Wide Viewing Angle Multi-domain In-Plane Switching LCD

Wide Viewing Angle Multi-domain In-Plane Switching LCD

The bending angle effect on a multi-domain in-plane switching liquid crystal display (MD IPS LCD) using the chevron-shaped electrodes is investigated through a three-dimensional simulation. We find that when the bending angle of the electrodes increases from 10 to 40 , the threshold voltage is lowered from 1.25 Vrms to 0.75 Vrms. With the optimized uniaxial compensation films, the viewing angle...

Wide-viewing angle in-plane switching liquid crystal displays for television applications using optical compensation technology

bstract. Viewing angle performance in in-plane switching liquid rystal displays (IPS-LCDs) has been greatly improved, using two echnologies. One is optical compensation technology using a biaxal film. The other is a newly developed IPS-Pro cell structure with igher transmission efficiency. These technologies are successfully ntroduced into the fabrication of 32-in. IPS-LCDs with a minimum ontra...

Broadband wide-angle polarization converter for LCD backlight.

A novel polarization converter using reflective metallic gratings and a polarization beam splitter is introduced for LCD backlight illumination. These two optical elements form a polarization rotation resonator. Broadband and high optical efficiency of polarization conversion in the visible region is achieved through the resonance of the refracted light and the surface plasmon wave in metallic ...

Vitreoretinal instruments: vitrectomy cutters, endoillumination and wide-angle viewing systems

There have been many advances in vitreoretinal surgery since Machemer introduced the concept of pars plana vitrectomy, in 1971. Of particular interest are the changes in the vitrectomy cutters, their fluidics interaction, the wide-angle viewing systems and the evolution of endoillumination through the past decade and notably in the last few years. The indications of 27-gauge surgery have expand...
