FlexEnable achieves organic curved display win

FlexEnable Technology Ltd. (Cambridge, England), a developer of flexible organic electronics for active optics and displays, has technology shipping in a mass-produced consumer product.

The device, called Ledger Stax, is a cryptocurrency wallet developed by French company Ledger. FlexEnable partnered with display manufacturing companies DKE (Shanghai) and Giantplus (Taiwan) to realise an e-paper display uniquely wrapped around a 180-degree bend.

The Stax features a display radius of curvature not previously achieved in an e-paper product, FlexEnable claims. This is due to the organic thin-film transistors (OTFTs), comprising organic materials and process IP developed, supplied and licensed by FlexEnable.

FlexEnable’s OTFT technology is the first and only organic transistor in mass production, the company claims.

The manufacture of these flexible OTFT backplanes by Giantplus may lead to further flexible displays and optical modules with curved form factors, These could include AR/VR optics, ePrivacy screens, automotive smart windows and organic LCDs.

“The launch of Ledger Stax represents a significant milestone, not just for our company, but for the entire display industry, and the billion-dollar e-paper display market is just the beginning,” said  Chuck Milligan, CEO of FlexEnable, in a statement. “As we ramp up production of FlexiOM materials to meet growing demand for Ledger Stax, the established supply chain is now primed to support a range of future applications in AR/VR optics and beyond, to meet the volume needs of our brand partners.”

Plastic Logic

The origins of FlexEnable go back to Plastic Logic Ltd. Plastic Logic was founded in 2000 as a spin-off from Cambridge University, to develop OTFT backplanes for displays. The company mostly focuses on e-paper displays, but was also involved with OLED displays. The company was split between a manufacturing operation in Dresden, Plastic Logic Germany, and Plastic Logic Ltd. development and IP holder in Cambridge.

 In 2015 FlexEnable was formed out of Plastic Logic Ltd. but went into receivership in 2022 (see FlexEnable emerges from restructuring under US control).

Since emerging from receivership FlexEnable’s operation has expanded to include not only the licensing of organic materials and manufacturing processes but also the manufacture of liquid crystal (LC) optoelectronic modules. These modules are flexible, ultra-thin, ultra-light, and unbreakable.
