Samsung Display has improved upon its QNED (quantum dot nanorod LED) display technology to a near production level. The company is expected to start investing in production equipment by 2021, and further commercialization soon after.

According to TheElec report, the South Korean tech giant has recently filed for over 94 patents. These featured major improvements in technology in patents filed in the second half of 2020 over those that were filed in the first half of this year. Furthermore, the backplane used on the Samsung QNED has a 7T2C TFT (thin film transistor) structure and an oscillator transistor to align the nanorod LED and repair transistor were also found placed alongside each other.

Notably, the circuit design of the QNED technology was similar to the Samsung TFT structure that is used on the company’s mobile OLED panels. An analysis from UBI Research also found that the addition of oscillator transistor as an interesting find within the recent patents, since these had not been used in display panels before. At the moment, the yield rate of the new QNED technology is the primary concern for Samsung.

Per pixel, about 10 to 20 nanorod LED have to be properly aligned otherwise it would lead to a short circuiting of the pixel. Hence, a repair transistor is also being included. Samsung Display has only spent 4 years to develop its QNED technology, but it seems that the company is already confident in its viability for production and would soon investment in production equipment for its factories by 2021.

It is a known fact that Samsung is the leading player in the foldable smartphone market. The South Korean tech giant is the only company to sell two different form factors of foldable phones globally. Now, a new design patent filed by Samsung Display, the sister company of Samsung Electronics from 2018 has emerged revealing a third possible form factor with a dual-fold outward folding screen from the house of the chaebol.

Like most patents, this one too was unearthed by LetsGoDigital. Samsung Display filed this design patent in September 2018 with the KIPO (Korean Intellectual Property Office). However, it was only published on October 6, 2020, more than two years from the day of its filing.

This patent visualizes an outward folding foldable smartphone with dual folding points. In other words, it is similar to the folding phone prototype showcased by Xiaomi in early 2019. However, the one by Samsung Display is much better with a kickstand and sturdy hinges for “Flex Mode” present in Galaxy Z Flip and Galaxy Z Fold2.

That said, we would like to remind you again that this patent is filed by Samsung Display and not Samsung Electronics, which manufactures phones. Thus, the design patent does not include cameras, ports, speakers, and even volume/power keys for that matter.

Therefore, Giuseppe Spinelli, the graphic designer at LetsGoDigital included some of the missing things in his 3D renders that are included in this article.

Having said that, this design may never get adopted. That’s because the design patent is by the display wing of Samsung and not electronics. Secondly, the patent is now. Hence, if Samsung Electronics has a plan to introduce a similar form factor, there will be certain design tweaks.
