The invention provides laminated glass and a projection system. The laminated glass is provided with a light-transmitting area and a shielding area; the display area has an S light reflection spectrum curve for S polarized light which is incident at the incident angle of 70 degrees and has the wavelength of 380 nm to 780 nm, the S light reflection spectrum curve only has one extreme point within the wavelength range of 450 nm to 650 nm, and the position of the extreme point has the minimum value RLsmin of S light reflectivity. According to the laminated glass and the projection system provided by the invention, the contrast ratio of a display image and a display background can be improved, a higher color gamut is realized, and the image is displayed more clearly; and moreover, the laminated glass also has higher P polarized light reflectivity, smooth P polarized light reflection spectrum and lower S polarized light reflectivity, so that the effects of reducing the energy consumption of a projector, reducing the reflection interference of a center console and realizing neutral reflection imaging with less color cast or no color cast are achieved, and the display effect is further improved.
本申请提供了夹层玻璃及投影系统。夹层玻璃具有透光区以及遮蔽区;显示区对以70°入射角入射的波长为380nm‑780nm的S偏振光具有S光反射光谱曲线,S光反射光谱曲线在450nm‑650nm的波长范围内仅有一个极值点,且在极值点处具有S光反射率最小值RLsmin。本申请提供的夹层玻璃及投影系统可以提高显示图像与显示背景的对比度以及实现更高的色域,使图像显示更清晰;并且,夹层玻璃还具有较高的P偏振光反射率、平滑的P偏振光反射光谱、以及较低的S偏振光反射率,从而达到降低投影机能耗、降低中控台反射干扰、反射成像中性少色偏或无色偏的效果,进而提高显示效果。
