Title: Innovations of Woo Sang Park in Liquid Crystal Display Technology.

Introduction

Woo Sang Park is a notable inventor based in Anyang, South Korea. He has made significant contributions to the field of liquid crystal display (LCD) technology. With a total of 3 patents, his work focuses on improving the performance and efficiency of LCDs.

Latest Patents

Among his latest patents are two innovative methods related to orientation films in LCDs. The first patent describes an orientation film of photopolymer in a liquid crystal display. The second patent outlines a method for the formation of this orientation film. This method involves forming a polyvinyl-4-fluorocinnamate (PVCN-F) film on the surfaces of two opposite substrates. The PVCN-F films are then irradiated with linearly polarized UV lights of different energy levels. This innovative approach not only provides a pretilt angle to the fabricated LCD but also allows for adjustment by illuminating the substrates with UV beams of varying energies. The resulting LCD requires a significantly lower driving voltage compared to conventional models. Additionally, it minimizes phase distortion and light scattering, thereby enhancing display characteristics such as contrast. The use of PVCN-F, which is highly resistant to heat, ensures excellent thermostability for the LCDs produced using this method.
