" IBM's latest Flat Panel Displays:
A Journey from Science to Technology"
Mahesh G. Samant
IBM Almaden Research Center,
San Jose

At the heart of a liquid crystal flat panel display
is a thin liquid crystal layer with molecules physically aligned along a particular direction. Today this alignment is magically achieved by "rubbing" of a polymer film which typically is a 500 Angstrom thick film of polyimide. The alignment of liquid crystals on a rubbed surface was discovered almost 100 years ago yet the alignment mechanism is not well understood. This lack of any understanding had made the further development of this technology very difficult. Using polarization-dependent, surface-sensitive, near-edge x-ray absorption fine structure (NEXAFS) measurements we discovered what causes these liquid crystal molecules to align. This understanding allowed us to develop a novel non-contact alignment process. This new process uses ion beam irradiation to create alignment layer and is much cheaper and simpler. This process has been demonstrated to be commercially viable.
