Because of a recent rise in flip phone sales, Apple is once again hinting at the possibility of a foldable phone.
A recently published US Patent and Trademark application from Apple is for "an electronic device (that) may have a flexible portion that allows (it) to be folded."
The patent filed in September 2016 came shortly before Apple was granted a patent for a similar folding device, according to CNNMoney.
According to the patent, the flexible display could be applied to laptops, tablets and watches.
The abstract for the patent says in part:
An electronic device may have a flexible portion that allows the device to be folded. The device may have a flexible display. The flexible display may have a flexible display layer, a cover layer, a touch sensor interposed between the flexible display layer and the cover layer, a support layer, and a polarizer layer. The polarizer layer may be interposed between the touch sensor and the flexible display or between the touch sensor and the cover layer. The touch sensor may include optically clear adhesive that is flexible and facilitates bending of the display.
CNNMoney says Apple often files patents for products that never come to fruition, but documents could provide hints about a future device.
Flip phones became popular in the early 2000s, but PCWorld reports that there has been a recent uptick in sales, especially in Asia.
