CEA-Leti, a research and technology organization based in Grenoble, France, discusses its long history and current focus in display technologies. With over 40 years of experience, the institute was a pioneer in LCDs and has been developing OLED technology for two decades. The current primary focus is on micro-LED (µLED) technology, which is seen as promising for its high brightness, wide color gamut, and low power consumption.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

One key area of development is the creation of multifunctional displays. By leveraging the small size of micro-LEDs, space is created within each pixel to integrate additional components. This allows for the inclusion of sensors directly into the display panel, such as cameras or fingerprint readers, enabling new functionalities like gesture recognition. This approach transforms a standard display into an interactive, multifunctional surface.
Beyond consumer displays, CEA-Leti is exploring the use of micro-LEDs for new applications, particularly in high-speed optical communications. The ability to create a matrix of micro-LEDs that can be modulated at very high speeds allows for parallel signal transmission. This is beneficial for data centers, where high-speed, low-power optical interconnects are critical.
CEA-Leti’s role is to develop the core technology and initial prototypes. The organization then partners with companies and facilitates technology transfer for mass production and commercial product development. A notable example is Aledia, a startup created by CEA-Leti that is now developing products for AR and optical communications based on this micro-LED technology.
As a research institute with approximately 2,000 people in Grenoble, CEA-Leti’s strategy involves identifying new technology trends and aligning them with its internal R&D capabilities. The organization receives partial funding from the French government to create initial prototypes, then secures further funding through industrial partnerships and European projects to advance the technology towards commercial viability.
