Sharp Corp announced Nov 28, 2012, that it will release a 32-inch 4k2k (3,840 x 2,160-pixel) LCD monitor for business use.

Sharp expects that the monitor will be used for CAD (computer-aided design), video making, DTP (desktop publishing), finance, monitoring, etc. The company realized the high resolution and high aperture ratio of the panel by employing IGZO, which is an oxide semiconductor, for the TFTs of the LCD panel. The monitor will be launched Feb 15, 2013, at an expected market price of ¥450,000 (approx US$5,477).

The high resolution and high aperture ratio mean a low power consumption.

"The light use efficiency of the LCD panel was doubled," said Masatsugu Terakawa, executive officer of Sharp. "And the power consumption of the entire LCD module including its driver circuit was reduced by 20 to 30%.

The use of IGZO also contributed to reducing the thickness of the monitor. The enhanced light use efficiency of the LCD panel enabled to lower the brightness of its backlight and to use an edge-lit backlight, which is suited for reducing the thickness of LCD module.

In the past, it was necessary to use a direct-type backlight, which is suited for increasing brightness but increases depth. This time, Sharp reduced the thickness of the entire monitor to about 35mm. As a result, it becomes easy to set up the monitor on a desk, etc and to naturally install it in public spaces, the company said.

The new 4k2k LCD monitor supports DisplayPort 1.2 and HDMI 1.4a. Therefore, it can transmit 4k2k video signals to a PC, etc with one cable.
