16:9 Plasma HDTV Screens

The old or original analogue system for television broadcasts was in lines and from the time of the invention of the TV in January 1926, the number of lines was increased from time to tim.
In the UK, the PAL systems stopped with 625 lines and in America the NTSC system of 525 lines was selected.France used SECAM. All three of these systems are being or have been phased out around the world in favour of digital HDTV transmissions of pictures containing between one and two million pixels (dots of light) per frame.
The expression ‘high definition’ is a ‘moving phrase’ since the British Broadcasting Corporation claimed in the late 1930’s that they were broadcasting HDTV. However, by the standards of merely a couple of decades later, it was no longer satisfactory.
Contemporary HDTV is a far cry from the technology of those days. Contemporary digital HDTV wa not even dreamed of then although there were computers already in use in industry. The high resolution of the broadcast images made it crucial to make new kinds of TV sets to receive them. The alternative was a set-top box which would convert the images to analogue lines that the old TV could understand.
All new TV’s are now digital HDTV’s and all transmissions in most countries are just in digital too. So, the move was on to produce affordable HDTV sets. This is where the plasma HDTV set came in. Plasma TV sets were invented in the 1960’s and were in use in the 1970’s but they were extremely costly.
Those early plasma sets were not truly digital because there were no digital signal, but the image was sharper and the colours were truer than purely analogue sets.
The size and shape of contemporary digital plasma HDTV’s was a big topic, because there was a wish among world governments for the standardization of broadcasting. Some countries wanted a screen ratio of 5:3 and others wanted 2.4:1. in the end, the aspect ratio was a compromise and 16:9 was chosen.
Nowadays, TV screens, computer screens, games screens and cinemas all use the 16:9, wide screen aspect ratio. Videos, video games and cinema films are manufactured to look their best on screens of this configuration which has further consolidated the 16;9 aspect ratio as the de facto world norm. You would not be able to purchase a plasma HDTV set that differs from this ratio by any serious amount.
Plasma screens are far slimmer than the traditional TV’s because the technology is completely different. This also permits them to be much lighter.
A plasma digital HDTV is much the same as an oil painting and can be hung on a wall and operated by remote control. Instead of taking up room as an piece of furniture, the TV set has become an item of art.
