When you say board games we all immediately think of games with cardboard and lots of little pieces like Monopoly that have been around for decades. In the future board games might not be what many of us know them as with a new OLED technology that has been developed.
The new tech was developed at the Queen's University in Ontario, Canada and created a board game where each piece is its own small OLED screen. The pieces look like white cardboard hexagons and an overhead projector is used to display images on the little pieces.
Before you get all excited and start digging out your old Dungeons and Dragons rule books, the tech is still 5-10 years down the road. It will take that long for the thin-film OLED screens needed to become practical.
