Enabling TCAD for TFT, LCD & OLED Display Designs

This webinar will provide an insight into different TCAD-based simulation techniques that designers of TFT, LCD and OLED display can make use of. First, we will discuss both electrical and optical TCAD simulations of LED/OLED diodes. Next, we will explore LCD simulation and analysis including calculation of transmission patterns at various wavelengths and applied voltages. Lastly, we will discuss how to model device degradation in amorphous a-IGZO TFT devices which is the most important issue when large area and high definition pixel are designed.

  • TCAD simulation of LED/OLED diodes including J-V and I-L characteristics, and internal and external quantum efficiencies
  • Learn about techniques to simulate and analyze Liquid Crystal Displays
  • Simulation of TFT degradation in the amorphous semiconductor a-IGZO
    • TCAD models for degradation in an oxide semiconductor
      • Mechanisms of degradation
      • Process simulation of hydrogen thermal diffusion
      • multi-state trap model/ion reaction-diffusion model


Steve Broadbent is a Senior TCAD Applications Engineer at Silvaco Boston. He has been working for Silvaco for 18 years, supporting customers and their use of TCAD for a wide range of materials, processes, and device applications from CMOS to QWIPs, and from HEMTs to Lasers and OLEDs.
