Next-Generation Energy Efficient TV Technology is Here

OLED TV

OLED TV

With football season moving into high gear, lots of us are thinking about the ultimate TV viewing experience. There are many factors to consider when looking for the perfect TV, and with today’s technology it’s possible to have it all – high picture quality and design as well as energy efficiency.

For those of you who are early adopters, you may be wondering about one of the newest TVs on the market – the OLED (organic light-emitting diode) TV.

OLED TV is the next generation in television technology, representing the most significant change in display technology since the introduction of flat-panel TVs. The TVs are ultra-thin and light weight and produce superb picture quality.

Sound’s great? It gets better.

OLED TVs mean that you don’t have to sacrifice performance and style for energy efficiency.

Although “LED” stands for “light-emitting diode” in both cases, the design of each TV is actually quite different. LED TVs simply use an array of LEDs as the backlight for an otherwise traditional LCD (liquid crystal display) TV, shining through a screen of LCD pixels. With OLED TVs, the organic layer creates its own light source for each pixel. As a result, OLED’s improvement over LED’s color, clarity and contrast ratios is quite dramatic. And even with this leapfrogging display technology, OLED TVs can be energy efficient, too.

The first ENERGY STAR certified OLED TV — the new “Curved OLED TV” from LG Electronics — went on sale in July. Among its energy-saving features is the “Smart Energy Saving” mode, which includes a sensor that automatically adjusts the display brightness according to the viewing environment. According to the Federal Trade Commission’s “Energy Guide” label, the TV has an estimated yearly energy cost of only $18.*

* The FTC’s calculations are based on 11 cents per kWh and 5 hours use per day. Your cost depends on your utility rates and use. Visit ftc.gov/energy.

Dangers of Being a Couch Potato

By Sarah Bae

Back in High School, after a long day of grueling study, I would come home to flop on the couch in front of my computer and spend hours doing nothing. Sometimes my whole family would spend large parts of our vacations and weekends relaxing in front of the TV. Besides the calories accumulated from constant snacking during these times, we never thought there were possible health risks associated with our practice. But, there is one danger that enjoying the comfort of your couch can cause – the danger of indoor air pollution. Indoor air pollution can be especially detrimental to older adults because studies show that they spend up to 90% of their time indoors. Indoor air is made up of a mix of contaminants such as secondhand smoke, fumes from household cleaning products, and more. Indoor contaminants can be dangerously toxic, especially to those already at risk of heart disease and stroke.

Wood burning stoves and fireplaces can create smoke that contains fine carbon particles which can trigger chest pain, palpitations, fatigue, and more while household products like the vapors from cleaning products, paint solvents, and pesticides can stress the lungs and heart. If your home was built before 1978, you should also make sure that there are no more traces of lead-based paint, as traces of lead can cause serious health hazards like high blood pressure. Furthermore, victims of pesticide poisonings show symptoms such as arrhythmia, a very slow pulse, or in severe cases even heart attacks. To decrease your chances of exposure to these risks, tell smokers to take it outdoors, and limit the use of wood burning stoves and fireplaces. Also use caution when working around the house by improving your ventilation when indoor painting is taking place – open the windows and take frequent fresh air breaks. Leave the house for a few days after the painting has been completed as well. Also, be careful when using pesticides and always take protective measures such as wearing long-sleeved shirts and long pants. Change clothes and wash hands after exposure to pesticides and wash the exposed clothes separately.
