Problems & Opportunities with Projectors New classes of reduced-cost projectors means more and more projectors are used inMore places with uncontrolled lightingPortable applications for business and recreationConventional, vinyl-based front projection screens only work in dark roomsRecent advances in fixed screen technology offer some improvement in lighted rooms, butAre not portableMis-priced for new marketsAre not a mass market solution for projection screens in lighted rooms New projectors require new kinds of screensHigh gainAmbient rejectionPortableLower cost

Objective Figures of Merit for Front Projection Screens

Why High Gain Screens MatterOn-Axis Illuminance of projector/screen-size/gainØv -> Εv -> Lv lm -> lx (lm/m2) -> nits (lm/m2/sr)power -> power/area -> power/area/solid-angle

Gain Trade-OffsOne Dimensional Distribution of Luminous Flux at Various Gains

White diffused reflectance standard with known reflectance (99%)Diffuse Reflectance Source (DS)Luminance meter1) Measure illuminance - reflectance standard (Irs)2) Measure illuminance from SUT (Is)Collimated illumination source, focused to “∞”PhotodetectorIntegrating sphere creating diffused reflectionProjection Screen (SUT)3) Obtain Diffuse Reflectance Source DS = Is / Irs

Competitive Analysis For low & mid-luminance projectors in lighted rooms, screens must have high gain and an Ambient Rejection Ratio (ARR) above 1.3
