Head up display laminated glass capable of adapting to high incidence angle and system thereof

The present invention relates to the technical field of display, especially relates to laminated glass in a vehicle and a head up display system thereof, and particularly relates to a head-up display laminated glass capable of adapting to a high incidence angle and a head-up display system comprising the laminated glass. The head-up display laminated glass comprises an inner glass plate, an outer glass plate, and a middle film which is clamped between the inner glass plate and the outer glass plate. The refractive index difference of a high refractive index layer and a low refractive index layer is larger than or equal to 0.5. The middle film can absorb 2% to 18% P polarized light. According to the head up display laminated glass and the system, the P polarized light is absorbed through the middle film, the intensity of the P polarized light which goes through the middle film is weakened, thus secondary image brightness is reduced, no ghosting of the P polarized light in an incidence angle 50 to 68 degrees is realized, no ghosting of the P polarized light in an incidence angle 50 to 72 degrees is realized, even no ghosting of the P polarized light in an incidence angle 50 to 75 degrees is realized, and the head up display laminated glass can be completely adapted to the head up display requirement of a high incidence angle.
