本发明涉及显示技术领域，具体是涉及一种立体显示装置及其制造方法。
随着技术的发展， 立体显示技术已发展出多种显示模式来使观察者产生 立体视觉。 立体视觉的产生是由于人的左右眼接收到了不同角度的图像， 经 大脑合成后， 感知到物体的层次感及深度感。
如图 1所示， 为现有一种立体显示装置的结构示意图， 该立体显示装置 包括偏光控制单元 100和液晶显示单元 200， 偏光控制单元 100包括第≡基 板 101和第四基板 110, 第四基板 110通过粘合胶 300与液晶显示单元 200 的第一偏光片 201贴合在一起， 在第四基板 110上还设有黑矩阵 109以及在 黑矩阵上设有平坦层 106。 现有立体显示装置由 PCP ( Polarization control panel)盒与 LCD (Liquid Crystal Display)盒贴合构成， 厚度较厚， 接近普通 LCD 面板的两倍。 现有的立体显示装置通过 PCP盒与 LCD盒贴合而成， 制 作工艺较为复杂， 需要在制作完成的 TFT基板迸行曝光、 显影、 刻蚀、 剥离 等步骤， 成本比较高。 而且， 在进行 PCP盒与 LCD盒贴合的过程中会存在 偏差， 从而影响到显示效果。 并且由于 PCP盒与 LCD盒是遥过贴合胶进行 贴合固定， 一旦其中一个产生质量问题， 会导致立体显示装置整体质量问题， 从而增加了报废成本。
为了解决现有的立体显示装置的厚度较厚、 贴合中存在偏差这一技术问 题， 本发明提供了一种立体显示装置及其制造方法。
本发明采用的技术方案是： 一种立体显示装置， 包括：
液晶显示单元， 包括第一偏光片、 第一基板、 第二基板和设置在两个基 板之间的液晶层， 所述第一基板在远离液晶层的面上设有第一偏光片；

优选地， 所述第一偏光片和第二电极之间还设有平坦层。
优选地， 所述第一基板为彩膜基板。
优选地， 所述第一基板和 /或者第二基板包括玻璃基板、 石英基板或者有 机基板中的一种。
本发明还提供了一种立体显示装置的制造方法， 包括：

在第三基板的另一面上设置四分之一波片。
本发明的立体显示装置将液晶显示单元的基板作为偏光控制单元的其中 一个基板， 省掉了偏光控制单元中周边黑矩阵的刻蚀， 节省了原料， 降低了 成本； 遥过直接在液晶显示单元的基板外侧设置电极等部件， 可节省一张基 板， 避免了贴盒胶的使用， 使得立体显示成本大大降低。 另外， 由于本发明 的立体显示装置不存在对盒贴合的过程， 降低了调试时间， 同^使得贴 ^公 差 ¾1小。

为使本发明要解决的技术问题、 技术方案和优点更加清楚， 下面将结合 附图及具体实施方式进行详细描述。
如图 2所示， 为本发明一实施方式的立体显示装置的结构示意图， 包括 偏光控制单元 100和液晶显示单元 200， 其中， 液晶显示单元 200包括第一 基板 202、第二基板 204和设置在两个基板之间的液晶层 203， 本发明的基板 可以是玻璃基板石英基板或者有机基板中的一种。 在两个基板上还设有产生 偏振光的偏光片， 偏光片紧贴在基板上。 其中， 第一基板 202上远离液晶层 的面设有第一偏光片 201， 第二基板 204上设有第二偏光片 205， 为了给液晶 分子一个预倾角， 优选地， 在所述液晶层和基板之间形成取向层， 其中， 取 向层优选采用 PI (聚酰亚胺） 材料， 当给液晶分子一个预倾角时， 有助于液 晶分子的旋转， 遥常预倾角可在 0-2° 范围内。
其中， 偏光控制单元 100包括第三基板 101、 栅线 102、 保护层 103、 第 一电极 104、 隔垫物 105、 第二电极 107和四分之一波片 108， 所述第二电极 107设置在第一偏光片 201上， 所述第二电极 107上依次设有隔垫物 105、第 一电极 104、 保护层 103和第三基板 101 , 所述第三基板 101 上还设有栅线 102 , 所述第≡基板 101在远离保护层的一侧还设有四分之一波片 108。 该第 一电极 107和第二电极 104由透明导电材料形成， 例如 ITO (氧化铜锡）， 可 以是通过溅射的方式形成。 该电极可以设置成预定间隔的条状。
本发明的液晶显示单元 200可以采用现有的液晶显示器， 其中， 第一基 板为 LCD中的彩膜基板， 由于 LCD的出射光线经由彩膜基板射出， 为此， 在彩膜基板一侧设置偏光控制单元。 由于彩膜基板上具有黑矩阵和刻蚀形成 的过孔， 无需在偏光控制单元进行曝光、 显影、 刻蚀、 剥离等步骤。 由于 OC (平坦层） 的透过率较高， 可以作为修补偏光片表面及周边可能会存在的一 些缺陷的材料， 因此优选在所述第一基板之上的第一偏光片上形成平坦层 106， 使得第一偏光片 201具有一平坦的表面。
本实施方式的隔垫物 105设置在第一电极和第二电极之间，形成隔离层， 隔垫物 105可以是柱状、 三角形或者其他合适的形状， 采用的材质可以为树 脂材料。 第≡基板 101 上还设有栅线 102, 该栅线分别与第一电极和第二电 极相连接， 用于向两个电极施加控制信号， 从而控制光线的出射状态。 第三 基板 101在远离电极的一侧设有四分之一波片 108， 该四分之一波片 108是 由双折射单晶薄片组成， 当光法向入射透过时， 寻常光 （0光） 和非常光 （e 光） 之间的位相差等于 π/2或其奇数信。 当线偏振光垂直入射 1/4波片,并—且. 光的偏振和云母的光轴面（垂直自然裂开面）成 Θ角， 出射后成橢圆偏振光。 当 θ:::45°时， 出射光为圆偏振光， 遥过四分之一波片来实现 3D显示。
本发明的立体显示装置将液晶显示单元的基板作为偏光控制单元的其中 一个基板， 省掉了偏光控制单元中周边黑矩阵的刻蚀， 节省了原料， 降低了 成本； 通过直接在液晶显示单元的基板外侧设置电极等部件， 可节省一张基 板， 避免了贴盒胶的使用， 使得立体显示成本大大降低。 另外， 由于本发明 的立体显示装置不存在的对盒贴合的过程， 降低了调试时间， 同时使得贴附 公差减小。
如图 3所示，为本发明一实施方式的立体显示装置的制造方法的流程图， 包括如下歩骤：
歩骤 SI 01 : 提供一液晶显示单元， 所述液晶显示单元包括第一偏光片、 第一基板、 第二基板和设置在两个基板之间的液晶层， 所述第一偏光片位于 第一基板远离液晶层的面上；
步骤 S102: 在所述第一偏光片远离第一基板的面上形成第二电极； 步骤 S103: 提供一第三基板；
步骤 S104: 在所述第三基板的一侧上依次设置栅线、 保护层、 电极和隔 垫物；
步骤 S105: 将所述第三基板上设置隔垫物的面安装在所述液晶显示单元 的第一偏光片上；
步骤 S106: 在第三基板的另一侧上设置四分之一波片。
本发明的立体显示装置的制造方法将液晶显示单元的基板作为偏光控制 单元的其中一个基板， 省掉了偏光控制单元中周边黑矩阵的刻蚀， 节省了原 料， 降低了成本； 通过直接在液晶显示单元的基板外侧设置电极等部件， 可 节省一张基板， 避免了贴盒胶的使用， 使得立体显示成本大大降低。 另外， 由于本发明的立体显示装置不存在对盒贴合的过程， 降低了调试时间， 同时 使得贴 ^公差减小。
本发明的显示单元为现有的各种液晶显示器， 包括第一基板、 第二基板 和设置在两个基板之间的液晶层， 该显示器还包括设置在两个基板外侧的偏 光片， 第一基板上远离液晶层的面设有第一偏光片， 第二基板上设有第二偏 光片。 本发明的基板可以包括玻璃基板、 石英基板或者有机基板中的一种。 液晶显示器为现有技术， 具体制作过程和结构不再赘述。
歩骤 SI02中，在所述第一基板上形成电极，该电极由透明导电材料形成， 例如 ITO (氧化铟锡）， 所述电极层是通过溅射的方式形成的。 该电极可以设 置成预定间隔的条状。 其中， 第一基板为 LCD中的彩膜基板， 由于 LCD的 出射光线经由彩膜基板射出， 为此， 在彩膜基板一侧设置偏光控制单元。 由 于彩膜基板上具有黑矩阵和刻蚀形成的过孔，无需在偏光控制单元进行曝光、 显影、 刻蚀、 剥离等步骤。
优选地， 在步骤 S102之后还包括： 在所述第一基板之上的第一偏光片上 形成平坦层， 使得第一偏光片具有一平坦的表面。

歩骤 SI04中， 在所述第三基板的一面上依次设置栅线、 保护层、 电极和 隔垫物， 在第三基板的一面设置栅线， 栅线与电极相连接， 用于向电极施加 控制信号。 在栅线上设有保护层， 以及在保护层上设置电极和在保护层上设 置隔垫物， 该电极可以设置成预定间隔的条状， 并且可以与第一基板上的电 极成一夹角。
步骤 S105中，将所述第三基板上设置隔垫物的面安装在所述液晶显示单 元的第一偏光片上， 使得所述第三基板安装在液晶显示单元， 并使得隔垫物 朝向液晶显示单元的第一基板， 实现液晶显示单元和偏光控制单元的结合。 由于没有采用贴合胶以及进行对准的步骤， 使得操作简单， 降低了调试时间， 同时使得贴^公差减小。
步骤 S106中， 在第三基板的另一侧上设置四分之一波片， 此时完成了立 体显示装置的制造。

如图 5所示，为本发明一实施方式提供的在液晶显示单元操作的示意图， 在所述第一基板之上的偏光片 201 上形成平坦层 106， 使得第一偏光片 201 具有一平坦的表面。 然后， 在该平坦层 106上形成第二电极 107。

上述技术方案将液晶显示单元的基板作为偏光控制单元的其中一个基 板， 省掉了偏光控制单元中周边黑矩阵的刻蚀， 节省了原料， 降低了成本； 通过直接在液晶显示单元的基板外侧设置电极等部件， 可节省一张基板， 避 免了贴盒胶的使用， 使得立体显示成本大大降低。 另外， 由于本发明的立体 显示装置不存在的对盒贴合的过程， 降低了调试时间， 同时使得贴附公差减 小。
