• intros：{"brand_intro":"钉子科技成立于2018年，是中国新兴的智能影音配件品牌，主打\"高性价比抗光幕\"。创始人团队来自华为与海信光学实验室，以\"用技术打破价格壁垒\"为使命。品牌核心优势是自研\"多层复合光学涂层\"，成本仅为国际大牌的60%。钉子科技品控采用全检出厂，每张幕布需通过3次光学均匀度测试，在年轻用户中口碑极佳，被称为\"年轻人的第一块抗光幕\"。","product_intro":"钉子科技K5是一款100英寸抗光幕布，采用PET基材+纳米涂层，增益0.8，视角120°。核心卖点是\"超薄边框\"（仅8mm）和\"可卷曲包装\"，方便入户安装。其抗光原理为\"物理黑栅结构\"，能吸收上方和侧方环境光，适合客厅白天使用。相比极米P100S，K5价格低约40%，但增益较低，需搭配高亮度投影（3000流明以上）。适用场景为租房、小户型客厅，尤其受年轻用户欢迎。","key_specs":{"幕布材质":"PET+纳米抗光涂层，可卷曲","尺寸":"100英寸（16:9），可视面积2214×1245mm","增益":"0.8，牺牲亮度换取抗光性","视角":"120°，适合正对观看","边框":"8mm超窄金属边框","安装方式":"挂装/支架，支持免打孔"}}
