Panasonic has developed a 56 inch organic light-emitting diode (OLED) panel with 4k resolution (3,840 x 2,160) the world’s largest OLED panel produced through the “RGB all-printing method”. Prototype panels are currently being shown at CES 2013.
The RGB all-printing method allows for the separate application of the red, green and blue OLED materials by means of printing, and Panasonic has developed the equipment and process technologies to apply the materials uniformly to a large substrate. The specifications of the prototype panel currently on display are as follows: 55.6 inches diagonal, 4K resolution, 500cd/m2 peak luminance, 10-bit greyscale, 3 million to 1 contrast ration, NTSC (u’ v’): 100% color gamut, 8.9mm thick at its thinnest and a weight of 12.4kg.
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.
