Title:
エレクトロルミネセント単向視認パネル
Document Type and Number:
Japanese Patent JP2009502016
Kind Code:
A
Abstract:
An electroluminescent (EL) one-way vision, see-through graphics panel comprises a sheet of light permeable material with a uniform electrically conductive coating. A print pattern comprising an electroluminescent ink system partially covers the sheet of light permeable material forms an ‘EL lamp’. A design is superimposed on, or forms part of, the print pattern such that the design is visible from only one side of the panel. The design can be a uniform color, but is typically a multi-color graphic image. The EL lamp illuminates the design when subjected to an electrical current. If the light permeable material is transparent, through vision is possible from the other side of the panel through the unprinted portions of the transparent material. A dark colored opaque mask layer faces in the direction of the other side of the panel to mask the other print pattern layers and enable good through vision.
