What Is the Difference Between Lcd and Led?

Both have a liquid crystal display screen. The only major difference between the two is that older or less expensive sets use a fluorescent lamp for the backlight, while an "LED" set uses a bank of light emitting diodes. The LED backlighting uses less electrical power than the fluorescent lamp. There are two versions, "edge" lighting and "full matrix." Edge-lit sets can be very thin. Full matrix sets allow for "local dimming," which can bring improved contrast in specific areas of the screen. New for 2011: some of the latest model edge-lit sets also provide for a certain degree of local dimming. However, do not look for a *major* difference in picture quality. The HD picture on an "LED" set will be difficult to distinguish from a very good conventional LCD set.

1. LCD Non HD TV Bulb Replacement?

Lamps run from $100 to $200. Could be other problems also. Lamps are not returnable.

2. which is best lcd or plasma ?

The choice is yours.....but hope this helps..the url was Too long... Plasma vs LCD The ADVANTAGES of Plasma over LCD are: 1. Larger screen size availability. 2. Better contrast ratio and ability to render deeper blacks. 3. Better color accuracy and saturation. 4. Better motion tracking (little or no motion lag in fast moving images). The DISADVANTAGES of Plasma vs LCD include: 1. Plasma TVs are more susceptible to burn-in of static images. 2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images. 3. Does not perform as well at higher altitudes. 4. Potentially shorter display life span - this used to be the case. Early Plasmas had 30,000 hours or 8 hrs of viewing a day for 9 years, which was less than LCD. However, screen life span has now improved and 60,000 hour life span rating are now common, with some sets rated as high as 100,000 hours, due to technology improvements. LCD television ADVANTAGES over Plasma include: 1. No burn-in of static images. 2. Cooler running temperature. 3. No high altitude use issues. 4. Increased image brightness over Plasma. 5. Lighter weight (when comparing same screen sizes) than Plasma counterparts. 6. Longer display life used to be a factor, but now LCD and Plasma sets both have at least 60,000 hour or higher lifespans. DISADVANTAGES of LCD vs Plasma televisions include: 1. Lower contrast ratio, not as good rendering deep blacks. 2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts) - However, this is improving with the recent implementation of 120Hz screen refresh rates and 240Hz processing in higher-end LCD sets. 3. Not as common in large screen sizes above 42-inches as Plasma. However, the number is growing fast, with 46 and 47-inch screen sizes becoming more common, and some LCD sets having a screen size as large as 65-inches also available to the general public. 4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you. 5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions (although this is changing), especially when comparing EDTV Plasmas to HDTV-LCD Televisions.

3. Which is better Plasma or an LCD TV?

LCD: you get more pixels per inch, so you get a higher resolution, but the colors are not as vibrant. PLASMA: less pixels, but brighter colors and darker blacks. now that they are more developed, you wo not get the image burned on the screen. ***NEW TECH*** LED LCD: you get the same number of pixels as and LCD screen, but also the same color as a plasma. great product

4. LCD or Plasma what are the pros and cons?

They are both good sets, we live in Colorado and at this altitude plasma does not work as well as LCD. So it may depend on where you live
