With a total of 2 patents, his work showcases innovative methods that enhance the functionality of optical devices.

Latest Patents

One of his latest patents is focused on photo-patterned light polarizing films. This invention relates to methods for preparing photo-patterned mono- or polychromatic polarizing films. The polarizer can be pixelated into a number of small regions, wherein some regions have one orientation of the principal neutral or color absorbing axis, while others have a different orientation. The axis orientation is determined by the polarization vector of actinic radiation, and multi-axes orientation is achievable through a separated masked exposure. This polarizer can be placed on the interior substrate surface of the LCD cell. Another significant patent is the method of manufacturing a photo-alignment layer. This layer has excellent long-term stability to light and heat, manufactured by coating a material containing a dichroic dye with multiple polymerizable groups per molecule on a substrate. The coating layer is then exposed to polarized light, imparting a photo-alignment function, followed by polymerization of the polymerizable groups through heating or light exposure.
