Today's LCD Flat Panel TV with Full HD, means there’s no need to scale down a 1080 signal. With twice the pixel resolution of 720p HD models, Full HDTV LCD TV creates the pinnacle in picture quality .

LCD TV functions with a twisted nematic (TN) (the most common type) liquid crystal. This is used in display applications such as LCD television, monitors and projectors. It is so named because it has a naturally twisted crystalline structure. This crystal reacts to electric currents in predictable ways, such as untwisting to varying degrees depending on the voltage of the current to which it is exposed. The main difference between plasma and LCD technology is that LCD pixels don’t emit light. An LCD TV pixel is comprised of three sub-pixels in the elementary colors. Because they don’t emit light, LCD TV & LCD Monitor displays need white backlighting. The light emitted by the backlighting passes through the liquid crystal and is then colored by a filter. Each subpixel has the same characteristics; only the color of the filter changes depending on the pixel. The liquid crystal of each subpixel can be controlled electrically like a valve; the amount of light allowed to pass through the crystal governs how much red, green and blue is emitted for each pixel. Active matrix LCDs employ thin film transistors (TFTs),m or tiny switching transistors and capacitors arranged in a matrix on a glass substrate, to direct electric charges down columns to reach a particular pixel. In turn, this causes the liquid crystals to untwist and display a predetermined amount of light generated by the light source – usually a fluorescent bulb located in back of them. By exploiting a combination of red, green, and blue subpixels of various intensities (or gray scales), a single pixel triad can reproduce approximately 16.8 million colors.

LCD TV offers higher resolutions than plasmas of the same size, and HDTV LCD TV generally cost less and use less enegery than Plasma. They also have excellent image stability. In other words, you can sit close without experiencing eye fatigue. Additionally, LCD TV boasts a longer lifetime than plasma televisions – on average about 50,000 hours versus 30,000 hours. Also, If you're contemplating a home entertainment setup involving a PC--perhaps running Windows XP Media center Edition - or other activities involving text as well as graphics, you'll get a crisper, brighter image from an LCD. LCDs are also space-efficient and because they operate at much cooler temperatures cost less per hour than plasma televisions. The smaller and better transistors found in LCDs give them another advantage over plasma – higher resolution.
