According to the latest leaks from infamous leaker Evan Blass, the latest LG V30 could actually feature a unique approach to having dual displays.
While Evan Blass states that this is just a conceptual render and that the V30 may not ever end up having this feature, its still a possibility they moved forward with it.

Traditionally, the LG V series has been a dual-display larger flagship device with the V10 and V20 both featuring a smaller 'ticker' style OLED display to show notifications and persistent icons at lower power. However, with this concept, it appears possible that LG has gone with a more unique approach to dual displays with a sliding concept that could theoretically make the display on the phone larger without compromising the size of the device.

While this isn't a bendable display concept, it is still a unique application of the latest display technologies, and it would be fun to see how LG runs with it, if true. LG has experience working with the latest display technologies, and they are one of the few companies capable of innovating in display technologies. These renders were conceptual only, so until we get some actual photos of hardware we are going to just have to hope that LG decided to move forward with this concept in a prototype.
