The future of television is here. TV manufacturers have tweaked traditional light-emitting diode (LED) TVs to add an organic (carbon-based) layer that produces coloured light. The key to the technology is its carbon-based organic compound layer -traditional LED screens use several layers to make light and colour, but the new OLED screens use only one. They produce images with better colours that change faster than LEDs. OLED TVs have thinner screens, use less energy, and are less polluting than other TVs.


An OLED display has pixels that are able to make a dot of any colour by mixing red, blue, and green light. Each pixel contains three different OLED molecules that make light of one of these three colours. The quality of colour images is improved because the OLEDs make only the exact colours required, and do not filter them from a white light source like other systems.

The screen of this flexible display contains a layer of OLEDs sandwiched between transparent plastic electrodes. It is flexible enough to bend or twist, and could even be rolled up. Flexible screens like this are being used in curved mobile phones and tablets, where the screen wraps around the edge so messages can be displayed along the side of the device. Flexible OLED displays are even lightweight enough to be stitched on to fabric. As well as displays, OLEDs can produce light of a single colour and be a highly versatile form of low-energy lighting that can be used just about anywhere.

LEDs create 16 million colours by mixing red, green, and blue light oduced by three kinds of chemicals.

Curved Screen

This TV produces a high-definition picture from a layer of OLEDs, or organic light-emitting diodes. That layer is 200 times thinner than a strand of hair, making an OLED screen flexible enough to be curved.
