PDP boasts 5,000,000:1 contrast ratio

Panasonic Corp. has developed new plasma display panels (PDP) that claim quadruple luminance efficiency, which will be incorporated in all 2010 models of VIERA plasma HDTVs.

The panels will also be featured in Panasonic's 152-inch Full HD 3D plasma display and VIERA Cast-enabled HDTVs supporting Skype video calls.

The new quadruple luminance efficiency panel evolved from Panasonic's NeoPDP panel developed in 2008 and NeoPDP panel developed in 2009 with twice and triple the brightness of its 2007 models, respectively. The new panels can produce the same screen brightness as 2007 panels using only a fraction of the electric power consumption of those panels three years ago.

The achievement of quadruple luminance efficiency panel involves major advances in many constituent elements of PDP: development of new phosphor materials, super high-speed drive technology and adaptive signal processing technology to reduce power consumption and improvements in all the facets of the panel-illuminating process that includes discharge, illumination and light extraction. These improvements have enabled the astounding progress in luminance efficiency resulting in a 42-inch Full-HD display that consumes a meagre 95W-less than a typical room lamp's 100W light bulb.

Furthermore, the new panel has enhanced a key advantage of PDP to the fullest extent, attaining a remarkable 5,000,000:1 contrast ratio. With superb colour rendition and subtle gradation of tones, the new panel faithfully reproduces details of high-definition sources from the pure white of virgin snow to the jet black of night.

As plasma display panels are self-illuminating devices, they offer other well-known advantages such as wide viewing angles and full resolution of moving pictures. Coupled with these inherent benefits of plasma technology, the new plasma panel has taken PDP's image rendering quality to an even higher level. The new panel delivers high-contrast, full-colour, higher brightness, crisp and clear spectacular images—even fast-moving sports scenes—regardless of the viewing angle.

The new display technology will not only enable further enhancement in image quality and energy-savings in 2D flat-panel TVs but also in the new Full HD 3D home theatre systems. And vivid visual communications via video conferencing will be truly realistic, with high-quality images on a large-screen display at a scale never imagined before. Panasonic will take TV in the living room to a whole new level of entertainment and communication.

Panasonic will further capitalise on the technology acquired through the development of the new super-efficient plasma panel. The energy-saving technology, for example, can be applied to products in other categories. Panasonic will continue to deliver environmentally-friendly products that meet the diverse needs of customers around the world.

In fact further improvements in luminance efficiency of plasma panels is expected in the years ahead, through continual advances in science and related refinements in design, materials and electrical components. And both consumers and industry are taking strong interest in this potential given the fundamental performance, durability and quality benefits of plasma.

In particular, further advances in 4Kx2K (4096x2160 pixels) super HD display technology will expand plasma's applications to such displays that can fulfil the most demanding needs of medical professionals, film studios and post-production houses, education, government and businesses of all kinds.

Panasonic will actively promote products using this new panel technology in both consumer and industrial markets, striving to deliver on its promise to create new and exciting TV experiences.
