The quest for the best TV picture possible has been a long one, stretching back to the early days of cathode ray tubes and muddy black and white pictures on small and, compared with even the worst of today's TV's, grainy screens.
Then we had colour and, decades later, high definition, both of which were game changers. The next game changer was the evolution from big, fat and heavy CRT's to liquid crystal, or LCD – the flat screens that have freed up space in our viewing rooms while also offering us better quality and larger pictures. LCD evolved to LED, which are really LCD panels with different "back lighting."
Now there are two new technologies vying for your after tax dollars, one of which is a logical next step in the high definition evolution – 4K – and one of which is an absolutely ground breaking leap in picture technology: OLED.
