Display card, especially a chip card with an integral display, has a graphical layer that is covered with a semi-transparent layer that allows transmission of light outwards from a display, while blocking incident light

摘要

Display card comprises a card body (5) with an integral display (3) e.g. organic LED. A graphical layer (18) covers the display and is transparent over at least a part of the display. Between the display and the graphical layer is a semi-transparent layer (9) that allows the passage of radiation from the display towards the card surface, while being reflecting or absorbing for light travelling in the opposite direction.
