Difference between CRT display and plasma display

After the digital broadcasting starts everyone will need a digital tuner to receive over the air signal. When we upgrade to a digital TV, we will not only get all the great benefits of digital broadcast, including theater-quality pictures and sound but also have access to additional digital services. so now let us talk about the difference between CRT and Plasma Display.

CRT technology - CRT uses a beam of electrons to stimulate phosphors and thus electrons to stimulates and thus make the image The beam strikes the phosphor cell at an angle and this creates a large spot size. also, because it is difficult to focus at all points, the image will be less precise in some areas.

 CRT results :

  1. Geometric distortion - The picture on a CRT will always have a certain amount of distortion.
  2. Difficulty focusing across the entire screen - The picture on a CRT will have some regions that are not as focused as others.
  3. Picture distorted by magnetic fields - The CRT electron beam can be influenced by magnetic fields which results in a distorted image.
  4. Uneven light output - The picture on a CRT will have areas that are brighter and areas that are darker than others.
Plasma technology - Each pixel contains 3 cells green, red, and blue. Plasma display panels stimulate phosphor cells individually with electrons. There is no loss of focus.

Plasma results :
  1. No geometric distortion - The plasma panels' accurate cell structure produces a picture that is geometrically perfect.
  2. Perfect focus -The plasma panel has a perfect focus across the entire screen.
  3. No susceptibility to magnetic fields - The plasma panel is not affected by magnetic fields.
  4. Even light output - The plasma panel is perfectly evenly illuminated so no dark or hot spot.
