QLED Out-shines OLED in CES Automotive Display Demo

Ken Werner, writing for DisplayDaily, talks about Harman's new innovative use of quantum dot displays for high end automotive applications. In a CES 2018 demonstration, a QLED quantum dot display was paired with an OLED display inside a dark Maserati and the QLED display with local dimming did not show any sign of visual mismatch against the OLED. 

"Rashmi Rao, Harman Senior Director of Advanced Systems and User Experience, explained that for a high-end car like the Maserati, Harman selected the best-performing display technology for the critical instrument cluster, while the large QLED display still offers very good performance at a significantly lower cost than OLED. Rao commented that the QLED does a good job of integrating visually with the OLED. A conventional LCD would present an obvious visual mismatch with the OLED. The system in the Maserati was fully functional but is not yet in a shipping automobile."

4K.com: How Electro Quantum Dots Might Crush OLED In 4K TVs & Other Devices

Stephan Jukic from 4K.com 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.”

Display Daily: Quantum Dot Display Technology Coming to LCD's Rescue

Sweta Dash from DisplayDaily explains how Quantum Dots are enabling LCDs to match or even out perform competitors by providing higher peak brightness, wider color gamut and better image quality. These are all the crucial requirements for the best UltraHD HDR experience:

"After CCFL-based TV sets reached market maturity and growth slowed down, LED-based LCD TV created a growth cycle by boosting replacement demand. The winning formula was “good enough picture quality” with “competitive price”. It not only changed the TV market, it also spilled over to all other application markets such as monitor, notebook, industrial, medical and others and that strengthened the LCD technology and production base. Quantum dot technology has the same potential to enable LCD to create a growth cycle and drive replacement demand.

TV manufacturers are shifting to higher resolutions to offer better picture quality. But adoption of WCG and HDR with 4K resolutions really helped consumer to see the visual quality differences and experience it. Quantum dot enhanced backlight light in LCD TV takes it to the next level with an even wider range of colors and luminance."

Electro Optics: Quantum Dots Enabling A New Era of Color

As display resolution reaches a point of diminishing returns display makers are turning their focus to wide color gamut and pixel quality as the next step for display development. Matthew Dale of ElectoOptics recently spoke with analyst Eric Virey of Yole Developpment and Nanosys' Jeff Yurek for an update on next generation materials technologies that are enabling a new era in color for displays:

"‘Quantum dots are able to achieve higher peak brightness, lower energy consumption, slightly wider colour gamut and better colour volume [than OLEDs] – the ability to render all the colours perfectly at any level of brightness,’ Virey explained.

This competitive performance, combined with minimal capital investment, an ease of implementation and an upcoming period of constrained manufacturing for OLED televisions, could lead to a dramatic increase in uptake of quantum dot LCD (QLCD/QLED) televisions worldwide in the near future. Yole expects quantum dot televisions to capture the lion’s share of the WCG market over the next five years."

Yole Développement: Quantum Dot Displays Set to Lead Wide Colour Gamut TV Market

According to Yole Développement, Quantum Dot TVs are set to dominate and lead the wide color gamut TV market. Driven by the availability of high volume QD production from Nanosys and it's extended supply chain, TV makers can rapidly adopt the benefits of Quantum Dots

"With the rapidly improving performance and decreasing cost of quantum dots, enhanced LCD displays will be able to take advantage of an upcoming window of limited production for organic LED (OLED) displays – the other main contender capable of delivering wide colour gamut and high dynamic range – and become widely adopted in mid-high range television displays, thus capturing the majority of the wide colour gamut TV market.

OLEDs require the building of entire new production facilities to incorporate into televisions, creating high cost and technology barriers that make it challenging for companies to enter OLED television panel production."

Forbes: QLED Not OLED Is The Future Of TV Technology

Forbes contributor John Archer breaks down the numbers behind the current TV Tech War with help from veteran display analyst Ross Young

"Delving deeper into some of the reasons why DSCC sees OLED struggling so much over the next few years, the report states that OLED TV production techniques are lagging significantly behind QLED ones. QLED lines running to the so-called 10.5G specification are estimated to be as much as two years ahead of 10.5G OLED lines - a big deal when you consider that 10.5G lines are optimized for production of the 65-inch and 75-inch screens expected to become an increasingly key part of the TV market in the next few years."
