Demonstrating a multi-primary high dynamic
range display system for vision experiments
Posted on 2020-04-01 - 13:52
We describe the design, construction, calibration, and characterization of a multiprimary high dynamic range (MPHDR) display system for use in vision research. The MPHDR
display is the first system to our knowledge to allow for spatially controllable, high dynamic
range stimulus generation using multiple primaries. We demonstrate the high luminance, high
dynamic range, and wide colour gamut output of the MPHDR display. During characterization,
the MPHDR display achieved a maximum luminance of 3200 cd/m2
, a maximum contrast range
of 3, 240, 000 : 1, and an expanded colour gamut tailored to dedicated vision research tasks
that spans beyond traditional sRGB displays. We discuss how the MPHDR display could be
optimized for psychophysical experiments with photoreceptor isolating stimuli achieved through
the method of silent substitution. We present an example case of a range of metameric pairs of
melanopsin isolating stimuli across different luminance levels, from an available melanopsin
contrast of 117% at 75 cd/m2
to a melanopsin contrast of 23% at 2000 cd/m2
