Difference Between LCD and LED TVs

LCD stands for “liquid crystal display” and technically, both LED and LCD TVs are liquid crystal displays. The basic technology is the same in that both television types have two layers of polarized glass through which the liquid crystals both block and pass light. So really, LED TVs are a subset of LCD TVs.

LED, which stands for “light emitting diodes,” differs from general LCD TVs in that LCDs use fluorescent lights while LEDs use those light emitting diodes. Also, the placement of the lights on an LED TV can differ. The fluorescent lights in an LCD TV are always behind the screen. On an LED TV, the light emitting diodes can be placed either behind the screen or around its edges. The difference in lights and in lighting placement has generally meant that LED TVs can be thinner than LCDs, although this is starting to change. It has also meant that LED TVs run with greater energy efficiency and can provide a clearer, better picture than the general LCD TVs.

 
The Most Important Thing: The Display
 
The one main important thing to remember though is the display. After all, it will be the centerpiece of your multimedia setup. From playing games to watching movies and shows, your TV is where your eyes will be most of the time once you turn it on.
Checking out televisions for sale at your local shopping mall may be helpful to some degree, since you can see for yourself how accurately the display renders colors and the difference between displays once they’re stacked against each other. Before heading out though, what strikes the buyer is the inevitable choice of buying an LCD TV or LED TV.
Which one between these two types offers better picture quality and which one is the best overall? What offers value for your money and will last longer? It sometimes boils down to one’s preference, and to give you an idea on what you get if you choose to go with an LCD or LED TV, here’s a rundown of some of the major aspects being offered by both.

Conclusion:
 
Given these pros and cons of both LCD and LED TVs, it’s really up to the buyer to figure out which suits their needs best. Obviously, LED TVs have the more advanced technology, slightly better picture quality (generally speaking), but comes at a higher price point. LCD TVs remain in production despite the gaining popularity of their LED counterparts and this is because they offer good value given at a lower price, doing so with above average picture quality.
Do take note that setting up your new display properly is one of the first things you’ll need to do before going on a movie marathon to get the best results. Even the most advanced TV set can’t produce that stunning picture quality you’re looking for if it’s not set up properly.

Evolution of Air Conditioners

As summer approaches, bringing with it soaring temperatures and unbearable humidity, millions of people will turn on that marvel of discovery and invention – The Air Conditioner. These comfort units that homeowners activate with the ease of flipping a switch are complex Electro-mechanical systems, the end products of nearly a century of engineering development in cooling, thermodynamics, controls, and energy efficiency. In 2000, air conditioning/refrigeration was named among the 10 greatest mechanical engineering achievements of the 20th century, according to a survey of ASME members. Air conditioning actually has roots in second century China, where an inventor named Ding Huane crafted a manually powered rotary fan. The concept of air cooling also intrigued the great American inventor and statesman Benjamin Franklin, who in 1758 conducted experiments with evaporation and alcohol to attain freezing temperatures.



Attempts to control indoor temperatures began in ancient Rome, where wealthy citizens took advantage of the remarkable aqueduct system to circulate cool water through the walls of their homes. The emperor Elagabalus took things a step further in the third century, building a mountain of snow—imported from the mountains via donkey trains—in the garden next to his villa to keep cool during the summer. Marvelously inefficient, the effort presaged the spare-no-cost attitude behind our modern-day central air-conditioning systems. Even back then some scoffed at the concept of fighting heat with newfangled technologies. Seneca, the stoic philosopher, mocked the "skinny youths" who ate snow to keep cool rather than simply bearing the heat like a real Roman ought to.

It's not an exaggeration to say that Carrier's innovation shaped 20th-century America. In the 1930s, air conditioning spread to department stores, rail cars, and offices, sending workers' summer productivity soaring. Until then, central courtyards and wide-open windows had offered the only relief. Residential air conditioning was slower to take hold: As late as 1965, just 10 percent of U.S. homes had it, according to the Carrier Corporation. By 2007, however, the number was 86 percent. As cool air spread across the country, Sun Belt cities that had been unbearable in the summer became more attractive places to live and work, facilitating a long-term shift in U.S. population.

Smart Technologies
 
In a further effort to reduce energy usage, some air-conditioning manufacturers have begun to stretch the capabilities of the standard wall thermostat, developing sophisticated microprocessor-based diagnostic and control kits that automate the operation of the compressor and air-flow system. The Trane ComfortLink II remote thermostat allows the homeowner to adjust functions and settings on the air conditioner from off-site computers and web-enabled cell phones; ComfortLink will even send text and e-mail alerts on when to replace the filter or arrange routine service inspections.
“We are using innovation to put a whole new level of control in the consumer’s hands, in the process reducing home energy consumption,” explains Thoren, a longtime ASME member. He says Trane views the air conditioner as one component in the automated, energy-efficient home of the future.
