LCD TV Review

Regardless, the era of standard definition, cathode-ray-tube TVs is fading into history. The demand for LCD TV is increasing due to its good features. Liquid-crystal displays come in many sizes, but only two resolutions qualify as HD: 720p (1280 x 720 pixels) and 1080p (1920 x 1080 pixels). Unlike pixels on a plasma screen, which produce their own light, the pixels on an LCD panel perform as filters for the light source behind them. Each pixel is made up of red, green and blue sub pixels, which can produce almost any color when used in combination.

Low-quality LCD TVs can have both bright and dark spots on the screen. A good diffuser evens out the backlight before it goes through the pixels. A variety of polarizing filters on the back and front of the LCD directs light to the pixels, or blocks it when a pixel is supposed to be dark. When shopping for your set, check for consistent illumination and black levels that are truly black.

Most LCD televisions currently use a fluorescent backlight— the same technology found in a compact fluorescent light bulb. In the coming years, many sets will switch to brighter, longer-lasting, more energy efficient light-emitting diodes (LEDs). By dynamically dimming sections of the backlight, LEDs can offer higher contrast ratios and deeper blacks.

Surprisingly, not every LCD flat panel is a television. Some LCDs are sold without internal tuners, and are thus technically monitors. For those who already get their signal through a cable or satellite set-top box, the distinction is somewhat irrelevant, and a monitor may save you money. If you have cable but don’t want a set-top box, look for a TV equipped with a QAM tuner and tru2way capability.

ere are many options to choose from, and each has its pros and cons. Understanding the technology behind the panel is the place to begin your journey to TV enlightenment. Panasonic Viera TH-42PX80U and Panasonic Viera TH-42PX80U are the best LCD Televisions under $1000 category. Samsung HL61A750 and Samsung LN46A550 are best under $2000 category.
