Up Close With Sharp’s Stunning IGZO Display Technology - brownharsecy
In the ongoing race to build ever better flat-screen displays, a possibly disruptive technology has made a small first appearance at IFA, the consumer electronics show presently taking place in Berlin.
In a corner of the booth of Japan's Sharp are respective prototype displays based on a new type of LCD (LCD) called IGZO.
The awkward IGZO nominate is derivative from indium gallium zinc oxide, the semiconductor reincarnate on which the screen is based. Each picture element in an LCD screen is controlled away its own transistor and making those transistors on IGZO brings several favorable characteristics over the amorphous silicon that is in use in now's LCD panels.
Electrons displace faster in IGZO and that brings benefits in current rate of flow that mean the transistors can be made much smaller. Because the size of it of the transistor directly affects the size of it of the pixel, a smaller transistor allows for smaller pixels and so more can make up crammed in per inch than today.
One prototype 6.1-inch screen on show at IFA crammed in 2560 pixels aside 1600 pixels, or 498 pixels per inch. That's a 50 per centum step-up on the 326ppi screen used in Apple's iPhone 4S and just about two-fold that of the new iPad. The conflict is easy apparent: the Perceptive screen displayed a stunningly elaborate see. (See video of the IGZO prototypes at IFA happening YouTube.)
This difference in current flow inside the screen also means that transistors preceptor't have to glucinium continually refreshed when a still mental image is on the screen. That leads to turn down power consumption and, for touch panels, more less interference from the screen's electronics so the touch panel becomes more accurate and sensitive, aforesaid Nobuhiro Okan, a director with Sharp's display twist group.
Okano pointed to a comparison the party was showing between twin 10.8-inch panels that were cycling through a series of still images. A image IGZO panel systematically drew two third less power than an uncrystallised Si panel and the amount of energy used by the backlights happening to each one control panel was always lower on the IGZO screen, sometimes by more than than half.
Another advantage of the little electronics is that the glass edge of each display can be made slimmer, and so portable gadgets could exist made a little small.
Higher resolution in a small screen, lower power consumption, more close touch panels — these are complete things in high-need away the portable gadget manufacture indeed information technology should come as no storm there's been a string of speculation about when IGZO will make it into products, particularly those from Apple.
For now, that remains just speculation. Needlelike hasn't announced any customers and no companies have said they're using the engineering, but if Sharp can deliver on wholly the promises at an affordable cost, it could be making its way into gadgets soon.
IGZO technology has its roots with Tokyo Bring of Technology professor Hideo Hosono, who first synthesized transistors using the semiconductor unit in the mid-'90s. Since then it's been the subject of research and development at scores of companies in Japanese Archipelago, South Korea and Taiwan.
Prototype LCD and OLED screens based around the technology bear been shown, simply it's not until now that a keep company has seriously talked about commercialization of the technology.
Sharp began sample distribution yield of deuce-ac IGZO panels at its Kameyama plant in central Nippon earlier this year: a 7-inch panel for tablets and e-book readers, a 10-inch panel for laptop computers, and a 32-inch panel for professional monitors.
Sharp said it will be ready to begin full production in the fourth quarter of this yr and will initially target the professional market. At IFA the company was showing for the first time a prototype monitor with a 31.5-inch IGZO screen door with 4K resolution (3,840 pixels by 2,160 pixels) that will be targeted at the CAD/Cam River, broadcast and medical imaging markets.
Pricing of the screens hasn't been declared, although Sharp's Okano said information technology wouldn't be substantially more than new LCD panels because the basic manufacturing cost is akin.
