摘要

In plane switching (IPS)-mode liquid crystal display (LCD) is one of the most useful technologies for a wide range of viewing angles. For IPS-mode application, we synthesized novel diamine containing a methyl group as a bridge and homogeneous alignment materials. A 1∼ 2 low pretilt angle manifested by changing dianhydrides (BTDA and BPDA) and bridged diamines (ODA and PACM). We measured their pretilt angles using the ...
