JOLED to Begin Commercial Shipment of World’s First Printing OLED Panels on Dec. 5

Planning sequential product development of 21.6-inch 4K high-resolution OLED panels produced using the RGB printing method

JOLED Inc. (headquartered in Chiyoda-ku, Tokyo; President and Representative Director: Nobuhiro Higashiiriki) has commercialized the world’s first organic light-emitting diode (OLED) panel produced using the “RGB printing method”, and began product shipment on December 5, 2017.

The product is a 21.6-inch 4K high-resolution OLED panel produced using the printing method. Since its foundation in 2015, JOLED has been conducting research to develop OLED panels using the printing method and working to establish mass production technology. It started shipping samples of the developed product in April 2017. After achieving the necessary levels in product quality and productivity, JOLED has begun commercial shipment. The product has already been selected for use in medical monitors, and JOLED will gradually ship the product for use in a variety of applications.

President Nobuhiro Higashiiriki says, “We are extremely happy to finally be able to ship our company’s RGB printing OLED panels in our third year of operation. From here, we plan to accelerate product development and supply OLED panels that match customer needs. We also hope to inspire further innovation in the world’s OLED panel market through our company’s technologies and products.”

OLED panels are self-illuminating devices that deliver superb picture quality with high contrast, high color reproducibility, and a fast response rate. They also combine advantages such as an ultra-thin profile, light weight, and low power consumption. Due to these characteristics, OLED panels are expected to be used for next-generation displays that will create new applications in a wide range of fields, such as medical and gaming displays, as well as automobile applications, in the medium-sized display market.

JOLED developed its proprietary RGB printing method as a method of manufacturing OLED panels. It also commercialized equipment*1 and process technologies that can be put to use for applying materials uniformly to a large substrate. In addition, with its proprietary top emission structure that can extract high light efficiency, JOLED has developed panels with excellent color reproducibility and a wide viewing angle.

Toward the goal of achieving a world full of excitement and emotion due to advanced devices, JOLED will strive to become the leading company in the OLED panel field.

JOLED Inc. is headquartered in Tokyo and uses its Ishikawa, Kyoto, and Atsugi Technology Development Centers as bases to conduct research, development, manufacturing, and sales activities for OLED panels, their parts, materials, manufacturing equipment, and associated products.
JOLED was founded in January 2015, combining the OLED panel development divisions of Sony Corporation and Panasonic Corporation, with the goal of accelerating mass production development and commercialization of OLED panels.
In 2016, the company started up a development & prototype line (substrate size: G4.5), establishing a mass production technology and improving productivity. Later, in April 2017, JOLED shipped samples of the 21.6-inch 4K panel, its first product, and began product shipment on December 5.

About printing OLED panels
Characterized by their simple structure, ultra-thin profile, and light weight, OLED panels are gaining attention as next-generation displays that can deliver superb picture quality. The OLED panel market is projected to continue growing at an annual rate of 22%, reaching 40 billion dollars by 2021 *2.
The printing method, which is one of the methods for manufacturing OLED panels, is a technology in which OLED materials are applied to the substrate through a printing technique to form an electroluminescent (EL) layer. Due to the simplicity of the production process, it is expected that this technology will be easily adaptable to OLED production in various screen sizes. JOLED plans to popularize its printing OLED panels in the medium-sized OLED market in which the current mainstream chemical vapor deposition method is considered difficult to use.
