IFA 2012: Sharp's stunning IGZO close-up

Sharp's IGZO could be one of the next big advances in LCD technology. On show at this
week's IFA expo in Berlin, it uses a new semiconductor that brings several big advantages over today's
LCD panels.
Guillaume Villecroze, Marketing director, Sharp
"This new technology has a faster response time than LCD panels. It's below 1 millisecond
response time, so this response time allows us to have a very fast panel, better transparency,
and also we can do ultra-high-definition panel. Because thanks to this high transparency,
we can do more pixels in the same surface, increasing the resolution while still having
very good brightness and contrast performance."
The IGZO semiconductor base means smaller transistors and that means smaller pixels
and higher definition panels.
This 6.1-inch display boasts a resolution of 2,560 pixels by 1,600 - that's about 50
percent more pixels per inch than the retina display on Apple's iPhone 4S. You won't see
it on this video, but the screen's display in real life is stunning.
The panel also benefits from lower power consumption. The IGZO panel on the right draws two thirds
less than the conventional LCD and, depending on the image, half as much backlight power.
Another advantage of the smaller transistors is the thinner bezel. Here it's less than
half that of a current LCD panel.
IGZO means transistors don't need to be switched as frequently for static images, and that
means a much quieter electrical environment for touch panels. The IGZO panel on the right
has to fight much lower noise to detect a finger press and that makes for a more accurate
and responsive touchscreen.
Sharp is expecting to begin production later this year.
"We know that this technology is very much applied for mobile products whether they are
tablets, smartphones, PCs maybe as well, so the product planning is undergoing to see
which will be the most applicable fields."
This prototype monitor could be one of the first products to use IGZO. It's targeted
at the CAD/CAM, medical and broadcast imaging markets.
Prices of the displays haven't been announced, but Sharp says it shouldn't be too much more
than current LCDs because it uses the same basic manufacturing process.
