Increased contrast ratios are essential to the continued success of DLP™ products in the marketplace, from rear projection televisions and home theatre systems to large venue displays and DLP Cinema™. The contrast of DLP projection systems has increased steadily over the past 5 years due to improvements in illumination and projection optics, as well as changes to the DMD itself. The authors will present an overview of contrast performance of DLP projectors over time as well as describe illumination and projection techniques that optimize the performance of the DMD.
