  • Patent number: 8102104
    Abstract: Provided is a front-side filter which can be easily attached to a cover of a display device, but is difficult to detach from the cover even after long term use and further provided is a PDP device including the same filter. The front-side filter includes a filter base having at least one function among a near-infrared ray shielding function, and a neon light shielding function, and an electromagnetic wave shielding function; and an antireflective layer with an edge pattern, formed on a side of the filter base in such a way that the entire edge portion or a part of the edge portion of the filter base is exposed through the edge pattern to provide a fixing means formed in the edge pattern.

  • Publication number: 20090128895
    Abstract: A filter 100 for a display device includes a transparent substrate 110; a near infrared ray blocking layer 120; and electromagnetic shielding layer 130; an external light blocking layer 140; and a color compensation layer 150. The near infrared ray blocking layer 120 is formed on the transparent substrate 110 and includes a metal thin film and a metal oxide thin film which are alternately layered, each of the metal thin film and the metal oxide thin film being layered one or more times. The electromagnetic shielding layer 130 is formed on the near infrared ray blocking layer 120 and includes a metal mesh pattern. The external light blocking layer 140 includes an external light blocking pattern 144, the external light blocking pattern including a plurality of external light blocking parts with a wedge shape which are filled with a light absorbing material and a conductive material.

  • Publication number: 20090058250
    Abstract: A filter for a display apparatus is placed in front of a display panel, wherein CIE chromaticity coordinates of the filter under a standard of a D65 light source have values of ?2.0?a*?2.0 and ?2.0?b*?2.0. The CIE chromaticity coordinates of the filter under the standard of the D65 light source have a value of 60?L*?80. The colorants include a first colorant absorbing 380 nm to 480 nm wavelength light, a second colorant absorbing 450 nm to 550 nm wavelength light, and a third colorant absorbing 560 nm to 620 nm wavelength light. The first to third colorants can be contained in at least one of a color compensating layer, a low-refraction layer having a refractive index of 1.5 or less, an external light shielding layer, a hard coating layer and an adhesive layer.

  • Publication number: 20080259478
    Abstract: Disclosed is an optical filter for a display filter in which an adhesive layer excluding organic acidic substances is used, thereby achieving superior durability. The optical filter includes an anti-reflection film, a transparent substrate, a mesh film, and a color correction film. In this instance, an inorganic acidic adhesive layer is formed on a surface of at least one of the anti-reflection film, the mesh film, and the color correction film.

  • Publication number: 20080219011
    Abstract: Disclosed is an optical member for a display apparatus which includes a plurality of colorants. The optical member includes a neoncut colorant where the full width half maximum (FWHM) of the peak wavelength is about 35 nm or less, wherein a transmittance ratio (B/R) of blue light (B) with a wavelength of about 400 to 500 nm with respect to red light (R) with a wavelength of about 600 to 700 nm is about 0.84 or less.
