Polymer Vision flexible display surviving extreme weight drop test; industry standard glass display broken.
As the Polymer Vision flexible display absorbs impact energy very efficiently the ball does not bounce up. The glass display is stiff and does not absorb the energy of the ball well. This causes the ball to bounce and the display to break.
Think of it as a ball dropped on a carpet (the Polymer Vision display) or a ball dropped on a concrete floor (the glass display).
