Difference between beam penetration technique and shadow mask technique?

Answer 1

Beam penetration

1. Used with random scan monitors.
2. the colors are depends on the speed of the beam.
3. there are only three colours are available red, green, blue.
4. this is not expensive.
5. Quality of picture is not so good.
6. if the speed of read id high then only red color produced.

shadow mask

1. Used in raster scan monitors.
2. there is a shadow mask is used.
3. the colors are depends on the type of the ray.
4. there are millions of the colors are available.
5. it is expensive in the nature.
6. there is no like that speed criteria.

Answer 2

Beam penetration technique uses a focused electron beam to directly strike and illuminate phosphor dots on a screen, while shadow mask technique uses a mask with holes aligned with the phosphor dots to allow electron beams to pass through and illuminate the dots. Beam penetration technique has better focus and resolution but is more complex to manufacture, while shadow mask technique is simpler but can lead to misalignment issues and lower resolution.
