AI Technical Summary
Existing HUD wedge-shaped intermediate films are insufficient in terms of molding precision and long-term dimensional stability, failing to meet the high-precision imaging requirements of AR-HUD and ADAS fusion applications. Furthermore, they are prone to ghosting issues due to environmental aging, affecting driving experience and vehicle safety.
The wedge-shaped intermediate film adopts a three-layer structure, with the middle layer being a sound insulation layer, and the outer and inner outer layers being functional adaptation layers. Combined with wedge die lip extrusion and wedge roll gap precision pressing, a three-stage precision pressing process and precise temperature gradient control are used to improve the forming accuracy and long-term stability of the wedge-shaped intermediate film.
It achieves high-precision molding and long-term dimensional stability of the wedge-shaped intermediate film, completely eliminates imaging ghosting, meets the high-precision imaging and long-term reliable use requirements of AR-HUD and ADAS, and improves the clarity of the driver's field of vision projection and driving safety.
