Tech watch: The flexible phone

Samsung’s ‘YOUM’ bendable-technology smartphone or tablet screens can start bigger and be rolled up at a moment’s notice

The mobile phone has come a long way in the past 40 years. It was 1984 when the first portable phone, the Motorola DynaTAC 8000X, was released to the public: the mobile cost US$3,995 and weighed nearly a kilogram. It took a further eight years for the first text message to be sent, with the smartphone being introduced another two years later, in 1994.

Now, Samsung’s ‘YOUM’ bendable-technology smartphone or tablet screens are a testament to the rapid development in technology when it comes to smartphones. The device can start big and be rolled up at a moment’s notice.

It is bendable, foldable, rollable: the OLED display is scratch- and shatter-resistant and more durable than the average smartphone. The technology does not use a backlight. It has greater depth in its blacks and a longer battery life.

Samsung’s Brian Berkeley believes the technology could eventually turn objects and surfaces into computers.
