There has been much hype about the arrival of the 5G era, but 4G is still very much alive and kicking. Global smartphone sales have slowed down in 2019, but Taiwanese IC designers have seen demand for 4G smartphone chips rebound in the fourth quarter of the year. At any rate, 5G smartphone demand will shoot up exponentially in 2020, during which more foldable handsets are expected to be made available. Taiwanese firm TPK has disclosed that its nanowire touch solutions has already entered design-in processes of 1-2 foldable phones. For the display industry, the year 2020 does not seem a promising year with fears of panel oversupply lingering. It may have to wait a bit longer before seeing TV panel prices rebound in the second quarter of 2020. But chances are high such a price recovery will be short-lived.
