Definitions

  • the present invention relates to a flat neon sign device, and more particularly, to a flat neon sign device capable of displaying a desired picture as a surface unit.
  • a neon sign is a light emitting device for displaying letters or pictures used for the purpose of an advertisement (hereinafter, the term "advertisement pattern" is used to include all of the designs such as letters or logos for an advertisement).
  • a conventional neon sign that can be easily seen in the surroundings is a line neon sign in which light is emitted from only edge portions of the neon sign to display the advertisement pattern.
  • the advertisement pattern such as a letter or symbol to be advertised is a "circle”
  • light is emitted from only a circumference of the "circle” rather than an entire area of the "circle” in order to display the "circle.” Therefore, it is very difficult to precisely display the advertisement pattern desired by a user through the line neon sign, and there is also a limitation on the advertisement pattern to be expressed.
  • manufacture of the line neon sign for displaying the advertisement pattern requires human's manual works, it is difficult to mass-produce it. Thus, there is a problem in that the production costs may be increased.

  • the '574 patent provides a luminous sign board having a planar board shape, it has a defect that its structure is somewhat complex. That is, in order to provide the luminous sign board, the '574 patent employs three sheets of plate materials: a front transparent legend plate, a center feed through plate and a back crossover cavity plate. Such three plates are mutually combined to selectively form a cavity representing a letter or shape to be expressed.
  • the luminous sign board is finally provided by discharging electricity inside the cavity.
  • the technology disclosed in the '574 patent also poses problems in that it has a complex structure as a whole, and in that because the neon sign uses a background light source of indirect illumination, the fluorescent color of neon is deteriorated. That is, since the conventional neon sign employs the method of displaying only edge portions of the advertisement pattern to be expressed by using the line neon sign, there is a disadvantage in that the advertisement pattern to be expressed is limited and its production costs are increased.
