Abstract
A display system is provided. The display system includes a picture generation unit, a diffuser screen, and a curved mirror. The picture generation unit is configured to generate a real image and perform imaging on the diffuser screen. The diffuser screen is configured to perform diffuse reflection on the real image. The curved mirror is configured to perform imaging based on the real image obtained through diffuse reflection, to generate a magnified virtual image.
