JOLED Builds Mass-Production Lines in Chiba Site for Post-Process of Printed OLED Displays

Utilizing JPY25.5 billion of funds raised by a capital increase through third-party allocation of shares

JOLED Inc. (headquartered in Chiyoda-ku, Tokyo; Representative Director and President: Tadashi Ishibashi; hereafter “JOLED”), which develops, manufactures, and sells organic light-emitting diode (OLED) displays, has been developing the world’s first printed OLED display mass-production lines, and started building production lines for the post-process at the recently established JOLED Chiba Site. The facility development is carried out utilizing some of the funds amounting to JPY25.5 billion in total, raised by a capital increase through the third-party allocation of shares, to INCJ, Ltd. (headquartered in Chiyoda-ku, Tokyo; President and COO: Mikihide Katsumata), Sony Corporation (headquartered in Minato-ku, Tokyo; President and CEO: Kenichiro Yoshida) and Nissha Co., Ltd. (headquartered in Nakagyo-ku, Kyoto-shi; President and CEO: Junya Suzuki; hereafter “Nissha”).

OLED displays by JOLED will be produced through the pre-process from the array process to the printed OLED process conducted at JOLED Nomi Site and the module process that constitutes the post-process, conducted at Chiba Site. After passing the final inspection, the completed display products are being shipped to customers from Chiba. The production capacity at Chiba Site will be approximately 220,000 units of OLED displays per month. Chiba Site is scheduled to start operations in 2020, simultaneously with Nomi Site.

The entire production process of JOLED’s OLED display production lines will consist of the pre-process at Nomi Site and the post-process at Chiba Site. This process will become operation in 2020, with JOLED set to produce medium-sized (10- to 32-inch) printed OLED displays for use in areas such as automotive displays and high-end monitors.
Nissha, who recently became a joint shareholder, produces film-based touch sensors as one of its major products. JOLED will work together with Nissha in the area of touch sensors for various OLED displays in the future.

With the proprietary RGB printing technology for producing OLED displays, which enables efficient production and represents a major innovation within the OLED industry, JOLED will complete the entire process of mass-production lines as scheduled to offer medium-sized, high-definition OLED displays demanded by the market. JOLED will continue to take on challenges with the aim of leading the OLED industry, fulfilling its mission to realize a world full of excitement and emotion, drawing on leading-edge devices.

JOLED Inc. is headquartered in Tokyo and uses its Ishikawa, Kyoto, and Kanagawa Technology Development Centers as bases to conduct research, development, manufacturing, and sales activities for OLED displays, their parts, materials, manufacturing equipment, and associated products. JOLED was founded in January 2015, combining the OLED display development divisions of Sony Corporation and Panasonic Corporation, with the goal of accelerating mass production development and commercialization of OLED displays.

JOLED launched a pilot line in 2016 and established the mass-production technology for printed OLED displays. Shipment of products started in 2017. Currently, construction of the world’s first mass-production lines for printed OLED displays is underway at Nomi Site, with a target to start mass production in 2020.

About printed OLED displays

OLEDs are self-illuminating devices that deliver superb picture quality with high contrast, high color reproducibility, and fast response rate. They also combine advantages such as an ultra-thin profile, light weight, and low power consumption. Due to these characteristics, OLEDs are gaining attention as a next-generation display that will create new applications in a wide range of fields.
The printing method, which is one of the production methods for OLED displays, applies and forms OLED materials by printing. With its simple production processes and the flexibility to cope with diverse screen sizes, the technology is expected to represent a major innovation in OLED display production.

In the OLED display industry of today, the vapor-deposition method has been the mainstream method employed for production. However, the vapor-deposition method is said to be difficult to apply when producing medium-sized OLED displays. Thus, JOLED is producing medium-sized OLED displays using the printing method instead, with the aim of giving rise to the medium-sized OLED display market. JOLED is also determined to promote its technology licensing activities for offering production technologies fit for large-sized TVs in efforts to have JOLED’s printing production technology make inroads into the markets of large-sized products.
