If your eyes don't focus on the laptop surface, then each point of
light on that surface is spread out over a larger area.

Since the relative phase of light from different parts of that surface
can't be controlled, destructive interference can't be created, so one
can't put anything on the laptop screen that would be seen as less
blurry than an ordinary sharp display; one can only make things worse.

John Savard

Imagine using a laptop without having to wear corrective
eyeglasses.

I know that 3D displays exist that don't require special glasses.

So maybe this is possible as well?
