Title: The Innovative Contributions of Kang-Il Seo
Introduction
Kang-Il Seo is a prominent inventor based in Suwon, South Korea. He has made significant contributions to the field of optical technologies, holding a total of 5 patents. His work focuses on enhancing the performance of liquid crystal displays (LCDs) through innovative optical film composites.
Latest Patents
One of Kang-Il Seo's latest patents is an optical film composite for brightness enhancement, which includes a birefringent polymer layer. This invention provides an optical film composite that consists of a linear, reflective polarizing film, a first polymeric substrate layer with birefringence placed on the reflective polarizing film, and a second polymeric substrate layer beneath the reflective polarizing film. The optical axis of the first polymeric substrate layer is oriented with respect to the transmission axis of the reflective polarizing film, allowing for an angular difference between the axes of 0° to 25°. This optical film composite can be employed in LCD devices to improve optical performance.
Another notable patent is for direct-lit liquid crystal displays with laminated diffuser plates. In this invention, a number of light management films, including a diffuser layer, are positioned between the light source and the LCD panel to provide bright and uniform illumination. The diffuser layer can be attached to a separate substrate or directly to the LCD panel or light source. This design achieves high levels of illumination uniformity at the LCD, even with low levels of diffusion, when used in conjunction with a brightness-enhancing layer.
