My idea is about replacing the old fashioned wooden blackboard with foldable OLED and calcite chalk with electronic or digital pen.
Foldable OLED can be folded and refolded more or less 100,000 times without picture creases. Foldable OLED is sold in consumer's market but its full use is not yet fully realized.
