摘要:
A tapered interlayer and windshield employing the same are provided. Unlike conventional windshields, which are optimized to reduce ghost images for a single driver height, the windshields of the present invention may exhibit reduced ghosting for drivers of multiple heights, including very tall or very short drivers, while also providing desirable image clarity for average-height drivers. Windshields as described herein may be used in a variety of applications, including automotive, aircraft, marine, and recreational vehicles that employ HUD projection systems.
摘要:
A wedge-shaped interlayer having reduced dynamic ghosting 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.
摘要:
A tapered interlayer comprising at least one polymer layer and a having tapered zone with an overall wedge angle of not more than 0.85 mrad is provided. The refractive index of the polymer layer is 1.480 or higher. Multiple layer panels formed from such interlayers may exhibit desirable optical properties, including, for example, less image "ghosting," when used as part of a heads-up-display (HUD) display panel for use in automotive and aircraft applications.
摘要:
Multilayered interlayers having good acoustic properties comprising a stiff skin layer(s) and a soft core layer(s) are disclosed. The multilayered interlayers comprise: a first polymer layer (skin layer) comprising plasticized poly(vinyl acetal) resin; a second polymer layer (core layer) comprising plasticized poly(vinyl acetal) resin; wherein at least one plasticizer is a high refractive index plasticizer. The multilayered interlayers have low mottle and resist mottle formation.
摘要:
Windshields are disclosed herein having an optical path, that include an inner rigid substrate, optically adjacent a first wedge polymer layer, that serves to reflect a primary image. A reflective layer is also provided, positioned in the optical path between the first wedge polymer layer and a second wedge polymer layer. The windshields are further provided with an outer rigid substrate, optically adjacent the second wedge polymer layer. The first wedge polymer layer causes visible light reflected from the reflective layer to overlap the primary image, and the second wedge polymer layer causes visible light reflected from an outer face of the outer rigid substrate to overlap the primary image.
摘要:
Polymer interlayers having improved gradient bands and laminates comprising these interlayers are disclosed. The polymer interlayers and laminates comprising polymer interlayers have a gradient band that has a high level of gradient beauty from the perspective of visible light transmittance spectra.
摘要:
An interlayer comprising a first polymer layer, a polarization rotary optical film and optionally a second polymer layer, and multiple layer panels formed from such interlayers. The panels may exhibit desirable optical properties, including, for example, less image "ghosting," when used as part of a heads-up-display (HUD) display panel for use in automotive and aircraft applications.
