Always? Then why don't we see more LED based monitors? CRTs aren't bad for color rendition. We've had years to play around with the phosphors, and phosphor chemistry is easier to adjust than semiconductor junctions.
Probably the best system, color-wise, is the DLP projection stuff, where the light source and color filters can be selected separately.
You're an idiot. This discussion isn't about what is currently being marketed to the masses. It is about quality, you retarded sidestep punk.
CRTs are still king, regardless of what is pushed onto the shelves, or how bent your fuched in the head logic is.
The ONLY reason CRTs are not being made in today's large form factor world is that the glass is too hard to make at that span. Otherwise they would STILL be king, and would STILL be being marketed.
SO the ONLY driving factor here is cost of manufacture, NOT quality, dipshit.
CRTs are king and would still rule, if one could get a 50" tube made. One starts running into relativistic problems as well at those spans, however. That one likely went right over your head as well.
Interesting claim. A bit of google searching found no references to this 19 million pixel IBM display. Can you provide some pointers or other information that will allow one to find any more information on it?
When the light source is white (as with a backlit LCD) then the filters in front subtract the light and therefore the three primary filters will make black. Do not confuse this with colour printing.
But you should not consider an LCD like this. Otherwise additive colors made by incansescant lights and R/G/B filters would also be subtractive.
In a backlit LCD, you have a white light source which is regulated from low to high intensity by the LC and polarizers. After that, each pixel has a color filter which makes each pixel a light source being either R,G or B.
Additive color mixing is per definition mixing of colored light, emitted directly from a source before an object reflects the light.
Subtractive color mixing is per definition created by reflected light and colorants that absorb certain colors.
So per definition, anything that makes colored light by itself, by use of light sources, is additive mixing.
