LED-Based LCD Display Tested
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."
They are in use, but still only for small displays such as phones and mp3 players. Expect to see the same trend for any new display technology, as it is much easier to manufacture small displays than large ones.
Trust the Computer. The Computer is your friend.
I've seen one of these in action before; color reproduction/quality was amazing. It was the first time I'd seen a non CRT display that I'd be willing to use for photo work.
Um... no.
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.
