A method and apparatus for generating an elemental image by an integral image technique are provided. The method includes normalizing coordinates of dots in a frustum formed in perspective projection by mapping the dots in the frustum into a cube; reversing a grade of depth of the cube viewed from a particular viewpoint; and generating a two-dimensional (2D) elemental image necessary for three-dimensional (3D) display from dots in the cube whose grade of depth is reversed.

Provided are a method of preparing a nanowire grid polarizer, and a nanowire grid polarizer prepared using the same. The method includes: mixing a surfactant and a silica precursor to prepare a mesoporous film composition; coating the mesoporous film composition on a substrate; aging the coated product to form a silica template composite; removing the surfactant inside the silica template composite to prepare a mesoporous material having channels; and filling the channels of the mesoporous material with metal. The method is suitable for the formation of a nanowire having a stable structure, mass production, and large-area production.

Provided is a method of nano-patterning block copolymers and a method of manufacturing a polarizer using the same. The method of nano-patterning block copolymers includes coating block copolymers on a lower substrate to a predetermined thickness, forming a thickness gradient by patterning the block copolymers to have a predetermined aspect ratio, and aligning self-assembled block copolymers in a direction of the thickness gradient by heat-treating the block copolymers having the thickness gradient.

A front light unit and a flat panel display apparatus including the front light unit are provided. The front light unit includes a light source unit and a light guide plate (LGP) which has a plate shape and which guides light emitted by the light source unit. The LGP has a rear surface through which the guided light exits and a front surface opposing the rear surface. The front light unit also includes a front polarizing plate disposed opposite the front surface of the LGP. The front polarizing plate has a polarizer which transmits only light polarized in one direction. The flat panel display apparatus including the front light unit can provide an improved contrast ratio on a front side thereof.

An optical pickup includes at least two vertical cavity surface emitting lasers (VCSEL) disposed adjacent to each other on the same substrate for emitting light having different emission angles, a light path converter for converting the travel path of incident light, an objective lens for focusing incident light to form an optical spot on an optical recording medium, and an optical detector for receiving light which is reflected by the optical recording medium and passed through the objective lens and the light path converter. The optical pickup selectively drives one of the VCSELs so that disks of different thicknesses can be compatibly adopted, and high efficiency of light can be secured.

Provided is an optical guide bar including: a light exit portion; light incident portions, on which light is incident, formed on both sides of the light exit portion; and a reflective portion facing the light exit portion and including a prism pattern that reflects light transmitted through the light incident portions towards the light exit portion. A shape of the reflective portion is determined in consideration of an effective light emission width of the light incident portion so that the intensity of light at any portion of the reflective portion is uniform.

A liquid crystal display with an improved viewing angle and brightness is provided. The liquid crystal display includes a light source unit and a polarized light guide plate having an incident surface onto which unpolarized light from the light source unit is incident. The polarized light guide plate polarizes, collimates, and out-couples the incident light. The liquid crystal display also includes a liquid crystal panel which modulates the light out-coupled and illuminated from the polarized light guide plate to form images, and a diffusion layer which diffuses the light modulated in the liquid crystal panel.

An edge-light type backlight system including a point light source, a light guide panel including a light incident part into which light enters from the point light source and a light emitting surface from which light is emitted, and an optical path-changing unit which changes a propagation path of light traveling inside the light guide panel. The light incident part includes a light incident surface on which a prism pattern is formed, the light incident surface facing the point light source, and first and second surfaces extending from the light incident surface in a direction in which light travels inside the light guide panel and adapted to reflect light passing through the light incident surface to reduce a direction angle, the first and second surfaces being opposite to each other with respect to an optical axis.

An illuminator for a flat panel display device is provided. The illuminator includes a light source generating light; a light guide plate that guides and distributes the light generated by the light source and is made of optically isotropic material; a collimator that is disposed between an end of the light guide plate and the light source and guides the light from the light source onto the light guide plate with a predetermined incident angle; a polarization separation layer that is made of optically anisotropic material having two refractive indices and formed on the light guide plate to transmit first polarized light from the light guide plate and reflect second polarized light from the light guide plate; and a beam out-coupling layer that is formed on the polarization separation layer and out-couples the light incident from the polarization separation layer.
