Bright‐room contrast measurements methods are being proposed by 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.
