Plasmonic Color Switching by a Combination Device with Nematic Liquid Crystals and a Silver Nanocube Monolayer.

We experimentally demonstrated electrical plasmonic color modulation by combining a nematic-phase liquid crystal (LC) layer and a silver nanocube (AgNC) monolayer. The color modulation LC/AgNC device was fabricated by filling LCs with negative dielectric anisotropy onto a densely assembled AgNC monolayer. The transmitted light color through the LC/AgNC device was modulated between green and magenta by applying voltages of 0-15 V.

Thin mini-LED backlight using reflective mirror dots with high luminance uniformity for mobile LCDs.

A new mini light-emitting diode (mini-LED) backlight with reflective dots is proposed for high luminance uniformity, high contrast ratio, and low power consumption for use in mobile liquid crystal displays. The proposed backlight, comprising a small number of mini-LEDs, was verified as having high luminance uniformity and high light use efficiency, due to the optimized reflective dots, backlight thickness and light distribution of the mini-LEDs. Moreover, the light leakage to adjacent segments was reduced by cutting a slit between each segment, improving the light use efficiency per segment and suppressing halo artifacts.

Light distribution control of layer-structured PDLC fabricated by using micro lens structure and anisotropically diffused UV light.

We have established a method to control the polymer aggregation structure of the PDLCs by using a micro-lens structure and irradiating them with uni-directionally diffused UV light. The micro-lens structure on the surface of the substrate produced an uneven illuminance distribution of UV light in the LC-monomer mixture, and the monomer was polymerized along the direction of UV light irradiation at positions where the UV illuminance was high and formed a layered structure. The proposed PDLCs could control the light diffusion distribution by the internal polymer aggregation structure and had a high diffusion efficiency without polarization dependency in the haze value.

Diffraction mechanism of a light-diffusing film with an alternate-polymer-layer structure.

A diffraction mechanism, and an optical model to reflect that mechanism, for a light-diffusing film with an alternate-polymer-layer structure was proposed and validated. According to this model, the film forms an angular distribution of light intensity that is almost constant in a certain scattering-angle (cutoff angle) range and drastically decreases outside that range; that is, the profile is similar to a trapezoid. Although the trapezoid intensity distribution (TID) is a fundamental distribution of the film, the mechanism to form the TID has not previously been clarified.

The relationship between spatial cognition and walking trajectory for passing through a doorway: evident in individuals with dominant right eye?

When individuals attempt to walk through the center of a doorway (i.e., spatial bisection), the body's midpoint at crossing can deviate from its true center.
