Sharp unveiled the much awaited proof of pudding for the IGZO (indium gallium zinc oxide) LCD panel technology. IGZO acts as a superior substrate material to amorphous silicon, thanks to higher electron mobility, and lets you achieve either higher pixel density, or faster response times. Sharp chose the former, and launched the PN-K321. This 32-inch professional desktop/workstation monitor packs a native resolution of 3840 x 2160 pixels.
To draw those many pixels from its source, it relies on DisplayPort, although HDMI is also available. It is priced at the equivalent of US $5,500, and could be unveiled stateside at CES 2013 (January).
