Not really. Fundamentally things like this are driven by physics, not engineering or cleverness.
We've had solar powered calculators with LCD displays for decades. We're not really going to get much lower power without changing Fundamental technologies at the material and physics level. Much of what we have material and physics wise "is what it is", on this planet anyway.
