If rear projection tvs start including this chip in futures tvs, we might actually get a perfect picture every time.

New processor called Geo, which is designed to correct many of the problems endemic to rear-projection TVs. Geo is a geometry processor that compensates for non-uniform brightness and color, such as the infamous “green blob” reported on some Sony SXRD rear-pros (see photo with greenish tint in the left half on the screen) as well as the chromatic aberration that results when white light travels through a lens, causing color fringes around sharp edges in the picture. It also corrects for keystone distortion and rotated images independently for each of the three primary colors.

These functions will enable much thinner RPTVs; whereas current goals target a 60-inch TV with a depth of 10 inches, Geo allows a TV of that size to be five inches deep. this is another technology that could forestall the demise of RPTVs.
