Poeple in the past just invented the tv and the screens were large tubes that were much different than todays plasma screens. Technology has broadened our tv viewing.
HD plasma screens are available on computers. You can hook your computer to the TV via the HDMI port, so that your blu ray drive in your player has the full resolution.
Yes, there is a difference. LCD and plasma technologies continue to improve, but currently the largest television screens are made with plasma screens. Plasma screens produce dark blacks, whereas many LCD screens have problems producing dark blacks and look too light to some people. Plasma screens are going to be heavier than an LCD of the same size usually, and LCDs are more energy efficient.
This is mostly true on the older ones, since the screens held an electrostatic charge. So the electron charge attracts dust that has the opposite charge. If the newer stuff is getting dusty, it is a static charge too, but the device is not actively creating it. Plastic can be prone to building a charge on its own or with rubbing.
The early TV screens were a large tube that was developed from round scopes as used in radar and other electronic devices. The TV Tube was made larger and a little more flat on the edges but the early ones appeared almost round. As technology improved, the TV screens became more and more square. So that is why most screens were square and therefore most TV cabinets were also square. MORE INFO TV screens show film and camera images which are rectangular in shape. To make the TV any other shape would either waste screen area or have to delete some of the original image.
So that you can fit the entire picture onto it and glass is easier to make into squares than it is to be made into round objects.
Very early on - the screens were smaller and there were only 3 channels, the pictures were not as clear and there was often interference or "snow"; most shows were live, so it was kind of interesting to watch - you never knew what would happen
I would like to argue that and say why wouldn't it. It has parts, chips, screens similar to a computer and computer is in involved in science. So, why wouldn't the tv be involved in science?
A cathode ray tube (CRT) was the main way images were presented to people before LCD, Plasma and LED screens were produced. Everyone who watched television or used a computer before 1996 or so watched CRT screens.
The so called LED screens are not trully LED screens. They are simply LCD screens but they have white LEDs for Backlight.
you would need to buy one of those multipurpose flat-screen TV screens that can be used for absolutely anything. (these TV screens can be used for Game consoles, TV, Free view boxes and so on) if you don't want to buy another computer monitor you can call a professional electrician and they can put extra bits on that can be used for Game Console.
HDTVs have become so cheap that now might be the time to buy one. If you are on a budget a normal 60Hz screen will be fine. If you want to spend more you can shoot for 120Hz screens or even a 3D TV.
OLED is the latest display technology to be introduced to the domestic television market. It is impossible to predict the largest OLED television and indeed, a little pointless to look at size as a milestone in LED television technology. OLED allows LEDs to be printed onto a substrate at very small sales so it is ideal for small screens. As the screen size increases, conventional LEDs become more viable than OLED. The largest true LED driven screens are those seen in open air and concerts, up to 40 feet wide or more. At present, commercial factors will decide the largest OLED display to be marketed. Those people who are looking for huge screens still have an option to consider conventional LED displays. Note that LED displays referred to here means the displays that use LEDs to generate the image and not as back lights for LCD displays.
