LCD: Liquid Crystal Devices
  • Lecture Theatre 006, Babbage Building

Save event

This lecture is organised by the Institution of Engineering and Technology (Devon and Cornwall Local Network) and will be given by Dr Garry Lester, Technical Director, L-lectronics Ltd.

Liquid crystal devices familiar to us as seven segment, laptop and now TV displays. 

Liquid crystals are however much more versatile and lend themselves to a wide range of applications. The presentation will begin with an introduction to the different types and phases of Liquid Crystals and some of the different optical effects that are available for exploitation. Though it is difficult to talk about liquid crystals without reference to displays, other applications will also be illustrated to give a flavour of the wide variety of things that can be done with them.
