Abstract: A diffusion sheet diffuses light to enhance luminance uniformity. The diffusion sheet includes a base film and a diffusion layer. The base film is optically transparent. The diffusion layer is formed on a surface of the base film. The diffusion layer includes a diffusion pattern having a plurality of first diffusion members that enhance front-view luminance. A cross-section of each of the first diffusion members having an arch shape, the cross-section being taken along a line that is substantially perpendicular to a longitudinal direction of the first diffusion members. The backlight assembly requires no prism sheet, which is usually used for enhancing front-view luminance, thus lowering the manufacturing cost.

Abstract: A backlight assembly includes a bottom chassis, a planar fluorescent lamp, a mold and an inverter. The bottom chassis includes a bottom portion and a side portion. The planar fluorescent lamp generates planar-light. The bottom chassis receives the planar fluorescent lamp. The mold fixes the planar fluorescent lamp such that a gap is generated between a portion of the mold and the planar fluorescent lamp to absorb impact between the mold and the planar fluorescent lamp. The inverter generates discharge voltages to drive the planar fluorescent lamp.

Abstract: A compact, light, and uniformly bright backlight assembly and a display device are disclosed. The backlight assembly includes a light source assembly, a substrate, and a transflective member. The light source assembly emits a first light with a first luminance uniformity. Then, the first light passes through the substrate above the light source assembly for producing enhanced luminance uniformity. Again, after the light is reflected from and/or transmitted through the transflective member, the luminance uniformity is even more enhanced. Therefore, the volume, weight, and luminance uniformity of the backlight assembly and the display device are enhanced.
