Pixel-Flo, a University of Sheffield spinout addressing a critical bottleneck in MicroLED display manufacturing, has raised £5.25 million in Seed funding, led by Northern Gritstone with participation from SCVC, the Parkwalk Northern Universities Venture Fund, and HTGF.
Pixel-Flo's proprietary Continuous-Flow Mass Transfer technology addresses the scalability challenges that have limited mass-market adoption of MicroLED displays, which offer 2-5x higher brightness and 2-4x greater efficiency than traditional displays. Existing mechanical mass transfer techniques scale poorly, but Pixel-Flo's fluidic self-assembly approach delivers high continuous throughput at radically reduced processing and material cost, extending the industry-standard coating approach so that MicroLED-enabled products from smartwatches to TVs can reach mass market price points.
The oversubscribed round will support Pixel-Flo's transition from laboratory development to industrial scale-up, funding team expansion and a move to new lab and office space. The business recently hired Taiwan-based Sanger Hsu as Business Development VP to focus on early customer engagement in a critical display-technology market.
Pixel-Flo was founded by Dr Rick Smith, Dr Suneal Ghataora and Simon Jones, building on semiconductor photonic research from Dr Smith's lab and long-running LED research at the University of Sheffield's School of Electrical and Electronic Engineering, alongside Simon Jones's display-industry commercial experience. The company was part of Northern Gritstone's NG Studios deeptech venture builder cohort last year.
This investment allows us to expand our team and demonstrate our unique technology on a commercial coating system, enabling partnership and evaluation by display manufacturing partners. We are proud to have a fantastic international consortium of complementary investors led by Northern Gritstone supporting our international ambitions to enable huge new market opportunities for microLED.
Pixel-Flo is a great example of the deep-tech innovation with global ambitions emerging from the Northern Arc that Northern Gritstone strives to support. As a graduate of our NG Studios venture building program, the company combines world-class science with a clear path to commercial impact. By developing a scalable, lower-cost solution, Pixel-Flo's MicroLED mass transfer assembly process has the potential to unlock MicroLED displays for the mass market.
Deep Tech is full of breakthrough technologies looking for a problem to solve. Pixel-Flo inverted that – an elegant solution to the bottleneck that has held microLED back, a display technology that outperforms on every metric. The syndicate around them reflects what the management team has already built.
From my experience in displays and printed electronics, I know all too well how challenging it is to scale new display technologies. Pixel Flo's approach targets precisely this critical bottleneck in the micro-LED market – and this team has what it takes to deliver a key technology for the next generation of displays.
