Title: Jun Sang Park: Innovations in Light Guide Plate Technology

Introduction:

In the world of innovations and patents, certain individuals stand out for their exceptional contributions. One such innovator is Jun Sang Park, a resident of Gumi-si, South Korea. With an impressive portfolio of two patents, Mr. Park has made significant advancements in the field of light guide plate technology. Let's explore his innovations and their potential impact.

Patent 1: Light guide plate for surface light source device and backlight unit using the same

One of Jun Sang Park's notable patents is for a light guide plate designed for surface light source devices. This invention incorporates an incident surface that allows light from lamps positioned along a predetermined axis to be incident upon it. The emitted light is then distributed via an emitting surface. The back surface of the light guide plate contains microprism patterns that ensure high front brightness, excellent brightness uniformity, and eliminate the moiré phenomenon.

Furthermore, the unique arrangement axis of the lamps and microprism patterns allows for optimal light distribution and reduces the need for additional optical sheets in a backlight unit. This patent has great potential in enhancing the efficiency and quality of surface light source devices.

Patent 2: Optical sheet for TFT-LCD backlight unit and liquid crystal display having the optical sheet

Jun Sang Park's second patent focuses on the development of an optical sheet for TFT-LCD backlight units. This invention features a transparent base sheet with a diffusion pattern comprised of a plurality of protrusions. These protrusions, forming a light diffusion layer, are designed in a way that ensures that the aspect ratio, which is the ratio of the unit body portion's radius to the protrusion's thickness, is greater than or equal to 0.8.

By employing this diffusion pattern, the optical sheet is capable of uniformly diffusing light from the backlight unit, contributing to enhanced display quality in TFT-LCD devices. This innovation showcases Park's prowess in creating cutting-edge technologies for the ever-evolving display industry.
