本发明实施例提供的半透半反液晶显示装置的工作原理如下：
外部光线 50 为日光或灯光等从半透半反液晶显示装置外部照射到像素 单元的光线， 当外部光线 50照射到半透半反液晶显示模组 10上时， 照射到 每个像素单元反射区的外部光线 50作为照射像素单元的光线，照射到每个像 素单元透射区的外部光线 50通过设置在半透半反液晶显示模组 10下方的反 射层 40反射到相邻像素单元透射区内， 提高照射到该像素单元透射区的亮 度， 同时， 通过在背光源 20上的聚光层 30将背光源 20照射出的内部光线 60汇聚， 并通过反射层 40上的网孔 41照射到每个像素单元的透射区。
本发明实施例提供的半透半反液晶显示装置， 照射到每个像素单元透射 区的光线有两个来源， 一个是通过反射层 40反射过来的外部光线 50, 另一 个是汇聚过来的背光源 20照射出的内部光线 60。通过反射层 40和聚光层 30, 增强了每个像素单元透射区的光线亮度， 从而缩小了每个像素单元的透射区 和反射区的亮度差， 提高了半透半反液晶显示装置在强光下的显示效果。
在上述实施例中， 为了使背光源 20照射出的内部光线 60能够较多的汇 聚到每个像素单元的透射区， 例如， 所述每个聚光镜 31的中心线（例如， 聚 光镜的光轴）与对应像素单元的透射区的中心线（例如， 沿垂直于液晶显示 模组的方向穿过透射区的中心线）重合，聚光镜 31与对应像素单元的透射区 中心对应， 使得聚光镜 31汇聚的内部光线 60能够更多的照射到对应像素单 元的透射区。
如图 1和图 3所示， 在上述实施例中， 由于聚光镜 31汇聚的内部光线 60需要穿过反射层 40上的网孔 41 , 因此，为了使聚光镜 31汇聚的内部光线 60能够更多的穿过网孔 41照射到对应像素单元的透射区， 例如， 所述每个 网孔 41的中心线（例如， 沿垂直于反射层的方向穿过网孔的中心线）与对应 聚光镜 31的中心线重合。 此时， 聚光镜 31、 网孔 41以及对应像素单元的透 射区的中心——对应， 从而保证了聚光镜 31汇聚的内部光线 60能够最大限 度的照射到对应像素单元的透射区。 为了进一步提高这一效果， 聚光镜 31 的聚焦点与网孔 41之间的距离以及网孔 41与对应像素单元透射区的距离需 根据生产时的不同的半透半反液晶显示模组 10来确定。
在上述实施例中， 聚光层 30可以为不同材料的聚光层 30, 较佳的为透 明高分子光学膜或玻璃层。 其中透明高分子光学膜可以为聚乙婦膜或聚丙烯 膜。
在上述实施例中， 聚光镜 31可以选择多种， 如三棱镜、 双面凸透镜、 单 面凸透镜等比较常见的聚光镜 31。
在上述实施例中，反射层 40需具有较佳的反射光线的效果， 例如， 所述 反射层 40为金属反射层 40。采用金属反射层 40可以便于反射层 40的制作， 金属反射层 40的网孔 41可以直接沖孔得到， 通过现有的设备以及工艺即可 制作而成， 降低了反射层 40的生产成本。
在上述实施例中，半透半反显示模组 10可以为单盒后的半透半反液晶显 示模组， 也可以为双盒后的半透半反液晶显示模组。 双盒后的半透半反液晶 显示模组 10包括： 对盒的彩膜基板 11和阵列基板 12; 设置在所述彩膜基板 11和阵列基板 12之间的液晶层 13; 设置在所述阵列基板 12面向液晶层 13 一面上的反射层 40; 以及设置在彩膜基板 11面向液晶层 13—面的上取向层 (图中未示出） 以及设置在阵列基板 12面向液晶层 13—面的下取向层（图 中未示出） ， 且所述下取向层位于所述反射层 40的上方。
本发明实施例提供改的半透半反液晶显示装置的制作方法， 包括以下步 骤：
制作聚光层， 聚光层具有多个聚光镜； 制作反射层， 且反射层上具有与聚光镜一一对应的网孔； 将制作好的聚光层固定在背光源上；
将制作好的反射层固定在聚光层上， 并^!射层具有的网格与聚光层的 聚光镜——对应。
本实施例提供的半透半反液晶显示装置的具体制作步骤如下： 一、 制作背光源；
二、 制作半透半反液晶显示模组；
三、 根据半透半反液晶显示模组中像素单元之间的中心间距来确定聚光 镜的中心间距， 使聚光镜与对应的像素单元中心对称；
四、 通过注塑机来制作聚光层；
五、 将制作的聚光层固定设置在背光源上；
六、 通过沖压机制作金属反射层， 在金属反射层上沖出与聚光层对应的 网孔；
七、 将制作好的金属反射层固定在聚光层上， 并使金属反射层的网孔与 聚光镜——对应。
通过上述制作方法制作形成的半透半反液晶显示装置， 在强光下具有较 佳的显示效果。
