View Angle Characters of the Chiral HAN-Mode LCD


Article Preview

Calculation of the LCD director and transmission based on the continuous elastic theory, difference iterative method, and the Berreman’s 4×4 matrix method is shown. The realization of this procedure is in Visual C + +. We made a Visual C + + and Matlab interface to achieve the call of the required function out of Matlab. In the case of TN-type LCD, the software has been validated to be correct and reliable. The chiral HAN-mode was described by our laboratory which characteristics were not clear. Transmission has been calculated by using the software with different parameters. The results of the contrast - viewing angle curves show that: the chiral HAN-mode liquid crystal display can achieve wide prospective. We found the optimal setting parameters: Δnd = 0.48μm, p0 = 5 μm, any wavelength of visible light, and the polarizer angle =90° to achieve wide prospective from -85 ° to 85° in the horizontal direction.
