TV manufacturers say that their algorithms can accurately select which colors to intensify, but as we already know this is exactly what the movie crew is doing in the studio. A typical red tone will appear much more intense, which was not the intention of the movie producer. By implementing a larger color gamut - from Rec.709 to DCI - all content will be reproduced in the larger color gamut, skewing colors. No manufacturer had actually reached 100% of DCI at the time of CES 2015, but they are quite close.Ī larger color space is by definition good, but there is a catch. Quantum dots can increase the color space of LCD panels from today’s Rec.709 standard, which is a relatively small color space, to 90-98% of the DCI color space, which is the color space used fir movie theatres. However, cadmium will be banned in most markets in the near future and the alternatives - cadmium-free quantum dots - are not nearly as energy efficient, so the screen needs to output more light.īut the most important difference is that 2015 LCD TVs will be able to increase the color space because of the quantum dots. What the manufacturers forgot to tell us is that most power efficiency results in quantum dot research are based on tests with a variant that uses cadmium. It can also improve power efficiency because less light is wasted, but this is more relevant for mobile screens than TV screens. Potentially, this could mean a slight improvement in contrast and color saturation. The light from a quantum dot is "pure" (for TV use) and better suited for picture reproduction. The purpose is to convert blue light from conventional LEDs to saturated primary colors. The color depends on the size of the nano particle. When exposing quantum dots to energy in the form of light the particles become "excited" and can convert light into primary colors. In front of the LEDs - and behind the LCD panel - manufacturers can add the sheet of tiny nano particles. Behind the LCD panel are LEDs (light emitting diodes) either directly behind the LCD panel or along the edges. How it is implemented in LCD TVsSo how do you implement quantum dots in a TV? First and foremost we have to emphasize that these TVs are still LCD TVs. Other TV manufacturers also announced quantum dot TVs, prompted by the threat from OLED. Only one of the two South Korean manufacturers have been able to mass produce the stunning OLED TVs, so Samsung is rolling out plan b. The future looked bright, so Sony’s launch of the W90 was obviously a defensive move. At that time, Samsung and LG exhibited incredible OLED displays. The timing may seem odd, but it is not more surprising now than it was in January 2013. Or to be precise LCD TVs with quantum dots. The tiny dots have since been implemented in the Amazon Kindle Fire in a not-so-successful manner.įast forward to CES 2015 where we saw an avalanche of quantum dot TVs from Samsung, LG, Sony, Panasonic, Sharp, TCL and others. The industry talked about using them for a few years before Sony eventually introduced the first Triluminos TV with quantum dots in January 2013 in the W90 model. Since discovering the small dots, companies have tried to use them to improve - among other things - solar cells, but the idea of using quantum dots to improve TVs came later. It was discovered way back in the early eighties and as the name suggests the dots are tiny nano particles of less than 10 nanometers in diameter. So why now?The quantum dot is not a new invention. TVs with "quantum dots" were everywhere at CES 2015, but is it just more marketing or does the technology offer real improvement? In this article we will explore quantum dots and explain what it means for your TV. MHRA 'US DOT', All Acronyms, 11 November 2022, Bluebook All Acronyms, US DOT (Nov.
