以下，根据附图对本公开的实施例提出的滤色器基板、其制造方法及 3D 显示装置进行详细说明。
实施例一
如图 1所示， 依照本公开的实施例一的滤色器基板包括： 玻璃基板 4、 彩色滤光单元 1、 以及玻璃基板 4与彩色滤光单元 1之间的柱状透镜结构。 其中， 本实施例的滤色器基板中， 彩色滤光单元 1为彩色滤光树脂层， 优选 为三基色彩色滤光树脂层， 该三基色可以是红绿蓝三种颜色， 也可以是其它 任意满足三基色条件的三种颜色。 彩色滤光树脂层还可为四基色或其它任一 种滤光树脂层， 在此不作为对本公开的实施例技术方案的限制。
示例性地， 在本实施例中， 该柱状透镜结构为多个柱状透镜周期性排列
(如图 1中所示， 以三基色彩色滤光树脂为例， 每个透镜的一半对应一组红 绿蓝彩色滤光树脂中的一种颜色的滤光树脂， 但不限于此）构成的柱状透镜 阵列， 每个柱状透镜由具有不同折射率的两种透镜组成。
示例性地， 不同折射率的两种透镜自玻璃基板 4至彩色滤光树脂层分别 为平 IHJ透镜 3以及平凸透镜 2,平凸透镜 2对应嵌合于平 IHJ透镜 3。平凸透镜 2的折射率 ηι大于平凹透镜 3的折射率 n2 ,并且平凹透镜 3的折射率《2等于 玻璃的折射率《3。 备选地， 为了不影响成像（即光线的路径） ， 平凸透镜 2 与平凹透镜 3的弧面曲率相同，平凸透镜 2的厚度 //等于平凸透镜 2的物方 焦距 /。
备选地， 本公开的实施例还提供一种滤色器基板， 与上述滤色器基板的 不同之处在于， 所述柱状透镜由一层凹透镜组成或者由一层凸透镜组成。 该 结构更利于减少工艺流程、 降低成本。
备选地，形成在基板与彩色滤光单元之间的柱状透镜可以釆用其他结构， 例如四分之一圓透镜， 只要能将显示器的各个像素出射的光分别入射到观察 者的左眼和右眼即可。
实施例二
本公开的实施例还提供了一种包括上述滤色器基板的 3D显示装置， 例 如液晶显示装置、 OLED显示装置等显示装置。 除上述滤色器基板外， 3D显 示装置的其它构件为根据现有技术制造的构件， 例如， 阵列基板等， 在此不 这些构件的制造工艺例如阵列基板与该滤色器基板之间填充液晶以及对盒工 艺等。
本公开的实施例的 3D显示装置的显示原理如下：
如图 2所示， 考查平凸透镜 2上的一个点光源 5 , 假设平凸透镜 2的厚 度/ 等于物方焦距 /, 从点光源 5发出的光线经过透镜后以平行光出射， 所 以只考察其中一条光线。在平凸透镜 2中，从点光源 5发出的光到达点 6后， 凸面的界面两侧折射率不同。 由于平凸透镜 2的折射率 大于平凹透镜 3的 折射率 n2, 因此， 根据 Snell定律： sin α = η2 ύη β , 入射角《 (入射光线 10 与法线 8的夹角）小于折射角 （折射光线 1 1与法线 9的夹角）。 同理， 光 线从透镜 3出射到空气（折射率等于 1 )时， 入射角 β (入射光线 1 1与法线 9的夹角） 小于折射角 7 (折射光线 12与法线 9的夹角） 。 因此， 从点光源 5发出的光线经过透镜后， 总体上是向右传播的。
综上所述，如图 2和图 3所示， 由左侧的彩色滤光树脂 13出射的光线经 过平凸透镜 2和平凹透镜 3后， 光线出射的方向向右， 到达左眼 16; 同理， 由右侧的彩色滤光树脂 14出射的光线经过平凸透镜 2和平凹透镜 3后，光线 出射的方向向左， 到达右眼 15。 即， 左侧的彩色滤光树脂成像到达左眼， 右 侧的彩色滤光树脂成像到达右眼。 因此， 左右眼分别只看到左眼图像和右眼 图像， 经过大脑合成进而形成了 3D图像。

以上步骤也可釆用本领域所熟知的其它具体工艺， 在此不作赘述。 在完 成上述步骤之后， 按照本领域所熟知的工艺制备阵列基板， 并将阵列基板和 上述滤色器基板对盒即可形成本公开的实施例的 3D显示装置。
以下将给出具体示例来详细描述本实施例中平凹透镜和平凸透镜的制造 尺寸。
示例性地， 如图 4所示， 在本实施例的 3D显示装置的滤色器基板中， 平凹透镜 3与平凸透镜 2的弧面均为半圓， 且曲面的曲率半径 等于彩色滤 光树脂尺寸；？。 其中， 为人眼的瞳距， D为观看者的眼睛与显示装置之间 的距离， h为平凸透镜 3的顶点 6到玻璃基板表面的垂直距离。
根据透镜的成像原理得到平凸透镜 2的高度， 即顶点 6到彩色滤光单元 的垂直距离 H。
由平凸透镜的成像原理可以得到焦距与曲率半径的关系：
"1 _ "2 ( 1 )
又因为 ?=/?， 所以
f = H = 2n1 -Ii p
"「"2 ( 2 ) 得到平凸透镜厚度/ /之后， 通过 Snell定律计算平凹透镜 2的尺寸， 即 顶点 6到玻璃表面的距离 h。
光线通过平凸透镜 2与平 IHJ透镜 3界面时的折射关系是：
nx sin a = n2 sin β ( 3 )
其中 = arctanO/ ) , 那么 β = arcsin [― sin(arctan―)]
n2 H (4)
光线从玻璃基板的界面到空气中时：
Figure imgf000007_0001
所以 r^arcsinf^ sin(arctan— )1
H (6) 最后通过人眼瞳距与观察距离的几何关系可以得到：
htm β + Dtmy = Wp (7)
将式（ 4 ) 、 (6)代入式（ 7 )可以求得平凹透镜厚度 h。
Wv -Dtanr
h =」 - tan^ (8) 综上， 获得了平凹透镜和平凸透镜的计算公式， 在实际制造工艺中， 首 先利用上述公式得到待制造的平凸透镜和平 IHJ透镜的具体尺寸， 从而制造出 具有该尺寸的平凸透镜和平 IHJ透镜。
以下给出具体的数值示例来计算平凸透镜和平凹透镜的尺寸， 例如： 彩 色滤光树脂尺寸 p为 0.05mm; 平凸透镜的折射率 等于 1.56, 平凹透镜 3 的折射率《2与玻璃基板的折射率相同， 等于 1.5; 在液晶盒和观察者之间的 距离 D为 280mm; 人眼的瞳距 为 65mm; 由以上公式可以计算得到： 平 凸透镜 2与平凹透镜 3的弧面的曲率半径是 0.05mm, 平凸透镜的顶点 6与 彩色滤光树脂之间的距离 //为 1.35mm, 平 IHJ透镜的顶 6与玻璃基板表面的 距离 2为 1.267mm。 这样， 在制造滤色器基板的工艺中， 利用上述具体数值 来制造具有上述尺寸的平凸透镜和平凹透镜。
以上实施方式仅用于说明本公开的实施例， 而并非对本公开的实施例的 限制， 有关技术领域的普通技术人员， 在不脱离本公开的实施例的精神和范 围的情况下， 还可以做出各种变化和变型， 因此所有等同的技术方案也属于 本公开的实施例的范畴，本公开的实施例的专利保护范围应由权利要求限定。
