Abstract
By controlling the deposition time of indium–tin–oxide (ITO) film, a high resistance of ultra-thin ITO (UTITO) layer can be realized. The UTITO layer is then deposited at the interface between the dielectric and LC layers in the hole-patterned liquid crystal (LC) lens. The UTITO application spreads the fringing field into the aperture hole center of LC lens and thus assists the LC reorientation therein. That considerably decreases the addressing voltage and switching-on time of LC lens. The UTITO LC lens also provides a wide tunable focus function, and preserves the lens quality and imaging performance as the conventional hole-patterned LC lens.
