Description

菲涅尔液晶透镜面板、其制备方法及3D显示器 技术领域
本发明涉及液晶显示技术领域，尤其涉及一种用于裸眼立体显示的菲涅尔液晶透镜面板、其制备方法及包括这种菲涅尔液晶透镜面板的3D显示器。
背景技术
人类的视觉是立体的，即每只眼睛所看见的世界的图像稍有不同。大脑融合这两幅图像(称之为立体配对)，以给出景深的感觉。3D立体显示的原理是：向每只眼睛重放与观看现实世界的景象所看到的独立图像(通常是平面的)，大脑对两幅独立图像再次融合该立体配对，以给出图像中的景深感觉，即立体效果。在实现立体显示的技术中，裸眼立体显示由于无需观看者使用眼镜的优点使得它在立体显示领域中而得到广泛应用。
目前，实现裸眼立体显示技术的主要方式是通过在显示面板前设置光栅，在水平方向上将显示面板的像素单元分割为奇数列像素和偶数列像素，从而为观看者的左右眼分别提供两幅不同的图像，利用观看者左眼图像和右眼图像的视差效应形成景深，进而产生立体显示效果。现有的光栅包括黑白视差障碍光栅和柱状物理透镜等。然而，由于普通光栅的光距不可调节，只能限制观众在某个特定的观看距离范围内观看，灵活性和观看距离有限，这限制了光栅式立体显示技术在生活中的应用。为此，业界开发了可以通过电压调节光栅栅距的液晶障碍光栅和液晶透镜。
图1为现有技术采用液晶透镜的裸眼立体显示液晶面板的水平剖面示意图。请参照图1，在观看者的方向上，该裸眼立体显示液晶面板自下至上包括：2D显示面板100和设置在2D显示面板100上部的3D透镜面板。
该2D显示面板100包括：第三玻璃基板110、第四玻璃基板120以及填充于两者之间的液晶层130。在第三玻璃基板110的上部设置有上偏光片111。
该3D透镜面板包括：上透明基板200、下透明基板300以及填充于两者之间的液晶材料400。下透明基板300通过粘结层112固定于设置在 2D显示面板100上部的上偏光片111上，在上透明基板200的内侧面设置面状的第一电极210，在下透明基板300的内侧面设置长条状的第二电极310。其中，在第一电极210和第二电极310之间施加驱动电压的情况下，液晶分子进行偏转。通过在预设区域内的不同位置施加不同的驱动电压，使得液晶分子的偏转方向不同，从而形成梯度折射率分布式液晶透镜，即格林液晶透镜(GRIN Elens)。在该GRIN Elens的作用下，2D显示面板的部分画面投射至左眼，另一部分画面投射至右眼，通过将左眼和右眼的可视画面分开，使观众看到3D影像。
然而，对于图1所示的裸眼立体显示液晶面板而言，由于液晶材料的折射率仅为0.1左右，导致液晶盒的厚度太大。而大盒厚液晶面板不仅增加了制作工艺的难度和成本，并且不利于市场的推广。
已研发了采用菲涅尔透镜代替GRIN Elens以减小裸眼3D显示液晶面板厚度的技术。图2A为菲涅尔透镜和传统透镜结构关系的示意图。请参照图2A，在菲涅尔透镜中，梯度折射率变化透镜切割成具有多个同心圆布置的环形透镜，并将基准面下移至同一水平位置，而表面的弯曲度与梯度折射率变化相对应，如此一来，透镜的厚度可以大大降低。
图2B为采用菲涅尔透镜原理的液晶面板的剖面示意图。请参照图2B，两基板之间的填充液晶材料，该液晶材料被分为若干个透镜区域。对于一透镜区域而言，在该透镜区域内不同的第二电极施加不同的驱动电压，从而使该透镜区域的液晶分子偏转不同的角度，从而形成菲涅尔液晶透镜。该菲涅尔液晶透镜中的每一个折射率连续的部分称为一旁瓣431、432。
然而，在现有技术中，菲涅尔液晶透镜相邻旁瓣之间经常有重叠或者交叉的区域存在，两者之间的界限不是特别明晰，导致透镜区域内部产生光串扰，应折射到左眼的光线折射到右眼，反之亦然，影响了3D显示效果。
此外，现有技术的菲涅尔液晶透镜面板中，上、下透明基板之间采用球形光隔离件或间隙子(Photo Spacer，简称PS)来支撑，由于球形光隔离件位置不固定，经常会移动到液晶透镜的中间区域，进一步增大了立体显示的串扰。

另外，在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下，公知的结构和装置以图示的方式体现以简化附图。
根据本发明总体上的发明构思，提供一种菲涅尔液晶透镜面板，包括：第一基板，包括第一透明基板及形成于第一透明基板内侧面的第一电极；第二基板，包括相对于所述第一透明基板设置的第二透明基板及形成于第二透明基板内侧面的间隔布置的带状的多个第二电极；液晶层，填充于所述第一基板和第二基板之间的空间，并被分为多个透镜区域，对于任一透镜区域而言，在该透镜区域内的第二电极施加不同的驱动电压的情况下，该透镜区域内的液晶分子偏转不同的角度以形成菲涅尔液晶透镜；以及多 个绝缘阻隔块，每个绝缘阻隔块位于所述第二基板内侧且设置在所述菲涅尔液晶透镜的两个相邻旁瓣之间。
图3为根据本发明实施例的用于裸眼立体显示的菲涅尔液晶透镜面板的水平剖面示意图，图中示出了一个透镜区域。
请参照图3，本实施例用于裸眼立体显示的菲涅尔液晶透镜上前至下包括：第一基板，包括上透明基板200及形成于该上透明基板200内侧面的第一电极210；第二基板，包括相对于上透明基板200设置的下透明基板300及形成于下透明基板300内侧面的间隔布置的带状的第二电极310；液晶层400，填充于第一基板和第二基板之间的空间，其被分为多个透镜区域，对于任一透镜区域而言，在该透镜区域内的第二电极310施加不同的驱动电压的情况下，该透镜区域内的液晶分子偏转不同的角度以形成菲涅尔液晶透镜；以及多个绝缘阻隔块(421～424)，每个绝缘阻隔块位于所述第二基板内侧且设置在所述菲涅尔液晶透镜的两个相邻旁瓣之间。
在本发明实施例的菲涅尔液晶透镜面板中，在相邻透镜区域的边界处设有光隔离件或间隙子(Photo Spacer，简称PS)410，以阻挡一个透镜区域中的光进入相邻的另一透镜区域。
本实施例的菲涅尔液晶透镜中，对于一透镜区域而言，在该透镜区域内不同的第二电极施加不同的驱动电压，从而使该透镜区域的液晶分子形成菲涅尔液晶透镜。在该菲涅尔液晶透镜的两旁瓣之间，设置有固定于第二基板内侧的绝缘阻隔块(421～424)以减弱电场对位于菲涅尔液晶透镜左右两侧液晶分子的影响。在一种示例性实施例中，该光隔离件410和绝缘阻隔块(421～424)均由树脂材料制备。
本实施例中，上透明基板和下透明基板均采用玻璃材料制成，本领域技术人员也可以根据需要选择其他材料的透明基板，例如透明树脂基板，本发明并不对此进行限制。
在上透明基板200的内侧面的第一电极210呈面状分布。在透明基板300的内侧面具有若干个平行条带状分布的第二电极310。第二电极在下透明基板上可以沿列的方向设置，也可以倾斜设置。例如，第二电极的延伸方向与配合使用的2D显示面板的一个侧边的延伸方向成70～90度的夹角。一般情况下，第一电极和第二电极均为掺锡氧化铟ITO形成。
为了提升立体显示的效果，本领域的技术人员可以理解，在第一电极210的内侧设置上配向层，在第二电极310的内侧设置下配向层。
液晶层400填充于第一基板和第二基板之间的空间。被分为若干个透镜区域。每一透镜区域可以包含2～9个子像素。每个透镜区域至少跨越三条第二电极，在不同的第二电极施加不同的驱动电压的情况下，该透镜区域的液晶分子偏转的角度不同，从而形成菲涅尔液晶透镜。
本实施例中，以透镜区域沿倾斜方向设置为例进行说明，如图4所示。需要说明的是，透镜区域还可以沿行或列的方向，其设置方式与本实施例类似，此处不再详细说明。
光隔离件410设置于第一基板和第二基板之间，相邻透镜区域的边界处，以隔开第一基板和第二基板，其至少固定于第二基板的内侧，例如固定于第二透明基板300上；固定于第二电极310上；或者同时固定于所述第二透明基板(300)和第二电极(210)上。
如图3所示，每个光隔离件410呈圆台状，其高度方向上的剖面形状为等腰梯形。如图5所示，该等腰梯形的高度H1、底边长度L11和顶边长度L12均与菲涅尔液晶透镜面板的盒厚H有关，例如，满足：
H≤H1≤1.1H，L11≤5H，L12≤3H，L12≤L11  (1)
需要说明的是，除了圆台状之外，该光隔离件还可以是圆柱状、棱柱状、棱台状等多种形状。此外，该光隔离件设置的位置及密度同现有技术中相同，此处不再进行详细描述。
本实施例中，光隔离件410固定在第二基板上。由于光隔离件位置固定，不会移动到液晶子像素的位置，避免了串扰情况的发生。
在透镜区域内的液晶形成菲涅尔液晶透镜。该菲涅尔液晶透镜的各旁瓣之间的第二电极上设置条带状的绝缘阻隔块，以减弱形成于透镜区域中的电场对左右两侧液晶分子的影响。
本实施例中，绝缘阻隔块固定于第二基板，呈圆台状，其固定方向上的剖面形状为等腰梯形。该梯形的高度H2小于菲涅尔液晶透镜面板的盒厚H，即H2＜H，其底边长度L21和顶边长度L22均小于条带状第二电极的宽度L，且L22≤L21。在一种示例性实施例中，3μm≤H2≤5μm，2μm≤L21≤5μm，0μm≤L22≤4μm。
请参照图3，在菲涅尔液晶透镜中，位于中心线两侧的绝缘阻隔块相互对称。本实施例中，绝缘阻隔块421和424对称，422和423对称，对应的两绝缘阻隔块的尺寸和形状大致相同，以对电场产生基本上相同的作用。
需要说明的是，除了圆台状之外，该绝缘阻隔块还可以为圆柱状、圆锥状、棱柱状、棱台状或棱锥状等多种形状，本发明不对其进行限制。
本发明中，光隔离件和绝缘阻隔块均采用树脂材料制备。其中，制备光隔离件的树脂材料的透过率大于90％，粘度大于10mpa.s。制备绝缘阻隔块的树脂材料的透过率大于90％，粘度大于3mpa.s。
本实施例中，为了简化制备工艺，光隔离件和绝缘阻隔块的树脂材料相同。该树脂材料采用溶质材料和溶剂材料配比而成，通过控制溶剂含量来控制树脂材料的粘度。
本实施例中，溶质材料选自以下材料其中之一：JSR公司的NN856、大阪有机化工的KMH-T546、JSR公司的JSM-548-SS1。溶剂材料选自于：EDM(乙二醇二甲醚)和PGMEA(丙二醇甲醚醋酸酯)。为了满足树脂材料粘度的要求，制备光隔离件和绝缘阻隔块的树脂材料中，溶剂含量均小于等于70％。
以下介绍本实施例菲涅尔液晶透镜面板的制备过程。在该制备过程中，所采用的掩模板包括具有与绝缘阻隔块和光隔离件的形状相对应的通孔的第一掩模板、及具有与光隔离件的形状相对应的通孔的第二掩模板。
图6为制备图3所示菲涅尔液晶透镜面板过程中执行各步骤后的器件的局部剖面示意图。在图6及后续的图8中，为了简单起见，实际上在高度方向上具有梯形剖面的圆台状光隔离件和绝缘阻隔块均表示为矩形剖面的圆柱状。请参照图6，图3所述菲涅尔液晶透镜面板的制备过程包括如下步骤：
步骤A：在下透明基板300上制作条带状的第二电极310，并形成第二基板，如图6中A所示。
步骤B：在第二基板上涂布树脂材料，如图6中B所示。该树脂材料的构成以及配置过程已在前说明，此处不再重述。树脂材料的涂布厚度大于等于光隔离件的高度。
步骤C：对树脂材料进行刻蚀，在将要形成光隔离件和绝缘阻隔块的位置形成高度为H1的第一凸起，其中，H1为光隔离件的预设高度。
该步骤C具体包括如下步骤：
子步骤C1：在树脂材料上涂布光刻胶材料，如图6中C1所示；
在一种示例性实施例中，光刻胶材料选用负性光刻胶材料，例如，可以选用目前液晶显示器(LCD)行业通用的材料即可；
子步骤C2：采用第一掩模板在光刻胶材料上进行曝光，如图6中C2所示；在掩模板上设有与光隔离件和绝缘阻隔块的形状相对应的通孔。
子步骤C3：去除曝光后的光刻胶，形成掩模图形，如图6中C3所示；
子步骤C4：利用掩模图形对树脂材料进行刻蚀，如图6中C4所示；
子步骤C5：去除残余光刻胶，得到同等高度的间隔布置的多个第一凸起，如图6中C5所示；
需要说明的是，在对树脂材料进行刻蚀的过程中，通过对工艺条件的控制，可以形成与将要形成的圆台状的光隔离件和绝缘阻隔块形状一致的第一凸起，其操作工艺在本领域内已公知，此处不再详细说明。
执行本步骤C5后，多个第一凸起的高度均等于将要形成的光隔离件的预设高度H1，在后续步骤中，还需要对部分第一凸起的高度进行再次降低。
步骤D：对树脂材料进行再次刻蚀，并保持位于外侧的、将要形成光隔离件的第一凸起的高度不变，降低将要形成绝缘阻隔块的其余第一突起的高度，直至到达绝缘阻隔块的预设的高度H2，形成第二凸起；
该步骤D具体包括如下步骤：
子步骤D1：再次在第二基板上涂布光刻胶，如图6中D1所示；
子步骤D2：利用具有与光隔离件的形状相对应的通孔的第二掩模板对光刻胶进行曝光，如图6中D2所示；

子步骤D5：去除残余的光刻胶，在第二基板上得到成型的用做光隔 离件的第一凸起和用做绝缘阻隔块的第二凸起，如图6中D5所示；
步骤E：将第一基板对盒于具有光隔离件和绝缘阻隔块的第二基板，其中，该第一基板包括上透明基板200及形成于其内侧面的第一电极210；
步骤F：在第一基板和第二基板之间填充液晶材料，至此，本发明第一实施例的用于裸眼立体显示的菲涅尔液晶透镜面板制备完毕。

图7为根据本发明第二实施例用于裸眼立体显示的菲涅尔液晶透镜的水平剖面示意图。如图7所示，光隔离件包括在高度方向上相互对准的第一部分和第二部分，其中：第一部分为圆台状，固定于第二基板的内侧，其高度与所述绝缘阻隔块的高度相同；第二部分为倒圆台状，固定于第二基板内侧，并与第一部分的在高度方向上相互对准。由于光隔离件位置固定，不会移动到液晶子像素的位置，避免了光串扰情况的发生。
每个光隔离件的第一部分的高度为H11，为了减弱第一部分和第二部分在叠置时发生的轻微形变，第二部分的高度H12略高于液晶透镜盒厚H减掉第一部分的高度为H11，形变量的大小与选用材料有关，例如一般＜10％，即满足：
H≤H11+H12≤1.1H  (2)
