Thin CRT screens. When can we expect them?

[MrCoyote]

THIN CRT screens I think are going to overtake regular LCD screens because of the advantages. When can we expect them in the consumer market? Anyone have any opinions on these new displays?

CANDESCENT ABANDONS ITS GRAND PLANS
PRODUCT SHIFTED
50 LET GO
San Jose's Candescent Technologies, a designer of high-tech flat-panel displays that raised more than $600 million in venture capital, is abandoning plans to make its product -- becoming one of the largest start-ups to fizzle in Silicon Valley history.
The company laid off at least 50 of its approximately 100 workers last week, and is now slimming down to a remnant of its former self to license its technology to anyone who will buy it, company leaders and investors confirmed.

It's true that thin CRTs or FEDs (field emission devices) are probably not to appear anytime soon...

But the true focus right now is on OLEDs (organic light emitting devices), with similar or better features.

for example:

LCDs are manufactured in a complex series of steps that combine layers of materials and electronics. LCDs also need backlighting, which accounts for about half of their power requirements. OLED uses thin sheets of film coated with a highly fluorescent material that emits light when electrical current is applied. This electroluminescent film is much easier to produce than liquid-crystal screens, and illuminates the screen much more efficiently than do backlit LCDs, which use an array of polarizers and color filters.

Passive-matrix OLED, suitable for less-graphical displays, uses a simple design of intersecting anode and cathode stripes to create an array of pixels. Active-matrix OLED uses a grid of electrodes, each corresponding to individual pixels on the substrate, to create high-resolution color graphics with a high refresh rate.

Shatzel said that fabrication costs for active-matrix OLED will initially run about 20 percent higher than for LCDs, but will drop to less than 20 percent of LCD production costs as manufacturing capacity ramps up. Kodak researchers are striving to improve the material's current ability to withstand a temperature of 85 degrees (Celsius).

http://kodak.com/country/US/en/corp/pressReleases/pr20011204-01.shtml:
This joint venture agreement extends the February 1999 joint development agreement under which Kodak and SANYO successfully developed the world's first active-matrix full-color OLED displays: a 2.4-inch model in September 1999 followed by 5.5-inch displays in May 2000. This technology can also be extended to produce large displays for personal computers and other devices as the market develops.

Your right OLED holds the promise of the future. To bad about Candesent I actually considers working for them at one time.

I don't suppose you would have a link to this article? I searched the San Jose Mercury News, and found no reference to the above mentioned article.

I used to, however the Merc changed thier web site. Call Candesent and ask.
