Low driving voltage FLC material, R3206 with Vsat. at 3.5 V (AZ Electronic Materials), and its mixtures were under evaluation for potential TFT display application. Poor alignment issue was overcome by the diluted pitch mixtures and asymmetric hybrid alignment cells. In the series of diluted pitch mixtures, the contrast and alignment are better than pure compound in pre-made cells (1.8±0.1μm, from EHC). In particular, the 70% R3206 mixture showed the best result with low driving voltage below 5 V and fast response time (Τ on + Τ off) under 1.1 ms. The hybrid alignment cell was successfully suppressed horizontal chevron defects and achieved the best contrast ratio of 750. These results provide promising FLC materials with low driving voltage, well aligned, and fast switching for TFT-LCD application.
