Latest Patents

One of Hark Lim Choi's latest patents is a light unit for a display device. This innovative light unit serves as a backlight for LCD panels and is designed to allow light entering from the side to exit in a perpendicular direction. The unit comprises a light source that emits white light, a light guide plate positioned adjacent to the light source, and a color dispersion sheet that refracts light at different angles based on wavelength. Additionally, a diffraction pattern is formed on the light guide plate to ensure that light passes through the color dispersion sheet at the same angle.

Another significant patent is related to a projection system. This system features a color corner that includes a dichroic filter with a flat plate structure, which improves color separation characteristics while simplifying the manufacturing process. The projection system is equipped with an illumination unit that separates S-polarized light from non-polarized white light, along with a polarized beam splitter that transmits selected color components while reflecting others. The flat plate dichroic filter defines distinct optical paths for the separated light components, enhancing the overall projection quality.
