CRT for ME:
LCD's vs. CRT's:
Physical dimensions/size: clearly a solid winner for LCD's here. LCD's are far smaller and weigh substatially less. This difference becomes even more noticeable at larger sizes (a 21" monitors, for example). This can very important in some applications where space is of a priority.
Power: another clear solid winner for LCD's. Max power draw of a typical 17" LCD is ~50W. Max power draw of a typical 19" CRT is ~130W.
Viewing angle: this is nearly a draw in my mind, but probably the CRT wins in most cases. Most people want a high viewing angle (ie. the ability to see things on the screen at a wide angle - like looking at the screen essentially from the side), but in some cases the privacy afforded by the smaller angle of LCD's can be very important (ie. laptops on an airplane). In addition LCD's are making rapid progress in increasing the viewing angle. Max. viewing angle on a CRT is pretty close to 180 degrees. Max. viewing angle on an high-quality modern LCD is 160 degrees but usually lower on a typical screen.
Brightness/Lumination: clear win for CRT's. CRT's can reach 500 cd/m2 or more (click here <
http://physics.nist.gov/cuu/Units/candela.html> for a definition of a candela), whereas a good LCD screen is closer to 200 cd/m2. Although a 200 cd/m2 LCD screen is "good enough" for most indoor applications, the fact that you can always reduce the brightness of a CRT, but can only increase the brightness of an LCD to ~200 cd/m2 is a clear win for CRTs especially in outdoor applications (if size isn't an issue too).
Contrast ratio: clear win for CRT's. Closely related to brightness, it's the ratio of the brightest white to the darkest black. LCD's are around 200:1. CRT's are around 500:1 (notice the correlation to brightness).
Color saturation: a toss-up, but probably leaning towards LCD's. This is a difficult subject despite a clear definition of the property. Both sides claim victory, but probably the LCD's are ahead slightly. On the CRT side though, the color saturation is far more adjustable.
Refresh rate/switching rate: a win for CRT's. This is an area where LCD displays for displays have a bad rap. LCD screens for desktops have made huge progress in this catagory recently. People who quote that LCD displays are too slow are used to the laptop variety (where switching rate is sacrificed for lower power). Switching rates on LCD's and refresh rates on CRT's should not be compared directly, but the general idea is the same. Switching rates on a high quality LCD display can be as high as 90Hz at the max resolution. A high-quality CRT will be better, but 90Hz is more than good enough for most people.
Emissions: Not many people care about this one, but for what it's worth, LCD's have far lower EM radiation emissions than CRT's. It's pretty much a non-issue for most, but for those paranoid people (like my wife, actually) who worry about this stuff then LCD's are the way to go for emissions. (actually she doesn't trust cell phones or microwaves either... she's a bit of a Luddite, actually, which is bizzarre considering she married me... but I digress).
Cost: A clear win for CRT's which generally cost about 50-75% less than a comparable LCD. The smaller the LCD, the better this ratio gets - and at the high-end (21" or higher), LCD's are far more expensive.
Reliability: LCD's are the winner. CRT reliability has increased greatly over the years. CRT's are currently at a MTTF (mean time to failure) of ~19,000 POH (power-on hours), LCD's have a MTTF of approximately ~200,000 POH. This was a hard number to find, and I'm not sure if this is correct. I can imagine that the LCD value will decrease depending on what you consider "failure" (how many dead pixels constitute a failure) and how big the screen is. Still, based on my knowledge of the electronics involved, my gut feel is that I would bet on an LCD screen to last longer than a CRT.
The fact is that the image on a high-end CRT is simply better in all respects compared to the a high-end LCD. LCD's have been gaining very rapidly, and the race is getting closer, but CRT's are still the winner. But, LCD screens are pretty much past the point of "good enough" for most applications. In applications requiring small size or low power, the LCD will always win out over a CRT (imagine a CRT on a digital camera). If image quality is your highest priority then a high-end CRT is the winner. If the application dictates low power or small size, then an LCD is the winner. And if you are somewhere in the middle (like most) then you may go with an LCD for looks or small desk footprint, or a CRT for price.
Edit: throughout this post I have used a 17" LCD screen and a 19" (18" viewable area) CRT monitor as my points of reference. This is not a fair comparison, but it's the sizes that most people consider. Using other screens sizes will skew the results.
