HP SAILs into flexible display waters

HP's research labs (HP Labs) have been quietly working away for some time on key technical aspects of flexible electronics, including their application to flexible displays.

Now they have announced publicly progress made in their "SAIL" process (Self-Aligned Imprint Lithography), which is a roll-to-roll manufacturing process for electronics, which if married with a flexible display technology like e-Ink film, can produce flexible displays.

They work in collaboration with a number of partners, including the Flexible Display Center (FDC) at Arizona State University

On the HP web site there is a promotional video on SAIL, starring Carl Tausig the HP Lab's Lab Director for the effort and you can read the full Press Release here: HP and Arizona State University Demo Flexible, Unbreakable Displays

One of the key aspects to get across about the SAIL process is that the multiple semiconductor and other layers and all laid down on the flexible substrate at the start, before the layers are etched away. This avoid all problems due to alignment that occur in processes where the layers are laid down, etched, then another layer laid down, then etched etc.
