Summary: | The utility model discloses a high-gain laser anti-light screen capable of avoiding Moire fringes. The high-gain laser anti-light screen sequentially comprises an AG film layer, a contrast film layer,a light diffusion Fresnel lens layer, a reflecting layer, a protective film layer, an adhesive layer and a honeycomb aluminum plate layer, and the light diffusion Fresnel lens layer is a Fresnel lenslayer in which light diffusion particles are dispersed. The laser anti-light screen is 1.2 in gain, 25 degrees in left and right view angles, 170 degrees in visible view angle, 20000: 1 in contrast ratio, excellent in imaging depth sense, clear in display effect and free of generation of moire fringes.
本实用新型公开了一种可避免摩尔条纹的高增益激光抗光屏幕,依次包括AG膜层、对比度膜层、光扩散菲涅尔透镜层、反射层、保护膜层、胶粘层、以及蜂窝铝板层;所述光扩散菲涅尔透镜层为内分散有光扩散粒子的菲涅尔透镜层。本实用新型激光抗光屏幕增益1.2,左右视角25度,可视视角170度,对比度20000:1,成像景深感优,显示效果清晰,且未产生摩尔条纹。 |
