“…3. Thickness value in the final manufactured LC lenticular arrays has been increased by 30%, providing the devices with the additional space to d = 50 μm, as in previous results reported in this subject [23]. We have reported bigger focal lengths than expected according to theoretical values, attri− buting this effect to the saturation in the tilt angle of the mo− lecules as switching, thus, diminishing the effective birefringence inside the device.…”

“…Liquid crystals (LCs) are self-organized anisotropic fluids, well-known for their use in flat panel mobile, PC, and TV displays. Besides consumer electronic products, LCs are employed in many photonic devices such as spatial light modulators, beam steerers, and tunable lenses and filters [ 3 – 4 ]. LCs are usually confined into thin (few µm) cells, where an adequate conditioning of the inner cell surfaces leads to long-range orientational order [ 5 ], represented by a vector called the director.…”

SummarySingle-wall carbon nanotubes (SWCNT) are anisotropic nanoparticles that can cause modifications in the electrical and electro-optical properties of liquid crystals. The control of the SWCNT concentration, distribution and reorientation in such self-organized fluids allows for the possibility of tuning the liquid crystal properties. The alignment and reorientation of CNTs are studied in a system where the liquid crystal orientation effect has been isolated. Complementary studies including Raman spectroscopy, microscopic inspection and impedance studies were carried out. The results reveal an ordered reorientation of the CNTs induced by an electric field, which does not alter the orientation of the liquid crystal molecules. Moreover, impedance spectroscopy suggests a nonnegligible anchoring force between the CNTs and the liquid crystal molecules.

“…Some recent works have also demonstrated how the inclusion of a Si02 layer could improve the resistivity of the set by several orders of magnitude, produced by the metal-induced crystallization process [25]. We have experimentally observed how these two layers set increases the resistivity exponentially if the thickness of the evaporated nickel is smaller than 7 nm (1-5 Gf2/sq) [10]. In Fig.…”

“…Modal lenses exhibit sometimes some spherical aberration because of the high resistivity of the manufactured layer. However, this aberration can be reduced by increasing the thickness of the layer [10]. We demonstrate how these lenses can work in an autostereoscopic system and validate, for the first time, the proposed system through 3D contrast measurements.…”

Abstract-In recent years, many experimental and theoretical research groups worldwide have actively worked on demonstrating the use of liquid crystals (LCs) as adaptive lenses for image generation, waveform shaping, and non-mechanical focusing applications. In particular, important achievements have concerned the development of alternative solutions for 3D vision. This work focuses on the design and evaluation of the electro-optic response of a LC-based 2D/3D autostereoscopic display prototype. A strategy for achieving 2D/3D vision has been implemented with a cylindrical LC lens array placed in front of a display; this array acts as a lenticular sheet with a tunable focal length by electrically controlling the birefringence. The performance of the 2D/3D device was evaluated in terms of the angular luminance, image deflection, crosstalk, and 3D contrast within a simulated environment. These measurements were performed with characterization equipment for autostereoscopic 3D displays (angular resolution of 0.03°).
