Posts tagged Electro Emissive How Electro Quantum Dots Might Crush OLED In 4K TVs & Other Devices

Stephan Jukic from talks about how Nanosys Electro Luminescent Quantum Dots has to potential to crush OLED TVs and other devices.

"Nanosys calls this technology Electro Luminescent Quantum Dot display (ELQD) and it believes that their development will completely disrupt the current television display industry, in which OLED dominates as far as sheer advancement goes.

These new ELQD displays will in fact work a bit like OLED screens in that they won’t require a backlight of any kind but they’ll create a further advantage due to their superior color palette creation ability –to a degree even higher than that achievable by OLED. At the same time, because each QD subpixel inside such screens will be capable of individual activation/deactivation, ELQD screens will deliver the same perfect blacks, pixel-perfect local dimming and wide viewing angles as those achieved by OLED screens today. Another benefit of such pixel luminance efficiency would be lower overall power consumption, since relatively inefficient, broadly luminous LED backlights can (literally) be removed from the picture.

Circuit Cellar: Nanosys Quantum Dot Technology Makes Low-Cost Printing Displays a Reality

Taiwanese tech magazine, Circuit Cellar, looks at how next-generation electroluminescent Quantum Dot technology can fulfill the promise of OLED:

[Translation] While OLED is still working to push their blues to the required level, quantum dot technology has already proven that it is a better luminescent material for this application. Unlike OLED, quantum dots can produce the required blue light without any physical limitations. Also, quantum dots are made of durable inorganic material to provide better stability under oxygen and water vapor. [...]

This technology may take up to three to five years to commercialize. Nanosys is currently working on reducing the cost and finding a way to make it compatible standard materials. To achieve this, Nanosys will not be using the standard semiconductor manufacturing process for this application and instead, they will be using inkjet-printing.”

What Does the Future of TV Tech Look Like?

The annual CE Week TV Shootout is right around the corner. As a preview to that event Rob Scott at Dealerscope met up with display calibration expert Kevin Miller to talk TV tech trends. Quantum dots were part of the conversation of course:

"As far as a new innovative display technology is concerned, the next big development in LCD display technology is Photo Emissive LCD using Quantum Dots. The Blue backlight shines through the LCD panels to stimulate Red and Green Quantum Dots that then create the Red, Green, and Blue light, which eliminates color filters, and should improve off angle viewing, and dramatically increase energy efficiency... There is one very interesting display technology that companies like Nanosys are working on called Electro luminescent (Electro Emissive), which has great potential, because it will eliminate the LCD panels."

HD Guru: New Quantum Dot Ultra HDTV Flavors On The Way from Nanosys

At CES, Nanosys announced 25 new products across a host of brands...

Meanwhile, the company also discussed next generation quantum dot solutions, and even demonstrated a forthcoming quantum dot color filter replacement technology for the first time. Nanosys calls this color-filter approach “Photo-Emissive” quantum dots, and it’s poised to revolutionize future generations of LED LCD TVs by allowing existing quantum dot tech “to effectively double the efficiency of an LCD, bringing better benefits to not only LED LCD TVs but to OLED, WOLED or microLED displays as well.
