When it comes to flat TVs, two technologies come to mind, LCD (Liquid Crystal Display) and Plasma. A lot of people are puzzled about these two types of flat screen technologies and choosing between them can be quite a bewildering task. If you need to compare LCD to Plasma TV, you may find something useful in the following information.
Flat Screen Technologies Compared
The LCD screen is comprised of two clear panels that have a crystal-filled liquid between them. These crystals reposition themselves to either block light or let light pass through and the result of millions of crystals doing this is the picture on the display. The action of the crystals is triggered by voltage.
Plasma TV, on the other hand, is composed of millions of small glass cells filled with rare gases such as xenon and neon. These cells are lit by phosphors that are activated by electrodes. Each cell contains three different colored phosphors - green, blue and red. Like in the LCD screen, the combination of the millions of cells forms the image on the display.
Picture Quality and Performance Compared
Brightness - according to independent viewers, LCD TVs are brighter than plasma TVs. On the average, plasma screens have brightness ratings of about 100 candelas per square meter while LCD TVs have around 450. This perception of this brightness is of course dependent on where the TV is located and what is being watched.
Contrast Ratio - contrast ratio measures the distance between the darkest and whitest display of the TV, a high ratio means greater details can be discerned. In the real world, LCD TVs reportedly have higher contrast ratios which can amount up to 450:1 compared to 200:1 for plasma TVs.
Color Saturation - color saturation measures the accuracy of the colors on screen based on the present of gray shades, higher gray shades results into lower saturation. Plasma TVs are famous for their high color saturation due to the method it emits light. The ability of Plasma...
