Title: Innovations by Yong Won Choi

Introduction

Yong Won Choi is a notable inventor based in Kyungki-do, South Korea. He has made significant contributions to the field of optical technology, particularly in the development of backlight units and light sources. With a total of two patents to his name, Choi's work has implications for various applications in display technology.

Latest Patents

Choi's latest patents include a backlight unit and a light source designed for use in the same. The first patent describes a backlight unit that features a substrate, multiple light-emitting diodes (LEDs) arranged at the corners of a polygon or side by side, and lenses that direct the emitted light in a predetermined direction. This innovative design allows for the creation of white light through the cooperation of at least three LEDs. The lenses possess an asymmetrical irradiation characteristic, enabling uniform mixing of the lights and directing them in an elliptical shape toward the top portion of the backlight unit.

The second patent focuses on a backlight unit with an oxide compound-laminated optical layer. This unit includes a substrate, spaced-apart light sources, and a total reflection layer that reflects the emitted lights upward. The optical layer above the light sources is designed to allow some light to pass through while reflecting the rest downward, inducing optical resonance. This resonance enhances color purity by reducing the half amplitude of a color-based spectrum histogram in the light-emitting spectrum.
