What is an OLED screen?

If you’ve been shopping around for a new TV recently then you might have seen the acronym OLED. It’s being hailed as the next step in the development of TV technology but just what is OLED and what makes it different?

OLED: A definition

OLED stands for organic light emitting diode. Essentially it’s a light source that uses semi-conductor wafers made from organic material. So when electric current is applied to this organic material, it emits energy in the form of light.

It’s the same principle that is used in the standard LED screens, only the more traditional LEDs use solid state semi-conductors. OLEDs use conductors made from organic material in the form of chemical compounds containing carbon and hydrogen.

Why is OLED better?

All of the above technical information is all well and good but what does the theory mean in practice?

OLED screens can be thinner and smaller than LEDs. In fact, every single pixel on the screen is an OLED light and can be controlled individually. Because LEDs can’t be that small, they often use a liquid crystal display screen that’s lit by LEDs. This can often lead to some dilution of colours, and not so sharp black tones.

Using OLED means there is both greater definition and control. The screens can also be more flexible, with better image quality. It also means there is reduced power consumption and faster response times than traditional LED TVs.

Who is making OLED TVs?

Initially just two manufacturers were making OLED – LG and Panasonic. However, recently Sony has re-entered the market with its OLED range. This has helped to bring the cost down and make it more affordable for everyday consumers.

There have been some question marks over the longevity of OLED screens but this is improving all the time. And because OLED technology allows screens to be so much thinner and smaller, they are also using fewer materials in their manufacture. Plus, all of this comes with superior colour definition and response times.

OLED TVs have been on the market since 2012 when Samsung and LG released their models. Samsung since dropped their OLED range, meaning LG was the sole provider.

However, recently Panasonic and now Sony have also caught up. The new Sony Bravia OLED looks pretty incredible, with fantastic colours from more or less any angle. Some OLED TVs also include a 3D capability and because it’s passive, it means cheaper glasses and less screen flicker.
