Abstract: A picture display device is disclosed comprising a suitable substrate carrying a plurality of color cells wherein each color cell is capable of exhibiting a change in its external color from a first color to a second color and/or of emitting electromagnetic energy at least in the form of visible light. Each said color cell comprises color change and/or luminescent means characterized in enabling said cell to exhibit a color change from said first color to said second color and/or in enabling said cell to emit electromagnetic energy at least in the form of visible light in correlation to the application of electrical current and/or voltage to the said cell; suitable electrical connections electrically connectable to a suitable electrical power supply and adapted to provide said color cell with a suitable electrical current and/or voltage; said device characterized in being substantially disposable.

Abstract: A disposable picture display device having a suitable substrate which carries a plurality of color cells. Each color cell is configured such as to exhibit a change in its external color and/or to emit electromagnetic energy at least in the form of visible light in correlation with the application of electrical current and/or voltage to the cell. Suitable electrical connections to each color cell are provided. The electrical connections being electrically connectable to a suitable electrical power supply and adapted to provide the color cell with a suitable current and/or voltage.
