Flexible screen panels are nothing new. It has been around for a long time, which allows the screen of the device to be slightly curved. The latest iteration is, the screen of the device can be folded. We have curved screens, folding screens and the latest being developed by Motorola is a device with a rollable screen.
Samsung is expected to come with the Galaxy Z Roll, BOE is ready to supply screen panels for devices like this, E-Ink already has more or less the same technology, and keep in mind that Oppo once launched the Oppo X 2021 which is the first device with a rollable screen.
The device which is said to be the Motorola Felix will continue the existing concept on the Motorola Razr. It will come with an elongated shape and can roll from top to bottom, unlike the Oppo from the side can be wider. Felix will be long when you want to use and finished rolled will be small and compact for storage and easy access.
The project is still in the early stages of development. Even the prototype that Motorola uses is with a modified Motorola Edge Pro 30 as there is still no full equipment for a device with an elongated scrollable screen.
