OSAKA, Japan, Jan. 8, 2013

OSAKA, Japan, Jan.8, 2013 /PRNewswire/ --Panasonic Corporation has developed
a 56-inch organic light-emitting diode (OLED) panel with4k2k resolution
(3,840 x 2,160 resolution, 8.29 million pixels), the world's largest OLED
panel produced through the "RGB all-printing method."(1) Prototype panels
will be exhibited at the 2013 International CES in Las Vegas, Nevada, from
January 8 to 11, 2013.

In the printing method of production of OLED panels, 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 the technology will be easily adaptable to the
production of OLED panels in a variety of screen sizes. Through the printing
method, it is also possible to apply just the right amount of organic material
to where it is needed, reducing waste material and shortening production lead
time, making the printing method of production more economical.

In the production of the OLED panel, Panasonic is utilizing the RGB
all-printing method, which allows for the separate application of the red,
green and blue OLED materials by means of printing, and has developed the
equipment and process technologies to apply the materials uniformly to a large
substrate.

In addition, with Panasonic's proprietary top emission structure with a
transparent cathode, which can extract light more efficiently, it has been
possible to achieve the world's largest 56-inch RGB all-printing method-based
4k2k OLED panel with excellent color reproduction and a wide viewing angle.

As OLED panels are self-illuminating devices, they deliver superb picture
quality with high contrast, high color reproductivity and a fast response
rate. They also combine the advantages of plasma and liquid crystal display
(LCD) panels, such as an ultra-thin profile, light weight and low power
consumption. Due to these characteristics, OLED is considered as a promising
option for next-generation displays that will create new applications in a
broad range of fields, for use not just in the home, but in medical,
broadcasting and aircraft applications. With the advancement of display
technologies, which may enable sheet-type or flexible displays, OLED panels
will find more applications in a wider range of industries.

Panasonic has been carrying out its own research and development in OLED
technology. The company is exploring ways to capitalize on the
characteristics and potential of OLED devices to the fullest extent, taking
advantage of its know-how in manufacturing and achieving high picture quality
it has cultivated in its development of PDP and LCD flat-panels. Panasonic is
also collaborating with Sony Corporation to develop mass-production
printing-based technology for OLED panels.(2) The thin-film-transistor (TFT)
substrates used in the prototype panels were supplied by Sony as part of the
collaborative efforts.

Panasonic will continue to accelerate innovations in display device
technologies and further strengthen its R&D activities, with the aim to create
customer value.

[Main features of the new OLED technology]

1) The RGB all-printing method suitable for large panels

In the printing method, the same print head can be used regardless of the
panel size during the process of forming the EL layer, and the production
process is simple and does not require a vacuum environment or a high
temperature process, it is considered highly scalable and suitable for
producing large panels.

Panasonic has developed printing equipment and process technologies that
enables the separate application of the RGB OLED materials by color, while
applying the materials evenly on a large panel. As a result, the company has
succeeded in producing OLED panels as large as 56 inches, the world's largest
all RGB all-printing method-based panel, with 4k2k resolution.

2) The combination of the RGB all-printing method and the unique top emission
structure with a transparent cathode achieves excellent color reproduction and
a wide view angle

Through utilizing the RGB all printing method, in which red, green and blue
light-emitting materials are applied individually in each sub-pixel, and a
color filter, which tunes the color of the emissions, it has been possible to
achieve high color purity and superb color reproduction on the 56-inch OLED
panel. The OLED panel also has a wide viewing angle, thanks to Panasonic's
own top emission structure with a transparent cathode, which improves the
light extraction efficiency by extracting light in the upward direction
through a transparent cathode from the EL layer without multiple reflections.
