摘要： A light guide plate having a multi-periodic micro pattern, which can minimize chromatic dispersion, and an illumination apparatus for a display device employing the light guide plate are provided. The light guide plate includes a top surface and a micro pattern formed on the top surface and allowing light, which is incident from a first side surface of the light guide plate, to be emitted from the top surface. The micro pattern is a combination of at least two periodic patterns having different periods to reduce chromatic dispersion of light emitted from the top surface.

摘要： A backlight unit for a flat panel display and a flat panel display apparatus having the same. The backlight unit for a flat panel display displaying a predetermined image includes: a light source which emits light; a light guide panel having an incident surface facing the light source and which totally reflects light incident through the incident surface toward the flat panel display; and a holographic pattern that includes a plurality of diffraction gratings that are continuously repeated on at least one of an exit surface of the light guide panel and the opposing surface and diffracts light incident into the light guide panel. A depth of the diffraction grating progressively increases away from the incident surface along a length direction of the light guide panel. The backlight unit for a flat panel display and the flat panel display apparatus having the same have a simple structure that can acquire surface light using a holographic pattern while achieving uniform brightness distribution across the entire light-emitting surface.

摘要： A backlight unit includes a point light source emitting light and a light guide panel including a holographic pattern formed to have a concentric circle shape having a center at the point light center. Thus, since the incident azimuth angle of light incident on the holographic pattern can be made constant, an efficiency of light exhausted through the light exhaust surface can be improved. Also, since the distribution of the exhaust azimuth angle of the exhaust light can be made uniform, a uniform brightness can be obtained from the exhaust surface.

摘要： A backlight unit is provided including a light guide panel (LGP), a point light source emitting light at an edge of the LGP; and a refraction member being positioned between the point light source and the LGP and refracting the light emitted from the point light source toward the optical axis of the point light source in order to reduce the azimuth angle of the light that is incident upon the LGP. The refraction member includes a prism array in which a V-shaped prism pattern is repeatedly arrayed, the apex of the prism pattern facing the edge of the LGP, and a transparent portion that prevents the light from being totally reflected by the prism pattern in a region along an optical axis of the light source.
