Lumiode

Lumiode is a US-based company specializing in the development of microLED microdisplay technology. The company has created a unique, truly monolithic process for fabricating TFT backplanes directly on top of microLED arrays, eliminating the need for wafer bonding. This innovative approach enables the production of highly bright and efficient microdisplays. Lumiode's technology involves depositing amorphous silicon on LED epiwafers and then laser crystallizing it to low-temperature polysilicon (LTPS) without damaging the LED devices.

As of 2019, Lumiode had demonstrated a 0.13-inch monochrome green microdisplay prototype with 16,000 pixels and a pixel density of 1,400 PPI. This display was capable of achieving an impressive brightness of up to 1,000,000 nits, with the potential to reach over 10 million nits. The company's technology allows the LEDs to maintain their high performance throughout the manufacturing process. Lumiode operates as a fabless company, planning to outsource all production steps while focusing on its core TFT deposition process technology. The company utilizes an in-house production tool that works with third-party epiwafers.

Looking ahead, Lumiode aims to develop full-color displays using blue LED devices with a color conversion layer. The company has also expressed plans to begin offering commercial high-brightness monochrome displays in the near future, targeting applications that require extreme brightness and efficiency in a compact form factor.
