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.

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.

Abstract: Disclosed herein is a plasma display panel in which afterimage is improved. The plasma display panel according to the present invention includes a panel unit having an upper plate and a lower plate, a frame that supports circuitry, and a conductive material formed between the panel unit and the frame. As such, a conductive material is formed on a bottom surface of a lower plate of a panel. Thus, charges introduced into the lower plate are properly controlled to improve the waveform stability of the panel. Also, a charge characteristic is improved to implement a stable operation. Accordingly, an afterimage time can be reduced. Further, a sheet of a low hardness and light weight is used. It is thus possible to absorb shock and noise of a PDP, accomplish light weight of the PDP and reduce the materials of the sheet.
