This was passed by pretty quickly in lecture, but does this chart imply that we see blue very poorly in comparison to our perception of red and green? I am curious how this manifests in the design of screens, are there a lot more blue pixels because we would need more intensity to see blues better?

Hi AlexSchedel, your observation is correct but in the opposite direction. The S cones have low Quantal efficiency, which means they are less sensitive to small changes in intensity. So in fact manufacturers actaully reduce the number of blue pixels because slightly reduce its number with respect to red/gree pixels do not significantly affect image quality.
Can we say:
