Story summary

University of Turku researchers have developed a colour-tunable white OLED that eliminates indium tin oxide and heavy metals.
It uses a single-component thin film and a microcavity to produce tunable white light from 3,790 K to 5,050 K.
The design reduces costs and ecological impact by enabling compatibility with existing production lines for flexible surfaces and smart-building panels.
The team plans to advance brightness, efficiency, and stability toward commercialization.
