QNED, how far has it come?
As a result of analyzing a total of 160 QNED-related patents, a patent related to 3T1C and a patent dealing with the driving method in detail were found. In addition, a patent that describes various elements constituting the QDCF layer has been disclosed.
An analysis of 160 patents revealed the structure of QNED more clearly. It seems that the manufacturing technology and driving method, including the nano-rod LED alignment technology, which is the core technology of QNED manufacturing, are highly complete.
OLED Emitting Materials Market Forecast
In the first quarter of 2021, the total market for emitting materials in 2021 was $1.52 billion, and it is expected to form $1.96 billion by 2025.
The reason that the light emitting material market is not expected to exceed $2 billion is that due to the Covid-19 crisis and Huawei sanctions, smartphone panel shipments were expected to be in the mid-500 million units, and TV panel shipments were also projected to be less than 7 million units by 2025.
QNED Technology Maturity Analysis Report
The reality of QNED (quantum dot nano-rod LED) that Samsung Display is preparing as a next-generation display has become clear.
As a result of analyzing 160 patents applied by Samsung Display, it was confirmed that the structure constituting the QNED has already been completed, and that the only remaining task is to keep the number of nano-rod LEDs arranged in the light-emitting pixel constant.
The number of aligned nano-rod LEDs per pixel, which determines the yield and image quality of QNED, is determined by the distribution of LEDs in the ink, the number of LEDs injected into the pixel, and the alignment ratio of the injected LEDs.
OLED Related Presentation Analysis in SID 2021
We analyzed all 283 Oral Presentations at SID held in virtual from 2021.5.17 to 21.
When Oral Presentation was categorized by theme, OLED had the highest number of 50. The number of OLEDs announced in recent years was the highest, especially in 2020, which was 71. Although it decreased in 2021, it still has the most announcements
Analysis of China’s OLED Industry Trend
The Chinese OLED market has slowed growth due to COVID-19, but is showing a recovery trend as panel makers resumed OLED investment and line expansion from the second half of last year. The ‘China OLED Industry Trend Analysis Report’ investigated the business status of Chinese panel makers and analyzed the status of component materials and light emitting materials and the supply chain.
OLED Performance Analysis in 1Q 2021 and Forecast for TV
In the COVID-19 situation, the rapidly growing OLED TVs recorded 4.4 million units in 2020, and the growth of OLED TVs is also increasing rapidly in 2021.
LG Display, which exclusively produces OLEDs for TVs, has started panel production at its Guangzhou plant since the third quarter of 2020. And for the time in 6 months, LGD achieved a speed battle that raised the yield to 90%. As a result, LG Display can produce 9.2 million panels annually.
SID 2021, Mini LED & Micro LED Display Exhibition Trend Analysis
At the Technical Session of the SID Symposium, there were 290 oral presentations and 118 poster presentations.
32 micro LEDs were announced, 28 at the Technical Session and 4 at the poster.
OLED-related exhibition status by panel maker at SID2021
AUO introduced a 32” inkjet printing AMOLED display, a 5.6” rollable dual-side AMOLED display, and a 1.28” low power AMOLED display at SID 2021.
The resolution of the 32” inkjet printing AMOLED display was 4K and the refresh rate was 144Hz.
China’s Counterattack, Rollable Phone
Chinese companies are showing offensiveness in the heterozygous form factor market, which is represented by foldable and roller blobs. In particular, the rollable phone offensive is increasing.
OPPO and TCL, which are competing for the first and second place in the Chinese smartphone market, actively released prototypes and concept videos of rollable phones.
