New Sony TVs 'switch off' when no-one is watchingSony Bravia Eco WE5 LCD TV designed to save power
20 January 2009
Sony has showcased its latest range of TVs featuring energy saving technology, including the ability to recognise when all viewers have left the room, and switch to standby.
Each TV in the range features a small sensor beneath the screen, which monitors the room and triggers the TV to switch off its picture when everybody has left. When somebody re-enters the room, the sensor should detect their presence and switch the set back on.
The range is called the Sony Bravia 'Eco' WE5 range and is available in 40-inch, 46-inch and 52-inch LCD sizes. The series of televisions features a micro-tubular Hot Cathode Fluorescent Lamp (HCFL), which Sony claims helps to reduce the power consumption of these sets by nearly 40% in comparison to Sony's other LCD TVs.
It is also the first range of Sony TVs to feature what is called the 'zero-watt standby switch'. This has been designed to enable the user to cut the power to the TV completely. Even when switched off most other TVs still draw power.
'Simple and innovative'
Randy Waynick, senior vice president of Sony Electronics' home products division, said: 'Our new Eco TVs represent the company's commitment not only to saving the environment, but also to saving consumers money through lower power consumption.'
Michael Briggs, Which? TV expert, said: 'We always applaud companies that are looking to save energy, and the sensors on this new range of models from Sony provide a simple and innovative approach to tackling this solution. We look forward to testing the results'.
