Geo, a revolutionary video/graphics-geometry processing chip that makes possible a new class of low-cost, high-performance, rear-projection TVs thin enough to hang on a wall, while also eliminating hot spots and color non-uniformity in LCD and projection displays.


Geo is the first chip to allow for pixel-by-pixel brightness control, thereby ensuring brightness uniformity for large-area LCD panel displays—especially those driven by LEDs, which can vary significantly in brightness. Geo can also correct for a problem, popularly called the “green glob” (pastel-discolored regions), commonly seen in three-panel projection systems.


Geo is the first and only chip to offer three independent geometry-processing channels capable of high-precision, pixel-by-pixel processing capable of digitally achieving lateral chromatic aberration correction, one of the big cost adders in optical system designs.


With Geo, optical problems such as lateral chromatic aberrations, optical distortion, and three-panel misconvergence can be corrected electronically, eliminating the need for more expensive optical and mechanical solutions. Geo’s sophisticated array of adjustments will, for the first time, free designers to create inexpensive RPTVs with cabinet depths that rival those of today’s popular flat-panel LCD and plasma displays—with much less weight and power consumption. Video wall systems with multiple display elements, each of which may have a different brightness, can now be balanced for a more seamless appearance.


“Picture a 55-inch rear-projection TV with a depth of just 5 inches, weighing half of what an LCD or plasma weighs and consuming a fraction of the power. That’s what’s possible with Geo,” said Paul Russo, Chairman and CEO of Silicon Optix. “Geo is going to revitalize the RPTV segment and solve common image-quality problems that have plagued projectors forever. Geo also solves the brightness-uniformity issues associated with LED-driven LCD displays, and the color-uniformity issues associated with three-panel projection systems.”
