Graphene-based Quantum Dots – GODs of TV

While watching television, most viewers would be happy to have a flat-screen with a wide viewing angel and vivid, life-like colors. Most viewers would say they want these characteristics in HD formatting for clarity. As television technologies evolve, viewers are getting their wish, with flat-screen LCD, Plasma, LED and OLED sets.

To meet the demand in a media-based society, television manufacturers are partnering with mobile device producers, giving their customers these benefits on iPhones, SmartPhones and various other devices. These technologies are even making their way into games for dedicated gamers to enjoy.

Plasma, LCD and LED sets all have their benefits, but it seems that OLED sets are a viewer favorite. These sets offer the widest viewing angels, with superior color quality than other sets can offer. These sets are more environment-friendly, using organic materials, and take less energy to operate. These sets are in demand to the point that experts predict they will be the next industry standard. This is pushing television manufacturers to develop and include OLED technologies in all their products. Television manufacturers are even applying OLED technology to newer 3DTV sets.

It has been predicted that, over the next decade, consumers will see the integration of OLED screens and their applications continue to make their ways into the homes of the average family.

The main complaint for the average household is the investment required for even a smaller OLED television. Due to the technology and development that goes into a screen that is the width of three credit cards, with a picture that out-shines anything else available on the current market, OLED screens can be extremely expensive.

However, due to new developments out of New Delhi, India, consumers may see a ceiling on these prices, shortly. New Delhi, India is the home of the National Physical Laboratory. The scientists there are happy to announce their newest development, graphene-based quantum dots.

Graphene-based quantum dots, or GQDs, are non-toxic, keeping the integrity of the organic aspect of the OLED set. OLED sets do not contain cadmium. Cadmium has been banned in most parts of the world, so with a cadmium-free quantum dot, this development is commercially viable for most any location in the world. This lends even more accessibility and affordability to manufacturers that can pass the savings to their customers.

Besides the added affordability and accessibility, manufacturers like the technical benefits of increased efficiency, and the decrease of electricity that GQDs offer. With this development, quantum dots can use less electricity than even current OLED sets require.

Basically, quantum dots are semi-conductors. This work currently has applications for OLED technology and for solar cells.

Work with graphene quantum dots is being watched with anticipation. When developers have perfected them, they can be used in broader applications, allowing for cheaper OLED panels, lowering the price for the average consumer. GQDs could make OLED screens less expensive, more mobile and adaptable. GQD has also been credited with making OLED screens more bendable and lighter. With the ability to mass-produce GQD OLED, consumers could be able to enjoy the benefits and reduced cost, shortly.
