When it comes to flat-screen televisions, two technologies come to mind, LCD (Liquid Crystal Display) and plasma. A lot of people are intrigued about these two types technologies in flat panel and choose between them can be quite a confusing task. If you need to compare LCD TV, Plasma TV, you can find something useful in following information.
Flat Panel Technologies Compared
The LCD screen is composed of two clear panels that have a glass full of liquid between them. These crystals relocate to either block light or let light pass through and the result of millions of crystals to do this is the image on the screen. The action of the crystals is triggered by stress.
Plasma TV, on the other hand, is composed of millions of cells from glass filled with noble gases such as xenon and neon. These cells are illuminated by matches that are activated by electrodes. Each cell contains three different colored phosphors – green, blue and red. As screen LCD, the combination of millions of cells is the image on the screen.
Image Quality and Performance Compared
Brightness – In accordance with independent viewers, LCD TVs are brighter than plasma TVs. On average, plasma screens have higher brightness of about 100 candelas per square meter, while LCD TVs are about 450. This perception of brightness is of course dependent on where the TV is located and is being watched.
Contrast Ratio – contrast ratio measures the distance between the darker Whitest and TV viewing, a high ratio means more detail can be perceived. In the real world LCD TVs have higher contrast alleged relations of up to 450:1 compared to 200:1 for plasma TVs.
Color Saturation – saturation color, measures the accuracy of colors on the screen based on this to shades of gray, shades of gray greater results in less congested. Plasma TVs are known for their high color saturation due to the method that emits light. The ability of plasma pixels to be turned off when not in use avoids the emission of stray light that diffuses color. That is why the hues and colors in Plasma TV are noticeably more vibrant.
Size – Plasma TVs are generally larger than LCD TVs. TVs plasma can be as large as 60 inches but can be as small as 32 inches. LCD screens can be as small as 13 inches but not more than 46 inches. Sizes beyond these limits are being developed, however.
Angle – Pictures in plasma TVs are still clearly visible around 160 degrees and 180 degrees for some models. With LCD TVs, however, the picture becomes dull beyond 100 degrees.
Durability – plasma TVs can last 20,000 to 30,000 hours, which means it could run for about 20 years with an average use of 4 hours per day. LCD TVs last longer, with life expectancy reaching the 50,000 or up to 60,000 hours, which means it can last 40 years with an average daily use of 4 hours.
Cost – since LCD TVs are generally smaller, they are also less expensive compared to Plasma TVs. LCD TVs also use less electricity
