     Wide-screen TV-viewing distances

With wide-screen sets showing DVD or HDTV, you can sit as close as 1.5 times the screen's diagonal measurement and not notice any loss in quality, while sitting farther away than three times the screen size means you're likely to miss out on the immersive feel. Here's a rundown of minimum and maximum recommended viewing distances for wide-screen sets.

LCD - Liquid Crystal Display

LCD's are colour television sets which use LCD technology to produce images. LCD televisions

are thinner and lighter than CRTs (Cathode Ray Tubes) of similar size, and are available in much larger sizes.
This combination of features made LCDs more practical than CRTs for many roles, and as manufacturing
costs fell LCD became increasingly dominant.

Plasma

A plasma display panel (PDP) is atype of flat panel display common to large TV displays (32" inches or larger). Many tiny cells between two panels of glass hold an inert
mixture of noble gases. The gas in
the cells is electrically turned into
a plasma which thenexcites phosphors toemit light. Plasma displays should not be confused withLCDs, anotherlightweight flatscreen display using
different technology.

High Definition

High-definition television (or HDTV)
is a digital televisionbroadcasting
system with higherresolution
than traditional television systems (standard-definition TV, or SDTV).
HDTV is digitally broadcast; the earliest implementations
used analog broadcasting,
but today digital television (DTV) signals are used, requiring lessbandwidth due to digital video compression.
