2008年7月9日, CombOLED 研究项目的工作重点是开发出高性价比的生产工艺，以实现有机发光二极管 (OLED) 的量产。欧司朗光电半导体公司固态照明部主管 Bernhard Stapp 表示：“该项目由欧盟提供资金支持，欧司朗负责协调运作，旨在为推行新型照明光源应用创造必要的条件。”这包括采用性价比卓越的方法构建新型元件架构，从而生产出大幅面透明光源。作为 LED 市场的创新推...[详细]
UHF和HF都是一般的技术分类，不过每一类都有独立的支持协议。HF在13.56MHz频段更具有一致性，虽然国际业内行业标准很多。UHF RFID在858-960MHz频段已商业化。同时也有多种国际标准支持，包括EPC global Gen 2。 标签与读写器通过无线链接交换数据。链接可以通过适合任何频段的、具有不同读取范围和抗干扰性的EMF或RF场实现。HF RFID技术主要通过电磁场传送信...[详细]
