CES: sensors + smart LED drivers help TV exceed Energy Star 6.0


CES, Las Vegas – ams has launched a technology that enables a 42-inch flat panel TV to use less than 60 watts of power, while delivering an optimal viewing experience. ams will demonstrate this advancement during CES using an off-the-shelf television enhanced with ams’ Digital Ambient Light Sensor technology and smart LED drivers. The result is a TV that uses up to 50% less energy than standard 42-inch models, exceeding Energy Star 6.0 guidelines while providing highest picture quality, even in the lowest light conditions.

A study by the Consumer Electronics Association showed that when it comes to TVs, two items at the top of consumers’ wish lists are a low-power HDTV, and better picture quality. Yet with new Energy Star Guidelines being introduced in the spring of 2013, delivering both items on the wish list will become more challenging. Energy Star 6.0 calls for a 42-inch TV set to consume just 62.9 watts of power, and the maximum any TV can consume – regardless of size – is just 85 watts. Additionally, the measurement of power usage will cover four levels of ambient room light, as most consumers prefer to watch television in living rooms with low light levels.

2013 televisions that combine an ams Digital Ambient Light Sensor with local dimming and high-accuracy drivers will meet and exceed the Energy Star 6.0 ratings without waivers or unusable brightness settings. The ams Digital Ambient Light Sensor does this by sensing the ambient light level of the room and adapting the backlight to a lower power level. The impact of this is to improve TV contrast ratio, eliminate blinding or excessively bright displays, and realize substantial power savings due to automatically adjusted lower backlight drive based on ambient light conditions.

The combination of ams Digital Ambient Light Sensors and smart LED drivers is available now from ams .
