Earlier this week, Samsung unveiled its 2016 line of smart televisions in India which includes the SUHD TV range. The SUHD TV or Smart Ultra High Definition TV by Samsung comes with two new key innovations – Quantum Dot Colour and HDR 1000 – which is claimed to offer better colour contrast and vivid viewing experience. But what is Quantum Dot and how does it affect the picture quality? Here's an explainer:
Quantum Dot
Quantum Dots in television technology are extremely tiny particles – smaller than DNA and millions of times smaller than the diameter of human hair - which when exposed to blue light, emit different colours brightly.
The incredible thing about Quantum Displays (QDs) is that they have a longer life span. Unlike the conventional displays, the QDs can maintain their brightness and avoid burn-in for an extended period.
The SUHD TVs with Quantum Dot Colour technology are therefore capable of producing colours as real and life-like as possible. Conventional televisions have an 8-bit panel but the SUHD TV has a 10-bit panel. When the 10-bit panel is layered with Quantum Dot Colour technology, it results in 64 times the colour expression of conventional panels, resulting in 1 billion different colours. The blacks appear darker and the whites brighter because there is no colour overlapping or merging of details. This helps produce the true-to-life UHD effect.
If one compares the Quantum Dot Colour technology with the OLED technology, the major difference lies in the colour reproduction. In OLED TVs, the spectrum of light is broad resulting in more colour mixing and blurry details, while with Quantum Dot Colour technology, the spectrum is very narrow resulting in lesser colour mixing which reproduces purer colours.
HDR or High Dynamic Range – an element borrowed from camera technology – when used in televisions is aimed at delivering content as it was shot. With more and more producers shooting content in HDR, there is a need to make available the required technology that supports the content to its fullest potential. To bridge the gap, the SUHD TVs make use of HDR 1000 along with Quantum Dot Colour technology.
HDR, to put simply, means a merger of the darkest and the brightest shot put together to produce an image that brings out the details sharper than conventional imagery. With HDR 1000, the SUHD TVs are able to display a wide range of luminance, making details visible even in the brightest and the darkest areas of an image. With 1000 nit of brightness, the HDR 1000 technology delivers ultra bright output for detailed images.
