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.

On June 18, 2020, Jiangsu Lemeng Precision Science and Technology Co., Ltd. (江苏乐萌精密科技有限公司, hereinafter Jiangsu Lemeng) invested 200 million yuan to sign a project contract to confirm the OLED metal mask. It was held in the state-of-the-art new district of Changzhou, Changzhou, Jiangsu Province.

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.

China has entered the localization of PI. Although it has grown to the world’s highest level of LCD production, it is still only a few percent in the OLED panel market. In the OLED field, the Chinese government continues to invest heavily in panel makers, mainly BOE, to help China become the best production base. However, the supply chain of parts and materials that are essential for producing OLED is very poor.

The U.S. Patent Office has awarded patent number U.S. 10,593,886 to Molecular Glasses, Inc. for “OLED Devices with Improved Lifetime Using Non-Crystallizable Molecular Glass Mixture Hosts”

Japan Display (JDI) announced on the Jan. 31st that they have signed a final contract to receive investment of up to 108 billion yen (980 million dollar) from Ichigo Asset Management. Therefore, the company is expected to release its debts and invest in new fields such as fingerprint sensors. However, it has yet to be determined whether JDI will invest in OLED for Smartphones.

According to UBI Research’s 4th quarter OLED display market track, rigid OLED is still the main product in the OLED market for smartphones, with 79.2% of the total OLED market in 2019. As a result of counting and analyzing shipments up to the third quarter of 2019, rigid OLED accounted for 237 million units of the total shipment of 338 million units.

According to UBI Research’s 3rd quarter OLED display market track, the size of OLED for smartphones is gradually shifting from 5.5~5.99 inches to 6~6.49 inches.
Among the OLED shipments for smartphones of 430 million units in 2017, 5.5-5.99 inches accounted for 52.5%, but in the shipment performance until the third quarter of 2019, 5.5-5.99 inches decreased to 49.6% and 6-6.49 inches increased to 42.3%.

Samsung Display chose QD-OLED as the next generation premium TV. It will also have a big impact on the premium TV market, which is divided between white OLED technology and QLED technology.

Sony, which is driving the OLED TV market with LG Electronics, is exhibiting OLED TVs with new features at CES and IFA after the first display of OLED TVs.

This was the first time for JOLED to demonstrate its products and technologies at FINETECH Japan 2018.
JOLED, which received the inkjet OLED technology from Panasonic and is doing OLED panel business, has been selling medical monitors since early this year. Next year, Asus is also scheduled to sell inkjet OLED TVs made by JOLED.

Having a Gen5.5 7.5K line in Shenzhen, Royole is known as a head mount display (HMD) company rather than a display company. After completing installation of equipment in the second quarter of this year, Royole has been developing panels for the target of 7.8-inch tablet PC.

Japan, which used to be the strongest country in display industry in the past, gradually declined through the era of CRT, PDP and LCD, and has fallen to the third-largest producer in OLED industry after China.

According to the 3Q AMOLED Market Track issued by UBI Research, the second quarter OLED market was sluggish, affected by the lower utilization rate of Samsung Display. However, in the third quarter, the market rebounded rapidly, forming a market of US$ 8.3 billion.
