For all of you endlessly arguing where the future goes with regard to which technology, plasma or LCD, would prevail in the future - the answer could probably be neither! I recently came across a relevant article in MIT's Technology Review magazine, where nano-CRT was portrayed as the way going forward with regard to future TV sets. To briefly explain a conventional CRT works by means of an electron gun, positioned some 20-60 cm behind the screen depending on screen size, that shoots a focused electron beam on a glass screen coated with a suitable material that emits light when shot by electrons. Recent progress in nanotechnology has allowed for the production of very tiny electron guns, in the nano scale of size, arranged one next to the other - like a matrix of pixels in a plasma or LCD set. These nano-guns need only to be a very small distance behind the coated screen glass, since their individual job is to shoot one electron beam at a specific pixel on the screen, rather than covering progressively the entire screen like a conventional electron gun does in today's CRTs. The end result is CRT picture quality with a minimal screen depth, similar or smaller that today's plasma or LCD sets. Another bonus is that the effortless construction technique involved in producing nano-guns allows for the inexpensive manufacturing of very large screens, at minimal extra investment. Working prototypes have been already be developed by several manufacturers and independent researchers, it seem though that Samsung has the lead in this new field. The most severe problem developers face in implementing the new technology is the fact that for a CRT TV to work one has first to create a vacuum inside the CRT tube, otherwise the air molecules will "ignite" and emit light before the electron beam has a chance to hit the coated glass surface. This is relatively easily solved in conventional CRTs by means of the big volume the tube itself presents (like taking a slice off a sphere) which allows for the structure to withstand the immense external pressure created by the vacuum inside the tube. However, a nano-CRT tube is flat, with very little depth, and if a vacuum is created inside the external ambient pressure causes the structure to collapse. Its like stepping with all your weight on a flat pizza box! So, until someone finds a way to economically solve this apparent problem, plasma and LCDs will be kings. Afterwards ... long live nano-CRT!
