Lenovo has debuted technology for smartphones and laptops that expands the screen on request at its own Tech World 2022 event.
To make this happen, Lenovo is using rollable screen technology.
The flexible OLED panels can be rolled up inside a smartphone or
laptop like a scroll, and then unfurled to expand the screen.
The smartphone proof of concept shows the screen expanding from its
normal state (4-in diagonal) to 6.5-in diagonal screen with the push of
a button.
At present the two devices are merely proofs of
concept, so it is not definite whether they will made commercially
avalable yet. The challenges lie in making the devices affordable and preventing
the rollable screen technology from deteriorating over time due to repeated use.
