| Summary: | 碩士 === 國立交通大學 === 光電工程研究所 === 85 === The purpose of this thesis is to simulate the director field distribution of one conic cavity in conic closed-cavity liquid crystal display (CCLCD) so as to calculate the optical transnmittance at any angle of incident light of CCLCD. By using the results of the simulation, we can evaluate the characteristics of the viewing-angle of CCLCD.
The simulation of director distribution will be based on the tensorial form formulation of the free energy density. The differential equations satisfied with the steady-state director distribution are derived from this form of free energy and are solved in conjuction with the Poisson''s equation. The simulation of the optical propogation and the calculation of the optical
transmittance will be based on the extended Jones matrix method. The results of the simulation and the experimentation by Yih-Feng Wang both show that indeed CCLCD can have a wide viewing-angle and can have gray levels but no gray-scale inversion.
