Metrology and robustness of bright-room contrast measurements

Abstract

Bright-room contrast measurements methods are being proposed in standards committees to characterize flat panel displays for living-room ambient environments. Some proposals involve creating a room with an overhead light. By modeling the room as a sphere, we show how such room-based measurement methods can be very irreproducible. Such methods can be modified and made robust by making direct-source measurements combined with integrating-sphere-based diffuse reflectance measurements.
