In February 2019, Hewlett-Packard Development filed a patent application with the World Intellectual Property Office. The patent, called “Electronic Display Devices”, was approved on August 13, 2020 and describes the technology needed to implement a flexible electronic display in mobile devices.
The patent images show a folding phone (similar to the Motorola RAZR and Samsung Galaxy Z Flip) with a wide hinge. Using patent images, resource LetsGoDigital has created a series of 3D-renders, which allow you to better view the device.
Folding phone from HP has a flat bending screen, made by technology OLED. The documentation describes the problems associated with using the flexible display. When folded, the length of the inner surface changes relative to the outer surface. This means that there is a risk that even the flexible display will be damaged if the smartphone is actively used.
To solve this problem, HP wants to use a stretchable structure that becomes thicker under pressure.
Unfortunately, all you saw above is a prototype. The date of the new product release and prices are still unknown. Recall that after the release of the model Elite X3 company HP has not released a new smartphone. The main reason for this was the decline of the Windows Phone platform.
