The progress in OLED (organic light emitting diode) material
in recent years indicates that the following prophecies of Dr. Kaku are likely
to be realized in 2030s.
Computer and Internet on the wall displaying 3-D images
(Family gatherings taking place via wall screens)
Flexible and super-thin electronic OLED paper used
everywhere, reducing laptops to folding and transparent sheets of paper.

Currently, OLED is already the preferred screen used by
high-class portables such as cell phones or other wearable goods. It is also
used for big TV screens such as 55 or 65 inches. Of course, they are rather
expensive now. It is reasonable to assume that the price of OLED will be one
hundredth of the current price in 15 to 20 years. In 2030s, OLED will be used
as wall paper which becomes Internet screens,
or used as folding computers put in the pockets like note books.
