本发明涉及液晶显示器技术领域，特别涉及一种纸白型反射式宽视角液晶显示器及其关键工艺。
背景技术
液晶显示器是一种被广泛应用的平面显示器，具有功耗低、外形薄、重量轻以及驱动电压低等特征。液晶显示器本身不能发光，依靠调制外界光实现显示。常规液晶显示方式有适合低路数驱动的TN显示模式、适合高路数驱动的STN显示模式和高对比度的VA显示模式。TN液晶显示器颜色较白，只能低路数驱动；FSTN液晶显示器适合高路数驱动，颜色偏黄或偏蓝；纸白型FSTN液晶显示器可以高路数驱动使用，颜色纸白，但视角较窄。

一种纸白型反射式宽视角液晶显示器，所述的液晶显示器包括上ITO玻璃、下ITO玻璃、液晶、上偏光片、下偏光片和边框，所述的液晶嵌于边框内，液晶上下两面分别设置一片ITO玻璃：上ITO玻璃和下ITO玻璃，所述的上偏光片设置于上部的上ITO玻璃上侧，下偏光片设置于下部的下ITO玻璃下侧。
本发明的特点在于：在所述的上偏光片的下部至上而下依次贴有两层补偿膜：第一层补偿膜和第二层补偿膜；并且，第一层补偿膜和第二层补偿膜之间的补偿夹角为45°，第一层补偿膜与上偏光片的补偿夹角为90°。
进一步地，所述的液晶显示器为STN模式的液晶显示器。
进一步地，所述的液晶显示器为FSTN模式的液晶显示器。
所述的一种纸白型反射式宽视角液晶显示器的关键工艺，包括如下：
1)使用STN制作技术和生产设备；
2)STN模式的液晶显示器颜色均匀；
3)FSTN模式的液晶显示器颜色纸白，色度均匀、没有色差；
4)上偏光片使用包含两层补偿膜的复合膜偏光片，液晶显示器视角宽。
与现有技术相比，本发明的有益效果是：
利用了两层补偿膜匹配的光学补偿性，与液晶匹配，达到对STN的颜色和视角的双重补偿作用，使产品外观颜色纸白，显示视角宽。

具体实施方式
以下结合附图对本发明提供的具体实施方式进行详细说明。
如图1-2所示，一种纸白型反射式宽视角液晶显示器，所述的液晶显示器包括上ITO玻璃4、下ITO玻璃7、液晶6、上偏光片1、下偏光片8和边框5，所述的液晶6嵌于边框5内，液晶6上下两面分别设置一片ITO玻璃：上ITO玻璃4和下ITO玻璃7，所述的上偏光片1设置于上部的上ITO玻璃4上侧，下偏光片8设置于下部的下ITO玻璃7下侧。
本发明的特点在于：在所述的上偏光片1的下部至上而下依次贴有两层补偿膜：第一层补偿膜2和第二层补偿膜3；并且，第一层补偿膜2和第二层补偿膜3之间的补偿夹角为45°，第一层补偿膜2与上偏光片1的补偿夹角为90°。液晶层的光程差为△n*d＝840nm。
所述的液晶显示器为STN模式的液晶显示器。
所述的液晶显示器为FSTN模式的液晶显示器。
所述的一种纸白型反射式宽视角液晶显示器的关键工艺，包括如下：
1)STN模式的液晶显示器(LCD部分，即液晶6、ITO玻璃4和7及边框4)底色均匀；
2)FSTN模式的液晶显示器颜色纸白，色度均匀、没有色差；
3)上偏光片1使用包含双层补偿膜的复合膜偏光片，显示视角宽；
4)下偏光片8为反射型，正显模式贴片。
纸白型反射式宽视角液晶显示器主要有以下特性：

②无电压时：光经过上偏光片1时P光被吸收，S光穿过上偏光片1，再穿过两层补偿膜2和3后，变为R旋光，R旋光穿过液晶6后变为P光，遇下偏光片8被反射，再次穿过液晶6后变为Z旋光，然后再次穿过两层补偿膜3和2后变为S光，S光透过上偏光片1，呈现纸白效果。
以上实施例在以本发明技术方案为前提下进行实施，给出了详细的实施方式和具体的操作过程，但本发明的保护范围不限于上述的实施例。上述实施例中所用方法如无特别说明均为常规方法。
