The Plessey Company plc was a British electronics, defence and telecommunications company. It originated in 1917, growing and diversifying into electronics. It expanded after World War II by acquisition of companies and formed overseas companies.

Plessey Semiconductors specialises in advanced microLED technology for AR/MR wearable devices, HUDs and other consumer electronic displays.

Siemens Plessey was the name given to the Plessey assets acquired by Siemens in 1989. Today most of these units are part of BAE Systems while some units are now part of EADS.

2025年1月15日 · 近期，专注于嵌入式技术及 AR/VR/MR 显示应用的 Micro-LED 技术供应商 Plessey Semiconductors 宣布，与 Meta 合作成功研发出号称“全球最亮”的红色 Micro-LED 显示屏，专为 AR 眼镜设计。 据 Plessey 透露，这款新型红色 Micro-LED 显示屏在保持高分辨率（小于 5 微米）的同时，亮度竟高达 600 万尼特，且功耗极低。 回顾去年，Meta 曾震撼发布其 AR 眼镜原型“Orion”，而 Plessey 对此赞誉有加，认为它是“横跨几乎所有现代计算领域”的划时代发明。

2019年10月11日 · Plessey最新的专利生长方式，是在同一片晶圆上同时创建原生蓝光和绿光发射层。 两种颜色集成的方式，大大简化显示屏的制造过程。 其中，绿色Micro LED具有高效能和窄光谱宽度，当它与高效能的蓝色Micro LED一起使用时可产生出众的色域。

2023年7月25日 · Plessey是全球少数能够量产MicroLED AR显示屏的公司之一，其技术路线是通过巨量转移技术，把MicroLED芯片焊接在高密度线路的CMOS背板上，提供小型化微显示器给行业使用。

Plessey is one of Britain's largest electronics manufacturers. Primarily involved in the design and development of communications systems, it has in recent years been an excellent case study in corporate revivals. As late as 1979, Plessey was in such poor shape that it was touted as an industrial garage sale waiting to happen.

Plessey is an innovative technology, design and manufacturing company. Drawing on many years of semiconductor and optoelectronics expertise, Plessey has developed an award-winning, unique and proprietary GaN-on-Silicon platform and monolithic processes at its state-of-the-art manufacturing facility in Devon, UK.

Plessey’s microLEDs enable compact displays that enhance the user’s experience, for both entertainment and informative content, and is the first brand new display technology to be commercialised in more than a decade.

2019年9月23日 · 19日，英国硅基氮化镓（GaN-on-Si）专家Plessey宣布开发了一个创纪录的2.5μm超高分辨率Micro LED显示屏，用于可穿戴AR/VR设备。 Plessey一直致力于将Micro…
