Canon Quantum dots will allow OLED panels to be produced without the need for rare metals
Canon has made a groundbreaking leap in organic light-emitting diode (OLED) technology by developing innovative materials that eliminate the need for rare metals. This remarkable achievement not only demonstrates Canon's commitment to reducing reliance on major rare metal producers, particularly in China but also sets the stage for stable production without geopolitical risks.
With their sights set on commercializing this breakthrough technology within the next few years, Canon is poised to transform the landscape of high-end displays.
Quantum dots are a game-changing material for OLED panels
Canon's latest development revolves around the integration of quantum dots (QD), tiny semiconductor particles with a diameter of just 1 nanometer. These remarkable particles emit vibrant and immersive colors when stimulated by light or an electric current.
Quantum dots have already found application in high-end OLED televisions, but Canon's innovation takes it a step further by utilizing a rare metal-free material.
Reducing dependence on rare metals
By opting for the lead as a key component in their quantum dot OLED panels, Canon addresses the growing concerns surrounding the availability of rare metals, particularly indium, which is predominantly sourced from China. Indium phosphide, a compound widely used by Samsung Electronics in mass-produced quantum dot displays, relies heavily on scarce indium reserves.
Canon's approach, on the other hand, capitalizes on lead, an easily procurable resource obtained from recycled materials in urban mines. This not only ensures a more sustainable supply chain but also mitigates geopolitical risks associated with rare metal procurement.
What will quantum dots change?
Canon's expertise in material composition has allowed them to overcome the durability challenge typically associated with using lead instead of indium. By leveraging their knowledge in compounding materials, such as toner and ink for office equipment, Canon has successfully developed a compound that matches the longevity and reliability of indium.
The integration of quantum dots into OLED panels offers numerous advantages, including vivid and evenly bright red and green hues, even under well-lit conditions. Additionally, power consumption is significantly reduced, making these displays approximately one-third more energy-efficient than conventional screens.
The expected impact on the market
The quantum dots market is projected to experience exponential growth, with Global Information forecasting a market value of $21.1 billion by 2027, representing a 4.1-fold increase compared to 2021. Furthermore, Omdia predicts a significant surge in the number of televisions equipped with quantum dots, estimating that it will surpass 22 million units by 2025, accounting for approximately 8% of the total television market.
The introduction of Canon's rare metal-free quantum dot materials holds great promise for reshaping the high-end television market and making advanced display technology more accessible to consumers.

Martin, I would appreciate that you do not censor this post, as it’s informative writing.
Onur, there is a misleading statement “[…] GIFs are animated images …”. No, obviously you don’t seem to have take much notice of what you were told back in March regarding; Graphics Interchange Format (GIF).
For example, https://www.ghacks.net/2023/03/31/whats-gif-explanation-and-how-to-use-it/#comment-4562919 (if you had read my replies within that thread, you might have learnt something useful). I even mentioned, “GIF intrinsically supports animated images (GIF89a)”.
You linked to said article, [Related: …] within this article, but have somehow failed to take onboard what support you were given by several more knowledgeable people.
If you used AI to help write this article, it has failed miserably.
AI is stupid, and it will not get any better if we really know how this all works. Prove me wrong.. https://www.youtube.com/watch?v=4IYl1sTIOHI
Martin, [#comment-4569908] is only meant to be in: [https://www.ghacks.net/2023/07/09/how-to-send-gifs-on-iphone-two-different-ways/]. Whereas it appears duplicated in several recent random low-quality non relevant articles.
Obviously it [#comment-4569908] was posted: 9 July 2023. Long before this thread even existed… your database is falling over. Those comments are supposed to have unique ID values. It shouldn’t be possible to duplicate the post ID, if the database had referential integrity.
Don’t tell me!
Ghacks wants the state to step in for STATE-MANDATED associations to save jobs!!!
Bring in the dictatorship!!!
And screw Rreedom of Association – too radical for Ghacks maybe
GateKeeper ?
That’s called “appointing” businesses to do the state’s dirty work!!!!!
But the article says itself that those appointed were not happy – implying they had not choice!!!!!!

As it stands, except for articles by Martin Brinkmann, Mike Turcotte, and Ashwin, they are low quality, unhelpful, and even vicious. It is better not to read those articles.

By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).

We all live in digital surveillance glass houses under scrutiny of evil people because of people like Musk. It’s only fair that he takes his turn.
“Operating systems will be required to let the user choose the browser, virtual assistant and search engine of their choice. Microsoft cannot force users to use Bing or Edge. Apple will have to open up its iOS operating system to allow third-party app stores, aka allow sideloading of apps. Google, on the other hand, will need to provide users with the ability to uninstall preloaded apps (bloatware) from Android devices. Online services will need to allow users to unsubscribe from their platform easily. Gatekeepers need to provide interoperability with third-parties that offer similar services.”
Wonderful ! Let’s hope they’ll comply with that law more than they are doing with the GDPR.
