In Las Vegas will host the international exhibition of household appliances. It is there that LG Electronics will introduce the new Ultra HD TVs. The development includes one feature of the technology of quantum dots. Models have a wide color palette, the color is much more intense than the one that give LCD-TVs.

While the company offers two TVs with a diagonal of 55 and 65 inches. The main difference of the news – technology quantum dots works by connecting nanocrystals. Their size varies from 2 to 10 nanometers. Depending on size, each pixel emits its own color.
According to the company, the performance of color has been enhanced with the addition of a film of quantum dots in front of the LCD backlight. The digital value of the color increased by 30%.

It is also important that the technology of quantum dots allows you to make TVs are safe for the environment. Cadmium and other heavy metals in the production of these models are not used. By the way, Samsung is planning to use this technology and in the manufacture of its equipment.

New technologies in medicine - elastic oximeter
For measuring heart rate and oxygen level in the blood, scientists at the University of California has developed flexible oximeter. Everyone knows that the current instruments for measurements tend to be cumbersome, it is not very convenient to use, which cannot be said about the new development. Externally the new oximeter resembles a band-aid. It is thin and elastic. In order to identify appropriate indicators, the oximeter is equipped with red and green OLED elements. Traditional devices use only red and green light.
As seen, the advantage of the new oximeter is not only a convenience. This kind of organic electronics significantly reduces the cost of production of traditional instruments. Undoubtedly, elastic “oximeter-patch” have already been tested and have shown results with the same accuracy, which provide devices obsolete pattern.
