Sanyo Electric Co Ltd developed a front-projection projector that can fill a 100-inch screen at a distance of 63cm.
The projector uses "ultra-short focus projection technology," which combines projector lenses and concave mirrors and projects light from the upper surface of the device. It uses laser as a light source.
The brightness is 7,000lm, which Sanyo claims is "the world's highest brightness among laser projectors." Its color reproduction range is "about twice as wide as that of general LCD TVs," the company said.
It is a DLP projector featuring three 0.95-inch DMDs (digital mirror devices). The display pixel count is 1,920 x 1,080. Screen sizes range from 100 to 150 inches, and the projection distance is 94cm when the screen size is 150 inches.
The throw ratio is 0.28, lower than 0.33 of the company's previous product. Sanyo realized the low throw ratio by using a highly-directional laser light source and developing a fiber rod system that efficiently guides light, it said.
The color gamut is 170% of the NTSC standard. This was realized through the adoption of a laser light source based on the three RGB colors (red, green and blue), which have highly-pure spectra. The projector can render impressive images using Sanyo's "Laser Color Processing (LCP)" image processing technology, which enables to reproduce preferred colors based on scene analyses and human visual characteristics, the company said.
The new projector measures 2,370 x 510 x 630mm. Sanyo expects the projector to be used for signage, presentations in large halls and conference rooms and entertainment at digital cinemas, etc. The company will advance the development with the view to commercializing it in 2012.
