LCD and Plasma Televisions - a summary on available technologies
The LCD and Plasma Television technology has made some significant progress along the past years.
The LCD television displays a matrix of transistors on a thin film; this matrix gives current to liquid crystal cells located between two pieces of glass. When electricity passes the crystals filter white light; the light is emitted by a lamp behind the screen. LCD monitors reproduce colors through a process of subtraction: They block certain colors from the white light until they are left with the correct color.
The LCD television manufacturers have had many improvements in try to keep up with the plasma television industry and the brightness of their viewing capability.
LCD television producers claim that their televisions last between 50,000 and 65,000 hours.The only anxiety there is with an LCD TV, is the - admittedly - slow decay of the backlight, that can be replaced if this is necessary. You can tell if your backlight is going out if the colors on your television are getting lighter.
Currently, the dominant LCD Television brands in the market are those of Sony, and LG.
The Plasma television has thousands of individual pixel cells that allow electric pulses to execute to the xenon and neon natural gases which in turn causes them to glow and produce the light. This light gives off the balance of red, green, or blue in each cell to display the proper color for you to view.The cells of the pixels resemble light bulbs. If you get up close to a plasma television you will be able to see the pixel cells for yourself.
The plasma television producers claim that these televisions will last about 60,000 hours which is similar to the LCD televisions.
The top manufacturers in the world for Plasma TV panels include Pansonic, LG, Hitachi and Sanyo. RCA is also dynamically involved.
Overall the plasma television seems to have better quality in brightness, sharpness and even perrfection over the leading LCD televisions. Both the LCD and plasma televisions range in price and size but are very price comparable when you look at them side by side. LED televisions are a progressive step in the LCD television technology. The main difference between the plasma television and the LCD television is that the plasma can only be found in a 32 inch television or larger. With the technology changing day after day you will sometime in the future be able to purchase a plasma television that is smaller than a 32 inch.
