A tech breakthrough in Wroclaw! Quantum dots could change the world of displays and LEDs

QNA Technology S.A., a company operating in the Wroclaw Technology Park, has been granted a European patent for an innovative UV-curable ink containing red quantum dots. The European Patent Office has granted protection for both the method of applying the ink and its use in light-emitting devices such as next-generation displays and LEDs. The new patent has just come into force.

Innovative UV inks from Wroclaw. What is it? How does it work?

  • Quantum dots are an innovative semiconductor that can be used to make blue light-emitting diodes, used, for example, in displays, projectors, and LED lighting.
  • Thanks to the high energy of blue photons, it is also useful in applications where light is used to simulate biochemical processes.
  • Thanks to the technology of QNA Technology S.A., all these devices can be printed and will also be characterized by unique parameters and a high level of innovation.

Unique patent already in force

The Wrocław-based company has just been granted a patent for these solutions, which came into force on July 30, 2025. It has also been published in the European Patent Bulletin. The protection covers selected signatory countries of the European Patent Convention in which the company will register accordingly.

Currently, the Convention brings together 39 countries, including all European Union member states, as well as Norway, Switzerland, and Turkey.

Another step in the development of electronics

The patented solution is a technology of significant importance for the electronics sector, with particular emphasis on the new generation of displays.

This is an important step in the process of protecting our know-how. It concerns special UV-curable inks containing quantum dots, which can be used, among other things, in the production of microLED displays, as well as in other areas such as optical communication and photonics.

Artur Podhorodecki, CEO and co-founder of QNA Technology S.A.

According to Artur Podhorodecki, the use of quantum dot technology in microLED displays can significantly reduce the production costs of these devices, which is currently a major barrier to their mass commercialization.

 

Red, blue, and green dots

QNA Technology is not only developing red quantum dot ink technology, but is also working on solutions based on blue and green dots, which will enable the creation of full-color RGB pixels in display devices.

To date, the company has obtained two patents in Poland and filed six further applications with the European Patent Office. In addition, it protects its know-how with 17 Codified Trade Secrets covering key aspects of the technology under development.

QNA Technology S.A. operates in the advanced technology sector, focusing on the development and commercialization of quantum dot-based solutions. Its technologies are used in consumer electronics, display technologies, LED lighting, and biotechnology.
