Abstract
An organic thin film display element comprises an organic thin film containing donor moleculaes and acceptor molecules and a pulse voltage source for causing a charge transfer between the donor molecules and the acceptor molecules. The charge transfer varies the optical characteristic of the organic thin film, whereby the organic thin film displays an image.
Claims19
A thin organic film display element, comprising:
- a thin organic film layer including at least one first thin organic film containing donor molecules and at least one second thin organic film containing acceptor molecules, wherein said thin organic film layer has at least two interfaces between said first thin organic film and said second thin organic film;
- and
- means for causing a charge transfer between the donor molecules and the acceptor molecules, said charge transfer varying the optical characteristics of the thin organic film layer, whereby the organic thin film layer displays an image.
A thin organic film display element, comprising:
- a thin organic film layer which comprises at least one thin organic film containing both donor molecules and acceptor molecules;
- and
- means for causing a charge transfer between the donor molecules and the acceptor molecules, said charge transfer varying the optical characteristic of the thin organic film, whereby the thin organic film displays an image;
- wherein a thin film containing electrically insulating organic molecules is formed on at least one surface of said thin organic film layer.
