Description

显示面板制作方法及液晶显示器
【技术领域】
本发明涉及显示技术领域，特别是涉及显示面板制作方法及液晶显示器。
【背景技术】
目前，电视用液晶面板（LCD-TV）的显示模式主要采用VA（Vertical Alignment）技术和IPS（In Plane Switching）技术。其中，VA技术包括MVA（Multi-domain Vertical Alignment）技术和PVA（Patterned Vertical Alignment）技术等。这些技术由于突起、缝隙等域分界物的存在而引起开口率低、对比度差、响应速度慢和工艺复杂等问题。
光配向技术主要使用紫外光对光敏感度高、稳定性好的配向材料进行光配向，用其制作的液晶面板不需要域分界物，具有高开口、高对比、快速响应等特性，消除了传统模式所无法克服的缺陷，而日渐成为液晶行业研究的热点。
液晶显示器的配向膜需要进行配向处理才能有效地控制液晶分子的排列，配向技术主要有摩擦（Rubbing）型和非摩擦（Non-Rubbing）型两大类。摩擦配向是在高分子PI表面用绒布滚轮进行接触式的定向机械摩擦，摩擦高分子表面所供的能量使高分子主链因延伸而定向排列，从而控制液晶配向排列。这种方法的优点是在常温下操作，摩擦时间短，量产性高。缺点是PI材料具有高极性、高吸水性，储存或运送时容易变质而造成配向不均匀；摩擦造成的粉尘颗粒、静电残留、刷痕等问题容易降低工艺良率。光配向技术属于非摩擦型配向，其原理是利用紫外光使得光敏聚合物单体材料发生光化学反应产生各向异性，液晶分子与配向膜表面分子相互作用，为了达到能量最小的稳定状态，液晶分子沿着光配向所定义的受力最大的方向排列，提高了光配向产品的整体性能。非摩擦配向可以避免机械摩擦给配向膜带来的不良问题。
