IT Home December 25 news, according to MSPoweruser reported that in recent years, Samsung has been developing a folding screen smartphone with two hinges and three panels, and we even saw a prototype from Samsung Display.
There is now more evidence that Samsung is seriously studying the device, which is based on a very detailed patent discovered by LetsGoDigital.
IT House has learned that the patent shows that the device has the two hinges mentioned above, three screen windows, but also has some details, such as a three-lens camera on the back, an additional display for selfies taken with the main camera on the back, an in-screen fingerprint reader, an off-screen selfie lens, and USB and HDMI interfaces.
The illustration also shows dual batteries and dual antennas for better reception of signals.
Below is a rendering of the associated device.
The advantage of a tri-fold smartphone is that it does not require an external screen and can be expanded to a larger size, but of course it is much thicker and heavier than ordinary smartphones.
