Panasonic Develops 50-inch Full HD 3D PDP
Panasonic has 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. Aiming to bring Full HD 3D TVs to the market in 2010, the company steps up its efforts in developing the related technology. The new PDP and glasses evolved from Panasonic's world-first 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.
To describe further about the technologies involved with the new panel, Panasonic newly developed the high-speed 3D drive and crosstalk reduction technologies to improve plasma's unique properties to deliver crisp and clear Full HD 3D images. 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 newly-developed 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 new panel elevates home entertainment to a whole new level with theater-quality 3D images.
The high-precision active shutter glasses employ Panasonic's technology that precisely controls the timing of opening and closing the shutter in synchronization with the left- and right-eye images alternately shown on the PDP. 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.
