According to Hitachi the 8,000,000:1 contrast ratio is achieved through "the multiplication of the LCD panel's and projector's contrast ratios."
Hitachi claims that "the display renders better gradation in dark scenes since both the LCD panel and the projector control gradation."
The company said it doesn't currently have plans to mass produce the system, but could introduce it fairly quickly if reaction to the demonstrations indicates strong potential demand.
Using a newly announced "short focal-length projector technology," Hitachi said it can reduce the depth of the display to around 11 inches.
