    摘要： An optical plate and a tiled display apparatus having the optical plate of the present invention include a base substrate and a Fresnel lens having a plurality of Fresnel patterns protruding toward the base substrate from a flat upper surface. The optical plate further comprises an anti-reflection layer, and a high-refraction layer having a refractive index higher than that of the anti-reflection layer. The optical plate comprises an adhesive layer disposed between the Fresnel lens and the base substrate to affix the Fresnel lens to the base substrate, and a spacer disposed between the Fresnel lens and the adhesive layer to maintain a distance between the Fresnel lens and the adhesive layer. The base substrate includes a first portion having a first thickness, a second portion having a second thickness thinner than the first thickness and a connecting portion disposed between the first and second portions.

    摘要： A light-guide plate includes a base plate, first protrusion patterns and second protrusion patterns. The first protrusion patterns are formed on a left portion of an upper surface of the base plate with respect to a central line of the upper surface. The first protrusion patterns have a cross-section of a trapezoidal shape which has a top and a bottom parallel with each other and first and second inclined sides inclined at different angles with respect to the bottom side. The second protrusion patterns are formed on a right portion of the upper surface with respect to the central line. A cross-section of the second protrusion patterns have the trapezoidal shape and disposed substantially symmetrical to the first protrusion patterns with respect to the central line.

    摘要： An optical sheet includes a base layer, a light-condensing layer and a plurality of light-reflecting portions. The light-condensing layer includes a plurality of light-condensing portions formed on a second surface of the base layer along a first direction extending from a first side surface to a second side surface perpendicular to the first side surface. The light-condensing portions extended in a second direction crossing the first direction at an angle with respect to the side surface. The light-reflecting portions are formed in the first surface along the second direction and corresponding to a plurality of recesses where the light-condensing portions meet each other. The center of the light-reflecting portion is off set from the recesses along the first direction.

    摘要： A backlight assembly and a display apparatus having the backlight assembly are disclosed. A diffusion plate is provided above a plurality of lamps. Diffusion patterns that cause contrast inversion and diffusion patterns that do not cause contrast inversion are arranged on a surface of a diffusion plate, in an alternating manner along a longitudinal direction of the lamps. Thus, a brightness difference between a first area in which the lamps are positioned and a second area between two adjacent lamps is reduced, thereby improving a brightness uniformity of light from the backlight assembly.
