More Information
Summary:A wedge-shaped interlayer having reduced dynamic ghosting and reduced dynamic transmitted imagery variations is provided, wherein the interlayer comprises at least one polymer layer comprising a poly(vinyl acetal) resin and at least one plasticizer, wherein said wedge-shaped interlayer defines a head-up display (HUD) region having a target vertical wedge angle, an actual vertical wedge angle and an absolute wedge angle rate of change, wherein the absolute wedge angle rate of change is less than 3.0 prad/mm throughout the entire HUD region, and less than 3.0 prad/mm outside the HUD region.
