Title: Innovations of Joo-sang Park in Display Technology

Introduction

Joo-sang Park is a notable inventor based in Suwon, South Korea. He has made significant contributions to the field of display technology, particularly in the manufacturing of color filters and plasma display panels. With a total of 3 patents, his work has advanced the quality and efficiency of display devices.

Latest Patents

One of his latest patents is a method for manufacturing a color filter. This innovative method utilizes thermal transfer with a laser beam that has uniform energy distribution. The process involves forming a black matrix pattern on a substrate through photolithography. A transfer film containing thermal color layers is then placed on the substrate, and a laser beam irradiates the film to transfer the color layers onto the substrate. The substrate is subsequently cured at temperatures between 200°C and 300°C. This technique enhances the quality of images formed at the edges and reduces surface roughness, resulting in an excellent color filter.

Another significant patent by Joo-sang Park is related to the manufacturing of plasma display panels. This invention focuses on flat-panel display devices, specifically liquid crystal displays (LCD) and plasma display panels (PDP). The method involves using a laser transcription technique to form spacers or barrier walls that maintain a predetermined gap between the upper and lower substrates. By ensuring uniform height and width of these components, the display characteristics are enhanced through a simplified manufacturing process.
