Latest Patents

Eun Kyeong Seo’s latest patents reflect his expertise in polarizing plates and their applications in liquid crystal displays. One notable patent describes a polarizing plate that includes a polarizer and at least one protective film. This protective film exhibits an in-plane retardation (Re) of more than 10,000 nm at a wavelength of 550 nm, calculated using the equation Re=(nx−ny)×d. Here, nx and ny are the indices of refraction in the x-axis and y-axis directions, respectively, and d represents the thickness of the protective film.

Another patent from Seo covers a polarizing plate, a method for preparing it, and an optical display apparatus that includes the same. The design features a polarizer with distinct absorption and transmission axes, a protective film on the upper surface, a half-wavelength (λ/2) retardation film on the lower surface, and a quarter-wavelength (λ/4) retardation film under the adhesive layer. This configuration allows for minimal orthogonal b-coordinate values when paired with a reference polarizing plate, optimizing the polarizing plate's performance in display applications.
