A windshield (100) and a windshield assembly (1000), the windshield (100) comprising an outer glass sheet (10), a polymeric intermediate layer (30) and an inner glass sheet (20), the inner glass sheet (20) having opposite third (21) and fourth (22) surfaces, the third surface (21) facing the polymeric intermediate layer (30), the windshield (100) having an information acquisition area (S1) and a non-information acquisition area (S2); a reflection increasing layer (40) is arranged on the fourth surface (22), the reflection increasing layer (40) covers the information acquisition area (S1) and the non-information acquisition area (S2), and the reflection increasing layer (40) is used for increasing the reflectivity of the non-information acquisition area (S2) to P polarized light of 380nm-780nm; the information acquisition area (S1) is further provided with an outermost dielectric layer (50), the outermost dielectric layer (50) is arranged on the surface of the side, away from the fourth surface (22), of the reflection increasing layer (40), and the outermost dielectric layer (50) and the reflection increasing layer (40) are used for improving the transmittance of the information acquisition area to near infrared rays of 780 nm to 980 nm. The windshield has high transmittance for signals of the laser radar, and meanwhile the head-up display function can be achieved.
一种挡风玻璃(100)及挡风玻璃总成(1000),挡风玻璃(100)包括外玻璃板(10)、聚合物中间层(30)和内玻璃板(20),内玻璃板(20)具有相对的第三表面(21)和第四表面(22),第三表面(21)朝向聚合物中间层(30),挡风玻璃(100)具有信息采集区域(S1)和非信息采集区域(S2);在第四表面(22)上设有增反射层(40),增反射层(40)覆盖信息采集区域(S1)和非信息采集区域(S2),增反射层(40)用于提高非信息采集区(S2)对380nm~780nm的P偏振光的反射率;在信息采集区域(S1)还设置有最外介质层(50),最外介质层(50)设于增反射层(40)远离第四表面(22)的一侧表面,最外介质层(50)和增反射层(40)用于提高信息采集区域对780nm~980nm的近红外线的透过率。挡风玻璃对激光雷达的信号具有高透过率,同时能够实现抬头显示功能。
