Designing with TFT LCD Column Drivers
July 30, 2002 Online Seminar

Overview:
This seminar will present useful information to successfully design with TFT-LCD column drivers.  The focus will be on methods and explanations not found in datasheets.  This includes a discussion of asymmetric gamma curves, static and dynamic Vcom characteristics, content specific gamma, output offset issues and proper routing and layout of differential pairs.

Presenter:
Dick McCartney has been involved in displays for more than 20 years and with the design of active-matrix, LCD drive electronics for the last 15.  He is Principal Display Technologist at National Semiconductor focused on the development of new product technology for display applications.  He is also Technical Program Chair for the 2003 Society for Information Display Symposium.

Topics covered in this online seminar include:

  • Construction of the Column Driver          
  • Theory Behind Setting Gamma Correction          
  • Differential Signal Routing          
  • Output Variation Issues
