Tech company Sharp has produced the first commercial 8K television which will show three dimensional images.

The technology is to be targeted at broadcasters and those interested in testing the format.  

Tech consultant Chris Green told the BBC that 8K screens could provide "a very interesting video alternative to today's shop window and billboard display."

Viewers will not have to wear 3D glasses, as the pixels in the screen will make the images appear three dimensional. 

The NAB trade show, held every April in Las Vegas, used to bill itself as the place to see kit manufacturers parade their newest wares to broadcasters and producers. Headline-grabbing black boxes that perform cool, new tricks are, however, increasingly rare.

Today's production and post-­production tools tend, instead, to be software. They are, therefore, open to incremental and regular upgrades, and not tied to the cycle of trade shows.

Even the hardware is designed to evolve with tweaks to the central chip set, rather than a wholesale ­redesign.
