Toshiba Corp announced three models of the Cell Regza LCD TVs and five models of the Regza LCD TVs that support 3D video July 28, 2010.
The company will start releasing the LCD TVs in August 2010 in Japan along with the "Regza Blu-ray" Blu-ray Disc (BD) recorders, which can record 3D video.
46-inch Cell Regza TV unveiled
The Cell Regza is an LCD TV equipped with the Cell Broadband Engine microprocessor (Cell), which was jointly developed by Toshiba, the Sony Group and IBM Corp. The X1, the first model of the Cell Regza, has a screen size of 55 inches. It was announced Oct 5, 2009, the day before the opening of Ceatec Japan 2009, and garnered significant attention.
The new models of the Cell Regza, which are the "X2" (55 inches) and two types of the "XE2" (55 and 46 inches), can display 3D video while having the same functions as the X1. They come with special glasses that are used for viewing 3D images. The expected retail prices of the X2 and the 55-inch and 46-inch types of the XE2 are Â¥1 million (approx US$11,432), Â¥700,000 and Â¥600,000, respectively.
The LCD panels of the new Cell Regza TVs have white LED backlights. The backlight of the X2 is located directly behind the panel (direct-lit type) while that of the XE2 is positioned at the upper and lower parts of the panel (edge-lit type).
The number of white LEDs used for the X2 is 3,072, which are divided into 512 areas (16 x 32). And light emission is individually controlled for each of the 512 areas. When the brightness of all the white LEDs in one of the areas is at the maximum, the peak brightness of a displayed 2D image is 1,000cd/m2 (contrast ratio: 9,000,000:1).
