Hitachi has developed a prototype display with an amazing 8 million to one contrast ratio, achieved by combining a traditional LCD display with an LCD projector and multiplying their respective contrast ratios. Designed for dark rooms, the prototype is said to be targeted at a 30cm depth using a short focal-length projector model. The LCD panel sports 1080p resolution, while the rear projector is a standard 720p type. Hitachi also claims that 3D technology could be combined with the same method. Both will be on display at CEATEC Japan in early October. No word on any plans for a plasma / Etch-a-Sketch hybrid display.
