DOCUMENT COMPRISING AN INTEGRATED DISPLAY DEVICE

摘要

The invention relates to a document comprising an integrated display device (102) that has several triggerable display elements (103), each of which is designed to emit an optical signal for representing first data (106) stored in the first in the document. The display device is designed to cyclically trigger the display elements in order to represent the first data in successive image repetition periods. Furthermore, the display device is designed such that the optical signals of at least one subset of the display elements are emitted with a delay that is not visible.
