A blazed GxL™ device is described as having high optical efficiency (> 70% for RGB lasers), and high contrast ratio (> 10,000:1), and that is highly reliable when used in a large‐area laser projection system. It has a robust design and precise stress control technology to maintain a uniform shape (bow and tilt) of more than 6,000 ribbons, a 0.25‐μm CMOS compatible fabrication processing and planarization techniques to reduce fluctuation of the ribbons, and a reliable Al‐Cu reflective film that provided protection against a high‐power laser. No degradation in characteristics of the GxL device is observed after operating a 5,000‐ lumen projector for 2,000 hours and conducting 2,000 temperature cycling tests at ‐20°C and +80°C. At the 2005 World Exposition in Aichi, Japan the world's largest laser projection screen with a size of 2005 inches (10 m × 50 m) and 6 million pixels (1,080 × 5,760) was demonstrated.
