A New Method for Liquid Crystal Cells Twist Angle and Cell Gap Measurement
نویسندگان
چکیده
A new simple, fast and accurate method for liquid crystal cell twist angle and cell gap measurement was demonstrated. It is based on a real time spectral measurement of the linear polarization preservation modes. Prior knowledge of the twist angle or director orientations is not required. This method is straight forward and does not require complicated calculations or curve fitting. This system can be easily implemented in commercial instruments.

The optical properties of a (0, 2π) transmissive BTN LC cell is optimized by parameter space method. Experimentally the high contrast ratios above 80 within -80° to 80° viewing angle ranges were first obtained. The highest contrast ratio is 250. The large d∆n makes this new BTN large cell gap and low operating voltage possibility. Introduction Bistable twisted nematic (BTN) liquid crystal displ...

Pretilt angle is a parameter of the utmost importance in the ultimate performance of vertically-aligned negative nematic LC displays. When these devices work in reflective mode, as is the LCOS microdisplays, accurate measurement of pretilt angles becomes a difficult problem, since usual experimental setups based on retardation of the polarization components of the impinging light are proportion...
