The following table provides a
quick comparison of the display types; "pixelation"
refers to the ability to see individual picture elements
(pixels) at normal viewing distances. Please note that these
products are being constantly improved and not all
manufacturer's models may be subject to the disadvantages
listed below:
DISPLAY TYPE |
PRO - ADVANTAGE |
CON - DISADVANTAGE |
| CRT conventional picture tube |
Very sharp and bright, high contrast ratio, good picture view
from side, low cost, handles regular analog NTSC
channels well, no moving parts |
Heavy and bulky, limited in size to about 36", picture
can fade |
| CRT projection |
Low cost, large screens possible, no moving parts |
Heavy and bulky, limited viewing angles, visible raster
lines, mis-convergence can be a problem, picture can
fade over time |
| LCD Flat Screen Panel |
Bright, sharp picture, light and compact, can hang on
wall, solid state, no moving parts |
Expensive, some pixelation, picture can fade over time |
| LCD projection (micro display) |
Fairly bright, large screens possible, sharp picture, no
moving parts |
More expensive, some pixelation, display can fade due to heat
damage to organic compounds that some manufacturers use
in the LCD, projector bulb can fail |
| Plasma flat screen panel |
Bright picture, light and compact, can hang on wall,
wide viewing angle, no moving parts, handles fast motion
really well |
Expensive, some pixelation, display can burn out. |
| DLP projection (micro display) |
Bright, sharp picture, high contrast, no pixelation, reflective
system won't burn out picture element |
Some visual "rainbow" artifacts on single chip versions
caused by spinning color wheel, projector bulb can fail |
| LCoS projection (micro display) |
Bright, sharp picture, no pixelation, very high
resolution, reflective system won't burn out picture
element, "no moving parts" design usually incorporates 3
imaging chips for primary colors, instead of color
wheel. |
Expensive, limited availability, limited contrast ratio,
projector bulb can fail |
