Q3、公司调光导电膜主要采用哪种技术路线，优点缺点如何？ 答：目前市场主流的调光膜技术分为 PDLC（聚合物分散液晶）、 SPD（悬浮粒子）、LC（染料液晶）和 EC（电致变色）四种。公 司开发的调光导电膜系列产品覆盖了前述的这四种主流技术，目 前在售的产品以 EC 为主，应用于汽车天幕、侧窗、后视镜等场景。 优缺点来看，EC 电致变色路线优点在于低电压，耗电少，断电情 况下仍然能保持原色，变色倍率、雾度性能都较优，缺点在于变 色速度相较于其他路线慢。PDCL 以及 PDCLC 路线的优点在于变色 快，但是雾度偏高，从公司导电材料的角度看，对方阻要求不高， 技术壁垒相对较低。SPD 最主要是工作电压高，耗电且雾度也偏 高。 证券代码：003015 证券简称：日久光电 江苏日久光电股份有限公司投资者关系活动记录表 编号：2025-009 | ☑ | 特定对象调研 □分析师会议 | | --- | --- | | 投资者关系活动类 | □媒体采访 □业绩说明会 | | 别 | □新闻发布会 □路演活动 | | | □现场参观 | | | □其他 （请文字说明其他活动内容） | | 活动参与人员 | 宁银理财 高晗 ...
