Abstract
Fact: Blue images always look sharper than white images to the user.
Siemens Display Technologies implemented blue backlights in its flat
panel display product line and had the same feedback from its
customers: bluish pictures look brighter. Therefore we wanted to
research this theme and try to explain this unique “feature” from a
more theoretical point of view. We can explain why, under interior
light conditions, the eye is more sensitive in the bluish domain of the
color spectrum where both spatial resolution and contrast resolution
are optimized. Furthermore, the eye comfort is improved in this
configuration.
