Abstract: There is provided a filter of a display device capable of ensure a contrast ratio equal to or more than a predetermined value in various viewing angles. The filter of a display device includes a transparent film; and a plurality of stripe patterns formed parallel to both surfaces of the transparent film, wherein a width (a) of the stripe patterns and a thickness (t) of the transparent film are adjusted to a critical angle (?c) of 20 to 50°.

Abstract: The present invention provides an electromagnetic wave-shielding film which includes a transparent substrate, an electromagnetic wave-shielding layer which includes a conductive pattern formed in at least a portion of the transparent substrate, and an adhesive transparency layer which is formed on the electromagnetic wave-shielding layer to fill a groove of the conductive pattern and contains a near infrared-absorbing dye, and an optical filter and a plasma display panel including the electromagnetic wave-shielding film.

Abstract: Disclosed are a light guide plate for a non-contact type coordinate input system, a system including the same, and a non-contact type coordinate input method using the same. More particularly, the present invention relates to a light guide plate for a non-contact type coordinate input system, which eliminates inconvenience of a conventional contact-type coordinate input system inputting coordinates through direct contact, and which can reduce use of sensors and optical loss as much as possible. The present invention also relates to a system including the same, and a non-contact type coordinate input method using the same.

Abstract: Disclosed herein is a PDP filter having a laminated structure of a transparent conductive film type electromagnetic wave-shielding layer and one or more other functional layers, in which at least two edge portions of the surface of the transparent conductive film type electromagnetic wave-shielding layer, which is in contact with the functional layer, are not exposed outside the laminated structure of the PDP filter.

Abstract: There is provided a PDP filter for absorbing near infrared ray capable of significantly reducing the kind and amount of dyes that are used to block a near infrared ray (NIR) emitted from PDP, the filters having physical properties that are improved when compared to conventional PDP filters for absorbing near infrared ray in which a large amount of 2, 3 or more dyes are used to block wide NIR spectra. The PDP filter includes a dye whose maximum absorption wavelength to a near infrared ray ranges from 880 to 1000 nm, and preferably from 900 to 960 nm. The PDP filter can be useful to improve its productivity, reduce the manufacturing cost and prevent the decrease in the light transmittance by unnecessary dyes.

Abstract: The present invention relates to a film for color compensation and a multi-functional film for color compensation and near IR absorption for a PDP filter comprising a cyanine dye represented by the formula 1 below and a plasma display panel filter comprising the same: where definition of R1 to R4 and A are given in the specification. The film for color compensation and the multi-functional film for color compensation and near IR absorption of the present invention selectively absorbs light in the 560-600 nm region, can improve film durability and can improve contrast and color saturation of PDP images.

Abstract: A method for fabricating a carbon nanotube (CNT) nanoarray, which includes the steps of forming a thin film of supramolecules on a substrate on which metal catalyst for CNT synthesis is deposited, inducing the self-assembly of the supramolecules by annealing to form a regular structure, selectively staining the formed regular structure with a metal compound, etching the metal compound-stained thin film to form a nanometer or smaller size pattern, forming a nanopattern of metal catalyst by using the nanopattern of supramolecules stained with the formed metal compounds, and growing carbon nanotubes (CNTs) vertically on the formed metal catalyst nanopattern. A biochip is readily fabricated by binding bioreceptor(s) to CNTs of the CNT nanoarray.

Abstract: A method for forming a nanopattern of supramolecules, which includes the steps of: forming a thin film of supramolecules on a substrate; self-assembling the supramolecules by annealing to form regular structures; selectively staining the formed regular structures with a metal; and etching the metal-selectively stained thin film to remove a portion of the thin film, which was not stained with the metal. Such method enables the fabrication of nanoarray devices in which bioreceptors are attached to the formed nanopattern of supramolecules on the substrate.
