Polarization cannot "straighten" the light path. Light from an LCD display is already polarized that is an integral part of how LCD screens work. If the phone was an OLED screen like most of the newer ones polarization would have the effect of cutting light output by over 50%. Not helpful for curing or focusing the light. Based on what they are showing in the promo video it looks like magic.
