LCD TV Information
LCD TV - The Basic Television Technology |
|
LCD televisions produce a colour and mono image by filtering white light selectively. This light is created via a complex series of (CCFLs) cold cathode fluorescent lamps. These are positioned to the rear of the screen and are critical to produce the picture on an LCD TV. A number of television displays use colour and white LEDs to display the picture. Millions of single LCD shutters grouped in grids open and close simultaneously, allowing a specific amount of the white light to be projected through. Every shutter is coupled with a coloured filter to eliminate all apart from the red, green and blue measure of light (RGB) from the primary white. Each pair form a solitary pixel. The pixels are so minute that when the LCD TV screen is viewed from a very short distance the singular colours merge together to produce a single spot of that particular colour, this is what we call a pixel. The depth of that individual colour is handled by changing the intensity of light that is filtered through the pixel.
What is a Liquid Crystal Diode (LCD TV)?LCDs are everywhere. Liquid crystal display is so mass used that most people would not be able to function correct for 1 single day without utilising this technology. This LCD technology is used in microwave ovens, cars, digital clocks, radios and stereos, calculators and office equipment, thermometers, kitchen and bathroom scales, LCD TV's and much, much more! The millions of different applications for liquid crystal displays (LCD) are almost immeasurable. LCD manufacturing and technology has enabled us to create ultra-slim, vibrant displays that are utilised everywhere from residential to commercial premises into yachts, airplanes and so on. It is much more easy to view a TV display like LCD and Plasma as they are significantly brighter and boast higher contrast than a traditional CRT television. An LCD TV will perform exceptionally well under nearly all lighting conditions. LCD TV viewing in an intensely lit room will not wash out its picture. Lighting from spot lights and lamps will usually cause a bright glare on a TV screen. The outstanding quality of a flat screen, or LCD TV, is that you don't have to turn the lights off to see the screen easily and as a clear picture. You also do not have to worry about eyestrain because LCD TV's and Plasma TV's do not flicker in the same way that old CRT style televisions do.
You should expect to watch you LCD TV for many years. The average lifespan of this type of television is approximately 50 to 60,000 hours. If your occupation was to sit watching the television, full time, 24 hours a day, 7 days a week, 52 weeks a year it would take approximately 7 years before your LCD TV was worm out! Studies have shown that with regular, normal viewing the lifespan of your LCD TV could be more than 20years, now that's value for money! The lifespan of an LCD Television display is usually much longer than a similar-sized plasma television. An LCD display, and the continuous quality of the picture, can also depend upon the quality of manufacture of critical components. Brands like LG, Sharp, Toshiba, JVC and Sony televisions are usually built from better quality components and therefore should, under the correct operating circumstances last longer, and produce a better quality picture than a cheap Chinese or Korean variety. Cheap televisions can often be problematic and end up costing more money to replace or repair. Cheap televisions are often false economy in the long run. |
LCD Televisions have made significant technological advances utilising a LED backlighting system. This enables the TV to be viewed with better levels of back light and results in a brighter and more energy efficient TV.
