LCD Vs plasma
Plasma is also known as gas plasma because of between the glass layers it has gas and LCD is known as Liquid Crystal Display. As well as the name says the LCD has Liquid in between the layers.
Power Consumption : comparison of interst to consumers. LCD TVs typically spec lower for power consumption than an equivalent size plasma.
Thickness : plasmas are As thin as 3 inches deep. And LCDs are As thin as 2 inches deep.
Weight : Plasma displays are fairly heavy, and may need additional supports to be mounted onto a wall.
LCD TVs weigh less than comparably sized plasma TVs.
Screen sizes : Average screen sizes range in plasma TV from 32 inches to 63 inches (measured on the diagonal). Larger plasmas, like a 103 inch unit from Panasonic, are in production, but are still prohibitively expensive for consumer use. Panasonic has announced plans to release a 150-inch plasma display by 2010.
LCD TVs Average screen sizes range from 13 inches to 65 inches (measured on the diagonal). As with plasma, there are larger LCD TVs made, like a 108 inch display which is to be released in later this year (2008) by Sharp, but they are not readily available or affordable at the consumer level.
Viewing Angle : Up to 178°. Plasma images do not suffer from the same degradation at higher viewing angles that LCD TVs do because of the nature of the technology. LCDs Up to 175°.
LCD TVs were originally designed for a one user experience, As the applications for the technology grew for larger to larger displays and audiences , an issue with viewing angles emerged. Although the LCD TV can be viewed from up to 176 degrees, there is a "sweet spot" which will produce brighter, higher contrast images.
Refresh Rates : Plasma displays refresh and handle rapid movements in video about as well as CRT televisions, which is about the standard most viewers expect. LCD TVs were originally designed for static data display, and not moving video. Therefore refresh rates had to be improved.
LCD TVs with refresh rates below 16 ms or lower (5-15 ms) show very few noticeable artifacts. LCD TVs are now available with refresh rates specified by manufacturers as low as 5ms.
Product Life-span : Plasma TVs have a reported half life of 30,000 to 60,000 hours. Half-life is the time it takes the lamp to fade to half its original brightness. Panasonic recently reported life span's approaching 100,000 hours.LCD TVs have a backlight that is specified to last between 30,000 and 60,000 hours.
LCD TVs also have replaceable backlights, but the expense of replacing one when the time comes may be greater than simply replacing the entire TV.
Durability : Plasmas are somewhat fragile making them tricky to ship and install. Unlike the commercials where plasmas are mounted on the ceiling, plasmas are best installed by a professional, and should be installed on a wall that can bear a good deal of weight. However, recent improvements to plasma screens have made them significantly more durable and lighter weight.Somewhat more durable than older plasmas.
End users can easily mount an LCD TV themselves if desired, although LCD TVs should still be shipped with special care, and the screen itself should be cleaned with a streak free cleaner.
Shipping : Due to their fragile nature, plasma TVs need to be shipped by specialty carriers. Overnight or fast delivery options are not recommended. Special shipping methods and their heavier weight add to higher shipping costs.
Shipping LCD TVs is not difficult, and is not as expensive as shipping plasma displays.
Installation : Plasmas are heavier, use more power, and run hotter than LCD TVs, and therefore require more planning when mounting them. Plasmas are generally best installed by professionals.
End users can easily install LCD TVs themselves, or can use them just as they use a traditional TV using a stand.
Brightness & Contras : Plasma TVs report higher brightness and contrast levels than LCDs. Under ideal conditions (no ambient light) this is a true advantage of plasma technology, because LCD TVs are backlit and therefore light must be blocked to create blacks. Plasmas have individual pixels that either on or off, creating deeper blacks and better contrast.
LCD TVs can often look better in 'real-world' situations. Plasmas are made with a special glass surface that can reflect light, which dulls the brightness and contrast of the image. LCD TVs reflect very little light, allowing them to maintain levels in well-lit rooms.
Performance at High Altitude : High altitudes can affect the performance of plasma displays because the gas held inside each pixel is stressed, and has to work harder to perform. Some manufacturers make plasmas that are specifically designed for high-altitudes, but they may be priced higher than standard models.
LCD TVs are not affected by high altitudes.
These are the comparison of LCD and plasma. Decision is in your hand what would be the best for you? Make good Decision it save your money.
