  • Publication number: 20240074258
    Abstract: An electronic device includes a display device, which may be fabricated using a described method. The display device includes a glass substrate including a first surface, a second surface opposite the first surface, and a side surface between the first surface and the second surface, an outermost structure on the first surface of the glass substrate and located adjacent to an edge of one side of the glass substrate, and a display area including a plurality of light emitting areas on the first surface of the glass substrate and located farther from the edge of the one side of the glass substrate than the outermost structure is. A minimum distance from the side surface of the glass substrate to the outermost structure is equal to 130 ?m or less.

  • Publication number: 20080106198
    Abstract: A display apparatus includes a plasma display panel (PDP) and a filter having a panel side facing a display surface of the PDP and an opposing viewer side facing away from the display surface. The filter includes an external light shield having a first base unit and first pattern units. The first pattern units absorb external light from the viewer side and are substantially parallel to a first axis. The filter includes an electromagnetic interference (EMI) shield overlapping the external light shield. The EMI shield includes a second base unit and second pattern units. The second pattern units are conductive and substantially parallel to a second axis. An interior angle between the first axis and the second axis can be within a range of 40 to 50 degrees.

  • Publication number: 20080100535
    Abstract: A display apparatus includes a plasma display panel (PDP) and a filter. The PDP has a display surface, and the filter has a panel side facing the display surface of the PDP and an opposing viewer side facing away from the display surface. The filter includes a base unit. The filter also includes pattern units that absorb external light from the viewer side. The pattern units have boundaries that define widths of pattern tops and widths of pattern bottoms. A distance between a pattern top and a pattern bottom defines a pattern height. A distance between adjacent boundaries, of a pair of adjacent pattern units, at adjacent pattern bottoms can be less than a distance between the adjacent boundaries at adjacent pattern tops, less than the pattern height, and greater than a width of at least one of the pattern bottoms.

  • Publication number: 20080088535
    Abstract: A display apparatus includes a plasma display panel (PDP) having an upper substrate at which black matrices are disposed. The apparatus includes an external light shield having a panel side facing a display surface of the PDP and an opposing viewer side facing away from the display surface. The light shield includes a base unit and includes pattern units that absorb external light from the viewer side. The pattern units have boundaries defined by intersections of the pattern units and the base unit. The boundaries define widths of pattern tops disposed toward the panel side or the viewer side and define widths of pattern bottoms disposed toward the other of the panel side and the viewer side. A distance between a pair of adjacent black matrices is 4 to 12 times greater than a distance between adjacent boundaries, of a pair of adjacent pattern units, at adjacent pattern bottoms.

  • Publication number: 20060138923
    Abstract: This document relates to a display apparatus, and more particularly, to a plasma display panel and a mono-layer optical filter for a PDP and manufacturing method thereof. A plasma display apparatus according to an embodiment of the present invention comprises a front panel, an EMI shielding film comprising metal meshes formed in a mesh type, for shielding EMI incident from the front panel, and a medium layer formed around the metal meshes, for shielding NIR, and an AR/hard coating film coated on at least one surface of the EMI shielding film, for shielding the reflection of light incident from the outside.
