History• There isn't a concrete TV inventor, a

TV is made up of many parts and there was one inventor for each part.

For example the PAL TV inventor was Walter Bruch

• Color Television used the RGB color system that was a useful and cheap way to make a color TV

• This was quite easy to make it working, because the red, green and blue colors were mixed and they could make mostly all the colors that the human eye could see

very poisonous.• The main problem was that they were

too fat and big.

type of television you can se in the stores

subvention.• Normal TV's definition is 480i

is that there aren't many TV broadcast on the world

• You can't see the difference between a normal TV until you plug in a external

HD electronic device (Play station, Blue-Ray, etc).

a normal one• Some 3D TV doesn't need the special

3D glasses but they are the exceptions because the most TV need the 3D

glasses.

Laser TV

• This Type of TV is very new, it is a great advance on TV

• The advantage of a laser TV is that all the colors that the human sight can

see can be displayed on this TV• But the main disadvantage of this type

of TV is that the price is very high in comparison of a HD TV (1500 €)
