Hermaphroditic liquid-crystal microlens.
We demonstrate a flat microlens that exhibits hermaphroditic focusing properties. When the input polarization is parallel (perpendicular) to the liquid-crystal directors, the lens exhibits a positive (negative) focal length. To select the proper polarization, we could rotate the polarizer (or the lens) mechanically or by use of an electrically controlled twisted nematic liquid-crystal cell. Det...
متن کاملFast-Response Liquid Crystal Microlens
Electrically tunable liquid crystal microlenses have attracted strong research attention due to their advantages of tunable focusing, voltage actuation, low power consumption, simple fabrication, compact structure, and good stability. They are expected to be essential optical devices with widespread applications. However, the slow response time of nematic liquid crystal (LC) microlenses has bee...
متن کاملEffects of low polymer content in a liquid-crystal microlens.
A small number of bifunctional monomers are mixed with a nematic liquid crystal (LC) and cured with a distributed electric field, which is produced by a circular-hole-patterned electrode structure. A gradient type of lens, that is, a LC microlens, is investigated for various polymer concentrations. Addition of 3% polymer is enough to freeze the gradient-index properties of the structure in the ...
متن کاملPolarizer-free liquid crystal display with double microlens array layers and polarization-controlling liquid crystal layer.
We propose a polarizer-free liquid crystal display (LCD) consisting of two microlens array (MLA) layers, a twisted nematic (TN) LC layer, and two light-blocking masks. By changing the polarization state, focal length of the LCD can be controlled. Since two light-blocking masks have a circular stop pattern and a complementary open pattern, entire gray-scale spectrum may be realized by controllin...
متن کاملSwitchable 2D/3D Display – Solid Phase Liquid Crystal Microlens Array
A new solid phase liquid crystal microlens array has been applied to Polarisation Activated Microlens flat panel displays that can be electrically reconfigured between a full performance 2D mode and a low cross talk autostereoscopic 3D mode. The solid phase microlens array enables significant reductions in device thickness and improved ruggedness compared to nematic phase liquid crystalline mic...
