Talk about eye candy! The IBM T221, a 22.2-inch LCD monitor, offers such a stunning image that we feel we must warn you: There is no going back. This may be a slight problem because of the $18,999 price tag for the display (code-named Big Bertha by the engineers at IBM's T. J. Watson Research Center in Yorktown Heights, New York). As a lease, that's $672 for 36 months?much more than a Jaguar S-Type's current $499 lease.
"The T221 offers a whole new relationship with data," says Steven L. Wright, research staff member at IBM's Advanced Display Technology Laboratory. "Before Bertha, we were looking at data through a soda straw." Take legal documents: Bertha renders the 4-point type with ease and clarity. Or the Japanese language, which requires 170 pixels per inch: Bertha maxes out at 204 pixels per inch. Or a regular PDF file: Bertha can display two letter-size pages side by side.
Bertha's core technology is a jumble of the latest letters: It uses an active-matrix TFT LCD panel with dual-domain in-plane switching (IPS) technology. It has a resolution of 3,840-by-2,400, which allows for 12 times as much data as a 1,024-by-768 monitor. (That's QUXGA-W, for Quarter-UXGA Wide; the wide part comes from the 16:10 aspect ratio, which is just slightly bigger than a typical movie screen's.) Another way to look at it: That's 9.2 million pixels. Two DVI outputs simultaneously channel the digital signals, and four bricks supply AC power.
Almost every aspect of Bertha's inner workings is brand-spanking new. Aluminum was used as a gate material, and newly developed liquid crystals were injected in an innovative process called One Drop Fill. These two advances make faster response times possible, solving one of the major bugaboos of LCD screens. In conjunction, the engineers developed Post-Spacer technology?permanent spacers that provide super-sealing capabilities to prevent light leakage. And the breakthroughs just keep coming: A new protocol called Digital PV link updates only the pixels that need updating, which reduces bandwidth strain.
Call it a game of catch-up. Displays are way behind compared with today's powerful processors, graphics cards, and 5-megapixel digital cameras. When you order a computer online, the display is the last item you pick, yet it's the component you interface with most. But Bertha's brilliance won't matter much if the industries involved can't get together. Take DVI, the new digital standard for monitors. It's power is undercut by confusion over too many types of adapters: DVI-A, DVI-D, DVI-I, and so on. Worse is the lack of support from graphics card vendors; only a few high-end cards currently support DVI. A little synchronization from key players, continued improvement from IBM and others, a bit of a price drop, and we could all be feasting our eyes on our own Berthas soon.
