LCD Televisions

LCD televisions are flat panel televisions that utilize LCD technology, which is already commonly been used in cell phones, calculators, and computer monitors. LCD televisions' display screen has two parallel polarizing panels and a liquid crystal sandwiched between them. Based on the amount of voltage passed through the panels, the rod-shaped liquid crystal molecules will be untwisted to different degrees, limiting the entry of light. Thus, the crystalline layer acts a shutter that either allows or blocks the passage of light. As a result, dark and light patterns are formed on the display, which produces a magnificent picture.

A white backlighting is required in LCD televisions since the LCD pixels do not emit light as in Plasma televisions.

In this, each color pixel is generated by three sub-pixels with red, blue, and green color filters. Unlike plasma and CRT ones, LCD televisions do not have a phosphor dot coating. Hence, they are thin and require much less power to operate than standard television screens.

Initial problems with LCD televisions were restricted viewing angle and difficulty in displaying fast-moving action. However, technology has advanced and the problem has been overcome in recent years.
LCD televisions with wider viewing angles are now available.

Better screen quality, longer life, and higher reliability are the core features of LCD televisions.

Compared to CRT televisions, LCD televisions have improved picture clarity and a flicker-free screen.
LCD television monitors come have dual inputs to connect to the computer whereas others feature built-in speakers or jacks for microphones and headphones. The LCD television screen can be positioned in the landscape mode (longer than wide) and portrait mode (taller than wide).

LCD televisions are the best options for TV, video, and data display. LCD televisions can also be used as computer monitors. They come in a variety of sizes, from the tiny ones that fit in cabinets to the large home theater types..

Plasma vs LCD TVs

For a layman, there seems to be no difference between a plasma and LCD TV. Both provide high-resolution, high-contrast images and both are flat, sleek and can be mounted on a wall. The difference lies in the technology that drives them.

Plasma TVs work with inert gases like xenon or neon, which are excited by electric pulses from specialized cells called pixels. This makes the gases glow. These glowing gases, in turn, produce the correct blend of red, blue and green light on the pixels.

The pixels are illuminated by a fluorescent light bulb, which is driven by semiconductor software on the motherboard.

LCDs are actually thin film transistors (TFT), which contain liquid filled crystals between two plates of glass. LCDs work by blocking out unwanted light. When the signal hits the TFTs, they contort to a required angle, thus allowing only the requisite amount of light to pass through. A lamp behind the screen or a thin LCD bulb provides illumination to...

Have You Seen LCD Projection TV?

Have you seen LCD projection TV? No, really. I don't just mean a picture online or in an advertisement on a normal tube television, but have you actually seen projection TV? It really is completely different that what even the hardest of hardcore couch potatoes have ever witnessed. It is impossible to properly describe the effect of LCD projection TV, but roughly it is to normal TV what the CD is to the cassette tape. Leagues of difference, I say.

This may come as a surprise to you. Just like other types of big screen TVs, LCD flat screen TVs have some disadvantages, as well. Yes, it's true. For example, LCD TVs have lower contrast ratios than plasmas, because they have a harder time reproducing deep black and dark grays. Their screen also tend to be thicker than plasma screens.

However, a LCD flat screen TV is not susceptible to burn-in and usually is less expensive than plasma televisions.

LCD TVs also run cooler than plasma TVs, thereby minimizing the need for noisy fan cooling. Many LCD sets can double as a PC monitors, as well. In terms of longevity, LCD flat screen TVs can last up to 60,000 hours, whereas plasma TVs, on average, last 30,000 to 40,000 hours.
