^图, 对本发明的实施例中的技术方案 进行清楚、 完整地描述, 显然, 所 述的实施例仅仅是本发明的一部分实施 例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普遥技术人员在 没有做出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的 本发明的实施例提供了一种液晶镜片 10, 如图 1所示, 液晶镜片 10包 括液晶盒 100, 所述液晶盒 100包括第一基板 101和第二基板 102、 以及设 置在第一基板和第二基板之间的液晶层 103 ;所述第一基板 101包括第一衬 底基板!011、设置在所述第一衬底基板 1011上的多个晶体管(图中未标出)、 与所述晶体管的其中一个电极电连接的第一电极 (图中未标出)、 以及设置 在所述第一衬底基板 1011远离所述液晶层 103—惻的第一偏光片 1012;所 述第二基板 102 包括第二衬底基板 1021、 以及设置在所述第二衬底基板 1021远离所述液晶层 103—侧的第二偏光片 1022; 所述液晶镜片 10还包 括第二电极 (图中未标出), 所述第二电极设置在所述第一衬底基板 1011 上或第二衬底基板 1021上;其中,所述第一衬底基板 1011和所述第二衬底 基板 1021为不透明; 所述第一衬底基板 1011和所述第二衬底基板 1021均 包括多个小孔 110, 且所述多个小孔 110的位置一一对应。
其中, 对于上述的第一基板 101 , 还可以包括与所述晶体管的源极连接 的数据线, 通过该数据线可以给所述第一电极迸行充电, 并通过第二电极 的共同作用, 实现液晶的偏转。 所述晶体管的一个电极, 根据晶体管的类 型不同, 可以是源极, 也可以是漏极。
对于设置在不透明的第一衬底基板上的晶体管、 第一电极等可以通过 与目前的阵列基板中的晶体管和像素电极相似的工艺制备形成; 在此基础 上, 所述晶体管优选为薄膜晶体管, 这样可以满足薄型化的市场需求。
所述第一衬底基板 1011和所述第二衬底基板 1021 为不透明, 可以是 所述第一衬底基板 1011 和所述第二衬底基板 1021本身的材质为不透明材 质, 从而形成不透明的衬底基板; 也可以是所述第一衬底基板 1011和所述 第二衬底基板 1021本身的材质为透明材质,并在所述透明材质的上 /下表面 设置一层不透明薄膜, 从而形成不透明的衬底基板。
在所述第一衬底基板 1011和所述第二衬底基板 1021 本身的材质为透 明材质, 并在所述透明材质的上 /下表面设置一层不透明薄膜的情况下, 所 述不透明薄膜可以通过涂覆深色例如黑色或茶色油墨、 深色颜料, 或者沉 积深色膜层等方法得到, 在此不作限定。
当自然光入射到所述液晶镜片 10时, 经过入光侧的偏光片的作用将所 述自然光转变为线偏振光进入所述液晶镜片 10; 通过控制所述第一电极和 所述第二电极之间的电压, 可以调节所述液晶层 103中的液晶的偏转角度, 再经过另一个偏光片的作用, 便可达到调节所述液晶镜片的不同小孔 110 中的光透过率的目的,这样便可以根据需要选择透光小孔 110的个数以及位 置。 其中, 入光侧的偏光片可以是第一偏光片 1012, 也可以是第二偏光片 1022。 需要说明的是,第一,所述第一衬底基板 1011和所述第二衬底基板 1021 均包括多个小孔 110, 且所述多个小孔 110的位置一一对应, 是指: 从垂直 所述第一衬底基板 1011和第二衬底基板 1021的方向看过去,位于所述第一 衬底基板 1011上的第一小孔和第二衬底基板 1021上的第二小孔的投影重 叠。
第二, 不对所述小孔 no 的个数进行限定, 其排布位置也可根据实际 需要自行排布。
第三, 所述小孔 110周围可以设置与所述液晶盒 100中的液晶层 103 分隔开的隔离层, 用于防止液晶发生泄漏时从所述小孔 110流出。
第四, 所述第二电极可以设置在所述第二衬底基板 1021上, 这样在所 述第一电极和所述第二电极之间便可以形成垂直电场来控制所述液晶层 103 中液晶的偏转; 当然, 所述第二电极也可以设置在所述第一衬底基板 1011 上, 这样在所述第一电极和所述第二电极之间便可以形成横向电场来 控制所述液晶层 103中液晶的偏转。
本发明的实施例提供了一种液晶镜片 10, 其包括液晶盒 100, 所述液 晶盒 100包括第一基板 101和第二基板 102、以及设置在第一基板和第二基 板之间的液晶层 103 ;所述第一基板 101包括第一衬底基板 1011、设置在所 述第一衬底基板 1011上的多个晶体管、 与所述晶体管的其中一个电极电连 接的第一电极、 以及设置在所述第一衬底基板 101 !远离所述液晶层 103— 侧的第一偏光片!012; 所述第二基板 102包括第二衬底基板 1021、 以及设 置在所述第二衬底基板 1021远离所述液晶层 103—侧的第二偏光片 1022; 所述液晶镜片 10还包括第二电极, 所述第二电极设置在所述第一衬底基板 1011上或第二衬底基板 1021上; 其中, 所述第一衬底基板 1011和所述第 二衬底基板 1021 为不透明; 所述第一衬底基板 10U 和所述第二衬底基板 1021均包括多个小孔, 且所述多个小孔的位置 一对应。
这样, 通过调整所述第一电极和所述第二电极之间的电压, 可以控制 所述液晶层 103中的液晶偏转相应的角度, 调节所述液晶镜片 10的不同小 孔的光透过率, 从而可以根据需要选择透光小孔的个数以及位置; 通过设 置在所述液晶镜片 10上的小孔 110, 可以使图像聚焦在视网膜中心, 从而 看到更加清晰的图像, 同时具有缓解视觉疲劳的功效。
优选的, 如图 2所示, 所述液晶镜片 10还可以包括设置在所述液晶盒 100的至少一个侧表面的薄膜光栅 120; 其中, 所述薄膜光栅 120包括多个 透光区域, 所述多个透光区域与所述多个小孔 no—一对应。
其中, 所述薄膜光栅 120 可以包括透明的光学薄膜、 以及设置在所述 光学薄膜表面的光栅。 这里, 所述光学薄膜优选为高透过率的光学薄膜, 通过采用高透过率的光学薄膜可使经过所述薄膜光栅 !20 的透光区域的光 损耗最小。
这里, 所述液晶盒!00的至少一个侧表面是指所述液晶盒 100中平行 于所述第一基板 101和 /或所述第二基板 102的至少一个侧表面, i所述薄 膜光栅 120 与该至少一个侧表面紧密贴 I 。 这样, 可以根据需要设置所述 透光区域的大小, 从而可以达到改变所述小孔 110的孔径大小的目的。
进一步地, 考虑到在实际使用过程中希望随时改变所述小孔 Π 0 的孔 径大小, 因此, 优选的, 所述光学薄膜的面积小于所述液晶盒 100的面积; 这样便可以通过控制所述薄膜光栅 120相对所述液晶盒 100的移动, 实现 所述薄膜光栅 120的所述多个透光区域相对所述多个小孔 110的移动,从而 达到随时调节所述多个小孔 110的孔径大小的目的。
其中, 当所述薄膜光栅 120的多个透光区域与所述多个小孔 110 -—一 对应, 且所述薄膜光栅 120的透光区域的面积完全包裹着所述小孔 110时, 所述小孔 110的孔径大小即为其原始孔径大小;当所述薄膜光栅 120相对所 述液晶盒 100的表面发生移动时, 所述薄膜光栅 120的透光区域也会发生 相应的移动,此时所述小孔 110的部分面积便会被所述薄膜光栅 120的非透 光区域部分遮挡, 从而减小了所述小孔 110的孔径大小。
这里, 所述光学薄膜的面积小于所述液晶盒 100 的面积是为了保证在 所述薄膜光栅 120相对所述液晶盒 100的表面移动时, 所述薄膜光栅 120 依然贴 Pf†在所述液晶盒 100的表面, 不会超出所述液晶盒 100的边缘而脱 离所述液晶镜片 10。 对于所述光学薄膜的面积, 在此不做限定, 以有利于 调节所述小孔 no的孔径大小为准。
基于此, 优选的, 如图 3所示, 所述液晶镜片 10还可以包括设置在所 述液晶盒 100相对所述薄膜光栅 120—侧的表面上的多个微凸结构 1301, 以及设置在所述光学薄膜相对所述液晶盒 100 —侧的表面上的多个微孔结 构 1302。
或者,如图 4所示,所述液晶镜片 10还可以包括设置在所述液晶盒 100 相对所述薄膜光栅 120—侧的表面上的多个微孔结构 1302, 以及设置在所 述光学薄膜相对所述液晶盒 100—惻的表面上的多个微凸结构 1301。
其中, 所述多个微凸结构〗301和所述多个微孔结构 1302——对应且 互相匹配。
这里, 通过设置在所述液晶盒 100表面的多个微凸结构 1301和设置在 所述光学薄膜表面的多个微孔结构 1302, 或者设置在所述液晶盒 100表面 的多个微孔结构 !302和设置在所述光学薄膜表面的多个微凸结构 1301之 间的相互配合, 可以使所述光学薄膜固定在所述液晶盒 100 表面而不易发 生移动。
示例的, 在所述液晶盒 100相对所述薄膜光栅 120—侧的表面设置多 个微凸结构 1301, 所述光学薄膜相对所述液晶盒 100—侧的表面设置多个 微孔结构 1302, 且所述多个微孔结构 1302和所述多个微凸结构 1301 - 对应且互相匹配的情况下, 当所述薄膜光栅 120 的所述多个透光区域相对 所述多个小孔 no的位置需要调整时,可以首先使所述液晶盒 ioo表面的多 个微凸结构 1301和所述光学薄膜表面的多个微孔结构 1302分离, 随后控 制所述薄膜光栅 120相对所述液晶盒 100相对移动; 当所述薄膜光栅 120 与所述液晶盒 W0之间的相对位置调整完成后, 所述液晶盒 100表面的多 个微凸结构 1301和所述光学薄膜表面的多个微孔结构 1302进行合并, 实 现位置的限定。
进一步优选的, 所述液晶镜片 10的所述多个微凸结构 1301和所述多 个微孔结构!302可以设置在所述液晶镜片 10的一个对角顶点处。
由于设置在所述液晶镜片 10的某一对角顶点处的微凸结构 1301与微 孔结构 1302包含了多组微凸结构与微孔结构,也就是说,所述微凸结构 1301 与微孔结构 1302是由多个微凸结构和多个微孔结构组成的, 且所述多个微 凸结构 1301与所述多个微孔结构 1302之间相互匹配, 因此所述多个微凸 结构 1301和所述多个微孔结构 1302仅需设置在所述液晶镜片 10的一个对 角顶点处即可实现其固定限位作用。
进一歩的, 所述液晶镜片 10还可以包括设置在所述液晶盒 100和所述 薄膜光栅 120之间的透明液体, 所述透明液体用于实现所述液晶盒 100和 所述薄膜光栅 120之间相对位置调整时的润滑与密封。
这里, 所述透明液体可以为无色透明液体, 例如可以是隐形眼镜护理 液。 由于所述透明液体是应用于液晶小孔眼镜中, 因此要求其无毒无害, 以防止所述液晶小孔眼镜发生破损时液体潘漏造成的伤害。
当所述薄膜光栅 120与所述液晶盒 100之间的相对位置进行调整时, 可以依靠所述透明液体的吸附实现二者之间的密封, 从而使得所述薄膜光 栅 120的光学薄膜与所述液晶盒 100之间达到紧密的贴合, 以实现所述小 孔 110孔径的精确调节。
可选的, 所述的液晶镜片 10 的每个小孔 110 的孔径可以设置为 1〜 3m.ni o
由于小孔 镜是基于小孔成像的原理进行工作的, 因此对小孔的孔径 具有一定的要求。 通常情况下, 小孔暖镜中小孔的孔径大小接近正常人在 常态下瞳孔的大小, 其直径大约为 3mm, 但是考虑到小孔的孔径小, 其成 像清楚, 因此这里优选的, 小孔 110的孔径可以设置为 i〜3mm。
可选的, 所述液晶镜片 10的所述多个小孔 110中用于透光的小孔的个 数可以为 3个或 5个。
所述液晶镜片 10处于工作状态^, 以不影响所述液晶镜片 10的观看 效果为前提,可以仅保证部分所述小孔 110透光即可。具体可以通过控制所 述液晶镜片 10中的所述第一电极和所述第二电极之间的电压, 调节所述液 晶层 103 中的液晶进行相应的偏转, 并经过偏光片的作用, 便可达到调节 所述液晶镜片的不同小孔 110中的光透过率的目的,这样便可以根据需要选 择透光小孔 110的个数以及位置。

在此基础上, 首先, 当自然光入射到所述液晶镜片 10时, 经过入光侧 的偏光片例如第一偏光片 1012的作用将所述自然光转变为线偏振光进入所 述液晶镜片 10。
其次, 遥过调节所述液晶镜片 10中的所述第一电极和所述第二电极之 间的电压, 可以控制所述液晶层 103 中的液晶进行相应的偏转, 从而控制 对应不同小孔 no处的液晶的偏转角度,例如可以控制对应所述倒三角形顶 点位置的小孔 n o处的液晶的偏转角度,使通过该处液晶的偏振光经第二偏 光片 1022后完全透过, 控制其他位置的小孔 110处的液晶的偏转角度, 使 通过该处液晶的偏振光经第二偏光片 1022后无法透过, 那么所述液晶镜片 10中处于工作状态的所述小孔 110就仅为所述倒三角形顶点位置的 3个小 孔 110。
这里, 当然, 也可以控制所述液晶层 103 中的液晶进行相应的偏转, 改变所述倒三角形顶点位置的 3个小孔 110的位置。
