Planar structured interfaces, also known as metasurfaces, are continuously attracting interest owing to their ability manipulate fundamental attributes of light, including angular momentum, phase, or polarization. However, chromatic aberration, limiting broadband operation, has remained a challenge for metasurfaces-based optical components and imagers. The limitation stems from the intrinsic dispersion existing materials design principles. Here we report experimentally demonstrate...

Recently, low-frequency driving of liquid crystal display (LCD) panels to minimize power consumption has drawn much attention. In the case in which an LCD panel is driven by a fringe-field at low frequency, image flickering phenomenon occurs when sign applied electric field reversed. We investigated induced flexoelectric effect switching (FFS) cell terms transmittance difference between frames and ripple phenomenon. Experimental results show that flicker due can be eliminated completely...

Conventional optical components have been proposed to realize high-quality line focusing with uniform intensity distribution such as cylindrical lenses, segmented wedge-arrays, or a combination of prisms and spherical mirrors. Numerous factors the manufacturing tolerances need for precise alignment conventional lenses cause wave front aberrations that impact performance systems.

Although the fringe-field-switching (FFS) mode based on a two-domain (2D) electrode structure has been widely used for wide viewing angle in liquid crystal display (LCD), it still suffers from color shift and asymmetric luminance distribution at off-axis. We propose four-domain (4D) characteristics an FFS LCD. demonstrate that use of 4D instead 2D-chevron can reduce off-axis difference 0.038 to 0.010 low gray level 0.019 0.002 mid-gray level. Moreover, gamma distortion is reduced 0.159 0.007.
