Title: Hee Dong Kim: Innovator in Display Technology

Introduction

Hee Dong Kim is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of display technology, particularly in the development of light guide plates and liquid crystal display devices. With a total of 2 patents, his work has had a notable impact on the industry.

Latest Patents

Kim's latest patents include a light guide plate and a liquid crystal display device having the same. This innovative light guide plate is strategically positioned upstream of a liquid crystal panel to refract light supplied through its edge toward the panel. The design features a plate body located adjacent to a light source, which activates when a supply voltage is applied. Additionally, a series of pyramidal diffusing elements are arranged in a specific pattern on the plate body’s surface. Each diffusing element is uniquely rotated about an axis extending through its vertex, allowing for precise angling between 10° to 35° relative to a reference line connecting the light source's central point to that of the plate body.

Another significant invention by Kim is the total internal reflection micro lens array, designed for wide-angle lighting systems. This micro lens array consists of multiple Fresnel lens structures on a single optical incidence surface. Each structure contains grooves with reflecting and refractive surfaces, enabling incoming radiation to be internally reflected and refracted, ultimately exiting the lens structure.
