Used LED TV for Sale
Analysts were surprised to find that not only had LCD outsold plasma, but CRTs as well, during the same period.This development drove competing large-screen systems from the market almost overnight. Plasma had overtaken rear-projection systems in 2005.The same was true for CRTs, which lasted only a few months longer; Sony ended sales of their famous Trinitron in most markets,Pioneer Electronics was ending production of the plasma screens was widely considered the tipping point in that technology's history as well.
LCD's dominance in the television market accelerated rapidly. It was the only technology that could scale both up and down in size, covering both the high-end market for large screens in the 40 to 50" class, as well as customers looking to replace their existing smaller CRT sets in the 14 to 30" range. Building across these wide scales quickly pushed the prices down across the board.
In spite of LCD's current dominance of the television field, there are several other technologies being developed that address its shortcomings. Whereas LCDs produce an image by selectively blocking a backlight, OLED, FED and SED all produce light directly on the front face of the display. In comparison to LCDs, all of these technologies offer better viewing angles, much higher brightness and contrast ratio,and better color saturation and accuracy, and use less power. Also, in theory they are less complex and less expensive to build.
