Ams sensors enables 42-inch flat panel TV to consume less electricity than a 60-watt light bulb

The company, ams has introduced sensor technology that enables a 42-inch flat panel TV to use less than 60 W of power, while delivering an optimal viewing experience.

The company aims to demonstrate the advancement during CES using an off-the-shelf television enhanced with ams’ Digital Ambient Light Sensor technology and smart LED drivers.

The technology enables a TV to use up to 50% percent less energy than standard 42-inch models – exceeding Energy Star 6.0 guidelines – while providing the highest picture quality, even in the lowest light conditions.

In addition to the direct consumer benefits of combining these ams technologies, there is an environmental benefit as well. Based on the average daily television viewing in the United States, adopting ams’s intelligent sensor-driven backlighting technology would result in a reduction in CO2 consumption equivalent to removing more than 1 million cars from the road.

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 62.9 watts of power, and the maximum any TV can consume – regardless of size – is 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, while delivering a higher quality viewing experience. The ams Digital Ambient Light Sensor achieves this by sensing the ambient light level of the room and adapting the backlight to a lower power level. The impact of this is threefold: 1) the TV has improved contrast ratio, which is noticeable and pleasing to the eye; 2) there is no blinding or
