Description
Summary:We have successfully developed an advanced and highly secure anti‐counterfeiting device based on quantum‐dot light‐emitting diodes (QLEDs). This novel device exhibits several key attributes, including affordability, non‐replicability, ease of detection, and exceptional security. By incorporating both electroluminescence and photoluminescence modes, our device offers versatility in satisfying different levels of anti‐counterfeiting needs. To enhance its security further, we have integrated physically unclonable functions (PUFs) and combined them with a pattern recognition system. This integration ensures the device's uniqueness and enables it to meet the most stringent anti‐counterfeiting requirements. The achieved results demonstrate the significant potential of our device in combating counterfeiting and safeguarding various industries.
