1. Structures and Properties of Ferroelectric Liquid Crystal Displays
Abstract : Liquid crystals have unique physical properties as they combine the features of solids and liquids. In thermotropic liquid crystals the degree of order varies with temperature resulting in an appearance of intermediate phases. READ MORE

2. Optical Characterization and Optimization of Display Components : Some Applications to Liquid-Crystal-Based and Electrochromics-Based Devices
Abstract : This dissertation is focused on theoretical and experimental studies of optical properties of materials and multilayer structures composing liquid crystal displays (LCDs) and electrochromic (EC) devices. By applying spectroscopic ellipsometry, we have determined the optical constants of thin films of electrochromic tungsten oxide (WOx) and nickel oxide (NiOy), the films’ thickness and roughness.

3. Investigations of Optical Properties and Photo-Alignment in Bistable Nematic Liquid Crystal Displays
Abstract : In recent years portable electronic devices, such as mobile phones and personal digital assistants, have increased the demand for high performance displays with low power consumption. An interesting candidate with the potential of fulfilling these demands is the reflective single-polarizer surface controlled bistable twisted nematic liquid crystal display. READ MORE

5. Design, Fabrication and Characterization of Microwave Passive Devices on Liquid Crystal Polymer Substrates
Abstract : For microwave/millimeter (mm)-wave systems’ applications, as frequency is moving towards higher and higher bands, materials and integration technologies are witnessing higher performance demands and constraints. The materials presently used as mm-wave substrates are either expensive or show unsatisfactory performance. READ MORE
