Rear-projection display system and rear-projection screen

A rear-projection display system, comprising a projector, N light path turning systems, and a rear-projection screen, wherein N is a positive integer;

• the rear-projection screen comprises a collimation lens layer comprising a target region and a Fresnel lens region, wherein the target region is arranged outside the Fresnel lens region;
• and emergent light exiting the target region is parallel to the normal of the collimation lens layer;
• the projector is configured to emit first projected light which is incident directly onto the Fresnel lens region, and emit second projected light which is incident onto the N light path turning systems, wherein an emitting angle of the first projected light is lower than a first preset threshold, an emitting angle of the second projected light is above or equal to the first preset threshold, and the emitting angle is an angle between the projected light emitted by the projector, and an optical axis of the projector;
• and
• the N light path turning systems are configured to receive the second projected light emitted by the projector, and to have the second projected light incident onto the target region at a first angle less than the emitting angle of the second projected light.
