Now, the latest report is even more exciting, South Korean tech giant, Samsung, has filed a new patent for a phone with an expandable display. According to GizmoChina, the patent shows an expandable display that a user will be able to increase or decrease as per the use.

When folded, it will look like just another smartphone, while the open state of the phone will offer a larger display. 

The patented smartphone is expected to be equipped with a sensor that will be able to recognise the increase or decrease in the size of the display.

If everything goes well Samsung could technically provide a smartphone that offers the benefits of having multiple screen sizes.

It's also worth noting that if it becomes a reality, we could see the technology being used in bigger displays as well. However, this is not the first time we are seeing a smartphone patent with an expandable display.

Xiaomi had also patented a similar smartphone a few months back and it would be interesting to see who comes up with the first device.
