Abstract: An optical sheet for three-dimensional images and a three-dimensional image display device using the same, are discussed. According to an embodiment, the three-dimensional image display device includes a display unit to display two-dimensional images using unit pixels each including at least three colors of sub-pixels, and an optical sheet to convert the two-dimensional images into a plurality of different three-dimensional images, and the neighboring three-dimensional images are overlapped with each other by a predetermined range. With the above described configuration, the curved lenses are tilted to provide neighboring viewers with three-dimensional images overlapped with each other by 15% to 60%. As a result, a ratio of the horizontal and vertical display resolutions of the three-dimensional images can be equal to a ratio of the horizontal and vertical display resolutions of the two-dimensional images, and the quality of three-dimensional images can be improved.

Abstract: A liquid crystal display (LCD) comprises: a first substrate and a second substrate; a liquid crystal layer between the first and the second substrates; and a fluorescent color filter responding to light over the first substrate, thereby the fluorescent color filter supplies the light to the liquid crystal layer. A method for fabricating a LCD includes: preparing first and second substrates; depositing fluorescent material over the first substrate to form a color filter, the fluorescent material emitting the visible light in responding to the ULTRAVIOLET rays; and forming a liquid crystal layer between the first and second substrates.

Abstract: A three-dimensional display device includes a plurality of projection portions to project a plurality of images, respectively, a plurality of wedge-shaped light guide plates corresponding to the plurality of projection portions, respectively, to emit the plurality of images, respectively, and a plurality of directional diffuser screen corresponding to the plurality of wedge-shaped light guide plates, respectively, to diffuse or transmit the plurality of images.

Abstract: An image display device includes a display panel, a first substrate over the display panel, a plurality of first electrodes on the first substrate, a plurality of second electrodes alternately arranged with the plurality of first electrodes, a second substrate facing the first substrate, a replica layer on the second substrate and having a concave pattern of half-cylinder shape, the concave pattern facing the second electrode, and a liquid crystal layer in the concave pattern.

Abstract: Provided is a channel resource assignment method for fair channel resource reservation in a mesh WPAN, in which the amount of channel resources is fairly reserved when devices share the channel resources. The channel resource assignment method in a mesh Wireless Personal Area Network (WPAN) includes the steps of: (a) transmitting beacons of all devices and adding an amount of channel resource to be reserved to the beacons so as to assign the channel resource for fair channel resource reservation between corresponding devices and adjacent devices when a mesh network is configured; (b) accumulating the amount of the channel resources reserved by all the adjacent devices except the corresponding device; and (c) determining the amount of the channel resources to be reserved.
