As you point out the case spreads out the impulse force from the impact. That decrease the magnitude of the impulse force at any point on the screen. Further, any padding in the case decreases the impulse force by deforming. The net result is that at a point on the screen sees less force and is less likely to be deform beyond it's elastic limits and fracture.
the screens yes -- to a point. but the internals -- NO. the reason being, is that there is no slowed deceleration. when a person jumps off of a building onto an inflated landing zone, they are decelerated. wrap that same person in a bunch of pillows only, and they're still going to get killed or hurt badly. there is no substantial deceleration. wrapping a tablet in a case, is like the pillow scenario....only to a much lesser extent. that is why cases are primarily meant to protect from abrasion, not falls. cases do not offer any protection beyond abrasion, from a physics standpoint.
