Title: Innovations of Ji Hoon Kim in Polarizing Plate Technology

Introduction

Ji Hoon Kim is a notable inventor based in Hwaseong-si, South Korea. He has made significant contributions to the field of polarizing plate technology, holding 2 patents that enhance the performance and efficiency of display devices.

Latest Patents

His latest patents include a method of preparing a polarizing plate for antireflection. This innovation features a polarizing plate that includes a polarizer and a protective layer formed on at least one surface of the polarizer. The polarizing plate achieves a single transmittance of 44.6% or more and a degree of polarization of 98% or more. It also satisfies specific criteria regarding orthogonal components, ensuring high transmittance while preventing the blue-shift phenomenon and maintaining a neutral reflection color. Additionally, the polarizing plate can be made thinner, which is a significant advantage in display technology.

Another patent focuses on a polarizing plate for antireflection and the display device comprising the same. This invention also includes a polarizer and a protective layer, with similar performance metrics. Notably, the polarizing plate exhibits a shrinkage rate in the stretching direction of 0.5% or less after standing at 85° C. for 240 hours. This innovation is resistant to curling and minimizes bending of the panel after adherence, while also reducing dispersion of reflection color depending on the position.
