What is an OLED TV?

While OLED technology has been used in smartphone screens for some time now, it's a relatively new addition to the world of TVs. It stands for 'Organic Light Emitting Diode' and the main difference is that the screen isn't backlit, like a standard LED TV - instead, each pixel is controlled separately by sending an electrical current to it. 

What's the difference between LED and LCD?

When you see LED or LCD, it's usually describing the same type of TV – LED (Light Emitting Diode) is the light source that sits behind the LCD (Liquid Crystal Display), and is the reason why OLED screens can be made much thinner.

At the moment, an OLED TV will cost a bit more than its LED counterpart, but prices have dropped dramatically over the last couple of years. In 2015, a 55 inch OLED TV would have cost at least £3000, with some prices now starting at half that - like the outstanding 55 inch LG C7.

The benefits that OLED offers means it's definitely a technology that's here to stay.

So what's best - LED or OLED?

Like many thngs, it largely comes down to personal preference - both technologies can offer super high resolition 4K images with good viewing angles, high refresh rates, and excellent contrast ratios. But there are a few things that OLED TVs do just that little bit better:

True blacks

The more electrical current that's sent to the pixel, the brighter it gets. This means that the pixel can also be switched off altogether to create absolute blacks and a higher contrast ratio - and not even the best LED screens can do that.

Ultra-thin screens

Because there's no need for the screen to be backlit using an LED panel, they can be very thin indeed. The LG OLED W for example, is just 4mm thick - that's thinner than a digestive biscuit!

Better viewing angles

Because of the way OLED works, it means the viewing angles are far better than LED screens, with almost no loss of colour or contrast at the widest angles.

More energy efficient

LED TVs need the backlight to be on all the time and the LCD pixels either let the light through, or block it - OLED screens do away with the backlight altogether. Instead, they just send power to the individual pixels to turn them on, which uses less energy.

None of this means that standard LED TVs will become obsolete any time soon, but OLED is certainly closing the gap. You can take a look at our full range of OLED TVs here.
