Sony BRAVIA WE Series LCD TV

Sony 40Sony have loaned me a Sony BRAVIA 40 inch WE5 Series HD LCD TV to try out for a few days. Specifically I wanted to see if this unit save much energy. The application I have in mind is for learning commons, where flat screens are used for digital signage and for presentations. In this applications the screens tend to be left on all day, so energy use is an issue.

One disappointment is that according to the specifications, the unit appears to be florescent backlit, not LED. As a result the backlight has to be all on, or off, the lighting behind black parts of the image can't be turned off.

However, the unit offers a Presence Sensor, which would be useful for public venues. This switches the picture off when no one is in the room. Sony claim this saves 50% of the power. This could be good for presentation screens, which tend to get left on. It may also be very effective for some applications of digital signage: when the person come within viewing range of the screen it will light up, thus attracting their attention.

At present the TV is still in the box, on the floor, some comments about how it goes to follow...

ps: Sony TVs are also available via Amazon.com but may not be versions suitable for Australian TV: Sony BRAVIA W-Series 40-Inch LCD HDTV
