Bigger Screens

Since my own image of the School of the Future includes lots of computer screen space (so that kids collaborate with workgroups and tutors who are sitting at the same table, but not in the same state), I'm intrigued by the latest on molybdenum disulphide, a graphene-like (2-dimensional) material with a bandgap so it can be used in circuitry more easily than graphene: One-molecule-thick material has big advantages

Palacios says one potential application of the new material is large-screen displays such as television sets and computer monitors, where a separate transistor controls each pixel of the display. Because the material is just one molecule thick -- unlike the highly purified silicon that is used for conventional transistors and must be millions of atoms thick -- even a very large display would use only an infinitesimal quantity of the raw materials. This could potentially reduce cost and weight and improve energy efficiency.
In the future, it could also enable entirely new kinds of devices. The material could be used, in combination with other 2-D materials, to make light-emitting devices. Instead of producing a point source of light from one bulb, an entire wall could be made to glow, producing softer, less glaring light.

Well, maybe nothing whatever will come of molybdenum disulphide. But new things will happen. The HCS classroom of 2032 should be further from the classroom of 2012 than 2012 is from 1912. Yes, really.
