Which TV would be better for you – LCD vs LED?

People everywhere are becoming more and more concerned about the technical specifications in various consumer products and that is why they are looking for the information which describes these products to their best. There are various sources for the type of information from where people can get at them and feel comforted before buying any consumer product. The quest for the best sources of visual entertainment is on for a few decades now. It is quite an acceptable fact that science has given some very wonderful gadgets for personal and mass entertainment among which various types of televisions are certainly the most important ones. However, the choice is also getting varied each and every day. Today, the choice between LCD and LED TVs is certainly getting tougher and tougher. The battle of LCD vs. LED is continuing for quite some time now.
It is seen that people often get confused in this war of LCD vs. LED and that is why they often get confused whenever they decide to get a new TV for themselves. However, if a little attention is paid towards the technical specifications between theLCD and LED TVs, then the possible buyers can feel it easy to identify the winner of the battle of LCD and LED TVs. The information shared here can certainly help people to get the best information about the LED and LCD TVs.

The main points that one should consider while finding the better of LCD vs. LED

This is quite obvious fact that people must find these differences while evaluating LCD vs. LED TVs. The possible buyers can find the following specifications in findingthe best among LCD vs. LED.
Better picture contrast: The differential contrast between LED vs. LED TVs can be identified by the fact that the LED TVs are known for their better contrast ratios. The contrast ratio is one of the most important factors that can be watched very carefully in this battle of LCD vs. LED TVs. As a matter of fact, the LED TVs make use of high capacity diodes and that is why these TVs are capable of making better contrast ratios. On the other hand, the LCD TVs make us of cold cathode fluorescent backlight tube which is good in quality but it cannot make a significant difference against LED TVs.
Consider the power consumption capacities between LCD vs. LED TVs: It is yet another significant factor that places the LED TVs ahead of the LCD TVs. The powerful capacitors installed inside the LED TVs. Due to this cutting edge technology, the LED TVs consume less power while switched on. The lesser power consumption can keep the electric bill down to a considerable limit. This advantage of lesser power consumption and lower electric bill certainly make a positive impression upon the common users.
Better performance can be considered while deciding winner of LCD vs. LED TVs: The LED TVs are born to lead the entertainment world as these TVs are known for their better performance in all possible fields related with the visibility and sound.
Viewing angle is also a decisive factor of LCD vs. LED TVs: As the size of the houses of the common man is getting increasing smaller so people cannot manage a big viewing space for viewing their favorite TV programs. The advantage certainly lies in favor of those who view LED TVs as these TVs can be watched from any angle. The viewing experience can be equally high from all possible angles. Whereas the case is different with the LCD TVs as the viewers of these TVs are required to maintain an angle of at least 30 degrees. The simple reasons of this benefit goes in favor of the LED TVs only because of the fact that the screen maintains a high resolution capacity which is equal from all possible angles.
Accuracy of the color patterns: This is a very important factor that the buyers must look for whenever they are out for buying these high definition TVs. The LED TVs are the best TVs which make use of the best technologies for providing the best viewing experience with respect to the color patterns. The advantage of the better color specifications distinguishes the LED TVs from the LCD TVs.
These distinctions are the most significant ones and each buyer of these high definition TVs must satisfy themselves most adequately before buying any. The best of these TVs can be identified only after looking at these things before considering the best in the battle of LCD vs. LED TVs.

A Brief History of the Microwave Oven

Like many of today's great inventions, the microwave oven was a by-product of another technology. It was during a radar-related research project around 1946 that Dr. Percy Spencer, a self-taught engineer with the Raytheon Corporation, noticed something very unusual. He was testing a new vacuum tube called a magnetron, when he discovered that the candy bar in his pocket had melted. This intrigued Dr. Spencer, so he tried another experiment. This time he placed some popcorn kernels near the tube and, perhaps standing a little farther away, he watched with an inventive sparkle in his eye as the popcorn sputtered, cracked and popped all over his lab.

The next morning, Scientist Spencer decided to put the magnetron tube near an egg. Spencer was joined by a curious colleague, and they both watched as the egg began to tremor and quake. The rapid temperature rise within the egg was causing tremendous internal pressure. Evidently the curious colleague moved in for a closer look just as the egg exploded and splattered hot yolk all over his amazed face. The face of Spencer lit up with a logical scientific conclusion: the melted candy bar, the popcorn, and now the exploding egg, were all attributable to exposure to low-density microwave energy. Thus, if an egg can be cooked that quickly, why not other foods? Experimentation began...

Dr. Spencer fashioned a metal box with an opening into which he fed microwave power. The energy entering the box was unable to escape, thereby creating a higher density electromagnetic field. When food was placed in the box and microwave energy fed in, the temperature of the food rose very rapidly. Dr. Spencer had invented what was to revolutionize cooking, and form the basis of a multimillion dollar industry, the microwave oven.

Nearly 6 Feet Tall, Weighing 750 Pounds

Engineers went to work on Spencer's hot new idea, developing and refining it for practical use. By late 1946, the Raytheon Company had filed a patent proposing that microwaves be used to cook food. An oven that heated food using microwave energy was then placed in a Boston restaurant for testing. At last, in 1947, the first commercial microwave oven hit the market. These primitive units where gigantic and enormously expensive, standing 5 1/2 feet tall, weighing over 750 pounds, and costing about $5000 each. The magnetron tube had to be water-cooled, so plumbing installations were also required

Initial Reactions Were Unfavorable
Not surprisingly, many were highly reluctant about these first units, and so they found only limited acceptance. Initial sales were disappointing...but not for long. Further improvements and refinements soon produced a more reliable and lightweight oven that was not only less expensive, but, with the development of a new air-cooled magnetron, there was no longer any need for a plumber.

The microwave oven had reached a new level of acceptance, particularly with regard to certain industrial applications. By having a microwave oven available, restaurants and vending companies could now keep products refrigerator-fresh up to the point of service, then heat to order. The result? Fresher food, less waste, and money saved.

New and Unusual Applications

As the food industry began to recognize the potential and versatility of the microwave oven, its usefulness was put to new tests. Industries began using microwaves to dry potato chips and roast coffee beans and peanuts. Meats could be defrosted, precooked and tempered. Even the shucking of oysters was made easier by microwaves. Other industries found the diverse applications of microwave heating quite advantageous. In time, microwaves were being used to dry cork, ceramics, paper, leather, tobacco, textiles, pencils, flowers, wet books and match heads. The microwave oven had become a necessity in the commercial market and the possibilities seemed endless

The First "Radarange

In 1947, Raytheon demonstrated the world's first microwave oven and called it a "Radarange," the winning name in an employee contest. Housed in refrigerator-sized cabinets, the first microwave ovens cost between $2,000 and $3,000. Sometime between 1952-55, Tappan introduced the first home model priced at $1295. In 1965 Raytheon acquired Amana Refrigeration. Two years later, the first countertop, domestic oven was introduced. It was a 100-volt microwave oven, which cost just under $500 and was smaller, safer and more reliable than previous models

By 1975 Sales of Microwave Ovens Exceeded that of Gas ranges

Technological advances and further developments led to a microwave oven that was polished and priced for the consumer kitchen. However, there were many myths and fears surrounding these mysterious new electronic "radar ranges." By the seventies, more and more people were finding the benefits of microwave cooking to outweigh the possible risks, and none of them were dying of radiation poisoning, going blind, sterile, or becoming impotent (at least not from using microwave ovens). As fears faded, a swelling wave of acceptance began filtering into the kitchens of America and other countries. Myths were melting away, and doubt was turning into demand

By 1975, sales of microwave ovens would, for the first time, exceed that of gas ranges. The following year, a reported 17% of all homes in Japan were doing their cooking by microwaves, compared with 4% of the homes in the United States the same year. Before long, though, microwave ovens were adorning the kitchens in over nine million homes, or about 14%, of all the homes in the United States. In 1976, the microwave oven became a more commonly owned kitchen appliance than the dishwasher, reaching nearly 60%, or about 52 million U.S. households. America's cooking habits were being drastically changed by the time and energy-saving convenience of the microwave oven. Once considered a luxury, the microwave oven had developed into a practical necessity for a fast-paced world.

Improve your TV Experience

There is nothing better than being able to sit back and watch TV in your own home. But a television is much more than a box that displays images. It can transport you to other worlds while connecting you with stories from around the world. Here are some great ways to improve your overall experience so that you get full value from your TV. So whether your thing is TV, movies, or karaoke, make sure to get the accessories you need to enjoy yourself more.

We Love TV!

  Enjoy TV the most

Television has gone through several interesting incarnations over the decades. Obviously when it first came out people clamoured to buy these newfangled devices that offer a form of entertainment that was never seen before. These days, televisions are a stalwart of American entertainment and it's unlikely that you could walk into any common household and not find a television set somewhere. In fact, most people have several television sets in their own home and sometimes it's easy to take them for granted. But remember that television offers you an extraordinary opportunity to engage with visual media and there are many ways to improve your experience as well. Most people don't think all that much about their TV viewing pleasure, but here are some ways that you can enhance

Comfortable furniture - imagine watching your favorite television show for two hours at a time sitting on a stool. Obviously no one has that type of setup in their living room, but you might be surprised at how often people neglect comfort. There's nothing better than being able to relax on a nice big comfy couch while watching your favorite television and movie shows. You can even get seats that simulate the theater experience if you want to set up a home theater that rivals anything you could find at the local mall.

Big screen TV - there's nothing like being able to watch your favorite sports on a big screen TV. Even if you're thing is soap operas or comedies, they always come out better when you see the images big and clear right in front of you. These days you can also opt for high-def options that will really have you right in the middle of the action. The best news is that big screen TVs are cheaper than ever and you don't have to break your bank account to get one into your home these days. Look around for deals because they are certainly out there.

Sound and stereo - sound can add another layer of enjoyment to your television viewing experience especially if you have a good stereo system. You can surround yourself with all of the sounds that accompany your favorite movies and really make them transport you to another realm. Better yet, invest in 
wireless headphones for TV and you have your own private surround sound at a relatively affordable price

One of the most interesting developments with television these days is that it is replacing the movies for many people. Rather than going out into a public movie theater where you are faced with high prices and a rude people, there are many things you can enjoy in the comfort of your own home. What could be better than being able to watch your favorite television and movies without having to deal with high prices and total strangers? You can enjoy time with your family.

Another interesting trend seems to be with the quality of television shows which are dramatically increasing. When was the last time you saw a really good movie in the theater? It seems these days Hollywood is obsessed with creating blockbusters rather than quality movies that were once featured in local cinemas. Sometimes you have to look towards television to find developed storylines that run through popular series rather than in anything the big-screen can offer. That's great for fans of television who enjoy networks like HBO, and there are wonderful shows that will rival even the best movies in terms of story line and character development. There is good news and bad news related to this since a lot of people are lamenting the loss of the ultimate movie experience that they once grew up with. On the other hand, the way television is developing today offers a new form of entertainment that might be responsible for even more developed stories.

Whatever the future holds, it's going to be interesting to see how we interact with our home entertainment rooms these days. Technology is blending with social media and it probably won't be too far off when we incorporate the Internet into the television experience as well. In fact, it's already started to happen and thanks to services like Netflix you can stream television and movies rather comfortably using the latest technology. This is also had a tremendous impact on regular cable companies and they will have to adjust to current trends as well. By the time the dust settles it's impossible to tell where everyone will end up, but it is clear that the common consumer is going to win in the end. There's so much quality to enjoy out there and if you take the time to improve your ultimate home entertainment set up, then you will take full advantage of this fact.

How to Calibrate Your TV

Whether you've just bought a new HDTV to furnish your living room with or you just want to improve your current TV viewing experience, calibration should be the first step you take. An incorrectly calibrated television will have a poor picture quality, resulting in a sub-par viewing experience. One option would be to hire a professional to calibrate for you, but that is a pricey investment. Instead, you can learn how to calibrate your TV quickly and effectively in a few simple steps.

Reset the television to factory settings.

 Factory settings are the settings for the TV when it has been purchased new. These settings are not the ones you want permanently as they are designed for the in-store setting with lots of bright, ambient light. However, you should reset to the factory settings so that you can use it as a foundation when calibrating the display for your own environment.

Disable any sort of dynamic display changing.

Some televisions are equipped with an ambient sensor which is used to automatically adjust the television color based on the environment. Unfortunately, dynamic modes tend to result in bright and garish pictures, so it's usually best to avoid using them.

Adjust the brightness levels.

The brightness setting isn't actually a control for brightness, but rather the level of blackness. Raising brightness is really just reducing the blackness. Adjust the brightness levels until your eyes feel comfortable watching the screen.

Adjust the contrast levels.

The contrast setting isn't actually a control for contrast, but rather the brightness of the white. Adjust the contrast levels until you can distinguish between dark blacks, light blacks, dark whites, and light whites.

Adjust the sharpness levels.

The sharpness setting adds information to the picture so that it looks more crisp. If your television is high definition, then you most likely do not need sharpness and can reduce it. If your television is not high definition, sharpness can help to improve picture quality.

Leave the Tint setting alone

Most televisions have their tint setting calibrated correctly straight out of the factory, so the factory setting for tint is likely the most optimal already.

  • If your television has a feature that allows saving calibration profiles, then calibrate your television twice: once for day time and once for night time. Unless your television is in a room without windows, the brightness of the sunlight will affect your viewing experience. During the day, the television should use brighter settings. During the night, use darker setting
  • If your television has a feature that allows saving calibration profiles, then calibrate your television for each input device. For example, the picture from your DVD player will differ from the picture out of your cable box so you should have different calibration settings for each. For optimal viewing, you may wish to calibrate your television for each source of picture.

  • Calibrate your television at least once per year. Over time, the quality of your television lights and colors degrade, thus requiring a re-calibration on an annual basis.

Energy Savings Tips

The Domestic Sector accounts for 30% of total energy consumption in the country. There is a tremendous scope to conserve energy by adopting simple measures.
This information is a guide, which offers easy, practical solutions for saving energy in Home Appliances. Please, take a few moments to read the valuable tips that will save energy & money and ultimately help conserve our natural resources.
It would be useful to know which gadget consumes how much electricity. Economic use of home appliances can help in reducing electricity bills.
The following table shows the energy consumption of various appliances normally used at home:

Units/ Month
Incandescent Bulbs
Fluorescent Tube light
Night Lamp
Mosquito Repellent
Air Coolers
Air Conditioners
Hot Plate
Electric Kettle
Electric Iron
Water heater-Instant Type (1-2 Ltr capacity)
Water heater-Storage
type (10-20 Ltr capacity)
Immersion rod
Vacuum Cleaner
Washing Machine
Water pump
Audio system

By following these simple tips one can save energy to a large extent.

  • Turn off the lights when not in use
  • Take advantage of daylight by using light-colored, loose-weave curtains on your windows to allow daylight to penetrate the room. Also, decorate with lighter colors that reflect daylight
  • De-dust lighting fixtures to maintain illumination
  • Use task lighting; instead of brightly lighting an entire room, focus the light where you need it
  • Compact fluorescent bulbs are four times more energy efficient than incandescent bulbs and provide the same lighting
  • Use electronic chokes in place of conventional copper chokes
  • Replace conventional regulators with electronic regulators for ceiling fans
  • Install exhaust fans at a higher elevation than ceiling fans
Electric iron
  • Select iron boxes with automatic temperature cutoff
  • Use appropriate regulator position for ironing
  • Do not put more water on clothes while ironing
  • Do not iron wet clothes
Kitchen Appliances
·         Avoid dry grinding in your food processors
( mixers and grinders) as it takes longer time than liquid grinding

Microwaves ovens
·         Consumes 50 % less energy than conventional electric / gas stoves
·         Do not bake large food items

·         Unless you're baking breads or pastries, you may not even need to preheat
·         Don't open the oven door too often to check food condition as each opening leads to a temperature drop of 25°C
Electric stove
·         Turn off electric stoves several minutes before the specified cooking time
·         Use flat-bottomed pans that make full contact with the cooking coil
Gas stove
·         When cooking on a gas burner, use moderate flame settings to conserve LPG
·         Remember that a blue flame means your gas stove is operating efficiently
·         Yellowish flame is an indicator that the burner needs cleaning
·         Use pressure cookers as much as possible
·         Use lids to cover the pans while cooking
·         Bring items taken out of refrigerators (like vegetables, milk etc) to room temperature before placing on the gas stove for heating
Use Solar Water Heater – a good replacement for a electric water heater
Electronic Devices
  • Do not switch on the power when TV and Audio Systems are not in use i.e. idle operation leads to an energy loss of 10 watts/device
  • Turn off your home office equipment when not in use. A computer that runs 24 hours a day, for instance, uses - more power than an energy-efficient refrigerator.
  • If your computer must be left on, turn off the monitor; this device alone uses more than half the system's energy.
  • Setting computers, monitors, and copiers to use sleep-mode when not in use helps cut energy costs by approximately 40%.
  • Battery chargers, such as those for laptops, cell phones and digital cameras, draw power whenever they are plugged in and are very inefficient. Pull the plug and save.
  • Screen savers save computer screens, not energy. Start-ups and shutdowns do not use any extra energy, nor are they hard on your computer components. In fact, shutting computers down when you are finished using them actually reduces system wear - and saves energy
  • Regularly defrost manual-defrost refrigerators and freezers; frost buildup increases the amount of energy needed to keep the motor running.
  • Leave enough space between your refrigerator and the walls so that air can easily circulate around the refrigerator
  • Don't keep your refrigerator or freezer too cold.
  • Make sure your refrigerator door seals are airtight
  • Cover liquids and wrap foods stored in the refrigerator. Uncovered foods release moisture and make the compressor work harder.
  • Do not open the doors of the refrigerators frequently
  • Don't leave the fridge door open for longer than necessary, as cold air will escape.
  • Use smaller cabinets for storing frequently used items
  • Avoid putting hot or warm food straight into the fridge
Washing machines
  • Always wash only with full loads
  • Use optimal quantity of water
  • Use timer facility to save energy
  • Use the correct amount of detergent

  • Use hot water only for very dirty clothes
  • Always use cold water in the rinse cycle
  • Prefer natural drying over electric dryers
Air Conditioners

  • Prefer air conditioners having automatic temperature cut off
    Keep regulators at “low cool” position
  • Operate the ceiling fan in conjunction with your window air conditioner to spread the cooled air more effectively throughout the room and operate the air conditioner at higher temperature
  • Seal the doors and windows properly
    Leave enough space between your air conditioner and the walls to allow better air circulation
  • A roof garden can reduce the load on Air Conditioner
  • Use windows with sun films/curtains
  • Set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower will be energy consumption.
  • Don't set your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling.
  • Don't place lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
  • Plant trees or shrubs to shade air-conditioning units but not to block the airflow. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun

ONIDA the pioneer of Television in India wishes all the viewer happy World Television Day

World Television Day will be observed on November 21 (Monday) across the globe including India highlighting the importance of television media in promoting awareness about important issues and events.

Different public and private
institutions will observe the day through arranging discussion programmes and interactive sessions regarding development of electronic media in India.

World TV Day is marked every year to revive the endeavours of governments, organizations and individuals toward advancement of electronic media.

Electronic media has become a major
source of information as well as entertainment for the public as they get pictorial footage of different happenings through this mode of communication.

United Nations (UN) acknowledges that television can be used to educate many people about the world, its issues and real stories that happen on the planet.

Television is one of the most influential forms of media for communication and information dissemination. It is used to
broadcast freedom of expressions and to increase cultural diversity.

The UN realized that television played a major role in presenting global issues affecting people and this needed to be addressed.

On December 17, 1996, the UN General Assembly proclaimed November 21 as World Television Day to commemorate the date on which the first World Television Forum was held earlier that year.
