Title: Threshold Characteristics of Homeotropic-twisted Nematic Liquid Crystal Display
Abstract: Based on Frank continuum theory, the threshold voltage formula of Freedericksz transition in homeotropic twisted nematic mode is deduced in this paper. The threshold voltage is expressed by π k 33 e 0| Δ e|1-4k 22 k 33 2dP 0 2and verified by calculated C V characteristics. The reason that threshold voltage decreases with the increase of d/P 0ratio is also discussed.
