Latest Patents
One of Hyun-Sik Lee's latest patents involves a liquid crystal display having a modified electrode array. This innovative design features electrodes on a single substrate. A transparent planar electrode, elongated in the transverse direction, is formed on the inner surface of the substrate, with an insulating film deposited on top. A plurality of linear electrodes, which can be either transparent or opaque, are formed on the insulating film and elongated in the longitudinal direction. The potential difference between the planar and linear electrodes, generated by applying voltages, creates an electric field. This electric field is symmetrical with respect to the longitudinal central line of the linear electrodes and has parabolic or semi-elliptical lines of force centered on the boundary line between the planar and linear electrodes. The line of force has both vertical and horizontal components, causing the liquid crystal molecules to rearrange, resulting in a twist angle and a tilt angle. Consequently, the polarization of the incident light varies due to the rearrangement of the liquid crystal molecules.
