LCD panels have traditionally been lagging behind CRT
monitors in terms of color response, saturation, accuracy and overall
black-level response. Because LCDs are "always lit" by a backlight,
deep dark blacks have been the Achilles heel of LCD technology. However, a
company named eCinema Systems has announced a new LCD
technology that it claims surpasses CRT in virtually every respect.
eCinema's new LCD technology is being called high dynamic range LCD, and also
supports "deep color", which is higher than 24-bit color, starting at
30-bit or 36-bit and can go up to 48-bit. The new panels are able to display
36-bit color (12-bits per color channel), and 1000 to 4000 step gray-scales,
producing fantastic gradients. Most LCDs today produce only 256 gray steps at
most. This new "deep color" technology will be standard with the new
HDMI 1.3 specification. What's most spectacular about eCinema's LCD display
however, is its contrast ratio: 30,000:1. At this rating, eCinema's new
DCM40HDR panel can achieve black levels that even CRTs cannot match. eCinema
CEO Martin Euredjian said:
"It is well known that LCD displays did not until now produce the same
deep blacks that were achievable when using a CRT. Color depth is, of course,
the 8 bit bottleneck issue. Images on the screen -- at the pixel level -- are
limited to a best-case of 256 levels between black and white. In other words,
if you painted a gray scale you could, at most, see 256 steps. The reality of
the matter is that due to calibration and gamma adjustments most displays can't
do much better than about 200 steps between black and white."
eCinema will be launching its new DCM40HDR 40-inch LCD by Q4 of this year. The
new panel will be a true 1080p display and will be suitable for professional
applications where only CRTs were used. Key features of the DCM40HDR will
If eCinema's displays perform well, this could mean higher
quality LCD panels across the industry. The company says that its DCM series of
LCD panels are reference-grade monitors suitable for critical viewing
Production and Post can now discuss color with accuracy, confidence and
reliability. Post production partners can work on common projects knowing that
all work is viewed on precisely matched no-maintenance monitoring systems. In
addition to this, clients can evaluate in-progress or finished work remotely
while assured that the colorist saw exactly what they are seeing.

quote: The thing is that 30000 to 1 sounds impressive, but CRT has,theoretically, an infinite contrast ratio which is why it never report the contrast ratio. Having deeper blacks levels than CRT make absolutely no sense either because CRT blacks are created by the absence of light, which is black. So this statement is saying blacker than black, huh?
quote: I find it curious that they only talk about the fact that they can get deep blacks, what about the whites? Not saying that this is what they did but it's possible for a monitor to have a tinted screen in order to get deep blacks, but then whites would look, well, not white.
