2017年8月18日 · INTRODUCTION A high performance Polarizing Beamsplitter (PBS) is essential for creating a viable optical engine for an LCOS projector. Unfortunately, finding a wide angle PBS that provides high performance for a fast beam throughout the visible range has been likened to Captain Ahab’s hunt for a large white whale named Moby Dick1.

硅基液晶LCoS是LCD与CMOS集成电路有机结合的反射型新型显示技术。 其结构是将CMOS基板与ITO导电玻璃上基板贴合，再注入液晶。 LCoS拥有模组体积小、成本低、解析度高、色域广、光利用率高等优势。 目前认为AR市场主流的微显示技术路线是从LCoS到Micro OLED到Micro LED，AR设备厂商已经陆续开始用硅基OLED替代LCoS。 但基于成本上的优势，LCoS+光波导依然是目前常用的方案，本文我们就来了解一下LCoS技术，欢迎大家加群探讨：

2006年1月3日 · Advanced 3M technology in the Vikuiti LCoS optical core permits a brightness level up to 600 cd/m(2). Excellent contrast, combined with high brightness, enables outstanding picture quality. "The Vikuiti LCoS optical core allows a simplified, high performance LCoS solution," said Dr. Robert Melcher, chief technology officer, Syntax-Brillian Corp.

2012年7月5日 · We report the development and the successful product launch of a new 3M Polarizing Beam Splitter, 3M PBSA, which enables high performance optical engines for Liquid Crystal on Silicon LCOS projectors. This PBSA has typical effective transmission of 94% of polarized light with a double pass contrast of around 1500:1.
