| Summary: | 碩士 === 中原大學 === 應用物理研究所 === 97 === Abstract
Liquid crystal display (LCD) is severely requested on the market, and MVA mode is
valued because it’s high contrast. But it has serious color washout in the off axis of MVA
mode in the off axis. In this thesis we analyze the color washout of MVA mode and
compare the various definition of the color washout nowadays and propose a new value
to depict color washout phenomenon (G value). To analyze the influence of LC’s
domains, optical structure and cell gap on color washout in MVA mode by using G value
and 1D LCD MASTER. We find the optimum design with 8-domain MVA technique to
improving color washout.
Finally, we use new driving method for iMVA panel to verify the optimization
searched by using G value of 8-domain technique.
