Samsung explores sliding screen phones: freely switch between wide and long flat screens.
According to a report by blogger “iIceUniverse” on November 10th, Samsung is exploring a sliding screen phone with a screen ratio that can switch between 16:9 and 21:9, allowing users to choose between a wide or long flat screen.
The patent corresponding to this approach has been published. Samsung filed a design patent with the U.S. Patent and Trademark Office last month, number 2026/0333595 A1, which is implemented by extending the display screen by pulling the body upward.
The device is divided into two separable parts, upper and lower. Normally, you hold the lower part, and when you need to expand it, you pull the upper part out. The rear camera and flash are located in the upper part, while the lower part has a camera opening, so you can still take pictures even when the screen is completely folded up.
The fully retracted screen layout is very similar to that of the Galaxy Z Fold8. It is expected that Samsung will continue with the current screen ratio in the short term. Another version of the design that Samsung applied for previously was to unfold horizontally like the Z Fold8 Ultra.
Samsung showcased a rollable screen prototype at MWC 2026 earlier this year, with a form factor almost identical to this patent, differing only in some details. This design is highly likely to be used in next year’s products.
Reports indicate that Samsung plans to release this rollable-screen phone, tentatively named Z Slide, next year alongside the Z Fold9 and Z Fold9 Ultra, with an expected price higher than the two foldable models.
Of course, the final experience of this new form is closely related to an application ecosystem, and the current iPhone Duo is a prime example.
Rollable screens can take on various sizes and proportions during expansion, requiring the interface to adjust accordingly, making them more complex than the two proportions of foldable screens.
