Cyril Hilsum, the physicist whose research into stable liquid crystals paved the way for flat-panel televisions and computer screens, has died aged 101. His work at the Royal Radar Establishment (RRE) in Malvern, Worcestershire, in the late 1960s laid the foundation for the ubiquitous displays we use today.
Early Career and the Challenge of Flat Displays
In the late 1960s, the UK government sought to develop miniature radar systems, requiring flat displays to replace bulky cathode-ray tubes. Hilsum, leading a Ministry of Defence team at the RRE, was tasked with this challenge. He realised that liquid crystals—a then-emerging field—held the key to flat-screen technology.

The Breakthrough Collaboration
Hilsum organised a meeting of liquid crystal researchers, where he identified George Gray from Hull University as the only one with deep understanding of the subject. Gray was immediately offered a contract and began working with Hilsum and Peter Raynes, an optoelectronics expert at the RRE. By 1972, the trio had developed a mixture suitable for screens, made largely of cyanobiphenyls—compounds stable even when heated or exposed to sunlight or ultraviolet light. This gave screens durability for real-world applications.
From Radar to Everyday Screens
Although originally designed for radar, the technology quickly found broader use. The stable liquid crystals enabled the creation of flat-panel displays that are now ubiquitous in homes, offices, and public spaces. Hilsum's work not only revolutionised radar but also paved the way for the flat-screen TVs and computer monitors we rely on today.
