Mitsubishi Electric Corp developed an LCD TV whose display is separated from the tuner and as thin as 40mm.

The TV has a resolution of 1920 x 1080p (full HD). The company did not unveil the specifications such as the display size, the surface luminance and the contrast ratio. The company plans to roll out the product based on this prototype in fall 2008.

The display size of the product will be 40 inches or larger, the company said. "Ultrathin" LCD TVs based on similar techniques have already been commercialized by Hitachi Ltd and Sharp Corp.

Mitsubishi's new TV uses uncompressed wireless communications to transmit video signals between the display and the tuner. Built-in wireless transmission units are provided in both the display and the tuner.

When asked about the communication standard and the frequency bandwidth used, Mitsubishi declined to answer. The communication distance is up to 30m, which is sufficient for indoor use, the company said.

Wireless High-Definition Interface (WHDI) and Wireless HD are known communication standards that can transmit uncompressed full HD image signals. The former is being formulated by Amimon Ltd of Israel, while the latter is being standardized by SiBEAM Inc, Sony Corp, Matsushita Electric Industrial Co Ltd, Toshiba Corp and Samsung Electronics Co Ltd of Korea.

To reduce the display thickness to 40mm, the company reportedly nearly halved the thickness of the LCD panel module, power circuit and inverter, etc, when compared with those used in the company's existing products. The panel module was jointly developed with a LCD panel manufacturer, according to Mitsubishi.

Seven new models also released

Prior to the market debut of the 40mm-thick LCD TV, Mitsubishi will also release seven new models to be added to the REAL LCD TV series. They are slated for launch in order from Sept 1, 2008. The company aims to "sell about 300,000 units a year" in a total of seven models.

The MZW series, which is the higher-end line, comes in 46- and 40-inch models. They have a design well-suited for the living room, according to Mitsubishi. When used with the "wall-side stand," the distance between the wall and the front surface of the TV is only 92mm.
