Apple Patent Application Reveals Deep Interest In Quantum-Dot Display Technology
by István Fekete – 1 year agoJuly 29, 2016 at 12:27 pm
When it comes to the 2017 iPhone, sources agree that Apple will use OLED display. That, however, doesn’t stop the company from exploring other technologies and the Quantum Dot LED or QLED, which is similar to OLED, is theoretically able to deliver more vibrant colours, and consume close to 50% less power than its OLED counterpart.
Because of this, Apple is very interested in the technology. Plus, it also has the potential to be used in a display that could wrap around your wrist like a watch band. Patently Apple has spotted Apple’s patent application 20160218252 for “Display Light Sources With Quantum Dots,” which as described in the abstract, generally relates to electronic devices with displays and displays’ light sources.

A display may be provided with light sources. The light sources may include light-emitting diodes. The light sources may have packages formed from package bodies to which the light-emitting diodes are mounted. Layers such as quantum dot layers, light-scattering layers, spacer layers, and diffusion barrier layers may be formed over the package bodies and light-emitting diodes. Quantum dots of different colors may be stacked on top of each other. A getter may be incorporated into one or more of the layers to getter oxygen and water. Quantum dots may be formed from semiconductor layers that are doped with n-type and p-type dopant to adjust the locations of their conduction and valance bands and thereby enhanced quantum dot performance.

Over 30% of Smartphones Shipped in 2018 to Carry OLED Panel as iPhone X Revealed, TrendForce Says
OLED TVs are going to be in a dominant position in the high-end segment until the second half of 2018, when the mass production of next-generation QLED panels is expected to begin.

Apple is looking into ‘true’ quantum dot displays
August 03, 2017/ Dennis Sellers
Apple has filed for a patent (number 20170221969) for “Quantum dot LED and OLED integration for high efficiency displays,” which promises quantum dot pixel displays on all its devices . The displays would offer “pure color” and use less energy.

Apple proposes combining OLED technology with quantum dots
Aug 4, 2017
Apple wrote and added: “Even more recently, quantum dot light emitting diodes (QD-LEDs) have been introduced as an alternative display technology , potentially being more power efficient that OLEDs.”

Apple's Fourth Invention Covering Next-Gen Quantum Dot Displays surfaced today at the U.S. Patent Office
To date Patently Apple has posted three patent reports regarding Apple's possible use of quantum dot displays. The first report was posted in February 2014, the second in July 2016 and the third last month titled " Apple Invents Quantum Dot Hybrid Pixels for Future Power Efficient Displays that Could Deliver 'Pure Color' ." Quantum dot QD-LED displays will offer better power efficiency than OLED alone. Today the US Patent & Trademark Office published yet another patent application on this subject matter titled " Quantum Dot Spacing for High Efficiency Quantum Dot LED Displays ."

QLED is very similiar to the OLED technology. But the difference is that the light emitting centers are cadmium selenide (CdSe) nanocrystals, or quantum dots.
...each quantum dot includes a core, a shell around the core, and a metal oxide coating around the shell

According to Levy, “Apple rejected [Quantum Dot] because it required cadmium, a toxic element,”

Technavio analysts highlight the following three factors that are contributing to the growth of the global quantum dots market :
• Increasing demand for 4K UHD TVs
• Growing interest in cadmium-free quantum dots
• Requirement for energy-efficient devices
cadmium-free quantum dots by vendors such as Dow Chemical Company, Nanoco, Nanosys, and Quantum Materials
Governments are looking for more eco-friendly sources of energy and efficient devices to cut down on the total energy consumption and combat global warming.
“ Quantum dots are highly energy efficient, which makes it extremely suitable to be used in energy efficient consumer electronic devices. It needs 30% lesser power to work , which not only saves energy but also extends the life of the device on a single charge ,” says Sunil, explaining the factors pushing for the increasing adoption of QD in electronic devices.

Apple reportedly signs two year deal with Samsung to supply curved iPhone OLED displays, up to 92 million panels in 2017
Apple reportedly has signed a two-year contract with Samsung Display for the supply of KRW10 trillion (US$9 billion) worth of small-size curved OLED panels, according to Korea-based ET News, Chosun Bizand other media.

....the curved screens only represent about 30% of Apple's 200 Million iPhone devices/yr

......of those mentioned how many could meet the needs of TV Displays...and APPLE's Hybrid Oled? I noticed that Apple's Hybrid just seem to use the BLUE QD......didn't QMC recently get a patent wrt Blue QDs and have some testing going on...and a RED Cadmium-free QD w/a 99+% QY?
Maybe micro-leds will leap-frog some of the QD-Led applications, maybe not. Either way I think QMC is well positioned

“ We have begun continuous-flow volume production of high-efficiency blue quantum dots that we believe will play an important role in the future of quantum dot light-emitting diodes (QD-LEDs). Prior to this point, blue quantum dots exhibited unfavorable energy levels in comparison to red and green quantum dots with respect to device efficiency,”
