Abstract

A document including an integrated display device that has several triggerable display elements, each of which is designed to emit an optical signal for representing first data stored in the document whereby the display device is designed for cyclical activation of the display elements for rendering the first data in sequential image regeneration periods, and whereby the display device is designed in such a way that the emission of the optical signals of at least a subset of the display element takes place with a chronological delay, whereby it is not possible to visually perceive the chronological delay.
