No more creases! Patent deals with tricky problem with foldable phones, notably creases in the screen
Motorola has filed a patent that could solve one of the biggest problems with upcoming foldable phones.
Foldable phones with flexible screens are currently being tested and prototyped by a number of tech firms, as a possible smartphone solution for the future.
But the biggest problem that foldable phones have to overcome is what to do about the fact that the screen will be repeatedly folded in half, as this is highly likely to leave a visible crease in the screen.
In the patent Motorola describes a ‘method to recover permanent set in a foldable display’.
Motorola’s solution makes use of a thermal element and sensors built into the foldable part of the device.
The idea is that these sensors detect when the device is completely flat with the screen off. The thermal element is then activated to heat the hinge and remove the crease.
Motorola reportedly calls this ‘semi-permanent deformation’.
The idea of foldable phones is not as far fetched as some may think, as a number of tech giants are exploring this option.
But more likely foldable devices could emerge from the likes of Samsung or LG.
The ‘project valley’ device is able to folded in two to be carried around, with screens on both sides.
LG on the hand has revealed a concept “Active Bending” device featuring an edge-to-edge curved display, and have previously released the G Flex 2 smartphone, which sported a curved build designed to fit into a user’s hand.
