Until recently, most high-quality color reproduction in the case of liquid crystal displays were only if the lights carried RGB-LEDs in triads. But it is very expensive and hot. To reduce the display without significant loss in gamut RGB-light zone was made. Then were invented quantum dots. This is when the backlight is responsible for not the traditional blue or blue with yellow phosphor LED, and a color filter having a pronounced clean transmission spectrum of light. Specifically, such a filter has two peaks - a red and green ranges. Differently - originally blue radiation excites two pure color filter and fine-tuned in the production of color: red and green. The result is a wider color gamut resulting images on the screen (up to 50% brighter). Quantum dots also have gone from a solid array RGB-to zonal side illumination. It is cheaper, although give slightly worse result.
While the display is based on quantum dots wide released by Sony. They are sold under the brand Triluminos. These displays are offered not only for TV, but also for smartphones and tablets. EtNews edition reports that the color filters using quantum dots are ready to release Samsung, LG and Hanwha L & C company. Now the production is being experienced. Mass production of the new filters and LCD-panels based on them is expected in the second half of this year. However, the source notes that there are problems with getting the license, as the technology of quantum dots is considered an American invention. At the same time, South Korean companies last few years engaged in their own research on the subject. For example, Samsung is interested in creating an array of quantum dots based on OLED.
