  • Panasonic Develops World's Largest 152-Inch Full HD 3D Plasma

    Panasonic annonced that it has developed the world’s largest 152-inch 4K x 2K (4,096 x 2,160 pixels) definition Full HD 3D plasma display. The display features a new plasma display panel (PDP) Panasonic developed with its new quadruple luminous efficiency technology.

    According to Panasonic, self-illuminating plasma panels offer "excellent" response to moving images with full motion picture resolution, making them suitable for rapid 3D image display.

    The company claims the new panel achieves a higher illuminating speed, about one fourth the speed of conventional Full HD panels.

    The panel also incorporates a crosstalk reduction technology, essential for producing clear 3D images. Compared to other display technologies that use line-at-a-time driving method, PDPs use frame-at-a-time driving method that gives PDP TVs an advantage in crosstalk reduction in principle.

    Panasonic has developed this technology to minimize double-image that occurs when left- and right-eye images are switched alternately. The development has resulted in the 3D compatible plasma display that can render clear and smooth high-quality pictures by accurately reproducing video sources.

    “The new 152-inch panel also uses a new technology that enables even and stable discharge,” as the company states.

    “Thanks to this discharge technology, the new panel can provide full HD images for left and right eyes formed with twice the volume of information as regular full HD images across the vast expanse of the screen equivalent to nine 50-inch panels with super high resolution (4,096 x 2,160) – four times the full HD (1,920 x 1,080) specification – while maintaining the brightness.”

    Because 3D plasma displays can reproduce highly realistic images, they are considered ideal not only for home theater use but also for a wide variety of uses such as business, medical, education and commercial applications.

  • Panasonic Develops 50-inch Full HD 3D PDP

    Aiming to bring Full HD 3D TVs to the market in 2010, Panasonic steps up its efforts in developing the related technology. The company has just developed a 50-inch Full HD 3D compatible plasma display panel (PDP) and high-precision active shutter glasses that enable the viewing of theater-quality, true-to-life 3D images in the living rooms.

    The new PDP and glasses evolved from Panasonic’s Full HD 3D Plasma Home Theater System that was developed in 2008 and comprised of a 103-inch PDP and a Blu-ray Disc player. The prototype PDP has a 50-inch screen, which is expected to become the most popular size for home theaters.

    This 50-inch PDP uses Panasonic’s newly-developed high-speed 3D drive technology that enables rapid illumination of pixels while maintaining brightness. The panel also incorporates a crosstalk reduction technology allowing for minimizing double-image (ghosting) that occurs when left- and right-eye images are alternately displayed.

    As PDPs are self-illuminating device with full motion-picture resolution, they offer fast response time and are suitable to display fast-moving images. The high-speed 3D drive technology involves the development of new panel materials and LSIs that accelerate the pixel illumination while maintaining brightness.

    Panasonic also developed the crosstalk reduction technology using phosphors with short luminescence decay time and illumination control technology to reduce double-images that occur when left- and right-eye image are alternated on the panel. This technology contributes to achieving high-quality clear pictures with high-contrast and accurate color reproduction. As the new technologies can also be applied to improve the quality of 2D images, they have expanded PDP’s potentials for further evolution.

    To reproduce 3D images, Panasonic uses the Full HD x 2 frame sequential method that displays time sequential images, alternately reproducing discrete 1920 x 1080 pixel images for the left and right eyes on the display frame by frame. The frame sequential method is widely used in showing Hollywood 3D movies in theaters.

    The active shutter glasses employ Panasonic’s technology that controls the timing of opening and closing the shutter in synchronization with the left- and right-eye images alternately shown on the PDP. According to the company, this technology enables significant reduction of crosstalk that degrades the image resolution in 3D display. The glasses are designed to fit for a wide range of users from children to the elderly.

    Panasonic has been working to develop its original Full HD 3D technology to create synergy between PDPs, which excel in moving picture resolution and color reproduction, and Blu-ray Disc players, which are able to faithfully reproduce high quality Hollywood 3D movies.

    The company continues to work on developing 3D products, targeting to launch the products in Japan, Europe, and the U.S. in 2010.

    Prototype Full HD 3D TV and glasses will be displayed at CEATEC JAPAN 2009 to be held from October 6 to 10 in Chiba City, east of Tokyo.
