A New BTN LCD with High Contrast Ratio and Large Cell Gap
The optical properties of a (0, 2π) transmissive BTN LC cell is optimized by parameter space method. Experimentally the high contrast ratios above 80 within -80° to 80° viewing angle ranges were first obtained. The highest contrast ratio is 250. The large d∆n makes this new BTN large cell gap and low operating voltage possibility. Introduction Bistable twisted nematic (BTN) liquid crystal displ...
متن کاملNovel Photoaligned Twisted Nematic Liquid Crystal Cell
A novel photoaligned twisted nematic liquid crystal display (TN-LCD) cell is fabricated by one-step illumination with oblique nonpolarized UV light of an empty cell with azo-dye layers coated on indium tin oxide (ITO) substrates. If the incident angle is sufficiently large (>75 ), the p-polarization of the light is more pronounced for the bottom azo-dye layer in comparison with that for the upp...
متن کاملP-130: Large-Cell-Gap Bistable TN-LCD Based on Dual-Frequency Operation
A bistable twisted nematic liquid crystal display based on dual frequency driving electronics has been demonstrated. By using special combinations of alignment layers and liquid crystals, bistability can be achieved readily with cell gaps as large as 5μm.
متن کاملP-156: Transflective Double Cell TN Liquid Crystal Display
Double cell Twisted Nematic (DTN) liquid crystal display is optimized for transflective liquid crystal displays, using MOUSE-LCD software. Two configurations of such DTN-LCD were simulated using a double and a single cell gap approach. DTN-LCD exhibits a high contrast ratio, wide viewing angles and achromatic (black/white) switching in both the transmissive mode and reflective mode. It also pos...
متن کاملHigh Performance Transmittive Bistable Twisted Nematic Liquid Displays
Several new transmittive bistable twisted nematic liquid display (BTN-LCD) modes are developed. Unlike previous versions, these BTN modes do not require cross polarizers. Experiments confirmed that these modes have high contrast ratio and reasonably high transmittance. The dispersion characteristics of some of these modes are comparable to ordinary waveguiding TN modes. That is, they afford tru...
