Hitachi Ltd. has developed a 47-inch display that boasts an enhanced dark room contrast ratio of 8,000,000:1.

The display was realized through the adoption of Hitachi's "hybrid monitor technology," which combines an LCD panel and an LCD projector, the company said. Although saying the display hasn't been scheduled for volume production, "We can commercialize it anytime if there is demand from consumers," Hitachi said.

The hybrid monitor technology uses a projector as a backlight system of an LCD panel. Hitachi explained the 8,000,000:1 contrast was achieved through the multiplication of the LCD panel's and projector's contrast ratios. The display renders better gradation in dark scenes since both the LCD panel and the projector control gradation, according to Hitachi.

The LCD panel is a so-called full HD model with a 1980 x 1080 resolution. A VA (vertically-aligned) LCD panel is used. The resolution of the LCD panel used as the projector is 1280 x 720. The panel surface luminance is 700 cd/m2 when displaying white.
