As forecasted, the material purchase ratio by country in 2028 will be 56% in Korea and 44% in China. However, Chinese panel companies are mainly mass producing panels for Chinese domestic use and white boxes, so even if panel shipments increase in the future, low-priced materials will be used. So, there is a possibility that the expansion of China’s emitting material market will be reduced further than currently expected.

Lastly, UBI Research predicted that Samsung Display’s purchase of emitting materials in 2028 will reach $810 million, LG Display’s will reach $550 million, and BOE will reach $440 million.

Merck Has Completed the Development of Organic Material Samples for Low Dielectric Constant TFE Below 2.5 [2022 Second Half OLED Seminar]

Touch of flexible OLED for smartphones is divided into add-on and on-cell. Add-on is a method in which a touch electrode is formed on the top of the film and the touch film is adhered to the top of the encapsulation layer through OCA.

On-cell is a method in which touch electrodes are created directly on the encapsulation layer, and is a mainstream technology applied to Samsung Electronics’ “Galaxy” series and Apple’s “iPhone” series.

The on-cell method reduces material costs because it creates electrodes directly without using films and OCA, while the absence of films and OCA shortens the distance between touch electrodes and TFT, increasing signal-to-noise (SNR).

Material Science Co., Ltd. develops high-purity blue light-emitting material with a half width of 11 nm

In OLEDs which are currently leading the display industry for mobile devices and TVs, blue material is still using fluorescent material unlike red and green.

Currently, a lot of light emitting material companies are trying to improve the efficiency, lifespan, and color purity of blue light emitting materials, also next-generation materials such as phosphorescence, TADF, and hyper-fluorescence as well as actively developing luminous efficiency by controlling emission wavelengths.

Material Science (hereinafter referred to as MS), a Korean company that has been developing blue light emitting materials since 2015, has recently focused on realizing high color purity and successfully developed high color purity blue light emitting materials with a light emission wavelength of 460 nm and a half width of 11 nm. Considering that the emission wavelength of the currently commercially available blue material is about 20 nm, the blue material of MS is expected to receive great attention.

The full width at half maximum (FWHM) is an expression of the extent of function given by the difference between the two extreme values of the independent variable at which the dependent variable is equal to half of its maximum value.

And the narrower the half width, the higher the purity.

A typical example is Samsung Electronics’ QLED TV, which has significantly improved color reproduction by applying a QD sheet to the LCD back light.

The blue light emitting material developed by MS is expected to be applicable not only to fluorescent materials but also to hyper-fluorescence, which is attracting attention as a next-generation blue material according to emission wavelength control.

Deuterium substitution blue, will be next generation blue materials?

Fluorescent blue emitting material is the only fluorescent material used in small and medium-sized OLEDs and large-area OLEDs.

Development of next generation emitting materials such as TADF and hyper-fluorescence is also in progress, but deuterium substitution technology has got attention since it is adopted to Samsung Galaxy S20.

Deuterium substitution technology is to replace hydrogen with deuterium in a compound combined with existing hydrogen, and each company has a difference in substituting the compound before or after synthesis or substituting the whole. Representative development companies for deuterium substitution include Idemitsu Kosan, DuPont, SFC, and JNC.

As related patents, compounds substituted with deuterium with an atomic mass of deuterium that is twice as high as hydrogen have lower zero-energy and lower vibrational energy than those combined with hydrogen, resulting in lower ground-state energy and weaker intermolecular interactions, resulting in a thin film in an amorphous state. It is effective in improving the life of OLED.

It is expected that the OLED device to which the deuterium-substituted compound is applied can improve the lifetime by more than 20% compared to the previous one.

JOLED is the only company producing OLED panels manufactured by inkjet technology. JOLED is also promoting the license business by providing this technology to Chinese, Japanese and Taiwanese panel makers.

[ICEL 2018] TADF attracts attention as next generation emitting material

In addition to monitors and virtual reality devices, OLED is gradually expanding its domain beyond smartphones and TVs, inclusive of the application of side-mirror OLED in automobiles. As new OLED applications are increased in various environments, it is essential to develop technologies to satisfy users.

In ICEL 2018, which is being held at Jeju International Convention Center from October 15th, many presenters and attendants emphasized that material development is essential to improve the performance of OLED as the OLED market grows more. As an alternative material, TADF (Thermally Activated Delayed Fluorescence) is mentioned.

First, Hwang Seok-Hwan, chief researcher in Samsung Display said that TADF is to be a good resolution as one of emitting materials for new deposition process, referring to the continued growth of OLED panel and material market.

Hwang said that the efficiency of fluorescent Blue is almost saturated, so 100% luminance efficiency can be obtained theoretically by applying TADF with the advantages of not using expensive rare earth metals. He added that improvement of material stability, improvement of color purity by using boron material, development of host having high triplet energy need to be superseded.

Also, CYNORA, a leading TADF developing company, disclosed the performance of dark blue TADF developed so far.

CYNORA said that the luminance efficiency and color purity of dark blue TADF reached the level that the related companies required, and that its current goal is to develop the technology to improve lifetime. In addition, based on this know-how, the company will quickly develop green and red TADF, and now green TADF has been delivered to several customers as a sample.

Merck confirmed that TADF is the most powerful luminescent material to replace fluorescent Blue at its presentation together with a poster about TADF.

OLED companies and research institutes are focusing attention on whether blue TADF can quickly enter OLED market and upgrade OLED performance further.

[ICEL 2018] What are the future challenges for LG Display to improve OLED TV performance?

At ICEL 2018, held at Jeju International Convention Center from Oct. 15, Soo-Young Yoon, Vice President and Head of LG Display Laboratory, presented the challenges for the OLED TV performance improvement and price reduction

Yoon said “In 2018, the future prospects of OLED TVs have changed more positively compared to that in 2016. In 2013, only LG Electronics was an OLED TV set maker. The number of OLED TV set makers has steadily increased; ten in 2016, and fifteen in 2018. Many TV set makers are choosing OLED. ”

He added that although OLED TV is on the track of success with lots of improvement, it has to be further developed. The challenge is the improvement for high brightness, color reproduction rate and with the development of 8K resolution. Also he mentioned that the price reduction is to be necessary.

Yoon explained that the development of components such as driver IC and controller is an important task to develop 8K OLED TV. In order to improve the brightness, color reproducibility, and lifespan, TADF and phosphorescent Blue are to be good alternatives for improving the RGB emitting materials. The enhancement of out-coupling is also important.

In addition, he referred to the solution processed OLED as a technology, to compete against LCD TV price, with the necessity of developing inkjet equipment, process, and soluble materials. For this, it is required to develop the ink jet equipment and shorten the process time for mass production, but the performance and reliability of the soluble materials will be more important.
Finally, he commented that the company will focus on 8K OLED TV and rollable OLED TV with the improvement of brightness until 2020. After 2022, the company will develop the OLED TV which has an enhanced brightness of 300 nits or more, a color gamut that satisfies BT.2020, and a lifespan of more than 30,000 hours.

[IMID 2018] LG Display, showcased 2-stack RGB OLED for automobile OLED with improved life span.

At IMID 2018 held in BEXCO, Busan on August 29, Kim Kwan-Soo, research fellow of LG Display presented about a new OLED technology for automotive displays.

Kim said that RGB OLEDs applied to mobile devices and WRGB OLEDs applied to TVs do not satisfy customers’ needs in terms of life span. To solve this issue, he introduced 2 stack RGB OLED in which RGB OLED has the same tandem structure as WRGB.

Because 2 stack RGB OLED can be thick due to adding a layer of CCL (charge generation layer) to the multi-layer structure, HTL is made thinner than before and the charge balance of the emitting layer is optimized.

As a result, the 2-stack RGB OLED shows 1.5 ~ 2 times higher emitting efficiency than the 1-stack RGB OLED. Its lifetime is increased by 4 times on T80 basis.

However, the 2-stack structure has a disadvantage in that it has higher power consumption than the general structure. Thus, it is necessary to make efforts to solve this disadvantage.
