A German consortium has launched the KODOS project (Konfektionierter Dünnglas-Verbund für optoelektronische Systeme or “Thin Glass Composites for Optoelectronic Systems”), aiming to enable the roll-to-roll production of thin glass into finished flexible products, creating the entire value chain around production.

KODOS project partners want to be able to offer a complete modular system of functional materials, semi-finished products, tools, and technologies for the roll-to-roll production of optoelectronic systems on thin glass.

Funded by the German Federal Ministry of Education and Research, the consortium includes EMDE development of light, Volkswagen and Deutsche Werkstätten Hellerau, tesa, Von Ardenne, Flabeg, 4JET microtech, Suragus, and the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP.

Automobile manufacturer Volkswagen will evaluate and qualify the use of thin glasses as functional decorative surfaces in cars. For this purpose, the laminated optical basic devices produced in the project are to be tested for their resilience and crash safety. They illustrate the properties of functional surfaces such as lighting, decorative symbols and touch functions.

The Deutsche Werkstätten Hellerau will seal wooden surfaces with the ultra-thin glass as high-tech material and integrate additional functions such as organic light emitting diodes (OLEDs) or sensor surfaces into furniture.

"The aim of the project is to explore and develop economically relevant applications for thin glass. For example, OLED technology can be used as a display and control element in combination with touch functionality based on thin glass in architecture, furniture, household appliances and retail applications. The desired innovation is the combination of coating, structuring, contacting and lamination, as well as the development of a production-ready transition from the processed roll to the ready-to-install semi-finished product", explains Thomas Emde of EMDE development of light and consortium leader. The EMDE development of light will create in the project the requirements definitions for a process optimization in the areas of roll-to-roll and OLED production.
