Disadvantages

• Requires screen-sized memory array

• Discrete spatial sampling (pixels)

• Moire patterns result when shadow-mask and dot-pitch frequencies are mismatched

• Convergence (varying angles of approach distance of e-beam across CRT face)

• Limit on practical size (< 40 inches)

• Spurious X-ray radiation

• Occupies a large volume

Advantages

• Allows solids to be displayed

• Leverages low-cost CRT H/W (TVs)

• Whole Screen is constantly updated

• Bright light-emitting display technology
