Abstract
To obtain high transmittance and reflectance simultaneously, a single
cell gap transflective liquid crystal (LC) display using internal wire grid
polarizer (WGP) is proposed. For the reflective mode, the imbedded WGP serves
as a polarization-dependent reflector
for the ambient light. For the transmissive mode, no achromatic quarter-wave
film is needed. This device can be used as a normally black mode (using vertical
alignment) and a normally white mode (using twist-nematic alignment), based
on the initial LC cell alignment. Detailed electro-optic performance, such
as voltage-dependent light efficiency and viewing angle of these two device
configurations, is investigated.
