Sharp claims LCD has highest contrast

Posted by inet - 2005-10-05

TOKYO — Sharp Corp. has developed an LCD panel that exhibits a contrast ratio of 1,000,000 to 1 the company will aim at the professional monitor market.

Named Mega-Contrast ASV (Advanced Super View) Premium LCD, Sharp claimed that the display goes well beyond self-illuminating displays such as CRTs and plasma displays.

The prototype display, being shown at CEATEC in Japan this week, is a 37-inch panel with full HD resolution (1920x1080) and luminance of 500 candelas per square meter.

"1,000,000 to 1 is the highest level contrast in the industry and is beyond human's sensitivity and also image sensors sensitivity. Video producers and filmmakers required at least 100,000 to 1 contrast ratio for monitors used in their image creation. The contrast ratio of 1,000,000 to 1 will provide enough margin for image creation," said Shigeaki Mizushima, corporate director and group general manager of Sharp's AVC Liquid Crystal Display Group.

Sharp introduced a new structure for the panel and also reviewed various aspects from light scattering to polarization, but Mizushima declined to go into detail about the technology that enabled the high contrast ratio. The backlight uses conventional CCFLs (cold cathode fluorescent lamps).

The display is dedicated for use in a darkroom environment, thus will not be used for home TV sets, Mizushima added.

Presently, professional use monitor displays are all CRT based and deliver a contrast ratio ranging from 10,000 to 1 to 100,000 to 1. Sharp expects to offer Mega-Contrast LCD monitor display for use in broadcast stations and film studios in various sizes with various sizes from 10 to 65 inches.

The display also offers advantages for use as an LCD monitor in relay vans for TV broadcasting because it is free from geomagnetism intervention.

"I learned that the professional use monitor market is about 20 billion yen ($180 million) world-wide. We want to take over the market with Mega Contrast monitors eventually," said Mizushima.

Sharp plans to introduce the display over the next year.
