Optical Technology Award Winners – OLED Displays and Warm Labels

The International Optical Technologies Association recently announced the winners of its inaugural Excellence in Optical Technologies Awards, during a ceremony at the Optical & Digital Document Security™ conference in Warsaw, Poland.

Whilst awards were presented in seven categories, the winners of Best Disruptive Technology and Best Product Security Application caught the attention of Tax Stamp & Authentication News™.

OLED display + wireless powering

The China Banknote Printing Technology Research Institute (CBPTRI) won Best Disruptive Technology for its anticounterfeiting solution that combines flexible OLED (organic light-emitting diode) display technology with the wireless communication capabilities of smartphones.

The solution can be integrated into banknotes, passports, or product packaging to create a visible light- emitting security feature. Powered by a smartphone’s wireless reverse-charging module, the OLED display lights up when the phone’s transmitter antenna aligns with the component’s receiving antenna.

What distinguishes this innovation is its unique structural design. The anode and bridging layers of the component are fabricated in a single process using the same material, which allows the antenna to be integrated directly within the OLED structure, reducing resistance and enhancing power transfer efficiency.
