Aledia, 3D microLEDs for next-generation displays

Published on 28 February 2024
​Smartphone displays that are 5x brighter and 2x more energy efficient than conventional displays at the same price.

Aledia’s brighter and more energy-efficient 3D microLEDs are ushering in a new era in backlighting for displays of all kinds, from virtual reality headsets to video walls.

Aledia, founded in 2011, offers 3D lighting devices for displays of all sizes. With brightness up to 2,000 times higher than OLEDs and LCDs, better image quality, increased contrast, and low production costs, the company’s products are unique on the global market. The 3D microLEDs are protected by 250 patent families, making Aledia the number-one French startup for the number of patents filed.
The brightness and energy efficiency of Aledia’s 3D microLEDs will eventually reduce the battery requirements of a smartphone or laptop by half. Not only will this facilitate outdoor use, but it will also reduce dependence on strategic metals like lithium, cobalt, and manganese. Aledia also targets many other markets, from microdisplays for virtual reality headsets to huge video walls.

The company, which was housed by the CEA until 2019, today employs 230 people at its own 4,000 m2 R&D center. It is also building a production plant that will total 52,000 m2. Collaboration with the CEA continues through a joint laboratory that develops advanced technologies.
