A Swedish SME has developed a manufacturing method of thin, all-organic, lightweight and flexible light emitting patches powered by low-voltage DC. To be used for medical applications, and in other control panels/light emitting electronics e.g. automotive, smart card and white goods applications, as well on packaging of consumer goods. The SME offers manufacturing partners and distributors to incorporate new features in their products based on light, to establish this innovation into the market.



A Swedish SME has developed a new method to manufacture thin, all-organic, lightweight and flexible light emitting patches, which provides a solution for the large unmet need for printable light. The SME has the core competence how to make the individual patch and will, primarily, deliver ink to print the patches, but can also provide equipment components to facilitate production.

The technology behind the patches is light-emitting electrochemical cells (“LEC”), which has been developed by the company founder at the Organic Photonics and Electronics group at Umeå University in Sweden. The LEC can be printed in ambient conditions entirely from solutions.

The market and potential applications are as follows:
Within the medtech/healthcare sector, printable and disposable light can replace clumsy hospital equipment for light treatment of skin conditions, eye disease, baby jaundice, wound healing etc.
The patches can be combined with printed electronics to create applications with indicators, logos and other user interactions for wearables (and other IoT) and for control panels in automotive and white goods.

Packaging for consumer goods, such as fast-moving consumer goods and luxury brand packaging, can be enhanced by lighting features. Security features can also be added for fraud-protection and consumer information. Usage could also spread to functional light, where the patch can be used in combination with different sensors to indicate expired products, or to guide customers to selected products. The new printable light-solution can provide several colours with low driving voltage, 4-9 VDC. A separate power supply is not required if it is integrated with an RFID power harvesting antenna, which is enough to turn on a 10mm x 20mm light patch.

The SME offers manufacturing partners and distributors to incorporate new features in their products based on light, to establish this innovation into the market. Other agreements of interest are within research and technical assistance/cooperation.

Advantages & innovations

Cooperation plus value: 
* The patches and devices can be produced in ambient conditions, allowing for custom designs in low volumes at a reasonable cost, and the products can be tailored to suit end-customer's needs. * The patches and devices are mobile and safe, since they can be powered by AAA- or watch batteries. * Production equipment is possible at 1/100th cost of OLED manufacturing equipment. * Viable production cost even at small volumes, allowing for customized devices. * The LEC-patches can be produced completely metal free and can be recycled with non-organic plastic waste. * The LEC (Light-emitting electrochemical cells) is superior to the LED in thin and flexible applications since the LEC can emit light from its entire surface in a less than millimetre thick sandwich structure. * The LEC can be produced by depositing three layers, from solutions, with a spray-deposition technique, in ambient conditions. The technology eliminates the need for cleanroom, vacuum and high-temperature deposition. I.e. the possibility to add printable light significantly reduces cost and complexity of production. * Individual patches can be produced at €2, compared to €20 for OLED. With a million devices per application and year, the savings are in the magnitude of million. * The equipment is inexpensive and can be used in conjunction with printed electronics or stand-alone. * The resulting LECs have homogenous light-emission from the entire surface, and can be produced in a variety of colours, from blue to near infrared.

Partner sought

Cooperation area: 
The Swedish company's core competence is how to make the inks for manufacturing the light patches. The company seeks partnerships mainly with companies interested in incorporating new features in their products based on light, on a worldwide market. As a part of the technology offer from the SME, other agreements of interest are within research and technical assistance/cooperation. The company is also looking for equity investors, to be able to scale up manufacturing and marketing capabilities.
