推出？
只是概念产品而已
大大，是出了，sony的也来了

The biggest announcement from Sony’s IFA press conference, if you’re going purely by the size of the device, was the unveiling of its KD-84X9005 BRAVIA LCD TV. Packing an 84-inch LCD panel with 3,840 x 2,160 pixels (that’s a total of 8.29 megapixels), the KD-84X9005 is Sony’s first 4K television and outdoes Sharp’s AQUOS LC-90LE745U in resolution, although not in size. In another first, the edge-lit LED unit also features passive 3D instead of the active 3D seen in the company’s previous 3D models.
With four times the resolution of Full HD (1080 x 1920), the KD-84X9005 boasts a pixel density of 52 ppi (pixels per inch), as well as a 60-degree viewing angle. The unit also incorporates an optimized version of Sony’s “X-Reality PRO” picture engine that sees the addition of a database for 4K LCD TVs and a 4K upscaling feature to up the resolution from sources ranging from low-resolution internet videos to HD digital broadcasts and Blu-ray footage – a necessary inclusion with native 4K content virtually nonexistent. The “4K X-Reality PRO” engine also upscales Full HD resolution Blu-ray 3D images to separate 3,840 x 1,080 resolution images for both the left and right eye using a polarizing sheet on the TV’s screen. The switch to passive 3D means the glasses are lighter, cheaper and require no batteries.
