: 光栅功能结构 21釆用一液晶器件实现, 如图 7所示, 该光栅 功能结构 21包括: 相对设置的第一基板 11、 第二基板 13; 位于第一基板 11 和第二基板 13之间的液晶层 12。
第一基板 11上的电极结构如图 8所示, 第一基板 11上设置有与水平方 向平行的多行像素电极, 像素电极的行距为 3-5μπι。 在工艺允许的情况下, 像素电极之间的行距越小越好。 其中奇数行像素电极相互连接并与引线 a连 接,偶数行像素电极相互连接并与引线 b连接; 第二基板 13上的电极结构如 图 9所示,第二基板 13上设置有与竖直方向平行的多行像素电极,像素电极 的行距为 3-5μπι。 在工艺允许的情况下, 像素电极之间的行距越小越好。 其 中奇数行像素电极相互连接并与引线 c连接, 偶数行像素电极相互连接并与 引线 d连接。
为使此液晶器件实现第一光栅单元 9的功能,可将引线0、 d设为与公共 ( common ) 电极相连接, 将引线 a设为与液晶器件的驱动电压 V。p相连接, b设为与 common电极相连接; 或将 b设为与液晶器件的驱动电压 V。p相连 接,、 a设为与 common电极相连接, 从而实现该液晶器件奇偶行间隔具有 0、 1/2 λ相位差的图案延迟, 实现图 5中第一光栅单元 9的功能。
为使此液晶器件实现第二光栅单元 10的功能, 可将引线 、 b设为与公 共( common )电极相连接,将引线 c设为与液晶器件的驱动电压 V。p相连接, d设为与 common电极相连接; 或将 d设为与液晶器件的驱动电压 V。p相连 接,、 c设为与 common电极相连接, 从而实现该液晶器件奇偶行间隔具有 0、 1/2 λ相位差的图案延迟, 实现图 6中第二光栅单元 10的功能。
进一步地,为减小摩尔纹,第二基板 13上的电极结构还可如图 10所示, 第二基板 13上设置有与竖直方向成一定角度的多行像素电极,其中奇数行像 素电极相互连接并与引线 c连接,偶数行像素电极相互连接并与引线 d连接。 与竖直方向所成角度在 0~90° 之间, 优选地, 该角度小于 45° , 具体地, 该角度的大小可以根据光栅节距、 显示屏亚像素节距的大小来设置, 以减小 莫尔条紋的宽度, 使得人眼无法分辨出。
通过上述实施例一和实施例二可以使得光栅功能结构 21 能够同时适用 于眼镜式 3D显示模式和棵眼式 3D显示模式。
下面需要解决偏振片功能结构 22对眼镜式 3D显示模式和棵眼式 3D显 示模式的兼容。
实施例三:
如图 lla~c所示, 偏振片功能结构 22釆用液晶器件实现, 包括: 相对设置的第三基板 14、 第四基板 16;
位于第三基板 14和第四基板 16之间、 由向列相液晶和二色性染料 17 组成的液晶分子 15;
其中, 液晶分子 15的初始取向为与第三基板 14平行, 在对偏振片功能 结构 22施加电场后, 液晶分子 15的取向与第三基板 14垂直。
在液晶材料中加入二色性染料, 此二色性染料具有如下特征: 其对入射 光束两个正交的线偏振光分量, 仅选择吸收其中一个而让第二个通过。
液晶盒中液晶分子 15的初始取向为上下平行或反平行取向(即与第三基 板 14平行), 其与经过此液晶盒的入射偏振光偏振方向平行或垂直, 若偏振 的入射光与液晶分子 15指向矢平行,则该区域的光线被吸收,该区域充当光 栅的挡光条, 如图 11 ( a )所示; 若偏振的入射光与液晶分子 15指向矢垂直, 则该区域的光线能顺利通过, 此区域充当光栅开口, 如图 11 ( b )所示; 因 此, 通过掺杂二色性染料的液晶器件, 可充当偏振片的功能, 实现棵眼式 3D 显示。
另外, 当 3D显示装置切换到偏光眼镜式 3D显示模式时,需取消偏振片 功能结构 22的偏振片功能,保证左右眼看到不同偏振态的图像。 此时, 只需 对该液晶器件施加电场,使液晶分子 15沿电场方向取向,如图 11 ( c )所示, 此时,入射光的偏振方向均与液晶分子 15指向矢垂直,光线均能通过。因此, 对偏光眼镜式 3D显示模式的实现没有产生负面影响。
通过上述实施例三可以使得偏振片功能结构 22 能够同时适用于眼镜式 3D显示模式和棵眼式 3D显示模式。
本发明的实施例的 3D显示装置, 可实现眼镜式 3D显示模式和棵眼式
3D显示模式的兼容切换,其中,光栅功能结构的条紋方向在控制下与水平方 向成不同角度, 偏振片功能结构的功能状态在控制下在有效和无效之间进行 切换。 通过控制光栅功能结构的条紋方向和偏振片功能结构的功能状态, 可 以使得 3D显示装置在眼镜式 3D显示模式和棵眼式 3D显示模式之间进行切 换。
进一步地, 本发明实施例的 3D显示装置还能实现 2D显示和 3D显示之 间的切换,只需要控制光栅功能结构 21的第一光栅单元 9、第二光栅单元 10 和偏振片功能结构 22同时不起作用, 即可实现 2D显示。
本发明实施例还提供一种与上述 3D显示装置相应的 3D显示装置的制造 方法, 包括:
形成液晶显示面板;
在液晶显示面板两侧分别形成第一、 第二偏振片;
在第二偏振片上形成光栅功能结构, 光栅功能结构的条紋方向可在控制 下可与水平方向成预设的不同角度;
在光栅功能结构上形成偏振片功能结构, 偏振片功能结构的功能状态在 控制下可在有效和无效之间进行切换,偏振片功能结构的功能状态为有效时, 功能结构的功能状态为无效时, 入射光均能透过偏振片功能结构。

上述装置中所有实现手段和应用场景均适用于该方法的实施例中, 也能 达到相同的技术功能状态, 在此不再赘述。
在本发明的各方法实施例中, 所述各步骤的序号并不能用于限定各步骤 的先后顺序,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下, 对各步骤的先后变化也在本发明的保护范围之内。
以上所述仅是本发明的示范性实施方式, 而非用于限制本发明的保护范 围, 本发明的保护范围由所附的权利要求确定。
