Based on Shape Memory Technology – a concept whereby metals expand and contract to retain the original shape – the phone’s screen has grid of pins. These pins move up and down as required thereby elevating or depressing the display based on the text or display to be represented. The concept took around 3 years to materialize and with the validation and iteration stage receiving a great response the prototyping is currently going on.
