Liquid-crystal display televisions (LCD TV) are television sets that use LCD display technology to produce images. LCD televisions are thinner and lighter than cathode ray tube (CRTs) of related display size, and therefore are offered in very much much larger sizes. When production costs fell, this mixture of features manufactured LCDs practical for television receivers. (LCD TV Wikipedia)

In 2007, LCD televisions surpassed sales of CRT-based televisions worldwide for the first time, and their sales figures relative to other technologies are accelerating. LCD TVs are speedily displacing the only major rivals within the large-screen market, the plasma display panel and rear-projection television. LCDs are, by considerably, essentially the most widely created and sold television display type.

LCDs also possess a wide variety of negatives. Other technologies handle these weaknesses, which includes organic light-emitting diodes (OLED), FED and SED, but as of 2011 none of these have entered widespread production.

Many newer technologies, OLED, FED and SED, have lower power use as one in every of their primary positive aspects. All of these technologies directly generate light on the sub-pixel basis, and use only as much power as that light stage needs. Sony has demonstrated 36" FED models displaying really bright images drawing only 14 W, significantly less than 1/10 as considerably as a similarly sized LCD. OLEDs and SEDs are much like FEDs in power terms. The dramatically reduced power demands make these technologies especially fascinating in low-power makes use of like laptop computers and mobile phones. These sorts of units were the market that initially bootstrapped LCD technology, resulting from its light weight and thinness.

LCDs are reasonably inefficient in terms of power use each display size, because the vast majority of light that's getting produced on the back of your screen is blocked earlier than it reaches the viewer. To get started on with, the rear polarizer filters out through half of the original un-polarized light. Examining the image over, you can see that an excellent portion in the screen location is coated by the cellular construction across the shutters, which removes yet another portion. Right after that, just about every sub-pixel's color filter removes the vast majority of what is left to depart only the preferred color. Finally, to manage the color and luminance of the pixel as being a full, the light has for being additional absorbed inside shutters. 3M suggests that, on common, only 8 to 10% in the light getting generated in the again of the set reaches the viewer.

Earlier LCD sets have been widely derided for their poor general image quality, most notably the ghosting on fast-moving images, poor contrast ratio, and muddy colors. In spite of numerous predictions that other technologies would always beat LCDs, enormous choice in LCD production, manufacturing, and electronic image processing has addressed a lot of of these concerns.
