According to Korea’s Money Today (via SamMobile), the device is being developed by Samsung Electronics, while Samsung Display is in advanced talks to supply the rollable OLED panels.

Market research firm Omdia expects the device to feature a 10-inch rollable OLED display with a 16:9 aspect ratio and a resolution of around 440ppi.

The design is aimed at blurring the line between a premium smartphone and a productivity tablet, offering a larger screen in a compact form factor.

Samsung Display is reportedly pushing to secure early dominance in rollable OLED technology, especially as Chinese competitors strengthen their position in foldable panels.

An industry source cited by Money Today said the company is in discussions to supply panels for a rollable device being developed under Samsung’s Mobile eXperience (MX) division.

Reports suggest the device could be launched under the “Galaxy Z Slide” name, although Samsung has also trademarked “Galaxy Z Roll.”

A Samsung Electronics executive was quoted as saying internal development is underway with a target launch in early 2028, with a strong possibility of using Samsung Display panels.

Samsung has led the foldable smartphone market with its Galaxy Z Fold and Z Flip series and is now expected to extend its innovation push into rollable displays.

The rollout would also mark the 10th anniversary of Samsung’s foldable smartphone lineup, if timelines align.

While Samsung has showcased rollable and stretchable display concepts in the past, mass-market rollable smartphones remain technically complex.

Industry observers note that despite progress, durability and structural engineering challenges mean commercial rollout is still several years away.
