IDTechEx’ insight on touch technologies for flexible displays: Page 3 of 3

The technologies seeking to unseat ITO (Indium Tin Oxide) are by now themselves old, at least in the sense that they have been around for a decade and a half, but they now have to compete on flexibility and foldability too if they are to be successful in flexible displays.

In its assessment, IDTechEx Research anticipates that all display makers will build some know-how for both just in case, but that no single approach will totally prevail in production soon.

Those with sufficient technology know-how and IP protection will pursue the on-cell approach for the current display sizes. They will also continue to make progress on translating this technology to ever larger areas, often chasing a high-priced high-performance premium display positioning.  Others will pursue a film-based strategy, giving them easier and low-cost access to touch technology for flexible displays. In the medium term, IDTechEx envisages that a more diverse range of flexible display products will emerge, each offering a different performance. This will further sustain the existence of multiple approaches in the market.

Note that the battle between film-type vs on (or in)-cell type is also in force in rigid displays. Here too, both approaches are used although, trends can shift the balance one way or the other.
