Sharp has launched a 32″ 4K resolution (3840×2160) touch-screen IGZO-based monitor. You may recall that IGZO (Indium gallium zinc oxide) is a TFT LCD that uses much smaller transistors behind each pixel — thus allowing more light pass an  is also considered as one of the most promising TFTs to eventually drive organic light-emitting diode (OLED) displays. In the case of Sharp’s IGZO displays, their aperture ratio of the LCDs are improved by up to 20 percent, and their power consumption is as much as 50 percent less than traditional TFTs. Here’s Sharp’s info site on IGZO.

The PN-K322B 4K LCD from Sharp is available in both a touch screen and non-touch version and will be 32″ diagonal with a 350 cd/m2 of brightness. It’s an edge-lit LED-based LCD offering DisplayPort, HDMI and network content ports. And, it will scale 2K to 4K. And, for those of you who go, ho-hum, reading the 2K to 4K scaling line — you’re wrong. Don’t overlook this. Scaling 2K (or 1080p) to 4K looks incredible — even with crappy scalers. This new model will officially debut in November and will have 10 touch points and can be mounted horizontally, vertically or flat.

We saw it (and took a photo) at the Whitlock Convergence Show last week in Durham, NC. Mac Rumors is also reporting that Sharp showed the display at CEATEC in Japan earlier this month using Mac OS X with full touch support.

All the specs are here.
