OLED ink jet printing: introduction and market status - Page 6

In October 2020 TCL's CSoT demonstrated some new rollable OLED technologies, and today at CES the company published this nice video you see below that again demonstrates new rollable OLEDs:

TCL first shows a rollable smartphone, that uses a 7.8-inch AMOLED that rolls into a 6.7-inch one. The display features a bending radius of 3 mm and CSoT says it can withstand up to 100,000 sliding cycles.

TCL has been involved with OLED inkjet printing technologies for many years, and the company''s chairman and founder Li Dongsheng yesterday posted that the company will reveal its first printed OLED products next week. Li also uploaded the following video that showcases the company's inkjet printing technology:

This is somewhat surprising as it may be too early for TCL to actually launch inkjet printed OLEDs. TCL has been a long time believer in inkjet printing for OLED displays, and the company has established Juhua Printing in 2016 (together with Tianma and other collaborators) as an "open-innovation platform" to develop ink-jet printing of OLED panels. Last year TCL invested $187 million USD in Japan's inkjet printing developer and producer JOLED, and has also signed an agreement to jointly develop OLED TV printing technologies.

Notion Systems, MBraun and the Fraunhofer Institute for Applied Polymer Research (Fraunhofer IAP) are co-developing new inkjet production technologies, aimed for the display market - specifically for OLED, QD and microdisplays.

The three partners are combining their respective competencies to present themselves together as a partnership supplier off all-in-one solutions. The Fraunhofer IAP is developing custom-made processes for display manufacturing with tailor-made inks. To achieve an industrial-scale best-in-class process solution, the parties are looking into all major pre-and post-processing steps, the substrate and the production equipment such as the inkjet print head.

Japan-based inkjet printed OLED JOLED announced a partnership with Germany-based AERQ to integrate medium-sized OLED displays in aircraft cabins.

AERQ, interestingly, is a joint venture between LG Electronics and Lufthansa Technik, founded in 2019. AERQ aims to introduce innovative technologies to the aviation industry, and the company provides a digital ecosystem for aircraft cabins that consists of an open IT platform, inseat system, and Cabin Digital Signage. AERQ has already been showing large-area OLED display for aerospace applications (using panels by LG Display).

Najing Technology Corporation Ltd., the leading Chinese manufacturer of quantum dot materials uses the Notion n.jet display systems for QD displays and light emitting diodes development and pilot production.

The n.jet display series prints functional layers in various steps of display production and for various display technologies. This includes rigid, flexible, OLED, QLED and LCD displays. In addition to its unparalleled precision, the platform complies with highest demands on process environment and process stability.

According to reports from China, TCL says its CSOT OLED inkjet printing project is going well, and the company expects to start mass production at its 8.5-Gen Guangzhou T8 (owned by Huaxing Optoelectronics) production line in 2024.

Earlier this year the Guanghzhou development commission issued a report that says CSOT's investment in this R&D and production project will amount to 46 billion yuan ($6.8 billion USD), and the construction of the actual production line will be in 2021-2023.

Notion Systems and M.Braun announced a strategic partnership in OLED processing equipment. The two companies will combine their best-in-class OLED production technology to improve the production process offers and enhance market access in Asia.

M.Braun is a developer of glove boxes, inert gas purification and automation solutions while Notion Systems is a leading developer of industrial inkjet-printing systems for functional materials, and both companies already enjoy the growing demand of OLED manufacturing in Asia.

In December 2019 BOE unveiled a 55" 8K (160 PPI) OLED TV prototype produced by inkjet printing. The panel achieves a maximum brightness of 400 nits and a color gamut of 95% DCI-P3.

At SID Displayweek 2020, the company demonstrated this display and gave more details regarding its production process and display structure.

Samsung Display has developed a 18.2" 2560x1440 202 PPI inkjet-printed OLED display, that features the highest current efficiency of any inkjet-printed OLED, with the brightness at 350 cd/m² (full white).

Samsung Display says that the high brightness was achieved by tuning the top-emission device structure with high performance soluble materials. The high pixel resolution was achieved by modulating the jetting waveform for ejecting ink drops and improving the drop placement accuracy by selecting the right ink formulations in terms of viscosities and surface energies.
