Difference between CRT TV, Plasma TV and LCD TV

After the digital broadcasting starts everyone will need a digital tuner to receive over-the-air signals. When we upgrade to a digital TV, we will not only get all the great benefits of digital broadcast, including theatre-quality picture and sound but also have access to additional digital services. So now let us talk about the difference between CRT TV, Plasma TV, and LCD TV.

  • Limited to about 40-inch screen size.
  • CRT TVs suffer from burn.
  • Longer lifespan than LCD and plasma, lasting over 80,000 hours.
  • Shipping is neither difficult nor expensive.
  • CRT TVs tend to have good contrast ratios than most flat-screen TVs.
  • Installation is straightforward and no professional is required. 
  • More durable than LCD and Plasma TVs.
  • They are Bulkier and are thicker than the flat screen.
  • They weigh more than LCD and Plasma TVs.
  • Better refresh rates compared with Plasma TVs than LCD TVs.
Plasma TV :

  • Average ranges from 32 inches to 63 inches, with Large plasma size 130-inch units and 150 inches.
  • Refresh and handle rapid movement in a video about as well as CRT television, which is about the standard most viewers expect.
  • Suffer from burn-in produced by static images. With technologies such as "pixel orbiter", new plasma TVs have addressed burn-in product life span.
  • Due to their fragile nature, Special shipping methods and their heavier weight add to higher shipping costs.
  • Plasma TVs report higher brightness and contrast levels than LCDs. 
  • Plasmas are heavier, use more power, run hotter than LCD TVs, and therefore require more planning when mounting them. Plasmas are generally best installed by professionals. 
  • Plasmas are best installed by professionals recent improvements to plasma screens have made them significantly more durable and lighter weight.
  • As thin as 3 inches deep.
  • Plasma displays are fairly heavy and may need additional supports to be mounted onto a wall.
  • Average screen sizes range from 13 inches to 65 inches.
  • Originally designed for static data display, and not moving video. LCD TVs are now available with refresh rates specified by manufacturers as low as 5ms.
  • They do not suffer from burn-in but can have a "retained pixel charge" which may also produce ghosting. Stuck pixels are also possible with an LCD display.
  • They 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 may be greater than simply replacing the entire TV.
  • Shipping LCD TVs is not difficult and is not as expensive as shipping plasma displays 
  • They can often look better in 'real-world' situations. LCD TVs reflect very little light, allowing them to maintain levels in well-lit rooms.
  • End users can easily install LCD TVs themselves, or can use them just as they use a traditional TV using a stand.
  • Somewhat more durable than older plasma. 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.
  • As thin as 2 inches deep.
  • LCD TVs weigh less than comparably sized plasma TVs.
