CRT TECHNOLOGY:
CRTs use a beam of electrons to stimulate phospors and thus make the image. The beam strikes the phospor cells at an angle, however, and this creates a larger spot size. Also, because it is difficult to focus the beam at all points, the image will be less precise in some areas.
|
PLASMA TECHNOLOGY:
Each Pixel contains 3 cells: Green, Red, and Blue. Plasma Display Panels stimulate phosphor cells individually with electrodes. There is no loss of focus.

CRT RESULTS:
- Geometric distortion.
The picture on a CRT will always have a certain amount of distortion.
- Uneven light output.
The picture on a CRT will have areas that are brighter and areas that are darker than others.
- Difficulty focusing across the entire screen.
The picture on a CRT will have some regions that are not as focused as others.
- Picture distorted by magnetic fields.
The CRT's electron beam can be influenced by magnetic fields, which results is a distorted image.
|
PLASMA RESULTS:
- No geometric distortion.
The plasma panel's accurate cell structure produces a picture that is geometrically perfect.
- Even light output.
The plasma panel is perfectly evenly illuminated - no dark or hot spots.
- Perfect focus.
The plasma panel has perfect focus across the entire screen
- No susceptibility to magnetic fields.
The plasma panel is not affected by magnetic fields.
