LCD or Plasma

0

We quite often get questions from users whether they should buy a LCD or a Plasma Television. The following information might help you to make the right decision.

Advantages LCD compared to plasma

– Sharper image, good for still images such as computer display
– Comes also in smaller sizes
– Lower pricing, especially below 30 inches
– No image retention (burn in), plasma screens can suffer image retention if a still image is left on the display for a extended period of time.

Disadvantages LCD compared to plasma

– Artifacting (image delay problem, see Response time below)
– expensive over 35 inch
– Digital looking picture, colors look less natural

Response time

An LCD TV consists of liquid crystals with a large backlight shining behind it. Because of this an LCD has always a certain delay. When a fast moving object moves across a LCD screen the delay of LCD technology causes “artifacting” Basically there are trails or blockiness of the image since the screen cannot keep up.The higher the reponse time the more “artifacting”. Some older models shave a response time of 10 milliseconds, or even higher. If you can afford it the best choice would be to choose an LCD TV with a response time of around 5 ms (millisecond). With a good name brand LCD TV the artifacting is minimal and really wont be noticeable until you get a screen over 30 or 35 inches.

Resolution

The resolution of an LCD TV is determined by the number of pixels in each dimension that can be displayed. The higher the resolution, the higher the detail the picture holds. A pixel (picture element) is the smallest image on a screen, one imagepoint.

The resolution of LCD TVs is increasing. 1366×768 is the most common resolution. It is expected that the most important resolution will be 1920×1080. This resolution is also called full HD. At a resolution of 1920×1080 is the image density so high that the picture quality is very sharp, almost like a photograph. Blu-ray and HD-DVD players are also ready to run at a resolution of 1920×1080. Also the newest generation game consoles as the Xbox 360 and the Playstation3 support this standard.

HDTV

Since the first HDTVs appeared high-definition television has been an important issues for every TV buyer. In South Africa SABC and MultiChoice have tested HDTV broadcasting locally, but both have cautioned local consumers not to expect the commercial availability of HDTV before 2009. The current television signals exist of 576 TV lines. A signal can be called High Definition (HD) Television (TV) when the signal has at least 720 lines in stead of 576. A LCD or plasma TV can only carry the HD ready logo when the screen can distribute this resolution of 720 lines completely and is equipped with one of the following connections.
