Samsung’s QNED, will make a sensation in the TV and display markets?

/in , , /by

QNED (Quantum dot nanorod LED), which is known to be under development by Samsung, is becoming a hot issue in the display industry in 2020.

With the emergence of micro LEDs, followed by CRTs, PDPs, LCDs, and OLEDs as TV displays, the industry is interested in whether QNED could be another new technology.

Samsung Display is known to stop the LCD business and invest 13.1 trillion won as an alternative to do the QD-OLED business. In this situation, attention is being focused because the development of QNED can act as another variable in the future of Samsung Display’s large display business.

QNED uses oxide TFT and QD (quantum dot) -CF (color filter) technologies used in QD-OLED manufacturing. On the other hand, the pixel material that emits light is characterized by being changed to a nano-sized bar-type LED (nanorod LED), unlike OLED emitting materials. The pixel manufacturing technology, which is the core technology of QNED manufacturing, is a method of spraying nanorod LEDs dispersed in a solution into a pixel area by an ink jet method and arranging them in a self-align method by an electric signal.

UBI Research published a report that analyzed the structure and manufacturing technology of QNED based on the patented technology filed by Samsung Display. This report is structured to quantitatively analyze QNED-related patents filed by Samsung Display, so that QNED’s technology completeness and mass productivity can be known.

UBI Research (www.ubiresearch.com) published “QNED Structure and Manufacturing Technology Analysis Report”, which analyzed 41 cases of Samsung Display’s QNED (quantum dot nanorod LED) published patents.

The contents described in this report were selected from the 41 patents published, which are considered to be used for QNED manufacturing, and are constructed by qualitative analysis.

As a result of analyzing the published patent, the QNED structure was formed of TFT, pixel, and QD (quantum dot) -CF (color filter). In the published patent, all TFT structures are depicted as 2Tr (transistor), but it is estimated that a 3Tr1C structure will be used because at least three TFTs for current driving are required. The pixels consisted of nanorod LEDs, electrodes, and optical structures to increase light efficiency.

Until now, the electrode structure of the pixel was known to be rectangular, but as a result of analyzing published patents, the electrode structure is estimated to be circular. In a specific patent, when the asymmetric waveform was applied to the circular electrode, the alignment direction and alignment characteristics of the nanorod LED were improved. It is judged that the nanorod LED alignment electrode and the drive use the same electrode.

The nanorod LED used for QNED manufacturing is made of GaN and emits blue light, and the size is <1um x 10um. In order to increase the alignment effect of the nanorod LEDs and reduce process defects, the nanorod LED surface appears to be treated with an insulating film and an orientation radical.

What is the difference between the touch types of each model of iPhone 12?

All of Apple’s iPhone 12 models, OLED panels will be used and consisted of four models. There are three sizes, 5.4 inches, 6.1 inches, and 6.7 inches, respectively, and 6.1 inches are divided into two models.

Samsung Display and LG Display have begun preparing to mass-produce, with recent orders from Apple. Samsung Display plans to supply OLED panels of all sizes, LG Display plans to supply 6.1-inch OLED panels, and there are differences in touch type by size.

First, on-cell touch which a touch electrode is formed on a thin film encapsulation (TFE) is applied to 5.4 inch and 6.7 inch models. Each panel maker is called Y-OCTA (YOUM on-cell touch AMOLED), ToE (touch on encapsulation), FMLOC (flexible multi-layer on-cell touch), and unlike add-on touch, a touch electrode is formed directly on the upper layer without base films. Due to this, the on-cell touch has a higher process difficulty than the add-on touch, but it is advantageous to fabricate a thin OLED panel thickness, and the process cost is also reduced.

Add-on method is applied to 6.1 inches. A touch electrode is formed on the base film, and is attached on the TFE by adhesive. It has the advantage that the process is simpler than on-cell touch.

Recently, rumors that BOE is supplying 5.4 inch and 6.1 inch OLED panels to Apple have turned around, but 5.4 inch is on-cell touch type and it is still difficult to supply for iPhone 12 due to technical difficulty. BOE is developing a 6.1-inch OLED panel and has not received calls yet.

Apple’s new iPhone 12 will be consisted of 4 models, and all 4 models are expected to adopt OLED. The general lineup of the iPhone 12 is the 5.4 inch iPhone 12 and the 6.1 inch iPhone 12 Max, and the pro lineup is the 6.1 inch iPhone Pro and the 6.7 inch iPhone Pro Max.

Recently, rumors are floating that BOE will supply OLED of 5.4 inch and 6.1 inch general models, and Samsung Display will supply OLED of 6.1 inch and 6.7 inch pro models. Due to the news that Chinese OLED panel manufacturer BOE is supplying OLEDs to Apple, the interest of OLED-related companies such as light-emitting material companies and component companies is growing day by day.

According to UBI Research, BOE is developing 5.4 inch and 6.1 inch OLEDs, but has not received any calls from Apple. In the current situation, Samsung Display plans to supply 5.4 inch, 6.1 inch, and 6.7 inch OLEDs, and LG Display and BOE are developing 6.1 inch OLEDs.

The BOE hasn’t gotten a clear call yet, but there’s plenty of time left for the mass production of the iPhone 12, so there’s plenty of room for the BOE to get a call from Apple. While the production of the iPhone 12 is likely to be delayed by about a month due to the corona incident, it usually takes 4 ~ 5 months from the OLED panel test to the mass production of the set, so there is enough time.

78.6 tons of OLED emitting material demand increased by 5.6% in 2020

/in , , /by

According to the 2020 OLED emitting material report published by UBI Research, the demand for emitting materials in 2020 is 78.6 tons, which is 4.2 tons higher than last year’s 74.4 tons. The material used for OLEDs for smartphones and mobile devices is 62.9 tons, and the OLED emitting material for TVs is expected to be 15.7 tons.

In 2019, the total emitting material market was totaled at $ 1.28 billion, and 43% of the total amount was purchased from Samsung Display. It was found that the amount purchased by LG Display was 19.4% and the BOE was 11.6%. LG Display’s purchase of emitting materials accounted for 60.8% of TV use. The order of purchase of emitting materials for mobile devices is in order of Samsung Display, BOE, and LG Display. This is because BOE has a large amount of OLED production for mobiles after Samsung Display.

The OLED panel for TV only produces LG Display, but Samsung Display is pursuing QD-OLED commercialization using blue light emitting material and QD. In addition, although BOE is a white OLED structure similar to LG Display, it is developing a top-emission structure that transmits light in the opposite direction of TFT, and it is expected that three companies will produce OLED panels for TV within a few years, and the emitting material market is expected to increase as well.

 

The market for emitting materials in 2020 is expected to increase by 7% from 2019 to $ 1.37 billion. Among the emitting materials, green and red hosts are expected to be $ 19.2 billion and $ 19 billion, respectively, and green dopants and P + are expected to be $ 1.37 billion and $ 1.35 billion, respectively.

2020 OLED market change by coronavirus

According to UBI Research’s report on changes in the OLED market caused by coronavirus, the forecast for the 2020 OLED modification market is $ 36.7 billion in sales and 612 million units. This is a decrease of 4.8% and 7.6%, respectively, from the expected sales of $ 38.5 billion and shipments of 6.6 million units at the beginning of the year.

As a result of UBI Research’s analysis of the effect of coronavirus on the OLED market for two months, the global smartphone market is expected to drop by 20% and the TV market is expected to decrease by 15%. However, the impact on the overall OLED industry was judged to be only 5-8%. OLED panels for smartphones, TVs and watches are expected to decrease, but the market for OLEDs for monitors is expected to increase.

The expected OLED shipment for smartphones was 527 million units at the beginning of the year, but the forecast for correction is 486 million units, a decrease of only 7.8%. Although the market for Galaxy and iPhone is analyzed to be higher than the average decrease rate, Chinese smartphone makers are expected to reduce LCD smartphones and increase production of OLED smartphones significantly.

Chinese smartphone makers’ use of OLED seems to follow Apple’s business direction. Flagship models of Chinese smartphone makers have used Pro and Pro Plus. Pro is the model grade name used by Apple and Plus is the model grade name used by Samsung. However, flagship models of Chinese smartphone makers that are launching this year are using both Pro and Pro Max as well as Apple. All of these models, like Apple, plan to use flexible OLEDs.

The OLED TV market was found to be greatly affected by coronavirus. Estimated shipments at the beginning of the year were 4.9 million units, but the forecast for correction was 3.6 million units, down by 1.3 million units. A 26.5% reduction is expected. This is 300,000 units more than 2019 shipments. This is because the production schedule of the Guangzhou factory has been postponed since the third quarter due to the coronavirus, and TV sales are plunging due to the spread of coronavirus in Japan and Europe, the main markets for OLED TV. In fact, Japan’s TV performance in the second quarter was below 50% in 2019.

However, the demand for the OLED panel business for monitors that Samsung Display has been promoting since the second half of last year is expected to increase due to the game industry, telecommuting, telemedicine, and remote classes due to the aftermath of the coronavirus.
