LG's patent for a foldable phone shows device has two screens, batteries and headphone jacks9
The images that accompany the filing show hinges at the top and bottom of the device which allow the two individual screens to open and combine to form one large display. When the device is folded, the two screens can be used independently of each other. In one mode, the two displays can be used to simulate a book as the user reads through one screen, turning to the second one as though he were going from page to page. When the device is partially folded, two people can watch different videos at the same time, with each using their own headphone jack to hear the audio in private. Even though the patent application was filed in 2016, the first screen features an under-display fingerprint scanner, and both housings feature their own digital camera and their own battery.
So add LG to the list of companies that have patented a version of a foldable phone or tablet. Just recently we added Huawei to the list along with Samsung, Apple and Microsoft. The foldable Samsung Galaxy X could be unveiled early next year. LG is apparently making its foldable phone a multimedia focused device that will allow two people to view (and listen to) different videos at the same time without disturbing each other (see the image at the top of this story).
