High gain, large viewing angle: gain degree ≥ 4.5 to above 8, high reducibility, high uniformity, comprehensive index K ≥ 100. Good contrast: suitable for projection under normal light, it can completely eliminate the diffuse reflection of the white plastic screen, and the scattered glass bead screen produces a foggy white background phenomenon when projecting under normal light. Good color reproduction: The screen image is clear and lifelike, unmatched by other traditional screens.
