Samsung's flagship phones might find a whole new way to fold soon
The latest leaks and teasers suggest that the Samsung hinged devices of the immediate future will still have external displays. For example, a recent tip points to a Galaxy Z Fold3 with a more compact 7-inch main display and a 4-inch secondary screen.
Furthermore, there may be a "Z Fold Lite" - possibly the long-awaited first-gen "affordable" foldable from this OEM - with the same dimensions, although its own primary screen may have a more fragile CPI coating rather than the UTG (a protective layer for this foldable's new and supposedly ultra-thin LTPO TFT panel) expected for its putative flagship counterpart.
Finally, the second-gen Galaxy Z Flip is now projected to remain on 6.7 inches for its own flexible display, although a larger 3-inch panel for its exterior surface may be in the offing.
While those putative specs would be welcome improvements, the South Korean giant may be working on something even better for these hypothetical devices' successors. They involve new patented designs for what could be called "tri-folding" versions of the Z Fxxx series.
They involve displays that fold inward at 2 points rather that simply down the middle as with current models. This implies a number of advantages, not the least that it requires just 1 quad rear camera array per device, as two-thirds of their single display can act as the "selfie screen" for this use-case.
Furthermore, it means that the same screen is completely protected when the device is collapsed and pocketed. Then again, as Samsung has only filed this new IP with the United States Patent and Trademarks Office (USPTO) in May 2020, it may be some time before it takes over for the next kind of Z Fold or Flip hinted at in Samsung's latest trailers.
