Latest Patents

One of her latest patents involves a backlight unit that includes a light guide panel (LGP) and a point light source emitting light at the edge of the LGP. This invention features a refraction member positioned between the point light source and the LGP, which refracts the emitted light toward the optical axis of the point light source. This design reduces the azimuth angle of the light incident upon the LGP. The refraction member consists of a prism array with a V-shaped prism pattern, ensuring that the apex of the prism pattern faces the edge of the LGP. Additionally, a transparent portion prevents total reflection of light by the prism pattern along the optical axis of the light source.

Another notable patent by Su-mi Lee describes a backlight unit that includes a point light source and a light guide panel with a holographic pattern. This pattern is designed in a concentric circle shape centered at the point light source. By maintaining a constant incident azimuth angle of light on the holographic pattern, the efficiency of light emitted through the exhaust surface is improved. Furthermore, this design allows for a uniform distribution of the exhaust azimuth angle, resulting in consistent brightness from the exhaust surface.
