Sony unveiled the Bravia VE5 series at the 2009 CES. The new series offer a zero-watt standby power switch, along with motion and light sensors that minimize energy, the company said.

The 52-inch KDL-52VE5, the 46-inch KDL-46VE5 and the 40-inch KDL-40VE5 models are also the first to incorporate Sony's micro-tubular hot cathode fluorescent lamp (HCFL). The technology helps reduce power consumption by almost 40% compared to the company's other LCD HDTV models, it said.

Sony's Presence Sensor can automatically turning off the picture when no one is present in the vicinity after a user-set timeframe. When the sensor detects motion, the TV turns itself back on.

The sets feature Sony's Motionflow 120Hz technology for improved sharpness and detail in fast-moving images. The models also offer a USB input for playing audio files from a USB storage device or connecting a compatible digital camera to display photos.

The models are compatible with Sony's Bravia Link modules including the Bravia Wireless Link, Bravia Input Link and Bravia DVD Link.
