LED-Based LCD Display Tested 135
vrioux writes "Tom's Hardware reviews a pre-production NEC SpectraView 2180WG-LED, a new type of LCD display using LumiLED technology, which is a mixture of LED arrays and lightguides. The technology provides near-perfect (98% accurate) color reproduction and uniformity with no apparent downside. This new backlight technology seems like a clear winner for future LCD panels." From the article: "The 2180WG-LED's superiority is overwhelming. 98% of the colors were perfect; and all were at least correct. The result you see is for calibration for the sRGB standard. Unfortunately, the on screen display (OSD) on the model we got from NEC wasn't finalized, so we weren't able to test at other color temperatures. We've asked for a production model so that we can get a better idea of how it performs at 9300K and 5000K."

It uses the LEDs as backlighting for the LCD display.

This particular device blows CRT out of the water. Due to the fact that it uses indepentend sources for reds/blues/green, it can shift the colour temperatur without any need for recalibration the lookup tables.
Because the light source is solid state, it can cover more then the whole adobeNTSC colour space (while CRTs CANT. There is a limit to what you can make phosphor emit by hitting it electrons in terms of spectral cleaness and range)

CRTs flicker because they use a single electron source to scan over all of the pixels on the display, it takes a while (1/60 of a second in the case of a 60Hz display) for it to scan over every pixel and start over at the first pixel, and the pixels slowly dim as they wait to be rescanned and get a sudden surge of brightness as they hit their turn in front of the electron beam.
If each pixel had it's own dedicated electron source that could always be on, there would be no reason for a display to flicker.

The problem is: you cant make one master and put red/green/blue diods on it for normal led processed, because those different colours need different dotations, and base substrates.You cant produce them together. Thus a "LED" display would only work if you would assemble and wire millions of individualy produced diods... And thats not economic in ANY scale.
Thats why oleds are so nice: with organic substrates emitting the light, its a matter of mixing the correct chemicals and then just put the right ones where the pixels should be (simplified). Thus one can produce the displays "per pannel" and not "pixel by pixel".
