Trade-In, Trade-Up, and Save with Energy Star Appliances

Monday, March 1st, 2010

Bosch KitchenSo, are your appliances eating you out of house and home with the water, electric, or gas bills? It is time to start thinking about switching to Energy Efficient appliances.

March is “Go Green” Month here at Number1Direct by Goedeker’s with a number of kitchen appliance brands like Bosch, GE Monogram, Frigidaire, LG, Fisher & Pakykel, and Electrolux kicking off the month with their most energy efficient and elegant models in money saving mail-in rebates starting at a modest $50 to a whopping $2000 depending on the brand and Energy Star Appliances (Dishwashers, Refrigerators, Ranges, Wall Ovens, Cooktops, Washers, and Dryers) you are purchasing. LivingRoom Plus, the living room is is not letting the kitchen have all the fun with some of the big brands like Samsung, LG, Hitachi, Mitsubishi and Sharp are offering money savings rebates on televisions of $799 and above.

What is Energy Star?

Energy StarENERGY STAR labels appear on appliances and home electronics that meet strict energy efficiency criteria established by the U.S. Department of Energy (DOE) and U.S. Environmental Protection Agency (EPA).

With ENERGY STAR, you can save more than 30% or more than $700 per year, with similar savings of greenhouse gas emissions, without sacrificing features, style or comfort. ENERGY STAR helps you make the energy efficient choice. ENERGY STAR-qualified Vision washers save $50 per year. Over the 11-year life of the washers, that’s enough money to:

Buy a new ENERGY STAR qualified dishwasher Bosch Ascenta dishwasher
Buy 65 bottles of laundry detergent (or enough detergent to do laundry for four years)

A fridge made before 1993 could be costing you over $100 each year to operate. Replace it with a new ENERGY STAR-qualified Linea model and cut your related energy costs in half.

What are Liquid Crystal Display (LCD) TVs?

Tuesday, February 9th, 2010

How Do They Work?

Liquid Crystal Display (LCD) TVs are a newer technology.They are made up of two glass panels filled with liquid crystal. The front glass panel has a grid pattern (template) etched into it so that the liquid crystal can be filtered by light. The crystals act like smart shutters allowing light to pass or to be blocked. The patterns of light and dark crystals determine the image on the TV. The twisted nematic (TN) is the most common type of liquid crystal used in display applications such as LCD televisions, monitors and projectors. This crystal reacts to electric currents in predictable ways, LCD TV Twisted Nematic

such as untwisting to varying degrees depending on the voltage of the current to which it is exposed. The main difference between Plasma and LCD technology is that LCD pixels don’t give off light. As with Plasma technology, an LCD pixel is comprised of three sub-pixels in the elementary colors. Because they don’t give off light, LCD displays need white backlighting. The light given off by the backlighting passes through the liquid crystal and is then colored by a filter. Each sub-pixel has the same characteristics; only the color of the filter changes depending on the pixel. The liquid crystal of each sub-pixel can be controlled electrically like a valve; the amount of light allowed to pass through the crystal governs how much red, green and blue is given off for each pixel. Active matrix LCDs employ thin film transistors (TFTs) or tiny switching transistors and capacitors arranged in a matrix on a glass substrate, to direct electric charges down columns to reach a particular pixel. In essence, this causes the liquid crystals to untwist and display a prearranged amount of light generated by the light source – usually a fluorescent bulb located in back of them. By exploiting a combination of red, green, and blue sub-pixels of various intensities (or gray scales), a single pixel triad can reproduce approximately 16.8 million colors.

Advantages and Disadvantages to LCD TVs

Advantages

  • LCD TVs include great still image quality as well as being an excellent computer screen with an exceptionally bright picture.
  • LCD TVs don’t take up a lot of space, they can be wall mounted and they weigh less than Plasma TVs.
  • LCD TVs have a long, practically maintenance-free life.
  • LCDs offer higher resolutions than Plasmas of the same size. They also have excellent image stability. In other words, you can sit close without experiencing eye exhaustion.
  • LCDs possess a longer lifetime than Plasma televisions, whith a difference of about 50,000 hours versus 30,000 hours.
  • LCDs are best over any other flat-panel displays when it comes to computers. LCD monitors are now used for most applications including games, office applications, and photo retouching.
  • LCDs operate at much cooler temperatures and cost less per hour than Plasma televisions. The smaller and better transistors found in LCDs give them another advantage over Plasma – higher resolution.

Disadvantages:

  • Possible quick delays in pictures with fast movement (size 37 inches and less handle the delay better than the larger sizes),
  • Some types of LCDs have trouble with black levels,
  • Some lesser quality LCDs have pixel failure.
  • The prices dramatically increase with LCD TVs over the size of 35 inches.
  • LCD viewing angles cannot match those of Plasma displays. You tend to see some brightness and color shift when you’re sitting at too far an angle from your LCD, while Plasma’s picture remains fairly solid.
  • LCDs have lower contrast ratios than Plasmas and are not as good at rendering deep blacks.
  • Not as good as Plasmas in tracking motion and fast-moving objects may exhibit what is called, lag artifacts.
