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： The backlight for a flat display device including a light source, a light guide plate and a surface hologram is provided. The light guide plate is installed at one side of the light source, and light from the light source travels in the light guide plate while being totally reflected. The surface hologram is formed on at least one surface of the light guide plate. The surface hologram has a pattern of a predetermined grating interval and a predetermined grating depth in order to diffract light at a predetermined angle toward the light guide plate.

摘要： An illumination apparatus and method for a display device designed such that light is incident on a hologram or hologram pattern at an angle for which diffraction efficiency is the highest. The illumination apparatus includes at least one point light source which emits light and a light guide plate (LGP) which has the at least one point light source disposed on a side thereof and a hologram pattern on a top surface which permits the light incident from the point light source to exit from the top surface. The side of the LGP facing the point light source is inclined such that the light is incident obliquely on the hologram pattern at an altitude angle which provides high diffraction efficiency.
