The clearest, brightest, sharpest picture ever

OLED (Organic Light Emitting Diode) TVs are the next step in display technology. OLED takes picture clarity up a notch, being more vibrant than LED and featuring faster response times than plasma. It also creates more realistic blacks than both technologies, as well as being more energy efficient. OLED is more flexible too, which has seen some manufacturers experiment with curved displays for better viewing angles.

How does it work?

In LED and LCD TVs, white back or edge lighting shines through LCD shutters. With OLED, each pixel on the screen features a red, green or blue light source that self-illuminates when a current passes through it.

The benefits:

First off, OLED is more responsive than LCD, LED and plasma, so moving images are a lot smoother. LED and LCD also suffer from constant lighting that can spoil contrast and how black displays. With OLED, the light source in each pixel switches on and off independently, leading to darker blacks and TVs that are much less power hungry.

This precision lighting creates more sharply defined colours and because there's no back or edge lighting, TVs can be thinner and lighter.
