eCinema says it has a true CRT replacement

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 be:

  • Darkest black level output of any TFT in the market
  • Can be used for professional color grading -- previously done using only CRTs
  • Can be used for professional critical picture evaluation -- previously done using only CRTs
  • Allows accurate viewing of intra-field motion on interlaced standards
  • Video displayed at true frame rates for all standards
  • Rugged shock mounted components for field operations

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 environments:

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.

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? That is a ridiculous statement to make that it is better than CRT in every aspect, because it just isn't true.

Now on the other hand I am excited to see real advancement in this technology as it seems to have more legs than Plasma.

CRT's dont have a true black responce because of the light that we do see comming out of a monitor still interferes with the black areas, ive seen monitors and TVs with a slight glow even though they had a black screen at the time.

The subject is not nearly so simple. CRT's don't have an infinite contrast ratio. You measure a CRT via ANSI CR, which is the contrast ratio between alternating black-and-white blocks displayed at once.

However, LCDs are typically measured via a much simpler "On-Off" CR....the ratio of the whitest white to the darkest black they can display...even at separate intervals. This is because LCDs can't dynamically adjust their gamma like a CRT. So OOCR = ANSI CR very closely.

However some newer LCDS *can* adjust their gamma. The dynamic-iris LCD projectors, for one, and the dynamic-backlit HighBrights for another. Measuring such displays with OOCR gives them unrealistically high contrast ratios.

Have you ever looked carefully at a CRT? Yes, the dark areas are darker then an LCD, but they're not black. Not even close. More of a dark grey. Turn off the lights in your room, bring up a black screen, and then turn off the CRT. Notice how the "black" gets darker.
