We demonstrated a continuous viewing angle controllable liquid crystal display (LCD) adopting a thermally variable retardation layer (TVRL) using nematic liquid crystal with transparent electric-heating lines to control temperature. The simulated and experimental results of the proposed LCD show continuous and symmetric viewing angle characteristics by tuning the retardation of TVRL using Joule...

A new TN-ECB mode liquid crystal display is developed for reflective liquid crystal displays (RLCDs). This new TN-ECB mode has a larger cell gap and lower operating voltage than most recently developed RLCDs. It also has a small wavelength dispersion and has a good dark state at the low operating voltage. It is particularly suitable for reflective crystalline Si backplane CMOS AMLCDs.

Liquid crystal (LC) based photonic devices are important in light modulated applications including amplitude modulation and phase modulation. [Yang et al. (2006)] The anisotropic properties of LC result in employing two polarizers in most of LC devices. The optical efficiency (~3%) and the viewing angle are limited. Therefore, it is highly desirable to develop polarizer-free LC devices. [Yang e...

Cell gap thickness is one of the most important design parameters for liquid crystal displays ~LCD!. Existing measurement methods only apply to transmittive LC cells. These methods are obviously unsuitable for measuring the cell gaps of reflective LCDs with internal reflectors. This kind of LCD includes single polarizer reflective displays and liquid crystal on silicon displays. The objective o...
