LCD TVs - What You Should Know

Television imaging technology has come a long way since the 1931 when the first commercially practical cathode ray tube was made for television. Today liquid crystal display (LCD) TVs are becoming the dominant image technology. If you are thinking about buying a new LCD TV what should you know?

Plasma and LCD TVs - What's the difference? You will soon learn that there are two types of flat screen, high definition television (HDTV) -- Plasma and LCD. When you watch a movie on either Plasma or LCD, you are looking at possibly 2 million tiny pixels as they change color and form a moving image. In Plasma TVs, each pixel cell is like a tiny neon light bulb (containing plasma), switching on and off rapidly, contributing its part to the overall image you see on the screen. LCD TVs are based on an entirely different principle. A tiny LCD pixel requires a separate light source in back of the pixel. That lighting is called backlighting. The LCD pixel acts like a tiny shutter, reducing or blocking the light or allowing it to shine through as needed to form its small part of the big picture. Compared to LCD TVs, plasma TVs are generally brighter with higher contrast. They display images with less blur due to faster refresh rates and the inherent properties of the plasma pixels. However, Plasma TVs are generally more expensive, heavier, more fragile, require more electricity, and are more likely to have problems with burn-in (from images displayed too long) and burn-out (from long, extended use). The quality of LCD TVs has been rapidly improving due to advances in LCD TV design and manufacturing. Some manufacturers have discontinued production of plasma HDTVs and concentrated on LCD models.

LED backlighting can be either edge-lit or full-array. Edge lighting uses small LED lights arranged around the rim or perimeter of the TV behind the screen, along with a diffusion surface to distribute light as evenly as possible throughout the screen image. Full-array backlighting uses small LED lights distributed, not along the edge, but throughout the back of the screen. Improvements to full array backlighting include Local Dimming, where portions of the array are controlled separately.
