> Other than resolution improvements, it would be nice if someone would attempt an HDR light field display. Light field displays just mean even more resolution increases because they're usually created by throwing more pixels at the problem and sticking microlenses over it. Although it doesn't have to be planar, afaik you can also achieve light fields by modifying the phase by altering the properties of the medium in its depth dimension. But you still need to encode a lot more informaation, so whether you have 2D or 3D pixels... you still need more resolution.
