Restore the Real World Samsung Quantum Dots + HDR Technology Analysis

Quantum dots regain new life in LCD TVs

As an old friend of ours, television has undergone several generations of changes. Standing today and returning to our early television products, we will find that there has been a tremendous change from inside to outside. In the long flow of television development, technology has always been the biggest driving force in the development of the television field. All the exploration of peak technology will have a huge impact on the future of television products. As a global TV maker, Samsung has attracted a lot of attention in the industry for every move. In the display technology innovation, Samsung has not stopped the pace of advancement, setting a barometer for the entire industry.
From this year onwards, we can see that TV makers both at home and abroad have placed their development direction on display technology. This also means that the color TV industry has returned to the development track with display technology as its core. Indeed, television is the protagonist of the living room entertainment. If there is no display technology as the foundation, nothing else has any meaning. Samsung has always been a promoter of quantum dot technology. Since the SUHD TV series was launched last year, it has been developing quantum dot display technology.
As the flagship model of 2016, Samsung's second-generation quantum dot TVs have attracted attention as soon as they are available. Among them, the cadmium-free quantum dot materials have become the highlights of second-generation quantum dot TVs. We all know that cadmium is a potentially toxic substance, and cadmium-free quantum dots can also lead to a healthier use environment. At the same time, in terms of image quality performance, Samsung QD TVs use the second-generation quantum dot technology of environmental protection and cadmium-free 10bit. Unlike traditional TVs, quantum dot TVs have a wider color gamut coverage and exhibit excellent high brightness and high contrast. The colors that can be seen are also more abundant, reaching 1 billion species and restoring the most authentic colors.
Samsung's second-generation quantum dot TV has reached the limit of the color and brightness of LCD TVs. In the short-term, there is basically no material that can replace quantum dots. The maturity and environmental protection of quantum dot technology have long been recognized by professional-level manufacturers. More importantly, the lifetime and color life of quantum dots will be longer. At the same time, quantum dot display technology will rejuvenate LCD TVs. Ordinary LCD TVs use the LED backlight module to light up the display layer, and the display layer is extremely complex, including a series of complex components such as glass, polarizers, thin film transistors, liquid crystals, and color filters.

The biggest problem is the LED backlight group. The general LED backlight is a Blu-ray version with phosphoric acid, but the risk of phosphorus is very high. What we see is the white light that passes through the glass panel, but the white light is not pure. The RGB filter will cut off some of the light and convert it into the three primary colors we know, but in reality most filters don't give us good image quality, because it always causes crosstalk and leakage of red, green and blue light.
Quantum dots are no longer a component of TV, but they are completely integrated. This solves the existing problems. Instead, red and green quantum dot tubes are used. After the blue light from the LED is released, these quantum dots will be stimulated before entering the light guide plate, and the red and green quantum dots will fully absorb the light and transform the desired color. The conversion rate may even be close to 100%. This is why Samsung's second-generation quantum dot TV can bring such rich and accurate color.

Quantum Dots + HDR Boost Image Quality to New Heights

Everyone may have felt this year, and our lives have been flooded with various "R"s. The concept of VR, MR, AR and HDR appeared before our eyes. Of course, the concept of HDR is closely related to television display technology. HDR can be said to be the most important display technology after 4K. This year, domestic and foreign TV manufacturers are all working together to develop HDR technology and apply this increasingly fierce display technology to their own flagship products.

HDR breaks the bottleneck in image quality to new heights

HDR can greatly enhance the dynamic range of brightness and improve the short board of brightness under the SDR standard. Here we must share with everyone, the spatial resolution, grayscale resolution, time resolution, color gamut and brightness dynamic range together constitute the color space, and the first four of the five factors have been developed to one The high level, except for the high dynamic range of brightness, is still at a relatively late stage of SDR. As a result, HDR came into being, allowing the picture quality to break through the bottleneck and reach new heights.

The advantages of HDR 1000

Popular point of view, HDR can make the details of the screen highlights and dark details are fully demonstrated, there will be no dead or overexposure. Whether it is the moment of fireworks bloom or the shadow of a tree under the dark, TVs with HDR can clearly reproduce every color and detail, as seen in person. At present, a considerable number of high-end devices can shoot HDR content. The television dramas that were aired some time ago, including the "Yueyue Biography" and "Prince of the Prince", were shot using HDR professional cameras. Moreover, most of the top film and television production companies are also using 1000 nits as a standard for HDR content mastering films.

Black details are not lost

As a result, Samsung's second-generation Quantum-dot TV sets the HDR 1000 industry's highest standards, enabling us to see a new level of brightness and color reproduction of the images we see, with a peak brightness of 1,000 nits. Samsung's second-generation quantum dot-dot TV uses HDR backlighting systems and subtle remodeling engines. The combination of panel-to-backlight-to-decode technology is the core technology of Samsung's second-generation SUHD QDs, plus quantum dot technology. With its natural advantages, Samsung's second-generation Quantum Dot TV has restored the real world for us.
