The patent summary shows that the eye-protecting macro rear-projection MIP LED display screen of the present invention includes a substrate layer, a MIP LED package, a diffuser, an anti-reflection layer and a sub-wavelength grating structure layer. The MIP LED packages are distributed in an array on the substrate layer; the diffuser is located on the substrate layer and covers the MIP In the LED package, the side of the diffuser facing toward the substrate layer is provided with a number of cavities, and the side of the diffuser away from the substrate layer is provided with a plurality of prism portions. The positions and numbers of the cavities and prism portions respectively correspond to the MIP LED package; the anti-reflection layer is provided on the surface of the side of the diffuser with the prism portion; the sub-wavelength grating structural layer is provided on the anti-reflection layer. Among them, the diffuser can homogenize the original LED point light source into a surface light source as much as possible, thus achieving uniform light and soft light. The light effect alleviates the pixel graininess and dazzling brightness of the LED screen; the sub-wavelength grating structural layer can effectively block blue light, reduce the potential damage of blue light to human eyes, and improve the eye protection effect.
