长焦黑晶抗光幕-K8

8K长焦黑晶抗光幕-K8     ｜  8K Ambient light rejection Screen Fabric

幕布特点 

黑晶抗光幕采用PVC、聚酯等材料作为基材，表面涂覆黑晶抗光涂层（呈深灰色），通过多次折射光线，降低反射干扰，在环境光干扰下仍能保持色彩鲜艳度和准确度，黑位扎实，金属质感与阳光感表现突出，能吸收80%以上的环境光（如灯光、自然光），尤其在常光环境下可减少画面发白、发灰现象，提升对比度和黑位表现，使画面层次感更鲜明。相比金属幕的高增益但窄视角、易产生光斑的特点，黑晶抗光幕更注重平衡，在保持较大视角（无太阳效应）的同时提升对比度，更适合家用环境。

适用环境：有灯光或自然光（300Lx）环境下使用

适配投影机：高流明4K、8K长焦投影机（投射比 ＞0.4）

适用场所：商务、学校、高端影院、家庭影院、办公会议、KTV等

幕布性能 

Black Crystal anti-glare screen uses PVC, polyester and other materials as the base material, and is coated with black crystal anti-glare coating (dark gray) on the surface. It refracts light multiple times to reduce reflection interference, and can still maintain color vividness and accuracy under ambient light interference. It has a solid black level, outstanding metal texture and sunlight feeling, and can absorb more than 80% of ambient light (such as light, natural light). Especially in normal light environment, it can reduce the whitening and graying of the picture, improve the contrast and black level performance, and make the picture layering more distinct. Compared with the high gain but narrow viewing angle and easy to produce light spots of metal screen, black crystal anti-glare screen pays more attention to balance, while maintaining a larger viewing angle (no sun effect) while improving contrast, which is more suitable for home environment.
