Invar, which is used for metal masks, is an iron-nickel alloy material necessary for manufacturing FMM for depositing RGB in OLED manufacturing.

Phillmaterials is using Invar as an ultra-high resolution display material because it has a low thermal expansion rate and thin thickness using the electroplating method.

Pixel Shadow can be improved compared to the compressed FMM. 6G half-sized OLED mobile masks and IT masks were also displayed.

Unlike the existing FMM method, Olum Materials used a method of attaching individual cells to a frame.

It is effective in preventing sagging in a large area, and if a mask is defective, it has the advantage of not replacing the entire mask.

Olum Materials exhibited a mask of 6G half size, they are developing it in the lead of localization.

/in /by

At the ‘Display Business Forum 2022’ held at COEX, Seoul from August 10 to 12, 2022, Sumitomo Chemical unveiled the performance of inkjet materials developed until recently.

Inkjet printing technology is attracting attention as a technology that can reduce the process time and increase material usage of 3-stack OLED or 4-stack OLED, which are mainly used for medium and large-sized devices. JOLED is mass-producing panels for monitors, and TCL CSOT also are considering investing.

Sumitomo Chemical first disclosed the RGB performance of the top-emitting OLED and the bottom-emitting OLED produced by spin coating. Although there was no significant difference in the OLED of the bottom emission type from the previous year, it was confirmed that the performance of the material was improved in the OLED of the top emission type, and in particular, both the efficiency and performance of the blue material were improved.

At the ‘Display BUSINESS Forum 2022’ held on the 11th, Kang Won-seok, managing director of LG Display, said that the use of transparent OLEDs is increasing due to improved transmittance and reduced weight.

Director Kang mentioned that LG Display has been developing transparent OLED since 2014, and announced that he would increase the value of transparent OLED in line with internal activities that have been increasing since COVID-19.

LG Display Transparent OLED Roadmap

Currently, LG Display is mass-producing transparent OLED on a limited basis in its E3 line. Currently, only 55-inch transparent OLEDs are being mass-produced, but from the second half of this year, they plan to expand the lineup to 77 inches.

LG Display’s transparent OLED is mainly used for museums and signage in China. As demand is expected to increase in the future, LG Display is expected to respond to the market by lowering panel prices and introducing production lines other than E3.

At the ‘K-display 2022 Business Forum’ held at COEX from August 11th to 12th, CEO Il-jae Lee of Coses GT presented ‘Cover Window for Foldable and UTG Manufacturing Method’.

Regarding the foldable phone market, CEO Lee said, “According to UBI Research data, the size of the foldable market is expected to grow to 1 trillion won by 2025. Recently, not only Korea, but also China and the United States are actively engaged in foldable-related businesses. We are concentrating on securing competitiveness in UTG and hinge technology to catch up with Samsung Electronics such as Apple in the US and Huawei, Oppo and Honor in China.”

Next, explaining the characteristics of UTG products, “OCA and PET films are attached on the UTG products that are actually used and hard coating and anti-finger coating are made. If you do a pen-drop test on the 30um thick UTG of CosesGT, the panel breaks at 2.5cm. If PET film is applied over UTG, it can withstand up to 25cm in the pen-drop test, but the unique properties of UTG are greatly damaged. We are thinking about how to proceed with UTG alone without any special process on top of UTG.”

Regarding product mass production, “Actually, the Galaxy flip or fold-sized panel developed by CosesGT can be mass-produced with a thickness of 50 to 70um. Samples can be made with the same thickness as flip and fold for a 17-inch or larger medium-large panel such as a laptop, but considering mass production, it can be produced with a thickness of 70-100um.”

According to the announcement, the actual folding radius of the panel developed by CosesGT achieved a radius of 0.9R at 6.8 inches, 1.2R at 8.2 inches, and 4R at 17 inches. The folding test passed 170,000 times for 96 hours at 60°C and 170,000 times for 96 hours at -20°C, a total of 340,000 folding tests.

Finally, when asked about the most difficult aspect of UTG development by Chinese UTG processing companies, he said, “Recently, Chinese panel makers’ UTG demand is increasing, but Chinese processing makers have not yet entered the UTG business. The hinge technology of Chinese processors is also a problem, but the development of foldable phones is still being delayed because the proportion of foldable phones in the smartphone market is still small. Also, UTG processing companies in China seem to think that early UTG and glass are the same material and can be easily developed.”
