High Definition Television

High-Definition-Television (HDTV) displays pictures that contain significantly more detail, resulting in much 'crisper' pictures.

Images viewed on TV screens are made up of small picture elements known as 'pixels.' Each of these pixels is made up of three, closely spaced 'dots' of colour - red, blue and green.

Combined together on the TV's phosphor screen, and viewed from a distance, the colours are seen as one. The phosphor at each of these dots emits light directly proportional to the intensity from the electron beam that hits it, as it scans across the screen.

Get up close to an analog screen - especially the larger projection sets - and you can easily see the red, blue and green rectangles. This is why distortion is sometimes seen on traditional TV's.

The pixels in HDTV sets are square; they are also smaller, and spaced closer together. The result is that High-Definition-Television can display at least 4.5 times more detail than analog TV.
