Korean display manufacturer Samsung SDI and German security printer Bundesdruckerei have demonstrated a passport that features a slim and bendable Organic Light Emitting Diode colour display within a polycarbonate data page. The display can be used to provide a raft of information including a video of the document holder.
According to the suppliers, tommorow’s ID documents will work without contact and without internal batteries. The integration of a display makes electronic ID documents even more difficult to forge and opens up the way for new security applications, they claim.
Samsung SDI developed the display to be just 300µm thick. However, even with the integrated colour display, the data page of the ePassport is still only 700µm thick, the companies claim.
The display comprises an active matrix display with organic light emitting diodes (AMOLED). This means that located behind every pixel of the display is an active electronic circuit with low power consumption. AMOLED displays are said to provide excellent colour images and can be produced in much thinner formats that conventional LCDs.
