Organic light-emitting diodes is a rather odd name for a new generation of displays. It promises better pictures, lower power consumption and thinner lighter screens - but it also comes at a price.
Current day televisions have come along in leaps and bounds over the last decade and offer a vast array of sizes and specifications.
But there are some problems: the images take longer to fade from the screen, occasionally giving a vaguely blurry feel and the ratio of light to dark areas on the screen - known as the contrast ratio - is not as good as it could be.
OLED on the other hand has manufacturers claiming a contrast ratio of 1,000,000:1 which is astronomical - the colours really are breathtakingly vivid - and the screens fantastically thin.
The image is visible from extreme angles - something else traditional TVs have trouble doing.
Here is the but: the 11 inch Sony screens are $2,500 (£1,300) each and the company is tight-lipped about the price of its bigger screen.
Another OLED player is Samsung which has announced it will be shipping OLEDs soon; there is no doubt that these too are going to be expensive.
