Three-terminal bistable twisted nematic liquid crystal displays
نویسندگان
چکیده
A three-terminal bistable twisted nematic liquid crystal display has been demonstrated. This display makes use of a combination of strong in-plane electric fields and vertical electric field for switching between the f and the f1p twist states. The lifetimes of the two bistable twist states are infinite, which is a significant improvement over conventional bistable twisted nematic displays. © 2000 American Institute of Physics. @S0003-6951~00!00248-5#

Optimization of reflective bistable twisted nematic displays with retardation compensation
The contrast ratios of reflective bistable twisted nematic liquid crystal displays with a rear quarter-wave film are optimized by means of a parameter space approach. By plotting the contrast ratio as a function of the twist angle and thickness-birefringence product (dDn) of the display, the regions where the displays show the best contrast ratio are clearly shown. Both the absolute reflectance...
متن کامل51.1: Invited Paper: Bistable LCDs based on a New Alignment Technology
Several new nematic bistable liquid crystal displays based on a new alignment surface have been demonstrated. Nano-textured alignment surfaces enable the generation of arbitrary pretilt angles and arbitrary anchoring energy. Based on such surfaces, three types of bistable devices have been developed. They are bistable bend-splay, bistable twist-twist and bistable bend-twisted displays.

The brightness and contrast ratio of bistable twisted nematic displays are studied using the parameter space approach. By plotting the contrast ratio as a function of the twist angle and birefringence of the display, regions where the bistable twisted nematic display shows the best contrast ratio are clearly shown. We also studied the switching mechanisms of such displays.
متن کاملOptically optimized transmittive and reflective bistable twisted nematic liquid crystal displays
A new Mueller matrix approach is developed for the design of optical modes for all nematic liquid crystal displays ~LCD!. In particular, for linearly polarized light going into the LC cell, conditions for linear polarization and circular polarization outputs are obtained. By considering the switching between different polarization modes, new transmittive and reflective bistable twisted nematic ...
