Sharp reveals 32-inch 4K IGZO monitor

Sharp has just unveiled a new professional-grade 32-inch monitor with a 4K UHD resolution, which is built using IGZO technology.

The Sharp PN-K321 monitor isn’t just as big as an entry-level living room HDTV – it’s around four times as sharp. It boasts a 3,840 x 2,160 resolution, which is known as UHD or 4K.

Previously we’ve only really seen this new standard of display resolution in huge high-end TV sets, such as the 84-inch Sony KD-84X9005 or the 55-inch Toshiba 55ZL2. Here, though, Sharp has crammed all those pixels into a 32-inch form factor.

This is made possible by IGZO technology. IGZO – which stands for Indium gallium zinc oxide – is a special semiconducting material that can be used in the thin film that drives such displays. The improved flow of electrons that it facilitates means that as well as being highly energy efficient, it also allows for smaller pixels. The end result of this is the potential for much higher resolutions in much smaller form factors.


The Sharp PN-K321 comes with HDMI and DisplayPort inputs, as well as an ultra-slim frame of just 35mm. Sharp is calling it “the industry’s thinnest design.”
As you may expect, this is intended for professional use by photographers and designers, and there’ll be a price tag to match when it launches in February 2013. The Sharp PN-K321 will cost 450,000 yen, or £3,437 going by today’s exchange rate.

Expect to see a lot more of IGZO and the UHD standard at CES 2013 from January 8.
