The Folding Pen

The Folding Pen
​

Well, not exactly a folding pen, but talk from the Samsung (005930.KS) supply chain seems to indicate that Samsung display has solved the problems associated with adding a pen feature to the next iteration of its foldable Galaxy series due out later this year.  The challenges associated with a foldable pen input device are considerable, as the embedded pen sensing component has to be able to flex in the same way as the screen without creases that could cause false input, while at the same time avoiding scratches and deformation from the pen itself.  The use of UTG (Ultra-thin glass) is likely the most logical solution that provides protection while maintaining encapsulation while the foldability is a more difficult fix.
That said, while the production of such a display will be difficult and Samsung will not confirm or deny the addition of the pen to the next foldable, it seems they have confirmed production of the components (display) for May and full device assembly beginning in July, which would infer a September or October release for the Fold 3, which is consistent with the Galaxy Fold (2019) and the Galaxy Fold 2 (2020), both of which were released during September.  The Galaxy Z Flip, Samsung’s other foldable device was released in February.  If such is true, it will increase the chance that the Galaxy Note series will see its end in the near future, as the pen was one of its differentiating features over the standard Galaxy smartphone series.
