Venue: 78-420

Host: Dr Aleksander Rakic

Abstract:

 
  As technology advances, mobile electronic devices such as laptop
  computers, cellular phones or digital cameras have emerged as a
  necessity in ones everyday life. This has boosted the demand for
  light and reliable flat panel displays that come along with those
  devices. Since early ninety's, liquid crystal display (LCD) has
  became the dominant source of display due to its distinct properties
  in size and reliability. However, LCD as a mature technology does
  have its limitations and this has prompted engineers in search for a
  better and reliable alternatives.

  Organic light emitting diodes (OLEDs) are attracting increasing
  attention for applications in display devices due to their high
  brightness and wide viewing angle. However, major obstacles such as
  luminance efficiency, light extraction efficiency and long term
  stability still exist in the technology awaiting
  solutions. Recently, microcavity structures have been employed on
  existing OLED device to alter electroluminescent (EL)
  characteristics of organic material and enhancements in light
  emission spectrum and extraction efficiency have been observed.
  While there has been significant progress in this area over recent
  years, comprehensive device simulation and design studies have been
  scarce. This project aims to develop a set of design guidelines that
  will optimise the performance of microcavity based OLED in aspects
  including emission intensity, directivity and light extraction
  efficiency.

  This seminar will begin by examining current LCD technology and its
  limitations, followed by the literature review of the OLED
  technology. The major obstacles of OLED will be outlined and project
  aim will be determined. The research methodology detailing how the
  problem should be approached will be addressed. The results obtained
  up to date will be presented and the contribution of the thesis will
  be emphasized. Finally, the remaining research tasks will be
  identified and concluded with nominal completion dates.
