Surface stabilized ferroelectric liquid crystal (SSFLC) is a widely used technique and expecting solution for the next generation of LC displays, but the appearance of alignment defects knock down the practicability.

In the series of diluted pitch mixtures, the contrast and alignment are better than pure compound in pre-made cells. In particular, the 70% R3206 mixture showed the best result with low driving voltage below 5V and fast response time (τon +τoff) under 1.1 ms. The horizontal chevron defects can be suppressed by asymmetrical hybrid alignment cell structure and greatly improved the contrast ratio of R3026-70 from 68 to the best result of 750. These results provide promising FLC materials with low driving voltage, clean aligned, and fast switching for TFT-LCD application. Huang-Ming Philip Chen 陳皇銘 2007 學位論文 ; thesis 57 zh-TW |

碩士 === 國立交通大學 === 顯示科技研究所 === 95 === Fast switching LCD technology is necessary for achieving high quality of dynamic image.

Surface stabilized ferroelectric liquid crystal (SSFLC) is a widely used technique and expecting solution for the next generation of LC displays, but the appearance of alignment defects knock down the practicability.
Poor alignment issue of R3206 was overcome by the diluted pitch of R3206 mixtures and assembled in asymmetric hybrid alignment cells. In the series of diluted pitch mixtures, the contrast and alignment are better than pure compound in pre-made cells.
