Latest Patents

One of Cho's latest patents is an optical sheet module consisting of optical sheets having different thicknesses. This module includes a first base film that transmits light from its lower portion through its upper portion. It features an upper optical sheet with a first structural pattern that protrudes upwardly, decreasing in cross-sectional area toward the upper portion. Additionally, a second base film is laminated beneath the upper optical sheet, allowing light transmission, while a lower optical sheet with a second structural pattern also protrudes toward the upper optical sheet. The design ensures that the first base film is relatively thicker than the second base film.

Another notable patent is for a flexible display device. This device comprises a base film, a display sheet formed over the base film, and a structural pattern located below the base film. The structural pattern is designed to move the neutral plane concerning the bending stress applied to the display sheet, minimizing stress on layers with a relatively low rupture point. This innovation enhances the durability and performance of flexible display devices.
