Four-Domain Twisted Nematic Liquid Crystal Display Fabricated by Reverse Rubbed Polyimide Process

we proposed a particularly simple four-domain ͑4-D͒ twisted nematic͑TN͒ liquid crystal display͑LCD͒ device, which is composed of two left-handed and two right-handed TN subpixels. The two members of each pair of same handedness subpixels are rotated 180° with respect to each other, resulting in four domains that spatially average one another optically to provide a wide angle of viewing with no gray s...

Dye-less color filter fabricated by roll-to-roll imprinting for liquid crystal display applications.

A diffractive grating is promising for color separation to effectively replace conventional absorptive dye color filter in liquid crystal displays. In this paper, we demonstrated a color separation module consisting of an aspheric-lenticular lens array and a blazed grating to substitute for the dye color filter. Each component was designed to match the recent fabrication ability of our roll-to-...

Ferroelectric Liquid Crystal Dammann Grating by Patterned Photoalignment

In this article, a ferroelectric liquid crystal (FLC) dammann grating (DG) is demonstrated based on the patterned photoalignment technology. By applying low electric field (10 V) on the FLC DG, the grating can switch between a diffractive state with 7 × 7 optical spots array and a non-diffractive state, depending on the polarity of electric field. The FLC DG shows very fast switching speed with...

Liquid Crystal Display: Environment & Technology

Liquid Crystal Display (LCD) technology has rapidly become a significant component of modern electronics. It offers solution to the rising need of low power-consuming, space-saving and better display devices thereby, paving the way for significant economic opportunities. However, the environmental impact of the end of life of the LCD products should be judiciously assessed, so that they do not ...
