Panasonic unveils a 56-inch OLED panel produced with RGB all-printing method

January 14, 2013 // By Julien Happich
Featuring 8.29 million pixels in a 3840x2160 resolution format, the panel is believed to be the world's largest OLED panel produced through the "RGB all-printing method" whereby materials are applied to the substrate through a printing technique to form an electroluminescent 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.

The RGB all-printing method allows for the separate application of the red, green and blue OLED materials. Panasonic has developed the equipment and process technologies to apply the materials uniformly to a large substrate.

The company's proprietary top emission structure with a transparent cathode, can extract light more efficiently, it supports 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 reproduction and a fast response rate. They also combine the advantages of plasma and liquid crystal display panels, such as an ultra-thin profile, light weight and low power consumption. Panasonic is also collaborating with Sony Corporation to develop mass-production printing-based technology for OLED panels. The thin-film-transistor (TFT) substrates used in the prototype panels were supplied by Sony as part of the collaborative efforts.
