Each company has its own proprietary compounds for mixing to meet desired characteristics. For displays with substantially improved features in certain areas such as speed or brightness, display technology generally looks toward other promising kinds of liquid crystal phases, such as the FLC phase, or toward different kinds of materials, such as PDLCs. The FLC display offers substantially improved switching times and bistability. The latter feature permits the use of the LCD display for a passive matrix with reduced display cost. FLC materials have also not met desired specifications.
Higher resolution requires shorter response.
A preferred FLC material of Dainippon Ink shows a 60-micro sec response time that could be reduced to 29 micro sec with a sacrifice in contrast. The FLC display recently reported by Canon does not exhibit video rates. There is probably more promise in improving the FLCs with new synthesis and molecular design than there is in nematics for TN and STN, because less has been done. A range about the smectic C. Scientists at Fujitsu described how this feature can lead to improved surface stabilization. There is substantial research on FLC compounds in universities and industry around the world.
