What Is A Quantum Dot?

Amazon’s Kindle Fire HDX7 was the result of its work with Milpitas, which in turn is a part of Nanosys. Amazon has always wanted to produce display screen that have vibrant colors in their tablet displays and are low on power consumption. Amazon’s Kindle Fire HDX7 was a very, very big hit due to this rich color reproduction ability.

Amazon uses, what is called, Quantum Dots in their Kindle Fire range of tablets. Quantum Dots are, basically, semiconductor crystals that are 10,000 times thinner and lighter than the human hair. Light is generated using electrical energy. This light then helps in the production of colors in the visible spectrum using Quantum Dots.

Nowadays, many manufacturers are tying up or collaborating with display manufacturers to develop newer displays for their respective products. Demand for Quantum Dots is very high. Quantum Dots consume less power and are cheaper when comparing with Organic Light-Emitting Diodes (OLED). The downside is that Quantum Dots cannot be produced in high quantities like OLEDs.

Some manufacturers use Cadmium to produce Quantum Dots even though the mineral is restricted in many countries. DisplayMate Technologies conducted a recent survey, which found that Amazon’s Fire HDX7 display was far superior to that of the Google Nexus 7 and even the Apple iPad Mini Retina.

The Quantum Dots technology has been in research and development since the 1980s. It has only been out of the laboratories for the last decade. There have been numerous partnerships going on in the field of display technologies. The process of manufacturing OLEDs for use in large screen TVs is very expensive when you compare it to Quantum Dots manufacturing.

Another major concern for this technology (Quantum Dots) to prosper is the patent arena. The patents create a bottleneck for it to develop and prosper and increase the price of the displays.
